ViewHandler.createView using SeamViewHandler.calculateLocale tries to use already released FacesContext when used outside lifecycle ----------------------------------------------------------------------------------------------------------------------------------- Key: JBSEAM-318 URL: http://jira.jboss.com/jira/browse/JBSEAM-318 Project: JBoss Seam Issue Type: Bug Components: Core Affects Versions: 1.0.1 Environment: JBoss 4.0.4.GA MyFaces 1.1.3 Reporter: Tuomas Kiviaho ViewHandler.createView can't be used outside lifecycle phases. The locale calculation done by seam view handler using locale selector ends up in a NullPointerException (should propably be t be IllegalStateException) in MyFaces external context implementation if FacesContext had already been consumed by Seam threadlocals (Contexts) One could ask why I am using createView outside lifecycle, but this is what happens when done so. StackTrace (NullPointerException): ApplicationMap.getAttribute(String) line: 42 ApplicationMap(AbstractAttributeMap).get(Object) line: 87 FacesApplicationContext.get(String) line: 46 FacesApplicationContext.get(Class) line: 79 Init.instance() line: 95 Component.getInstanceFromFactory(String) line: 1199 Component.getInstance(String, boolean, Object) line: 1176 Component.getInstance(String, ScopeType, boolean) line: 1169 LocaleSelector.instance() line: 123 SeamViewHandler.calculateLocale(FacesContext) line: 32 JspViewHandlerImpl.createView(FacesContext, String) line: 130 To tacle the symptom: 1. FacesContext.getExternalContext could be used inside Seam's FacesApplicationContext instead of direct reference to see if the context has been released by catching the IllegalStateException that MyFaces throws. 2. Using external context with RuntimeException precaution (3. Blame the messenger) But what then can be done inside Seam goes beyond my knowledge, since Seam's component instantiation is a core part of the system. Of course this step can be left alone just by a try/catch around locale selector instantiation and continuing with a warning. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
