Web Option Limitations

A limitation exists with Web Option where it can display a Just-In-Time (JIT) page, even if a skeleton was previously generated for the screen. This limitation only occurs when:

• The function is a window function.
• The function has a confirm prompt (that normally appears in its own small window).
• The function displays with the confirm prompt, but was not displayed immediately before and without the confirm prompt.

For example, if a window function WinFun (with a confirm prompt) displays, and then, as a result of action on the WinFun page, a different function SelFun is displayed. In this case, when the user leaves SelFun, WinFun is immediately redisplayed with the confirm prompt, and the WinFun page displays in JIT mode.

This limitation occurs because although Web Option is able to determine that a confirm prompt (in its own window) is being displayed, it is unable to retrieve required details of the underlying window, such as its original window offset and attributes, which are required to process field offsets.

This limitation does not effect full-screen functions. It does not effect window functions that initially display without the confirm prompt and then redisplay with the confirm prompt when the user presses Enter.

There are two workarounds to this limitation:

• Ensure that window functions that have the option to show the confirm prompts always display without the confirm prompt. Require a command key such as Enter to be pressed before the confirm prompt displays. This is essential in situations such as the previous example, where control might have gone to a different function and can then return to the window function.
• When window functions do not have the option to display the confirm prompt, consider changing the window function to be a full-screen function.

Note: If a window function displays in JIT mode, this is only while the confirm prompt is displayed.When the window function displays without the confirm prompt, the generated skeleton is used. If the window function displays in JIT mode, normal application functionality is retained. However, functions specific to the generated skeleton, such as drop-down lists, are not available.
