When you register a plug-in in Microsoft CRM all kinds of things can go wrong. Most commonly, the error I get is "An error occurred."
When you look for more detail you just get: "Server was unable to process request" and under detail you see "An unexpected error occurred."
Not very helpful. However, there are some good answers out there if you really dig. Anybody out there encountered this and how do you fix it?
The most common issue is that the meta parameter names must match.
For example:
public static DependencyProperty householdProperty = DependencyProperty.Register("household", typeof(Microsoft.Crm.Sdk.Lookup), typeof(AssignHouseholds));
[CrmInput("AccountId")]
[CrmReferenceTarget("account")]
public Microsoft.Crm.Sdk.Lookup household
{
get
{
return (Microsoft.Crm.Sdk.Lookup)base.GetValue(accountidProperty);
}
set
{
base.SetValue(accountidProperty, value);
}
}
Note the name after DependencyProperty (housedProperty) must exactly match the string after DependencyProperty.Register (in this case ("household") with the word "Property" appended.
Also, that value must match the value of public variabletype (in this case "household"). If any one of them don't match, it will error.
This is by design and is how MSCRM ties the values together.
A common cause is that your CRM SDK references must use the 64 bit version if you are on a 64 bit machine.
These will be located at
C:\sdk\bin\64bit\microsoft.crm.sdk.dll
and
C:\sdk\bin\64bit\microsoft.crm.sdktypeproxy.dll
if you installed the sdk to C:\sdk.
Also your build settings should be set to "Any CPU" under Project properties->Build.
You may also need to move the two dlls to your debug or release folder before you build.

I am a student who begin to study SHOP2 from China.
My teacher told me to run JSHOP2 in Eclipse.Now I can run original zenotravel problem and generate GUI and plans.Likewise, I want to put other domain and problems to SHOP2 and produce plans.
But the problem is that I don't know how to compile them and My teacher only asked me to run the the main function in Internaldomain but it can't succeed.Follow is the original code:
public static void main(String[] args) throws Exception
{
//compile();
// compile(args);
//-- run the planning algorithm
run(args);
}
This code can run zenotravel.Then I put domain and problems named pfile1 and
tdepots respectively into SHOP2 folder.Change the codes to:
{
compile(domaintdepots);
// compile(args);
//-- run the planning algorithm
run(args);
}
It warns "domainpdfiles cannot be resolved to a variable".
Or
//--compile();
compile(args);
//-- run the planning algorithm
//run(args);
It turns out:
"Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
at JSHOP2.InternalDomain.compile(InternalDomain.java:748)
at JSHOP2.InternalDomain.main(InternalDomain.java:720)"
720 is main funcition above.And 748 is compile function:
public static void compile(String[] args) throws Exception
{
//-- The number of solution plans to be returned.
int planNo = -1;
//-- Handle the number of solution plans the user wants to be returned.
if (args.length == 2 || args[0].substring(0, 2).equals("-r")) {
if (args[0].equals("-r"))
planNo = 1;
else if (args[0].equals("-ra"))
planNo = Integer.MAX_VALUE;
else try {
planNo = Integer.parseInt(args[0].substring(2));
} catch (NumberFormatException e) {
}
}
Finally,according to the advice of the friend,I put the two pddls into src folder and use “java Jshop2.InternalDomain domaintdepots”in CMD commad but an error appeared:"the main class Interdomain can't be found or loaded".But I have set the class path accurately and the Zenotravel planning can run.So how
and where can I use the command ？
And what is written in the bracket"compile()" in Eclipse？
I am also not familiar with JAVA so it's better if there is concrete instruction.Thanks a lot.
Please describe what are you trying to build, what is it supposed to do, what is the expected end result.
If you do have a valid PDDL domain and problem file, you could try to load them into the online http://editor.planning.domains/ editor using the File > Load menu. Then press the Solve button and confirm which of the file is the domain and which is problem. If the PDDL model is valid (and the underlying solver can handle the requirements), you will get a plan back.
If you are trying to build a software solution that needs a PDDL-based planning engine as one of its component, perhaps you could use one of the available implementations: https://nergmada.github.io/pddl-reference/guide/whatisplanner.html#list-of-planners
If you are trying to build your own planning engine in Java using the Eclipse IDE, you probably need a Java-based PDDL parser. Here is a tutorial, how to use pddl4j for that purpose:
https://github.com/pellierd/pddl4j/wiki/A-tutorial-to-develop-your-own-planner
If you need to use Jshop2 in particular, it looks from their documentation (http://www.cs.umd.edu/projects/shop/description.html) that you need to indeed compile the domain and problem PDDL into Java code using following commands:
java JSHOP2.InternalDomain domainFileName
java JSHOP2.InternalDomain -r problemFileName
Edited on June 19th
Java package names (e.g. JSHOP2) and class names (InternalDomain) are case sensitive, so make sure you type them as per the documentation. That is probably why you are getting the "main class not found error".
