Step 5: List Binding

An app that greets is nice; an app that shows data is useful. The invoice app starts here: an internal table of invoices, bound to a UI5 list — one row template, repeated per line of the table:

CLASS zcl_app_walkthrough DEFINITION PUBLIC.
  PUBLIC SECTION.
    INTERFACES z2ui5_if_app.

    TYPES:
      BEGIN OF ty_s_invoice,
        product  TYPE string,
        supplier TYPE string,
        quantity TYPE string,
      END OF ty_s_invoice.

    DATA t_invoices TYPE STANDARD TABLE OF ty_s_invoice WITH EMPTY KEY.
ENDCLASS.

CLASS zcl_app_walkthrough IMPLEMENTATION.
  METHOD z2ui5_if_app~main.

    IF client->check_on_navigated( ).

      t_invoices = VALUE #(
          ( product = `Pineapple`    supplier = `ACME`          quantity = `21` )
          ( product = `Milk`         supplier = `Green Growers` quantity = `4`  )
          ( product = `Canned Beans` supplier = `Corner Deli`   quantity = `3`  )
          ( product = `Salad`        supplier = `Green Growers` quantity = `2`  )
          ( product = `Bread`        supplier = `Corner Deli`   quantity = `1`  ) ).

      DATA(view) = z2ui5_cl_ui5_view_builder=>factory(
          )->ele( n = `View` ns = `mvc`
              )->a( n = `xmlns`     v = `sap.m`
              )->a( n = `xmlns:mvc` v = `sap.ui.core.mvc`

              )->ele( `Shell`
                  )->ele( `Page`
                      )->a( n = `title` v = `Walkthrough - Step 5`

                      )->ele( `List`
                          )->a( n = `headerText` v = `Invoices`
                          )->a( n = `items`      v = client->_bind( t_invoices )

                          )->ele( `items`
                              )->tag( `StandardListItem`
                                  )->a( n = `title`       v = `{PRODUCT}`
                                  )->a( n = `description` v = `{SUPPLIER}`
                                  )->a( n = `info`        v = `{QUANTITY}` ).

      client->view_display( view->stringify( ) ).

    ENDIF.

  ENDMETHOD.
ENDCLASS.

One Template, Many Rows

• The table binds like the string did. client->_bind( t_invoices ) on the list's items aggregation — the same call as in Step 4, just with an internal table behind it.
• The StandardListItem is a template, not a row. UI5 clones it once per line of the table. Inside the template, {PRODUCT} is a plain UI5 binding path relative to the row — the framework maps your ABAP field names, in uppercase.
• The data is initialized in the check_on_navigated branch, right before the view. In a real app this is where your SELECT runs; the tutorial keeps demo data so the class stays self-contained.

Tables (sap.m.Table with columns and cells) bind exactly the same way — the Tables page has that variant.

Next, the rows learn to react to a click.
