Hi
I have the following fragment in my grammar:
SeqConfig: op=ART_ID ((',' config_elements+=SeqConfigElement)* & (',' labref=LabRef)? )
(',' config_elements+=SeqConfigElement)* ;
The intent is that the DSL allows a single LabRef within a set of SeqConfigElement's
This input works (where NOP is a valid ART_ID and x=y is a valid SeqConfigElement:
NOP x=y, lab
But this does not
NOP x=y, lab, a=b
The error marker given in the generated editor is attached to the 'a' in a=b and appears to relate to a separate fragment of the grammar.
I have not yet tried to test my understanding of unordered groups and their interaction with other elements as I wanted to check with more experienced users where I might be going wrong.
Cheers and thanks for any help you can give,
- Dyson
