I expect your problem is one of perception. WebServices are not a WO only,
or even Java only, technology. As such they do not return technology
specific data types. If your service actually did return instances of
EOEnterpriseObject, what would someone using J2EE, or .NET, or whatever do
with them? Where is the J2EE or .NET, or PHP definition of the
EOEnterpriseObject class? I don't know either.
While far from a WebServices guru, I'm pretty sure that what gets returned
is a dictionary, hashmap, or somesuch. You can NOT cast this to an eo
object, nor otherwise coerce it to an eo object in any other reasonable
way. You can probably use this directly with KVC to get at values. As
WOBuilder will not know the key values in advance you will have to type
them in manually. You might need to provide a wrapper method to translate
between Object[] and NSArray for a WORepetition.

P.S. WORepetition not WORepeater
