Conditionally hide an image in grid renderer if data is empty?

Question

I have a project that mostly uses Spark Lists.  For some of the items in my collection, a particular image might not exist or be required; I leave that XML node empty.  This is working fine in the spark renderer for the List, like this:
<mx:Image width="120" source="images/logos/{XML(data).logo}" visible="{XML(data).logo.length>0}" />
However, in this project I also need to use a PrintDataGrid of the same data for printing.
But for some reason, a similar approach just leads to the images printing anyway, which of course print as "broken" images.
<mx:DataGridColumn width="120">
     <mx:itemRenderer>
          <fx:Component>
               <mx:Image width="120" height="75"  source="images/logos/{XML(data).logo}" visible="{XML(data).logo.length>0}"   />
          </fx:Component>
     </mx:itemRenderer>
</mx:DataGridColumn>
How can I not show the image in the PrintDataGrid when appropriate, as I can with the List?

Hi,
use isempty function of PHP while checking using the filed
name, as even if the filed has or not any value it will always be
greater than 0 and can be tracked if using isempty function of PHP.
Hope this helps,
