I've been having trouble with migrating extensions from CS5.5 to CC (in flex for now). Especially with Native Drag events.
For example NativeDragEnter event is not triggering when dragging something from swatch list to extension. When I drag something from the document itself, event gets triggered (but not every time, which is strange).
Other elements of the extension are working.
Everything is working fine in CS 5.5.
I am using Extension Builder 2.1, building with flex sdk 3.4. Max target version of Creative Suite has been set to CS 7, so the extension should work in CC.
Is anyone having similar problems? Some feedback would be appreciated.
Have you found any solution since the time you posted? I am currently facing a similar problem with dragging with HTML/URL flavors in flex and dropping in InDesign?
