In community/applications/addons/controllers/class.getcontroller.php, line 19: replace $this->AddJsFile('js/library/jquery.js'); with $this->AddJsFile('jquery.js'); ?

Cant display the Events in Sidepanel: "Fatal error: Call to undefined function PanelHeading() from DiscussionEvent/views/modules/discussionevent.php on line 19" And it woud be great when the Checkbox of "Is this an Event?" isn't checked by default.
