Hello,
I've got a modular application where I popup a TitleWindow for an import
Wizard. From there, I try to open a Window with a DataGrid inside. In
addition to a bunch of cFF font warnings, this error is thrown:
TypeError: Error #1007: Instantiation attempted on a non-constructor.

The specific line that throws the exception is:
var headerBGSkin:IFlexDisplayObject = new headerBGSkinClass();
Anyone got a clue? I'm able to bring the spreadsheet up in my TitleWindow
without issues, but when I try to put it in its own window. all hell breaks
loose.
