Hello,
I have an issue with the content assist failing to lookup for cross references when I use an EmbeddedEditor. It works well in a classic editor part.
After some hours of debugging it seems to be an issue with the ParserBasedContentAssistContextFactory.StatefulFactory.
The parser is dealing with EObject of my grammar but from two different instances of my grammar model which lead to parsing issue and failed to create a proper ContentAssistContext ( with a non null current model).
To be more precise when the doCreateContexts(
INode lastCompleteNode, INode currentNode,
String prefix, EObject previousModel,
Collection<FollowElement> followElements) is called :
the followElements are contained in a Grammar with instance id @1919ef, but the currentNode.getGrammarElement() is contained in a Grammar with another instance id. Thus, during the parsing, when doing all the switches with eobject comparaisons it fails.
This is happening with the content assist of the embedded editor only !
As I'm not friendly at all with injection stuff, I'm not able to understand how I can end up with this strange behavior.
Does someone can help me with this ?
Best regards
Romain

Hi Romain,
please make sure that you do not (and never) use the STandalone setup of
your language within Eclipse.

Sebastian

It solves the problem !
But it's really disturbing since the few doc I found on how to use the Embbed editor suggest to call the doSetup in the IEditedResourceProvider.
Thanks Sebastian, you save my day. But Ed is right, there should a protection or at least a bold line in documentation about this.
By the way, how can I access the injected fields such as the XTextResourceSetProvider ? I was directly calling the injector.getInstance(XTextResourceSetProvider.class) but it seems not to be the correct way.
