[jbpm-issues] [JBoss JIRA] Commented: (JBPM-2845) Error changing value of Lob variable at jBPM 4.x

Error changing value of Lob variable at jBPM 4.x ------------------------------------------------ Key: JBPM-2845 URL: https://jira.jboss.org/browse/JBPM-2845 Project: jBPM Issue Type: Feature Request Security Level: Public(Everyone can see) Reporter: Per Christian Henden Fix For: jBPM 4.5 Attachments: lobvar.diff First reported by Paweł PoseŠon the community forums. See http://community.jboss.org/message/537481 I've attached a patch against jbpm-svn (r6256): Original report: I've noticed frequently such error during changing existing Lob varibale: Caused by: org.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade (remove deleted object from associations): [org.jbpm.pvm.internal.lob.Lob#110051] The source of this problem is at BlobVariable: public void setObject(Object value) { if (this.lob!=null) { DbSession dbSession = EnvironmentImpl.getFromCurrent(DbSession.class, false); if (dbSession!=null) { dbSession.delete(todel); } } this.lob = new Lob((byte[])value, true); } The solution of this problem: public void setObject(Object value) { if (this.lob!=null) { DbSession dbSession = EnvironmentImpl.getFromCurrent(DbSession.class, false); if (dbSession!=null) { Lob todel = this.lob; this.lob = null; dbSession.delete(todel); } } this.lob = new Lob((byte[])value, true); } Hope samobody from jBPM team correct this bug. Below whole stacktrace: org.jbpm.api.JbpmException: couldn't acquire block of ids at org.jbpm.pvm.internal.id.DatabaseDbidGenerator.getNextId(DatabaseDbidGenerator.java:65) at
