If two objects in one czml have different availability, an error will raise.

Hi, All,
If two objects in one czml have different availability, when time move out of availability time of one object, an error will raise.

It said,

An error occurred while rendering. Rendering has stopped.
DeveloperError: This object was destroyed, i.e., destroy() was called. DeveloperError@http://192.168.1.100:8080/Source/Core/DeveloperError.js:37 throwOnDestroyed@http://192.168.1.100:8080/Source/Core/destroyObject.js:44 CompositePrimitive.prototype.update@http://192.168.1.100:8080/Source/Scene/CompositePrimitive.js:410 updatePrimitives@http://192.168.1.100:8080/Source/Scene/Scene.js:828 Scene.prototype.render@http://192.168.1.100:8080/Source/Scene/Scene.js:886 CesiumWidget.prototype.render@http://192.168.1.100:8080/Source/Widgets/CesiumWidget/CesiumWidget.js:537 Viewer.prototype.render@http://192.168.1.100:8080/Source/Widgets/Viewer/Viewer.js:701 render@http://192.168.1.100:8080/Source/Widgets/Viewer/Viewer.js:69

How to set czml value to avoid this?

Thanks,

Can you share the CZML file, or a small copy that reproduces this problem? We have plenty of CZML files with objects that each have of their own availability and they work fine, so there is almost certainly more to it.
