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
