It seems that Site Columns defined as `Type="Choice"` ignore the `Required="TRUE"` attribute when it comes to form validation on the Edit/New pages. In this sceanrio, I chose to **not** define a default value because I need the user to explicitly read and select a value...yet the form still saves when the field is left blank.

Is this expected behavior and is there a work-around? I am developing my feature in Visual Studio so whatever the solution is, it needs to be implemented in a way that can be deployed as a feature.

**More Info**

Here is my original field definition

```
<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
<Field
    ID="{5f8fe565-f627-4aed-b7b1-48e5bd2ec8ac}"
    Name="TechnicalReviewAction"
    DisplayName="Technical Review Action"
    Type="Choice"
    Required="TRUE"
    Format="Dropdown"
    FillInChoice="FALSE"
    Group="Knowledge Base Articles">
    <Default></Default>
    <CHOICES>
        <CHOICE>Publish</CHOICE>
        <CHOICE>Revise</CHOICE>
        <CHOICE>Reject</CHOICE>
    </CHOICES>
</Field>

```

I have tried it with different combinations of including/excluding empty Default element and the FillInChoice element.

Here is the definition in the content type

```
<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
<!-- Parent ContentType: Workflow Task (0x010801) -->
<ContentType ID="0x010801003EE4B5580C5846B6BE74BFC41A663388"
             Name="Technical Review Task"
             Group="KB Article"
             Description="Content Type for Technical Review Tasks in KB Workflow"
             Inherits="TRUE"
             Version="0">
    <FieldRefs>
        <FieldRef ID="{5f8fe565-f627-4aed-b7b1-48e5bd2ec8ac}"
                  Name="TechnicalReviewAction"
                  DisplayName="Action" />
        <FieldRef ID="{5f4f08ad-7f5b-4d5d-879c-50b416acae3d}"
                  Name="ActionComment" />
    </FieldRefs>
</ContentType>

```

And here is a screenshot of the form. As you can see there is no asterisks indicating a required field and of course the form saves without entering a value.
