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!
PS: WO 5.3 on OS X 10.5.2 (using woswitch.sh), Eclipse 3.3, PW4
