[antlr-interest] Strange problem with syntactic predicates

[Ali Salehi]

Hi all,
 I have a very simple grammar [only two lines] below (ErrGenerator.g) :

grammar ErrGenerator;
start : ('namely')=>'namely' | ('name')=>'name' | 'name';

Whenever i want to test this grammar using the antlr in the interpreter
[GUI],
I get the FailedPredicateException(start,{synpred1}?) error for a simple
input of 'namely' [without quotes].

As this grammar is tremendously simple, I appreciate if someone could help
me on this.

Best regards,
AliS

PS
- I know I can write this grammar in much simpler form. Actually my
main .g file is much
bigger [~200 lines] and the above sample
grammar generates the error I'm facing in my main .g file.
