'Submit canceled due to a script error' when Simultaneous Update Alert is enabled and certain forms (such as search screens) are submitted

In the base system, the onSubmit client script, Simultaneous Update Alert, is enabled. A Javascript error occurs when you attempt to submit a form that does not have an "onnLoad_sys_updated_on" element defined. This blocks the operation. An example is a form that is loaded by search modules (using the Search Screen link type), such as incident_search.do, which does not load an actual record.

The error is displayed as glide.ui.js_error_notify. For admins, the error message is { onSubmit script error: TypeError: Cannot read property 'value' of null }... with the client script then being displayed.

Non-admins receive this simple message: Submit canceled due to a script error - please contact your System Administrator.

This issue occurs in Fuji and later releases.

1. Log in to a Fuji or later instance.
2. Ensure that the Simultaneous Update Alert client script is enabled (Active is checked).
   (/sys_script_client.do?sys_id=8ec642040a0a3c7400dc20a338770cc3)
3. Load a search screen page (for example, /incident_search.do.)
4. Populate one or more fields.
5. Click the Search button.
