Multiple TextField in ListView

["Mathias P.W Nilsson" <ma...@snyltarna.se>]

Hi!

In my application a user should be able to connect keywords to a datasheet.

When clicking the link add keywords 10-20 textfields should appear and the
user can enter data to
the fields. 

#1
textField 
#2
textfield
......


How can I handle this like an array in wicket? I do not want to add 20
textfields by hand.

Here is how I would do it:

HTML:
<table>
	<tr wicket:id="tableRow">
		<td>
			. <input wicket:id="textInput" type="text" />
		</td>
	</tr>
</table>


Model Object:
// this is a simple object I am going to use for my model.
// It holds the value the user will enter in the textbox and
// a primary key value, so I know how to update my database 
// when I save.
private class RandomObject implements Serializable{
	private static final long serialVersionUID = 1L;
	private String textValue;
	private int pkValue;
	
	public String getTextValue() {
		return textValue;
	}

	public void setTextValue(String textValue) {
		this.textValue = textValue;
	}

	public int getPkValue() {
		return pkValue;
	}

	public void setPkValue(int pkValue) {
		this.pkValue = pkValue;
	}

	private RandomObject(String textValue, int pkValue){
		this.textValue = textValue;
		this.pkValue = pkValue;
	}

}


Java for the page layout:
// Create objects however...here I make 3
// Store the list somewhere so you can loop through it and save each 
// key word on submit...I did not add the submit code here, but it is basic
enough
ArrayList<RandomObject> myArray = new ArrayList<RandomObject>();
myArray.add(new RandomObject(null, 1));
myArray.add(new RandomObject(null, 2));
myArray.add(new RandomObject(null, 3));

ListView theView = new ListView("tableRow", myArray){
	private static final long serialVersionUID = 1L;

	public void populateItem(final ListItem listItem){
		final RandomObject item = (RandomObject)listItem.getModelObject();
		listItem.add(new Label("numberLabel", new
Model(String.valueOf(listItem.getIndex() + 1))));
                // Could add validation here if needed.
		listItem.add(new TextField("textInput", new PropertyModel(item,
"textValue")));
    }
};

add(theView);

A listview with a listview or a repeater?
