Autodesk forge 在forge viewer中加载图钉不符合viewerState

我们正在forge viewer中使用“Autodesk.BIM360.Extension.PushPin”扩展来启用图钉

将图钉添加到模型后，我们序列化图钉数据并将其存储在数据库中。此类图钉的示例如下：

}

然后在稍后（当用户重新打开模型时）再次将图钉加载到模型中，如下所示：

pushPinExtension.loadItems([pushPinItem]);

结果是图钉添加到模型中的正确位置，但查看器状态不正确。似乎图钉的查看器状态设置为加载图钉时模型的查看器状态，而不是存储在图钉内的查看器状态

这是预期的行为吗？-如果是这样，我如何使用图钉中的查看器状态呢？

为什么不在加载图钉后分别显式加载存储在图钉中的查看器状态：

pushPinExtension.loadItems([pushPinItem]);
viewer.restoreState(pushPinItem.viewerState)

编辑：

尝试在单击项目时还原查看器状态-使用以下内容订阅单击事件：

   viewer.restoreState(...)
   //...
})

谢谢你的快速回复，布莱恩！不是在加载图钉时恢复viewstate，而是在用户单击图钉后恢复viewstate。现在发生的情况是，当单击任何问题时，相机会移动到“初始”视图，如我的问题中所述。我确信我会知道这是一个问题，希望他们能很快解决该问题-同时，单击项目时，您可以恢复查看器状态-请参见编辑
