title: Vaadin How to handle IndexedContainer.Property.ValueChangeEvent for specific Item or PropertyId?
body: <p>I want to handle Property.ValueChangeEvent in my IndexedContainer, when the value is changed in specific row. I expected the "event" passed as argument will supply the information what has been changed.</p>
  
  <pre><code>IndexedContainer container = new IndexedContainer();
  .
  . add container properties, insert items ...
  .
  container.addValueChangeListener(this)
  .
  .
  public void valueChange(ValueChangeEvent event) {
    // How to get itemId and another properties from the same item?
    event.getProperty(); // This returns only whole container
  }
  </code></pre>
  
  <p>The getProperty() function doesn't give me the information, from which row and column it comes. Thanks for help.<p>JH</p>
