Reprojecting results from find task

JimWharton

I'm returning a bunch of objects from a find task that I'm performing, and my results are ending up in South Africa, not Florida where they should be.

My map is using a spatial reference of 102100. My results are coming back with a WKID of 2236.

I have tried specifying

findParams = new esri.tasks.FindParameters(); findParams.outSR = '102100';

I've also tried specifying that WKID as an integer (no quotes). I've tried specifying a new spatial reference like this:

var sr = new esri.SpatialReference(102100); findParams = new esri.tasks.FindParameters(); findParams.outSR = sr;

No matter what, my results come back with a WKID of 2236... and naturally, those plot quite far away from where they should.

How do I get these points back where they belong?

Heres a fiddle which shows how to reproject returned geometries successfully.

I double checked my previous post and noticed that i had accidently copied the incorrect property name "outSR" in my code rather than "outSpatialReference". I corrected the previous post to avoid further confusion.

I'm going to need to go back and try that! Thanks.

I rewrote the whole app based on WKID 2236 and used dynamic layers on top of that. That got me the result I needed, but I still have the old code in GIT so I can't wait to try your soluction.

Thanks for getting back to me on this!

Thanks. Unfortunately, the objects are still coming back with a spatialReference of 2236.

I loop through the results like this:

dojo.forEach(results, function(result) {
      var graphic = result.feature;
      // x = graphic;
      // dataForGrid.push([result.layerName, result.foundFieldName, result.value]);
      switch (graphic.geometry.type) {
      case "point":
        graphic.setSymbol(markerSymbol);
        break;
      case "polyline":
        graphic.setSymbol(lineSymbol);
        break;
      case "polygon":
        graphic.setSymbol(polygonSymbol);
        break;
      }
      console.log(graphic);
      map.graphics.add(graphic);

    });

When I log out the graphic object (that I set to the feature attribute of the result) the spatial reference doesn't change.

The outSpatialReference property of findParameters is expecting a spatial reference object. The code below demonstrates the proper syntax.

ie:

var sr = new esri.SpatialReference({wkid:102100});
//findParams.outSR = sr (incorrect)
findParams.outSpatialReference = sr
