Hi,
I have to following piece of grammar from wich I want to create a helpful 
errormessage:
Statecheck: OBJECT COMPERATOR statearg SEMI;
Statearg: PARAMREF | STATE;

Now if I give the input 
Motor =; 
Where Motor is recognized as OBJECT and = recognized as COMPERATOR I get an 
mismatched set exception. That's right, since a statearg is expected. 

Since this is a tree parser I get an unexpected node exception which is 
meaningless to our users. In the resulting exception neither the expecting nor 
the expecting set fields are set so I cannot create a helpful errormessage from 
it. I'd like to change the behaviour so that I can generate more helpful 
errormessages for this and other similar cases. 

I tried to specify a manual exception handler as explained in the ANTLR 
reference but the code isn't reached because recoverFromMismatchedToken catches 
and handles the error allready.

So what should I override to make things work and do it the right way?

Thx

Mit freundlichem Gruß
