[jboss-user] [JBoss Seam] - Re: Adding/Persisting A Record Problem...

[johnurban]

Getting closer. I removed the room dropdown lookup logic from the jsp and it complianed about calling personEdtor.poo. I changed it back to personEditor.create and it added the record. So it appears there is something that occurs when the dropdown room lookup logic is inserted in the jsf:

JSF:


  |          <h:selectOneMenu value="#{roomFinder.example}" converter="org.jboss.seam.EntityConverter">
  |    			<f:selectItems value="#{roomListByOrganization}" />
  | 		 </h:selectOneMenu> 
  | 
  | 

RoomFinderBean
