Error "g_form is undefined" in UI Page client script

[ramireddy]

Hi All,

I am trying to implement the functionality, "When a user clicks on a image in a UI page, its needs to display a dialog box asking for comments, On providing comments, its needs to invoke certain action." something like call back from GlideDialogWindow, not form.

To display comments page, I created another UI page and calling that UI page by using GlideDialogWindow. But in the comments page, when the user clicks on "OK" button, I am getting the error, "g_form is undefined". I can see in wiki that it's a global object.

Can you please help me here, with the solution to this issue.

I am trying an example mentioned in bottom of below page. In the client script validation method, I am getting this error.
