Hi,
we're writing a webservice intensive app and ran into the following
problem:
when using null values in arguments to calls, we get a deserializer
excption.
It looks to me like the generic NSKeyValueCoding<String> expression it
wants to use
has no deserializer. I'm slighly amazed to see that anyway, since
we're developing
on WO53 due to the shocking mess that are webservices under WO54.
Can anyone shed some light on this?
