Editing a Message Definition

Use the Message Definition Editor to edit a message definition by modeling a custom wire format message as a tree of containers and fields.

To edit a message definition:

In the WorkSpace Navigator of the Service Development perspective, expand the project that contains the message definition you want to work with.
Expand MessageDesigns, then expand MessageDefinitions.
Double-click the message definition you want to work with. The message definition has a .wfm extension.
The message definition opens in the Message Definition Editor.
Select the Message Details tab and perform the following actions in any combination:
- Add a container.
- Add a field.
- Drag and drop a container or field to another location in the tree.
  When you drag the field, a horizontal line appears, indicating the new location.
- Use accelerator keys to add child nodes and insert sibling nodes in the message tree.

To change message definition default settings:

You can change design-related default settings for custom messages after the message definition is created.

Right-click in the Message Definition editor and select Change design defaults. The Change Message Node Defaults dialog opens.
Use the tabs in the dialog to view and modify design-related defaults for Container, Field, Date / Time, Numeric, and Length.
Note
The Message tab of the Change Message Node Defaults dialog is read-only and displays the settings in place when the message definition was originally created.
