Hi all,

is there any way how to catch which string (construction) is making trouble? Neither trace nor log are concrete:

We try to port OERP 6.1 module to version 7 and subsequently 8.

Thanks a lot for help!

Yes you must avoid the accents in description.  Not so easy sometimes, if your mother language is not english :-) Like me, the hungarian language full fill with accents. (I see this error message daily :-)) )

solution:

  _description = u'Description with é'  

instead of :

  _description = 'Description with é'

I found the solution myself. In fact it was not an issue raised by XML view file but by the .py file itself. Beware - you should restrain using special characters in _descrition section of your class.

Exactly that! A little distraction on accents and a lot of lines of erros. Thanks for share the solution.
