Is there a way for a controller object to listen for changes to an EO

Thanks,

EOEditingContext has ObjectsChangedInEditingContextNotification, but
it is on an object by object basis, not a key by key one.
You
also, if you are using wonder, check out
hasKeyChangedFromCommittedSnapshot in ERXGenericRecord. maybe listen
for the notification mentioned by chuck, then use
hasKeyChangedFromCommittedSnapshot to check the particular key you are
looking at.

Thanks. I figured there was nothing built to do exactly what I
needed, but I figured I would ask.
Do you know if there is much overhead if I implemented this in my EO
superclass even if there were no observers?

Uh, another question. :) Since I have a custom EO super-super class,
I decided to try to implement this in takeStoredValueForKey(..).
It works, although I was also trying to post the old value, and
asking for this current value at this point makes EOF not so
happy...but that's not strictly
Just a clarification, do you want to know when the value changes, even
if it's not saved to the database? Or do you just want to know if a
change is being saved? That would make a difference. ;-)

I want to know if it's being changed. I have a controller object that
will need to recalculate some values when a specific attribute changes
in the EO.

Sorry I didn't finish the first sentence. I want to know when the
value is being changed regardless of whether it's committed or not.

Why not just override the set... method to send the notification?

On Thu, Jul 9,
I was trying to make something more generic to be able to use in more
than one case and keep my Velocity template clean of that stuff.
Thanks again for all the help!

You would put it in the sub-class, in a method that overrode the super-

e.g.
public void setFoo(Number foo) {
Number oldFoo = foo();
super.setFoo(foo); // calls the generated version
// broadcast notification of this, this.editingContext(),
