[antlr-interest] unexpected token:

[skfcz]

Hello,

I'd like to simple, but nested list like
 {{0 1 2}{3 4 5}{6 7 8}} into nested java list.

The main work is done something like this in the lexer
OPENBRACE: ('{')
     {	
	// add a new list to the stack to be filled by later
	// Integer, Real, Boolean and Null calls
	List currentList = new ArrayList();
	stack.push( currentList );
	} ;
CLOSEBRACE: ('}')
     {
       // add the contents of the current list to the previous one
       // in case stack.size() > 1
       if ( stack.size() > 1 ) {
	 Object currentList = stack.pop();
	 List previousList = (List) stack.peek();
	 previousList.add( currentList );
       }
     } ;

and works pretty well. The parser looks like this:

simpleList : 
	OPENBRACE ( INTEGER | REAL | BOOLEAN | NULL | SPACE )+ CLOSEBRACE
        {
	  //InlineList.parserLog.info("found simpleList " );
 	} ;	
nestedList :
 	OPENBRACE ( simpleList | SPACE )+ CLOSEBRACE
        {
	  InlineList.parserLog.info("found nestedList " );
 	} ;		

inlineList :
 	( nestedList | simpleList )+ 
         {
	   //InlineList.parserLog.debug("found inlineList " );
	 } ;	

Everything works as expected, but I get an additional warning
line 1:2: unexpected token: 0 
parsing the strings, in this case {0 1 2 3 null}.

How could I get rid off this warning ?

Thanks, Carsten
