Hi all, I tried to use a Idp sample of Picketlink 2.6.0.CR1 in Wildfly 8.0.0.final and when I put user/password information I get this message:

The Identity Provider could not process the authentication request.

The exception throwed:

09:03:09,905 ERROR [org.picketlink.common] (default task-8) Service Provider could not handle the request.: java.lang.NullPointerException
