[seam-issues] [JBoss JIRA] (SEAMSOCIAL-19) WebClient example NPE in MultiServicesManagerImpl.connectCurrentService on facebook callback

[ https://issues.jboss.org/browse/SEAMSOCIAL-19?page=com.atlassian.jira.plu... ] Dominic Legare commented on SEAMSOCIAL-19: ------------------------------------------ I am able to reproduce it on JBoss AS 6.1 and Jboss Seam 3.1.0.Final. But instead of restarting the AS on step 3, I just come back few hours later on the server (callback.xhtml page) and I got this error bellow. If I retry to do the callback after the error, I'm able to connect. But I can't avoid this error. I took the SocialClient example from the 3.1.0 Final too. I got this stacktrace (don't count on SocialClient line number, I did some changes on it): {noformat} 2012-02-03 21:10:02,779 ERROR
