BeforeRendering Trigger point:

Callstack1:

h就是当前的html document:

Callstack2: 在当前的ui5 document ready之后，执行finishTask操作。

Callstack3: 执行当前ui区域m[i]的rerender 方法:

Callstack4: 调用render manager 绘制JS view:

绘制的位置就是html里面id为content的DIV元素:

Callstack5: render manager 开始render JS view:

就在下面不远处还有AfterRender的callback调用:

Callstack7: JS view instance调用sap.ui.core.mvc.View.onBeforeRendering方法:

Callstack8: fire BeforeRendering:

Callstack9: 和之前的onInit一样，JS view instance调用EventProvider的方法fireEvent来调用beforeRendering callback:

最后application的onBeforeRendering被调用:
