Parameterized constructors and inheritance

Hi, guys.

I am trying to create a non visual object with a parameterized constructor.

Suppose this following situation:

1)  I've created 'nvo_test1' with a parameterized constructor:

2)  Next, I've inherited 'nvo_test2' from nvo_test1. I still see the constructor there:

3) When I create another level of inheritance, 'nvo_test3'  the constructor event is not available anymore.

So, I am about to guess that Powerbuilder doesn't love me anymore , unless someone has a brilliant guess to this problem.

Any help would be great, thank you
