[jira] [Commented] (MYFACES-4127) Unexpected exception thrown when
FlowMap is injected on a RequestScoped bean
[ https://issues.apache.org/jira/browse/MYFACES-4127?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16152617#comment-16152617 ]
Thomas Andraschko commented on MYFACES-4127:
--------------------------------------------
As discussed in the mailing list, ApplicationScoped is not the right scope for it. I changed it to FacesScoped for now. Could you try it again?

> When @FlowMap is injected on a RequestScoped bean, and you try to use that object (which should be null since we are not inside of a flow), an unexpected exception is thrown. This was noted after JIRA issue: https://issues.apache.org/jira/browse/MYFACES-4126
