Re: [swiz-framework] Issue with loss of data when navigator.pushView(someView) is used

[Brian Kotek]

Not sure I follow. Are you saying that you set up the variable as a new ArrayCollection, and then at some later time something is setting it to null? If so, you could add a get/set pair for the property and use log messages or the debugger to see what is setting it to null.

I have set up a Swiz project and all seems well.  Im building an app using TabbedViewNavigatorApplication.

I have declared my beans in the configuration file and have 2 views and an xml service which I have set up using the connect to data Flex tool.

In the controller, I have a bindable ArrayCollection which is populated after a call to the method on the cfc on the server. It populates and is bound to the spark List component as its data provider.

When navigator.pushView(someView) is called - the ArrayCollection is set to null.

Any clues as to why this is happening?

yes that is what seems to be happening and it seems to be when I move away from the first view. 

Ive set up the ArrayCollection with getter/setter functions and have put a break point in the setter but nothing happens. If something is setting it to null then it should fire right? When I navigate away then I get an error when the ArrayCollection is trying to be accessed.

Code:

                private var _ips:ArrayCollection = new ArrayCollection;

[Bindable(event="ipsChanged")] 

// Define public getter method. 

public function get ips():ArrayCollection 

{ 

return _ips; 

} 

// Define public setter method. 

public function set ips(value:ArrayCollection):void 

{ 

_ips = value;

// Create event object.  

var eventObj:Event = new Event("ipsChanged"); 

dispatchEvent(eventObj); 

}

As it stands the ArrayCollection is declared in the controller and I inject it into the view I need. It seems that it needs to be sitting in a model so that I can keep all my data together. Im new to Swiz so what Im thinking of doing is to declare a model bean in the config say: <ipmodel:IpModel id="ipModel"/> then inject the model into the controller which will set the data to the ArrayCollection after its retrieved it. 

Would I then inject the model or the controller into the view needing the ArrayCollection?
