--------------------------------------
Summary: ResourceHandler#markResourceRendered() should be retained
during ajax rebuild
Key: MYFACES-4120
URL: https://issues.apache.org/jira/browse/MYFACES-4120
Project: MyFaces Core
Issue Type: Bug
Affects Versions: 2.3.0
Environment: TomEE 7.0.3 with MyFaces 2.3.0-SNAPSHOT
Reporter: Bauke Scholtz
While running OmniFaces IT suite on today's MyFaces 2.3.0-SNAPSHOT, I noticed a
bug in ResourceHandler#isResourceRendered() during an ajax navigation back to
the same view (more specifically, when FacesContext#setViewRoot() is invoked
with a new UIViewRoot of same viewId during an ajax postback).
During restore view phase, all already-rendered resources are correctly marked
via markResourceRendered(). However, this is in turn stored as a transient
UIViewRoot attribute. As a consequence, when the UIViewRoot gets changed during
the very same ajax request, they are all lost, causing isResourceRendered() to
incorrectly return false.
Basically, the markResourceRendered() of the previous view should be remembered
for the next view when PartialViewContext#isAjaxRequest() returns true and
isRenderAll() returns false.
