    Default Upgrading from 4.0.7 - 4.1.3

    Upgrading from 4.0.7 - 4.1.3


    Hi,

    I'm considering upgrading my app from Ext 4.0.7 to the latest version 4.1.3. This is primarily because of some grid scrolling issues and performance problems I'm having in 4.0.7.

    Just swapping over the version of Ext didn't seem to work well - a lot of errors! I was just wondering if anyone else had been through this process, and what problems I am likely to encounter. Also, I'm wondering how much faster the latest versions of Ext actually are - is it worth putting in the effort to upgrade?

    Thanks in advance for your help!

    It is well worth the effort! The errors are dependent on your code. I would use ext-dev.js to display warnings in your console to help resolve the issues. Once these have been updated, you should be closer to getting things working as expected.

    4.07 was a bit of a mess and allowed bad behavior. It is highly recommended that you upgrade.
    The performance is better as well.

    Regards,
    Scott.
