    s:selectItems and h:selectOneRadio?

    Brian Smith Apprentice

      Is it possible to use a s:selectItems within a h:selectOneRadio? I keep getting NPEs in the Renderkit

      <h:selectOneRadio id="streetResultsOne" value="#{intersectionStreet1}">
       <s:selectItems value="#{streetListOne}" var="streetOne"
       label="{streetOne.fullName}"
       noSelectionLabel="none">
       </s:selectItems>
       <s:convertEntity/>
      </h:selectOneRadio>

          Yes, I was getting some problems with this. The problem arises from the noSelectionLabel.

          Thanks for reminding me, I need to see if I can the RI guys to put a workaround in for this (the behaviour isn't spec breaking, just annoying).

            If I remove the noSelectionLabel, then I get null children errors (sorry, don't have exact error or stack trace at the moment) because the list is not initialized. It does not make sense in this case to initialize it with a Factory since no search has been preformed yet when the page loads. I use the noSelectionLabel to catch that error and provide a valid child to the radio menu.

            Thanks for looking into it.
