Minto van der Sluis updated ISIS-265: ------------------------------------- Attachment: 0004-Allow-new-objects-to-be-properly-stored.patch Debugging revealed the PojoAdapter.checkLock() was called with otherVersion = null. This resulted in checkLoch() throwing a ConcurrencyException. Adding a check on the value of otherVersion solved my problem. Actually instead of the changed if statement I preferred the following: if (otherVersion != null && otherVersion.different(version)) { .... This however resulted in failing unit test. In my opinion a sign that the unit tests are coupled too tightly to the implementation of the method. > NullPointerException when storing new objects > --------------------------------------------- > > Key: ISIS-265 > URL: https://issues.apache.org/jira/browse/ISIS-265 > Project: Isis > Issue Type: Bug > Components: Runtimes: Dflt > Affects Versions: 0.3.1-incubating > Reporter: Minto van der Sluis > Labels: patch > Fix For: 0.3.1-incubating > > Attachments: 0004-Allow-new-objects-to-be-properly-stored.patch > > > After switching from 0.2.0 to trunk creating new objects resulted into a NPE > with the following output to the screen: > java.lang.NullPointerException > at > org.apache.isis.core.metamodel.adapter.version.ConcurrencyException.buildMessage(ConcurrencyException.java:36) > at > org.apache.isis.core.metamodel.adapter.version.ConcurrencyException.(ConcurrencyException.java:50) > at > org.apache.isis.runtimes.dflt.runtime.persistence.adapter.PojoAdapter.checkLock(PojoAdapter.java:337) > at > org.apache.isis.viewer.html.context.PersistentRootAdapterMapping.checkVersion(PersistentRootAdapterMapping.java:56) > at > org.apache.isis.viewer.html.context.Context.getMappedObject(Context.java:284) > .... > See also mailing list messages: > 1) > http://mail-archives.apache.org/mod_mbox/incubator-isis-dev/201209.mbox/%3C20120904162634.498360cc2mehz2ca%40webmail.xup.nl%3E > 2) > http://mail-archives.apache.org/mod_mbox/incubator-isis-dev/201209.mbox/%3C20120905105456.3062774yn2htlylc%40webmail.xup.nl%3E -- This message is automatically generated by JIRA.
