I added a checkbox to the activity list (Case detail view) that does the same thing as selecting the drop down and then selecting close.
I don't like that not only does it close the task but it reloads the entire case detail view page. I'd rather have it close the task in the background without reloading the page. The task list doesn't have to be updated as the checked checkbox gives indication it was closed in this session.
The onclick call is: SUGAR.util.closeActivityPanel.show
What is the easiest way to keep it from reloading the page after closing the task?
