I think... This was a bug. The add() method to support Java
collections was added to NSArray as unimplemented BUT someone forgot
to add an implmentation of it to NSMutableArray. Oops. So when you
call add() on NSMutableArrary you get this message. Wonder
correctly implements this method as does some version of WO 5.4.

um, how about using an NSMutableArray? NSArray is immutable and
does not implement add.

Hello all,
I'm trying to implement a simple web service. One of the
webservice operations takes an NSArray as parameter.
public static void foo(NSArray bar);
When the call is made, the following error pops up:

I was able to get this working by using ProjectWonder. Apparently
the NSArray class is patched
in PW and won't blow up when add(..) is called. Although we use PW
a lot anyway and thus have
a workaround, I would like to know if someone else had the problem
and eliminated it? Should I
use ordinary java collections (like List) in the parameters
instead of NSArray?
Thanks!
