afterColumnResize callback can be called with an incorrect size, or undefined

[jasoncrawford]

The afterColumnResize callback can be called with an incorrect size, or undefined, when the resize tab was clicked but not dragged (including times when it is double-clicked to auto-resize).

Repro: See this fiddle: http://jsfiddle.net/XYr2L/

Workaround: this.getColWidth(col) returns the correct width within the callback. Use that instead of the size parameter.

Fixed in HOT 0.9.13. Your fiddle works ok now :) Thanks for reporting!
