I doubt that this is the full solution.
If the nameField can be null here then it can perhaps be null in setName.

The underlying cause of the issue needs to be found.

One problem I notice is that the NamePanel ctor calls setName() which
can be overridden - that can cause issues because the object won't be
fully constructed until the ctor completes.
This is why init() is private.
The setName() code either needs to be duplicated in init(), or it
could be put into a private method called by the ctor and the public
setName.
