    1. COOn what line do you get the error? Is it a compile error? In your example `options` is a local variable so if you try to access it somewhere else it won't work. Also note that you keep overwriting its content at each loop which is probably not what you intended.

    2. COI think he must be getting compile time error.. in that case just create as global variable as `String[][] options =null;`.. if its not compile time.. then post log traces..

    3. COI get the error after I insert something like: String test = options[0][0]; I guess it's not a compile error, as I haven't compiled anything yet

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.
