magento - Prototype Cannot call method 'get' of undefined -


the chrome console giving me error:

uncaught typeerror: cannot call method 'get' of undefined

i search line , found this:

  function _createresponder(element, eventname, handler) {     var registry = element.retrieve(element, 'prototype_event_registry');      if (object.isundefined(registry)) {       cache.push(element);       registry = element.retrieve(element, 'prototype_event_registry', $h());     }     var respondersforevent = registry.get(eventname);

uncaught typeerror: cannot call method 'get' of undefined

 if (object.isundefined(respondersforevent)) {       respondersforevent = [];       registry.set(eventname, respondersforevent);     }

this seems happening when "null" element passed function on event binding. try adding following before second line (var registry = ...)

if (element === null) return;

this prevent further processing within function, should not necessary when element null.

i haven't found issue doing on magento, please let me know if there problem using fix.
