Steps to reproduce:
- build showcase.war file with MyFaces JSF, and the PartialStateSavings context-param set to false in web.xml:
<context-param>
    <param-name>javax.faces.PARTIAL_STATE_SAVING</param-name>
    <param-value>false</param-value>
</context-param>

- go to showcase -> ace:dataTable -> Table Configuration demo.
- open the Table Config and change the order of columns, submit the change -> a Server Internal Error popup occurs, and the server error is visible in tomcat log.


This issue could not be reproduced using Mojarra JSF, and PartialStateSavings=false.
