Sorry. Too lazy to cleanse I just left the package off. There is one, and a model._ import, too.
BTW, the snippet is responding, it just gives that snippet error and the edit doesn't bind the object's values to the form fields. The list and add abilities work just fine. That's what's so confusing. I can't see what's all that different from the JPADemo one except Derek's works and mine doesn't. Chas.
