ArangoDB "Spring Data Demo" Tutorial outdated? - spring-data

Like the title says, is it possible the tutorial at https://www.arangodb.com/tutorials/spring-data/ is outdated?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.

talend - name of components in tStatCatcher

I'm having trouble displaying the label of my components properly in tStatCatcher. I have renamed my components label but upon logging of tStatCatcher's origin field, the name is still the previous one.
E.g. Renamed my tDatabaseInput from MY_QUERY from tDatabaseInput1
tStatCatcher is still displaying tDatabaseInput1. It should be the new name MY_QUERY.
Anyone can provide assistance.
Thanks in advance
You can't delete the technical name of the component, it will always appear in logs as tComponent_1, to ensure unicity.
What you can do is adding MY_QUERY to the technical name, using __UNIQUE_NAME__
It will still not appear in your log, but you'll be able to see that MY_QUERY is linked to tComponent_1.
For example :
[]
I'm not sure if this is the best answer. But I'm sticking to this implementation for now unless someone shared a much better way.
I created a routine java class with a method that maps the from the tStatCatcher's row.origin to my hardcoded list of label names:
public static String mapToLabel(String uniqueName) {
switch(uniqueName) {
case "tDatabaseInput1":
return "MY_QUERY";
default:
return "--not mapped";
}
}
Then I called this method on my tMap's expression editor.

Property Mapping Exception in Helhum upload example

I am using helhum File Upload Demo to upload the images. But currently i got below error.
Exception while property mapping at property path "images.0":Property "name" was not found in target object of type "XXXX\XXXXX\Domain\Model\FileReference
Please help here.. How can i move forward.
Thanks in advace.
If you followed the example extension, you are maybe missing the registration of UploadedFileReferenceConverter and ObjectStorageConverter in your ext_localconf.php. Took me a day to find that one:
ext_localconf.php
\TYPO3\CMS\Extbase\Utility\ExtensionUtility::registerTypeConverter('Vendor\\EXT\\Property\\TypeConverter\\UploadedFileReferenceConverter');
\TYPO3\CMS\Extbase\Utility\ExtensionUtility::registerTypeConverter('Vendor\\EXT\\Property\\TypeConverter\\ObjectStorageConverter');
In the initializeUpdateAction (or initializeCreateAction) you have to use the name of the parameter in the updateAction (or createAction) as argument.
If your updateAction looks like this:
public function updateAction(\Classname $yourObject)
You have to call the helhum function with the argument:
$this->setTypeConverterConfigurationForImageUpload('yourObject');
As a small hint for later problems: In the setTypeConverterConfigurationForImageUpload function you should register your own file attributes if they are not named image and/or imageCollection.0 like in the example.

GetExportedValues<MyType> returns nothing, I can see the parts

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.

Enterprise Library Logging tracelistener extension issue with resolving ILogFormatter

I have been sitting with a problem for quite a while now and I just can't seem to find what I'm missing.
I have written a custom trace listener component for Enterprise Library 5.0 for the Logging application block which works but the configured ILogFormatter just won't resolve and so I always end up with the basic string text when it gets handled by my component.
I saw in the enterprise library source code that they use the "Container.ResolvedIfNotNull()" method. It doesn't seem to work for me. I need it to write out a custom formatted string for my component to use. You know, not just the message but the timestamp, machinename, threadId, etc.
Does anyone have any ideas on how to fix this?
Thanks in advance.
Like I've mentioned on this site: http://entlib.codeplex.com/discussions/261749
When you create your CreationExpression in the TraceListener data class make sure you have a flat constructor definition. To put it in other words, don't return:
() => new MyTraceListener(new TraceListenerConfig(..., Container.ResolvedIfNotNull<ILogFormatter>(), ...));
just have it in the constructor of the MyTraceListener:
() => new MyTraceListener(..., Container.ResolvedIfNotNull<ILogFormatter>(), ...);

How to fix issues when MSCRM Plugin Registration fails

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.
