The below labeling code is working for polygon layer (created dynamically) but not the point layer(created dynamically).
var statesColor = new Color("#060606");
var statesLabel = new TextSymbol().setColor(statesColor);
statesLabel.font.setSize("12pt");
statesLabel.font.setFamily("arial");
var json = {
"labelExpressionInfo": {"value": "{ENTITY_FIELD}"},"labelPlacement":"above-right"
};
var labelClass = new LabelClass(json);
labelClass.symbol = statesLabel;
this.temporalLayer.setLabelingInfo([ labelClass ]);
this.map.addLayer(this.temporalLayer);
Complete code for point layer is below . The dynamic layer is geographic coordinate system .
