disable edit if not null

Hi,

i'm searching a way to disable change dbjoin value in edit form, but only if value is setting.
If value is null, user can change it.

Thanks

Hmmm. I seem to recall adding a 'disable / enable' option to the JS events on elements a while back. I think you could probably do it with a 'load' event, that tests something like > 0, and disables.
