Custom FCS Component Binding Issues
|
|
| Harper, Chris 2005-04-07, 5:57 pm |
| Hi all,
I've built a V2 component that connects to FCS and creates a shared
object inside of itself to store a users list. It extends the MovieClip
class (not UIObject or UIComponent). I've also built a component that
extends MovieClip that displays the users connected. How do I bind
these two so when the connection gets an update to the Shared Object it
updates all the other components that need that users list? I've tried
everything in the code for the components and in the component inspector
but there just isn't enough documentation on this.
=20
Here are links to the classes for both components if somebody would like
to take a look:

Perfect case for using the EventDispatcher API.
Mix in the EventDispatcher API into FCS_Connection (an easy way to do
this is to simply extend UIComponent rather than MovieClip). Now, in
your onSync handler for the shared object, dispatch a custom event via
the dispatchEvent method, say "userListChange".
In all other interested components, have them add listeners to the
FCS_Connection component for this event and act accordingly when its
fired.

that multiple components can respond to onSync messages. This is similar
to MVC and having multiple views respond to changes in a single model.
If you have programming Flash Communication Server have a look at the
"Listenable Shared Objects" section on page 485. You'll also find the
source for the SharedObjectFactory in either the PeopleList.zip or
PeopleGrid.zip files here:

| Thanks you guys. Brain, I still need to buy the book 
So is there a way to use the [Bindable] meta tag in the FCS_Connection
and the UserList components instead of using listeners? =20
I'm trying to let the people in creative just drop the FCS_Connection
component into their flash pieces and then use the binding tab in the
Component Inspector to sync it to whatever other component they want.
Thanks!
Chris

| Hi Chris,
I don't bother with the component inspector but I think you can. If you
look in the PeopleGrid.zip file's fla you'll see something like this in
the Room frame of the timeline:
peopleGrid.nc = application.nc;
status.nc = application.nc;
videoConference.people_so = peopleGrid.people_so;
In other words the peopleGrid has a getter named people_so that returns
a reference to the shared object it manages. The videoConference
component has a setter named people_so that it uses to set itself up as
a listener on the peopleGrid's shared object. Since the shared object
was created using the SharedObject factory it is already an event
broadcaster.
To simplify things a bit, the videoConference component does this:
__people_so = people_so;
__people_so.addEventListener("onSync", this);
if (__people_so.isConnected){
var list = [];
for (var p in __people_so.data){
list.push({code:"change", name: p});
}
onSync({target:__people_so, list:list});
The videoConference has its own onSync method that will be called
whenever the people_so shared object is synchronized. The
videoConference component never updates the people_so. That is the job
of the PeopleGrid.
Does that help?
Yours truly,
-B

| Thanks brian, I'll try to wrap my head around that
Mostly though, I was wanting to use the [Bindable] meta tag like I would
if I where building any other component. So it would look like this:
//------------------------------------------//
//Code in the FCS_Connection component class//
//------------------------------------------//
/////This is outside of the class (not sure if its needed//
[Event("change")]
/////Getter setter for BindData//
=09
[ChangeEvent("change")]
[Bindable ("readonly")]
public function set BindData (argValue : Object) : Void {
=09
__BindData =3D argValue;
=09
}
=09
public function get BindData() : Object {
=09
return __BindData;
=09
}
////The shared object code//
function initLobbyResources(nc){=09
=09
var tempOwner : FCS_Connection =3D this;
globalUserList_so =3D
SharedObject.getRemote("globalUserList_so", nc.uri, false);=09
globalUserList_so.ready =3D false; =20
globalUserList_so.onSync =3D function(list){
for (var p in this.data){
tempOwner.BindData =3D this.data[p];
}
=09
}
=09
globalUserList_so.connect(nc);
=09
}
//------------------------------------//
//Code in the UserList component class//
//------------------------------------//
////Getter setter in the UserList//
[Bindable("writeonly")]
public function set users(argValue:Object) { =09
__users =3D argValue;
trace ("SET users called");
draw(); =09
}
public function get users():Object{ =09
trace ("GET users called");
return __users; =09
}
//-----------//
//End of Code//
//-----------//
Granted, I'm new to building v2 components :D

I "think" you should be able to do a bindable setter like
public function set people_so (people_so:SharedObject){
__people_so = people_so;
__people_so.addEventListener("onSync", this);
if (__people_so.isConnected){
var list = [];
for (var p in __people_so.data){
list.push({code:"change", name: p});
}
onSync({target:__people_so, list:list});
}
Otherwise you could have the owner of the shared object do exacty what
Jim was suggesting.

| Huh, so is there no way to do a regular data binding like you would do
with the XMLConnector data component?

