I have a procedure in a Flex project using the ArcGIS API for Flex 1.3. I am applying Graphics to a GraphicLayer based on Zip Codes. Some Zipcodes I use the backward symbol, some others I use the forward symbol. Below is how I declared them. My problem is the zip codes are being applied to the correct graphic symbol but when my map comes up, the zip codes have the same (forward) diagonal line graphic. It doesn't seem to put a backward symbol on it even though I set the symbol correctly. Is there an actual backward line or am I doing something wrong?
 <esri:SimpleFillSymbol id="defaultFillSymbolForwardDiagonal" color="0x000000" alpha="1" style="forwarddiagonal">
     <esri:SimpleLineSymbol color="0x000000" width="2" alpha="1" style="solid" />
 </esri:SimpleFillSymbol>
 <esri:SimpleFillSymbol id="defaultFillSymbolBackwardDiagonal" color="0x000000" alpha="1" style="backwarddiagonal">
     <esri:SimpleLineSymbol color="0x000000" width="2" alpha="1" style="solid" />
 </esri:SimpleFillSymbol>
