> When using the <s:convertEntity /> tag along with a component such as primefaces autocomplete the EntityConverter will throw a NumberFormatException when it is passed an empty string as JSF is prone to do.
> <pf:autoComplete 
>        id="fromUserAC" 
>        value="#{emailTemplateData.fromUser}"
>        widgetVar="fromUserAC" 
>        forceSelection="true" 
>        completeMethod="#{userLists.searchUsers}" 
>        var="_user" 
>        itemValue="#{_user}" 
>        itemLabel="#{_user.name}" 
>        selectListener="#{emailTemplateDataAddUtil.selectFromUser}" 
>        onSelectUpdate="fromUser" 
>        required="true">
>    <s:convertEntity />
> </pf:autoComplete>
> The solution is to add a .isEmpty() check to the converter.
