Thanks to all.
Method 2 is working and I avoided a design mistake....
Binding question... are these pass by reference or by value when I use
this method?

1. parent() does not return a useful value in the constructor.
2. What you are doing is not the WO way. Pass theHotemItem to the
children
in a binding. This works better and reduced the coupling between
components.

I have several components that are inserted in another component via
the 'Custom WebObject' menu option in WOBuilder.
In the embedded components I have the following code in the
constructor:
theParentContainer = (RVHotelDetailMain)parent();
When I bind strings in this format:
theParentContainer.theHotelItem.hotelName
It comes back with no value...
If I do println on the variable from the parent component, it prints
the value:
DEBUG: Hotel: Bellagio
So... What am I doing wrong? Can't I access the parent as I did?
Thanks,
Hunter
