I have an MVC3 Project in C#.Net. I have Object1 with a list of Object2...

```
    //navigation Property(s)
    public virtual ICollection<Object2> Object2s { get; set; }

```

Object2 has an Object1 property and an Object1\_Id property

```
    public int Object1_Id { get; set; }
    public virtual Object1 Object1 { get; set; }

```

When I run the Index View for Object2 I get the message "Invalid column name 'Object1\_Id1'". Weird....it's looking for an automated column. When I remove the Object1\_Id from Object2, it does fine until I go to Save in the Create View. It then throws an error message:

```
{"Cannot insert the value NULL into column 'Object1_Id', table 'dbo.Object2'; column does not allow nulls. INSERT fails.\r\nThe statement has been terminated."}

```

I'm sure I'm just missing an easy step. Any ideas?
