I am working on a simple visualforce page that creates a task. The issue I am running into is that we have turned on  the Activity Setting "Allow Users to Relate Multiple Contacts to Tasks and Events". So instead of getting the pop up window to select up to 50 contacts I get the standard pick one and your done contact picker. Thoughts?
