I hope this is a bit related to you problems:
In KexiDialogBase, I've reimpelmented KMdiChildView with KexiDialogBase 
and I am calling KMdiChildView::activate() when needed, look here:

http://webcvs.kde.org/koffice/kexi/core/kexidialogbase.cpp?rev=1.108&view=markup

Also look at KexiDialogBase::addView() - setting focus proxy can help 
with focusing.
