[jboss-user] [JBoss Seam] - selectItems exception

[damatrix]

Hello,

I'm using Seam 1.1.0.GA, Ajax4JSF, Facelets and selectItems beta 1.1.1beta 4. This little bit of code on my page is giving me an exception immediately focus moves away from the selectOneMenu.

  |                                         <h:selectOneMenu id="pavilion" value="#{stand.pavilion}" required="true">
  |                                             <si:selectItems value="#{pavilionList}" var="pav" label="#{pav.title}" noSelectionLabel="-" /> 
  |                                             <a:support event="onblur" reRender="pavilionErrors"/>
  |                                         </h:selectOneMenu>  
  | 

The exception is below

and a host of others. I'll give the whole stacktrace if required. 

My components.xml has this entry
    
  |    
  |     <core:managed-persistence-context name="em" persistence-unit-jndi-name="java:/tradeWindsEntityManagerFactory"/>
  |         
  |     <selectitems:config name="mySelectItemsConfig" no-selection-label="Please Select..." entity-manager="#{em}"/>
  |    

 and my persistence unit has the entry allowing seam to manage my persistence

  | <property name="jboss.entity.manager.factory.jndi.name" value="java:/tradeWindsEntityManagerFactory"/> 
  | 

The entity manager is properly injected in my seam components using @In(create=true). Could it be something to do with A4JSF trying to validate the field? I get the feeling i'm doing something wrong but i've no idea what it is. I really need help cos i'm running out of time as this is my project work i have to submit very soon. Thanks anybody.
