Trouble getting geometry of projected point...

[GISAdmin1]

I have a simple request to project a point:

var projectedPoint =  gsvc.project([hiddenFacilities], outSR, function(projectedPoints){ 
 pt = projectedPoints[0];
 return(pt);
});

var hiddenFacilitiesGraphic = new esri.Graphic(projectedPoint, markerSymbol, attr); 

How do I get the geometry of projected point.  I can see the coordinates after inspecting projectedPoint in Firebug.  I just can't seem to use the object to create a graphic.

Thanks in advance,

M

on callback or onProjectComplete or dojo.Deferred you get geometry projected

gsvc.project([ point ], outSR, function(projectedPoints) {  projectedPoint = projectedPoints[0]; var hiddenFacilitiesGraphic = new esri.Graphic(projectedPoint, markerSymbol, attr);});

I originally had my code structured like this>:

for (var i = 0; i < facilityMaster.length; i++) {

       gsvc.project([hiddenFacilities], outSR, function(projectedPoint){ 
               
       pt = projectedPoint[0];
       hiddenFacilitiesGraphic = new esri.Graphic();
       hiddenFacilitiesGraphic.setGeometry(pt);
       hiddenFacilitiesGraphic.setSymbol(markerSymbol);  
       hiddenFacilitiesGraphic.setAttributes(i);   
       parkNameLayer.add(hiddenFacilitiesGraphic);
       });

}

The problem is, the projected graphic is not getting the attribute "i" (setAttributes(i)).  The created graphics all have the same attribute.  I need the projected graphics to have a unique value.

Thanks!

The behaviour is right because the clousure provided by anonymous function passed to projected doesn't resolve the variable 'i' until it's resolved

Can you suggest another approach?  Can I create the graphic with the attributes and then project the graphic instead of just the point geometry?

Project has in input array of geometry. You can do your loop into function like:

       gsvc.project([hiddenFacilities], outSR, function(projectedPoint){ 
            for (var i = 0; i < facilityMaster.length; i++) {
    pt = projectedPoint;
                hiddenFacilitiesGraphic = new esri.Graphic();
                hiddenFacilitiesGraphic.setGeometry(pt);
                hiddenFacilitiesGraphic.setSymbol(markerSymbol);  
                hiddenFacilitiesGraphic.setAttributes(...);   
                parkNameLayer.add(hiddenFacilitiesGraphic);
          }
       });
