[antlr-interest] Root note of tree doesn't have the index attribute?

[Bernardo Elayda]

Hi,

I'm having trouble with the following in a tree grammar:


myrule : ^(a='=' b=NODE c=NODE) -> mytemplate(mya={$a.index},
myb={$b.text},myc={$c.text}) ;


When I compile the above rule and compile the resulting java file, I get an
error that says it cannot find the method getTokenIndex for 'a'.  That
doesn't make sense to me.  Isn't the root node labeled as 'a' above just a
token?  If I change the above template to use $a.text, that works.

tia,
Bernardo
