Bei AJAX-Request (vermute ich zumindest) ist der Stacktrace in der aktuellen Version ziemlich nutzlos:
Code
#1 /lib/action/TAJAXException.class.php (68):
wcf\system\exception\ValidateActionException->__construct()
#2 /lib/action/AJAXInvokeAction.class.php (113):
wcf\action\AJAXInvokeAction->throwException()
#3 /lib/action/AbstractAction.class.php (53):
wcf\action\AJAXInvokeAction->execute()
#4 /lib/action/AJAXInvokeAction.class.php (65):
wcf\action\AbstractAction->__run()
#5 /lib/system/request/Request.class.php (89):
wcf\action\AJAXInvokeAction->__run()
#6 /lib/system/request/RequestHandler.class.php (119):
wcf\system\request\Request->execute()
#7 /foo/index.php (10):
wcf\system\request\RequestHandler->handle()
