Context node and TABS

19 Views

Hello Friends,

I am facing a problem, which could be very simple, and I am just not comming to the point,

Thing is I have a view which contains TABS ( 3 e.g) each tabs then furhter contains views etc.. ( all views sharing the same controller)

I have a node in controller Notif_con ( car 1:1 ) which contains a node selected_notifs ( car: 0:n ) which contains two attributes ( notif_no and notif_typ)

From 1st view i mapped the node notif_con in view's own context and set the selected_notfs attributes like following:

  CALL METHOD lo_nd_notification_detail->get_selected_elements
    EXPORTING
      including_lead_selection = ABAP_FALSE
    RECEIVING
      set                      = lt_set.

  lo_nd_notif_conv = wd_context->get_child_node( name = wd_this->wdctx_notif_conv ).
  lo_el_notif_conv = lo_nd_notif_conv->get_element(  ).
  lo_nd_selected_notif_nos = lo_nd_notif_conv->get_child_node( name = wd_this->wdctx_selected_notif_nos ).


  LOOP AT lt_set INTO ls_set.
*     retrieve selected notif no.
    CLEAR lv_notif_no.

    CALL METHOD ls_set->get_attribute
      EXPORTING
        name  = 'NOTIF_NO'
      IMPORTING
        value = ls_notif_no-notif_no.
   " APPEND ls_notif_no TO lt_notif_no.

     CALL METHOD ls_set->get_attribute
      EXPORTING
        name  = 'NOTIFICATION_TYPE'
      IMPORTING
        value = ls_notif_no-NOTIFICATION_TYPE.

    APPEND ls_notif_no TO lt_notif_no.

  ENDLOOP.

  lo_nd_selected_notif_nos->bind_table( lt_notif_no ).

  CALL METHOD lo_nd_selected_notif_nos->get_element_count
    RECEIVING
      count = size.

if I check the size it has few elements, things works fine.....

in my second view I read the node and retrieve the elements...like this:

 
lo_nd_selected_notif_nos  = wd_context->get_child_node( name = wd_this->wdctx_selected_notif_nos ).

 lo_el_selected_notif_nos = lo_nd_selected_notif_nos->get_element(  ).
 lo_el_selected_notif_nos->get_attribute(
          EXPORTING
            name =  `NOTIFI_TYP`
          IMPORTING
            value = lv_notification_type
        ).

Things works fine so far.....

Now I want to have same via third view as well, so on particular action I set the values of selected_notif ( which is here also mapped via controller ) like this:

 
   navigate from <CONTEXT> to <NOTIF_CONV> via lead selection
    lo_nd_notif_conv = wd_context->get_child_node( name = wd_this->wdctx_notif_conv ).

   navigate from <NOTIF_CONV> to <SELECTED_NOTIF_NOS> via lead selection
    lo_nd_selected_notif_nos = lo_nd_notif_conv->get_child_node( name = wd_this->wdctx_selected_notif_nos ).

    ls_selected_notif_nos-notif_no = notif_no.
    ls_selected_notif_nos-notification_type = notif_typ.
    append ls_selected_notif_nos to lt_selected_notif_nos.

    lo_nd_selected_notif_nos->bind_table( lt_selected_notif_nos ).

      CALL METHOD lo_nd_selected_notif_nos->get_element_count
    RECEIVING
      count = size.

when i check the size value is set........and I assume the controller is filled with the value and so the 2nd view..... and afterwards when i go to the 2nd view again via same coading ( paste above for the 2nd view ) the element is initial .........

I have no idea whats going on, pls note there is no refresh to node somewhere......

my question is cant i fill the context node of controller which is mapped in two views ? and access it in same view ?

hope you can provide me with nice tips ....

Regards,
