[castor-dev] Type for IDREF Object

[Thomas Louis]

Hello,

is it necessary to have the type java.lang.Object for an Object that is
referred by IDREF. I tired to give use the Class that really should be the
type of the referred Object, but it doesn't work. The exception is:
java.lang.IllegalArgumentException: Type conversion error: could not set
value of kategorie(com.gastroeasy.xml.Kategorie) with value of type
java.lang.String

If you use java.lang.Object instead of com.gastroeasy.xml.Kategorie
everything works fine, but kategorie is an Object and not a Kategorie.

Can you help me?

Thx,
Thomas
