view engine/core/view/renderers/coordinaterenderer.cpp @ 202:1d9154c535cf

fixed bug where the root directory path name was being added to the filename twice. It was initially added in the listFiles/listDirectories functions and then added again in the private function list. I modified the code so it is only added in the list function now.
