How to refresh task hierarchy after creating some tasks programmatically?

[jj1]

Hi,

How can I get the left task hierarchy (or tree) get refreshed with new tasks which are created by myself programmatically in cPro 4.5?

I created some tasks under the exising task but they are not shown in the left task hierarchy automatically, only shown after I refresh the page manually or by re-entering the project again.

Thanks in advance for your help. Any suggestion would be helpful.

Best regards,

Beiyang

Code below notifies the dpr_tree webdynpro component of the creation of a task.

The dpr_tree component will receive the changes and upate itself in its on_update method.

(Please be aware that the parents of the newly created task to the root node should already be loaded in the tree)

The important method is lr_api_chg_hndlr->NOTIFY_CREATE(

  data lv_objtype type cgpl_object_type.
  data lr_chg_mgr type ref to cl_dpr_ui_change_manager.

        lv_bo_node_name TYPE string,
        lv_bo_name      type string.
  DATA: lv_api_struc TYPE string.

  data lr_api_chg_hndlr type ref to IF_DPR_CHANGE_HANDLER.

  data lr_cx_root type ref to cx_root.


  TRY .

    IF ir_common is INITIAL or iv_guid is INITIAL.
      return.
    ENDIF.

    lr_chg_mgr = cl_dpr_ui_change_manager=>get_instance( ).
    lv_obj_type = ir_common->get_object_type( ).
    lr_api_chg_hndlr = CL_DPR_API_CHANGE_HANDLER=>get_instance( ).

    CALL METHOD cl_dpr_ui_services=>get_api_data_for_object_type

            ev_api_structure  = lv_api_struc
