Check all your code in the handler for OnClickSubmit. Seems like you are accessing an object that is not there. Check for null and add debug logging to see just how many lines of your code in that handler that you can pass. Could it be that you are accessing something in the UI, before it has been rendered? That is a common mistake. To think that the panel is available for your code to get values before it is rendered?

Basically you have a bug in your ISO script and you don't have any try-catch code so Smart Office crashed. Or it will not crash because we have a default handler that detects the crash and tries to survive the bad code... If such a crash happens on a background thread then the entire client will actually crash so be sure to have try-catch and proper error handling in all scripts.

It would have been useful to see the actual log entry about the crash.

"Object Required" means that you are accessing some method or property on an object but the object is null. You did not give enough information for any more detailed answer than this, I'm afraid.

[View:/cfs-file/__key/communityserver-discussions-components-files/111/Error-Log.log:320:240]Thank you for the reply.

Idea about "Object Required " error is quite clear,but still not getting exactly which Object is null in this case.

Attached the Error Log for more information.

Thank you so much for your help.

I checked the code and found the lines which was causing the error.

Issue has been resolved now.
