[TYPO3-mvc] Bug in FormHandling with checkboxes

[Sebastian Kurfürst]

Hey,

Or output the following code:
<input type="hidden" name="myProperty" value="0" />
<input type="checkbox" name="myProperty" value="1" />

as the latter one overrides the first one, this should work.

In the multiselect-box case: Is it really unset if no value is sent?
Hmmm - would not really expect this to happen. Maybe we need the same
trick there.

As the data mapper supports partial mappings, I am not sure if variant
b) works. The mapping takes place in Property_Mapper.

Greets,
