Which rule execute first client Scripts  or  UI  polices?

Hi

Ram2497

UI Policies execute after Client Scripts. If there is conflicting logic between a Client Script and a UI Policy, the UI Policy logic applies.

Client-based code:

"Client-based code that executes in the browser, using Ajax or running as Javascript, always executes before the form submission to the server."

This includes Client scripts and UI Policies.

First onLoad Client scripts, after that the first UI Policies kick in.

After that, the Client scripts and UI Policies that work onChange.

After that, the Client scripts that work onSubmit.