Perfect case for using the EventDispatcher API.
Mix in the EventDispatcher API into FCS_Connection (an easy way to do=20
this is to simply extend UIComponent rather than MovieClip). Now, in=20
your onSync handler for the shared object, dispatch a custom event via=20
the dispatchEvent method, say "userListChange".
In all other interested components, have them add listeners to the
FCS_Connection component for this event and act accordingly when its
fired.

Sure. I'm not sure whether it'll compile (haven't tried it and I don't
have the rest of your source code anyhow), but here's how I'd do it
using your classes. Look for the comments prefixed with JMC for my
changes to add in event dispatching of the user list change:
http://dev.psalterego.com/FCS_Connection.as
http://dev.psalterego.com/UserList.as
For cases like this, the EventDispatcher API really rocks. It basically
provides a means for class instances to register to be notified of an
interesting event in another class instance (they don't have to even be
related). Unlike the old-school callbacks, the EventDispatcher API
supports essentially an unlimited number of registered listeners.
You can read more about it in the Components documentation included with
Flash MX 2004.

| Hi Chris,
I meant the opposite. I think you can - its just that I have never
bothered. What I was thinking was:
1. Inside one component use SharedObjectFactory.getRemote() to get an SO
that is already an event broadcaster.
2. create a getter to get the shared object from that component and a
setter within another component
3. declare the getters/setters bindable (or whatever you have to do to
make the component inspector see the getter and setter).
4. bind the components in the inspector on the shared object property.
For example on people_so
Now both components will have a reference to the shared object and both
will receive onSync events. I don't know if that's really what you're
looking for but if it sounds right I'll try to find a few minutes to
check that it all works that way. If Jim's suggestion looks like an
easier path that's cool too.
Yours truly,
-Brian

| I'm about to check out Jim's method. Simpler questions would be:
1. How do you make a v2 component that extends the MovieClip class (not
UIComponent or UIObject) that can send bindable data with the [Bindable]
tag from its own SO?
2. How do you make a component that can receive this bindable data

| Hi Chris,
I'm still struggling with why you would want to propagate shared object
updates via a bindable property but you can make a movie clip into an
event broadcaster by doing this in it's constructor or onLoad method:
<>mx.events.EventDispatcher.initialize(this);
I don't know if that is all you need to answer question 1 though.

Hmm, I can't really help you there.
As nice as they are for non-developers, I know virtually nothing about
data binding, having taken the oath against data binding the day I
started to learn Actionscript from the alien overlords (just kidding!).
From a development perspective, the Event Dispatcher API is much more
flexible, as well as simpler, than the rarely-used Data Binding API.
While data binding is typically taught to allow designers and other
non-developers to quickly have access to XML and RDBMS content from
Flash, I personally know very little about the API and aside from the
connectors that shipped with Flash MX 2004, haven't seen data binding
used very much at all by the Flash development community as a whole.
Looking through the MM documentation, there is some discussion of the
API in the Components Dictionary under "Data binding classes," though
I'm not sure where to send you for more information aside from that.

| Hi Chris,
I don't know if I'll have time to play with shared objects but I have a
bindable netconnection now. I could not get it to work when subclassing
a movie clip. I had to subclass a UIComponent. The magic seems to happen
in super.init().

| Hi Chris,
Here is a demo that does something like what you want:
http://www.flash-communications.net...le/bindable.zip
It binds a NetConnection that is updated when the connection is
established and broken and binds a shared object info object containing
a reference to the shared object and the last infoList passed into
onSync whenever there is an onSync call.
I don't think I like this approach but I have it working and so it may
be of some use to you. I think a better approach would be to bind the so
itself and make it an onSync broadcaster. But maybe I'll try that some
other day...
Cheers,
-Brian

| Thanks you guys for all your help. I'm taking a look at your stuff now

Stefan, I just don't want to include anything I don't need. Also, by
not extending the UIObject or UIComponent just makes me build everything
from scratch and understand how components work a little better I
guess it's more for my education than anything else.
