New to the forums and could use a hand. I am completely stuck, and not sure what to do at this point.
I keep getting "TRACE: <at java.lang.IndexOutOfBoundsException: Empty field: 106>, Exception caught in Display class java.lang.IndexOutOfBoundsException: Empty field: 106" during run-time when the method, displayList() is called (currently on a softkey for testing purposes).
The Netbeans output window mentions this line, "String [] nameValues = c.getStringArray(Contact.NAME, 0);, located in displayList(). Maybe there is something wrong with this, or Netbeans is just pointing to it for the heck of it =P.
