[antlr-interest] hasPredicateBlockedByAction ???

[Avid Trober]

Hi,

does anybody know how to determine the source of an error such as this?
the wiki says convert the grammar to v3; it is a v3 grammar.

Thanks.

I found one hit in the wiki that states the grammar is a v2.x and needs to be reformatted to v3.  I think the grammar is v3, its the  ECMAScript example on the ANTLR grammars page:http://www.antlr.org/grammar/1206736738015/JavaScript.g

Ben
