Hi Bengt,
I find that accessing the old state is possible using internal mechanics
-- but could not find a way to do it from the current API unless I expose
some internals. After a bit of deliberation, I am suggesting that we add the
following method to SaveFieldManager.
/**
* Gets the old values for the given list of fields provided they are
dirty.
* @param fields a list of field names. null implies all dirty fields.
* @return a map of old values for each given field, if they are dirty.
* The map values are a pair of objects in an array -- the 0-th element
* is the old value and the 1-st element is the current value.
*/
public Map<String, Object[]> getOldValues(String...fields)
I have tested your supplied classes with the classes you supplied.
If you do not mind being in the bleeding edge, i.e. if you can consume
OpenJPA nightly builds, then I will commit the changes.
