I have got 3 classes that form a hierarchy (see attached .tgz file):

baseobj
 derivobj - based on baseobj
  deriv2obj - based on derivobj

when I try to create two or more instances of deriv2obj, only the first one is created, afterwards octave returns an error message:

octave:2> d21=deriv2obj

d21 =

deriv2obj object: 1-by-1
derivobj object: 1-by-1

  scalar structure containing the fields:

    val =

  scalar structure containing the fields:

    extra =
    {
      [1,1] =
    }

  scalar structure containing the fields:

    extra2 =
    {
      [1,1] =
    }

octave:3> d22=deriv2obj
error: class: `derivobj' is invalid as a class name in this context
error: called from:
error:   /home/volkmar/octave/@derivobj/derivobj.m at line 51, column 6

Also, although d21 was displayed just fine after creation, I can't display it anymore after trying to create d22:

octave:3> d21
error: display: not defined for class "deriv2obj"
error: called from:
error:   /export/spm-devel/octave/octave/scripts/general/display.m at line 37, column 5
octave:3> whos d21
Variables in the current scope:

  Attr Name        Size                     Bytes  Class
  ==== ====        ====                     =====  =====
       d21         1x1                          0  deriv2obj

Total is 1 element using 0 bytes
