Category ABAP Programming Error
Runtime Errors OBJECTS_OBJREF_NOT_ASSIGNED
Except. CX_SY_REF_IS_INITIAL
Web Dynpro Component WD_CCM_CONF
ABAP Program /1BCWDY/0O2TI0VKHXMB0ELNLFSW==CP
Application Component SV-SMG-CCM

Short Text
Access using a 'ZERO' object reference is not possible.

What happened?
Error in the ABAP Application Program

The current ABAP program "/1BCWDY/0O2TI0VKHXMB0ELNLFSW==CP" had to be
terminated because it has
come across a statement that unfortunately cannot be executed.

Error analysis
An exception has occurred which is explained in more detail below. The
exception is assigned to class 'CX_SY_REF_IS_INITIAL' and was not caught in
procedure
"SET_CHANGE_MODE" "(METHOD)", nor was it propagated by a RAISING clause.
Since the caller of the procedure could not have anticipated this
exception, the current program was terminated.
The reason for the exception is:
You are trying to access a component with a 'ZERO' object reference
(points to 'nothing'). Variable:
"ME->WD_THIS->IG_COMPONENTCONTROLLER~GR_ACTIVITY".
An object reference must point to an object (an instance of a class)
before it can be used to access a component. The reference has either
never been set, or it was set to 'ZERO' with a CLEAR statement.
