Thanks guys, what you say makes sense... but my "widget"
grammer is a little limited still; would the syntax be something
like:
<fd:field id="key" required="true">
<fd:on-value-changed>
<javascript>
var thisWidget = event.source.lookupWidget("key");
if ( thisWidget.value() == "" ) {
thisWidget.setState ( WidgetState.ACTIVE)
} else {
thisWidget.setState ( WidgetState.OUTPUT)
}
</javascript>
</fd:on-value-changed>
</fd:field>
or, if not, then what (the above does not actually work;
seems thisWidget is null... but I am sure there are other
errors too...)?
Thanks
Derek

That's exactly what I was about to propose: changing the widget's state
on value change is what you're looking for!
