Cool, that worked.  Thanks, Frank.

You have to set outMarkupId when creating the component. It's too late

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,
