Class PortletExceptionPresenter

java.lang.Object
  org.apache.tapestry.portlet.PortletExceptionPresenter

All Implemented Interfaces:

ExceptionPresenter

public class PortletExceptionPresenter
extends Object
implements ExceptionPresenter

Service used to present a runtime exception to the user. This is very tricky in the Portlet world because of the split between the action and render requests (much more likely to get an error during the action request than during the render request, but both are possible).

During an action request, this code will render the HTML markup for the exception into a buffer that is stored as persistent attribute in the portal session.

Since:

4.0
