      Hi,
      is it possible that i can't use SEAM EntityConverter if my environment is non-transactional?
      If I use


      I tried to use <s:convertEntity /> together with selectItems in a selectOneMenu:




      <h:selectOneMenu id="valPolSelect" 
          required="true" 
          value="#{refData.validationPolicy}" >
     <s:selectItems value="#{selectUtils.validationPolicies}" 
          var="valPol" 
          noSelectionLabel="#{messages['refData.edit.select.noValue']}"
          hideNoSelectionLabel="false"
          label="#{valPol.description}" />
     <a4j:support event="onchange" 
          reRender="valPolError" 
          ajaxSingle="true" 
          bypassUpdates="true" />
     <s:convertEntity />
</h:selectOneMenu>



      Results in a no transaction exception in the render response phase:

      As I said, my environment is non-transactional, I'm using SEAM in Tomcat without embedded JBoss.
      My components.xml contains


      <core:init debug="true" transaction-management-enabled="false" />
<transaction:no-transaction/>



      Is there a way to get around this exception or is it a limtation of SEAM entity converter?
