Thanks! That got me in the right direction-- I basically copied
IndicatingAjaxLink and made a IndicatingDropDownChoice below... seems
like it would be good to have as part of the default widget set...
public class IndicatingDropDownChoice<T> extends DropDownChoice<T>
implements IAjaxIndicatorAware {
private final AjaxIndicatorAppender indicatorAppender = new
AjaxIndicatorAppender();
public IndicatingDropDownChoice(final String id) {
super(id);
add(indicatorAppender);
}
/**
* @see
org.apache.wicket.markup.html.form.AbstractChoice#AbstractChoice(String,
java.util.List)
*/
public IndicatingDropDownChoice(final String id, final List<?
extends T> choices)
{
super(id, choices);
add(indicatorAppender);
}
/**
* @see
org.apache.wicket.ajax.IAjaxIndicatorAware#getAjaxIndicatorMarkupId()
*/
public String getAjaxIndicatorMarkupId()
{
return indicatorAppender.getMarkupId();
}
}

Hi,
I have a DropDownChoice that triggers an ajax event to occur using the
AjaxFormComponentUpdatingBehavior. Since the event takes a little while to
complete, I'd like to display an ajaxindicator similar to an
IndicatingAjaxButton next to it... how can this be done?
Have a look at this code, line #137 and #159
http://code.google.com/p/perfbench/source/browse/trunk/perfbench/wicket-jpa/src/main/java/wicketjpa/wicket/MainPage.java#137
In the HTML, use something like:
<img id="spinner" src="img/spinner.gif" style="display:none"/>
You can also use an Image component and get the markupId generated by wicket
instead of hardcoding "spinner" etc. Hope this helps.

Thanks, Jason
