//Allways set to null first!!!! else you get filter inside
the filter!
myArrayCollection.filterFunction=null;
Cato,
Can you give an example of this? I tried the following and
var foo:ArrayCollection = new ArrayCollection([1,2,3,4]);
trace(foo);
foo.filterFunction = function(num:int):Boolean {
return num % 2 == 1;
};
foo.refresh();
trace(foo);
foo.filterFunction = function(num:int):Boolean {
return num % 2 == 0;
};
foo.refresh();
trace(foo);
foo.filterFunction = null;
foo.refresh();
trace(foo);
--- produces ---
1,2,3,4
(Array)#0
[0] 1
[1] 3
(Array)#0
[0] 2
[1] 4
1,2,3,4
I don't think ListCollectionView composes filterFunctions.

Hi if you use java as backend do you serilaze the object ?
if so you can map the date objec to the date object in actionscript and
back..
here is a datefilter connetced to a arraycollection.
public function chkToDay():void
{
//Allways set to null first!!!! else you get filter inside
the filter!
myArrayCollection.filterFunction=null;
myArrayCollection.refresh();
myArrayCollection.filterFunction=toDayDateFilterFunc;
/* Refresh the collection view to apply the filter. */
myArrayCollection.refresh();
}
and the filter function
private function toDayDateFilterFunc(item:Object):Boolean
{
var toDay:Date = new Date();
//item.date is if you have a public var named date in your
DTO(Data Transfer Object)
return item.date== toDay;
}
