Full Error Text
cannot get grid to draw rows when it is in the middle of drawing rows.
Your code probably called a grid API method while the grid was in the render stage.
To overcome this, put the API call into a timeout, e.g. instead of api.redrawRows(), call setTimeout(function() { api.redrawRows(); }, 0).
To see what part of your code that caused the refresh check this stacktrace.
