ConcurrentModificationException while serializing a page
--------------------------------------------------------
Key: WICKET-2756
URL: https://issues.apache.org/jira/browse/WICKET-2756
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.3.7
Reporter: Hans Bausewein
Attachments: concurrentmodificationstacktrace.txt
The ConcurrentModificationException could be due to some change in my
implementation of the Page, while it was being serialized.
I'd like to report it here, though, because it is an issue with the model that
Wicket uses.
I'd recommend to update the documentation with some restrictions on what can be
in pages.
Preferably use only immutable objects, no weak references or anything that
could possibly be changed.
It's quite difficult to find out what was changing which object, here.
According to the stack trace the length of a list changed.
I have checked the logs of the past half year and have not found a single other
case with the same signature.
