[hibernate-dev] Hibernate Integrator Causes Flush When Using JPA Transactions Around Queries

[Wolfgang Wedemeyer]

Greetings Hibernate Developers!

I'm working on an Integrator for Hibernate (background on Integrators: https://docs.jboss.org/hibernate/orm/4.3/manual/en-US/html/ch14.html#objectstate-decl-security <https://docs.jboss.org/hibernate/orm/4.3/manual/en-US/html/ch14.html#objectstate-decl-security>) that by using listeners is supposed to take my data from how it's stored in the DB and convert it into a different form for processing at runtime. This works great when saving the data using .persist() however there's an odd behavior involving transactions. It appears that since the Integrator does a modification on the entity in question it gets marked as "dirty" and upon committing this odd transaction, it bypasses my event listeners and writes the value back in the wrong format! How can I write my Integrator to behave correctly in this case so that I can "undo" the conversion that has happened with my entities at runtime and not flush the wrong value out?

I have further details including quickstart tutorial code that uncovered the issue for me posted on Stack Overflow: http://stackoverflow.com/questions/31671824/hibernate-integrator-causes-flush-when-using-jpa-transactions-around-queries <http://stackoverflow.com/questions/31671824/hibernate-integrator-causes-flush-when-using-jpa-transactions-around-queries>
but have yet to receive any responses. Feel free to reply there or send me a response back to this email if you can be of assistance.

Thanks,
