Content assist context [message #59987]

Hello,

I have a question regarding the content assist context. In the generated
myDsl example, when I invoke the code completion after attr, the context
object is an instance of "Model" and not an instance of "Class" as I would
have expected.

class Name {
attr ...

}

public void completeAssignment(Assignment assignment, ContentAssistContext
contentAssistContext, ICompletionProposalAcceptor acceptor) {

//contentAssistContext.getCurrentModel() -> instanceof Model

}

However, I want to restrict the possible values based on the enclosing
class. My question is, how can I retrieve the instance of the enclosing
class?

Regards,

Sebastian

I filed a bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=283857

A workaround is to create a dummy rule for the attribute:

Attribute:
'attr' name=Name ':' type=[DataType] ';'?;

Name returns ecore::EString :
ID
;
