[flexcoders] What Am I doing Wrong, View will not update when bound data is changed.
Using Cairngorm, I am maintaining an ArrayCollection of a custom data
type. This data is bound to the view, however, when I update the data
in the ArrayCollection, the view is not updated until I redraw all of
the custom components. Is there a way for each component to respond
when I modify the data?
Here is the code
CUSTOM COMPONENT
?xml version=1.0 encoding=utf-8?
mx:Canvas xmlns:mx=http://www.adobe.com/2006/mxml; width=100%
height=100% borderStyle=outset cornerRadius=20
mx:Script
![CDATA[
import com.dynamicmedicalventures.or_metrics.RoomModel;
import mx.events.FlexEvent;
[Bindable]
private var _data:RoomModel;
override public function set data(value:Object):void{
if(value != null){
super.data = value;
this._data = value as RoomModel;
}
dispatchEvent(new
FlexEvent(FlexEvent.DATA_CHANGE));
super.invalidateProperties();
}
override protected function commitProperties():void {
super.commitProperties();
if(data != _data){
_data = data as RoomModel;
}
}
]]
/mx:Script
mx:Label x=10 y=10 fontSize=14 fontWeight=bold
id=roomTitle text={_data.roomData.roomName}/
mx:Image x=846 y=10 id=roomStatus/
mx:List x=10 y=86 width=580 height=312 id=caseList
dragEnabled=true dropEnabled=true dataProvider={_data.caseList} /
mx:Label x=10 y=60 text=Case List/
mx:Label x=618 y=60 text=Main Staff/
mx:Label x=618 y=204 text=Misc Staff/
mx:List x=618 y=86 width=163 id=mainList height=110
dataProvider={_data.mainStaff} /
mx:List x=619 y=230 id=miscList width=163 height=110
dataProvider={_data.miscStaff} /
mx:Label x=10 y=415 text=Equipment List/
mx:HorizontalList x=10 y=441 width=580
dataProvider={_data.equipmentList} /
mx:Label x=619 y=360 text=Messages amp; Alerts/
mx:TextArea x=619 y=389 width=259 height=112/
/mx:Canvas
In the main application I am adding many of these custom components to
a VBOX, here is that code snippit
for (var i:int = 0; imodelLocator.RoomModelCollection.length; i++){
var newRoom:RoomView = new RoomView()
newRoom.data =
modelLocator.RoomModelCollection.getItemAt(i);
if(allRoomsBox) {
allRoomsBox.addChild(newRoom);
}
}
Thanks for any help

Is the [Bindable] tag present at the top of the RoomModel declaration?

RE: [flexcoders] What Am I doing Wrong, View will not update when bound data is changed.
How are you updating the item? If you use the collection API, the UI should
update. If you are directly assigning a value to an item property, then you
should call itemUpdated(item).
