I thought of hiding the second list field if it's not required, but 
I don't know how to do that either.
Try this...
Hmm, if I read the above I think he only wants to conditionalize the 
requiredness of selectionlist 2 in dependency on selectionlist 1, not 
the displaying.
See above :-)

This is what was called "optionally required" in discussions:

I have not used the XReporter expressions, but javascript using
<wd:validation>
  <wd:javascript>
    if (widget1 != null && widget2 == null) {
      widget2.setValidationError =
                             new ValidationError(general.required);
    } else {
      widget2.setValidationError = null;
    }
  </wd:javascript>
</wd:validation>
Nice.  How would I do that from flow?  I could use form.onValidate()... 
or, can this be done on a per-widget basis in v2?

Thanks,
mark
