Grid Components for Select Item

Hi,

I have a problem with Select Item having Grid Embibed as Picklist property.

The only problem I have is, I am using Grid components and in which I am not able to get Grid Summary row in that.

This was working until upgrade my smart GWT from 4 to 5.
So in this Latest SmartGWT 5 version I could not get Grid Summary for Select Item.

Please help me in this.
Thank you in advance.
