[antlr-interest] antlrworks "NoViableAlt" exception

[Tom]

Hello,

I am new to ANTLR, using version 3.4.

Does anybody have an idea what could be causing the following discrepancy:

When I use the GUI interpreter on an input I get some console errors below.

Now I use the debugger on exactly the same input (copy/paste), the whole
thing works:  whole ASTree is built as I want it.

I have seen some posts about line ending characters and having to reset the
token stream, but this all doesn't seem to apply here, does it?


Thanks
Tom
