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:
Callstack6: 在render manager的实现里，首先掉beforeRender的callback:
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:
