Hi,
I have created an webdynpro component with two tabs and simple tables in both the tabs.While I am executing the application in properly working But while I am checking in ST22 a dump is showing at the time of changing the TABS in the application.
And the dump is as follows.
Category ABAP Programming Error
Runtime Errors OBJECTS_OBJREF_NOT_ASSIGNED_NO
Except. CX_SY_REF_IS_INITIAL
ABAP Program CL_WDR_DELEGATING_VIEW========CP
Application Component BC-WD-ABA-RUN
Date and Time 20.07.2016 07:14:55
Short text
Access via 'NULL' object reference not possible.
What happened?
Error in the ABAP Application Program
The current ABAP program "CL_WDR_DELEGATING_VIEW========CP" had to be
terminated because it has
come across a statement that unfortunately cannot be executed.
What can you do?
Note down which actions and inputs caused the error.
To process the problem further, contact you SAP system
administrator.
Using Transaction ST22 for ABAP Dump Analysis, you can look
at and manage termination messages, and you can also
keep them for a long time.
Error analysis
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not
caught in
procedure "DO_EXIT" "(METHOD)", nor was it propagated by a RAISING clause.
Since the caller of the procedure could not have anticipated that the
exception would occur, the current program is terminated.
The reason for the exception is:
You attempted to use a 'NULL' object reference (points to 'nothing')
access a component.
An object reference must point to an object (an instance of a class)
before it can be used to access components.
Either the reference was never set or it was set to 'NULL' using the
CLEAR statement.

How to correct the error
Probably the only way to eliminate the error is to correct the program.

If the error occures in a non-modified SAP program, you may be able to
find an interim solution in an SAP Note.
