Albert Lee closed OPENJPA-1873. ------------------------------- Close issue in preparation for 2.2.0 release. > EntityManager#merge sometimes passes wrong entity values to @PostLoad > EntityListeners > -------------------------------------------------------------------------------------- > > Key: OPENJPA-1873 > URL: https://issues.apache.org/jira/browse/OPENJPA-1873 > Project: OpenJPA > Issue Type: Bug > Components: kernel > Affects Versions: 2.0.0, 2.0.1, 2.0.2 > Reporter: Mark Struberg > Assignee: Mark Struberg > Fix For: 2.2.0 > > Attachments: OPENJPA-1873-fix1.patch, OPENJPA-1873-fix2.patch, > OPENJPA-1873-fix3.patch, OPENJPA-1873-unittest.patch, > openjpa-1873-hack-1.patch, postloadtest.zip > > > I've tested this with the latest from branches/2.0.x. > My entity has an @EntityListeners which observes the @PostLoad lifecycle > event. This listener stores the 'old' values from the database for later use > (see http://struberg.wordpress.com/2010/07/31/howto-changelog-with-jpa/ for > the intention behind). All works well if the table has only a few rows. But > if you add more rows, OpenJPA tries to optimize the access and only loads the > @Version field + the dirty fields. In this case the merging seems to be > wrong, because I get the NEW values from the dirty fields instead of the > original values from the database passed to my @PostLoad method. > Did cost me a few grey hairs to track down the differences between the > working and the broken scenarios here ;) But finally I was able to creat a > unit test showing the problem -- This message is automatically generated by JIRA.
