Hum, I may not have a complete understanding of optimistic locking. Bottom line is that when someone wants to start editing, I want them to know before they start if someone else is already in the midths of editing a given item. I do not want to just hope that two people never edit the same thing and if they do error out on the last to try to save if they didn't have the right starting version. It seems like that is what could happen in the optimistic approach but I could be wrong as I have never used the approach. I will study the LockMode.UPGRADE, but if it doesn't give me a way to give user feedback when someone else is in edit "thinking" mode, I don't think I would use it. -- View this message in context: http://www.nabble.com/Dirty-read-edit-problem.-tp24157057p24157353.html Sent from the Wicket - User mailing list archive at Nabble.com.
