Show Technical Document Details
In Dashboard, changing the value of "Messages to Show" of MESSAGES is not completed. Eventually, the widget is not refreshed.
The problem is specific to IE (even if in compatible mode).

But, this is not observed in API Portal v3.5 GA (non-CR).

Gear button: /ajax/manage/widget-config
Done button: /ajax/manage/widget-update

-Reproduction Steps
1. start IE .
2. login to Portal admin.
3. in Dashboard, click Gear button of MESSAGES widget. (/ajax/manage/widget-config)
4. change the value of "Messages to Show".
5. click Done button. (/ajax/manage/widget-update)

Result: the value is not changed nor widget is not refreshed.

-Desired Behavior
widget-update should be completed and the widget should be refreshed.
API Portal v3.5 CR09
This is a defect in CR09, specific to IE only.
The problem will be fixed in future CR.

As a workaround, use other Web browser in the mean time.
