model to model communication

Hi!
Does pixlib have some solution for the case when I need to actually make a
modelA listen to modelB because the change in modelB is not from a command
but from the server?
Maybe this is more a general question but any hint from the masters would
be great

A quick answer...
What you could do is firing a command when you are receiving result in your proxy class. ( modelB )
or you can make  modelA implementing your ProxyListener ( if you need custom event, as I'm sure you will ) and add it to the listener collection of your modelB. modelB.addListener ( modelA )
or when you are calling a command that fire ( by any way ) a method call on the server you could put a callback that would update modelB and modelA like eg ( here it's AS3, adapt the Delegate for AS2 )

 ; &nbsp;  &nbsp;  override public function execute( e : Event = null ) : void
 ; &nbsp;  &nbsp;  {
 &nbsp;   &nbsp;   &nbsp;  ProxyServices.getInstance().getPoll( Delegate.create( _onResult ), Delegate.create( _onFault ) );
 &nbsp;   &nbsp;  }
 &nbsp;   &nbsp; 
 &nbsp;   &nbsp;  private function _onResult( result : * ) : void
 ; &nbsp;  &nbsp;  {
// update here
 ; &nbsp;  &nbsp;  }

 &nbsp;   &nbsp;  private function _onFault( fault : * ) : void
 ; &nbsp;  &nbsp;  {
 &nbsp;   &nbsp;  }

is calling the getPoll on my proxy class
In this function I have

public function getPoll( onResult : Function, onFault : Function ) : void
 ; &nbsp;  &nbsp;   &nbsp;  var responder : Responder = new Responder( onResult, onFault);
  ;   &nbsp;   &nbsp;  _ncService.call(";url", responder );
}

Hope that could help

Hi,

May be that server interaction shouldn9;t be the responsibility of the
model but rather handled by a command. This server response results from
a server requests that results from a user interaction (in some sort of
way), which is the job of control logic, ie commands. That's why I have
the commands handle the server requests and responses and update the
required models accordingly.

This helps keeping the model focused on its work, otherwise it can grow
rapipdly with all this server interaction logic. Plus it keeps the
server interaction modular since you can have one command per server
request.

Hope this helps,
fluxs
