    2. CONever catch a NullPointerException but instead find the line of code that causes it, find out which variable on that line is null, and then trace back into your code to see why it has not been initialized. If you need more of our help, you'll have to tell us more and show us more including showing us your pertinent code, telling us which line is the offending line, which variable is null, and where you *think* you're initializing this variable.

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.
