[TYPO3-formidable] access parent PluginObject in ajax list

[Jérôme Schneider]

Hi All,
I use another option usually, and it's based on the fact that in the 
ajax context, the only objects that are maintained after page load and 
across successive events are the codebehind objects.

To declare a PHP codebehind object, apply these instructions:
http://formidable.typo3.ug/features/codebehind-syntax.html

If an init() method is declared in your CB class, the system will call 
it only one time, when the object is forged during page generation.
This gives you an opportunity to store locally in you CB objects 
variables that belong to the parent plugin for instance.

An example:
class mycodebehind {
   function init() {
     $this->aFlexConf = $this->oForm->oParent->cObj->data["pi_flexform"];
   }

   function btnHello_click() {
     // this will work :)
     return $this->majixDebug($this->aFlexConf);
   }
}


Now if what you need is a method, you'll have to externalize your needed 
parent method in an autonomous library and load it in both the parent 
and your codebehind, to be able to call it from the two contexts 
(pageload and ajax).


NOTE: depending on you version you may also define another magic method 
named initAjax() that is called when the object is unhibernated from 
session.

I hope this will clarify a bit.

Best regards,
Jérôme Schneider
