[jboss-user] [JBoss Seam] - trouble with getting <s:convertEntity /> to work

[gothmog]

Hi,

I've read the doc and still can't get this Seam feature to work. Essentially I have something simple but I keep getting this:

My components.xml is like this


  | <core:init debug="true" jndi-pattern="mytime/#{ejbName}/local" />
  | <persistence:managed-persistence-context name="entityManager" auto-create="true"
  |                 persistence-unit-jndi-name="java:/mytimeEntityManagerFactory" />
  | 
  | 

My Page is like this:


  | <h:selectOneMenu value="#{tag.group}">
  |   <s:selectItems value="#{items.groups}" var="item" label="#{item.name}" />
  |   <s:convertEntity />
  | </h:selectOneMenu>
  | 

where tag is an entity and item.groups is a list of name value pairs

Any help is appreciated

Thanks 

Troy
