The earlier ClassCastException is now history by using cayenne 1.03. That's
great.
But now I've got another one, giving the following output:
org.objectstyle.cayenne.CayenneRuntimeException: [v.1.0.3 November 16 2003]
Global exception.

Maybe the structure of my objects is important for this so I'm enclosing the
important part of the xml-file.
And here's the part of the code creating the error:
-------
.
.
.
TbAngebot aAngebot = (TbAngebot) ctxt.createAndRegisterNewObject
("TbAngebot");
aAngebot.setReaktiviertVonAlt(altesAngebot); // where altesAngebot is an
already existing Object of Type TbAngebot earlier read through the
DataContext ctxt
aAngebot.setBelongsToUser (aBrUser); // where aBrUser is an already existing
Object of Type BrUsers earlier read through the DataConext ctxt
---------------------
And the last statement will cause the error. But if I remove the line
"aAngebot.setReaktiviertVonAlt(altesAngebot);" everything works fine. But to
me this one is necessary, because I need the relation from an old TbAngebot
to a new one!
What can it be?
Thanks in advance
Michael
