I am configuring my SP, JBoss 6.4 with Picketlink. The login is successful, however when I am redirected to my portal I receive this error message:

11:40:55,079 ERROR [org.picketlink.common] (http-localhost/127.0.0.1:8080-3) Error parsing the response from the IDP. Check the strict post binding configuration on both IDP and SP side.
11:40:55,079 ERROR [org.picketlink.common] (http-localhost/127.0.0.1:8080-3) Service Provider could not handle the request.: ParsingException [location=null]org.picketlink.common.exceptions.ParsingException : PL0065: Parser : Unknown xsi:type=xs:boolean

Any ideas?
Thanks
