use a listview,propertylistview or repeater...
Differences are:
listview: iterates over a list
propertylistviw:-||- and bound the item.model via a compound model, very
usefull if you use compound models a lot.
repeater: repeats for int times, as I remember it..

Hi,
I have designed a panel of form text fields which I would like to repeat in
a panel of form.
Here is the code:
EmptyForm.java
public class EmptyForm extends Form
{
private final ValueMap properties = new ValueMap();
public EmptyForm(final String id)
{
super(id);
}
public void addFormComponent(
FormComponent formComponent)
{
add(formComponent);
}
public ValueMap getValueMap()
{
return properties;
}
public final void onSubmit()
{
// some stuff
}
}
EmptyFormPanel.java
public class EmptyFormPanel extends Panel
{
private EmptyForm emptyForm;
private ValueMap valueMap;
/**
* @see org.apache.wicket.Component#Component(String)
*/
public EmptyFormPanel(final String id)
{
super(id);
emptyForm = new EmptyForm("emptyForm");
valueMap = emptyForm.getValueMap();
add(emptyForm);
List<TextFieldBean> textFields = new ArrayList<TextFieldBean>();
textFields.add(new TextFieldBean("User Name", "userName"));
textFields.add(new TextFieldBean("Password", "password"));
ListView formTextFieldPanels = new ListView(
"formTextFieldPanels" ,
textFields)
{
protected void populateItem(ListItem item)
{
TextFieldBean textFieldBean = (TextFieldBean)
item.getModelObject();
FormTextFieldPanel formTextFieldPanel = new
FormTextFieldPanel("formTextFieldPanels");
//item.add(formTextFieldPanel);
formTextFieldPanel.addItem(emptyForm, item,
textFieldBean, valueMap);
//emptyForm.add(formTextFieldPanel);
}
};
add(formTextFieldPanels);
}
public EmptyForm getEmptyForm()
{
return emptyForm;
}
public ValueMap getValueMap()
{
return valueMap;
}
}
EmptyFormPanel.html
<html xmlns:wicket>
<body>
<wicket:panel wicket:id="emptyFormPanels">
<form wicket:id="emptyForm">
<table>
<div wicket:id="formTextFieldPanels"></div>
<tr>
<td></td>
<td>
<input type="submit" name="submit"
value="Sign In"/>
<input type="reset"
value="Reset"/>
</td>
</tr>
</table>
</form>
</wicket:panel>
</body>
</html>
FormTextFieldPanel.java
public class FormTextFieldPanel extends Panel
{
public FormTextFieldPanel(String id)
{
super(id);
}
public void addItem(
EmptyForm emptyForm,
ListItem item,
TextFieldBean textFieldBean,
ValueMap valueMap)
{
item.add(new Label("fieldNameLabel",
textFieldBean.getFieldName()));
item.add(new TextField("fieldId", new PropertyModel(valueMap,
textFieldBean.getFieldId())));
//emptyForm.add(item);
}
}
FormTextFieldPanel.html
<html xmlns:wicket>
<body>
<wicket:panel id="formTextFieldPanels">
<tr>
<td align="right"
wicket:id="fieldNameLabel">fieldName</td>
<td>
<input wicket:id="fieldId" type="text"
value="[EMAIL PROTECTED]" size="30"/>
</td>
</tr>
</wicket:panel>
</body>
</html>
I would like "FormTextFieldPanel" to repeat inside "EmptyFormPanel"
My problem is with "formTextFieldPanels" component.
If I use
emptyForm.add(formTextFieldPanel);
then I get the error message that "formTextFieldPanels" is being repeated (
" a component by this name already exists")
If I don't use it then I get the error message that this component is
missing.
Can some one please tell me what will be the right way to handle this.
I tried to do search for this and it seems that there is a way of doing this
by using RepeaterView.
If so then please let me know how.
Thank you
