two way bindings?

Hi,

Help! I can't properly get bindings from a custom view to work...

I have a custom audio sample view with a selection and a cursor. I 
bind these to keys in the selected object of an array controller. A 
table view is also connected to this array controller displaying all 
the entries. Now when I add entries to the table they get commited to 
the array controller and also the audio view updates when I change the 
values, but when I change the selection or the cursor in the view with 
the mouse, this does not get commited to the currently selected row in 
the table as it should. In turn if I use an NSSlider instead of my 
view communication works both ways, as expected. Now the relevant keys 
of the sample notify changes manually with willChange and didChange. 
Also mltiple changes are nested properly and I also properly overload 
automaticallyNotifiesObserversForKey (as documented anyway). Are there 
any further pitfalls I need to be aware of?

Best

Daniel
