Description

After updated from 1.4.8 to 1.4.14 I got this bug.

The problem is with nested property models where the "top" model has a null model object that is bound to a TextField. You get a NPE when the page is rendered. There is a quick workaround by overriding getOjbectClass() on the property model.

I provide a running example of the problem.
