I setup a hom callback on a string field.
when i enter a value the callback is invoked.
when i delete the field, and hit enter the callback is invoked.
when i delete the field, and change focus the callback is invoked.
* when i RMB on the parameter (with data) and revert to defaults
(the empty string), the callback is NOT invoked.
has anyone else noticed this?
is it a bug or is there a reason for this behavior?
