With the Webui framework, you will be notified if any given action is triggered. You just need to call your own action listener ($ACTIONNAME) ActionListener. For example, to create your own action listener for CacheView, do as follows:

1. Call CacheViewActionListener.

2. Add a static inner class called CacheViewActionListener that extends org.exoplatform.ecm.webui.component.admin.listener.UIECMAdminControlPanelActionListener.

You will see the expected code below:

public class CacheViewComponent extends UIAbstractManagerComponent {

        public static class CacheViewActionListener extends UIECMAdminControlPanelActionListener

<UIWCMCacheComponent>{

    public void processEvent(Event

    <UIWCMCacheComponent>event) throws Exception {

        UIECMAdminPortlet portlet = event.getSource().getAncestorOfType(UIECMAdminPortlet.class);

        UIECMAdminWorkingArea uiWorkingArea = portlet.getChild(UIECMAdminWorkingArea.class);

        uiWorkingArea.setChild(UIWCMCachePanel.class) ;

        event.getRequestContext().addUIComponentToUpdateByAjax(uiWorkingArea);

        }

        }

        }

3. Create the src/main/java directory and launch mvn eclipse:eclipse. You can then launch your eclipse and import this new project.

4. Create a new configuration file called conf/portal/configuration.xml to register your action (see Register your UI Action) with the org.exoplatform.webui.ext.UIExtensionManager service.
