How convertEntity works with the noSelectionLabel

[lmen]

Hi,

I'm using the Seam convert convertEntity code to fill a sectOneMenu,

<h:selectOneMenu id="tipoNivel"
 value="#{descricaoNivelList.descricaoNivel.descricaoTipoNivel}">
 <s:selectItems value="#{descricaoTipoNivelList.resultList}"
 var="descricaoTipoNivel"
 label="#{descricaoTipoNivel.descricao}"
 required="false"
 noSelectionLabel="Any"/>
 <ec:convertEntity />
</h:selectOneMenu>

My question is, Can the convertEntity detect that the noSelectionLabel was select by the user? (Helpful to detect if the user whats to use the field in a search criteria )

best regards,

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)

Thanks a lot for the reply. I have followed the solution to change the entity converter (returning null) because it can be applied more easily to other pages.
