Grid.shiftRow() - row.length != modelRow.length

[jdege@…]

In the function shiftRow(), in Grid.js, I've seen unknown object errors, because the row[] array had one fewer elements than the modelRow[] array.

In the latest instance, prepend = true, modelRowIndex = 0, modelRow.length = 7, row.length = 6.

In the loop, i ranges from 0 to modelRow.length. For the last iteration, i = 6, and row[i] is undefined.

For some reason, every once in a great while, this.grid[0] is an array with one more element than this.grid.pop() is returning.

The result is an unknown object error.
