Hi all

I have developed a c2a target portlet which is working fine. However,
looking at the portal log I see 2 entries indicating some problem:

1. Every time a portlet action other than the c2a-action is fired on the
portlet (eg. normal portlet action), the PortletWrapper tries to propagate
an output property although no output property is defined in the wsdl-file.
The wrapper does not find an apropriate action an throws a protocol error.

Log entry (sendAction is my ordinary portlet action):
2004.10.12 13:11:44.078 m com.ibm.wps.pb.wrapper.PortletWrapperUtils
propagateOutParameters Servlet.Engine.Transports : 0
Action name:sendAction.

2. When updating the portlet application containing the c2a portlet, the
PortletWrapper throws a NullPointerException upon logout.

LogEntry:
Nested Exception is java.lang.NullPointerException
at com.ibm.wps.pb.wrapper.PortletWrapper.logout(PortletWrapper.java:716)
at org.apache.jetspeed.portlet.Portlet.dispatch(Portlet.java:574)
at org.apache.jetspeed.portlet.Portlet.doGet(Portlet.java:510)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:740)

Data.java:224)
at
com.ibm.ws.webcontainer.httpsession.SessionData.processListeners(SessionData
.java:912)
....

Any hints on these problems?

Thanks
