I have a callback panel inside a dialog's template. The panel has many child controls and one is a an updateable table where each tablecell holds an update panel. When the tablecell's callback panel is executed the callback_before_execute_handler function fires but the server side execute does not and what ever is happening it is causing the dialog closes. Does anyone have any insights?

I created a test application to simplify the troubleshooting. When the nested callback panel tries to execute I get the error EO944. Is this a valid error code or do I need to keep testing?
