Hi all, I am trying to create a polygon on my view from click points, I take the point and add it to a point collection, then I calculate the rings for the polygon. I am able to create the polygon with hard coded rings, like in the esri examples, but when I build the array of rings programmatically, it doesn't draw. I don't get any errors, the polygon just doesn't draw. I am building the array as an array of objects, I logged the hard coded array to the console to see what the exact structure was, then I created that programmatically. If I am overlooking something, I can't think of what it could be, the functions are exactly the same, except for the rings assignment.
function putIDBoxOnMap() { //draws polygon
var polyID = new Polygon({
spatialReference: view.spatialReference,
rings: [
[750916.6634999937,856041.7037500741],
[757750.010500021,856291.7042500751],
[758416.6785000238,852375.0297500595],
[751666.6649999968,851791.6952500571],
[750916.6634999937,856041.7037500741]
]
});
console.log(polyID.rings);
polygonGraphic.geometry=polyID;
polygonGraphic.symbol=simpleFill;
view.graphics.add(polygonGraphic);
}
This is the logged array from this function:(I only expanded one of the vertices to save space)
750916.6634999937,856041.7037500741,757750.010500021,856291.7042500751,758416.6785000238,852375.0297500595,750916.6634999937,856041.7037500741

],

2: [ ],
3: [ ],

length: 1
]
function putPolyOnMap() { //does not draw polygon
var pRings=[];
var pPtXY=[];
for (i=0;i<ptCount;i++) {
pPtXY[0]=ptColl.x;
pPtXY[1]=ptColl.y;
pRings=pPtXY;
}
pPtXY[0]=ptColl[0].x;
pPtXY[1]=ptColl[0].y;
pRings[ptCount]=pPtXY; //closes the polygon
var pRingsAll=[pRings];
var idPolygon=new Polygon({
rings: pRingsAll,
spatialReference: view.spatialReference
});
console.log(pRingsAll);
polygonGraphic.geometry=idPolygon;
polygonGraphic.symbol=simpleFill;
view.graphics.add(polygonGraphic);
}
});
Returns this array.
743749.9824999651,857375.0397500795,743749.9824999651,857375.0397500795,743749.9824999651,857375.0397500795,743749.9824999651,857375.0397500795

I cannot see any difference in the structure of these arrays.
Thank you in advance for any help you could provide.
