Summary
Important Observations
- Procedural functions do not support the use of the browser's Back button. In order to go back in the procedural paradigm, the user must use an equivalent to the F12=Cancel key or button.
- You must always call your WEBEVENT functions directly. You can not call them from a process menu.
- When testing your Web function applications, remember to use one of the buttons (Next, Search, Menu, Ok, etc.) on the page to submit the data back to the server. Do not press the Enter key unless specifically instructed. If you wish to have the Enter key submit your page, you must add a JavaScript function to handle this event. Refer to Handle the ENTER key in Browsers.
Tips & Techniques
- The majority of your Web function applications will be built using WEBEVENT functions.
- If you are building applications for an Intranet, you may wish to Web enable your existing LANSA applications instead of rebuilding WEBEVENT applications.
