Hello everybody,

this must be a stupid small thing, but when I add an own TypeComputer in the domainmodel example like

public class DomainmodelRuntimeModule extends AbstractDomainmodelRuntimeModule {
	
	@Override
	public Class<? extends ITypeComputer> bindITypeComputer() {
		return PidoTypeComputer.class;
	}
	
	public Class<? extends IResourceStorageFacade> bindResourceStorageFacade() {
		return BatchLinkableResourceStorageFacade.class;
	}
}

I get the following error when running the Eclipse via "Run as":

!MESSAGE org.eclipse.xtext.example.domainmodel.ui.internal.DomainmodelActivator  - Guice creation errors:

1) No implementation for org.eclipse.xtext.xbase.XExpression was bound.

  at org.eclipse.xtext.service.MethodBasedModule.configure(MethodBasedModule.java:57)

2 errors

I don't thinki that a binding of all method parameter is needed, so why is Guice doing that???

Thanks,
Ingo

How does your type computer impl look like?

It looks like this:

public class PidoTypeComputer extends XbaseWithAnnotationsTypeComputer {

	@Inject
//	private IXtendJvmAssociations associations;

	@Override
	public void computeTypes(XExpression expression, ITypeComputationState state) {
		if (expression instanceof XI18NLiteral) {
			_computeTypes((XI18NLiteral) expression, state);
		} else {
			super.computeTypes(expression, state);
		}
	}

	protected void _computeTypes(XI18NLiteral anonymousClass, ITypeComputationState state) {
		LightweightTypeReference string = getRawTypeForName(String.class, state);
		state.acceptActualType(string);
	}
}