It is difficult to say what the lines numbers 748 and 720 exactly correspond to, because in the GitHub repo https://github.com/mas-group/jshop2/blob/master/src/JSHOP2/InternalDomain.java the code is different from yours. Can you indicate in your questions which lines those are exactly?
The make file shows how to execute an out-of-the-box example in the distribution:
cd examples\blocks
java JSHOP2.InternalDomain blocks
java JSHOP2.InternalDomain -r problem300
Does that work for you?
Like the title says, is it possible the tutorial at https://www.arangodb.com/tutorials/spring-data/ is outdated? I'm having several problems, but don't know how to workaround the last one:
Part 2, "Save and read an entity"
I get an error: method getId() is undefined.
Workaround: I added a getter in class Character.
Also in "Save and read an entity"
final Character foundNed = repository.findOne(nedStark.getId());
The method findOne(Example) in the type QueryByExampleExecutor is not applicable for the arguments (String)
Workaround: I used find by example:
final Optional<Person> foundNed = repository.findOne(Example.of(nedStark));
Part 1, "Create a Configuration class"
public class DemoConfiguration extends AbstractArangoConfiguration {
Gives me an error:
"No constructor with 1 argument defined in class 'com.arangodb.springframework.repository.ArangoRepositoryFactoryBean'"
Workaround: ?
Can anyone point me in the right direction?
I found the demo project on github: https://github.com/arangodb/spring-data-demo
Number 1: They use a getter too.
Number 2: Was my fault, I did try ArangoRepository (of Character, Integer) but forgot that Id is a string.
Number 3: They don't seem use any Configuration (AbstractArangoConfiguration) class in the source at all although it is still mentioned in that tutorial. I think now the config and connection is handled by spring autoconfigure. Though I would like to know how the Arango driver is set, all I could find that may point further is ArangoOperations.
Anyway it works now, maybe this helps somebody else who is having the same problems.
I have a strange MEF problem, I tested this in a test project and it all seems to work pretty well but for some reason not working in the real project
This is the exporting code
public void RegisterComponents()
{
_registrationBuilder = new RegistrationBuilder();
_registrationBuilder
.ForTypesDerivedFrom(typeof(MyType))
.SetCreationPolicy(CreationPolicy.NonShared)
.Export();
var catalog = new AggregateCatalog();
catalog.Catalogs.Add(new AssemblyCatalog(typeof(MyType).Assembly, _registrationBuilder));
var directoryCatalog = new DirectoryCatalog(PathToMyTypeDerived, _registrationBuilder);
catalog.Catalogs.Add(directoryCatalog);
_compositionContainer = new CompositionContainer(catalog);
_compositionContainer.ComposeParts();
var exports = _compositionContainer.GetExportedValues<MyType>();
Console.WriteLine("{0} exports in AppDomain {1}", exports.Count(), AppDomain.CurrentDomain.FriendlyName);
}
exports count is 0 :( Any ideas why?
IN the log file I have many of this
System.ComponentModel.Composition Information: 6 : The ComposablePartDefinition 'SomeOthertype' was ignored because it contains no exports.
Though I would think this is ok because I wasn' interested in exporting 'someOtherType'
UPDATE: I found this link but after debuging over it I am not wiser but maybe I m not following up properly.
Thanks for any pointers
Cheers
I just had the same problem and this article helped me a lot.
It describes different reasons why a resolve can fail. One of the more important ones is that the dependency of a dependency of the type you want to resolve is not registered.
What helped me a lot was the the trace output that gets written to the Output window when you debug your application. It describes exactly the reasons why a type couldn't be resolved.
Even with this output. you might need to dig a little bit, because I only got one level deep.
Example:
I wanted to resolve type A and I got a message like this:
System.ComponentModel.Composition Warning: 1 : The ComposablePartDefinition 'Namespace.A' has been rejected. The composition remains unchanged. The changes were rejected because of the following error(s): The composition produced multiple composition errors, with 1 root causes. The root causes are provided below. Review the CompositionException.Errors property for more detailed information.
1) No exports were found that match the constraint:
ContractName Namespace.IB
RequiredTypeIdentity Namespace.IB
Resulting in: Cannot set import 'Namespace.A..ctor (Parameter="b", ContractName="namespace.IB")' on part 'Namespace A'.
Element: Namespace.A..ctor (Parameter="b", ContractName="Namespace.IB") --> Namespace.A --> AssemblyCatalog (Assembly="assembly, Version=0.0.0.0, Culture=neutral, PublicKeyToken=...")
But I clearly saw a part for Namespace.IB. So, in the debugger, I tried to resolve that one. And I got another trace output. This time it told me that my implementation of Namespace.IB couldn't be resolved because for one of its imports there was a missing export, so basically the same message as above, just with different types. And this time, I didn't find a part for that missing import. Now I knew, which type was the real problem and figure out, why no registration happened for it.
I was using Breeze v1.1.2 that came with the Hot Towel template which has now been extended to form my project. I made the mistake of updating the NuGet package to the current 1.3.3 (I never learn). Anyway, all was well, and now not so much!
