Solutions:
1. Re-download the war from sourceforge http://sourceforge.net/projects/jbpm/files/designer/designer-2.4/
2. Turn off local history feature from $designer-war/profiles/jbpm.xml
3. Turn off local history feature for just one designer window from navigation bar: find the local history icon, there you have the option to turn it off for that process designer window
Background Reason of the problem:
we added local history support, which uses your browser local history to (be default every 1 minute) store your process so you can retrieve any changes later
different browsers have different about of memory of local storage..chrome iirc has like 15mb
so when that fills up
designer shows that message, and clears local storage
now u should not get that every minute, but
there was a bug when i first released the war, and since then updates..so u will still see that message, but it should happen a LOT less..maybe every 2 or 3 hours
depending on if you leave your designer window open
Thanks Tsurdilo,
Hope it helps others who experience the same issue.
