Hi,
Before I submit this as a bug, I wanted to check if anybody else had the
same issues and/or knows what could be the cause of this:
Once in a while, I get reports from users who get errors from the
editwizards when editting a node. After restarting mmbase, the problem
goes away and the same node that was causing errors works again.
The errors are usually something like this:
org.mmbase.applications.editwizard.WizardException: Errors received from
MMBase Dove servlet: Node was changed in the cloud, node number : 102610
field name linktext
(complete stack trace below)
>From Dove.java I understand this happens when a node was changed during a
transaction. What could be causing this? How can I prevent these errors?
I'm using mmbase 1.7.3 btw.
The complete stack trace:
org.mmbase.applications.editwizard.WizardException: Errors received from
MMBase Dove servlet: Node was changed in the cloud, node number : 102610
field name linktext
