That would be easy enough if the expression language could check if a
value is null, but as far as I remember it can't yet. Wouldn't be
difficult to add but I don't have time right now. We need to revisit
that whole expression-language thing anyhow.
But as a workaround to get you moving forward, you can write some custom
validation code. Are you using flowscript? I've just added an example
today (in CVS) of how to specify a custom validation function. You can
check the value of a widget like this:
form.getWidget("mywidget").getValue() != null ...
