      the program startups success,but when I edit the course and click save button,the page return "model validation failed" message!
      follows is error page:

      "Course Name

      Any idea to solve it ? Is it a bug ?

          I wouldn't jump to it being a bug just yet. Most likely there is a restriction in the Hibernate validator that perhaps wasn't being applied before. I will try to take a look at it, but I am pretty jammed for time right now.

          However, what I can promise is that I am going to see if IBM will let me attach a Seam 2.0 version of the examples for the articles. That way you can be sure it will work ;) Don't expect anything in the next week though...I have a major deadline for Seam in Action that I am racing to meet.

            thank your reply.
            I traced the Seam 2.0 source and myfaces 1.2 source.And I Found that problem caused by myface 1.2 bug.
            In PropertyResolverToELResolver.java:
            private T invoke(ELContext context, Object base, Object property, ResolverInvoker invoker)
            myfaces set context.setPropertyResolved(true);
            but In PropertyResolverToELResolver.java:
            public Object getValue(ELContext context, Object base, Object property)
            myfaces return null, that cause the model validation failed

              the bug has been reported at myfaces MYFACES-1670,
              https://issues.apache.org/jira/browse/MYFACES-1670
              is fixed in myfaces 1.2.1.
              so I downloaded myfaces 1.2.1 snapshot and replaced myfaces 1.2.0 with it,I found everything is ok.
