WEB UI基础八:链接跳转到标准的工单界面

接以前做的例子，用组件做了个搜索界面，明细里添加了object_id的链接：

  method GET_P_OBJECT_ID.

if me->running_in_f4_popup( ) = abap_false.
  case iv_property.
    when if_bsp_wd_model_setter_getter=>fp_fieldtype.

    when if_bsp_wd_model_setter_getter=>fp_onclick.
      rv_value = 'CLICKONLINK'.
  endcase.
endif.
  endmethod.
