Active component must exist when getting interface controller

[Former Member]

HI,

when I try t call interface controller from component controller I am getting this exception.

What might be the problem?

com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: ComponentUsage(NetworkScheduleDAInterface): Active component must exist when getting interface controller. (Hint: Have you forgotten to create it with createComponent()? Should the lifecycle control of the component usage be "createOnDemand"?

Hi Karthick,

I think while you have created the Component Usage, you selected the "Lifecycle" as "manual".

If it correct. If yes then you need to create the component usage yourself in the code.
