This might be the same as this viewtopic.php?f=43&t=14380 but my configuration is a bit different so I figured I would make a new post.
Issue seems to be with finalizeCellEdit + triggerEvent = cellclick.
To replicate, go to the cellEdit demo and change:
cellEdit : true,
to:
cellEdit : { triggerEvent: 'cellclick' },
Then click to edit the Start Date cell, change the value, then click on another cell in the Start Date column. That's when I get the onEditorComplete error.
Hopefully that makes sense.
Thanks,
Tim
