There were some problems with s:selectItems in 1.1.6 (fixed in CVS) which meant that noSelectionLabel didn't work quite right.

So, in CVS, if the noSelectionLabel is selected a value of null will be passed to the entity converter, which passes this straight through to the backing bean.  I know this doesn't really answer the question, but hopefully you can work out what you want to know from here.

Btw this is an idea for a "Any" option, alternatively you could just write a custom converter from scratch...

<h:selectOneMenu id="tipoNivel" value="#{descricaoNivelList.descricaoNivel.descricaoTipoNivel}" converter="foo.converter">
  |    <f:selectItem itemLabel="Any" itemValue="any" />
  |    <s:selectItems value="#{descricaoTipoNivelList.resultList}" 
  |       var="descricaoTipoNivel"
  |       label="#{descricaoTipoNivel.descricao}"/>
  |    <ec:convertEntity /> 
  | </h:selectOneMenu>

Where you would need to write the foo.converter (make it extend EntityConverter, do something with any, then delegate to EntityConverter)
