Hi everyone, I have implemented a tapestry-cometd integration
<dependency>
<groupId>org.lazan</groupId>
<artifactId>tapestry-cometd</artifactId>
<version>0.9.17</version>
</dependency>
Our usage of the component is
<t:cometd.PushTarget topic="prop:channelMenuItems"
event="updateMenuItems" update="replace" session="true"/>
and in UAT environment that runs under Tomcat I got the following
exception.
java.lang.IllegalStateException
!session

It is probably worth nothing that this doesn't happen on the first few
triggers of the push event but at some point in the near future.
Has anyone seen something similar before?
