Php error in simple edit after submit

I keep getting a php error after submiting a page in simple edit. Anyone know what it means?

     PHP Notice
    Undefined variable: update_design_cascade

Can you turn the error file name and line numbers on for error message in System Config and then post the file and line number.


Sure.

This was you were meaning?

Thanks, that is what I was after.


There is a bug fix for this to be released in 3.16.1. The problem only occurs if you acquire locks to view the editing interface and then they are released before you press commit. If your locks are being re-acquired, you wont be getting this error.



The bug fix simply removes the PHP notice, but that notice is telling you that something else is wrong with your locking. We haven't been able to find a way to replicate the problem besides removing the locks manually while editing.



If you are seeing this error consistently, check your simple edit layouts to make sure the designs section is not displayed twice somewhere, and make sure the top frame appears in simple edit and is refreshing your locks.
