Happy GCing

Thanks for your answer, i have now fixed it with your solution. I don't understand why it uses an array in the example?

The use of $crud->columns(array()) has been giving me trouble. When used it will give blank column fields in the grid. When i comment the $crud->columns line it will show all fields without a problem. I am not for sure but it looks like it is some problem with using it in combination with n_n relationship fields.
