Sebastian Hennebrueder commented on TAP5-832:
---------------------------------------------
I looked through the existing tests and I am not sure how to build the test in
the most efficient manner.
Shall I use a PageTester
http://tapestry.apache.org/tapestry5/guide/unit-testing-pages.html or
is there a simplere way to simulate a form submit?

> Project: Tapestry 5
> Issue Type: Bug
> Components: tapestry-core
> Affects Versions: 5.2.0.0, 5.1.0.5
> Reporter: Sebastian Hennebrueder
> Attachments: Hidden.patch
>
>
> 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.
