Re: [Wicket-user] Update ListView via AJAX
Thanks again Igor that was just the ticket. I've updated the wicket wiki
with an example:

overriding the onAttach() method of WebMarkupContainer to remove the
list and regenerate it from the DB on each rendering:
public class AjaxContainer extends WebMarkupContainer {
protected void onAttach() {
removeAll();
ListView comments = new ListView(comments, commentList) {

Do you forsee any problems with this approach?

I traced it back to the parse method in XmlPullParser, specifically
where the xmlReader is closed in the finally block:
finally

I think this exception can be avoided by changing:
this.xmlReader.close ();

if (this.xmlReader != null) this.xmlReader.close();
However, what is causing the xmlReader object to be null?
Is there a way to redirect these errors to a log file instead of
