[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-1278) Recent EL changes seems to break SeamTest

Stuart Robertson commented on JBSEAM-1278:
------------------------------------------

The debugger shed some light on the problem. 

In Application.java: 

   private static Application getRIApplicationImpl(FacesContext context) {
        ExternalContext extContext;
        if (context != null) {
            extContext = context.getExternalContext();
        } else {
            extContext =
                 FacesContext.getCurrentInstance().getExternalContext();
        }
        if (extContext != null) {
 
     return ((Application) extContext.getApplicationMap().
                 get("com.sun.faces.ApplicationImpl"));

        }
        return null;
    }
	

extContext is MockExternalContext. It delegates to MockServletContext, which doesn't contain a value for the key "com.sun.faces.ApplicationImpl" 


I started a thread on this at http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4042936#4042936

> which seems to be because the RI ExpressionFactory isn't being set when using SeamTest.  I pulled in a bunch of updates from CVS just prior to this showing up, and many of them were related to MessageBinding/Expression.  Wonder if that is related.
> The expression it's throwing on is:
>             setValue("#{identity.username}", userName);
