[richfaces-issues] [JBoss JIRA] Commented: (RF-6947) NullPointerException when uploading with rich:fileUpload

[Nick Belaevski (JIRA)]

    [ https://jira.jboss.org/jira/browse/RF-6947?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12465619#action_12465619 ] 

Nick Belaevski commented on RF-6947:
------------------------------------

File upload code has been reworked to store data in application-scoped bean to avoid serialization happening in clustered environments. Filter puts it there when request comes and removes, when request is processed. 

FacesContext.getCurrentInstance() can be null in filter because request has not reached Faces Servlet. Probably, all file data got read before FacesContext appeared, I'll add call to setupProgressData() in parseRequest() so that it will be 100% called when FacesContext is available.
