I am using exactly the same functionality to display gpolylines or gmarkers and the 'a is null' error never occurs. Surely, when the error happens, the code stops at the point of pipa.enableEditing() method. If you want to check the gpolylines try, username:richard, password:tipper this works just fine. Also, the functionality to place the polys is almost the same as the one google uses in its example codes for placing and editing gpolys.
