I have updated the org.jboss.portal.api package with a new kind of event and an interface which expose a part of the navigational state managed by the portal. The event is RenderPageEvent and it allows listeners to be aware of when a page is rendered by the portal. The interface for navigational state is NavigationalStateContext and is available from the PortalNodeEventContext provided in the listener callback | public interface PortalNodeEventListener | { | PortalNodeEvent onEvent(PortalNodeEventContext context, PortalNodeEvent event); | } | | public interface PortalNodeEventContext | { | ... | NavigationalStateContext getNavigationalStateContext(); | ... | } | | public interface NavigationalStateContext | { | WindowState getWindowState(PortalNode window) throws IllegalArgumentException; | void setWindowState(PortalNode window, WindowState windowState) throws IllegalArgumentException; | Mode getMode(PortalNode window) throws IllegalArgumentException; | void setMode(PortalNode window, Mode mode) throws IllegalArgumentException; | } | This allows for example to read or update the different window state when rendering a page : | if (event instanceof RenderPageEvent) | { | NavigationalStateContext nsctx = context.get NavigationalStateContext(); | PortalNode pageNode = event.getNode(); | for (Iterator i = pageNode.getChildren().iterator();i.hasNext();) | { | PortalNode child = (PortalNode)i.next(); | if (child.getType() == PortalNode.TYPE_WINDOW) | { | nsctx.setWindowState(child, WindowState.NORMAL); | } | } | } | There is a more complete example in the core-samples module which implement a complex set of constraint on the page. Please look at the API and look if nothing look fundamentally wrong because this is going to become part of the supported API.
