Yes - don't use a simple attribute modifier. Use an
"AttributeModifier" that takes a model. Return the URL in the model.
pseudo code:
container.add(new AttributeModifier("value", true, new
AbstractReadOnlyModel<CharSequence>()) {
public CharSequence getObject() {
return getRequestCycle().urlFor(dlink, ILinkListener.INTERFACE));
}
});
You're trying to get the URL before the page is constructed / added to
page map - as the error mentions. This delays the URL retrieval until
render time.
