Here is the snippet of code that I'm using :
AgendaFilter filter = (AgendaFilter) new RuleNameEndsWithAgendaFilter("Test");
// Gives a compile time error if I don't cast it.
// Run the rules
int numOfRulesFired = stateFulKnowledgeSession.fireAllRules(filter);
This spits out a runtime Exception :
java.lang.ClassCastException: org.drools.base.RuleNameEndsWithAgendaFilter cannot be cast to org.drools.runtime.rule.AgendaFilter
Please let me know If I'm missing out something here.
Thanks,
Ashwin
Looks like you have the wrong AgendaFilter. I checked the latest Drools codes and org.drools.runtime.rule.AgendaFilter no longer exists or it is renamed to something better.
Use org.drools.spi.AgendaFilter and it works.

How to fix this?
IntentIntegrator test = new IntentIntegrator.forFragment(this);
forFragment, forforSupportFragment too
Cannot resolve symbol
Your invocation is wrong. Should be
IntentIntegrator test = new IntentIntegrator().forFragment(this);
Notice the first parentheses.
or
IntentIntegrator test = IntentIntegrator.forFragment(this);
Sorry but I used the older version, so I am not sure how the invocation looks right now.
I am unable to fire an "onchange" event in mshtml. Can you please tell me what I am doing wrong here.
HTMLSelectElement element = (HTMLSelectElement)this.HTMLDocument.all.item(controlId, 0);
IHTMLElement e = element as IHTMLElement;
IHTMLDocument4 doc = e.document as IHTMLDocument4;
object dummy = null;
object eventObj = doc.CreateEventObject(ref dummy);
HTMLSelectElementClass se = element as HTMLSelectElementClass;
se.FireEvent("onchange", ref eventObj);
I am getting variable "se" as null. I got this piece of code from another link http://www.itwriting.com/phorum/read.php?3,1507
Can anyone help me with this.
Thanks,
Sam
Runtime Callable Wrapper objects generated by COM calls like HTMLDocument.all.item can translate interface casting to QueryInterface calls. But the RCW does not know how to convert to a managed class like HTMLSelectElementClass, thus it returns null.
Instead of casting to HTMLSelectElementClass, cast to IHTMLElement3 to call fireEvent.
By the way, your code does not work in IE11 mode as document.all is deprecated. Use IHTMLDocument3::getElementById instead.
I had tried all those which Sheng mentioned but didn't work.
This issue was solved by injecting javascript code for "onchange" and executing it. It worked.
I would like to require the webpack.config in karma.conf to reduce duplication. Somehow it is not working and some errors are being thrown.
Module not found: Error: a dependency to an entry point is not allowed
ERROR [karma]: Uncaught ReferenceError: webpackJsonp is not defined
the way webpack.config is required in karma.conf
var webpackConfig = require('./webpack.config');
webpackConfig.devtool = 'inline-source-map';
webpackConfig.plugins.push(new RewirePlugin());
The entry and output property of the webpack.config are not needed in karma.conf, that might be messing with the setup. How can I get rid of it?
I have tried: webpackConfig.entry = {}; which didn't succeed.
The problem could also be something else?
Would be very nice if you could point to an existing example or correct my mistake!
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'm trying to call a webservice from the play framework, and I think I'm doing it wrong. I have an example call to http://www.myweather2.com/developer/forecast.ashx?uac=eDKGlpcBQN&query=52.6%2C-4.4&output=xml
A snippet from what I'm trying from the playframework is the following:
val response = WS.url("http://www.myweather2.com/developer/forecast.ashx?uac=eDKGlpcBQN&query=52.6%2C-4.4&output=xml").get.get()
val body = response.getBody
When I call this, the body consists of "useraccount does not exist". When I just put this url in a browser, I get the response I'm looking for. What am I doing wrong here?
For some reason, I was getting WS from the wrong import. When I fixed the imports to import play.api.libs.ws.WS, it worked. I'm still amazed it worked halfway with the wrong import
Don't know about "useraccount does not exist" but this seems to work:
val promise = WS.url("http://www.myweather2.com/developer/forecast.ashx?uac=eDKGlpcBQN&query=52.6%2C-4.4&output=xml").get()
val body = promise.value.get.body
Edit: Removed the space.
Also make sure your editor is not inserting a \n or \r after ?
I know this is old, but I just solved this problem while trying to do the same thing - getting the same results.
GET variables must be passed with WS.url("http://...").setQueryParameter(key, value)
Example:
val promise = WS.url("http://www.myweather2.com/developer/forecast.ashx").setQueryParameter("uac", "eDKGlpcBQN").setQueryParameter("query", "52.6%2C-4.4").setQueryParameter("output", "xml").get()
Annoying, but a relatively simple fix.
