How to populate context node of component controller

Question

Dear People,
Is there any way i could access my custom context node of component controller in the context node class of my custom controller.
I am navigating from one component to another, Upon initial launch everything is working fine, however if i go to home page and come back. the assignment block is coming empty.
In WD_USAGE_INITIALIZE i m binding my custom controllers context node with the component controller's context node of the other component and it works fine when i load the UI. however if i go to home page and come back. the assignment block is coming empty.
Following code is in method of DO_VIEW_INIT_ON_ACTIVATION of the other componenet.
METHOD do_view_init_on_activation.
  DATA:   lv_btstatus_parent TYPE REF TO cl_crm_bol_entity,
        lv_comp_ctrl      TYPE REF TO cl_btstatus_bspwdcomponen_impl.
  CONSTANTS:
        lc_us_header      TYPE crmt_relation_name VALUE 'BTStatusHUserAll',
        lc_us_item        TYPE crmt_relation_name VALUE 'BTStatusIUserAll'.
  lv_comp_ctrl ?= me->comp_controller.
check if relationname has been passed from outside
    gc_relation_name = lv_comp_ctrl->get_relation_name( ).
  IF gc_relation_name IS INITIAL.
  check type of parent to determine relationname
    *lv_btstatus_parent ?= lv_comp_ctrl->typed_context->btstatusparent->collection_wrapper->get_current( ).*
   check lv_btstatus_parent is bound.
    CASE lv_btstatus_parent->get_name( ).
        WHEN 'BTStatusH'.
          gc_relation_name = lc_us_header.
        WHEN 'BTStatusI'.
          gc_relation_name = lc_us_item.
    ENDCASE.
  ENDIF.
CALL METHOD super->do_view_init_on_activation.
ENDMETHOD.
Here lv_btstatus_parent is bound during initial launch, however after navigating back to the same page, its blank leading to exception.
any suggestions would be helpful.
