    Included in 3.1

    In Extjs 3.1 blog it says:

    The treegrid is not included in the base of the 3.1 download. The example is still being linked to a set of extension (ux) js files. Is this a mistake?

    Thanks.

  14. That worked

    That is a great workaround. That solves the issue for now. I wonder if there is a method the HtmlEditor needs to override so the Iframe doesn't get messed up on animation.

    Thanks for the tip.
