Reloading screen descriptions automatically

In most situations the host editor automatically reloads the screen descriptions for you, whenever a screen description in the current service flow project changes in some way on your workstation's hard disk.

Recall that reloading screen descriptions means that the host editor deletes the currently loaded screen descriptions from memory, and then loads into memory, from your workstation's hard disk, all the screen descriptions in all the screen messages that are present in the Messages folders of the all the terminal applications subprojects in the current service flow project. These screen descriptions then become the currently loaded screen descriptions (see Currently loaded screen descriptions).

The host editor automatically reloads the screen descriptions in the following situations:
Situation: Links:
When a new screen message (which always contains a new screen description) is created, by any of the following methods:
  • Capturing a screen in the host editor (manually or automatically).
  • Importing a BMS map.
  • Importing a HATS screen.
Creating a screen message
When an existing screen message is modified, by any of following methods:
  • Assigning BMS field names.
  • Merging screen messages.
  • Using the screen message editor to add, modify, or delete an screen description, and then saving the current state of the screen message editor.
When a screen message file is deleted. Working with screen messages

Important: The host editor does not reload the screen descriptions until the host editor regains the input focus. At that time the host editor performs the following actions.
  1. It checks to see whether any screen description has been created, modified, or deleted.
  2. If so, it reloads the screen descriptions (see Currently loaded screen descriptions).
  3. It performs the same screen recognition activity that it normally performs when a new application screen is displayed (see Recognized screen description).
    Note: Step 3 is done in case a new or modified screen description now matches the currently displayed application screen, or in case a screen description that previously matched the currently displayed application no longer does so.
