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

17:34:45,428 ERROR [STDERR] at org.jboss.seam.Component.getInstance(Component.java:1598)

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?
