Using a spark list to show thumbnails and allowing multiple selection I have found that the order in list.selecteditems vector is not correct, after a lot of searching on the net it seems this is a bug ( http://bugs.adobe.com/jira/browse/SDK-30701 ).
Would appreciate if someone has a workaround for this or an update is available.
Otherwise it seems I have to control the click event and fill my own array of selected items.
I need the items selection in the same order they have been selected by the user, sorting will not help. The problem is that this user selecting order is not respected.
I'm trying to find a solution using the index change handler but it seems the base problem is that newindex is not correct.
