[antlr-interest] Problem with remote debugging

Hello,

I have a problem getting remote debugging working.
I start the generated C# parser. It pauses at construction of the SclParser
and waits till I have connected ANTLRWorks with "Debug remote. The debugger
displays "Break on Commence" and when parsing continues with executing
sclParser.prog() the debugger never stops at any breakpoint or so. I see
that the grammer is correct, because of the console output. I also can't see
anything in the "Input"-window although I have enabled "Show Input Tokens".
So currently debugging is not possible. Can anybody help me?


I have the following configuration:
- ANTLR .NET runtime 3.1.1
- ANTLRWorks 1.3.1

My grammer:

grammar Scl;
options 
{
	language = 'CSharp2'; 
} 
prog	:	stat+  ;
stat	:	expr NEWLINE
	|	ID '=' expr NEWLINE
	|	NEWLINE
	;	
expr	:	multExpr (('+' | '-') multExpr)*
	;	
multExpr 
	:	atom ('*' atom)*
	;	
atom	:	INT { Console.WriteLine("INT"); }
	|	ID { Console.WriteLine("ID"); }
	| 	'(' expr ')' { Console.WriteLine("expr"); }
	;	
ID 	:	('a'..'z' | 'A'..'Z')+ ;
INT 	:	'0'..'9'+ ;
NEWLINE :	'\r'? '\n' ;
WS 	:	(' ' | '\t' | '\n' | '\r')+ ;


My test-driver:

            ANTLRStringStream inputStream = new
ANTLRStringStream("(2+3)*5\n");
            SclLexer sclLexer = new SclLexer(inputStream);
            CommonTokenStream tokenStream = new CommonTokenStream(sclLexer);
            SclParser sclParser = new SclParser(tokenStream);
            sclParser.prog();

Thanks in advance,
Wolfgang
