Here its the error
Display Board: null
Its more than clear that there is no displayDoard where to work at,
so there is some problem with he constructor no?
Add logging to make sure this is being called:
public DisplayBoard displayBoard() {
// only do this if we haven't already created one
if (displayBoard == null) {
// since we are using the default editing context we don't want to
// just assume that the last code to use it saved all its changes.
// A revert flushes out any unwanted data before we put ours in.
session().defaultEditingContext().revert();
// as the name says - creates a new instance of DisplayBoard and
// inserts it into the default editing context
displayBoard = (DisplayBoard) EOUtilities.createAndInsertInstance(
session().defaultEditingContext(), "DisplayBoard");
}
NSLog.out.appendln("Display Board: " + displayBoard); <-- ADD THIS
return displayBoard;
}
Also: Compare your code (html, wod, java) against the completed
tutorial source and look for differences.
