pickList without collectionType results in failure to lazily load ----------------------------------------------------------------- Key: RF-12608 URL: https://issues.jboss.org/browse/RF-12608 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: component-selects Affects Versions: 4.2.3.Final, 4.3.0.M2 Reporter: Ken H Assignee: Brian Leathem Labels: regression Fix For: 4.3.0.CR1 Original Estimate: 3 hours Remaining Estimate: 3 hours Changes to the selectManyHelper class in 4.2.3+ causes a lazy loading exception in hibernate when the backing collection is persistent and is not eagerly loaded. The problem seems to be that fetching the collection in SelectManyHelper.getConvertedValue bypasses the PersistentSet getter that would normally issue the lazy load request. Defining the collectionType (e.g. java.util.ArrayList) bypasses this issue. Ideally this method would detect Hibernate proxy collections and handle them appropriately. However, I realize that may cause a dependency so perhaps it would be enough to document this option and situation in the component reference. The stack trace for the exception is below: {code} [org.richfaces.log.Context] (http-localhost-127.0.0.1-8080-1) failed to lazily initialize a collection, no session or session was closed: org.hibernate.LazyInitializationException: failed to lazily initialize a collection, no session or session was closed at org.hibernate.collection.internal.AbstractPersistentCollection.throwLazyInitializationException(AbstractPersistentCollection.java:393) [hibernate-core-4.0.1.Final.jar:4.0.1.Final] at org.hibernate.collection.internal.AbstractPersistentCollection.throwLazyInitializationExceptionIfNotConnected(AbstractPersistentCollection.java:385) [hibernate-core-4.0.1.Final.jar:4.0.1.Final] at org.hibernate.collection.internal.AbstractPersistentCollection.initialize(AbstractPersistentCollection.java:378) [hibernate-core-4.0.1.Final.jar:4.0.1.Final] at org.hibernate.collection.internal.AbstractPersistentCollection.write(AbstractPersistentCollection.java:208) [hibernate-core-4.0.1.Final.jar:4.0.1.Final] at org.hibernate.collection.internal.PersistentBag.add(PersistentBag.java:291) [hibernate-core-4.0.1.Final.jar:4.0.1.Final] at org.richfaces.renderkit.SelectManyHelper.getConvertedValue(SelectManyHelper.java:350) [richfaces-components-ui-4.2.3.Final.jar:4.2.3.Final] at org.richfaces.renderkit.SelectManyRendererBase.getConvertedValue(SelectManyRendererBase.java:108) [richfaces-components-ui-4.2.3.Final.jar:4.2.3.Final] at javax.faces.component.UIInput.getConvertedValue(UIInput.java:1030) [jboss-jsf-api_2.1_spec-2.0.1.Final.jar:2.0.1.Final] at javax.faces.component.UIInput.validate(UIInput.java:960) [jboss-jsf-api_2.1_spec-2.0.1.Final.jar:2.0.1.Final] at javax.faces.component.UIInput.executeValidate(UIInput.java:1233) [jboss-jsf-api_2.1_spec-2.0.1.Final.jar:2.0.1.Final] at javax.faces.component.UIInput.processValidators(UIInput.java:698) [jboss-jsf-api_2.1_spec-2.0.1.Final.jar:2.0.1.Final] at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:1214) [jboss-jsf-api_2.1_spec-2.0.1.Final.jar:2.0.1.Final] at javax.faces.component.UIForm.processValidators(UIForm.java:253) [jboss-jsf-api_2.1_spec-2.0.1.Final.jar:2.0.1.Final] at org.richfaces.context.PartialViewExecuteVisitCallback.visit(PartialViewExecuteVisitCallback.java:55) [richfaces-core-impl-4.2.3.Final.jar:4.2.3.Final] at org.richfaces.context.BaseExtendedVisitContext.invokeVisitCallback(BaseExtendedVisitContext.java:321) [richfaces-core-impl-4.2.3.Final.jar:4.2.3.Final] at javax.faces.component.UIComponent.visitTree(UIComponent.java:1612) [jboss-jsf-api_2.1_spec-2.0.1.Final.jar:2.0.1.Final] at javax.faces.component.UIForm.visitTree(UIForm.java:371) [jboss-jsf-api_2.1_spec-2.0.1.Final.jar:2.0.1.Final] at javax.faces.component.UIComponent.visitTree(UIComponent.java:1623) [jboss-jsf-api_2.1_spec-2.0.1.Final.jar:2.0.1.Final] at javax.faces.component.UIComponent.visitTree(UIComponent.java:1623) [jboss-jsf-api_2.1_spec-2.0.1.Final.jar:2.0.1.Final] at org.richfaces.context.ExtendedPartialViewContextImpl.executeComponents(ExtendedPartialViewContextImpl.java:237) [richfaces-core-impl-4.2.3.Final.jar:4.2.3.Final] at org.richfaces.context.ExtendedPartialViewContextImpl.processPartialExecutePhase(ExtendedPartialViewContextImpl.java:217) [richfaces-core-impl-4.2.3.Final.jar:4.2.3.Final] at org.richfaces.context.ExtendedPartialViewContextImpl.processPartial(ExtendedPartialViewContextImpl.java:196) [richfaces-core-impl-4.2.3.Final.jar:4.2.3.Final] at javax.faces.component.UIViewRoot.processValidators(UIViewRoot.java:1170) [jboss-jsf-api_2.1_spec-2.0.1.Final.jar:2.0.1.Final] at com.sun.faces.lifecycle.ProcessValidationsPhase.execute(ProcessValidationsPhase.java:76) [jsf-impl-2.1.7-jbossorg-2.jar:] {code}
