Can you please explain why I get ambiguity between the edit and add alternatives in the Reuse parser rule in the grammar below. Everything works fine if the reuse assignment in the Link parser rule is just an optional (?), but if I change the cardinality to a multiple containment I get the error. I guess the parser doesn't take note of the diff keywords preceding the alternatives in Reuse- or is something else going on?? And also how do I fix it?? Would very muchprefer to do it with as little change to the grammar as possible :)
The arrow did the trick :D Thanks again! I'll try out antrlworks as well. I have tried to find documentation for the arrow in the Xtext grammar but with little luck. Can you refer me something, so I can read up on exactly whats happening here?
