Subject: That type of URL will not work for a Notes url
A workaround would be to have a frameset with two frames. One frame would hold a page that has an action. This action will get the published property, 27311.00 in this case, and then open the document in the other frame. The frame with the page would be hidden so it is never seen (just resize it in Domino Designer.)
I am not sure if there is anything in the composite app library on openntf to help in this case.
Per my post, you have to use the composite application editor to publish the property that has your desired lookup number. Then wire that property to the action that you create on the page that is in the hidden frame of the frameset. That LotusScript action does the work of getting the Notes document that corresponds to the lookup number and then opens the document in the other frame of the frameset.

This works fine as long all the way down to the document level - as you aren’t running Notes 8.x eclipse - one of the many reasons I run Basic - if I have to run 8.x
