The answer should be in these docs on using itemEditors w/ the Spark DataGrid: help.adobe.com/en_US/flex/using/… — JeffryHouser

You reference the host control with the outerDocument property... so you would call outerDocument.DP_PRAT_INIT if you want to access that array. BUT, that array is private, so you have to make it public. Or, you can make a public function that you can call on outerDocument but ... yuck.

If I am understanding your code properly, you should access the data property of the GridItemRenderer which is the same as outerDocument.DP_PRAT_INIT[ddlTuVous.selectedIndex] except that it is better because you don't have possible index mismatches...

So, what you really want is:

data.prTuVous = ddlTuVous.selectedItem;
