Hi all, I am using geometry service's union to dissolve polygons. It works great. However, I cannot figure out why on my first draw-end my featurelayer selection is done but not the union. If I draw a second extent then it works. not too sure what I am missing here. Thanks, Alex here is my code: script > var map ; require ( [ "esri/InfoTemplate" , "esri/map" , "esri/layers/FeatureLayer" , "esri/symbols/SimpleFillSymbol" , "esri/symbols/SimpleLineSymbol" , "esri/tasks/query" , "esri/toolbars/draw" , "esri/tasks/GeometryService" , "esri/dijit/editing/Union" , "esri/graphic" , "esri/graphicsUtils" , "dojo/dom" , "dojo/on" , "dojo/parser" , "dojo/_base/array" , "esri/Color" , "dojo/domReady!" ] , function ( InfoTemplate , Map , FeatureLayer , SimpleFillSymbol , SimpleLineSymbol , Query , Draw , GeometryService , Union , Graphic , graphicsUtils , dom , on , parser , arrayUtil , Color ) { parser . parse ( ) ; var selectionToolbar , featureLayer ; map = new Map ( "map" , { basemap : "streets" , center : [ - 97.395 , 37.537 ] , zoom : 11 } ) ; map . on ( "load" , initSelectToolbar ) ; var fieldsSelectionSymbol = new SimpleFillSymbol ( SimpleFillSymbol .

Alex, The FeatureLayer.selectFeatures method returns a promise and it apears that you are not waiting for it to return in your code: featureLayer . selectFeatures ( selectQuery , FeatureLayer . SELECTION_NEW ) ; it should be something like: featureLayer . selectFeatures ( selectQuery , FeatureLayer . SELECTION_NEW , lang . hitch ( this , function ( ) { //Now do something with the newly selected features. } ) ) ;

The FeatureLayer.selectFeatures method returns a promise and it apears that you are not waiting for it to return in your code:

featureLayer<SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">.</SPAN><SPAN class="" style="color: #d74444; border: 0px; font-weight: inherit;">selectFeatures</SPAN><SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">(</SPAN>selectQuery<SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">,</SPAN> FeatureLayer<SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">.</SPAN>SELECTION_NEW<SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">)</SPAN><SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">;</SPAN>

it should be something like:

featureLayer<SPAN class="punctuation token">.</SPAN><SPAN class="token function">selectFeatures</SPAN><SPAN class="punctuation token">(</SPAN>selectQuery<SPAN class="punctuation token">,</SPAN> FeatureLayer<SPAN class="punctuation token">.</SPAN>SELECTION_NEW<SPAN class="punctuation token">,</SPAN> lang<SPAN class="punctuation token">.</SPAN><SPAN class="token function">hitch</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="keyword token">this</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="keyword token">function</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">{</SPAN>

That was the issue. Proxy was.

Still No errors (except the XMLHTTPRequest, is that the problem maybe?)

Anonymous User

Yes. It returns the number of polygons selected that are in my "targetGeometry" array as expected.

Alex,

Does the console.log show more than one geometry the first time through?

Anonymous User

Just tried but the call back does not trigger my geometry service the first time around.

Alex,

The FeatureLayer.selectFeatures method returns a promise and it apears that you are not waiting for it to return in your code:

featureLayer<SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">.</SPAN><SPAN class="" style="color: #d74444; border: 0px; font-weight: inherit;">selectFeatures</SPAN><SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">(</SPAN>selectQuery<SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">,</SPAN> FeatureLayer<SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">.</SPAN>SELECTION_NEW<SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">)</SPAN><SPAN class="" style="color: #999999; border: 0px; font-weight: inherit;">;</SPAN>

it should be something like:

featureLayer<SPAN class="punctuation token">.</SPAN><SPAN class="token function">selectFeatures</SPAN><SPAN class="punctuation token">(</SPAN>selectQuery<SPAN class="punctuation token">,</SPAN> FeatureLayer<SPAN class="punctuation token">.</SPAN>SELECTION_NEW<SPAN class="punctuation token">,</SPAN> lang<SPAN class="punctuation token">.</SPAN><SPAN class="token function">hitch</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="keyword token">this</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="keyword token">function</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">{</SPAN>
&nbsp;&nbsp; <SPAN class="comment token">//Now do something with the newly selected features.</SPAN>
<SPAN class="punctuation token">}</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>
