Is there an unnecessary quotation mark after [titleID]?
Try delete it and see if works.
If it still not working, My suggestion is:
(1)you can implement the search logic in the method [viewPage], and
access the search result via a new property.
or
(2)use a Map instead of a List, so you can retrieve the value by the key
or
(3)in your action class, add a new [Object Indexed Property] which
retrieve the value from your list by the titleID
