    JBoss 7.1.0 Final: s:viewAction doesn't cast viewParam correctly

    Lukas Camra Newbie

      So far I was using JBoss 7.0.2Final without any problems. Today, I switched to JBoss 7.1.0.Final and I'm facing following problem. (I use Seam 3.1.0Final)

       

      On page I use f:viewParam and s:viewAction as follows:

       

      {code:xml}<f:viewParam name="entityId" value="#{selectedEntity}" />

      <s:viewAction

              action="#{entitySelection.selectEntityById(selectedEntity)}" />{code}

       

      The problem parameter of method entitySelection.selectEntityById is Long and not String. However, this fails because it's looking for a method with string parameter. I will get than following exception:

       

       

      Caused by: javax.faces.el.MethodNotFoundException: javax.el.MethodNotFoundException: /private/foo/bar.xhtml @23,73 action="#{entitySelection.selectEntityById(selectedEntity)}": Method not found: Proxy for view class: com.foo.bar.EntitySelection of EJB: EntitySelection.selectEntityById(java.lang.String)

      If try to invoke method action="#{entitySelection.selectEntityById(selectedEntity)}" using commandButton, it works fine.

       

      Then, I tried this in the seam-booking example and it fails as well:

      {quote}

      javax.el.MethodNotFoundException: /hotel.xhtml @14,74 action="#{bookingAgent.selectHotel(hotelId)}": Method not found: Proxy for view class: org.jboss.seam.examples.booking.booking.BookingAgent of EJB: BookingAgent.selectHotel(java.lang.String)

      {quote}

       

      Any ideas?

       

      Thanks,

      Lukas
