Hrmm... I suspect that somewhere one of your components is holding on to a
copy of the list, and isn't modified. Have you tried using a model, shared
between the component you want to refresh and the link that will modify the
list? If the link modifies the list, then the component that has the same
model is added to the ajax target, it should know that the underlying list
has changed. I shy away from any constructor that takes a list directly for
this reason - I'd rather have a model, and then use it any place that needs
access to that list.
BTW - With ListView, it would be real easy to make table rows....
add(new ListView<Foo>("list", new PropertyModel(myObject, "myListOfStuff"))
{
populateItem(ListItem<Foo> item) ....
});
HTML:
<table class="foo">
<tr wicket:id="list">
<td><span wicket:id="someLabelYouAddedToListItem"></span></td>
<td><a wicket:id="someLinkYouAddedToListItem">click me</a></td>
</tr>
</table>
