Hi Laurie,
Thanks for the suggestion!
After digging into the Tomcat console logs, I've finally found out
what the problem is. Seems like my copy of validation-rules.xml was
corrupted. The arguments for the validateRequired method were wrong.
Corrected that and now it works fine :-)
Thanks for the reminder though on the tpye-casting for the form. That
could save me a lot of brain-cells some time down the line...
