Drag & Drop between different windows

Hello all!

I’m using the DragDropLayouts add-on from the vaadin directory to build my app.

Basically what I have is a full size DDGridLayout to be filled by another full size DDGridLayout possibly in another window (popup I mean, no a native vaadin sub-window) to save room in the main application window.

Actually I’m not able and can’t find a way to drag and drop components between these two grids.

Is there a way to achive what I need?

Thanks in advance,
