add(new CheckBox("openLocationPanelLink") {
oncomponenttag(tag) {
tag.put("onclick", "var panel=document.getElementById('" +
addLocationPanel.getMarkupId() +
"');panel.style.display=this.checked?'block':'none';")));
}
that way your code will execute during render time at which markupid
is available.
