Dear all developers, its been a week I have been trying to solve this minor issue, so any help is highly appreciated. I have a point layer that loads into a graphics layer in the app representing commercial advertisers. Initially I embedded the symbol with a code that worked fine (pasted below), as I only had three entries, the embedding was fine, and I was checking the query result for name, and with If statements, I was assigning the graphics symbol. Here is the relevant parts of the code that worked. Am using the 2.3 flex API with Flex Builder 4The Embed code that worked fine:
[Embed(source='images/Commercial_Logos/ZAS.png')]
private var picEmbeddedZAS:Class;
private var zasMarkerPicture:PictureMarkerSymbol = new PictureMarkerSymbol(picEmbeddedZAS);
private function doQueryComm() : void
{
queryCommercial.geometry = myMap.extent;
queryTaskCommercial.execute( queryCommercial, new AsyncResponder( onCommResult, onCommFault ));
}
private var commData:Object;
private function commercialClickHandler (event:MouseEvent):void
{
commData = event.target.parent.attributes;
commIdentVariable = new commercialDetailsWindow();
PopUpManager.addPopUp(commIdentVariable, this, false);
}
private function onCommResult( featureSet : FeatureSet, token : Object = null ) : void
{
for each ( var myCommGraphic : Graphic in featureSet.features )
{
//here is where I check for the name, and assign the symbol
if (myCommGraphic.attributes.Name == 'ZAS - Z Aviation Services')
{
myCommGraphic.toolTip = 'ZAS - Z Aviation Services';
myCommGraphic.symbol = zasMarkerPicture;
commGraphicsLayer.add(myCommGraphic);
}
}
}
<esri:QueryTask id="queryTaskCommercial" url="http://arcgis2.roktech.net/ArcGIS/rest/services/DigitalEg/English/MapServer/3"/>
<esri:Query id="queryCommercial" outFields='["Name" , "Type" , "LargeLogo" , "SmallLogo"]'
returnGeometry="true" />
<esri:Map id="myMap" extentChange="doQueryComm();">
<esri:GraphicsLayer id="myCommGraphicsLayer" symbol="{mySFS}"/>
<esri:GraphicsLayer id="commGraphicsLayer" click="commercialClickHandler(event);" >
</esri:GraphicsLayer>
</esri:Map>
I am attempting to load the path to the symbol source from a field called SmallLogo, I tried assigning the source using a variety of methods, and it failed in all. I tried to assign the source to myCommGraphic.attributes.SmallLogo and then to commData.SmallLogoLogo, both didn't work. Below is my last attempt to do so.
private var commData:Object;
private var commercialMarkerPicture:PictureMarkerSymbol ;
private function doQueryComm() : void
{
queryCommercial.geometry = myMap.extent;
queryTaskCommercial.execute( queryCommercial, new AsyncResponder( onCommResult, onCommFault ));
}
private var commData:Object;
private var commercialMarkerPicture:PictureMarkerSymbol
private function onCommResult( featureSet : FeatureSet, token : Object = null ) : void
{
for each ( var myCommGraphic : Graphic in featureSet.features )
{
myCommGraphic.toolTip = commData.Name;
commercialMarkerPicture = new PictureMarkerSymbol( myCommGraphic.attributes.SmallLogo) ;
myCommGraphic.symbol = commercialMarkerPicture;
commGraphicsLayer.add(myCommGraphic);
}
}
private function commercialClickHandler (event:MouseEvent):void
{
commData = event.target.parent.attributes;
commIdentVariable = new commercialDetailsWindow();
PopUpManager.addPopUp(commIdentVariable, this, false);
commIdentVariable.addEventListener("OK",commercialCloseHandler)
commIdentVariable.commercialNameTextID.text = commData.Name;
//bla bla bla
}
//Code for Query task and Map are identical to above
I also tried this -- myCommGraphic.symbol = myCommGraphic.attributes.SmallLogo;That didn't work to.
