Is there a migration path defined for those of us who've made use of Ext.ux.tree.ColumnTree?
The alternative that we had previous set aside (for performance reasons, if I remember correctly) has been pulled into the core code ("Ext.ux.tree.TreeGrid is no longer a Ux. You can simply use a tree.TreePanel").
What about ColumnTree? A great deal of code has been built upon this implementation, and I'd love to hear that a migration path exists. Otherwise, we have to migrate it ourselves or move to the new TreePanel implementation.
Thanks in advance.
