Some customers have asked us what changes went into the Flex SDK from Beta 3 to our release. I tried to find this information via our public bugbase, however, there didn’t seem to be one. Instead, I went through all of the developer changelists between these two public releases and made a list. Hopefully, this list will help your resolve any issues that you have moving from Flex 3 beta 3 to the released version. All of the changes were bug fixes.
AIR Component Changes:
SDK-13902: Download source link fails in AIR view source. (changes made to WindowedApplication class)
SDK-14062 : DragProxy does not show up in DataGrid when running on AIR
SDK-14544: Popups in an mx:Window were showing up behind the <mx:Window>. This bug affected Menus, Alerts, PopUps and Tooltips in AIR.
List Based Component Changes:
SDK-13908: Runtime error on dragDrop for DataGrid
SDK-13902: TileList did not recycle rows.
SDK-13807: Items disappear as you move items around and scroll in a Tree.
SDK-13977: Horizontal TileList and List with offscreenExtraRowsOrColumns dragDrop cursor position is incorrect on a scroll
SDK-13980: List component gets into a bad state with empty rows if you drag and drop and have offscreenExtraRowsOrColumns set.
SDK-13540: Runtime error when navigating List or Tree using pending simulator
SDK-13465: Unexpected toolTip shows up
Cross-versioning Bug Fixes:
SDK-14044: SWFLoader and SystemManager references to SystemManager were changed to ISystemManager.
Note: This was a manual process of me going through internal check-in emails for the period between Beta 3 and our release. Therefore, I might have missed a couple of bug fixes.
