You declared a pointer to an instance of NSMutableArray as an instance
variable of Example_Class (its in no way global) there, but you didn't
create an instance of NSMutableArray. Did you do something like this
at some point?
globalVariable = [[NSMutableArray alloc] init];

Whoops, sorry I didn't put that in...
@interface Example_Class : NSObject {
IBOutlet NSTableView *tableView;
NSMutableArray *globalVariable;

We *can't* assume anything. You left out the most relevant part of
your code: how are you creating "globalVariable"?

Hi everyone:
I am having a strange problem with NSMutableArray which is that it
doesn't
seem to work with addObjectsFromArray. I try setting this for a
"global
variable" (forget what they are called in Cocoa) and it just
returned null.
Here is my code (assuming that global Variable is the global
variable which
is a NSMutable Array):
NSArray *testing = [NSArray arrayWithObjects:@"testing", @"testing",
nil];
[globalVariable addObjectsFromArray:testing];
Thanks for any help.
