Experts,
I am getting following error for web dynpro application intermittently, please find following error log:
What happened?
Error in the ABAP Application Program
The current ABAP program "CL_SALV_WD_C_TABLE_V_TABLE====CP" had to be
terminated because it has
come across a statement that unfortunately cannot be executed.
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 "IF_SALV_WD_COMP_TABLE_DATA_MAP~MAP_TO_RESULT_CHANGES" "(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.
Information on where terminated
Termination occurred in the ABAP program "CL_SALV_WD_C_TABLE_V_TABLE====CP" -
in "IF_SALV_WD_COMP_TABLE_DATA_MAP~MAP_TO_RESULT_CHANGES".
The main program was "SAPMHTTP ".
In the source code you have the termination point in line 168
of the (Include) program "CL_SALV_WD_C_TABLE_V_TABLE====CM080".
The termination is caused because exception "CX_SY_REF_IS_INITIAL" occurred in
procedure "IF_SALV_WD_COMP_TABLE_DATA_MAP~MAP_TO_RESULT_CHANGES" "(METHOD)",
but it was neither handled locally nor declared
in the RAISING clause of its signature.
The procedure is in program "CL_SALV_WD_C_TABLE_V_TABLE====CP "; its source
code begins in line
1 of the (Include program "CL_SALV_WD_C_TABLE_V_TABLE====CM080 ".

Please help us on what could be the reason behind this?
