I'm using the function: viewer->getDatabasePager()->getFileRequestListSize() to determine whether background processing of PagedLOD objects is complete. e.g I wait until it returns zero before performing screen grab. This normally works fine, but if there are any files referred to by the PagedLOD nodes are missing, then the files seem to keep getting added back to the database pager file request list by the cull visitor. This means (a) It is continuallly retrying to find each missing file, and (b) the file request queue is never empty and so I can't determine when the loading is as complete as it can get.
My questions are: 1. Should this be happening? 2. How do I avoid it? I suppose I could check for file existence before constructing the PagedLOD object, but I wanted to avoid that because this check is relatively expensive over http, and would prefer that to be deferred to the db pager thread.
