Changing attribut of select option parameter by radio button

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
