When I tried to create an AMWorkflow with -[AMWorkflow initWithContentsOfURL:error:], and passed in a nil NSURL, my program was terminated, and "*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFDictionary initWithObjects:forKeys:count:]: attempt to insert nil value at objects[0] (key: NSURL)'" was printed to the console. I expected the "error:" output-parameter to return an NSError explaining any reasons the AMWorklfow couldn't be made. Steps to Reproduce: id error = nil; AMWorkflow *workflow = [[AMWorkflow alloc] initWithContentsOfURL:nil error:&error]; NSLog(@"workflow = %@, error = %@", workflow, error); //never get here Results: I expected the "error:" output-parameter to return an NSError explaining any reasons the AMWorklfow couldn't be made. If an argument was invalid, I expected the NSError to explain this. I did not expect an NSInvalidArgumentException to be thrown.
