Thanks Gennady. So presumably my assumption about the cause here is
all wrong:
The problem appears to be that not all the models have loaded by
the time
that page is being displayed. Indeed, checking
EOModelGroup.defaultGroup()
shows between 1 and 4 or 5 of the 8 models have been loaded by the
time that
entity is needed on the default page. Sometimes the correct model
has
loaded, and the page is displayed. Other times it hasn't, and the
app bails
out with that error. By the time Application.didFinishLaunching() is
called, they're all loaded.
If they're loaded on demand, that doesn't explain this:
Error: java.lang.IllegalArgumentException: An object store for the
entity "Status" could not be found. Verify that the entity is
defined in an EOModel, and that the model is installed properly. To
see what models are loaded, you can try printing the return value of
EOModelGroup.defaultGroup() in your application.
It certainly is defined in an EOModel, and the EOModel is sitting in
an included framework. Can anyone suggest why I might get this error
on one run, and then get normal operation on the very next run? (I
don't have to do anything between runs. Just hit stop, launch again
and see if it works.)
