I am using Multi-Grouping with Checkbox plugin.
When I select checkbox, it's duplicating the row. Whereas when I use basic grouping (single grouping) it works fine.
The issue is at refreshRow (Line #33614 approx) - ext-all-debug.js - According to me
this.insertRows(ds, index, index, true);
this.getRow(index).rowIndex = index;
Please help or guide.
Thanks in advance for your help.
