I have a DayPilot scheduler on my app. When I set up the component originally, it is set with cellWidthSpec="Auto" and everything is set fine. I later retrieve my resources via Ajax and set them into the component and update. At this point, the resources are added, but the cells are now scrolling to the right. My users don't want to scroll.
If i resize the browser, then the grid looks as expected, with no scroll bars.
An example (with the problem shown but not fixing when resized) can be seen at http://jsfiddle.net/raedwa01/p7co7ba2/1/
