Bug & Problem setShowGridSummary

[wonderman882]

Hi,

I use the setShowGridSummary as following.

listGrid.setFields(listGridField, ...);
lisGrid.setCanRemoveRecords(true);
productsListGrid.setAutoSaveEdits(false);

listGrid.setSummaryFunction(SummaryFunctionType.SUM);
listGrid.setShowGridSummary(true);

As I add new record with entering number OR we edit existing data on listGrid. The Grid Summary work as normal.

However, if I remove one record. Then the Summary should be changed but it can not.

Have I miss any setting or it is a bug on ListGrid ???
Thx for your help.
