title: Prism/MEF Load different data in same view (non shared)
body: <p>I create a WPF application using Prism and MEF.
  In one module, I have a Customer list. To edit customers data, I have one View "EditCustomer.xaml".</p>
  
  <p>A user can edit many customers, so he can open many different instances of EditCustomer.xaml.</p>
  
  <p>Here's code of the ViewModel :</p>
  
  <pre><code>[Export(typeof(EditCustomerViewModel))]
  [PartCreationPolicy(CreationPolicy.NonShared)]
  public class EditCustomerViewModel : ViewModelBase
  </code></pre>
  
  <p>And the code behing of XAML :</p>
  
  <pre><code>[Export(typeof(EditCustomerView))]
  [PartCreationPolicy(CreationPolicy.NonShared)]
  public partial class EditCustomerView : RadPane
  {
      public EditCustomerView()
      {
          InitializeComponent();
      }
  
      [Import(typeof(EditCustomerView))]
      public object ViewModel
      {
          get
          {
              return this.DataContext;
          }
          set
          {
              this.DataContext = value;
          }
      }
  }
  </code></pre>
  
  <p>The "CreationPolicy.NonShared" property works perfectly, but when I want to bind the customers data, every views are binded with the last values.
  I only want to load and display the latest data in the new view instance.</p>
  
  <p>How can it be possible? Maybe I forgot something ?</p>
  
  <p>In advance, thanks for your help.</p>
  
  <p>Regards.</p>
