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);
