this one looks overly complicated to me. Even though it's not exactly
ambiguous, I suggest to rewrite the rule to the simpler variant
PsetFieldArray: '[' fields+=PsetField (',' fields+=PsetField)* ']';
You used the same pattern for PsetFlags and StringArray. I'd rewrite
There are other issues, e.g. you use a boolean assignement
fieldArray?=PsetFieldArray which will pretty much discard the rhs of the
assignment. These deserve a clean-up, too.
I hope these tips help.
