nite_man has asked for the wisdom of the Perl Monks concerning the following question:

Hi,
I have a very strange (at least for me) problem with OO Perl. I have following hierarchy of classes:
Class A is base class, class B is a child of A, class C is child of B. Each class has its own list of fields which should be merged in case of object C. It works fine but in one case (it's application specific case, so, I cannot put there the code) when object C is created only its fields are in the %FIELDS.
Does somebody has some idea why it happens?
Thanks in advance.

    Without seeing any code, it's impossible to give any reasonable level of help. Would it be possible for you to create a cut-down but complete example that exhibits the problematic behaviour that you describe?

      I agree with with you but the problem is when I try to reproduce this problem using some simple case, let say, create a scrit and create the object C there, everything works fine. But if I get you the code it takes 5 - 10 screens and week to understand how it works.
      Maybe you have some suggestions how to trace it?

        Well, if you have a cut-down version that works and a full version that doesn't, then why not start with the cut-down version and slowly add code from the full version until it breaks.
