I have multi persons pojo with multi addresses. Is there a way to list all persons and their corresponding addresses, or return the first element of the array of the addresses? Is my controller, I would have:
public class EditAttorneyController extends GenericForwardComposer {
List<Person> persons;
@Override
public void doAfterCompose(Component comp) throws Exception {
super.doAfterCompose(comp);
comp.setAttribute("controller", this);
//populate persons
persons = DAO.getAllPersons();
}
}
My zul:
<listbox id="personsLb" multiple="false" model="@{controller.persons}">
<listitem self="@{each='person'}">
<listcell><label="@{person.name}"/></listcell>
<listcell><label="@{person.addresses[0].street1}"/></listcell>
</listitem>
</listbox>
ZK does not return the first element [0] of the array but returns the whole array. Is there a way to pick off the first element or have another self="@{each='addresses'}" nested inside the listbox?
Hi xnguyen
The collection only can set to the model when using databinding
please refer to here
You can use TypeConverter
Composer.java
package ctrl;
import java.util.*;
import org.zkoss.zk.ui.Component;
import org.zkoss.zk.ui.util.GenericForwardComposer;
public class Composer extends GenericForwardComposer {
List<Person> persons;
@Override
public void doAfterCompose(Component comp) throws Exception {
super.doAfterCompose(comp);
initData();
}
private void initData() {
persons = new ArrayList<Person>();
persons.add(new Person("Jimmy", new String[]{"Wisconsin","San Francisco"}));
persons.add(new Person("Katrina", new String[]{"New York","Las Vegas"}));
}
public List<Person> getPersons(){
return persons;
}
public class Person{
private String name;
private String[] addresses;
public Person(String name, String[] addresses) {
super();
this.name = name;
this.addresses = addresses;
}
public String getName() {
return name;
}
public String[] getAddresses() {
return addresses;
}
}
}
MyConverter.java
package view;
import org.zkoss.zk.ui.Component;
import org.zkoss.zkplus.databind.TypeConverter;
public class MyConverter implements TypeConverter {
@Override
public Object coerceToBean(Object val, Component comp) {
return null;
}
@Override
public Object coerceToUi(Object val, Component comp) {
String[] addresses = (String[]) val;
return addresses[0];
}
}
index.zul
<?page title="new page title" contentType="text/html;charset=UTF-8"?>
<?init class="org.zkoss.zkplus.databind.AnnotateDataBinderInit"?>
<zk>
<window border="none" id="win"
apply="ctrl.Composer">
<listbox id="personsLb" multiple="false" model="@{win$Composer.persons}">
<listitem self="@{each='person'}" >
<listcell label="@{person.name}"/>
<listcell label="@{person.addresses, converter='view.MyConverter'}" />
</listitem>
</listbox>
</window>
</zk>
My Issue is like the above, but My data source type is " List<Object[]> ".
The Object[] contents are like :
obj[0] = new Project();
obj[1] = new String("project manager name");
......
and my zul file code is simply like:
......
<listbox id="projListbox" model="projList">
<listhead sizable="true">
<listheader label="Project code" />
<listheader label="Project name" />
<listheader label="Project Manager name" />
......
</listhead>
<listitem self="@{each='proj' }">
<listcell label="@{proj[0].code }"/>
<listcell label="@{proj[0].name }"/>
<listcell label="@{proj[1] }"/>
......
</listitem>
</listbox>
......
But seems I can't retrieve the properties of the beans by the data-binding annotation shown above.
So Combining the beans into 1 custom bean used only in UI is the only way I can use ?
Do I have better solutions in this situation?
Thanks, and Sorry about my poor English. ><"
@wiselytwu,
Write TypeConverter that will convert proj to proj[0].code for first column...
public class PrjCodeConverter implements TypeConverter {
@Override
public Object coerceToBean(Object val, Component comp) {
return null;
}
@Override
public Object coerceToUi(Object val, Component comp) {
Object[] proj = (Object[]) val;
return ((Proejct)proj[0]).getCode();
}
}...
<listitem self="@{each='proj'}">
<listcell label="@{proj, converter="view.PrjCodeConverter"}"/>
...
</listitem>Asked: 2010-05-17 19:50:15 +0800
