Hi, I'm a user of the dedicated xwiki farm for Java User Groups. I have a noticed a very strange problem. I have created a form linked to a class. With this form I create and save some data. I have also told to users of our web site to create data (it is something like a registration). When I come back to my pages few days later, some of the data previously recorded are lost. Is there a problem of data saving (problem with hibernate sessions, ...) ? Zouheir CADI, Paris JUG Leader
