[jboss-user] [JBoss Seam] - Validating errors in JBoss Seam using FacesMessages

[lara]

Hi,

I am using jboss-seam-1.2.0.PATCH1 and I am try to display a message for unique names. I mean I am adding a client and the name should always be unique, I added the following in the ClientHome.java class:


  | @Override
  | 	public String persist() {
  | 		try {			
  | 		    return super.persist();
  | 		    } 
  | 		catch(Exception e)
  | 		    {
  | 		     if (e instanceof javax.persistence.EntityExistsException) {	
  | 		     FacesMessages.instance().add("name", "Client Name should be unique");	
  | 		    }
  | 		    return null;
  | 		    }
  | 	}
  | 


The problem is that the error is catched and I have no bug in the application but the message is not displayed and I am getting the following on the server:


  | ERROR [STDERR] com.sun.faces.lifecycle.RenderResponsePhase execute
  | INFO: WARNING: FacesMessage(s) have been enqueued, but may not have been displayed.
  | 


How can I solve this issue?
Any help is appreciated!

Best Regards,
