Hello,
I am getting a weird behavior regarding the definitions of variables in my DSL. I use my DSL to define an input model, manipulate it and then serialize it as an output model.
My manipulation does not affect the variable declarations in any way, but I still some non-deterministic behavior. For example when my input is:
Some times the output is identical (which is good) but some times it will produce:
variables : {v}
variables : {k}
The relevant fragment of my grammar is:
Problem:
.....
('variables'':''{'
varDecl +=VariableDeclaration (',' varDecl +=VariableDeclaration)* '}'
)? &
.....
;
VariableDeclaration:
name =ID
;
Any ideas why I'm getting that behavior and/or how to fix it?

Could be a bug in the serializer with respect to unordered groups. It
would be great if you could strip it down to a minimal grammar that can
reproduce the bug.
