Hi Dennis , 
thank you for your answer.
with this i don't have any more the exception.
but , it seems to me that i have a mistake in my configuration file ...
some panels appear even if I do not want that they appear ...
please , can you cheque for second once  my conditions.xml file , and tell
me if  there are other things to change. ( the manner that i use for not ,
ref ... is correct ?)
A+
