Well it looks like you are trying to pass an entity to a String. Why does user have an areaID property? If user has a many to one M:1 relationship with area, shouldn't it just have an area property? This is assuming these are both entities. So how about something like this <h:outputLabel>areaID</h:outputLabel> | <h:selectOneMenu value="#{createuser.user.area}" id="areaID"> | <s:selectItems value="#{areas.resultList}" var="ar" label="#{ar.areaName}" hideNoSelection="true" noSelectionLabel="Please Select..."/> | <s:convertEntity /> | </h:selectOneMenu> You need to change your User entity to properly map area. Something like this | @Entity | public class User { | ... | | @JoinColumn(name="AREA_ID", referencedColumnName="AREA_ID") | @ManyToOne | private Area area; | ... | } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4089882#...
