Just got (what I hope is) a flash of insight.

By "global to the class", do you mean that it is not an instance variable, but it defined in the implementation file?
Do you create multiple instances of your view class? If so, then initWithFrame will be called for each instance, and each time it is called, a new array will be created, and it will be assigned to your "global" variable, thereby overwriting it's previous value.

Well I found it out thinks in part to you pointing that ... obvious to anyone but me before fact ;-) ... I have a instance of the view and then also the view itself (only use one) inside a window. Well I was using the array within the view of the window but in IB linking the import method to the instance of it instead so from what I gather the instance of it and the view within the window - while derived from the same class are not treated as the same object - which would be why I was getting two different arrays...

I have since linked the import method (correctly?) to the view within the window and it works fine now.
Is it bad practice to link actions to the instances of the classes in IB or (more likely) was I just using it wrong?

Thanks so much again for all the great help and advice.
