When the program runs, an IScriptControl control generates this:
$create(Nucleo.Web.ListControls.ClientCheckboxListBehavior, {"activeIndex":-1,"selectedIndex":-1}, {"allItemsSelected":ClientCheckboxListTest_AllItemsSelected,"noItemsSelected":ClientCheckboxListTest_NoItemsSelected}, null, $get("ctl00_ContentPlaceHolder1_ClientCheckboxListTest1_extItems"));
However, it's telling me that Nucleo is undefined. I register the namespace in the associated script, and register the class at the end. So I don't understand why it is giving me this error?
Thanks.
