Hi everyone

I have a environment with ZK 5 and Tomcat 7. I need to get a session replication using memchaced and memcached-session-manager(msm). I'm using kryo like serilization method with msm.

Right now, I have an issue using the ZK components. When I do click over some radio for example, I'm getting a alert message saying: "" and the buttons resend and cancel. So I will never able to advance to the next actions o request for server.

I have the next configuration in $CATALINA_BASE/conf/context.xml for msm:

<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
        memcachedNodes="n1:192.168.56.101:11211"
        sticky="false"
        lockingMode="all"
        sessionBackupAsync="false"
        transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"
        requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$" />

I have all required libs in my tomcat libs according with msm documentation.

In another hand, I have the next configurationm parameters in my project's zul.xml:

<system-config>
        <disable-event-thread/>
        <ui-factory-class>org.zkoss.zk.ui.http.SerializableUiFactory</ui-factory-class>
        <id-generator-class>com.pagosonline.ppp4.web.common.zk.utils.ZkIdGenerator</id-generator-class>
        <disable-zscript>false</disable-zscript>
    </system-config>

    <session-config>
        <session-timeout>1800</session-timeout>    
        <timer-keep-alive>true</timer-keep-alive>
        <timeout-uri></timeout-uri>
    </session-config>

In the tomcat logs, I've seen that memcached service takes the id session correctly, but when I try to do something that involves zk components or events, I just get the message mentioned earlier.

I hope you could help me soon with this issue.

Thanks in advance.
