Binding controls to null-valued bean properties [message #723576]

I was wondering if it is possible to bind controls to beans that have only been initialized, so that their properties are all nulls (for example, null Strings).

When I try to do it right now, I get an NPE because the JFace tries to load the data from the model to the target widget. Is there a way to make it not do that, or at least handle nulls gracefully?

This is useful to me because I have a "New Order" window, and I use the same one to edit an existing order. In the new state, I just want to pass a newly instanitated Order object (it's a Hibernate persistent class that's also a bean) to the view the same way I pass a fully instantiated one for editing.
