With this attribute, the linkage of the object (View component) to a Data Model (Model component) is defined. The attribute has to be defined at the View component.

The index can be an attribute that specifies the View attribute for which the Data Model shall be used. Without an index, the Data Model applies to all View attributes.

An active linkage requires at least the definition of a Data Model without index and a linking of the View attribute with a Model attribute through .dataget or .dataset.

Precedence over the usual inheritance of the attribute value takes the superseding by a set value at the closest parent object (without dialog or module).
