Hi Kaj,
this is a bug in Cayenne class generator that is used internally by
WOProject. When an EOEntity has no attributes that are class properties, it
throws this exception.In CVS version of Cayenne this is fixed already:
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/cayenne/cayenne/src/org/objec
tstyle/cayenne/wocompat/EOModelProcessor.java.diff?r1=1.6&r2=1.7
It has never been tested with WOProject though. Download the latest Cayenne
nightly build at:
http://objectstyle.org/downloads/cayenne/nightly/?M=D
and try replacing cayenne.jar in WOProject with the fresh one. If you have
problems, I will try to patch the old JAR file. Let me know.
Andrus
