Subject Null pointer exception at org.apache.cayenne.CayenneDataObject.addToManyTarget(CayenneDataObject.java:278)
Date Thu, 28 Aug 2008 04:52:55 GMT
Hi,

I really need help to find out what is happening here. I was adding an
object to a parent object. Below you will find all the logging output and
attached you'll also find my cayenne.xml along with the other xml files from
my project.

Thanks in advance for your help!

Ronald
