<f:view> erases conversation id UIViewRoot attribute in JSF 2 ------------------------------------------------------------- Key: WBRI-257 URL: https://jira.jboss.org/jira/browse/WBRI-257 Project: Web Beans Issue Type: Bug Components: Contexts Affects Versions: 1.0.0.PREVIEW1 Reporter: Dan Allen Assignee: Nicklas Karlsson Fix For: 1.0.0.PREVIEW2 JSF 2 now builds the view in the Render Response phase. If JSF encounters the <f:view> tag while building the view, it resets the UIViewRoot, wiping out any attributes that might have been set in a phase listener before the Render Response phase. Thus, the conversation id becomes a vicitim of this sweep: FacesContext.getCurrentInstance().getViewRoot().getAttributes().put(CONVERSATION_PROPAGATION_KEY, cid); This problem is not present in JSF 1 since the view is already constructed by the time this call is made by the WebBeansPhaseListener before the Render Response phase. The solution is to approach conversation propagation differently for JSF 2. Instead of using a phase listener, a SystemEventListener should be used that monitors the PreRenderViewEvent. SystemEventListeners can be registered programmatically, which should be done sometime after JSF 2 starts (the version of JSF can be detected in WebBeans) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
