Meh! Yes! It has an “optimization” if the form was submitted. Usually the request handler is what translates null into the page.

Just override invokeAction() and if the result is null then no action matched the URL. That is your queue to set a conditional boolean to cause the informational message to be shown.

Override invokeAction() in the page-level component? When I do this:

@Override

public WOActionResults invokeAction(WORequest request, WOContext context) {

WOActionResults result = super.invokeAction(request, context);

System.out.println("invokeAction: result = " + result);

if (result == null) {

// Do something...

}

return result;

}

result comes back as an instance of the page component when the action method is not invoked, not null. Any clues?

Oh, hold on—this does appear to work for a WOHyperlink in my minimal test app. Have I incorrectly assumed a WOHyperlink (the example in my original post) and a WOSubmitButton (what I’m actually using) would work the same way here?
