Scope method not execute? [message #991272]

I've got this IScope method:

        IScope scope_Assignment(AssignmentOrFBCall a, EReference ref){
		System.out.println(a.toString());
		return IScope.NULLSCOPE;
	}

but it doesn't produce any results. Nothing in output with println and content assistant does not change. So I thought it hasn't be executed, but if I try to add a breakpoint, it will be crossed.

So, where is the problem?

Grammar rule is this:

AssignmentOrFBCall:
	(((variable=[VariableDefinition]) |
	((variableArray=[ArrayDefinition]'['index=ExpressionIndex']')('.'internalVariable=InternalRecursive)?) | 
	(variableStructOrFB=[VariableDefinition]'.')(internalVariable=InternalRecursive))
	((':='expression=Expression)|('('(parameter=FBParameter | ')'))))
;

Hi Xtext creates objects lazy so the context may be a parent. Use a
parent as context or try an unassigned action

Hi,

the name of the scope method must be correct as well. Debug the getPredicate method in AbstractDeclarativeScopeProvider to see the "expected" method name.

Ok,
I'll try it.

Very thank you.
