data_reference - Data reference
The data reference is a path or name to the referenced data. There are different ways of defining data references:
- path - property name, operation or access path, which refers to a relative data source or extent
- enumeration name - name of an enumeration
- * - Inherits the data source from parent control
- empty - no value should be defined for transient data sources
- option name - option name when referring to option values
- constant value - when referring to a transient data source
Property names or path are limited to 80 characters. In order to refer to more complex data source expressions, one may refer to an operation oath (e.g. OSI function), which contains or returns a more complex path expression or evaluates the proper data source.
Notes:
Several data references require auto-positioning or initialization. In order to provide data properly, Auto-position should always be set (except for lists or trees, which shell not position on the first list item after being opened). Initialize should always be set, when values need to be created before being accessed.
