 it works as you said (with 1.9.90, with 1.9.50 I can not get the children
of MyFileView), there was only one sentence missing in the _new procedure:
me.Children[0].drop=true
 to make it work.

In fact, I didn't need to create a new class subclassing FileView, just
adding the observer to an existing FileVIew in the form is enough.

Thanks very much for your support and ideas. It's at least as valuable as
your developing work.
Regards.
