ADF panelTabbed persistence issue with WebCenter Portal

Issue

 

Recently an issue was found working with ADF tabs. A panelTabbed component was added to a page with 'n' tabs, each of them had its own showDetailItem. The way this ADF component works is explained in this link; roughly speaking, there is a disclosed attribute in every tab where developer specifies when its content will be displayed. For instance:

       <af:panelTabbed childCreation="lazyUncached" id="pt2">
              <af:showDetailItem text="Tab1"
                                           id="sdi2"
                                           disclosureListener="#{pageFlowScope.utilBean.navigateToNode}"
                                           disclosed="#{navigationContext.currentNavigationModel.currentSelection.attributes['Target'] eq 'tab1' or param.p eq 'tab1'}"
                                           immediate="true">
                        <!--Task flow that will be displayed in that tab-->
                        <af:region value="#{bindings.taskflowTab1.regionModel}"
                             id="r3"/>
                        <!-- Navigation path to the tab, as it is defined in default-navigation-model.xml file-->
                        <f:attribute name="destination"
                                        value="app1/myTabPage/tab1"/>
               </af:showDetailItem> 
              <!--Other tabs here-->
         </af:panelTabbed>

Tabs are accessed via:

•  URL: Introducing an URL specifying the tab parameter, i.e. http://localhost:7101app1/faces/oracle/webcenter/portalapp/pages/myTabPage.jspx?p=tab1
• Click: Just clicking on the tab.

After deploying application to Development environment, the following issue was reported:


If a tab is clicked, then URL links to other tabs stop working properly. For instance, if tab number 4 is clicked, then URL links to tabs after number 4 stop working.

A Service Request was registered in Oracle Support and a tes case was provided. Pascal B., an experienced WebCenter Portal engineer, was able to reproduce the issue and found the cause:

It is an issue related to persistence storage. When a tab is clicked, the persistence for the selected tab is not set and the issue appears.

Solution

 

A workaround was provided which successfully solved the problem. By overriding the default ComposerChangeManager class to avoid persistence problems. Steps:

1. Create a java class to overwrite the default ComposerChangeManage: PortalComposerChangeManager.java

2. Set this custom ComposerChangeManager as default composer manager in the web.xml file:
Comment out the following
<!--
<context-param>
<param-name>org.apache.myfaces.trinidad.CHANGE_PERSISTENCE</param-name>
<param-value>oracle.adf.view.page.editor.change.ComposerChangeManager</param-value>
</context-param>
-->
Add the following:
<context-param>
<param-name>org.apache.myfaces.trinidad.CHANGE_PERSISTENCE</param-name>
<param-value>oracle.webcenter.portalapp.override.PortalComposerChangeManager</param-value>
</context-param>

3. Save all, deploy and test the application.

NOTE: As requested, here you may download a Tabs Sample Application where this issue is reproduced, and the same application where the issue is solved using the workaround.
