       Body:
This is due to some of the data structures not being Serializable. I've modified the XWork / WebWork2 data structures, but ognl.OgnlContext is still not serializable, so we'll have to wait for that to be fixed.

Environment: Windows 2000, JDK 1.4.1_04, Tomcat 4.1.27-LE-jdk14

Description:
I'm running beta1 inside Tomcat 4.1.27-LE-jdk14 and I can't seem to
successfully run the http://localhost:8080/webwork-example/form2.jsp
example.  

I can submit the form once, but on the second attempt I get the
following exception:

SEVERE: Could not execute action
