[flexcoders] Binding Request result to ComboBox

[pdflibpilot]

I am having trouble populating a ComboBox with items returned from a
HTTPservice request.

My results are returned in the following format

<records><record><label>2 Text</label><data>2</data></record><records>

I am using an ArrayCollection like this

<mx:ArrayCollection id="toc" source=
"{ArrayUtil.toArray(mzRequest.lastResult.records.record)}" />


<mx:ComboBox dataProvider="{toc}" >

The result is my comboBox displays [object Object],[object Object]

What am I missing here ??
