well no that's just the declaration of the NSMutableArray pointer, you
have to actually make it somewhere, in the initializer of your
Example_Class (and release it somewhere too)
And that variable isn't global, it's a class instance variable.
You might want to go back to the Objective-C 2.0 Programming Language
chapter about classes and initialization, that whole document is very
good and may help you sort out some ideas.

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.
