Hi again,
I am still stuck in my (very simple) dialog management. Briefly, I have a modal dialog that allows the user to create objects whose attributes are derived from various fields. I need to set the a default value to one attribute of a newly created object (after clicking on a button); however this scheme:
[arrayController insert]
[arrayController setSelectionIndex:0]
[[arrayController selection] setValue:foo forKey:@"spam"]
fails, because the creation of the new object is postponed until next Runloop iteration (so when the arrayController is void, there is no selection). I tried KVO on the "content" key of arrayController, but it fails also, the observation message seems to be hold until the modal runloop exits.
Any possible alternative?
Thanks,
Vincent_______________________________________________
