It looks like you have an object the is being hidden/shown in there somewhere... The Shadowmapping demo that I posted doesnt require objects to be masked or hidden/shown, just the camera(and objects that you DONT want to cast shadows)
Thats what it looks like from the code you posted, the Jittmermap looks like its being made correctly but I cant tell from what you have posted if the rest would be working correctly or not it looks mostly right except for the hiding of the object...
Here is the full working source code to my shadowmapping demo(using evolved's shader) You can see if you have a look through that the objects in there arent being masked/hidden at all..

If it ain't broke.... DONT FIX IT !!!
