Antony Stubbs commented on PB-84:
---------------------------------
actually, come to think of it, the StringIndexOutOfBoundsException was probably
the reason why the Double wasnt being replaced, as the code threw the exception
before it got to that stage, and subsequent requests were retrieving the Double
and getting the class cast exceptions.
But regardless, your new implementation does seem to clarify the issues.

> Key: PB-84
> URL: https://issues.apache.org/jira/browse/PB-84
> Project: Portals Bridges
> Issue Type: Bug
> Components: common
> Affects Versions: 1.0
> Environment: Mac OS, Wicket Portlets, OpenPortal Portlet Container
> Reporter: Tim Boudreau
> Attachments: portals-bridges-common-1.0.4.jar
>
>
> I'm trying to get wicket portlet support working over OpenPortal. I've
> hacked together implementations of ServletContextProvider and
> PortletResourceURLFactory - just required exposing WicketFilter from the
> Application to get the necessary data. I can deploy a portlet, but...
> I'm getting this exception.
> java.lang.ClassCastException: java.lang.Double
> at
> org.apache.portals.bridges.util.PortletWindowUtils.getPortletWindowId(PortletWindowUtils.java:45)
> Looking at the code, this seems like a clear bug: The method casts to String
> here:
> (String)session.getAttribute(PORTLET_WINDOW_ID);
> and if null fills in the value with an instance of Double. If it's going to
> put a Double there, it should probably not expect a String - this exception
> will occur any time this method is called twice for a PortletSession, it will
> throw the CCE the second time it is called.
> Since the value is not used, probably simply changing it to
> Object portletWindowId = session.getAttribute(PORTLET_WINDOW_ID);
> would fix it.
