Page deserialization problem after a network problem
Sometime our customers have network problems (e.g connection interrupted
for a short period) and if that happens when we are sending response for a
page, an exception is thrown:
*2020-04-23 18:47:28 ERROR [ba00c0b5f1c83a39/ba00c0b5f1c83a39] [00529169]
[m00080874] DefaultExceptionMapper:144 - Connection lost, give up
responding.org.apache.wicket.protocol.http.servlet.ResponseIOException:
org.eclipse.jetty.io.EofException*
which is normal.
But after that if a user tries to do something else in the same page (e.g
clicks on an Ajax Link) a deserialization error appears (like stack trace
below).
Did anybody else encounter the same behaviour?
We are using Wicket 7.10.0 and do not understand:
1. why serialized page contains information (details of connection
exception) when serialized
2. why EofException is not found during deserialization, since it was
thrown seconds before in the same running JVM

Found the problem. Mainly we had stored in session the last exception
encountered.
Will remove that code and hope this exceptions are gone.
Thank you for your support.

Re: Page deserialization problem after a network problem
Posted by Sven Meier <sv...@meiers.net>.
Hi,
I don't understand how that exception ends up in your component
hierarchy either.
Do you use a custom exception mapper or listener? I don't see any place
in Wicket where that exception is stored.
Best regards
Sven
