[antlr-interest] ANTLR 3.4: missing parameter in the method generated for a syntactic predicate for a rule with a parameter

[Francis ANDRE]

Hi

The generation of the method for the syntactic predicate of a rule with a 
parameter is missing the parameter in its signature, which leads to a compile 
error. I did not find out a way to fix this problem in the code base of antlr.

I would appreciate that someone looks at it and eventually fix this problem 
because I am stuck

Here the CMinus grammar modified with the variable rule having a parameter and 
conditioned by a syntactic predicate:
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------
program
scope {
   List globals;
   List functions;
}
@init {
   $program::globals = new ArrayList();
   $program::functions = new ArrayList();
}
     : _declaration[2]_+
         -> program(globals={$program::globals},functions={$program::functions})
     ;

declaration[int i]
     : _(variable[i])=>variable[i]_ {$program::globals.add($variable.st);}
     |   f=function {$program::functions.add($f.st);}
     ;


_variable[int i]_
     :   type declarator ';'
         -> {$function.size()>0 && $function::name==null}?
            globalVariable(type={$type.st},name={$declarator.st})
         -> variable(type={$type.st},name={$declarator.st})
     ;


Here the generated code
---------------------------------
     // $ANTLR start synpred1_CMinus
     public final void synpred1_CMinus_fragment() throws RecognitionException {
         // 
C:\\Users\\FrancisANDRE\\workspace\\zAntlr3\\src\\cminus\\CMinus.g:39:9: ( 
variable[i] )
         // 
C:\\Users\\FrancisANDRE\\workspace\\zAntlr3\\src\\cminus\\CMinus.g:39:10: 
variable[i]
         {
         pushFollow(FOLLOW_variable_in_synpred1_CMinus101);
         variable(i); _// <== i cannot be resolved to a variable    
CMinusParser.java    /zAntlr3/src/cminus line 1744    Java Problem_


         state._fsp--;
         if (state.failed) return ;

         }

     }
     // $ANTLR end synpred1_CMinus
