Hi All,

I am trying to track changes, including the old and new values of changed attributes of all my entities in a generic manner.

For this I want to override the propertyChange method of AttributeChangeListener Class inorder to obtain the old and new value of an attribute before it can be updated.

Looking forward to suggestions how this could be implemented.

Thanks in advance.
Tess

What are you trying to do exactly (and why?)?

The EclipseLink DescriptorEvents such as postUpdate give an ObjectChangeSet as argument (from DescriptorEvent) that contains the list of changes. The latest EclipseLink release also contains the old values.
