@method controlTextDidChange:

@updated 2003-08-01 UK: Changed to use data source's resourceOfType instead of directly messing with the resource list's enumerator.
|
|
@updated 2003-08-01 UK: Removed ID > 0 check -- negative IDs are allowed as well.<br/><small>Note from Nick: IIRC this was there as a workaround for another bug which prohibited negative IDs from being used. Not sure if that got fixed though :)</small>

@description Someone changed the control ID edit field. Check whether this is a unique ID and appropriately enable the "create" button.</p><p>Check "notification" against being nil, which is how we call it when we need to explicitly update the enabled state of the "create" button.
