Default Edit Formview error

I am using the formview control. Within its edit template I have a treeview,
which I populate programatically . Initially I had an item template in which
I had a button, which triggered the edit template. The treeview was
populated with the following code

Protected Sub FormView1_ItemC reated(ByVal sender As Object, ByVal e As
System.EventArg s)
If FormView1.Curre ntMode = FormViewMode.Ed it Or FormView1.Curre ntMode =
FormViewMode.In sert Then
Dim tw As TreeView
tw = New TreeView()
tw = FormView1.Row.F indControl("tre eview1")
tw.Nodes.Clear( )
GetFolders(Serv er.MapPath(""), tw.Nodes)
End If
End Sub

However when I change the formview's default view to edit I keep getting an
'Object reference not set to an instance of an object' error when I try to
find the treeview. I'm a bit stumped. Can anyone help? Regards, Chris.
