well, that's clear. You're having a select field here and 
"Project->list;Project->exportProjectList;..." is your select key. Now 
you changed the select key for that option and the previously stored key 
is now a "invalid configuration" because the key doesn't exist anymore. 
You have to reselect the "Project" option and save the flexform in order 
to apply your new configuration.

The "view not found error" is displaying the name of the action/view it 
tried to render at the end of this message. Which view is mentioned 
there, and have you also renamed your templates itself as well as the 
action names used inside the templates according to your new action 
names? If not, that's your problem.

that's not configurable. If the action is present in your controller 
(like you confirmed below) it still can be called (if allowed), so you 
won't see an exception.

If you're accidentally triggering your old action name and it still 
exists and is callable (public and not private) the action will be 
called. And if there is no template available for that action you'll get 
the "view not found" message.
