Hi
I was busy so couldn't write an example for you. I had never used this
library directly but I have read its source when I started learning tapestry
5 months ago and it is a great great help. A lot of my components are just a
modification of these components( at times the same component but
reimplemented to learn).
Here is your example.
The class file.
package com.google.code.tapestryaddons.pages;
import java.util.ArrayList;
import java.util.List;
import org.apache.tapestry5.OptionGroupModel;
import org.apache.tapestry5.OptionModel;
import org.apache.tapestry5.PersistenceConstants;
import org.apache.tapestry5.SelectModel;
import org.apache.tapestry5.annotations.Persist;
import org.apache.tapestry5.annotations.Property;
import org.apache.tapestry5.internal.OptionModelImpl;
import org.apache.tapestry5.util.AbstractSelectModel;
import org.chenillekit.tapestry.core.encoders.MultipleValueEncoder;
import com.google.code.tapestryaddons.MyObject;
public class TestPage {
//Selected list
@Property
@Persist(PersistenceConstants.FLASH)
private List<MyObject> selectedList;
//List to supply data from
@Property
private List<MyObject> myList;
void onActivate(){
//Initialize the selected list
if(selectedList == null){
selectedList = new ArrayList<MyObject>();
}
//Fill dummy data. In your case you have to load data
if(myList == null){
//Dummy Data
myList = new ArrayList<MyObject>();
for(int i = 0; i < 10; ++i){
myList.add(new MyObject(i, "MyObject #" + i));
}
}
}
//Log the result
void onSuccess(){
System.out.println(selectedList);
}
//Encoder
public MultipleValueEncoder<MyObject> getEncoder(){
return new MultipleValueEncoder<MyObject>(){
public String toClient(MyObject object) {
return object.getId().toString();
}
public List<MyObject> toValue(String[] values) {
List<MyObject> objects = new ArrayList<MyObject>();
for(String value: values){
for(MyObject myObject: myList)
if(myObject.getId().equals(Integer.parseInt(value))){
objects.add(myObject);
}
}
return objects;
}
};
}
//Model
public SelectModel getModel(){
return new AbstractSelectModel(){
public List<OptionGroupModel> getOptionGroups() {
return null;
}
public List<OptionModel> getOptions() {
final List<OptionModel> options = new ArrayList<OptionModel>();
for(final MyObject myObject: myList){
options.add(new OptionModelImpl(myObject.getName(),
myObject));
}
return options;
}
};
}
}
The template is
<html xmlns:t='http://tapestry.apache.org/schema/tapestry_5_1_0.xsd'>
<body>
<t:form>
<t:ck.MultipleSelect value='selectedList' model='model'
encoder='encoder'/>
<input type='submit' value='submit'/>
</t:form>
</body>
</html>
and finally MyObject is a simple pojo
package com.google.code.tapestryaddons;
public class MyObject {
private Integer id;
private String name;
public MyObject(Integer id, String name){
this.id = id;
this.setName(name);
}
public Integer getId(){
return id;
}
public void setId(Integer id){
this.id = id;
}
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
@Override
public int hashCode(){
return id.hashCode();
}
@Override
public boolean equals(Object o){
if(o == null || !(o instanceof MyObject)){
return false;
}
MyObject myObject = (MyObject)o;
return id.equals(myObject.getId());
}
@Override
public String toString(){
return name + "(" + id + ")";
}
}
Hope it helps
regards
Taha
