I'm just preparing a ToDo example to show the another and currently the
strongest dimension: highly ajaxified and realtime so called single page
apps. What you saw in tutorial is a traditional but still very needed
approach. Combined with single page one you come to the biggest strength
of Aida.

Change method name to #actionMainBack

And change this method name to #actionMainEdit.

As you see action method names are composed by convetion as
'action'+viewname+action(optional). That's why #actionMainBack.

Let me add an error report if such method is not composed correctly and
therefore missing...

Best regards
