CompletionProposal.METHOD_REF fails - but KEYWORD succeeds - why? [message #31491]

I have a language where the only thing that is modeled is what is in each
source file.
The source files can call other methods from the runtime library which are
not modeled.
I just attempted to implement some automatic completion.
If my completion proposals are of the kind CompletionProposal.METHOD_REF -
they fail to be generated properly and are not listed on the screen.

I ran my language's editor through the debugger, and I found the problem
(but not why):

public LazyScriptCompletionProposal(CompletionProposal proposal,
ScriptContentAssistInvocationContext context) {Assert.isNotNull(proposal);
Assert.isNotNull(context);
Assert.isNotNull(context.getCoreContext()); // this line throws an
AssertionException
fInvocationContext = context;
fProposal = proposal;
}

Hi Chuck,

I have looked at the sources and I am not sure that this assert is
really needed so I have commented out it.

Regards,
Alex
