Have you added a "public String getUsername()" method in your
LoginBean class? Seems that is missing. I don't think this error is
related to your managed property.
2006/6/1, [EMAIL PROTECTED] <[EMAIL PROTECTED]>:
Thanks
It seems I am a bit confused. I have added
<managed-property>
<property-name>loggedIn</property-name>
<value>#{loggedIn}</value>
</managed-property>
And I get the error:
javax.faces.el.EvaluationException: Cannot get value for expression
'#{LoginBean.username}'
