I haven't worked with Templates, but I have seen this type of error when
compiling XLS to DRL.  The line and column numbers refer to the generated
DRL.  For spreadsheet debugging, I use code like this:

   DecisionTableConfiguration dtconf =
KnowledgeBuilderFactory.newDecisionTableConfiguration();
   dtconf.setInputType(DecisionTableInputType.XLS);
   String drlString = 
DecisionTableFactory.loadFromInputStream(ResourceFactory.newFileResource(path).getInputStream(),
dtconf);

and then look at the generated drlString at the line number cited in the
exception, to find the offending rule.
