Displaying an alert while selection is changing in a NSOutlineView

Subject: Displaying an alert while selection is changing in a NSOutlineView

Hi,

I've a problem using NSOutlineView and I've found no answer to it yet.

When the user wants to change the current selection in an NSOutlineView, you
can tell the outlineview if you are accepting (or rejecting) the change by
implementing the "selectionShouldChangeInOutlineView" delegate.

The problem is when I display an alert within
"selectionShouldChangeInOutlineView", the NSOutlineView will continue to
call the "selectionShouldChangeInOutlineView", and I get an infinite loop
(the alert always dismiss and then redisplay). Does anyone has an idea how
to deal with this problem ?

Thank you in advance.
