SAPUI5 in portal, js event disabled with IE 9

The SAPUI5 page is OK in standalone mode.

But When put it in portal as URL iView, the event( button, option) is disabled.

Error in console is:

UI5 runtime is 1.12.1

SCRIPT5007:Unable to get value of the property 'offsetWidth': object is null or undefined
sap-ui-core.js,行91字符58456 (file://0.0.0.0/)
