Class DirectRenderFromEventAction
java.lang.Object
com.opensymphony.webwork.portlet.dispatcher.DirectRenderFromEventAction
- All Implemented Interfaces:
- Action
public class DirectRenderFromEventAction
- extends Object
- implements Action
When a portlet is targetted for an event
, the portlet will receive two
portlet requests, one for the event
phase, and then followed by a render
operation. When in the event
phase, the action that is executed can't render
any output. This means that if an action in the XWork configuration is executed in the event
phase, and the action is set up with a result that should render something, the result can't
immediately be executed. The portlet needs to "wait" to the render phase to do the
rendering.
When the PortletResult
detects such a
scenario, instead of executing the actual view, it prepares a couple of render parameters
specifying this action and the location of the view, which then will be executed in the
following render request.
