References to the Data Model 

Use

The data model defines the structure in which information in a XML document or its properties is stored.

All input fields, checkboxes, radio buttons, and combo boxes on the creation form must have a reference to an element of the data model so that the information entered can be saved.

To depict the stored information on display and list forms, create label controls, and image controls if necessary, with references to the same elements of the data model.

 

Features

A control can have references to the following elements of the data model:

·        Schema elements

Information is stored in the XML document itself.

 

·        Document properties

Information is stored in a property of the XML document.

There are changeable and write-protected document properties.

...

¡        Changeable document properties are marked with a blue symbol. You can create input fields, checkboxes, radio buttons, or combo boxes with reference to these document properties in order to set or change property values in the creation form.

¡        Write-protected document properties are marked with a black symbol. You can only create label or image controls with reference to these document properties, allowing you to display the property values on display or list forms.

 

A control must have either a reference to a schema element or to a document property.

If an input control references both a schema element and a document property, the values created are stored redundantly. This is possible for most input controls, but we recommend against it.

The HTML Editor control must have either a reference to a schema element or to a document property. If you create both references, the system ignores the reference to the document property.

 

Activities

To create a control with a reference to the data model, use Drag&Drop to pull a data model element to a space on a form (see Creating Controls).

You can also create references later on for existing controls. You do this by using Drag&Drop to pull a data model element onto the control.

In both cases, the system enters the path of the referenced element into the control property Schema Reference or Property Reference. You can change or delete the reference there if necessary.
