[richfaces-issues] [JBoss JIRA] Closed: (RF-7456) rich:pickList crashing when associated with a variable for selected items

rich:pickList crashing when associated with a variable for selected items ------------------------------------------------------------------------- Key: RF-7456 URL: https://jira.jboss.org/jira/browse/RF-7456 Project: RichFaces Issue Type: Bug Components: component-input Affects Versions: 3.3.1 Environment: Windows Vista x64, WebLogic application server Reporter: Ruben Jorge Assignee: Andrey Markhel Fix For: 3.3.2.CR1 rich:pickList works fine getting the option values from a variable, but if I associate it with a value (so that I can access the selected values), it crashes. The XML code I've tried is the following: [code] <rich:pickList value="#{SessionBean.tempSelectedValues}" copyAllControlLabel="Add all" copyControlLabel="Add"> <f:selectItems value="#{SessionBean.tempDistincts}"/> </rich:pickList> [/code] tempDistincts and tempSelectedValues are defined as: [code] private List<SelectItem> tempDistincts = new ArrayList<SelectItem>(); private List<String> tempSelectedValues = new ArrayList<String>(); [/code] If I remove the "value" attribute from the pickList, the option values are presented correctly, otherwise, the following error is generated: [code] java.lang.NullPointerException at org.ajax4jsf.util.ELUtils.getGenericCollectionType(ELUtils.java:144) at org.ajax4jsf.util.ELUtils.getContainerClass(ELUtils.java:174) at org.richfaces.component.UIPickList.getConverterForValue(UIPickList.java:93) at org.richfaces.component.UIPickList.getConverter(UIPickList.java:72) at org.richfaces.renderkit.PickListRenderer.encodeRows(PickListRenderer.java:245) at org.richfaces.renderkit.PickListRenderer.encodeSourceRows(PickListRenderer.java:359) at org.richfaces.renderkit.html.PickListRendererGen.doEncodeChildren(PickListRendererGen.java:371) at org.richfaces.renderkit.html.PickListRendererGen.doEncodeChildren(PickListRendererGen.java:279) at org.ajax4jsf.renderkit.RendererBase.encodeChildren(RendererBase.java:120) at javax.faces.component.UIComponentBase.encodeChildren(UIComponentBase.java:826) at org.ajax4jsf.renderkit.RendererBase.renderChild(RendererBase.java:277) at org.ajax4jsf.renderkit.RendererBase.renderChildren(RendererBase.java:258) at org.richfaces.renderkit.html.ModalPanelRenderer.doEncodeChildren(ModalPanelRenderer.java:387) at org.richfaces.renderkit.html.ModalPanelRenderer.doEncodeChildren(ModalPanelRenderer.java:382) at org.ajax4jsf.renderkit.RendererBase.encodeChildren(RendererBase.java:120) at javax.faces.component.UIComponentBase.encodeChildren(UIComponentBase.java:826) at javax.faces.component.UIComponent.encodeAll(UIComponent.java:936) at javax.faces.render.Renderer.encodeChildren(Renderer.java:148) at javax.faces.component.UIComponentBase.encodeChildren(UIComponentBase.java:826) at org.ajax4jsf.renderkit.RendererBase.renderChild(RendererBase.java:277) at org.ajax4jsf.renderkit.RendererBase.renderChildren(RendererBase.java:258) at org.richfaces.renderkit.html.PanelRenderer.doEncodeChildren(PanelRenderer.java:220) at org.richfaces.renderkit.html.PanelRenderer.doEncodeChildren(PanelRenderer.java:215) at org.ajax4jsf.renderkit.RendererBase.encodeChildren(RendererBase.java:120) at javax.faces.component.UIComponentBase.encodeChildren(UIComponentBase.java:826) at javax.faces.component.UIComponent.encodeAll(UIComponent.java:936) at javax.faces.component.UIComponent.encodeAll(UIComponent.java:942) at javax.faces.component.UIComponent.encodeAll(UIComponent.java:942) at com.sun.faces.application.ViewHandlerImpl.doRenderView(ViewHandlerImpl.java:273) at com.sun.faces.application.ViewHandlerImpl.renderView(ViewHandlerImpl.java:204) at org.ajax4jsf.application.ViewHandlerWrapper.renderView(ViewHandlerWrapper.java:100) at org.ajax4jsf.application.AjaxViewHandler.renderView(AjaxViewHandler.java:176) at com.sun.faces.lifecycle.RenderResponsePhase.execute(RenderResponsePhase.java:110) 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 weblogic.servlet.internal.StubSecurityHelper$ServletServiceAction.run(StubSecurityHelper.java:22 7) at weblogic.servlet.internal.StubSecurityHelper.invokeServlet(StubSecurityHelper.java:125) at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:292) at weblogic.servlet.internal.TailFilter.doFilter(TailFilter.java:26) at weblogic.servlet.internal.FilterChainImpl.doFilter(FilterChainImpl.java:42) at org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:178) at org.ajax4jsf.webapp.BaseFilter.handleRequest(BaseFilter.java:290) at org.ajax4jsf.webapp.BaseFilter.processUploadsAndHandleRequest(BaseFilter.java:368) at org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:495) at weblogic.servlet.internal.FilterChainImpl.doFilter(FilterChainImpl.java:42) at weblogic.servlet.internal.RequestEventsFilter.doFilter(RequestEventsFilter.java:27) at weblogic.servlet.internal.FilterChainImpl.doFilter(FilterChainImpl.java:42) at weblogic.servlet.internal.WebAppServletContext$ServletInvocationAction.run(WebAppServletContext. java:3496) at weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:321) at weblogic.security.service.SecurityManager.runAs(Unknown Source) at weblogic.servlet.internal.WebAppServletContext.securedExecute(WebAppServletContext.java:2180) at weblogic.servlet.internal.WebAppServletContext.execute(WebAppServletContext.java:2086) at weblogic.servlet.internal.ServletRequestImpl.run(ServletRequestImpl.java:1406) at weblogic.work.ExecuteThread.execute(ExecuteThread.java:201) at weblogic.work.ExecuteThread.run(ExecuteThread.java:173) [/code] Also tried using 3.3.2-snapshot.
