[TYPO3-project-formidable] using $this->oMajixEvent->getParam('value') inside SEARCHFORM

[Thomas Meixner]

Hello list,

I've been stuck on this for quite a while. I want to use the "nested 
list example" inside a renderlet:Searchform but I cannot get the current 
selected value via $this->oMajixEvent->getParam('value').

I think the problem is that my Listbox is already nested inside the 
searchform, in the example below $sRub is just empty.

<renderlet:SEARCHFORM name="detailedSearch">
<datasource use="jobs" />
<childs>


<renderlet:LISTBOX name="mrc" label="MRC">
	<search onfields="tx_dmmjobcontrol_job.mrc" />
	<onchange runat="ajax" params="mrc">
	   <userobj>
		 <php><![CDATA[/*<?php*/
//oDataHandler doesn't seem to work with ajax
//$sRub = $this->oDataHandler->_getThisFormData("mrc");
$sRub = $this->oMajixEvent->getParam('mrc');
$this->aORenderlets['detailedSearch']->aChilds['mrc']->setValue($sRub);
$aItems = 
$this->aORenderlets['detailedSearch']->aChilds['city']->_getItems();

return 
$this->aORenderlets['detailedSearch']->aChilds['city']->majixReplaceData($aItems);
			/*?>*/]]></php>
		   </userobj>
		</onchange>
		<data>
		   <userobj>
			<php><![CDATA[
return $GLOBALS["TYPO3_DB"]->exec_SELECTgetRows("uid as value, name as
caption", "tx_dmmjobcontrol_mrc", "","name","");
			]]></php>
		   </userobj>
		</data>
</renderlet:LISTBOX>

...

</childs>
</renderlet:SEARCHFORM>



What would be the right syntax using Ajax?
Can I maybe use just server events since I can nest them with the 
aORenderlets?


Thanks for looking,
