title: Data binding a WPF ComboBox from a ViewModel - can't change selected item
body: <p>I'll get this out of the way right off the bat... my base view model class is implementing <code>INotifyPropertyChanged</code>. Here's the scenario:</p>
  
  <p>I have a single view with a single view model. The view is a master/detail with the master being a list box of <code>Game</code> objects that I'm populating without issue. When a <code>Game</code> object is selected in the master list box, I want to populate some details in various controls. The control that's causing me problems is a combo box.</p>
  
  <p>Now, the <code>combobox</code> is being populated using a collection of <code>Team</code> objects. Each <code>Game</code> object has a "Team" object and once the <code>combobox</code> is populated, I want to select the appropriate <code>Team</code> object in the <code>combobox</code> that the <code>Game</code> object specifies.</p>
  
  <p>Now, I know this is working to some degree because if I do the same binding to a <code>textbox</code>, the right information appears (I can get the bound <code>Team</code> object to appear in the <code>textbox</code>, but I can't get it to select from the list).</p>
  
  <p>I'm seriously lost, been working on this for a few hours now. Can anyone assist?</p>
  
  <p>Edit: I have a feeling this has something to do with the object references. But wouldn't <code>SelectedValue</code> still work?</p>
