Field validation with popup message

[Former Member]

Hello,

I have a form for saving email addresses. In this form you have to type your email in a input-field an then you must retype it in another input-field. After clicking a button the email address is stored ....

How can i display a PopUp (or something like that) when the two addresses are different? Further the navigation to the next view, where I store the address should stopped and the user have to check his data.

Thanks

Hi Chris,

The standard method is to display a message in the message area.

You can do this in WDDOBEFOREACTION:

  data lo_api_controller type ref to if_wd_view_controller.
  data lo_action         type ref to if_wd_action.

  lo_api_controller = wd_this->wd_get_api( ).
  lo_action = lo_api_controller->get_current_action( ).

  if lo_action is bound.
    case lo_action->name.
      when '...'.
*    TODO: check whether both attributes are identical.
*    if not, use the code wizard to report an error message 
*    REPORT_ATTRIBUTE_ERROR_MESSAGE and
*    enter the element reference and the attribute name of the second field.
    endcase.
  endif.

Then the action handler will not be called in case of an error.
