Form Designer not editable

My form designer not able to edit (but can navigate to Id, Appearance, .NET, etc…) after I wrote a javascript function and save it.

Is anyone facing this before?

Hi GiapWeng,

Custom client-side JavaScript code must be executed in runtime mode only. To ensure this, enclose your JavaScript code with the following IF block:

if (typeof $selectedObject === "undefined") { // Place your code here }
