Column headers hiding

[fishersystems]

I've only been using the ExtJs for a couple of months and all was going well until I wanted a grid to display data that wasn't sorted as it only had one row of data.

I've discover that (for me atleast) that if I don't provide a default sort field the column headers of the grid get hidden after rendering.

Is there something tricky that I need to do or is this a bug?

Thanks
