9.2.4. Page Policy

The window error-policy controls how pages react to aggregation errors. Most of the time pages are an aggregation of several portlet windows, and the action to take when an error occurs differs from other policies. When an error occurs, the policy can either handle it, or ignore it. If the error is ignored, it is handled by the portal policy. Possible actions taken after such errors are:
  • remove the window from the aggregation.
  • replace the markup of the window using a redirect to a JSP page.
