Dynamic Browse format cell..

I wonder... Why could it be that following code don't work as spected?

CREATE BROWSE hBrowse
        ASSIGN
        X = 17
        Y = 63
        WIDTH = 90
        DOWN = 14
        FRAME = FRAME {&frame-name}:handle
        READ-ONLY  = YES
        SENSITIVE = TRUE
        ROW-MARKERS = TRUE
        SEPARATORS = TRUE
        FIT-LAST-COLUMN = TRUE
        FONT = 1
        TRIGGERS:
            ON DEFAULT-ACTION
                DO:
                    IF AVAILABLE(ttClienteNombre) THEN
                    DO:
                        ASSIGN
                            pSeleccion = ttClienteNombre.cliente.
                        APPLY "GO":U TO FRAME {&FRAME-NAME}.
                    END.
                END.
            ON ROW-DISPLAY
                DO:
                    hBrowse:GET-BROWSE-COLUMN(1):FORMAT = "X(40)".
                    hBrowse:GET-BROWSE-COLUMN(2):FORMAT = "X(15)".
                    hBrowse:GET-BROWSE-COLUMN(2):FORMAT = "X(16)".
                END.
        END TRIGGERS.


    CREATE QUERY hQuery.
    hQuery:SET-BUFFERS(BUFFER ttClienteNombre:handle).

    hQuery:QUERY-PREPARE(cBaseQuery).

    hQuery:QUERY-OPEN ().

    hBrowse:QUERY = hQuery.

    hColumn = hBrowse:ADD-LIKE-COLUMN ("ttClienteNombre.Nombre").
    hColumn = hBrowse:ADD-LIKE-COLUMN ("ttClienteNombre.RFC").
    hColumn = hBrowse:ADD-LIKE-COLUMN ("ttClienteNombre.Cliente").
    hBrowse:GET-BROWSE-COLUMN(1):Width = 35.
    hBrowse:GET-BROWSE-COLUMN(2):Width = 15.
    hBrowse:GET-BROWSE-COLUMN(3):Width = 10.

First, customer name won't shows full name as contained on record, it uses "X(8)", alsto RFC column has same problem.

Width of fields apparently is correct, but not format...

Thanks!
