The exact error (javascript) is TypeError: $(...) is null
As per the Widget documents i need to invoke below to activate the multiselect. $(document).ready(function(){ $("#myselect").multiselect(); }); So it can not find #myselect in this case, i put a alert on this and it prints null, but it does work on another simple wicket panel. Looks like some sort of conflicts happening here. I also tried jQuery.noConflict() but it did not help. Also tried to add a markupid to my select and used that id to call the function but that too did not work, not sure why it will not find that select component. Even an alert on document.form.component prints null, when the comp is indeed there. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/How-to-avoid-this-error-TypeError-is-null-tp4655409p4655429.html Sent from the Users forum mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
