Is your editing context locked before calling incrementIt() ? I
would think that would solve your concurrency issue here.
If not, just synchronizing the method should solve the problem. It
may seem inelegant, but you really ARE solving 2 different problems...

try). It would work *if* the
UPDATE WHERE data was fetched from the original data in the
context, and not in the row data.
It gets more complex than this. One quick fix is to have each
EC in its own EOF stack. But that can be rather memory expensive.

You saved the changes, therefore delete 'theSection', but then you
tried to access 'theSection'. You should move the removeObject...

As Alexander said, it should be faulting automatically. Can you

Basically, when you ask for the value for a key, it IS still a fault,
because you haven't asked the array anything that the fault can't
answer. When you do count(), it can't answ

Personally, I would use the CountFetcher class from Jerry Walker...I
use it all the time. You give it a fetch specification, and it comes
back with the number of rows that would be returned:

He means, rather than have a to-many relationship, like this:
A <-->> B
just have this:
A <-- B
Then when you want a certain subset of B, you can just do a fetch,
where B.A == the A you want, plus whatever else you want to filter on.

Seems like other people have similar problems with bind variables:

According to this guy, the optimizer punts when bind variables are

I'm killing my database now. I'm querying against a table that has

takes over 20 seconds - without them, a few hundred milliseconds.

Then, in you connection dictionary, specify the plugin as

That is just off the top of my head, but it is worth a shot.
