[TYPO3-project-formidable] datahandler:LISTER activelistable

[Jerome Schneider]

Hello Manuel,
The reason is that the activelistable feature has not been completely 
finished, due to lack of time. For the moment there's no integrated way 
to obtain data from renderlets repeated in a list. There's an ersatz of 
developement ( something like params="uid, rowInput::value" ) but it's 
incomplete and only for ajax events.

Concerning the problem of getListData in process of a row:
Process is evaluated well before the list is displayed, to strip the 
renderlet from the memory really early if process=false; thus it's not 
executed once per row, but once for the page, at the init() time.

This is the purpose of /datahandler/process/beforedisplay

Use it like this:

<datahandler:LISTER>
	<tablename>pages</tablename>
	<keyname>uid</keyname>
	<labelname>title</labelname>
	<process>
		<beforedisplay>
			<userobj>
				<php><![CDATA[
				
	$aRowHtml = func_get_arg(1);
	$aListData = $this->oDataHandler->_getListData();
	
	if($aListData["title"] == "I don't want this") {
		$aRowHtml["value"] = "";
	}

	return $aRowHtml;
					
				]]></php>
			</userobj>
		</beforedisplay>
	</process>
</datahandler:LISTER>


PS: you should take the step to renderlet:LISTER ;)
