If I have a grammar like this:

HLMModel	:
			'module' name=ID '(' (inputs+=ID (',' inputs+=ID)*)? ')' 
				('returns' '(' (outputs+=ID (',' outputs+=ID)*) ')')? '{'
				startup=Startup
				(states+=MyState)+
			'}' 
			;
			
Startup		:
			'startup' '{' nextState=[MyState] '}' ;

MyState :
		'state' name=ID '{' 'next' '=' nextState=[MyState] '}';

and an example like this:

module T() {
startup {a}
state a { next = b}
state b { next = a}
}

The cross-referencing to the State doesn't seem to work. However, if I change my HLMModel rule by commenting out the 'module' part, i.e.,

HLMModel	:
//			'module' name=ID '(' (inputs+=ID (',' inputs+=ID)*)? ')' 
//				('returns' '(' (outputs+=ID (',' outputs+=ID)*) ')')? '{'
				startup=Startup
				(states+=MyState)+
			'}' 
			;

Then, cross-referencing works OK. What am I doing wrong in the above grammar? Thank you for any ideas.

Have you got the SimpleNamesFragment or the QualifiedNamesFragment configured in your .mwe2 workflow file? I'm betting on the latter Wink

Hi,

Thank you for your help. I had enabled SimpleNamesFragment. By disabling that, and enabling QualifiedNamesFragment, it works nicely now!

Thanks.
