Well, some mandatory parameter of some component must not be null :-)
How about giving us a bit more? Page template, page class, line in the
template at which the error occurs...

I'm trying to get the DynamicSelectionList component working in an
existing Tapestry 4.0 project.
http://lombok.demon.co.uk/tapestry4Demo/
I copied all of the source files from the custom class example into my
own packages, but when I try to submit the form on the page, I get this
error:
org.apache.hivemind.ApplicationRuntimeException
Parameter name must not be null.
Any ideas? Thanks!
