This is my first time to use wicket. Hence, I don't know whether I did it
right or wrong. Anyway, I have reproduced my case below, the first part is
java code, and the second part is markup file. Any idea is appreciated,
Thanks a lot!!
import java.io.Serializable;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

import wicket.markup.html.list.ListItem;
import wicket.markup.html.list.ListView;
import wicket.model.CompoundPropertyModel;
import wicket.model.PropertyModel;
public class TestPage extends WebPage {
private static final List<String> DROP_DOWN_LIST = Arrays
.asList(new String[] { "Sunday", "Monday" });
public TestPage() {
super.add(new TestForm("form"));
}
private class TestForm extends Form {
public TestForm(String id) {
super(id);
List<InnerModel> innerModel = new
ArrayList<InnerModel>();
for (int i = 0; i < 5; i++) {
innerModel.add(new InnerModel());
}
TestModel testModel = new TestModel();
testModel.setInnerModels(innerModel);
super.setModel(new CompoundPropertyModel(testModel));
ListView lv = new ListView("innerModels") {
protected void populateItem(ListItem item) {
CheckBox checkBox = new
CheckBox("checked",
new
PropertyModel(item.getModel(), "checked"));
item.add(checkBox);
DropDownChoice choice = new
DropDownChoice("choice",
new
PropertyModel(item.getModel(), "choice"),
TestPage.DROP_DOWN_LIST);
item.add(choice);
TestForm.this.add(new
TestValidator(checkBox, choice));
}
};
super.add(lv);
}
}
private class TestValidator extends AbstractFormValidator {
private final FormComponent[] formComponents;
public TestValidator(FormComponent comp1, FormComponent comp2) {
this.formComponents = new FormComponent[] { comp1,
comp2 };
}
public FormComponent[] getDependentFormComponents() {
return this.formComponents;
}
public void validate(Form form) {
if ((Boolean)
this.formComponents[0].getConvertedInput() == true) {
if (!this.formComponents[1].getConvertedInput()
.equals("Sunday")) {
this.formComponents[1].error("ERROR!!");
}
}
}
}
private class TestModel implements Serializable {
private List<InnerModel> innerModels;
public List<InnerModel> getInnerModels() {
return this.innerModels;
}
public void setInnerModels(List<InnerModel> model) {
this.innerModels = model;
}
}
private class InnerModel implements Serializable {
private boolean checked;
private String choice;
public boolean isChecked() {
return checked;
}
public void setChecked(boolean checked) {
this.checked = checked;
}
public String getChoice() {
return choice;
}
public void setChoice(String choice) {
this.choice = choice;
}
}
}
