[antlr-interest] Newbie to ANTLR: Child node not found

[Jean Bovet]

That's because ANTLRWorks does not find some token in the AST. Can be  
either a bug in ANTLRWorks or a problem interacting with ANTLR. Can  
you send me the grammar file and the step needed to reproduce the  
issue (at my e-mail jean_bovet at mac.com)?

Thanks a lot!

Jean
