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-7.1.0.Alpha1-SNAPSHOT, 3.0.0-SNAPSHOT revision
54570b8e1267b00b76c60b0345fe79d5d2b175ef
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.
