LDEB-1552LDEV-1548 Fixed PI issue with Optional redraw - focusOut method only updates title/desc fields and therefore doesn't need complete redraw of children.
LDEV-1553 Moved branchView reference to be inside Activity object and not the CanvasActivity movieclip (canvas object). Therefore have resolved the bug when optionals are redraw due to an update (ie adding or removing or moving an activity).
