Subject	creating a geometry object from json response
Author	p. thibault
Date	Oct 09, 2009
Message	I have a json response created by a REST service (as seen in code sample). How do I take the RING and build a geometry object in javascript? Does anyone have a sample? I have tried a number of interations of the following: geometry = new esri.geometry.fromJson(curFeature.geometry.rings[0]); Thanks
	REST service reponse: showResults({ "results" : [ { "layerId" : 1, "layerName" : "Parcels *", "displayFieldName" : "PREFIX", "foundFieldName" : "SBL", "value" : "071275", "attributes" : { "OBJECTID" : "1917726", "PARCEL_" : "Null", "PARCEL_ID" : "Null", "PREFIX" : "", "SWIS" : "132400", "COUNTY_SBL" : "00636700000712750000", "SBL" : "071275", "SECNO" : "6367.00", "SID" : "0", "MOD_DATE" : "Null", "CHANGE_DATE" : "Null", "KEYCODE" : "0", "FEAT_CODE" : "0", "PARCELGRID" : "13240000636700000712750000", "SECTION" : "006367", "SUBSECTION" : "0000", "LOT" : "071275", "SUFFIX" : "0000", "KEY_" : "13240000636700000712750000", "GlobalID" : "{420E2C8D-1C3D-4C7D-B1DA-9CA812395C9A}", "Shape" : "Polygon", "Shape.area" : "990788.560251", "Shape.len" : "4266.288356" }, "geometryType" : "esriGeometryPolygon", "geometry" : { "spatialReference" : { "wkid" : 2260 }, "rings" : [ [ [667740.115706164, 1097582.42783179], [667670.516986098, 1097587.4557998], [667670.0025541, 1097681.05451988], [667691.86277812, 1098110.37496828], [667699.407610126, 1098208.84165638], [667837.642618254, 1098225.78335239], [668147.615482543, 1098277.95487244], [668835.092987183, 1098694.60191283], [668871.738107219, 1098435.72421659], [668882.748923227, 1098309.53439247], [668921.141371265, 1097968.72568815], [668874.42700322, 1097930.84434412], [668788.245499142, 1097859.62386405], [668741.724667098, 1097820.36677601], [668699.86047506, 1097784.35474398], [668465.353722841, 1097602.38776781], [668335.335802719, 1097502.60818372], [668261.863162652, 1097447.13106367], [668237.942778628, 1097430.19461565], [668213.807866607, 1097414.88005564], [668183.747322578, 1097398.08082362], [668158.913018554, 1097386.16351161], [668143.091578539, 1097379.4858796], [668121.54738652, 1097371.04978359], [668078.655098479, 1097355.82610358], [668051.233530454, 1097347.65663157], [668040.230266444, 1097344.83141557], [668023.755130429, 1097341.25599157], [668006.068474412, 1097338.18616757], [667936.877050348, 1097327.61643956], [667882.154746298, 1097573.70706379], [667740.115706164, 1097582.42783179] ] ] } } ] });

Message	Solution: add the rings to a geometry object as shown in code below.
	var symbol = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_NONE, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_DASHDOT, new dojo.Color([255,0,0]), 2), new dojo.Color([0,255,0,0.25])); alert(curFeature.geometry.rings[0].length); geometry = new esri.geometry.Polygon(); var rings; rings = curFeature.geometry.rings; for (var r=0, rl=rings.length; r<rl; r++) { //add ring to combined polygon geometry.addRing(rings[r]); } break; } //graphic.setSymbol(symbolfind); map.graphics.add(new esri.Graphic(geometry,symbol));
