gtk_tree collapse on view detach/reattach

["Stephane Mas" <stephane_mas hotmail com>]

Hi,

I'm having a little problem with a custom tree model that I wrote. I want to 
be able to add a large number of rows to the tree at various positions in 
the tree, so I'm using the idea listed at:
http://scentric.net/tutorial/sec-treemodel-add-rows.html#sec-treestore-adding-many-rows

This is perfect for what I need. The only problem is that the tree collapses 
when I detach/re-attach the tree view from the model. Would anybody know how 
to fix this from occuring, whether or not this is a bug in the tree code, 
etc.

regards,
S
