I have, one class, this class has one proprerty: data. I'm writing this for uploading imagens.

Local interface
import javax.ejb.Local;
  | 
  | @Local
  | public interface Upload {  
  |     
  | 	//seam-gen method
  | 	public void upload();  
  | 	
  | 	public byte[] getData();
  | 	
  | 	public void setData(byte[] data);
  | 	
  | 	public void finalizar();
  | 	
  |     //add additional interface methods here
  | }

Class that implements the interface

  | import org.jboss.seam.annotations.Name;
  | import org.jboss.seam.annotations.In;
  | import org.jboss.seam.annotations.Logger;
  | import org.jboss.seam.annotations.Destroy;
  | import org.jboss.seam.annotations.Scope;
  | import org.jboss.seam.ScopeType;
  | import org.jboss.seam.log.Log;
  | import org.jboss.seam.faces.FacesMessages;
  | import javax.ejb.*;
  | 
  | @Stateful
  | @Name("upload")
  | @Scope(ScopeType.SESSION)
  | public class UploadBean implements Upload {
  | 	
  |     @Logger private Log log;
  | 	
  |     @In FacesMessages facesMessages;
  |     
  |     private byte[] data;
  |     
  |     public byte[] getData() {
  | 		return data;
  | 	}
  | 
  | 	public void setData(byte[] data) {
  | 		this.data = data;
  | 	}
  | 	
  | 
  | 	public void upload()
  |     {
  |         //implement your business logic here
  |         log.info("upload.upload() action called");
  |         facesMessages.add("upload");
  |     }
  | 	
  | 	@Remove @Destroy
  | 	public void finalizar(){
  | 		
  | 		
  | 	}
  | }
  | 

The lines are 

  |    <h:form>
  |     	<s:fileUpload data="#{upload.data}" accept="images/*"/>
  |     	<h:commandButton action="#{upload.upload}" value="carregar"/>
  |     </h:form>
  | 

When I click on the comand button, an error happens:
javax.el.PropertyNotFoundException: /home.xhtml @28,43 value="#{upload.data}": Target Unreachable, identifier 'upload' resolved to null

Every change in the class or xhtml doesn't have any effects in the server, I've to restart the server many times before some changes go to the server.

Other time I get the same error and this error disappear mysteriously.

Anyone has an idea about this?
