Try to use the RemoveLink that is available as inner class of ListView.

Hi!!
Im trying to implement a dynamic Form, where you can add textfields and
remove as you want. The add button works fine, but the remove button always
remove the last testfield and not the selected field. For example:
Textfield1 add remove
Textfield2 add remove
Textfield3 add remove
click on remove (row textfield2) and Textfield3 is removed. It should remove
Textfield2, doesnt it?
Some code:
public class KeywordObject implements Serializable {
private static final long serialVersionUID = 1L;
private String keyword;
public void setKeyword(String keyword) {
this.keyword = keyword;
}
public String getKeyword() {
return this.keyword;
}
}
And in the form...
List<KeywordObject> keyList = new ArrayList<KeywordObject>();
keyList.add(new KeywordObject());
final ListView keywordView = new ListView("keywordView", keyList) {
@Override
protected void populateItem(final ListItem item) {
KeywordObject model = (KeywordObject)
item.getModelObject();
item.add(new TextField("keyword", new
PropertyModel(model, "keyword")));
// keyword add link
Link addKeyword = new Link("addKeyword",
item.getModel()) {
@Override
public void onClick() {
keyList.add(new KeywordObject());
}
};
// keyword remove link
Link removeKeyword = new Link("removeKeyword",
item.getModel()) {
@Override
public void onClick() {
KeywordObject selected = (KeywordObject)
getModelObject();
keyList.remove(selected);
}
};
item.add(addKeyword);
item.add(removeKeyword);
}
};
add(keywordView);
keywordView.setReuseItems(true);
Im getting crazy about that...
Thanks.