I followed the instructions in the release notes and other docs to change my BreezeWebApiConfig file to:
[assembly: WebActivator.PreApplicationStartMethod(
typeof(BreezeWebApiConfig), "RegisterBreezePreStart")]
namespace MyApp.App_Start {
public static class BreezeWebApiConfig {
public static void RegisterBreezePreStart() {
GlobalConfiguration.Configuration.Routes.MapHttpRoute(
name: "BreezeApi",
routeTemplate: "breeze/{controller}/{action}"
);}}}
And the config.js file (which provides the serviceName to the EntityManager constructor) to:
var remoteServiceName = 'breeze/breeze'; // NEW version
//var remoteServiceName = 'api/breeze'; // OLD version
And my BreezeController if you're interested:
[BreezeController]
public class BreezeController : ApiController
{
readonly EFContextProvider<MyDbContext> _contextProvider =
new EFContextProvider<MyDbContext>();
[HttpGet]
public string Metadata()
{
return _contextProvider.Metadata();
}
[HttpGet]
public IQueryable<SomeItem> SomeItems()
{
// Do stuff here...
}
}
Now I get the "cannot execute _executeQueryCore until metadataStore is populated" error.
What am I missing here?
EDIT:
I perhaps left out the part you needed... Above in the SomeItems() method, the stuff that actually gets done is a call to the GetMeSomeData() method in the MyDBContext class. This method makes the following call to a stored procedure to get the data.
public virtual ObjectResult<SomeItem> GetMeSomeData(string inParam)
{
var p = new object[] { new SqlParameter("#inParam", inParam) };
var retVal = ((IObjectContextAdapter)this).ObjectContext.ExecuteStoreQuery<SomeItem>("exec GetData #SN", p);
return retVal;
}
Now given my limited understanding, the call to Metadata() is not failing, but I don't think it has any idea what the entity model is when coming back, even though somewhere along the line, it should figure that out from the entity model I do have (i.e. SomeItem)? The return string from Metadata() doesn't have any information about the entity. Is there a way to make it aware? Or am I just completely off in left field playing with the daisies?
Hard to say based on this report. Let's see if Breeze is right.
Open the browser debugging tools and look at the network traffic. Do you see an attempt to get metadata from the server before you get that error? If so, did it succeed? Or 404? Or 500? What was the error?
I'm betting it didn't even try. If it didn't, the usual reason is that you tried some Breeze operation before your first query ... and you didn't ask for metadata explicitly either. Did you try to create an entity? That requires metadata.
The point is, you've got to track down the Breeze operation that precipitates the error. Sure everything should just work. The world should be rainbows and unicorns. When it isn't, we heave a sigh, break out the debugger, and start with the information that the error gave us.
And for the rest of you out there ... upgrading to a new Breeze version is a good thing.
Happy coding everyone.
Follow-up to your update
Breeze doesn't know how you get your data on the back-end. If the query result has a recognizable entity in it, Breeze will cache that. It's still up to you in the query callback to ensure that what you deliver to the caller is something meaningful.
You say that you're server-side metadata method doesn't have any idea what SomeItem is? Then it's not much use to the client. If it returns a null string, Breeze may treat that as "no metadata at all" in which case you should be getting the "cannot execute _executeQueryCore until metadataStore is populated" error message. Btw, did you check the network traffic to determine what your server actually returned in response to the metadata request (or if there was such a request)?
There are many ways to create Metadata on the server. The easiest is to use EF ... at least as a modeling tool at design time. What's in that MyDbContext of yours? Why isn't SomeItem in there?
You also can create metadata on the client if you don't want to generate it from the server. You do have to tell the Breeze client that you've made that choice. Much of this is explained in the documentation "Metadata Format".
I get the feeling that you're kind of winging it. You want to stray from the happy path ... and that's cool. But most of us need to learn to walk before we run.
I am specifically getting the following error:
"The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid."
[TestMethod()]
public void salesOrderFillListTest()
{
SalesOrderController_Accessor target = new SalesOrderController_Accessor();
string orderNumber = "1954120";
SalesOrderData result;
result = target.FillingOrder(orderNumber);
Assert.AreEqual(null, result.ErrorMessage);
Assert.AreEqual(32, result.LineItems.Count);
Assert.AreEqual("WRA-24-NFL-CLEV", result.LineItems[7].ItemNumber);
Assert.AreEqual(2, result.LineItems[7].OrderQuantity);
Assert.AreEqual(1, result.LineItems[7].FillingFilledQty);
Assert.AreEqual(1, result.LineItems[7].FillingRemainQty);
}
The error is coming up on the line:
result = target.FillingOrder(orderNumber);
I'm a junior developer and haven't had much experience with the many possible causes for this error. My App.config page contains the appropriate connection strings. Any ideas where to look for this one?
Thanks!
I was able to successfully run tests found in another test project in the same solution. After looking more carefully I found that there were a few differences between the two connection strings in each project. The data in the failing test project had become antiquated. I updated the connection string and error resolved.
Thanks.
