Switching Portlet Modes

A PortletMode represents a distinct render path within an application. There are three standard modes: view, edit, and help. The Bridge's ExternalContext.encodeActionURL() recognizes the query string parameter javax.portlet.faces.PortletMode and uses this parameter's value to set the portlet mode on the underlying portlet actionURL or response, but once processed it then removes this parameter from the query string.

The following navigation rule causes one to render the \edit.xhtml viewId in the portlet edit mode:

<navigation-rule>
  <from-view-id>/register.xhtml</from-view-id>
  <navigation-case>
    <from-outcome>edit</from-outcome>
    <to-view-id>/edit.xhtml?javax.portlet.faces.PortletMode=edit</to-view-id>
  </navigation-case>
</navigation-rule>
