Exception with ResourceSetBasedResourceDescriptions occurs [message #655755]

I parse my model and saves changed information this way:

ResourceSet rs = new XtextResourceSet();
XtextResource res = null;
		
try {
res = (XtextResource) rs.getResource(URI.createFileURI("myfile"), true);
}
catch(RuntimeException rte) {...}
...
res.save(null);

Afterthere every time I open the affected file (which i saved before) I get following Exception:

2011-02-22 15:46:01,359 [Worker-11] ERROR org.eclipse.xtext.builder.impl.XtextBuilder - Passed org.eclipse.xtext.resource.IResourceDescriptions not of type org.eclipse.xtext.resource.impl.ResourceSetBasedResourceDescriptions

I found out that context param is instance of CurrentDescriptions and not ResourceSetBasedResourceDescriptions as required:

public IAllContainersState get(IResourceDescriptions context) {
if (context instanceof ResourceSetBasedResourceDescriptions) {..return..}
throw new IllegalStateException...
}

How can I avoid this exception?

I suspect you execute your code from within an Eclipse aware JVM. In
this case, you should rather use the IResourceSetProvider to instantiate
your XtextResourceSet. Note that it requires to hand in an IProject,
which is necessary to derive the org.eclipse.xtext.resource.IContainer
information for the index.

The ResourceSetBasedDescriptions should be used if you want to define
your universe of visible elements by loading resources into a resource
set, which is the default in the non Eclipse scenario.

so you mean i should try something like:

MyDsl.doSetup();
XtextResourceSetProvider xrstp = new XtextResourceSetProvider();
ResourceSet rs = xrstp.get(myProject);

in this case Provider<XtextResourceSet> resourceSetProvider is always null?

Please refer to the documentation on google guice for details but your
code should basically look like this:

@Inject
XtextResourceSetProvider provider;

void doStuff(IProject p) {
rs = provider.get(p);
..
}

Sebastian

Yes, this was exact my question.
The provider is always null, if i invoke doStuff-function. I don't know exactly how and where i should bind it not to get empty object.

Dependency injection just works on instances that are themselves created
using DI. If you instantiate your element with an explicit constructor
call, no fields will be injected.

Hello,
I have the same error when trying to convert a XMI resource (Containing a EMF model) into a Xtext resource. But in my case, I'm already using Guice's DI mechanism.
Here is my code:

Injector injector = new MyDslStandaloneSetup().createInjectorAndDoEMFRegistration();
XtextResourceSet outResourceSet = injector.getInstance(XtextResourceSet.class);
[...]
Resource outResource = outResourceSet.createResource(outResourceURI);
outResource.getContents().addAll(inContent);
outResource.save(null);

And I'm getting the same Exception

java.lang.IllegalStateException: Passed org.eclipse.xtext.builder.clustering.CurrentDescriptions not of type org.eclipse.xtext.resource.impl.ResourceSetBasedResourceDescriptions

What am I doing wrong ?

I think I found the problem.
It was because I'm using MyDSLStandaloneSetup in an AbstractHandler (in a Bundle).
Replacing

Injector injector = new MyDslStandaloneSetup().createInjectorAndDoEMFRegistration();

Injector injector = Guice.createInjector(new MyDslRuntimeModule());

solved the issue.
I found some clues here : https://bugs.eclipse.org/bugs/show_bug.cgi?format=multiple&id=326024
