View Controller postbacks

["Baker,Jonathan" <Ba...@oclc.org>]

I am having an issue where new pages are returning true from the
isPostback method.  

I was looking at the source for ViewHandlerHandler, and saw that the
setupViewController method sets a context parameter if the view is a
postback

// Cache the postback flag so that it can be used inside
        // the AbstractViewcontroller implementation
        if (postBack) {
            context.getExternalContext().getRequestMap().
              put(FacesConstants.VIEW_POSTBACK, Boolean.TRUE);
        }

I believe the problem I am seeing, is that this context parameter is not
removed if postback is false.

E.g.
if (!postBack) {
            context.getExternalContext().getRequestMap().
              remove(FacesConstants.VIEW_POSTBACK);
        }

When I go to a new page, createView is being called, so
setupViewController is being called with postback=false.  Unfortunately,
the context already contains the VIEW_POSTBACK variable from the
previous page, that we reloaded when I clicked the commandLink to come
to the new page.

I am using standalone-tiles and trinidad if that makes any difference.
I found this jira issue but it was changed to not a problem:
