[Closed] uvMod.getSelectedFaces() unwrap on multiple objects

Hi

I dont know of a way around this so if anyone could point me in the right direction it would be appreciated
however you get to it (script or manually) if you have an unwrap mod applied to more than one object i can only get the selected faces for, what seems like the first object, for example

create 2 boxes
Select both and apply an unwrap Mod
uvMod = Get the unwrap mod
select all the faces in the unwrap window of one box
uvMod.getSelectedFaces()
prints – #{1…12}
select all the faces of the other box
uvMod.getSelectedFaces()
prints – #{} ???

anyone know a way around this?

Thanks
Dave
