Rational Developer for System z, Version 7.6

Flow message editor: Basic tab

The Basic tab of the flow message editor provides a simplified user interface that is very useful for creating input messages, output messages, and fault messages.

Linked with other tabs and with the Outline view

The Basic tab is linked with the Advanced tab, the Properties tab, and the Outline view so that when you select or modify a message element in one member of the group the other members are updated immediately to reflect the same state.

Therefore if you are working in the Basic tab and you need an advanced function you can quickly switch to the Advanced view, make the change, and return to the Basic view.

General features

Undo and Redo are supported.

If a message element contains an error it is decorated with a warning icon and an error message is displayed at the top of the editor view.

Left pane: hierarchy of messages and message elements

The left pane of the Basic tab contains a tree showing the hierarchy of the messages and message elements in the message file. You can expand messages and groups as in the Advanced tab.
Note: References to XML entities in externally referenced XSDs are displayed as read-only. Complex elements are not expanded.

Right-clicking a message or a message element opens a pop-up menu. Table 1 shows the actions that are available for each type of element:

Right pane: properties
