deserialisation problems with derived types

["Tegethoff, Jan" <JT...@koeln.sema.slb.com>]

Hi all!
I have encountered the following problem: having used wsdl2java I have
created stub-classes to deserialize a soap response. These stubs seem to be
perfectly ok as they contain all necessary fields - however the
deserialization does not work correctly, i.e. some attribute-fields don´t
get filled (although there is no exception thrown). Those are the fields
that are generated from the attributes of the complex type
KTAbstractTopicType in the following excerpt, which is taken from the
wsdl-file. Note that this type is abstract, meaning, that these fields are
to be filled from derived types, such as 'eventType'. Could it be, that axis
does not support this behaviour? Then the idea of extending types would be
lost, so I guess, I am doing something wrong. Any suggestion will be greatly
appreciated!

PS: The wsdl is mine, so I can alter it if necessary.
