data module
Hi,
I am having issues when using the deltaspike data module to persist
entities:
http://stackoverflow.com/questions/20722811/apache-delta-spike-queryinvocationcontext
I am using glassfish with JTA, with parent-child relationships, it appears
it will attempt to insert 2 entities which results in a constraint error.
I confirmed the duplicate inserts via wireshark and can confirm 2 insert
statements are sent.
I'm hoping for some direction, perhaps it is a configuration issue.

Hi,
With more testing, I believe it is a multitude of things:
1. incorrect implementation of .equals and .hashCode may cause entity
manager to not save changes or duplicate changes (duplicate inserts)
2. incorrect entity manager configuration such as loading an entity from
em1 and saving with em2 causes state to be lost. The example does not show
an Application-scoped EntityManager, but after I made the producer produce
an ApplicationScoped em, it worked fine.
There may be more caveats, but those are what I learned. I'll plan on
updating via github later this weekend.
Thanks,
Walter

I can writeup something when I'm completely finished, but I'm still having
issues with my real entities ...

Glad you were able to sort it out. An addition to the docs would be great! I believe the docs for the data module are currently the README in the git repo. Care to create a patch, or simply add them here via email? At the very least, please create a ticket so we don't forget to document this.
Real usage like this helps us make DeltaSpike better and easier to use. Thank you very much for helping us out!

It looks like glassfish and arquillian are correct, it appears to be an
issue with .equals and .hashCode. I found this out by starting from
scratch without a custom implementation for .equals and .hashCode which is
what eclipselink uses to determine if the entity is the same or not. This
might be a good item for the FAQ or at least my FAQ.
Thanks,
Walter

Ok, I'll try that after I check my configuration. I will update/check
persistence.xml to ensure it is properly configured, then test with
arquillian.

Can you recreate with an Arquillian test to see if it's just glassfish?—
