Help! JSF keeps barfing: Non-serializable attribute
I keep getting the following exception whenever I try to hit a JSF page:
java.lang.IllegalArgumentException: setAttribute: Non-serializable attribute

The code of my JSF page is pretty simple:
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<f:loadBundle basename="messages" var="msg"/>
<f:view>Hi there!</f:view>
What the heck could I possibly be doing wrong?
