You will almost never need more than one data model in a form. However, you can easily add models if you need them.
To add a data model to an existing form:
- If you do not already have the Advanced IBM Forms Designer perspective open, click Window -> Open Perspective -> Advanced IBM Forms Designer.
- In the XForms view, right-click XForms and click Create Model. Designer adds the model to the form and updates the XForms view.
After you have created the model, you can change its name. To do that, select the model, and in the Properties view expand General
and type in a new name for the model.
