    1. COIf I try to set it as background view it only makes the cell seperators darker, I don't get why it won't work as background view, but it works as selected view?

    2. COUmm... changing `selectedBackgroundView` to `backgroundView` works just fine for me, there's probably some other issue in your code or you made some other changes to the code pasted. Maybe you're setting both the background color and the background view for the cells? Or you have several types of cells with different gradients and you're not using different cell IDs? -- these are just two problems I ran into at some point.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
