hi andi,

to my knowledge... when we make a macro component (it can be made by zul, zs script or compiled java class), it will then act as a new component.
to my knowledge, the macro component based on zul (xml file) offer a quick result but less flexy due to the xml cant have any logical procedures. to do so, each zul file has to have a script file (zs) or we can include that script to the zul file.

as for me.. after months playing zk, i choose to use the compiled java instead.

as for passing the parameters, zk does not communicate via url.. instead, it use the component's id (in zul case) or the component it self (java approach).

for more specific cases... pls submit part of your sample in the forum so we can learn each other..

good luck.. selamat mempergunakan zk :)

Hi Andy,

1)You can use the following example to pass your parameter between zul files.

<zscript>
Executions.getCurrent().setAttribute("key1", "val1"); Executions.getCurrent().forward("/other.zul");
</zscript>

2)Try the following example,

<toolbarbutton id="${each.itemno}" label="${each.itemno}" forEach="${item}"
style="font:30px/1.2em Arial, Verdana, sans-serif;" onClick="myMethod(self)"/>

In Java code,

public void myMethod(Toolbarbutton btn){
System.out.println(btn.getId());
}

Hi Andy,

The Executions.getCurrent().setAttribute() is the same with request.setAttribute(), so you can use the Executions.getCurrent().getAttribute() or request.getAttribute().

hai Chen,

zul file

<?init class="ibs.mainapp" arg0="key1" ?> <label value="${key1}"/>

i am sorry i try create a java code like this

public class mainapp implements Initiator,Controller{

public void doInit(Page page,Object[] args){
String key1 = request.getAttribute();
}

public void doAfterCompose(Page page) throws Exception{}

public void doCatch(Throwable throwable){}

public void doFinally(){}

}

the problem is request method can not be resolved. Could you give me another an example ?



TIA,

andy susanto

hi andy,

i'm not sure if i'm i'm right but u r using implements instead of extends for your class. to my knowledge, implements is used for interfaces while extends is for class (again i may be wrong).
in my macro components (java class) ... i always extends the basic class and i got no problem what so ever w/ the methods, properties etc...


good luck

Hi Andy,

You mistook my meaning.
Try this,

In other1.zul file,

<zscript>
Executions.getCurrent().setAttribute("key1", "val1"); Executions.getCurrent().forward("/other2.zul");
</zscript>

In other2.zul file,
<zscript>
Executions.getCurrent().getAttribute("key");
</zscript>

Please take a look at the API -
http://www.zkoss.org/javadoc/2.4.1/zk/org/zkoss/zk/ui/Execution.html#getAttribut
e(java.lang.String)

Hai Chen,

i read a javadoc but i cannot find about how to pass a variable between zul file.

this is my a zul and java file that will call another zul file when toolbarbutton click

first.zul
<?init class="ibs.transaksi.spa.locker.Locker" arg0="locker" ?> <toolbarbutton id="${each.lockerNo}" onClick="new ibs.transaksi.spa.locker.Locker().test(self)"
label="${each.lockerNo}" forEach="${locker}"
style="font:30px/1.2em Arial, Verdana, sans-serif;"/>


package ibs.transaksi.spa.locker;

import html.tag.NewLine;

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.LinkedList;

import org.zkoss.zk.ui.Executions;
import org.zkoss.zk.ui.Page;
import org.zkoss.zk.ui.util.Initiator;
import org.zkoss.zul.Toolbarbutton;

import database.AutoReconnect;

public class Locker extends LockerObj implements Initiator{

public void doInit(Page page,Object[] args){
List tabLabel = new LinkedList();

Connection Con = null;
PreparedStatement pstmtListTransLocker = null;
try{
Con = AutoReconnect.getConection();

StringBuffer sbSQLStatement = new StringBuffer("SELECT LOCKER_NO,LOCKER_ID ");
sbSQLStatement.append("FROM LOCKER ");
sbSQLStatement.append("WHERE LOCKER_TYPE = 'M' AND LOCKER_SUSPEND=0 ");
sbSQLStatement.append("ORDER BY LOCKER_NO ");

pstmtListTransLocker = Con.prepareStatement(sbSQLStatement.toString());
ResultSet rs = pstmtListTransLocker.executeQuery();

while (rs.next()){
tabLabel.add(new
LockerObj(rs.getString("LOCKER_ID"),rs.getString("LOCKER_NO")));
}


}
catch(SQLException error){
System.err.print("Open Connection Gagal ".concat(error.getMessage()).concat(NewLine.CodeBreak()));
}finally{
page.setVariable((String) args[0], tabLabel);

//Close Connection
if (Con != null){
try{
Con.close();
Con = null;
}
catch(SQLException error){
System.err.print("Close Connection Gagal ".concat(error.getMessage()).concat(NewLine.CodeBreak()));
}
}
}


}

public void doCatch(Throwable ex){

}

public void doFinally(){

}

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

}

public void test(Toolbarbutton a){
StringBuffer sbUrl= new StringBuffer("/forms/display/test.zul");
Executions.getCurrent().setAttribute("key", a.getId());
Executions.sendRedirect(sbUrl.toString());
}
}


second.zul( this file show an attribute which user click from first.zul) <?init class="ibs.mainapp" arg0="rt" ?> <label value="${rt}"/>

public void doInit(Page page,Object[] args){
String test = page.getAttributes().toString();
System.out.println(page.getVariable("key"));

page.setVariable((String) args[0], test);
}

public void doAfterCompose(Page page) throws Exception{}

public void doCatch(Throwable throwable){}

public void doFinally(){}

public ModelAndView handleRequest(HttpServletRequest req, HttpServletResponse

throws ServletException,IOException{
