无限循环似乎导致从交叉相关的视图

Question

在我的图形应用程序，我有一个功能，所有页面导出为图片，我有这样的例外，我不知道从哪里开始寻找解决这个问题：

An infinite loop appears to have resulted from cross-dependent views. 

任何人都可以帮助我理解这个例外吗？如何解决它？或者是什么导致了这样的崩溃？

这里是堆栈跟踪：

Answer 1

那么有没有很多去没有任何代码来看看，但无论如何，我会试一试。

的第一步是使视图较少依赖于彼此。也许有一个他们都在看的模型，而不是让他们看着对方。

另一个步骤可以使更新代码只在需要的时候做一个更新。有时候，当我有改变另一个控制的控制，我把在逻辑来更新它当其他控制的变化，我发现，当真正需要没有改变我的更新的东西被调用。例如，如果某个事件导致控件大小调整，则可能需要计算新值，然后只在实际更改大小属性时才更改大小属性。 （即：是不一样的新值）

希望这可以帮助...
