    2. COYou definitely synthesizing NSString* filename? Also what is the HTTPRequest class, is this a subclass of NSURLRequest? Can you set a breakpoint before the crash and print your request object to the console? If so can you see if the filename string has been there?

    3. COHTTPRequest is a subclass of ASIHTTPRequest which is a library available from http://allseeing-i.com/ASIHTTPRequest/ Here are 2 images show the initial TrainingEntry object, and the TrainingEntry object returned after the requestFinished: is triggered.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
