[TYPO3-mvc] Putting together a object for updateAction, from ExtJs/json

[dennis ahrens]

Hi Dmitri,

the data comes in one POST/GET parameter and is encoded in json. The
"problem" is the loacation (in the code) where to apply the data to
the php-object. Of course it feels much better when the action
receives a modified object where the json data is applied instead of
the array containing the changes.
For fluid templates the magic is done when initializing the controller
and it's action. I think  the implementation should be done at the
same location.
Can anyone give a cleaner view for this scenario?

regards
Dennis
