Hi

I've got an additional question: How do I save the processed data back 
to the database?

Tried with the usual $GLOBALS['TYPO3_DB']->exec_UPDATEquery but the 
$incomingFieldArray contains this additional field

_TRANSFORM_productdescription='RTE',

causing the update-query to fail because no such field exist in the 
database.

I used the below-mentioned to test the hook

function processDatamap_preProcessFieldArray($incomingFieldArray, 
$table, $id, &$pObj)
	{
		t3lib_div::debug($incomingFieldArray);
		$incomingFieldArray['tools']['toolname'] = 1;
	 
$GLOBALS['TYPO3_DB']->exec_UPDATEquery($table,'uid='.$id.'',$incomingFieldArray);
	}

Best regards
Simon
