Description

Was fine in 5.1.0.5, discovered when upgrading to 5.2.5.

Using a BeanEditForm to edit an object: onPrepare() is being called twice during the render phase, and then the object found in onPrepare() disappears!

Yet, when you replace BeanEditForm with a Form around a BeanEditor, everything works correctly: onPrepare() is called once during the render phase and the object doesn't disappear:

You can see the java code is almost identical in the two examples but the result is different.
