Hivemind problem with tapestry 4

[Rodnei Couto]

Hi list,

I'm migrating my aplication from tapestry 3 to tapestry 4. I made this
hivemind helloWorld example with tapestry to learn, but this didn't
work.

The version of hivemind is 1.1.1.

Somebody can help me?

The exception is:

org.apache.hivemind.ApplicationRuntimeException
Error at context:/WEB-INF/Home.page, line 9, column 68: Error adding
property valor to class tapestryTest.Pagina: The value obtained using
locator 'service:examples.HelloWorld' (<SingletonProxy for
examples.HelloWorld(com.helloworld.exampple.HelloWorld)>) is not
compatible with the existing property (of type
com.helloworld.exampple.HelloWorld).


HelloWorld Interface:

package com.helloworld.exampple;
public interface HelloWorld {
   public String getHelloWorld();
}

HelloWorldImp Class:

package com.helloworld.exampple;
public class HelloWorldImp implements HelloWorld {
   public String getHelloWorld() {
      return "Hello World";
   }
}

hivemind.xml

<?xml version="1.0"?>
<module id="examples" version="1.0.0" package="com.helloworld.exampple">
   <service-point id="HelloWorld">
       <invoke-factory>
           <construct class="HelloWorldImp"/>
       </invoke-factory>
   </service-point>
</module>

Home.page

<page-specification class="tapestryTest.Pagina">
   <inject property="valor" object="service:examples.HelloWorld"/>
</page-specification>

Home.java

public abstract class Pagina extends BasePage {
  public abstract HelloWorld getValor();
  public String getString(){
       Object valor = getValor();
       return getValor().getHelloWorld();
   }
}
