标绘功能中画圆结束时出错

[hmilyyang]

看报错信息是因为this._delegate.polygon.hierarchy，对于Circle没有polygon这个属性
尝试将EditCircle.js中_mountedHook函数修改如下可以解决问题：
_mountedHook() {
this._radius = this._overlay.radius
this._center = Transform.transformWGS84ToCartesian(this._overlay.center)
this._positions = [].concat([
this._center,
this._computeCirclePoints(this._center, this._radius)[0]
])
this._delegate.position = new Cesium.CallbackProperty(() => {
return this._positions[0]
})
this._delegate.ellipse.semiMajorAxis = this._delegate.ellipse.semiMinorAxis = new Cesium.CallbackProperty(() => {
if (this._positions.length > 1) {
this._radius = Cesium.Cartesian3.distance(
this._positions[0],
this._positions[1]
)
if (this._radius <= 0) {
return null
}
return this._radius
} else {
return null
}
})
this._layer.entities.add(this._delegate)
}
