The control will be updated while the application idles, or in the case of
menu items - when the menu is opened.
The enabled property should be set in the "onUpdate" event of the action.
If you want to force the target controls to update, you can call
TBasicActionLink.Update (this is done in Menus.pas for instance in
"TMenuItem.InitiateActions")
So if I understand your problem right, just write a handler for onUpdate (or
override TBasicAction.Update) that says
"Checked := <logical expression involving your Property Entry>"
And then the control will automatigically be updated at some random point in
the future.
It's a "pull" mechanism from the control's perspective rather than a "push"
from the action.
