Re: ArrayIndexOutOfBoundsException - OJB 1.0

I got rid of the factory and the extended class, and the stuff works now.
Thanks for your help,

'CustomizedOfferLineImpl' is of base class 'OfferLineImpl' and using 
this one?)

hmm, never tried this. But if 'CustomizedOfferLineImpl' is not 
declared in metadata, you will at the latest get problems when 
storing these objects. Do you get any other error logging before the 
ArrayIndexOutOfBoundException occurs?

In my local test I do:
- store an Project class object with a collection of SubProject 
objects (1:n Project to SubProject)
- clear cache and query the created Project
- get the Project with proxied SubProject reference (not materialized)
- serialize/deserialize Project
- get the first SubProject object from Project (materialization done 
without problems)

Is this test similar to yours?

Armin

Yes, very much the same...
I believe that it might be the factory and extension class thing that 
is causing the problems, but I will retry in a different setting.

thanks,

Re: ArrayIndexOutOfBoundsException - OJB 1.0

2004-07-05 Thread Armin Waibel 
Hi Martin,
I try to reproduce your problem without success. Could you please post a 
test case or detail describe (some pseudo code) what your are doing?
By the way, do you use anonymous keys in collection objects?

regards,
Armin

I found out that the problem occurs if the JavaServer Faces framework 
serializes an object and reloads it afterwards.

Is it forbidden to serialize and recreate OJB-created objects with 
proxies in it? Do I have to mark the lists created by OJB as transient?

But if they are transient, on recreation I will surely loose 
information...  Should I write a converter for myself, being able to 
materialize the proxy-objects before they are serialized and serializing 
only the materialized objects?

best regards,
Martin

The problem is that this failure occurs not always, but only from time

Anybody of you has a suggestion or a workaround? Or is this a bug?
