[antlr-interest] Use of multimap in grammar file.

[Alfredo Perez J.]

Nevermind that previous post (accidentally doubled btw). My mind  after many
hours couldn't see an extra ; that was  there which caused the error.

Now I have a different quesiton if you mind.

I have some expression like this:

TRANSITION IDENTIFIER TO IDENTIFIER transFlags

Now what I want in this step is store IDENTIFIER.text from the left side and
IDENTIFIER.text from the right side, but how can I tell one from the other?
Tried something like this:

TRANSITION IDENTIFIER {Auxiliar = {$IDENTIFIER.text}} TO IDENTIFIER
transFlags

Auxiliar beign a String but I get the error: IDENTIFIER is a non-unique
reference.
I can't define some sort of "LeftIdentifier" because it's the same rule and
it won't be matched.

Any idea how can I differenciate these Identifiers?
