Hi I remember that one. Take a look at this one: http://issues.apache.org/jira/browse/MYFACES-2165 A patch was applied, so the solution is included in 1.1.7 and 1.2.7. It could be good to have confirmation that solution solves the problem (I haven't close that one yet by that reason). regards Leonardo Uribe > > Thank you for your notice. > > Cheers, Matthias. >
