Chuck, after getting rid of some code in Awake I find I'm not getting the value of the sub-component binding back up to the parent, which was I believe my original problem a while back and the reason for the unusual code, in trying to be straightforward I now have:

In sub-component <MonthDayYear.java>

	 public NSTimestamp				mdyValue;

void rtrnDateFromPopups() {
gc.set( Calendar.YEAR, yearNum.intValue() )
...
mdyValue = new NSTimestamp( gc.getTime() );// this is correct at this point
pushValuesToParent(); // this seems to have no affect anymore

You should not have that.



}

public void takeValuesFromRequest( WORequest aRequest, WOContext aContext) {
// Assuming that you do want the data from the form...
super.takeValuesFromRequest(aRequest, aContext);

rtrnDateFromPopups(); }

In <EnterEvent.java> file in the Action method of the Submit:
editDate = (NSTimestamp)valueForBinding("mdyValue"); which returns null,
Yes, I would expect that to return null. That is getting the parent of EnterEvent's vlaue for mdyValue. Parent's don't ask their children for values.



// if I don't set <editDate> it has the original parent date.

Without the call to super.takeValues, I would expect that.




Bindings in <EnterEvent.wo> file:

EditMDY: MonthDayYear {
	mdyValue = editOldDate;
}
MonthDayYear: MonthDayYear {
	mdyValue = editDate;
}
