Hi List,

I have a document window that can show the same data in more than one way, very much like Finder, one view mode is an outline, the other is a collection. Both are bound to the same data, so they reflect changes automatically.

I was wondering if there is some way to tell a controller class (like NSArrayController) to temporarily disconnect the bound view from the data (other than removing the binding itself). It seems that the views are updating the data even if they are not visible, consuming memory and processor time. Moreover, NSCollectionView does seem to have problems when it's not visible and the data changes (I get debug log entries about assertion failures in NSView lockFocus).

Thanks
Markus
