Hi there,
I'm trying to implement an AJAXfied Wicket list view. On my research I
stumbled upon the code on
http://www.oktech.hu/kb/adding-and-removing-rows-wicket-listview-via-ajax
and modified it a bit.
The model is not updated properly. So whenever a value is entered in a text
field, it is forgotten if the AJAX submit link is invoked (the text field is
empty again). Why does this happen? I don't see any issue with this code.
Wicket version is 1.5.2.
Here is the Java code:
// Initialization of form
...
// List all rows
ArrayList<String> rows = new ArrayList<String>(2);
rows.add(new String());
rows.add(new String());
final ListView<String> lv = new ListView<String>("rows", rows) {
@Override
protected void populateItem(ListItem<String> item) {
int index = item.getIndex() + 1;
item.add(new Label("index", index + "."));
TextField<String> text = new TextField<String>("text",
item.getModel());
item.add(text);
}
};
rowPanel.add(lv);
AjaxSubmitLink addLink = new AjaxSubmitLink("addRow", form) {
@Override
protected void onError(AjaxRequestTarget target, Form<?> form) {
if (target != null) target.add(rowPanel);
}
@Override
protected void onSubmit(AjaxRequestTarget target, Form<?> form) {
lv.getModelObject().add(new String());
if (target != null) target.add(rowPanel);
}
};
addLink.setDefaultFormProcessing(false);
rowPanel.add(addLink);
...
And the associated mark up:
<div wicket:id="rowPanel">
1.
<input type="text" wicket:id="text"/>
# Add row
</div>
Has someone any idea on this issue? I'm completely stuck on this issue.
Thanks in advance.
Best regards,
Sebastian
