Oh, if this helps, what I want could be achieved with this:
<span wicket:id="foobar">
<span wicket:id="text">TEXT</span>
<span wicket:id="star">*</span>
</span>
and then doing something like:
foobar = new MarkupContainer("foobar");
foobar.add(new Label("text", ...))
foobar.add(new WebMarkupContainer("removeMe") {
public boolean isVisible() {
return sometimesFalse();
}
});
add(foobar);
but I find the template html to be less readable in this case and was
hoping to not have to do it this way.
