HtmlRadioRendererBase calls converter method getAsString() not with the object, but with the string version when an validation error occured

If you have a <h:selectOneRadio> component with some SelectItems and you select an item, submit it and an validation error occurs, HtmlRadioRendererBase calls org.apache.myfaces.shared_impl.renderkit.RendererUtils.getConvertedStringValue() with the submitted value, which is not converted an therefore already the string version of the SelectItem. So the provided converter tries to convert the string version to the string version, which can end in strange behaviour.
