You can use extensibility in the web UI framework to add namespaces to
screens.
Procedure
- Select the screen in the Tree View.
- Type namespaces in the Properties
View.
- For every source and target namespace added, you need to
provide a name and description. It is recommended that the names of
all namespaces added during extensibility begin with extn_ to easily
identify them.
Note: The methods getTargetModel(),
getModel(), and setModel() can be called from the extension and would
return results from the combined model of the screen and extension.
