Problem with ListGrid inline editing

SmartGWT 2.3, build of 4-Nov

I have a ListGrid where I want to do inline editing (which is by default triggered by a double click, i.e. I do not set explicitly .setEditEvent(ListGridEditEvent.DOUBLECLICK) ). The first time I double click on a row all is working fine and I can see the changes after I exit the inline editor. The second time I double click on the same line I get the following error. Please give me some clue to analyse the problem.

Kind regards.

This looks like a problem that was fixed as of the 8th of November build.
