Adding row to a ListGrid at a specified index Smart GWT

Question

Currently I'm working on a listgrid which is editable and my requirement is to create a a new row every time a user selects a row and presses the "Create" Button. The new row needs to be added immediately below the selected row. I tried using the below method

ListGrid.getRecordList().addAt(ListGridRecord rec, Index index)

However I got the warning message

15:48:04.373:MUP3:WARN:Log:ResultSets are readonly. This operation (addAt) will be ignored.

I've searched the smartgwt showcase to look for ways to edit a grid , so that new row is added at a specified index, however I wasn't able to find anything suitable.

I got to know that ResultSets is getting created because I'm using the statement ListGrid.fetchData() Is there any way to solve this issue? Any suggestion is highly appreciated!

Muchas Gracias.

Figured it out, quite a weird trick...but works for me... what you need to do is use grid.setRecords(grid.getRecords()); just before grid.getRecordList().addAt(rec, index); I think doing this makes the ResultSet editable.
