We found out, that all error pages have to be in /portal-core.
But we don't have such a directory, because we created our own container war.

In Class: org.jboss.portal.core.model.portal.control.page.DefaultPageControlPolicy

We found this code:
String resourceURI = (String)properties.get(ControlConstants.PAGE_RESOURCE_URI_CONTROL_KEY);
if (resourceURI != null)
{
ControllerContext controllerCtx = controlContext.getControllerContext();
ControllerRequestDispatcher rd = controllerCtx.getRequestDispatcher("/portal-core", resourceURI);

So it's not possible to reffer thru some other package.
Please fix this or make it configurable!
