for the record, the two use cases for making a delegate are
1) you want to compute what object to latch onto programmatically and
2) you want to latch onto something that is not yet created at the
handler init phase.
don't see any other use, although the two above are obviously important

you are exactly right. I want to make some operations when the
netconnection successful event is fired. Actually i m trying to get
the shared object on the server side, so at first i need a
netconnection instance to do that. ThatS why i thought that i should
try delegates. I havenT used delegates before, but i thought that this
is the just one solution to handle the operations depend on the
related event.
The method you said, using an attribute in the connection class seems
the better way. Till now, i havenT needed the delegates. I hope using
connection status attribute in the connection class will fix the problem.
I m going to post back the results here of course.
Thanks for the reply J

I can tackle it. let's see; i'd write the following, after an
introduction (all code is untested and represents a pattern, adapt
it as you will)
Your problem: You want to do is send a "connection successful"
event that you can catch, signaling that a method is to be called
to continue using the connection. You seem to be trying to do it
by setting up the delegate manually, when i think, looking at your
code, that you have hooks to fire events on laszlo nodes that can
communicate this state change.
Solution: An event is anytime you use x.setAttribute() by the way
- that's what it does, makes sure that handlers are fired. That
said, if you declare an attribute of any laszlo node and in your
code, when you have success on your net connection, you say
"somenode.setAttribute('success, true);" then in another node you
can say, <handler name="onfoo" reference="somenode">...</handler>
and in that code you can then do what ever other steps are
required to use the connection.
Further thought if i'm wrong: can you say why it is you decided to
use manual delegates? it might make things clearer for me, i've
not used the net connection code you have there but make guesses.

hi
when i try do use the delegate such like :
if( typeof this.del == "undefined" ) {
this.del = new LzDelegate(this, "connect('chat', conn,
true)" );
} this.del.register(conn,
"netStatusHandler('NetConnection.Connect.Success')" );
}
I m getting the error on the debug like :
*soChat.connect('chat', conn, true) => (void 0) (must be a
function)*
Actually i want to do this : call the *connect* method on the
class when the netStatusHandler method of the *conn* object has
been completed. I m not sure that am i using the delegate
correctly (as i m getting the error, of course not :)).
I have attached the relevant files.
Can anyone help me what i m missing to do.
Kind regards.
