Subject [jira] Created: (MYFACES-616) tree2 creates TWO cookies
Date Fri, 23 Sep 2005 22:11:27 GMT
tree2 creates TWO cookies
-------------------------

         Key: MYFACES-616
         URL: http://issues.apache.org/jira/browse/MYFACES-616
     Project: MyFaces
        Type: Bug
  Components: Tomahawk  
    Versions: Nightly Build    
    Reporter: Jan Dockx


Cookies for tree2 are generated by JavaScript, with as name the (simple) JSF id of the tree2
component, and as path the "current URL directory". However, in a normal JSF-to-JSF navigation,
the first time the tree is rendered, we came from another page, and the URL is the URL of
that previous page (in JSF, the URL is always 1 step behind). When we have server interaction
within the page the tree is on, after the first interaction, the URL is changed to the URL
of the second page, and a second cookie is created for that "URL directory". This is not an
issue in itself if both pages are in the same directory, but becomes apparent if they are
not.

This is probably hard to fix when looked at narrowly, because of the "URL is always 1 step
behind" JSF issue. The real issue is, however, that the path of the cookie should be the webapp
context, like JSESSIONID has, and not the "current URL directory". The viewId could then be
made part of the cookie name, to make it unique.

(Or, for an even more bold suggestion: we should get writ of the cookies, and store the state
in a hidden field. Cookies can be used for storing state across requests, but for tree2 that
is exactly what we don't want: we want to get the info to the server, let the server define
a new state, and then get that back.)
