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

[dennis ahrens]

Hi Dmitri,

I don't know how to configure the JsonReader and the JsonWriter to
match the expected structure. If you're using a default store
configured with autoSave:true and writeAllFields: false the data is
placed automatically in an HTTP parameter called data. I think the
name 'data' is caused by the reader configuration, which wants it's
data in a json object property called data:

the configuration object for the Reader looks like this:

{totalProperty: 'total', successProperty: 'success', idProperty:
'uid', root: 'data', fields:[....]}

The Reader can interpret reponse data which looks like this:
{"message":"foo","total":0,"success":true,"data":[]}

When using the CRUD features shipped by extjs the described HTTP
request param named 'data' is send to the server.

regards
Dennis
