in your case however what you want to accomplish is more appropriate via an ajax call decorator imho.

Here's an interesting case. For an example I'm writing for WIA, I want
to combine an AjaxLink with an attribute modifier. My naive approach
was this:
final AjaxLink removeLink = new AjaxLink(item,
"remove") {
@Override
public void onClick(AjaxRequestTarget target) {
DataBase.getInstance().remove(discount);
discounts = DataBase.getInstance()
.listDiscounts();
DiscountsListView.this.setList(discounts);
DiscountsListView.this.removeAll ();
target.addComponent(tableBody);
}
};
removeLink.add(new AttributeAppender("onclick",
new Model<String>(
"if(!confirm('remove discount for "
+ discount.getCheese().getName()
+ " ?')) return false;"), ";"));
Of course, that doesn't work, as the Ajax link adds a behavior that
simply overrides anything any attribute modifier might have done
/**
* @see wicket.behavior.AbstractAjaxBehavior#onComponentTag(wicket.markup.ComponentTag)
*/
@Override
protected void onComponentTag(final ComponentTag tag)
{
super.onComponentTag(tag);
tag.put(event.getEvent(), getEventHandler());
}
The question now is, what would be an elegant way to let users combine
ajax behaviors and attribute modifiers. I'm not sure what would be
best. If the above code would be:
/**
* @see wicket.behavior.AbstractAjaxBehavior#onComponentTag(wicket.markup.ComponentTag)
*/
@Override
protected void onComponentTag(final ComponentTag tag)
{
tag.put(event.getEvent(), getEventHandler());
super.onComponentTag(tag);
}
I think I would be fine (not tested yet), but I'm not sure if such
implicitness is the best way to go.
WDYT?
