It appears the hibernate tool calls the toString() method on my object, which tries to invoke this field and thus the error. To work around i just changed my toString for now so it doesn't access this field. org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.sas.workflow.engine.mediation.hibernate.HibProcess.subprocesses, no session or session was closed at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationException(AbstractPersistentCollection.java:383) at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationExceptionIfNotConnected(AbstractPersistentCollection.java:375) at org.hibernate.collection.AbstractPersistentCollection.readSize(AbstractPersistentCollection.java:122) at org.hibernate.collection.PersistentSet.size(PersistentSet.java:162) at com.sas.workflow.engine.mediation.hibernate.HibProcess.toString(HibProcess.java:634) at org.hibernate.eclipse.console.views.QueryPageViewer$LabelProviderImpl.getColumnText(QueryPageViewer.java:86)  -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/733353#733353] Start a new discussion in JBoss Tools at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
