In my current project need to extend an already existing controller.
I tried with the usual way: drag & drop then select "link".
After that I cant select application node (TypeError: 'undefined' is not an object) and derivated controller shows no code and there is nothing I can do with it.
Obviously controller inheritance is not supported and designer allowed me to d&d because (I guess) is a core functionallity.
Controller inheritance will be supported?
Window can be extended
Windows can't be extend.
This is the scenario:
I'm working in a wizard window in MVC way: view + controller.
But I realized that I will need another wizar window. Instead of copy/paste controller's flow code I tried first to extend a "Wizard controller". But I found that is not possible to do that. So I decided to create a "Window wizard" with all visual elements (title & toolbar) and flow code (inside the view) and via custom property the name of the xtype which contains the wizard pages. But I found that Windows can't be extend.
What is the reason Window can't be extended?
You should not be able to drag an existing controller to the controllers node and then drop it.
Controller inheritance may be supported in the future but will not be part of our 2.0 GA release.
