Daryl, Dave,
This is the Entity... It is a somewhat tricky one, but I think I got
it right:
Attachment:
StructureItem.plist
Description: Binary data
Let me know if clarification of anything in it is necessary.
I am doing this on 5.3, but should be able to test it against 5.4
sometime soon...

Is this with WO 5.4.x? What does the EOClassDescription look like
for your EO's? Are all the attribute keys strings?

Hi all,
I get a class cast exception on the server when I try to save a
certain type of EOs. With other types I do not have this problem.
This is a JavaClient issue, as you can see in the stack trace
below. I've added a breakpoint in the client app at a point where
I am done with the EO, just before saving, and the EO itself looks
fine to me, and it's EC passes validateForSave() without
problems... So, I am a bit confused. Also, it is hard to determine
exactly what makes this particular EO type fail to save, and
others not.
Any thoughts?
I'll keep trying to isolate the difference that makes this type of
EO cause this...
