Thanks Alex, Here's the stack trace:

The app is constructed like so:
1) Shell application
2) Modules loaded at runtime
3) The module in question has a pop up wizard (TitleWindow).
4) The popup wizard opens Window.
5) Window contains DataGrid.
I don't understand how the module factory for the datagrid points to the module
factory for the module. How's that accomplished?

What is the Group stack trace? If classes are in a module you definitely have
to get the moduleFactory pointing to that module because that's probably where
the skins are as well.

What's unclear to me is how to work around it in my circumstance. Clearly I
should be able to declare a datagrid in a Window and have it work without an
elaborate workaround.
Any advice appreciated.

Hi,
I'm mid re-factoring a SDK 4.0 AIR app to 4.5 and attempting to take advantage
of the Spark DataGrid. In this app (which is built with modules) I'm openin!
g a NativeWindow and displaying a datagrid. The fi! rst erro r is that the
DataGrid Skin class cannot be found. I dealt with this by creating a new Skin
from the DataGrid and referencing that. Then when I attempt to populate the
grid with data, I get RTEs pointing to Group.as with error #1009 null.
I can get in to more exhaustive detail about the exact error(s) but I think
something more fundamental is happening. Note that the libs are all merged
into code. It seems that some of the underlying libraries aren' being included.
Does anyone have any experience or theories on what might be happening?
