In Eclipse 3.4, there is a new class, 
org.eclipse.core.databinding.beans.PojoObservables, that supports 
creating observables on objects that do not fire property change events. 
The limitation, of course, is that the framework isn't notified if the 
underlying objects are changed directly - that's what the property 
change events provide. So if your model objects don't do that they can't 
tell the data binding framework when their properties have changed.

Hope this helps,
Eric
