I have this error only when I use ID0 in my grammar
Have you any idea why this error occurs ? thanks in advance

The rule shadows the ID rule. Remove the 'terminal' keyword (i.e. make
it a parser rule) and it will work.

The error is a follow up error obfuscating the cause of the problem.
We need to make sure to present the cause of the problem. I've entered a
bugzilla : https://bugs.eclipse.org/bugs/show_bug.cgi?id=315723

Hi
i am facing the same issue now.but i don't have anything like duplication in my grammar.(i.e., something like id1 and id0) .

Is there any other possible reason for the error.

By the way when i build my RCP application everything is fine in my system.but when i try the product in another machine i cannot create or open file and it shows this exception

Any help would be appreciated

Thanks and Regards,
Anudeep.
