I am getting this error when clicking on a sort order
button and also when trying to create a new record
(Object) for a particular entity that has both a Many
and To One relationships set up.
I assume it is something wrong with the configuration
of my EOModel.
Does anyone have some quick tips/guidelines on
configuring EOModels (i.e make sure the lock icon is
off/on, make sure the relationships have/don't have
the diamond icon enabled, etc...). Or if you know of
common issues causing these NullPointer errors.
Thanks in advance
Toby
