Order of callback methods

[Erdinç Kocaman <ko...@yahoo.com>]

Hi,

I have a listener object implementing LifecycleListener and it listens all events of all data objects. And also data objects has listener methods like onPreUpdate() which is set on modeler.  I want to know which listener methods are called first when any event occurred. Is the first object called when event occurred the listener object implementing LifecycleListener or data objects having preUpdate() listener methods? Or is there any order when invoking callback methods??

Thanks,

Hi,

Callbacks and listeners are invoked in order they were added to
LifecycleCallbackRegistry. *BUT *when Cayenne saves the project, listeners
are written *before* callbacks, so unless you're adding listeners/callbacks
from the code there's no actual way to change this order (you can change it
manually in *map.xml, but it will get lost next time project is saved in
modeler
