Hi Marcus
Thanks for this, I will add it and wait... because this error is time
delayed it may be a while before it triggers and I reply, but I will.
Thanks again,
Peter

Hi Peter
can you try to set the property
org.apache.tapestry.page-pool-evict-idle-page-minutes to -1? You can,
for example, add the following to your application's hivemind.xml :
<contribution configuration-id="hivemind.ApplicationDefaults">
<default
symbol="org.apache.tapestry.page-pool-evict-idle-page-minutes"
value="-1" />
</contribution>
Does this help?
Marcus

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 :'( Peter

I think you are right - it probably did happen when upgrading from
4.1.1 -> 4.1.2.
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
