For some of my tasks I have a custom data field "tracid" set. In AppleScript I need to find the task where the tracid is set to a particular value.

Currently I am just iterating over the list of tasks until I find the one I want. Is there any faster way to do this?

-- Finds a Task
--   _id : tracid of task
on findTask(_id)
	tell application "OmniPlan"
		tell first document
			
			repeat with t in tasks
				set customData to get custom data of t
				if customData is not {} then
					if (tracid of customData = _id) then
						return t
					end if
				end if
			end repeat
			
			return false
			
		end tell
	end tell
end findTask

-- Finds a Task
--   _id : tracid of task
on findTask(_id)
	tell application "OmniPlan"
		tell first document
			set t to first task whose value of custom data entry "tracid" is _id
			if exists t then
				return t
			else
				return false
			end if
		end tell
	end tell
end findTask

Thanks for the help Lizard.

I tried your code and it causes an error when the task is not found instead of returning false.

I think this is the ticket:

-- Finds a Task
--   _id : tracid of task
on findTask(_id)
	tell application "OmniPlan"
		tell first document
			try
				set t to first task whose value of custom data entry "tracid" is _id
			on error errmesg number errn
				if errn is -1719 then
					return false
				else
					error errmesg number errn
				end if
			end try
			return t
		end tell
	end tell
end findTask
