RE: [Junk E-Mail - MED] [flexcoders] Binding array to repeater

Thu, 03 Aug 2006 08:02:48 -0700

Hmm, nope. This is what I tried

 

import mx.collections.ArrayCollection;

[Bindable]

public var arrMdta:Array = new Array();

private function init():void

{

            for(var i:Number = 1; i < 100; i++)

            {

                        var filePath:String = "assets/image";

                        if(i.toString().length == 1) filePath += "00";

                        if(i.toString().length == 2) filePath += "0";

                        filePath += i.toString() + ".jpg";

                        arrMdta.push(new Mdta(filePath));

            }

}

 

And in mxml

 

<mx:ArrayCollection id="acGallery" source="{arrMdta}" />

 

Repeater:

 

<mx:Repeater id="rptGallery" dataProvider="{acGallery}">

<ui:thumb imagePath="{rptGallery.currentItem.fileName}" />                                                                                 

</mx:Repeater>

 

No luck, now I don’t have any items.

Close... that's the point of binding to an ArrayCollection... make arrMdta into an ArrayCollection instead, and it'll work great.

Subject: [Junk E-Mail - MED] [flexcoders] Binding array to repeater

Hi,

I have a repeater with a thumbnail in it.

Code:

<mx:Repeater id="rptGallery" dataProvider="{arrMdta}">

<ui:thumb imagePath="{Mdta(rptGallery.currentItem).fileName}" />                                                                        

</mx:Repeater>            

In my script I have

[Bindable]

public var arrMdta:Array = [new Mdta("assets/image001.jpg")];

So far so good, I see my image (inside my thumb component there’s an mx:image, nothing fancy

Now the harder part, I try to bind the repeater to the array (as I’m doing here, but when I change my array, it doesn’t get updated automatically.

In my applicationComplete, I call function init();

private function init():void

{

for(var i:Number = 1; i < 100; i++)

            {

var filePath:String = "assets/image";

                        if(i.toString().length == 1) filePath += "00"; // just because images have filenames image001.jpg, etc

                        if(i.toString().length == 2) filePath += "0";

                        filePath += i.toString() + ".jpg";

                        arrMdta.push(new Mdta(filePath));

}

}

This doesn’t work, only when I put the following line:

rptGallery.dataProvider = arrMdta;

Why is it only working if I re-force the dataProvider? I thought that was the point of binding my data?

Thanks for any help,

Jonas
