Challenges when upgrading from Ext JS 3 to Ext JS 4

I am looking to upgrade my code from Ext JS 3 to Ext JS 4. I used the Ext.Updater class in Ext JS 3, but I cannot seem to locate a similar functionality in Ext JS 4. Can anyone provide assistance with this transition?

Answer №1

While there are no guarantees of a seamless migration, if you are determined to proceed, you may find helpful insights in this comprehensive guide.

Answer №2

Check out Ext 4.x's Ext.ElementLoader, which has the ability to update elements using ajax calls as well. Make sure to take a look at it.

I hope this is what you were searching for.
