Re: Tree table

Hi,

You have to create context node with Table view first then you should change the TV super class of context node to cl_bsp_wd_context_node_tree.

This will be the parent class. You have to create class separately cl_bsp_wd_tree_node_proxy and you need to call this class in super/parent class that is cl_bsp_wd_context_node_tree.in REFRESH method

You have to call this refresh method in do_prepare_out method of IMPL class.

CALL METHOD super->refresh
    .
  DATA:   lr_root          TYPE REF TO if_bsp_wd_tree_node,
         lr_ent           TYPE REF TO cl_bsp_wd_value_node,
         lr_tree           TYPE REF TO ztreeview,
         lr_first_level_node TYPE REF TO zl_ztreevie_tree_cn02.

  DATA: lt_tree TYPE TABLE OF ztreeview,
        ls_tree TYPE ztreeview.

  lt_tree = ZL_ZTREEVIE_TREE_IMPL=>gt_tree.
  DELETE lt_tree WHERE parent_id IS NOT INITIAL.

  LOOP AT lt_tree INTO ls_tree.
    CREATE DATA lr_tree.
    CREATE OBJECT lr_ent
      EXPORTING
        iv_data_ref = lr_tree.

    lr_ent->set_properties( EXPORTING is_attributes = ls_tree ).
    lr_root = me->node_factory->get_proxy(
                                  iv_bo         = lr_ent
                                  iv_proxy_type = 'ZL_ZTREEVIE_TREE_CN02' )."this is class you should create with cl_bsp_wd_tree_node_proxy
    lr_first_level_node ?= lr_root.
      lr_root->expand_node( ).
    lr_root->node_key = add_root_node( lr_root ).

  ENDLOOP.

In child class cl_bsp_wd_tree_node_proxy put code in get_children to get children

**for first node

**for second node

same code in class ''ZL_ZTREEVIE_TREE_CN03' get_children you have to put for second node code.
