Bug? bboxSR=null&imageSR=null

FlorianLeman

Hello,
I encounter a problem with my application. At startup, I make a query to retrieve a point and I zoom on it.
The first image loads correctly (unzoomed), but just after the zoom, the api try to load a new image and I have the following error:

Error: Chargement de l'image impossible: http://10.1.0.100/ArcGIS/rest/services/Map_dynamic/MapServer/export?dpi=96&amp;transparent=true&amp;format=png8&amp;bbox=382398.38085919805,150171.12439732553,382872.5151407999,150407.13320267646&amp;bboxSR=null&amp;imageSR=null&amp;size=896,446&amp;f=image

If I unzoom and zoom on the same point (immediatly), I have the same request, bug bboxSR and imageSR are well-filed :

http://10.1.0.100/ArcGIS/rest/services/Map_dynamic/MapServer/export?dpi=96&amp;transparent=true&amp;format=png8&amp;bbox=382398.38085919805,150171.12439732553,382872.5151407999,150407.13320267646&amp;bboxSR={"wkt":"PROJCS[\"NTF_Lambert_Zone_II\",GEOGCS[\"GCS_NTF\",DATUM[\"D_NTF\",SPHEROID[\"Clarke_1880_IGN\",6378249.2,293.46602]],PRIMEM[\"Greenwich\",0.0],UNIT[\"Degree\",0.0174532925199433]],PROJECTION[\"Lambert_Conformal_Conic\"],PARAMETER[\"False_Easting\",600000.0],PARAMETER[\"False_Northing\",200000.0],PARAMETER[\"Central_Meridian\",2.3372291667],PARAMETER[\"Standard_Parallel_1\",45.8989188889],PARAMETER[\"Standard_Parallel_2\",47.6960144444],PARAMETER[\"Scale_Factor\",1.0],PARAMETER[\"Latitude_Of_Origin\",46.8],UNIT[\"Meter\",1.0]]"}&amp;imageSR={"wkt":"PROJCS[\"NTF_Lambert_Zone_II\",GEOGCS[\"GCS_NTF\",DATUM[\"D_NTF\",SPHEROID[\"Clarke_1880_IGN\",6378249.2,293.46602]],PRIMEM[\"Greenwich\",0.0],UNIT[\"Degree\",0.0174532925199433]],PROJECTION[\"Lambert_Conformal_Conic\"],PARAMETER[\"False_Easting\",600000.0],PARAMETER[\"False_Northing\",200000.0],PARAMETER[\"Central_Meridian\",2.3372291667],PARAMETER[\"Standard_Parallel_1\",45.8989188889],PARAMETER[\"Standard_Parallel_2\",47.6960144444],PARAMETER[\"Scale_Factor\",1.0],PARAMETER[\"Latitude_Of_Origin\",46.8],UNIT[\"Meter\",1.0]]"}&amp;size=896,446&amp;f=image

I don't if it is because I use a spatial reference which doesn't have a wkid or anything else...

Any ideas?

Greetings,
FL

Do you have a public map service I can use to test? If so, please post some code to repro the issue.

FlorianLeman

Memoris is a silver member, so yes, I can. Its justs generally a little longer (french support)
The strange thing is that, if I remove bboxSR=null&imageSR=null, the exported image loads well...

This should be working as we do support well-known text for custom spatial references. Are you able to open a call with support?

FlorianLeman

What do you you see if you do this:
console.log(r.geometry.spatialReference);
Does that spatial ref match your map's?

Yes, it does perfectly.

I should have said :
"I don't if it is because I use a spatial reference which doesn't have a wkid or if it is anything else..."

Of course, I have a spatial reference, but a custom one :

this.sr = new esri.SpatialReference({  "wkt":'PROJCS["NTF_Lambert_Zone_II",GEOGCS["GCS_NTF",DATUM["D_NTF",SPHEROID["Clarke_1880_IGN",6378249.2,293.46602]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Lambert_Conformal_Conic"],PARAMETER["False_Easting",600000.0],PARAMETER["False_Northing",200000.0],PARAMETER["Central_Meridian",2.3372291667],PARAMETER["Standard_Parallel_1",45.8989188889],PARAMETER["Standard_Parallel_2",47.6960144444],PARAMETER["Scale_Factor",1.0],PARAMETER["Latitude_Of_Origin",46.8],UNIT["Meter",1.0]]'
});

The spatial reference is a copy/paste of the map service definition.

My code :
Please note that mm is a reference to a MapManager (custom), the member map an esri.Map object. I can't post the whole application (too big!).

zoom_query: function(layerName, fieldName, id, scale, outFields){
 var query = new esri.tasks.Query();
 if (typeof(id) == 'string') id = "'"+id+"'";
 query.where = fieldName+" = "+id;
 query.returnGeometry = true;
 if (outFields !== undefined){
  query.outFields = outFields;
 }
 var thisref = this;
 var l = this.mm.getLayerByName(layerName);
 if (l == null){
  alert("zoom_query->Layer "+layerName+" don't exist");
   return;
  }
  l.queryFeatures(
   query,
   function(featureSet){
    var r = featureSet.features[0];
    if (thisref.apv.type == 'Point'){
     var zoomLevel = thisref.mm.map.setLevel(thisref.mm.getScaleLevel(thisref.apv.scale));
     thisref.mm.map.centerAndZoom(r.geometry, zoomLevel);
    }
    thisref.mm.showInfoWindow(r);
   },
   onError
  );
 }
}

So, I just retrieve a point and zoom on it. The scale level is defined in the basemap, which is not displayed at this time. The failure comes from a dynamic map service.

Kind regards,
FL

Can you elaborate on this? What is your spatial reference if it "doesn't have a wkid or anything else"? Also, please post your code you're using to define your point and zoom the map.
