Open 1 packages of crescent rolls. Dust a clean surface with a little flour unless you have a very good non-stick surface. Roll out the crescent dough large enough to cover the base and go half-way up the sides of a 13x9 glass pyrex dish. Use any scraps of dough to patch the dough after it's in the pyrex dish.
On medium speed, beat together the cream cheese, sugar, vanilla and egg in a medium bowl, just until it is creamy and smooth.
Spread cream cheese mixture evenly over the crescent in the pyrex dish.
Spread cherry filling evenly over the cream cheese mixture.
Roll the second package of crescent dough to about the size of the pyrex dish top. Cut strips of dough about 1/2" wide.
Place the strips of dough on the cheesecake the long way. Place 1 strip of dough on each edge of the pyrex and push the edges against the glass to seal the edges of the cheesecake.
After all the long strips are on, cut the next set of strips in half and place them the opposite way over the cheesecake to form a lattice. Seal the edges to the pyrex dish and Bbake for 30-35 minute bake until the top is golden brown.
