Is there a Scout method (like execChangedValue()) in the AbstractRadioButtonGroup which presents the old selected value in the radio button group after/while changing the selected value?

I don't think such a method exists. For other field types I have seen/used code similar to (untested code, just wrote it from scratch):

public class MyRadioButtonGroup extends AbstractRadioButtonGroup<Integer> {

  private Integer myOldValue;

  public class RadioButton1 extends AbstractRadioButton {
    @Override
    protected Object getConfiguredRadioValue() {
      return Integer.valueOf(1);
    }
  }

  public class RadioButton2 extends AbstractRadioButton {
    @Override
    protected Object getConfiguredRadioValue() {
      return Integer.valueOf(2);
    }
  }

  @Override
  protected void execChangedValue() throws ProcessingException {
    super.execChangedValue();

    if(myOldValue > getValue()) {
      // do something
    }

    // last line of code for this method
    myOldValue = getValue();
  }
}


If the button group has an initial value (or the value is changed by other methods) of course the variable myOldValue should also be set there.

AbstractRadioButtonGroup extends from AbstractValueField so you'll have access to all methods for value setting/validation.
As an example you might use execValidateValue to compare old value to the value being set
