Here is the source code without tabs:
/* advanced search link */
add(new AjaxSubmitLink("advancedSearch") {
private static final long serialVersionUID = 3847759110695405700L;
@Override
protected void onSubmit(AjaxRequestTarget target, Form<?> form) {
advancedSearch = !advancedSearch;
target.addComponent(findUserAcountForm);
}
}.add(new NonCachingImage("expandCollapse", new Model<String>() {
private static final long serialVersionUID = 3430522655787763141L;
@Override
public String getObject() {
return advancedSearch ? "/img/collapse.gif" : "/img/expand.gif";
}
})));
I hope it's more readable this way :-)
