Changing attribut of select option parameter by radio button

[michael_habermueller]

Hello,

on a wd4abap view we have a radio button group and

some select options which are contained in an embedded view of type

WDR_SELECT_OPTIONS component.

The radio button group and the select-options works fine except of the following functionality.

Depending on the value of a radio button group we want to set the obligatory parameter of a select option to true / false.

To Do this, we implement an action

ONACTIONDO_INPUT_PREPARE

which is bound to the onselect attribute of the radio button group.

The result is that a dump in the wdr-select-option component occurs.

Code and Dump is stated below.

Is there a better way to implement this logic or is it an error in the framework ?

Best regards

Michael

Hi Abhi,

thank you for your helpful answer.

The result is that I do not have the dump anymore.

Unfortunately, the screen is not updated.

The field is still displayed as an obligatory parameter.

One aspect I do find astonishing.

To get the i_result table I first tried

      CALL METHOD lv_sel_opt->get_selection_field
        EXPORTING
          i_id                      = 'PARTNER'
        IMPORTING
*    e_within_block            = e_within_block
*    e_description             = e_description
*    e_is_auto_description     = e_is_auto_description
          et_result                 = et_result

But with this I do net get any result. What I do see in the debugger, is that it jumps into the interface definition, but is not performing any code of the implementing class.

To get the result table I used

      CALL METHOD lv_sel_opt->get_range_table_of_sel_field
        EXPORTING
          i_id           = 'PARTNER'
        RECEIVING
          rt_range_table = et_result.

With this I do get the result and can pass it to the update method. In debugger I do see how get_range_table and the update method is performing their task.But unfortunately, that does not update the screen.

Strange.

Best regards

Michael

Strange, seems to be problem with the component WDR_SELECT_OPTIONS, It is not reflecting the change while rendering, but it is functioning correctly though it is showing mandatory once the method gets executed it is not mandatory any more.

You can delete the selcttion field and add it again, though a poor idea, can be work it out for now

pass IT_RESULT parameter to the method call UPD_SELECTION_FIELD
