Description

If a hidden field has a blanc input "" , it fails with the following stackstrace (my Hidden component is just a copy of the orginal of 5.1.0.5)

The reason is that there is no nullfieldstrategie assigned to a hidden field as opposed to text fields. The attached patch adds such a strategie.
