I am very much a WO novice, just working my way through Ruzek's "WO

WOWACK is a little old now, being WO 4.5; but I still like it the
best of the entry level books.
Yes, it still seems to be usable. Well, it was usable given I had
worked through about half of it before upgrading to Leopard and losing
the Apple GUI tools. I don't know how someone would go starting from
scratch with WOWACK now...
What I
_thought_ I could do was replace the literal declaration of
fetchSpecification for the WODisplayGroup (which I just copied over
from something auto-generated from WO Builder) with a reference to a
method in the component's Java class that returned an
EOFetchSpecification. That is, instead of this:
dataSource = {
class = EODatabaseDataSource;
editingContext = "session.defaultEditingContext";
fetchSpecification = {
class = EOFetchSpecification;
entityName = Task;
fetchLimit = 0;
isDeep = YES;
};
};
I tried this:
dataSource = {
class = EODatabaseDataSource;
editingContext = "session.defaultEditingContext";
fetchSpecification = activeFetchSpec;
};
Try:
fetchSpecification = "activeFetchSpec";
for your binding, assuming that this is a method in the component
that returns a fetch spec.
That didn't _seem_ to work (it was the method returning an
EOFetchSpecification), but I've now changed several things since I
asked the question, most notably upgrading to WO 5.4. I've also
ditched the idea of using WODisplayGroups in the application anyway.
If I take another look at it later and work it out, I'll reply to the
list.
