    Seam Vaadin integration

    mariusz bogucki Newbie

      I am following the documantation that says that we have to add 


      <web:context-filter url-pattern="/VAADINApplication/*"
                                />




      in components.xml


      and it seems to solve half of the problems, after adding I have an access to all seam API like  it is mentioned by Ricardo Memoria in this post
      My Link


      problems appear whenever I try to use some of the actions that require active context like entityManager.find() etc.
      entity manager is not null and Manager.instance().getCurrentConversationId() returns conversation id


      and even though


      System.out.println("EVENT context active:" + Contexts.isEventContextActive());
      


      returns true I still get



      javax.servlet.ServletException: java.lang.IllegalStateException: No active event context
           org.jboss.seam.servlet.ContextualHttpServletRequest.run(ContextualHttpServletRequest.java:74)
           org.jboss.seam.web.ContextFilter.doFilter(ContextFilter.java:37)
           org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69)
           org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:178)
           org.ajax4jsf.webapp.BaseFilter.handleRequest(BaseFilter.java:290)
           org.ajax4jsf.webapp.BaseFilter.processUploadsAndHandleRequest(BaseFilter.java:368)
           org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:495)
           org.jboss.seam.web.Ajax4jsfFilter.doFilter(Ajax4jsfFilter.java:56)
           org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69)
           org.jboss.seam.web.LoggingFilter.doFilter(LoggingFilter.java:60)
           org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69)
           org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:73)
           org.jboss.seam.servlet.SeamFilter.doFilter(SeamFilter.java:158)
           org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)




      in documentation (29.1.4.8. ) it also says that I have to for ensure propagation of any new conversation id


      How do I do that?
      I tried to get the request object in my vaadin application servlet like this


      public void onRequestStart(HttpServletRequest request,
                  HttpServletResponse response) {
              HttpServletRequest oryginalRequest = (HttpServletRequest) ((IdentityRequestWrapper) request).getRequest();
      
              oryginalRequest = new HttpServletRequestWrapper(oryginalRequest);
      
              oryginalRequest = new AddableHttpRequest(oryginalRequest);
      
      


      AddableHttpServlet request is the class that I created and it extends HttpServletRequestWrapper and allowes to add new parameters
       
      When I execute



      oryginalRequest = new HttpServletRequestWrapper(oryginalRequest);



      everything is OK




      but when it gets to execute this




       oryginalRequest = new AddableHttpRequest(oryginalRequest);




      I get the same error as above with no active event context .
      I can wrap request in oryginal wrapper class but i can not wrap it in class that extends it ?
