Re: [flexcoders] Re: filter arraycollection with checkbox acting wired
Can you click on the checkbox more than once (let's say 5 times) and resend the output?

Re: [flexcoders] Re: filter arraycollection with checkbox acting wired
It seems like your data is OK. So I did a test application and I figured out
that the filter function is wrong. It should only do the test if the
checkbox is selected, otherwise it should always return true because in this
case you want display all items. So here is my working test app, I hope you
can use it to make your code work:
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; layout=vertical
mx:Script
![CDATA[
private var pizzaSelected:Boolean = false;
private function pizzaFilter():void
{
pizzaSelected = pizza_ckb.selected;
pizzaAr.refresh();
}
private function myFilterFunction(item:Object):Boolean
{
if (pizzaSelected)
return (item.pizza == pizzaSelected);
else
return true;
}
]]
/mx:Script
mx:ArrayCollection id=pizzaAr filterFunction=myFilterFunction
mx:Object label='Pizza 1' pizza='true' /
mx:Object label='Not a pizza 1' pizza='false' /
mx:Object label='Pizza 2' pizza='true' /
mx:Object label='Pizza 3' pizza='true' /
mx:Object label='Not a pizza 2' pizza='false' /
/mx:ArrayCollection
mx:CheckBox id=pizza_ckb change=pizzaFilter() /
mx:List dataProvider={pizzaAr} labelField=label /
/mx:Application

I've quit this one. The original poster needs to develop his debugging techniques before going any further.

Re: [flexcoders] Re: filter arraycollection with checkbox acting wired
You have to review the logic of your filter function. As Tracy said, you should try to debug, this will save you a lot of time. Put a break point in the filter function and test your conditions.

Re: [flexcoders] Re: filter arraycollection with checkbox acting wired
Replace the following functions, run the app in debug mode and post the
output:
private function pizzaFilter():void {
trace(pizza_ckb.selected);
if ( == true)
pizzaSelected = pizza_ckb.data;
filterGrid();
pizzaAr.refresh();
}
private function myFilterFunction(item:Object): Boolean
{
trace(item.pizza);
return (item.pizza == pizzaSelected) ;
}

Hi, Tim i tried your code, but the result is not good too. when then
check box is checked, all the data in the array collection disappears
and when its unchecked all data shows up again. what i want to achieve
is when the pizza_ckb is checked only the entries in the data base
that have pizza show up and when i uncheck it all entries with or
without pizza show up. thanks
RE: [flexcoders] Re: filter arraycollection with checkbox acting wired
I think I suggested already that you just need to debug this. Find an item that does not filter as you expect, step through the code til you hit that item, then step through the code to see why the filter function is not returning the expected value. It will almost certainly be obvious. For us to help, we need to do that process a a thought experiment. It will be much easier for you do do it in the debugger.
