Hi Kishore,
The hierarchical storage for the global variables of controllers is called the context.
Context in Webdynpro which hold the Nodes and attrubutes which can be used to bing to the UI element.
-> Link a data container that holds the data
-> The data transport between the controller can be established with mapping definition.
The variables defined in a Web Dynpro Controller context can be referenced from
other Web Dynpro controllers. This is called context mapping. This allows to
share common attributes between different controllers, so copying these attributes
between the controller contexts is not necessary.
The value of UI elements, that allow a user input, have to be connected to context
attributes of the corresponding controller. This is called data binding. Through
data binding, an automatic data transport between the UI elements and the context
attributes is established.
Combining these two concepts, the data transport between UI elements located in
different views can be defined in a purely declarative way.
Warm Regards,
Vijay
