Adding new view to viewset (BP_DATA to ICCMP_BP_DETAIL)

Question

Hello Experts !
We are on CRM 7.0. I want to add the window IDNumber of component BP_DATA in the component ICCMP_BP_DETAIL.
What are the steps to follow?
I created an "usage" of the component BP_DATA in the component ICCMP_BP_DETAIL. I added the interface view BP_DATA/IdNumberWindow to the usage.
I also created a new view area ('ZIdNumberData') in the viewset ICCMP_BP_DETAIL/BuPaCreateVS. Then, I assign the view of my usage BP_DATA to this new view area.
I enhance the BuPaCreateVS.htm by adding a new line to the code like this:
   <thtmlb:gridCell columnIndex = "1"
                   rowIndex    = "3" >
    <bsp:call comp_id = "<%= controller->GET_VIEWAREA_CONTENT_ID( 'ZIdNumberData' ) %>"
              url     = "<%= controller->GET_VIEWAREA_CONTENT_URL( 'ZIdNumberData' ) %>" />
  </thtmlb:gridCell>
But when I enter the webui it's giving me a DUMP in the view BP_DATA/AccountIDNumberList, the method DO_PREPARE_OUTPUT, because the following reference is initial:
ME->VIEW_GROUP_CONTEXT
The reference ME has the following value:
Does anybody has any suggestions ?
Thank you in advance

Hi,
      Some components are meant to be used with a main component. The view group context is inherited hierarchically from parent components. Coming to your problem, assuming that the BP_DATA/AccountIDNumberList view is already enhanced, redefine the method set_view_group_context method im the IMPL class.
Put in code, something like this..
method SET_VIEW_GROUP_CONTEXT.
  IF iv_parent_context IS BOUND.
    CALL METHOD super->set_view_group_context
      EXPORTING
        iv_parent_context = iv_parent_context
        iv_first_time     = iv_first_time.
  ELSE.
    CREATE OBJECT me->view_group_context
        TYPE cl_bsp_wd_view_group_context.
  ENDIF.
endmethod.
This will clear up the immediate issue, but you will likely face more.
