Re: ListView + dynamic rows: always remove last row...
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...
ListKeywordObject keyList = new ArrayListKeywordObject();
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.

Just as a test, turn off the reuseItems property. See what happens.

Re: ListView + dynamic rows: always remove last row...
Also, is the item you're trying to remove a null in the list? Or, is it a problem with equals/hashcode not being implemented correctly? I just fixed a bug in ListView this week with the remove link and move up/down links. It was relying on the equals of the model object of the item to find which to remove. Now it removes by index. But I think James is on to the right answer for your case. On Sat, Jun 19, 2010 at 7:50 AM, James Carman ja...@carmanconsulting.comwrote: Just as a test, turn off the reuseItems property.

Re: ListView + dynamic rows: always remove last row...
Hi, I tried with/without setReuseItems and the behaviour is the same. I think you can be right with equals/hashcode not being implemented correctly... I tried another time with a ListString with different values and its working... I tried as well to implement these methods (equals/hashcode) in my code but it doesnt work. How can I differentiate objects even if when they are added (they are textfields) they just have empty values Thanks for the help! -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/ListView-dynamic-rows-always-remove-last-row-tp2260480p2261292.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: ListView + dynamic rows: always remove last row...
What kind of objects are they? For entities, I use a uuid for the primary key and it's assigned when the object is created. That way you make equals/hashcode based on the uuid so that everything stays consistent On Jun 19, 2010 1:42 PM, jOki joa...@gmail.com wrote: Hi, I tried with/without setReuseItems and the behaviour is the same.

ListView + dynamic rows: always remove last row...
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?

public class KeywordObject implements Serializable {
private static final long serialVersionUID = 1L;
private String keyword;
public void setKeyword(String keyword) {

}
public String getKeyword() {
return this.keyword;
}
}
And in the form...
ListKeywordObject keyList = new ArrayListKeywordObject();
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.
