JDev 10.1.2 error?

Question

I'm receiving the following error in my UIX 10.1.2 application. Does anybody know what I've done wrong? It happens when my application navigates to a struts data-action.
500 Internal Server Error

Answer 1

Steve, I have tried to reproduce the problem, by starting new-from-scratch workspace. Everything worked fine except for one problem that is not related to this post but is in UIX Logout event and login-again problem
However, I did NOT get HTMLElement error even though I do not have BC4J HTML lib included in Model nor in ViewController.
I guess I will remain in dark until future release of JDev. We cannot afford to build our projects from scratch every time an issue like this arises. Even though we use CVS it might be impossible to track-down which code addition triggered an error (which may show-up in 'remote' area of application). So I guess I would have a request for enhancement. Is there a way to add optional but recommended notification in design time, which would notify (and possibly log) user what has been done (in the shadow) after certain (wizard) operation is performed? For example, if one would drag&drop a table on blank UIX form, JDEV would 'tell' user which files (if any) has been created and/or modified. Does this make sense?
Regards.
