Hi Markus,
Assuming you are using a tab or wizard page, you can use a rule like this to
have your validation method called:
100 : (pageConfiguration = 'CreateCourse' and tabKey = 'Location') =>
validationKeys = ("validateLocation") [com.webobjects.directtoweb.Assignment]
You may have to use a custom validation delegate to get the validation message
to display: <https://github.com/wocommunity/wonder/issues/97>
