SERIOUS BUG (I think ...)

If you have only one row on the grid
AND you have only the last cell editable
AND you edit the last cell, then

  • if you end edit with key then all is ok, but
  • IF you end edit with key then you get:

this._getNextCell=function(acell, dir, i){acell=acell||this.cell;var arow = acell.parentNode

“Unable to get value of the property ‘parentNote’: object is null or undefined”

And there is NO way to work around this (for example with try, catch )

It seems there must be some other code or configuration, because the same scenario works correctly locally.
