Hi Jessie,
Thanks for your reply.
I don't think this problem relates to OGNL... The thing is that these
classes are pretty ordinary page classes with Strings and Integers,
really nothing special, and besides it works great for a while, and then
after a random period it gets confused? which tells me it's not OGNL
related. The bug is very difficult to reproduce because it happens after
a random period of normal activity. When it breaks though, all page
classes seem to break. My guess is that the error occurs either after
garbage collection or a servlet exception, and may relate to class
reloading somehow.
Stopping and starting the servlet corrects it... I'm very confused :'(

I think you are right - it probably did happen when upgrading from

I changed a few things wrt OGNL and this is probably something related.
If you file a re-produceable bug report here
http://jira.opensymphony.com/browse/OGNL I will look in to it.
(re-produceable meaning that I have the ability to re-produce your
error exactly by knowing the object types (exact) and values involved
in whatever expressions aren't compiling.
Haven't heard about classes disappearing before so not sure what that
is. The Tapestry 4.1 demos all run on 4.1.2 / tomcat.

Hi All,
Can anyone help me to understand what's going on here... I run my servlet on
Tomcat, it works great for a while, but then some classes seem to disappear, or
at least they cant
be found by Hivemind, and the log fills up with errors like this one:
org.apache.hivemind.ApplicationRuntimeException: Unable to add method
java.lang.Object get(ognl.OgnlContext, java.lang.Object) to class
$ASTProperty_11488aa7b43:
[source error] no such class: $RiskModel_61
Caused by: javassist.CannotCompileException: [source error] no such class:
$RiskModel_61
What is javassist doing and why cant Hivemind find my classes any more? This
error has appeared since upgrading to 4.1.2 from 4.1.1.
Kind regards
Peter
