Closed Unassigned: Get Unhandled exception in TaskEditDialog for v1 if try to change "configure for" [12339]

Hello,

If I set forceV1=true on V2 systems and try to change a task via TaskEditDialog I catch an exception.
There is ability to change version via dialog and the exception occurs if you try to change it.
(Dialog disable this option for V1 system)

```
