I think that this is fixed. I cannot reproduce it anymore.
We receive a server error when try to send invitations from the inbox.
Caused by: java.lang.NullPointerException
at cc.kune.core.server.manager.impl.InvitationManagerDefault.invite(InvitationManagerDefault.java:185)
at cc.kune.core.server.rpc.InvitationRPC.inviteToSite(InvitationRPC.java:131)
at cc.kune.core.server.auth.AuthenticatedMethodInterceptor.invoke(AuthenticatedMethodInterceptor.java:84)

Because of the state token send (#group.tool etc) in the inbox seems that is empty/null.
