removal aware list
Hello all,
I have an M:N collection that has a ManageableArrayList as collection class
and proxy set to true. But when the collection is materialized the
underlying implementation becomes RemovalAwareList. When i remove items from
that list the records are also deleted. I tried to find out how that can
happen with the debugger but i cannot find out why.
regards,
Dennis

Yes, I have a system with about 600 entities, several are M:N, and all
are proxies.
I can't reproduce either.
I'm using 1.0.3.
Regards,
Richter

While describing i found out that there was another M:N collection
that did not specified the collection class. While stepping i thought
it was the other, thanks and sorry to have bothered you with this
because nothing is wrong.
Cheers,
Dennis

I tried to reproduce your test (m:n reference + proxy) without success -
I always get a ManageableArrayList instance. I'm using latest from SVN
(OJB_1_0_RELEASE branch).
Could you exactly describe how to reproduce your problem.

Richter,
I use 1.04 and explicitly configured ojb not to use a RemovalAwareList. I
explicitly configured ojb to use a ManageableArrayList. But still i get a
RemovalAwareList out of the proxy class's getData method.

Dennis

As name said, it's a "Removal Aware". If you don't wish objects removed,
don't use "RemovarAware". The default implementation is not
"RemovalAwareList", so it's sufficient to remove the specific
implementation on mapping.
IT: some older versions of OJB used RemovalAwareList as default - so,
please, if you are not using 1.0.3 or 1.0.4, upgrade your version (check
mail list about changes that could affect your upgrade).

Richter
