Subject [jira] [Commented] (MYFACES-4120) ResourceHandler#markResourceRendered() should be retained during ajax rebuild

Leonardo Uribe commented on MYFACES-4120:
-----------------------------------------

I checked the code and how it is handled this case on the javascript side and the whole head
tag is replaced, so anyway if we keep track of the resources added in a facesContext map,
it will be pointless, because the partial response from the server will be the same. I'll
close this issue as not a problem. Please reopen it again if you thing there is something
I'm missing in the resolution. Thanks Bauke for the report.

> 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.
> In MyFaces 2.2 (and possibly earlier) the behavior of markResourceRendered() and isResourceRendered()
was internally correctly implemented via org.apache.myfaces.RENDERED_SCRIPT_RESOURCES_SET
context attribute.
