List Edit on related lists does not work if the first related list is hidden with 'Omit if empty' - Known Error

List Edit on related lists does not work if the first related list is hidden with 'Omit if empty' Description The list edit on related lists is no longer possible if the first related list tab does not show (omit if empty).

Steps to Reproduce

1. Open any Problem form. 2. Ensure the two related lists shown OOB, Incidents and Problem Tasks, are both empty. 3. Create a Problem Task for that PRB record. 4. Once the task shows in the related list, try to edit the fields in the related list. Notice it works fine. 5. Set the first related list, Incidents, to the value 'Omit if empty' (customize list control). 6. Reload the Problem form and try to edit the problem task related list fields. Notice you get no response.

Workaround After carefully considering the severity and frequency of the issue, and the cost and risk of attempting a fix, it has been decided to not address this issue in any current or near future releases. We do not make this decision lightly, and we apologise for any inconvenience.

This issue only occurs on List v3 which is no longer supported. The workaround for List v2 is the following:

1. Uncheck 'Omit if empty' in the List Control of Related List.

2. Create a onLoad Client Script using 'g_form.hideRelatedList()' to hide the Related List.
