Problem with cross reference [message #1706162]

Hi,

I've got a problem with cross referencing which I don't understand.

This grammar does work:

Mosa:
	name=STRING
        mobeReferences+=[mobe::Mobe]*
;

While this does not:

Mosa:
	name=STRING
	steps+=Step*
;

Step:
	mobeReference=[mobe::Mobe]
;

The file I use to test looks like this:

"Name"
step1

The error says:

Couldn't resolve reference to Mobe 'step1'.

The mobe grammer looks like this:

Mobe:
	'name' name=STRING
;

What am I missing? Shouldn't this end up doing the same?
Thanks.

@christian You are right, Florian should use the STRING rule as the concrete syntax for the cross reference. But it does not explain why example 1 works for him and example 2 doesn't.

@florian I tried your example and both grammars work for me. Are you sure there is nothing else causing the problem? Make sure your test setup for both cases is exactly the same.
