Re: [xwiki-users] Hibernate bug while trying to save modifications

Hi all, I found a really annoying bug today, and I am really lost solving it : I have created an application based on xwiki, i tried it on 3 different test servers, using the export import between each server. My application generate a lot of pages/objects. When I use the export/import between the servers, I import only the application, not the data. Everything worked fine, but I imported the application on the prod server friday. Since then, I can create an object. When i try modify it, I have the following error and stack trace : A problem occured while trying to service your request. Please contact the support if this happens again. Detailed information: Error number 3201 in 3: Exception while saving document Project.0,0,0,3,0 Wrapped Exception: Row was updated or deleted by another transaction (or unsaved-value mapping was

java.lang.Thread.run(Thread.java:619) I can create and modify other kind of objects generated by this application without any problem. In the history of the page/object, I have a version 1.1 created by me before the import on the wiki (the objects have been created today, the import was friday). I am not admin on the server, but the last test was on another instance of xwiki on the same server and the configs are the same. Did somebody already have this problem ? How can I solve that ? Thanks in advance. Jean
