Modules and singleton manager classes

This is a bit more of a “gotcha” than a tip, but it is something I’ve run into twice in the past week or so. When working with application domains and singletons (such as the DragManager or PopUpManager). I’ve been playing with modules the past couple days and ran into an issue when trying to drag items from a DataGrid in one module to a DataGrid in the second module. When trying to select an item in one of the data grids, I’d get strange run-time errors. The solution? Create a reference in my main application to a dummy DragManager or PopUpManager instance.

Hopefully this will save somebody a little bit of a headache in the future.

Full code after the jump.
