Hello people, I am messing with an AdvancedDataGrid for the first time. Have read the Adobe docs and it appears that you can listen for ITEM_OPEN and ITEM_CLOSE and such and be able to access the current item. However, they in my case are always null. I am trying to figure out where in the tree hierarchy the user has clicked the mouse. Could someone give me a little nudge in the right direction? :) thanks, Libby Flex 3.x
