bitten by the beta 3 DragManager Bug

I’ve just found myself caught out by this bug (SDK-13983) in Beta 3 (released December 2007), and the quite substantial change in behaviour.

My application which is only a prototype – but quite heavy, was essentially built from Oct 2006 through to April 2007 and  worked happily in Apollo and in all AIR and Flex 3 releases since, until Beta 3, when the DragManagers of AIR and FLEX implementations diverged. The API remains pretty much the same, but the behaviour is quite different (documented here), and while my existing code compiles, it generates run-time error “ArgumentError: Error #2004: One of the parameters is invalid.” if the user dare drag my UI components, rendering it useless.

That it has been accepted as a bug and a fix/workaround created, and that that is visible in the public bug system is a good thing. It removes a lot of potential worry. That the fix is not available to the public (AFAIK we’ve had our last public beta before the final release) isn’t great for me as I am now in a catch 22.

  • The fix isn’t available to me until the final version is released.
  • I can’t continue to use my application compiled against Beta 2 as the install process for AIR currently demands Beta 3 of AIR
  • Beta 3 AIR  demands Flex Beta 3 SDK.

It’s late, so this is going on hold until morning, at which point I need to assess the impact and time required to make the changes to adopt the AIR drag-and-drop manager, or hold on until I can force the switch to the Flex drag-and drop manager when the final release is available. Or beg Adobe for access to a build later than 191577.

[…] With today’s availability of release versions of Flex 3 and AIR 1, I’ve finally had a chance to apply the DragManager workaround that I had a moan about last month. […]
