Using DataScope and Provider

To set attributes for a dataScope component:

In the Design Structure Window of the desired file, select the dataScope node.
In the Property Inspector, set the following attributes for the dataScope component:
- currentData - Enter the current data object for all the children of this DataScope. In the right column, click the icon to open a dialog. In the Advanced tab, you can enter an EL syntax data binding expression or use the Bind to Data dialog to select a data source. Alternatively, you may specify the current data object in the Code Editor.
- provider - Enter the data providers that will serve child-node requests for data. In the right column, click the icon to open a dialog, then click New to enter the data names and their types in the Create Data Provider dialog. Alternatively, click the Advanced tab to enter an EL syntax data binding expression or use the Bind to Data dialog to select a data source for this complex attribute. You can add any number of data providers. Each data provider is specified by a single data element.
  If using the Create Data Provider dialog, enter a data name and select a type. Supported type values are bundle, instance, method. Then specify the class and method attributes for the data provider. For additional help, click the Help button in the dialog.
  
  Note that you can specify inline data in the Code Editor only.
- xmlns - This is the namespace of the data object. Default is http://xmlns.oracle.com/uix/ui. You may select another value in the dropdown list.

Note: To use data binding, see Data Binding a Component Attribute.
