[jboss-user] [JBoss Seam] - selectManyMenu and EntityHome

[ector7280]

I successfully used, the EntityHome generated by seam-gen with selectOneMenu  like this:


  | <h:selectOneMenu value="#{companyHome.instance.state}"
  |    converter="#{converters.stateConverter}">
  |   <s:selectItems value="#{stateList.resultList}" var="state"
  |      label="#{state.name}" noSelectionLabel="Please Select..."
  |     hideNoSelectionLabel="true" />
  | </h:selectOneMenu>
  | 


But when I try to use the same technique with a Collection, it throws an exception:

  | 

My question is, is it not possible to use the generated entity homes like so:


  | <h:selectOneMenu value="#{companyHome.instance.states}"  
  |    converter="#{converters.stateConverter}">
  |   <s:selectItems value="#{stateList.resultList}" var="state"
  |      label="#{state.name}" noSelectionLabel="Please Select..."
  |     hideNoSelectionLabel="true" />
  | </h:selectOneMenu>
  | 

if states is a Collection?
