Hi Ter,
Unfortunately, that doesn't seem to work either.
additiveExpression
: multiplicativeExpression (('+'|'-')^ multiplicativeExpression
{$additiveExpression.setType(Operator);})*
;
in the parser grammar produces
if ( state.backtracking==0 ) {
$additiveExpression.setType(Operator);
}
in the parser class.
(I'm using 3.1b in case this makes a difference.)
Cheers,
Dimitrios
