Any idea to solve it ? Is it a bug ?
Many thanks in advance!

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.

[davidclf]

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

[davidclf]

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.
