[flexcoders] HTTPService retrieves no data within itemrenderere

[kaushal.shah123]

I have an Horizontal list that is connected to "patients"
arraycollection.

I've created an Canvas Itemrenderer for the horizontal list that lists
the patient's medical information.

Within the itemrenderer, I am calling out to a PHP HTTPService call to
retrieve the visits for each patient.   However I am not getting any
data returned.

If I run the HTTPService in the main application, it works.







My main app code below:

<mx:HorizontalList id="h_compare" width="100%" height="100%"
dataProvider="{myCompare}" labelField="name"
itemRenderer="comparerenderer" columnWidth="500"

rowHeight="{hbox_compare.height}" borderColor="haloBlue"
scrollTipFunction="horizontalList_scrollTipFunc" showScrollTips="true" 
alternatingItemColors="[#FFFFFF, #EEEEEE]" backgroundAlpha=".5"
removedEffect="{fadeOut}"/>







Itemrenderer code below  (Screenshot also attached).
