[richfaces-issues] [JBoss JIRA] Resolved: (RF-2576) Make objects selection optional for the component. (was suggestionbox broken in 3.2.0 nightly 20080318)

Make objects selection optional for the component. (was suggestionbox broken in 3.2.0 nightly 20080318) ------------------------------------------------------------------------------------------------------- Key: RF-2576 URL: http://jira.jboss.com/jira/browse/RF-2576 Project: RichFaces Issue Type: Task Affects Versions: 3.2.0 Environment: RF nightly, JBossAS 4.2.2, JSF-RI ("Mojarra") 1.2_08 Reporter: Juergen Zimmermann Assigned To: Aleksej Yanul Fix For: 3.2.0 The following was working with 3.1.4 and 3.2.0CR3. Using nightly 20080318 rich:suggestionbox is broken (see stacktrace below). The problem seems to be the following: * Java objects are instantiated from a database by using Hibernate (inside JBossAS) * The Java objects, however, are only partially instantiated due to a lazy fetching strategy. For instance the suggestionbox needs the customers' lastname, but not all their orders. Therefore, the orders of each customer are not fetched from the database due to performance reasons. * suggestionbox resp. ScriptUtils.toScript() tries to iterate over the *NOT* fetched collection. Therefore, Hibernate throws a LazyInitializationException. * Why do you iterate over such a collection? Why do you need this? Here is the stacktrace: 2008-03-18 10:50:02,155 ERROR [org.hibernate.LazyInitializationException] failed to lazily initialize a collection of role: de.hska.kundenverwaltung.db.Kunde.bestellungen, no session or session was closed org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: de.hska.kundenverwaltung.db.Kunde.bestellungen, no session or session was closed at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationException(AbstractPersistentCollection.java:358) at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationExceptionIfNotConnected(AbstractPersistentCollection.java:350) at org.hibernate.collection.AbstractPersistentCollection.initialize(AbstractPersistentCollection.java:343) at org.hibernate.collection.AbstractPersistentCollection.read(AbstractPersistentCollection.java:86) at org.hibernate.collection.PersistentBag.iterator(PersistentBag.java:249) at org.ajax4jsf.javascript.ScriptUtils.toScript(ScriptUtils.java:80) at org.ajax4jsf.javascript.ScriptUtils.toScript(ScriptUtils.java:135) at org.ajax4jsf.javascript.ScriptUtils.toScript(ScriptUtils.java:85) at org.ajax4jsf.javascript.ScriptUtils.toScript(ScriptUtils.java:105) at org.ajax4jsf.renderkit.AJAXDataSerializer.asString(AJAXDataSerializer.java:40) at org.ajax4jsf.renderkit.AjaxRendererUtils.encodeAreas(AjaxRendererUtils.java:775) at org.ajax4jsf.renderkit.AjaxContainerRenderer.encodeAjax(AjaxContainerRenderer.java:125) at org.ajax4jsf.component.AjaxViewRoot.encodeAjax(AjaxViewRoot.java:633) at org.ajax4jsf.component.AjaxViewRoot.encodeChildren(AjaxViewRoot.java:505) at javax.faces.component.UIComponent.encodeAll(UIComponent.java:936) at com.sun.facelets.FaceletViewHandler.renderView(FaceletViewHandler.java:592) at org.ajax4jsf.application.ViewHandlerWrapper.renderView(ViewHandlerWrapper.java:108) at org.ajax4jsf.application.AjaxViewHandler.renderView(AjaxViewHandler.java:185) at com.sun.faces.lifecycle.RenderResponsePhase.execute(RenderResponsePhase.java:109) at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:100) at com.sun.faces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:139) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:266) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:143) at org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:276) at org.ajax4jsf.Filter.doFilter(Filter.java:165) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:230) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:179) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:432) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:84) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:157) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:262) at org.apache.coyote.http11.Http11AprProcessor.process(Http11AprProcessor.java:856) at org.apache.coyote.http11.Http11AprProtocol$Http11ConnectionHandler.process(Http11AprProtocol.java:566) at org.apache.tomcat.util.net.AprEndpoint$Worker.run(AprEndpoint.java:1508) at java.lang.Thread.run(Thread.java:619)
