Hi !!!
I suggest that future versions of ExtJS, multi applications are implemented MVC architecture instances.
That is, an application is composed of bundles, these are themselves applications.
I leave you a short demo as an example of multi-instance application.
Can one of you please share some reference link to those examples or reference?
We wanted to develop each module like user manager, item manager, invoice manager etc as an application with model and store (MVC) using Sencha Architecture v2.x and wanted them to work these application in tab in our deskboard application with click of selected menu item.
