The readonly or enabled property is not working when the form is not visible in front. The actual value of the property is set properly. I can verify the value using a dialog. But it has no effect on the form if the form is not in front.
what do you mean not at front?
if you do:
forms.xxxx.controller.readonly = true;
and then
forms.xxxx.controller.show()
then the form is not in readonly mode??
do you have an example?
