Thank you for your help! Finaly, the
http://www.cflex.net/showFileDetails.cfm?ObjectID=415&Object=File&ChannelID=1
option.
The logic of this thing is to copy the collection in a array and push
the reset value in. If the collection change, we need to repopulate de
fake array.
//////////////MAIN ACTIONSCRIPT//////////////
[Bindable]
public var categoryFilter : Array = new
ArrayFilter(myModel.categoryData,"Show All");
private function checkIfShowAll(item:Object):Boolean{
return item.hasOwnProperty("resetFilter")&& item.resetFilter
}
private function initApp():void{
myCustomEntry.filterFunction = globalFilter
myCustomEntry.refresh()
}
private function globalFilter(o:Object):Boolean {
var show:Boolean=true
if(!checkIfShowAll(cboLayer.selectedItem) &&
cboLayer.selectedItem!=null && o.layer!=cboLayer.selectedItem ){
show = false
}
return show
}
...
//////////////MAIN MXML//////////////
<mx:ComboBox id="cboLayer" width="169" x="61" y="2"
change="myCustomEntry.refresh()"
dataProvider="{layerFilter}" labelField="name" />
...
/////////////ArrayFilter CLASS//////////////
dynamic public class ArrayFilter extends Array{
import mx.collections.ArrayCollection
import mx.events.CollectionEvent;
private var resetString:String;
private var sourceFilterCollection:ArrayCollection;
public function
ArrayFilter(sourceFilterCollection:ArrayCollection,resetString:String="All"):void{
super()
this.sourceFilterCollection=sourceFilterCollection;
this.sourceFilterCollection.addEventListener(CollectionEvent.COLLECTION_CHANGE,refreshMyArray)
this.resetString=resetString;
refreshMyArray(new
CollectionEvent(CollectionEvent.COLLECTION_CHANGE))
}
public function refreshMyArray(event:CollectionEvent):void
{
//remove all and insert after (will be better to check
CollectionEvent...)
this.splice(0,this.length)
var n:int = sourceFilterCollection.source.length;
for (var i:int = 0; i < n; i++){
this.push(sourceFilterCollection.source[i]);
}
this.sort();
var o:Object = new Object();
o.resetFilter=true;
o.toString=function():String{
return resetString;
}
this.unshift(o);
}
}
