ListGrid Summary Calculation

Hi,

I am using

In my list grid I have Total Column. In this grid I do have showGridSummary=true and set Summaryfunction to SUM. But instead of doing SUM what it is doing taking value from Ist row and doing multiplication with number of row. (Total=3 for Ist Row and have 3 rows then it shows 9 as Summary for that column even Summary Function set to SUM)


In another grid I do have same senario and I am able to show Total Column SUM as Summary In List Grid as expected.

Regards,
