(and if you don't want to disturb the state of your view, and folder-tracking seems to be a regular issue, then you can always reach for the universal duct tape, and install a simple applescript button on your toolbar - sth like this):
Code:
property pTitle : "Show folder path"
property pVer : "0.02"
tell application id "OFOC"
tell front document window of front document
repeat with oPanel in {content, sidebar}
set lstValue to value of (selected trees of oPanel where class of its value is project or class of its value is task)
if length of lstValue > 0 then exit repeat
end repeat
if length of lstValue < 1 then return
display dialog my FolderPath(first item of lstValue) buttons {"OK"} default button "OK" with title pTitle & " ver. " & pVer
end tell
end tell
on FolderPath(oNode)
set str to ""
tell application id "OFOC"
set oParent to container of (containing project of oNode)
repeat while class of oParent = folder
set str to name of oParent & ":" & str
set oParent to container of oParent
end repeat
end tell
return str
end FolderPath
