Hi Peter, The "right" way for your case will be:
add(new WiqueryAbstractBehavior() { public JsStatement statement() { return new JsStatement ().$(null, ".check-login").chain("attr", "'href'", "'#'"); } }); In the standard process, we will never have an empty component when the renderHead method is called. Maybe we will renforce the code to enable your approach.
