I already ran EOGenerator once, but that was before I added the fetch
spec. So I just ran it again, but it said that all files were
identical and would not be overwritten.
I may well have messed up on creating this fetch spec; it wasn't
totally obvious what to do, which makes sense if the "power users"
don't use this feature. All I did was highlight the EO called Panel
and clicked the "new fetch spec" button. I don't need a qualifier
because I want it to grab all rows. I did tell it to sort on the
description field, and gave it a meaningful name, but that was it.
Do I need to do anything else?
thanks,

I don't do the saved fetch spec thing either, but I highly
recommend that if you do, you should EOGenerate them into your
class files so you don't have this problem again. I think there's
an example of that on the wikibook page about eogenerator.

Ah... I tried that a while ago and got a different error, so I
thought it was wrong. But I have some printlns in there now and I
get my result.count() before the other error occurs, so now I know
you are correct. As if there was any doubt. :)

I'm not really a "fetch spec in the model" kind of guy, but the
mismatch between LicensePlate and Panel seems suspicious. The
second parameter to that function is the name of the entity where
this fetch spec is declared. It seems to me like this should be
Panel not LicensePlate.

I've just attempted my first fetch, and predictably it's not
working. This code:
EOEditingContext ec = session().defaultEditingContext();
EOFetchSpecification fs =
EOFetchSpecification.fetchSpecificationNamed("getAllPanels",
"LicensePlate");
NSArray result = ec.objectsWithFetchSpecification(fs);
results in an NPE on the last line.
I am not at all sure I created the fetch spec right; the fspec
file contains:
{
getAllPanels =
{
class = EOFetchSpecification;
entityName = Panel;
prefetchingRelationshipKeyPaths =
();
sortOrderings =
(
{
class = EOSortOrdering;
key = description;
selectorName = ascending;
}
);
};
}
How do I go about figuring out what I've done wrong?
