I am trying to do something like:
ViewerSupport.bind(viewer,BeansObservables.observeList(Model Provider.getInstance(),
"items"),BeanProperties.values(new String[] { "itemName",
"price", "quantity", "subtotal" } ) );
But I get an exception "Realm cannot be null". However, this is a JFace
ViewPart that is called in a JFace tab. How in the world would I
instantiate a Realm in a ViewPart???

Are you running that code in the UI thread? In an Eclipse/RCP application
the UI thread has a default realm based on the SWT Display. All UI code in
the event loop generally does not need to worry about the Realm.
But if you have another thread, or if you are not using
Workbench#createAndRunWorkbench, then you have to deal with the
realm/synchronization issues yourself. See
http://wiki.eclipse.org/JFace_Data_Binding/FAQ#What_is_a_Rea lm.2C_and_do_I_need_to_care.3F
for more info.
