Shaun,

 

I had not considered it but it certainly looks a far better approach than
what I was trying.

 

I guess there are too many options to consider for a newbie flex user (and
not enough time to study them all).

 

Thanks, your help is appreciated!

 

Peter

Have you considered using the PropertyChangeEvent?

Perhaps if I am a bit less verbose.

 

1.  is having a few thousand watch listeners active on a few hundred
object realistic?
2.  Is there any way to figure out whether there is a watchlistener
active on a given property of a given object?

 

Thanks,

 

Peter

Subject: [flexcoders] ChangeWatcher question

 

Flex community,

Would someone be willing to help out with the following two questions I
have.

1. I need to keep track of a number of properties (about 20 per
object) of a large number of objects (hundreds to thousand range). I
can either use an army of ChangeWatcher instances or add some code to
the set method for each of these properties. I like the idea of using
independent changewatchers but I am not sure what the
performance/memory penalty is going to be. Has anyone some guidance?

2. Is it possible to figure out, given an object instance and a
property name, whether a ChangeWatcher is active? If so, how would
that work? Or do I have to keep track of all ChangeWatcher.watch
instances that get created.

Thanks!

Peter
