So I'm trying to be as explicit as I can.
The reason for which I choose to go with a module is because there will
be a lot of users which won't be interesetd in acessing this
functionality. It is a window which displays a chart and a datagrid.
Now the the application is a simulation of a horse race and you can
place bets on each of the horses you consider will win. (go to
games.betfair.com and start the - card derby racing game). What you
cannot see now is that when user wil click on either Spades, Hearts,
Clubs, Diamonds in there a pop-up window will show up and will display
information about the betting volume over time. That is the window I am
talking about. So I have a title window in the main application and I
load a module via module loader in that window. (if you look at any
other games at games.betfair.com you's lee when you click on a market
name in there a javascript pop-up showing up with a chart and a grid in
there). I am building something like that in flex...
The main app is based on cairngorm, and I also have cairngorm in my
module a separate controller, and using a simple httpService with the
urls got from the mai app. The module listens for some variables in the
main app and when that change, the bindings tiggers and updates the
chart and datagrid via httpService calls.
I'll paste some code snippets in here so you can get a better
understanding:
The module:
//======================================================================\
=================================================
// Private fields
//======================================================================\
=================================================
private var _currencyFormater : CurrencyFormatter = new
CurrencyFormatter();
[Bindable]
private var _model : MarketInfoModel =
MarketInfoModel.getInstance();
//i use these for unwatching the bindings when the module unloads
private var _gameMarketIdChangeWatcher : ChangeWatcher;
private var _gameSelectionClickedChangeWatcher : ChangeWatcher;
private var _updateTradeActivityInfoChangeWatcher :
ChangeWatcher;
private var _gameMarketSelctionInfoChangeWatcher :
ChangeWatcher;
//the init event handler
private function initModuleVars() : void
{
//get the appmodel
this._model.gameModel = GamexModel.getInstance();
this._model.url =
((this._model.gameModel.urls.tradeActivityInfo == null) ||
(this._model.gameModel.urls.tradeActivityInfo == '')) ?
this._model.gameModel.altURLS.tradeActivityInfo :
this._model.gameModel.urls.tradeActivityInfo;
this._model.currentMarketId =
this._model.gameModel.channel.game.market.marketInfoChangeTrigger.trigge\
ringMarketId;
this._model.currentSelectionId =
this._model.gameModel.channel.game.market.marketInfoChangeTrigger.trigge\
ringSelectionId;
//init the model Httpservice with this HTTPService
this._model.httpService = this.marketInfoHTTPService;
//set the currency formatter
this._currencyFormater.precision = 2;
this._currencyFormater.rounding =
NumberBaseRoundType.NEAREST;
this._currencyFormater.currencySymbol =
this._model.gameModel.user.currency.symbol;
trace("init");
}
creationComplete eventHandler
/**
* creationComplete eventHandler
* @return void
*/
private function onCreationComplete() : void
{
trace("1");
this._gameMarketIdChangeWatcher =
BindingUtils.bindSetter(this.onGameMarketIdChanged,
this._model.gameModel.channel.game.market, "id");
trace("2");
this._gameSelectionClickedChangeWatcher =
BindingUtils.bindSetter(this.onGameSelectionClicked,
this._model.gameModel.channel.game.market.marketInfoChangeTrigger,
"triggerMarkeInfoChange");
trace("3");
this._updateTradeActivityInfoChangeWatcher =
BindingUtils.bindSetter(this.updateTradeActivityInfo,
this._model,"trigger");
trace("4");
this._gameMarketSelctionInfoChangeWatcher =
BindingUtils.bindSetter(this.onGameMarketSelctionInfoChanged,
this._model.gameModel.channel.game.market, "triggerModuleGridUpdate");
trace("creation complete");
}
Basically the "init" handler fires for all children and then for the
whole module, it is the creation complete that doesn't get called
sometimes untile very late or the end of the game. Bu it you give time
until then it will show up evetually. The polling for data only happend
when the above bindings are set. I poll for data only inside those
setters...
This morning I have set creation policy to quequed for the module and I
wasn't able to reproduce it until now. However this is not something I
can be sure of that it is indeed the fix... And the fact that this
happend very randomly doesn't help that much either....
TIA,
Claudiu

like the bindings are not init, the event doesn't get dispatched. The
setters are the one who dispatch cairngorm events and in the command
(actually delegate) I make a request to the server.
