Not compatible with the formal parameter "NEW_ITEMS"

Question

Dear,
I'm creating a very simple WD4A to just display the contents of the table.
So in the COMPONENTCONTROLLERS I created the node ZPI_USERS, according to the type of the internal table ZPI_USERS we have on the PI system.
Still in the COMPONENTCONTROLLER under methods I'm trying to implement this code in the 'wddoinit' event:
METHOD wddoinit.
  DATA: lt_users    TYPE zpi_users,
        node_users  TYPE wd_this->element_users,
        lo_nd_users TYPE REF TO if_wd_context_node,
        lo_el_users TYPE REF TO if_wd_context_element.
* navigate from <CONTEXT> to <USERS> via lead selection
  lo_nd_users = wd_context->get_child_node( name = wd_this->wdctx_users ).
  SELECT * FROM zpi_users
           INTO lt_users.
    lo_nd_users->bind_table( new_items = lt_users ).
  ENDMETHOD.
On trying to activate I get the following error :
Web Dynpro Comp. / Intf. ZPI_DISPLAY_MONIUSERS,Web Dynpro Component Controller COMPONENTCONTROLLER
Method WDDOINIT
"LT_USERS" is not type-compatible with formal parameter "NEW_ITEMS".
I know I'm overseeing something very simple, though I get the feeling I'm running in circles. Again: the only thing I want to do is show an internal SAP table through a Web Dynpro.
Kind regards,

Hi,
You have declared
DATA: lt_users    TYPE zpi_users,
This means that you are declaring a work area and not an internal table, whereas while binding we need to pass an internal table.
Declare your table as follow,
DATA: lt_users    TYPE TABLE OF zpi_users.
" modify your select
    SELECT *
      FROM zpi_users
      INTO TABLE lt_users.
Hope this helps!
