[stringtemplate-interest] Setting the default lexer on the common group loader

[ed ed]

Terence, 
You are a scholar and a gent!

For the record here is what I have now:
StringTemplateGroupLoader loader = new CommonGroupLoader(FOLDER, new ErrorListener() );
StringTemplateGroup.registerGroupLoader(loader);
StringTemplateGroup group = StringTemplateGroup.loadGroup("classgroup", DefaultTemplateLexer.class, new StringTemplateGroup("super") );
StringTemplate template = group.getInstanceOf("classGenerator");
template.setAttribute("config", "config" );
log.info(template.toString() );

Best,
Ed

Hi Ed,

can you try using the lexer argument on the constructor to the group? I think the problem is related to loading the templates before the appropriate lexer has  been set.
