thank you Marcus.
for fullness (for future readers) I have pasted the whole ts file below. it contains much that is unlikely to be germane to this issue.
I have given your initialiser format a try (an anonymous function) and it no longer bleats. Thank you. I am unsure why though! (that an anonymous function would work but a named function would not)!
