Hi Darksu,

Unfortunately the problem is not solved yet. On ZK 7.0.3 doAfterCompose is not invoked on any page. I currently try to launch my applicaion on 5.0.12 - I managed to do it by removing <include src="menu.zul"/>, but the functionality seems to be partially broken (some properties of ZK tags do not work, I got "Unknown idspace: null" exception occasionally, etc.). I tried on different workspaces (and computers), on Tomcat 6 and 7 - everything is the same. I have to use Java 1.6, since production servers have this version.

I can't upload the project - it's too big and is a commercial one. However this is what I found: the zul in "include" tag contained zscript code that used some object, initialized in composer - and this code was launched BEFORE composer code. That lead to null pointer and crash. I'm new to ZK and for some reason I was sure that doAfterCompose is invoked first (in previous version it was so, I think). So, is it possible that zscript code in included zul is launched before the composer, applied to the page with "include" tag?

    <zscript>
      <![CDATA[
        import java.util.*;
        import myproject.web.menu.*;
        import org.springframework.security.context.*;
        ProjectMenu menu = (Project) session.getAttribute("PROJECT_MENU");
        List items = new ArrayList();
        if(menu==null){
            ProjectMenuItem item = new ProjectMenuItem(null, null, null);
            items.add(item);
        } else {
            items = menu.getSelectedPath();
        }
        ]]>
    </zscript>

The check for "menu=null" is added by me to avoid crash - initially it just called the "getSelectedPath" method. The ProjectMenu object is initialized and saved into session in composer.
