Description copied from interface: GUIManager

Gets an appropriate GUI context for the designated activity as configured locally for the corresponding client. This method looks for a specific context for the execution environment of the activity. If none is defined, the context for the type of the activity (for instance, a standard GUI for all web services) will be returned. If there is also no definition, a standard GUI context will be returned.
Applications using the GUI context should cast the returned instance to the appropriate implementation.

Parameters:

session - The session which is used to check for access rights on this method.

activityInstance - The activity instance for which a GUI context is to be retrieved. If a localisation is available, it will already be applied.

ebpInstanceReference - The EBP-instance reference (identifies the corresponding instance node) for which a GUI context is to be retrieved.

sessionID - The ID of the session in which the GUI context is needed.

executionContext - The context in which the component the GUI context is retrieved for is executed.

ecm - A reference to control the execution, for instance, to close the application when the user closes the GUI window of the returned GUI context.

thread - The thread, the component runs inside. The GUI context must check calls to it against this thread, to ensure thread safety.

Returns:

The context containing the appropriate GUI for displaying the user interface of an application.

Throws:

GUIContextUnavailableException - If the requested GUI context can not be created, a GUIContextUnavailableException will be thrown.
