  • Thread-topic: EOF bug?

Hi all,

After much time and effort, I’ve traced a problem in my code to what appears to
be a bug in EOF’s _EOExpressionArray.

Let me state first that we’re way behind in our Wonder version, so it’s
possible that Wonder has fixed this already, but a quick search didn’t find it.
(We’re planning to catch up to current in the next few months.)

The problem seems to stem from the fact that _EOExpressionArray extends
NSMutableArray, but it doesn’t reimplement objectsNoCopy(). This is a problem,
because _EOExpressionArray uses it’s own internal array, not the superclass’s.
There’s a critical point in EOAttribute._normalizeDefinitionPath() where
objectsNoCopy() is called but returns null, even though the _EOExpressionArray
has elements, because it’s referencing the superclass array instead of the one
local to _EOExpressionArray.

Has anyone seen this? Has it been patched? Thanks!

Regards,
Mark
