lookup-failure

[Jens Mayer <je...@gmx.de>]

Hi,

I'm wondering about an error message:
"Can't perform lookup. There is more than one ObjEntity mapped to class 
TmpAttredit"

This is the code (as simple as possible):

DataContext dataCtx = ....
SelectQuery query = new SelectQuery(TmpAttredit.class);
List result = dataCtx.performQuery(query);

The Mapping in the Modeler seems to be ok - nothing unusual here. The 
exception is only firing for 2 of my 8 ObjEntity-classes.

what does this message means?

I'm using cayenne 2.0.2 with jdk 1.5.0_10 and Oracle 10.2.0.3.0

Thanks in advance

Jens

I'd guess the error means just what it says.   You've got two
ObjEntities mapped to a class named TmpAttredit.

Try posting your datamap if you can't locate the problem yourself (but
a text search for TmpAttredit on the xml file should find the
problem).
