Subject [jira] Created: (TOMAHAWK-887) Duplicate Client-Id
Date Thu, 08 Feb 2007 13:46:05 GMT
Duplicate Client-Id
-------------------

                 Key: TOMAHAWK-887
                 URL: https://issues.apache.org/jira/browse/TOMAHAWK-887
             Project: MyFaces Tomahawk
          Issue Type: Bug
          Components: Data Scroller
    Affects Versions: 1.1.5-SNAPSHOT
            Reporter: nikolaos georgosoulos


The datascroller component returns the following error when it is part of a portlet in page
and the user leaves the page and returns. The 1.1.5 snapshot is being used so the datascroller
works fine as long as the user stays in the portal page with the scroller. When user leaves
the page and returns back to it the error occurs. As portal Jetspeed 2 is being used. the
Tomahawk bridge is used for bridging portal and portlet of JSF that extend the MyFacesGenericPortlet
class without any real implementation (just super.doView()). Myfaces implementation is 1.1.4.
Myfaces impl 1.1.5 does not cooperate well with Tomahawk bridge (bufferedStream errors) and
the portals-bridge-jsf simply discards any passed parameters from the processAction to the
renderPage phases. I only mention these in order to prove there is none known alternative.
