So the first problem I see is that at startup, none of the Combo's are
disabled. That is because Combo disabling is handled in
commitProperties and you are changing the enabled after
super.commitProperties. That is fixed by moving super.commitProperties:
override protected function commitProperties():void {
if (_oItem) {
var bDisabled:Boolean = !_oItem.disabledFlag
this.enabled = bDisabled;
trace("commitProperties - value:" + _oItem.value
+ ", DISABLED=" + (this.enabled == false));
}
super.commitProperties();
}//commitProperties
The next problem is that clicking a checkbox doesn't update. Editing is
session based and won't update the DP on click, but later when focus
leaves the editor. Normally you put in a click/change event on the
checkbox renderer and call itemUpdated on that event.

The CBO set data and commitProperties overrides are getting called
correctly by the framework whenever I click the checkbox in the other
column, and the CBO.enabled property is being set correctly, per the
trace.
If you have time and inclination, take a look at my test case the other
post.
Thanks, Tracy

What is supposed to cause your ComboBox to revalidate then? I could
certainly be wrong but its worth a shot.
