This JIRA basically says it's a bug that Templates cannot be expanded unless a value is given for each template-key.

E.G. Smurf( name == "@{smurfName}", colour=="@{smurfColour}" ) won't be included in the generated DRL unless a value for "smurfName" and "smurfColour" is given.

IMO, I'd agree - it's a painful limitation, however thought I'd ask if anybody knows of any history as to why it might have been implemented this way before I stamp over what might be considered as "correct behavior"?

Obviously, in my example, Smurfs are always blue ;)
