Cannot insert the value NULL into column 'Value', table 'dbo.MetaDictionary'

In EPiCommerce I am trying to use the Dictionary Property Values.
On a variant I added the following property:

[Display(Name = "Product color", Description = "Product color", GroupName = SystemTabNames.Content, Order = 113)]
[BackingType(typeof(PropertyDictionarySingle))]
public virtual string ProductColor { get; set; }

This makes ProductColor available in commerce settings. When I try to add a value (im sure it's not empty) nothing happens. In the log file I see the following:

2016-09-30 15:06:30,423 [540] ERROR EPiServer.Global: 1.2.5 Unhandled exception in ASP.NET

Am I missing something or is this a bug?

I just tried your code and it works perfectly normal. I would suggest you to:

- Try to make sure the mdpsp_sys_AddMetaDictionary stored procedure is not modified

- Run Sql profiler to see which value is sent to database when that SP is called.
