[richfaces-issues] [JBoss JIRA] (RF-13647) File Download throws exception

[Michal Petrov (JIRA)]

    [ https://issues.jboss.org/browse/RF-13647?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12971954#comment-12971954 ] 

Michal Petrov commented on RF-13647:
------------------------------------

Turns out Mojarra doesn't use jsf.ajax.request for commandButton/Link submission (it simply submits the whole form) and thus it doesn't include "javax.faces.source" as a request parameter, causing the NPE.
