Sitecore FieldRenderer Control and OverrideFieldValue

The FieldRenderer Control (Sitecore.Web.UI.WebControls.FieldRenderer) has a method called OverrideFieldValue that takes a string and is supposed to be shown instead of the real fields value, but it doesn't work.

It seems a fix would be to add in a new pipline that accounts for this preset value.

Here's the code:

public class GetOverriddenFieldValue  
{  
    // Methods  
    public void Process(RenderFieldArgs args)  
    {  
        Assert.ArgumentNotNull(args, "args");  

        if (!string.IsNullOrEmpty(args.FieldValue))  
            args.Result.FirstPart = args.FieldValue;  
        else  
            args.Result.FirstPart = args.Item[args.FieldName];  
    }  
}

You then need to drop this in the Pipline in the web.config file so that we can modify the value on the way out.

Look for the following node:

<processor type="Sitecore.Pipelines.RenderField.AddBeforeAndAfterValues, Sitecore.Kernel" />

Now add the following above that:

<processor type="Your.Namespace.GetOverriddenFieldValue, Your.Assembly" />

The bug has been logged with Sitecore so hopefully they release an official patch.
