Are you sure the object is attached or at least merged and only after
that you set the date to null ?
In fact, I'm not, yet:-), OpenJPA expert but it look like the
modification happened when detached and so is ignored.

I suspect the issue may be related to the fact I've needed to turn off
use of the detached state fields in order for the BlazeDS
serialization to work properly.

Hi Jason,
How are you enhancing your POJOs ?
If you are not enhancing them at build time, please do it and give
us some
news.

Hi All,
I'm having some trouble with my OpenJPA application and could use
some
help.
I've got a web-based application using Flex and BlazeDS to front-
end my
web
container running Tomcat, Spring, OpenJPA, and a few other
technologies.
My
back-end database is PostgreSQL.
I've got a DAO layer that works with a number of annotated POJOs,
and
everything has been working fairly smoothly until I just tried to
merge a
detached object and set its Date (db timestamp) to null.
Somewhat surprisingly, the new null value seems to go undetected
by JPA
and
the field is never included in the generated update statement.
Hence the
date is not removed from my returned object.
Because I'm using Flex and BlazeDS, my POJOs are annotated to
disable
detached state field use.
I'm running this way as the documentation seemed to suggest this
should
work
w/o a detached state field - plus it avoids serialization issues in
BlazeDS
and ActionScript caused by the detached state field.
Is this a bug I'm seeing or how the system is supposed to work?
Versions, etc. as follows:
OpenJPA 1.2.1 (classes enhanced @ build)
JDK 1.6.x
PostgreSQL 8.3
Tomcat 6.x
Flex 3.3
Let me know if you need more info.
Thanks!
