[Octave-bug-tracker] [bug #49421] Can't set properties in a subclass after chaining constructors in base class

[Ll]

Follow-up Comment #6, bug #49421 (project octave):

Hi, i think i found a related thing, i can confirm the example posted here
keep the derived subclass, so testing i found, if i don't init the subclass
symfun, its created as a sym class....
This don't happen in the examples posted here, but for some reason the sym
superclass overwrite the subclass when the subclass is created (you don't need
call anything, only set it as a superclass).

The super class sym, the same:
https://github.com/latot/octsympy/blob/bug2/inst/%40sym/sym.m
The subclass symfun:
https://github.com/latot/octsympy/blob/bug2/inst/%40symfun/symfun.m

The subclass only print the class of self:

symfun(1, 2)
ans = sym
ans = (sym) 0
 
Examples works:

octave:8> class(derived(1))
ans = derived


Thx. Cya.
