I have a custom control that has a property I have defined.  I use the composite data a label which is on the custom control.  The label displays just fine but I wanted to use the value of the label on a control that is outside the control with the label and composite data.

 

But is returning null for the value of the label.   It seems like that composite data is being calculated every time the label value is accessed and the reference point for the calculation seems to be the control accessing the label value rather than the control where it is contained.

 

I plan to use scope variables instead but is there any way I can make composite data work?
