Eric
thanks. I saw some postings for this yesterday but did not get it to
work, and thought it might not be fully functioning... Now I tried again
- and succeeded... ;-)
I could overwrite the function by adding the complete original code and
afterwards the lines I needed for extending it. But I did not find any
possibility to make a call to the original initialize function and then
afterwards just the few lines to extend the function. But maybe this is
not possible.

The overwrite function and its associated test functions in the IGN
section of the Class tests may help you. See
