I'm getting a NPE with Seam 1.1.5 and JBoss 4.0.5 when calling

Component.getInstance(Class, boolean);

with a true value for the boolean.

The stack trace is:


  | 17:34:45,347 ERROR [STDERR] java.lang.NullPointerException
  | 17:34:45,426 ERROR [STDERR]     at org.apache.catalina.connector.Request.getAttribute(Request.java:835)

Seems like a problem with catalina to me...


  |     /**
  |      * Return the specified request attribute if it exists; otherwise, return
  |      * <code>null</code>.
  |      *
  |      * @param name Name of the request attribute to return
  |      */
  |     public Object getAttribute(String name) {
  | 
  |         if (name.equals(Globals.DISPATCHER_TYPE_ATTR)) {
  |     ...
  | 

Or am I being stupid?
