value:random

Hi Lukas, when I saw value:random I thought that this was just what I had been wanting. I immediately gave it a try, expecting it to be "a random child of the page in which the link is placed". Well it worked fine until I embedded that page into another page, and then I discovered that it is "random child of the current structure". Not what I expected at all. So I investigated these value links, only to find that these links do not appear to know their document, thus making my original idea impossible to implement with value links. To be honest I have hit this problem many times since I started using pier. I never have any use for "children of the current structure", and there are many "current structure" based features in pier. I always want children of a specific structure. Then I can craft a menu, and embed it somewhere else, or similar. So I implemented a subclass of value links, implementing "page:" links, and it works great. Then I had a thought: the most powerful, and oft forgotten feature of Ward Cunningham's original wiki, was the ability to click on the title of a page, and get all of the referring pages. So how does one get "all of the links that link to this page". btw: the code in the comment to PRIncomingReferences is not a valid example as far as I can see. cheers Keith
