Hi,
i have a strange problem with zk and this line:
arg0.setAttribute("SKIN", currentSkin);
this line is called from:
public class SessionManager implements org.zkoss.zk.ui.util.SessionInit{
public void init(Session arg0, Object arg1) throws Exception {
and it seems call a new session every time and so it cause a stack overflow..
i did'nt see this in the past. Actually i'm using zk 5.0.9 anyone?
i've cut a lot of text.. but you should see that my line
at com.wsm.framework.SessionManager.init(SessionManager.java:33)
cause the problem

It also happened to me; I couldn't find out why, but I was able to manage it with the following (obvious) scheme:
public void init( Session sess, Object request ) throws Exception {
if( sess.hasAttribute( ALREADY_INITIALIZED ) ) {
return;
}
sess.setAttribute( ALREADY_INITIALIZED, Boolean.TRUE );
...
}With kind regards

I've seen this too with 5.0.9 and fixed it similarly as César.
It's probably a pretty new ZK bug because my code worked with older versions correctly.
Hi,
Could you kindly provide a sample that can reproduce this issue and post a bug on bug tracker?
Thanks,

We had a similar problem, and the solution we chose was simply to extend org.zkoss.zk.ui.http.HttpSessionListener like this:
public class HttpSessionListenerEx extends HttpSessionListener {
@Override
public void attributeAdded(HttpSessionBindingEvent evt) {
if (!shallIgnore(evt.getName())) {
super.attributeAdded(evt);
}
}
private boolean shallIgnore(String name) {
// ignore javamelody session activation attributeAdded event if current session is not known
return Sessions.getCurrent(false) == null && "javamelody.sessionActivation".equals(name);
}
}
"javamelody.sessionActivation" here being name of the session attribute in question
