Jeroen Kransen commented on WICKET-3030:
----------------------------------------
Just ran it with Jetty, and now I get the stack trace too. Apparently Tomcat
(and Glassfish) swallows the info instead of showing it.

> When I use a org.apache.wicket.markup.html.form.ListMultipleChoice in a
> Panel, it shows up ok on the screen. When I submit the form, I get a
> java.lang.IllegalStateException. Full stack trace:
> SEVERE: Servlet.service() for servlet default threw exception
> java.lang.IllegalStateException

> The code that triggers the Exception (does not occur without) is this:
> Java:
> public class FilterPanel extends Panel {
> public FilterPanel(String id, List<String> choices) {
> super(id);
> ListMultipleChoice<String> photographerChoice = new
> ListMultipleChoice<String>("filter.choices", choices).setMaxRows(5);
> add(photographerChoice);
> }
> }
> HTML:
> <wicket:panel>
> <div>
> <select wicket:id="filter.choices">
> <option>choice0</option>
> <option>choice1</option>
> </select>
> </div>
> </wicket:panel>
> There is no more logging besides this, and no more "caused by" Exceptions.
> Good luck! I'll be happy to supply more info.
