This is a resend of the previous email with a more accurate title and
better organised detail.
This bug is blowing my mind as the behaviour is not deterministic.
I have three outline views that are contained in 2 different
NSViewControlled sub-xibs which get loaded into the a place holder
view in the main persistent document window. The outlines views are
only *occasionally* updated when new data is loaded into their
NSTreeControllers.
Failed attempts to localise the bug:-
1> Call reloadData many times from many different places.
2> In primary document xib add a debug window which displays the
contents of the managed object context using parallel tree controller
and outline views, the debug window is updated fine.
3> In primary document xib, replace NSViewController architecture with
direct outline views connected to the debug window's tree controller.
Both the debug window and the direct outline views updated.
4> Bind the sub-xibs outline view to the primary document window's
tree controllers. Debug window updates correctly but sub-xibs outline
views don't!
The sub-xib bindings are through the NSViewControllers
representedObject, which gets set not at awakeFromNib time but later
when the subview is activated.
Finally the non deterministic behaviour is that rarely one of the two
outline views, thought not always the same one, does get data updates
and once that happens that outline view seems fine thought the other
one still has no data.
So far I haven't tested the code on a single processor machine. My
code, however, does not explicitly launch any threads.
Cheers
Godfrey
