You are right, me maybe too - it's matter of taste and the experience level
of users: I've seen situations, where the use of browser's back button produced
very confusing situations, so I prefer to disable uncontrolled step-back
while any edit/insert/delete action.

THAT'S IT !!! (with little limitations) THANKS - I've not realized this
possibility before.
To extract _('messages'), translate and create *.mo files, I can recommend
" poEdit " release 1.3.2 or above, works very well with Python.

Good solution for required message, but ...

... this way seems to be more efficient, because here I can place
translation of all texts + own validators can be extended to range too
(i.e. age field accept values only between 5 to 99, although integer has
other range)

Thank you again for help, if my efforts are successful, I hope to pay
back with posting some usable validators, etc.
