to avoid null pointer exceptions all over the place (and/or to
avoid having to write lots of code to check that the relationships
were non-null). I took the following steps:
You should never need to worry about that. If the to-many
relationships are null, you have overridden awakeFromInsertion
(and / or awakeFromFetch) and failed to call
super.awakeFromInsertion / awakeFromFetch. EOF automatically sets
these to empty arrays in the super implementation.
b) updated my EOGenerator templates so that the generated code
checks for null in the to-many relationship accessors and returns
an empty array if it is null
You should not need to do that, you still have a problem to hunt down.
I am not sure where to look next. I have double checked, and for
sure I am calling super's implementation on every method that I
override, but I still get null pointer exceptions if I don't
explicitly check the relationship accessors. I always thought this
was stupid EOF behavior, but had no choice but to override my
templates, because it was the behavior I was getting. It might very
well be thanks to something I'm doing elsewhere, but not sure where
else to looks because I've never been violating any of the rules set
forth by the vendor, and now I'm not violating any rules set forth by
the non-vendor user community (that I'm aware of).
But at any rate, at least the code works in predictable ways now, and
the added code in my templates shouldn't impose a noticeable
overhead, even if it's theoretically unnecessary. Next time I can
afford to spend a few hours researching the problem, I will have
another look and see if I can track down something else, or else
start an entirely new project to see if I can replicate the behavior
there and work backwards from that. I'll let you know and post to
the list if I find anything from those exercises. Thanks again for
the help!
