>      Project: MyFaces

>   Components: Tomahawk
>     Versions: Nightly, 1.1.0
>  Environment: tomcat 5.5.7, java 1.5, linux 2.6.13

>
> When I create a HtmlSelectBooleanCheckbox and set displayValueOnly to true, an exception
is raised during the rendering phase. During encodeEnd() HtmlRendererUtils.renderDisplayValueOnlyForSelects()
is called.
> The following snippet causes the problems:
>         
> if (uiComponent instanceof UISelectMany) {
>   isSelectOne = false;
>   selectItemList = RendererUtils.getSelectItemList((UISelectMany) uiComponent);
>   converter = findUISelectManyConverterFailsafe(facesContext, uiComponent);
> } else {
>   isSelectOne = true;
>   selectItemList = RendererUtils.getSelectItemList((UISelectOne) uiComponent);
>   converter = findUIOutputConverterFailSafe(facesContext, uiComponent);
> }
> Since the HtmlSelectBooleanCheckbox is derived neither from UISelectMany nor from UISelectOne
but from UISelectBoolean, the cast to UISelectOne fails.
