Hi,
first of all zul is great. But I have a problem about accesing the object within JSP. Let me explain:
1. The main jsp page (main.jsp) looks like :

<%@ taglib uri="http://displaytag.sf.net" prefix="display" %> <%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%> <%@ taglib uri="http://www.zkoss.org/jsp/zul" prefix="z" %>

<z:page>
<z:window id="mainWindowID" border="normal">
<z:div id="issueBaseEditInitiator">
<z:include src="/view/plm/issue/issue/main/edit/zul/EditAffectedParts.zul"/>
</z:div>
<z:div id="issueInformation">
<z:include src="/view/plm/issue/issue/main/edit/zul/IssueInformation.zul"/>
</z:div>
<z:div id="issueUnit">
<z:include src="/view/plm/issue/issue/main/edit/zul/IssueUnit.zul"/>
</z:div>
</z:window>
</z:page>

2. And EditAffectedParts.zul. The code looks like:
<?init class="org.zkoss.zkplus.databind.AnnotateDataBinderInit" ?> <?init class="com.ps.action.plm.issue.main.edit.zul.IssueBaseEditInitiator" ?>

<window id="issueBaseEditInitiator" title="Affected Part(s)" border="normal"
onCreate="self.onCreate()"
use="com.ps.action.plm.issue.main.edit.zul.IssueBaseEditInitiator"
onClose="self.visible = false; event.stopPropagation();"> <hbox>
<label value="Part #:"/>
...................
...................
...................
</hbox>
</window>

the java code is (IssueBaseEditInitiator.java) :
public class IssueBaseEditInitiator extends Window implements Initiator{
public void onCreate() {

}

public void onOpen(){
}


public void doAfterCompose(Page arg0) throws Exception {
// TODO Auto-generated method stub

}

public void doCatch(Throwable arg0) {
// TODO Auto-generated method stub

}

public void doFinally() {
// TODO Auto-generated method stub

}

public void doInit(Page arg0, Object[] arg1) throws Exception {
}

public List getAffectedParts() {
return new ArrayList();
}
}

3. and IssueInformation.zul looks like EditAffectedParts.zul. It also has the java class named IssueUnitInitiator.java.

<?init class="org.zkoss.zkplus.databind.AnnotateDataBinderInit" ?> <?init class="com.ps.action.plm.issue.main.edit.zul.IssueUnitInitiator" ?>

<window id="issueUnitInitiator" title="Affected Part(s)" border="normal"
onCreate="self.onCreate()"
use="com.ps.action.plm.issue.main.edit.zul.IssueUnitInitiator"
onClose="self.visible = false; event.stopPropagation();"> </window>


here is my question:

at IssueInformation.zul, or at IssueUnitInitiator.java or at main.jsp I want to able to use/reach the the Window object of EditAffectedParts.zul which ID is issueBaseEditInitiator.

for example at IssueUnitInitiator.java:

public class IssueUnitInitiator extends IssueBaseEditInitiator{
public void onCreate() {
}

public void onOpen(){
}


public void doAfterCompose(Page arg0) throws Exception {
// TODO Auto-generated method stub

}

public void doCatch(Throwable arg0) {
// TODO Auto-generated method stub

}

public void doFinally() {
// TODO Auto-generated method stub

}

public void doInit(Page arg0, Object[] arg1) throws Exception {
}

public void getUnits(String unitName){
HttpServletRequest request =
(HttpServletRequest)Executions.getCurrent().getNativeRequest();
IssueBaseEditInitiator win =
(IssueBaseEditInitiator)request.getAttribute("mainWindow");
List affectedParts = win.getAffectedParts();
}
}

at getUnits function, I want to get the Window object (win) and call the
getAffectedParts() function.

am I doing something wrong, or am I misssing something?

how can I able to do that?

Best regards.
