public DataObject asynchronousServiceHandle(java.lang.String requestTag,
                                            DataObject data)

                                            MethodException

This abstract method is used to generically handle the results from any asynchronous service that a widget may support. An asynchronous service will trigger this method to be called when the object implementing this interface calls the remote asynchronous service.

Parameters:

requestTag - The requestTag used to identify the service request

data - DataObject containing the data for service execution

Returns:

DataObject containing any directives to the service that was executed

Throws:

InvalidMethodException - if the specified callback can't be found

MethodException - is thrown if the specified callback can not be executed successfully
