Related question (and yes, I have read the 3.0 blog posts): is there, or will there be, a 2.2 -> 3.0 migration guide? This would be very useful I think. I also have a 2.2 application and would like to migrate to 3.0 because I could use the new features.
Thanks a lot for the enormous amount of work put into 3.0!
I've tried to change my apps to ext 3.0.
Main Problem's i had was with button styling, grid renderer functions and with some menues wich will be dynamicly generated. Menu stuff was because Ext3.0 has a cleanup mechanism wich really destroy all childs of a component...
