To implement your application's program logic, you can make connections between the visual and nonvisual parts just as you would in any VA Smalltalk application. However, in a Web Connection application, the connections are different from what they would be in an ordinary VA Smalltalk application. Most notably, most of the connections will be to attributes and actions of Form Data, and not to the fields and controls in your user interface.

The explanation for this lies in the way a Web application works. Each transaction in a Web application is triggered by a request from a client; but once a page is loaded, it remains static until it is replaced by the next page. Each page builds its contents based upon the information submitted on the previous page. The Form Data part is the gateway through which that information is made available.
