I can't see what you are doing wrong without seeing your grammar. Oh, you
removed it altogether and there is an issue somewhere in StringTemplate
where it does not see the default that I set up.
Just copy from this or the examples grammars in the examplse tar:
// Author: Jim Idle, Temporal Wave LLC, Feb 2008.
//
tree grammar tsqlwalker;
//
--------------------------------------------------------------------------
-----------------
//
--------------------------------------------------------------------------

// Grammar options
//
options
{
//
tokenVocab = tsql;
//
ASTLabelType = pANTLR3_BASE_TREE;
language = C;
}
