title: Using Entity Framework, allow null attribute not updating in model
body: <p>I'm using Entity Framework in Visual Studio and am working with an existing table and corresponding model. I have changed the table to allow null values for some attributes. However, when I try to update my model, it doesn't pick up the change.</p>
  
  <p>I'm going into the model designer, right clicking my model, and selecting "Update Model from Database". In the next window, I see my table in the Refresh tab, but selecting it still leaves the "Next" button below grayed out. I can only click "Finish".</p>
  
  <p>Any ideas on why this is?</p>
  
  <p>I'm using Entity Framework 4 (I think), MS Visual Web Developer 2010, and working with an ASP.Net 3.5 MVC 2 application.</p>
