Another try:

I have this list of objects which I tried to compare to the changed
objects (in the transaction) via the absolute_url()-method ...

Is there a better solution to compare my list of objects with the
object I get which is affected by the transaction?
Is there any chance to compare the objects in my list with the
objects i get from the transaction so that i could realize that a
special object of my list has changed ...?


Any Ideas ...?
