Find references across languages? [message #1108124]

Hi,

Playing around with Ctrl-Shift-G (Find References) many expected references were missing from the search result. Looking closer it seemed that all references from another DSL into the current file were missing.

Is this supposed to work?
Is there s.t. I need to configure for this to work?

Some of these references are directly resolved via imports, others are handled by custom code in my scope provider. Should search find all these?

thanks,
Stephan

PS: This is in Xtext 2.4.3

All references, also those across languages, should appear. Are you
using Xbase?

References are collected during indexing. Did you have any build
problems? Did you disable the automatic build? Maybe a clean build
solves the problem. Do all projects have the Xtext nature?

I've also seen people deactivating the BuilderIntegrationFragment in
their languages' workflows. That also disables indexing.

no to all.

the good news: right now I see all expected search results, the bad news: I can only guess that some intermediate clean build fixed this.

Knowing that it should work, I'll keep an eye on it, and if the problem comes back, I'll try a clean build to fix.

Thanks,
Stephan

PS: on a mildly related note: trying to associate icons to search results, I tried all steps mentioned in the help document, but only this approach helped for the cross-language scenario:

	@Override
	public Object image(IReferenceDescription referenceDescription) {
		EReference ref = referenceDescription.getEReference();
		if (ref == MyPackage.eINSTANCE.getMyElem_SomeFeature())
			return "TgtElem.gif";
		// more like this ...
		return super.image(referenceDescription);
	}

Is that indicating some malfunctioning, or could the help document be outdated in this respect?

Also the label text is constantly "<unnamed>" where the help document mentions that the indexed name be used by default.

Within one of the involved languages things appear to work, mh..
