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.
Regards
Julien Roche
