New Post: Grid Groupable column with null value, does not work

While preparing grid data we used custom header using "MakeHeader", for example:

return new GroupHeader

                    {
                        Content = name
                    };

Where sometime "name" value could go null, which is why it was failing.

For your second question, we have used earlier version (4.5.0.0) of "Omu.AwesomeMvc" assembly where i guess ".Mod" was not available and it was generating ids without doing anything.
We tried referencing latest library but due to some conflicts we reverted it back.
