i seem to be experiencing some sort of voodoo data bindings. i have
several grids in an app that a user can drag rows of data between. i
have a "master" ArrayCollection that's tracking all the data. when i
set the "master" dataset like this:

mapLayers=new ArrayCollection(updatedLayers);
layersGrid.dataProvider=updatedLayers;

where "mapLayers" is the "master" & layersGrid is the data grid where
the data is initially dumped,  i get an unwanted data binding between
the layersGrid.dataProvider & mapLayers, ie when data is dragged off
the layersGrid, that row of data is removed from mapLayers. is this
expected behavior?

the work around is to add items to the "master" dataset individually
but that's not what i would have expected.

thanks.
