Issue related to the behavior change for DateTimeItem Picker.

Hi,

We notice a behavior change for the date-time picker of DateTimeItem. Previously when we click a date in the picker, the date is chosen and the picker is closed. However, currently clicking a date won't close the picker and we need to click the "Apply" button to close the picker.

It works fine on SmartClient_v91p_2014-09-16_PowerEdition but changes on SmartClient_v91p_2014-11-25_PowerEdition

This behavior change fails many test cases in our product. Is there any property/way to get back to the previous behavior?

This issue can be reproduced on any DateTimeItem:
1. Click icon to show the picker.
2. Click a date in the picker.
In previous build, the date get selected and the picker closes. But now, it doesn't close after clicking a date.

Thanks!
Robin
