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!
