ListGrid startediting problem

[vergillio]

hi

i working with smartgwt 2.2

i develop only client side application in smartGwt

i want to edit last record in my ListGrid, so I call method of ListGrid ListGrid.startEditing(n, 0, false), where n is number of last row, this method create new record and behave exactly same llike method startEditingNew(), but this is not my goal, i just want to start editing last record in ListGrid

i am little confused because when n isnt number of last row and i want start editing any other row, it work fine

thanks for any tips or responses
