[TYPO3-mvc] Initializing extbase with bootstrap for eID mechanism

[Domi]

Hi Frank,

not sure if this is what you are looking for, but my ajax/json calls 
works like a charm:

TS:
ajax = PAGE
ajax {
   typeNum = 77769
   10 < tt_content.list.20.myext_frontend
   10.persistence.storagePid = {$plugin.tx_intranet.persistence.storagePid}

   config {
    disableAllHeaderCode = 1
    additionalHeaders = Content-type:application/json
    xhtml_cleaning = 0
    admPanel = 0
   }
}

Now you just need to register inside the controller the specific action 
and thats it actually.

Cheers Dominic
