Hello,
Got another problem i guess in the code snippet of the tutorial......if
they are my silly mistake please do not forget to bash me as i am smart
enough to make nasty mistakes
the code snippet the and error message are as follows:

NOW IF I REPLACE THE typedef with the following statement
CoredNodePtr<Geomtry> box/torus = CoredNodePtr<Geometry>::crate();
CoredNodePtr<Group> root = CoredNodePtr<Group>::crate();
the code compiles and runs fine................
Is that issue worth considering or i did something wrong?
