Using AJAX to change style of component

[Ryan O'Hara]

I'm fairly new to Wicket and was wondering if there is a way to use  
AJAX to change the style of a WebMarkupContainer?  Below is a snippet  
of my code:

        IModel sourceModel = new Model() {
            public Object getObject() {
                return sourceOptions;
            }
        };
        final DropDownChoice source = new DropDownChoice("source",  
new PropertyModel(this, "sourceSelection"), sourceModel);
        source.add(new AjaxFormComponentUpdatingBehavior("onchange") {
            protected void onUpdate(AjaxRequestTarget target) {
                variationMetricRow.add(new AttributeModifier 
("style", true, new Model(sourceSelection.equals("CHOP_Normals") ?  
"display:block" : "display:none")));
                variationMetricRow.setOutputMarkupId(true);
                target.addComponent(variationMetricRow);
            }
        });
In this example,  I would like to change the display to show/hide a  
particular component.  Any help would be appreciated.

Thanks,
Ryan
