[Octave-bug-tracker] [bug #29447] Cannot create @handles to non-existing functions

[Judd Storrs]

Follow-up Comment #14, bug #29447 (project octave):

I haven't done Matlab GUI stuff in at least five years, but that's how I
remember it. You create the GUI, open up the parameter panels and enter
callback functions--you can enter strings or function handles but they both
behaved the same. Then you launch the GUI and click around to watch errors
appear in the command window reminding you what needs to be implemented next.
Then you create the missing m-files and repressing the buttons works without
regenerating or reopening the GUI--so yes the handles certainly seem to figure
out that a new file exists.

Let me turn your questions around: 

0 Is it documented anywhere that Matlab does *not* work this way? 
0 Is it important that invalid handles throw errors despite a new function
appearing in the path?

I doubt it because currently invalid handles aren't allowed at all. ;)
