I did this by subclassing RepeatingView and overriding
AbstractRepeater.renderChild as follows...
public class SeparatorRepeatingView extends RepeatingView {
private boolean firstChildRendered = false;
private String separator = " | ";
public SeparatorRepeatingView(String id, IModel model) {
super(id, model);
}
public SeparatorRepeatingView(String id) {
super(id);
}
@Override
protected void onBeforeRender() {
firstChildRendered = false;
super.onBeforeRender();
}
@Override
protected void renderChild(Component child) {
boolean childVisible = child.isVisible();
if (firstChildRendered && childVisible && separator != null) {
getResponse().write(separator);
}
super.renderChild(child);
if (childVisible) {
firstChildRendered = true;
}
}
public String getSeparator() {
return separator;
}
public void setSeparator(String separator) {
this.separator = separator;
}
}
Unfortunately, ListView marks renderChild as final, so this technique
won't work there.
