How to use converters

[g00gle88]

I'm new to Forge (just started today).  I created a project based on the SAKILA database, i was able to generate entities and managedBeans with UI Scafolding for CRUD operations.  However, some enties are not converted to string properly. So I read about converters in the documentation https://docs.jboss.org/author/display/FORGE/UI+Scaffolding can someone give me a simple example how to use these converters?

Thank you.

Hi Lincoln,

Thanks for the reply.  I have already read those articles in fact I'm using the custom converts discuessed @ mkyong's site.  What I'm asking is the converter found in the managed bean that Forge creates when you issue a "scaffold from-entities" command in Forge.

Example:

In the SAKILA database, there's a table called Actor.  So using Forge I created an entity, then scaffolded it.

Here's a snippet of the converter

 public Converter getConverter()
   {
      return new Converter()
      {
         @Override
         public Object getAsObject(FacesContext context, UIComponent component, String value)
         {
            return ActorBean.this.entityManager.find(Actor.class, Long.valueOf(value));
         }
         @Override
         public String getAsString(FacesContext context, UIComponent component, Object value)
         {
            if (value == null)
            {
               return "";
            }
            return String.valueOf(((Actor) value).getActorId());
         }
      };
   }

I can I use this code in my JSF page to convert an Object to a String?

Thanks for your patience.  I've also attached the managedBean that Forge generated.

Try it see if it works. I don't see why it shouldn't.
