JP, just for your information, I'm still working on this filtering
thing. It is like the proverbial maze, where you go down one passage
after another discovering that each one is a dead end - or leads you
back to the start.
It is wearing me out, but I am still enjoying discovering all these
little pieces of the puzzle.
At this stage I have discovered that you can only set an auxiliary
qualifier on an EODatabaseDataSource (or EODistributedDataSource) but I
now realise I am working with a EODetailDataSource.
I have also discovered the EODataSourceFactory, but its method to set
the auxiliary qualifier also didn't work.
It's really weird - it's like there is no way to put an additional
qualifier on a detail data source, yet if I add a qualifier statically
to the EOModel it works just how I want it to. If I could only figure
out how to do it programmatically. I am now looking at subclassing
EODetailDataSource to see if I can do anything there.

PS I also found that the data source appeared the next time I went into
the relevant view. It was creating it at the stage of getting the data,
and kept the same source for future objects. So I could probably just
create my own as you mention, but this doesn't look like it will be of
any help unless I can figure out this auxiliary qualifier in any case.

Ray,
If you can't solve your dataSource problem (but you probably will),
you can build your editingContext and dataSource yourself.
Write a (or several) provider method in your controller class, and
write a rule setting the provider method.
JP.
