esriRequest with multiple map layers

GregoryBologna — Thu, 07 Nov 2019 21:58:30 GMT

How do I return multiple layers including a map layer that is a definitionExpression when doing an esriRequest?

If I request a single map layer that is a definitionExpression, the map layer is returned.

      {
         "id": 1,
            "layerDefinition": {
               "drawingInfo": drawingInfo,
                  "source": {
                     "type": "mapLayer",
                       "mapLayerId": 1
                  },
                  "definitionExpression": "PARID='"+parid+"'"
         }
      }

If I request two map layers, one with a definitionExpression, no map layers are returned.

"layers": [ { "id": 256,

"layerDefinition": {

"source": {

                  "type": "mapLayer", "mapLayerId": 256 }
             }
      },

If I request a single map layer that is not a definitionExpression, the map layer is returned.

Can you post some code that shows what you are trying to accomplish? What version of the JS API are you using? I'm not sure how you're using esriRequest or what you mean by mapLayer.

I am constructing a json esriRequest and posting it to Printing Tools Task. The "layers" are in the request.

Ok, sorry, I don't know how to help. What version of the JS API are you using? Are the layers MapImageLayers or FeatureLayers?
