Maybe this is a dumb question, but I'd like to be able to access an array  
of id's (outlets) so that I can access the one of my choice depending on a  
selection made at run time....in this case I am presented a range of  
operations to perform on some data. These operations are listed in a  
PopUp. It would be easiest to use the index of the selected item to access  
an array element rather than a hard name like calc1, calc2, calc3...etc.
Am I missing something, or is this not a common type of problem?

Also, can a non-view object be palette'ized for use in IB? I'd like to be  
able to hook up one of the above calc objects using IB. ie. drag one off a  
palette into the .nib Objects well (instantiate) for graphical connection  
to other objects.

Thanks in advance.

Sounds like a job for a List (as in the List class in the Appkit).

As far as palette'izing objects goes...me thinks someone reciently uploaded an  
example of doing just that to sonata (something like ObjectPalette.tar.Z ??)
