Code	See the sample code

You can find the following sample code for defining a portlet as extension point in the CentraSiteBUIExtension.gwt.xml file that is provided in the demos folder under the CentraSite installation folder.

<replace-with
class="com.softwareag.centrasite.bui.extension.client.portlet.PortletListener">
<when-type-is
class="com.softwareag.centrasite.bui.extension.core.client.IPortletListener"/>
</replace-with>

Important:

On a “custom” portlet defined as GWT extension point, whenever you execute a basic action (for example, Expand, Collapse, or Close) through the user interface, CentraSite internally sends a corresponding actionId to the GWT extension.
