Hi Philippe,
Practical WebObjects uses Eclipse, but there have been a lot of
improvements to the WOLips tools since it was published.
It is intended for a pretty experienced audience, but the concepts
are very valuable to start to wrap your head around even if you're a
beginner.
Check o
As far as I know there's no book covering WebObjects programming with
WOLips. Would Chuck's book "Practical WebObjects" be a good starting point
to learn the WO concepts with the IDE set aside (XCode vs. Eclipse)?

I was fairly sure that I have seen this in other situations, but it
might just have been using the EOUtilities methods which don't set
isDeep.
Charles, are your table names identical in the model? What code is
triggering the multiple selects on one table?

I got burned by this back in 2005 (there's a thread from 2005 where
Chuck and I discuss this problem -- isDeep = false also means that
cache in memory is bypassed)

So it appears (if I'm reading this code properly) that EOF merges
restricting qualifiers for single table inheritance. In
EOSQLExpression, if the fetch spec .isDeep() and if the
entity._isSingleTableEntity(), then it will merge the restricting
qualifiers together into a big EOOrQualifier (
Any advice?
That it the way it is. I don't know how easy it would be to
optimize these. EOF might expect there to be only a single entity
per result set.
I was pretty sure I was not seeing this behavior, so I verified it in
one of our apps:
to-many fault:

I would suggest to take a look at EODatabaseContext.Delegate. In
particular:
public NSArray
databaseContextShouldFetchObjects(EODatabaseContext dbCtxt,
EOFetchSpecification fetchSpec, EOEditingContext ec);
Cheers
