[richfaces-issues] [JBoss JIRA] (RF-10989) Reimplement AbstractPanel.getActiveItem() more defensively

[ https://issues.jboss.org/browse/RF-10989?page=com.atlassian.jira.plugin.s... ] Jean ANDRE edited comment on RF-10989 at 11/18/11 10:59 AM: ------------------------------------------------------------ There is some strange behavior with this method. There is also a NPE when you had tab even if you set the activeItem attribute (bind to : activeItem="#{desktopTabController.activeTab}"). It is a veritable nightmare ! The behavior of the tab seems to be different when you enclose or not tab inside an outputPanel. When we remove the outputPanel, there no NPE but the tab does not refresh well when we close a tab. In both case, we are in trouble ! {code} <h:form id="tabbedForm"> <rich:tabPanel id="desktopTabPanel" switchType="ajax" headerPosition="top" headerLocation="center" activeItem="#{desktopTabController.activeTab}"> <rich:tab id="tab-workitems" name="tab-workitems" header="#{msg['desktop.tab.workitems']}"> <!-- --> <!-- WORKITEMS TAB --> <!-- --> </rich:tab> <c:forEach items="#{desktopTabController.desktopTabBean.tabElements}" var="tab"> <a4j:outputPanel> <rich:tab id="#{tab.id}" name="#{tab.id}" > <!-- --> <!-- DYNAMIC TABS --> <!-- --> <f:facet name="header"> <h:panelGrid columns="2"> <h:outputText value="#{tab.id}" /> <h:graphicImage value="/images/closeButton.png" styleClass="closeButton" onclick="closeTab('#{tab.id}');" /> </h:panelGrid> </f:facet> <ui:fragment rendered="#{tab.isTabClient}"> <!-- --> <!-- CLIENT TAB --> <!-- --> <ui:include src="client/listClient.xhtml" /> </ui:fragment> <ui:fragment rendered="#{tab.isTabWorkItems}"> <!-- --> <!-- WORKITEMS TAB --> <!-- --> <ui:include src="workItems/listWorkItems.xhtml" /> </ui:fragment> </rich:tab> </a4j:outputPanel> </c:forEach> </rich:tabPanel> was (Author: jorelia64): There is some strange behavior with this method.
