I agree - handling it in the [[JavaScript]] is less than ideal, as this would be an example of [http://en.wikipedia.org/wiki/Cross-site_scripting cross site scripting] (in the sense that a script would be calling a site other than the one it was served from - OK in this context, but might be blocked by some security controls).

Problem description from Per Thomson
I'm going to use an external WebService which check if an adress exist.
A year ago I tested using webservice a little so I shouldn't be quite unfamilar with that subject but . . . So far I have created a webservice client subclass from the WSDL.
Now I'm stuck about how to invoke the external webservice.
The client/user type in a new address on a page that use the AJAX_Library_for_Visual_DataFlex but the address has to be validated before a save may be performed.
Solving it
In overall the easy way would be to call the external webservice on the serverside. It is rather complex handling SOAP in javascript --Jka 15:03, 13 September 2007 (CEST)

General knowledge
attaching a javascript function to onBeforeSave (inside initForm):
oForm.onBeforeSave = function(oVdfForm, sTable){
alert("onBeforeSave: " + oVdfForm + " " + sTable);
}
