    Seam 2 issue with javax.el.MapELResolver

    guinotphil Apprentice

      Hello,

       

      I'm currently trying to deploy a seam 2 application from JBoss AS 4 to JBoss AS 7.

       

      I've having an issue with the javax.el.MapELResolver.getType() method. Indeed, the method in indirectly called from org.jboss.seam.ui.component.UIEnumItem.getValue(), so I need to get an Enum type.

       

      In JBoss AS 4 it was working fine as the server came with JBoss' own implementation of javax.el, the code of the method was :

      public Class<?> getType(ELContext context, Object base, Object property) throws NullPointerException, PropertyNotFoundException, ELException

      {

        if (context == null) {

          throw new NullPointerException();

        }

       

        if (base instanceof Map) {

          context.setPropertyResolved(true);

          Object obj = ((Map)base).get(property);

          return ((obj != null) ? obj.getClass() : null);

        }

        return null;

      }

       

      So, I was getting to right type of the property.

       

      JBoss AS7 comes with Sun'simplementation and has the following code:

       

      public Class<?> getType(ELContext context, Object base, Object property)

      {

        if (context == null) {

          throw new NullPointerException();

        }

       

        if ((base != null) && ((base instanceof Map))) {

          context.setPropertyResolved(true);

          return Object.class;

        }

        return null;

      }

       

       

       

      So, I always get Object.class and so can't get UIEnumItem to work. Is there a reason for this change on JBoss AS 7 ? Looks like a regression to me....

       

       

      Thank you
