Force server round trip

[Former Member]

Hi All,

I have a requirement where I have two fields. One is drop-down and other is input field(mandatory field). Based on the dropdown value input field gets populated automatically. But error message still shown in the message bar since it is an mandatory field. User need to press enter to remove this error.

I am trying to use server round trip in p_method of input field using fp_server_name but the property server name is not set for input field. How can I remove this error message without pressing Enter and is there any other way how can I trigger server round trip.

Thanks

Hi Lalit,

You can try to delete this particular message based on the message number if your input filed is having a value in do_prepare_output( ) of the view.

Hi Lalit,

Put the following code in the GET_P_XXXX method of the drop-down field attribute:

   CASE iv_property.
*****

     WHEN IF_BSP_WD_MODEL_SETTER_GETTER=>FP_SERVER_EVENT.

       rv_value = 'CHANGE_EVENT'.

   ENDCASE.

Thanks,

Hi Lalit,

In GET_P_XXX method use fp_server_event OR fp_on_click instead of  fp_server_name to trigger round trip on select of dropdown.

CASE iv_property.

     WHEN if_bsp_wd_model_setter_getter=>fp_fieldtype.

      rv_value = cl_bsp_dlc_view_descriptor=>field_type_picklist.

     WHEN if_bsp_wd_model_setter_getter=>fp_server_event.

      rv_value = 'Dummy_Event'.

  ENDCASE.

Hi Rajarama,

I am already using fp_server_event but ServerEvent value is never set in p_XXX method. I am using it in the p_xxx method of input field not in dropdown.

I need to trigger the round trip when the input field is set on the base fo dropdown selection of another field.

Thanks

Hi Lalit,

Are you calling any event on selection of value in Dropdown? When you are setting the values for inputfield.?

  Event that you defined in GET_P of input field will not work.

Hi Rajarama,

Value of the field is getting populated through categorization schemas and before that mandory field check has been processed. I am calling event in get_p method of input field.

Is there any other way we can achieve this?

Hi Lalit,

  If the input field is filled ,Can you delete the message in DO_VALIDATE_INPUT or DO_FINISH_INPUT?

  Sorry I don't know any other way.
