[OpenLayers-Users] Node has no parent exception when trying to draw Polygon

[samd]

Hi, I originally had thought this but looking at the drawFeature function of
OpenLayers.Control.DrawFeature on wiki it creates it.

drawFeature: function(geometry) { 
         var feature = new OpenLayers.Feature.Vector(geometry); 
         this.layer.addFeatures([feature]); 
         this.featureAdded(feature); 
     }, 

So here is my code.

         var polygonAreaPoints = incidents[i].areaPoints;
         var pointArray = new Array();
         
         for ( var j = 0; j < polygonAreaPoints.length; j++ )
         {
            var x = polygonAreaPoints[j].x;
            var y = polygonAreaPoints[j].y;
            
            pointArray.push( new OpenLayers.Geometry.Point( x, y ) );
         }
         
         // Create the linear ring
         var ring = new OpenLayers.Geometry.LinearRing( pointArray );
         
         // Create the polygon
         var feature = new OpenLayers.Geometry.Polygon( ring );

         drawFeature.drawFeature( feature );

        Where drawFeature is:

       var drawFeature = new OpenLayers.Control.DrawFeature(polygonLayer, 
                                            OpenLayers.Handler.Polygon, 
                                            {handlerOptions: {'freehand':
false}, 
                                            'displayClass':
'olControlDrawFeaturePolygon'});

Thanks, S.D.
