EllipsoidGraphics.maximumCone cannot be dynamic

[hanyingling]

在cesium1.62 , EllipsoidGraphics.maximumCone 使用 new Cesium.CallbackProperty不起作用?
例：
var viewer = new Cesium.Viewer('cesiumContainer');
var i = 50;
var entity = viewer.entities.add({
name : 'Dome with inner radius',
position: Cesium.Cartesian3.fromDegrees(-114.0, 40.0),
ellipsoid : {
radii : new Cesium.Cartesian3(1000, 1000, 1000),
maximumCone :new Cesium.CallbackProperty(setAngle, false),
material : Cesium.Color.RED.withAlpha(0.3),
outline : true
}
});

function setAngle() {
//只走一次
if(i>0){
i-=10;
}
return Cesium.Math.toRadians(i);
}

viewer.zoomTo(viewer.entities);
请问怎么解决这个问题

Thanks @HuZhuangQiang . I can reproduce this. Here's a Sandcastle where the ellipsoid will pulsate by changing its radii, but the cone angle won't change from the initial value set (so if you change the Math.sin to Math.cos in the setAngle callback it'll have a different initial value).

I think the maximumCone property just needs to be wired up here to detect updates to it and make sure the new value is used?

does that sounds right @hpinkos ?
