Help ! CompoundPropertyMode and ArrayList Question
The code bellow：
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import wicket.markup.html.*;
import wicket.markup.html.basic.Label;
import wicket.markup.html.form.Form;
import wicket.markup.html.link.Link;
import wicket.markup.html.list.ListItem;
import wicket.markup.html.list.ListView;
import wicket.markup.html.panel.FeedbackPanel;
import wicket.markup.html.form.*;
import wicket.model.*;
public class TestPage extends WebPage implements Serializable
{
private static final long serialVersionUID = 1L;
private List testList=new ArrayList();
private ListView testListView;
public TestPage()
{
final FeedbackPanel testFeedback = new FeedbackPanel("testFeedback");
add(testFeedback);
WebMarkupContainer dataContainer = new WebMarkupContainer("data");
dataContainer.setOutputMarkupId(true);
this.add(dataContainer);
testListView = new ListView("testList", testList){
private static final long serialVersionUID = 1L;
protected void populateItem(ListItem listItem){
final TestTO to=(TestTO)listItem.getModelObject();
listItem.add(new Label("file", to.getFileInput()));
System.out.println("to.getFileInput(0:"+to.getFileInput());
listItem.add(new Label("notes",to.getFileNotes()));
listItem.add(new Link("delete"){
public void onClick()
{
testList.remove(to);
}
});
}
};
dataContainer.add(testListView);
Form uploadForm = new Form("uploadform",new CompoundPropertyModel(new
TestTO())){
private static final long serialVersionUID = 1L;
protected void onSubmit(){
TestTO to=(TestTO)getModelObject();
System.out.println("****** Input:"+to.getFileInput());
System.out.println("Now size a:"+testList.size());
if(testList.size()>0)
{
System.out.println("First
value:"+((TestTO)testList.get(0)).getFileInput());
}
testList.add(to);
System.out.println("Now Size b:"+testList.size());
}
};
uploadForm.add(new TextArea("fileNotes"));
uploadForm.add(new TextField("fileInput"));
add(uploadForm);
}
private class TestTO implements Serializable{
private static final long serialVersionUID = 1L;
private String fileID;
private String fileNotes;
private String fileInput;
public TestTO(){}
public String getFileID() {
return fileID;
}
public void setFileID(String fileID) {
this.fileID = fileID;
}
public String getFileNotes() {
return fileNotes;
}
public void setFileNotes(String fileNotes) {
this.fileNotes = fileNotes;
}
public String getFileInput() {
return fileInput;
}
public void setFileInput(String fileInput) {
this.fileInput = fileInput;
}
}
}
and the html code：
<?xml version="1.0" encoding="UTF-8"?>
File
Note
File
Notes
Del
(file)
(notes)
img/delete.gif
*******************
when execute the code, the console show:
****** Input:1
Now size a:0
Now Size b:1
to.getFileInput(0:1
****** Input:2
Now size a:1
First value:2
Now Size b:2
to.getFileInput(0:2
to.getFileInput(0:2
I first input 1 and then input 2 ,but the two value all become 2,why? Could
anyone help me to solve this question?

This is the problem. You only add a single TestTO obj to it at constructor
time. It means the page
will keep updating this object and adding the same object to the list. To
fix it quickly, add a
line:
protected void onSubmit() {
TestTO to = (TestTO) getModelObject();
setModelObject(new TestTO());
...
}

Not too lazy, but very time constrained.

John, sorry for not being helpful. But I think that this kind of posts (this
is my code, why it doesn't work?) will not help you to find the problem. My
suggestion is, try to debug your code, and if you have a more specific
question, post it and somebody for sure will give you an answer. Otherwise,
everybody will just overlook your post. The most of developers are too lazy
to find what exactly is not right with your code.
Alex.
