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

[Clint Tredway]

set this, arrMdta, to a type of ArrayCollection not just an array..

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.

[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
