Hi all,

I am very new to ZK framework and I am in the process of upgrading ZK from 3.0.7 to 8.

But, I am facing the below error after I replaced the jars and server restart.

Blockquote Warning: Unexpected error forwarding or redirecting to login page java.lang.InternalError: Not possible: <window nz8ql#login=""> at org.zkoss.zk.ui.sys.HtmlPageRenders.outStandalone(HtmlPageRenders.java:956) at org.zkoss.zhtml.impl.AbstractTag.redrawChildrenDirectly(AbstractTag.java:300) at org.zkoss.zhtml.impl.AbstractTag.redraw(AbstractTag.java:272) at org.zkoss.zhtml.impl.AbstractTag.redrawChildrenDirectly(AbstractTag.java:296) at org.zkoss.zhtml.impl.AbstractTag.redraw(AbstractTag.java:272) at org.zkoss.zhtml.Body.redraw(Body.java:47) at org.zkoss.zhtml.impl.AbstractTag.redrawChildrenDirectly(AbstractTag.java:296)

Am I missing anything? It would be great if anyone can shed some light on this.

Thanks, Vashni

you are taking a big jump here. ZK isn't backward compatible so there are a lot of things changed. I suggest doing the upgrade in steps. Try first ZK5, then ZK6 and at last ZK 8. (6 and 8 have lot of major changes) You definitely need to do some refactoring on the code.

Hello Vashni,

It's amazing how much zk has grown since the version you are using is from 2008!

As an addition to chillworld the best thing you could do now is to study the documentation, understand the logic of your application and start migration components to ZK8.

It will take a while but the benefits will be big!

Best Regards,

Darksu

Hi Guys,

Thank you very much for your replies. Currently I am trying to understand the current ZK framework and planning to proceed forward.

Thanks, Vashni
