WebClient example NPE in MultiServicesManagerImpl.connectCurrentService on facebook callback -------------------------------------------------------------------------------------------- Key: SEAMSOCIAL-19 URL: https://issues.jboss.org/browse/SEAMSOCIAL-19 Project: Seam Social Issue Type: Bug Components: Facebook Environment: jboss-as-7.0.2.Final, seam social 3.1.0-SNAPSHOT (2011-10-31) Reporter: Marek Schmidt Assignee: Antoine Sabot-Durand Sometimes (but not always, but happened more than once... ) after a redirect from Facebook login, I see the following exception instead of the webclient callback page: I could not reproduce it by aggresive clicking after it happened, so I suspect it may occur after some session times out somewhere... also, I am not sure it is facebook-specific or not. {noformat} 10:43:00,308 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/social-web-client].[Faces Servlet]]
