getClassTypeId problem...

[Jarek Rzepecki <jarekr@xxxxxxxx>]

Hi!
  I have a problem with getClassTypeId. Below is a piece of code. It
compiles well but it doesn't work well...

void create_trace(SoSeparator* OIVparent){
  SoNode* tmp_sep;
  int num_child = OIVparent->getNumChildren();
  for (int i = 0; i<num_child; i++){
    tmp_sep = OIVparent->getChild(i);
    if (tmp_sep->getClassTypeId() == SoCube::getClassTypeId()){
        //do something...
    }
  }
}
num_child is ok, but the tmp_sep = OIVparent->getChild(i) act strange (i
think...) looking in debug tmp_sep is always "incomplate type" , what is
more the compareation in "if" line is always false.
What am i doeing wrong?
In general i would like to extract information about all children (are
thay separator, shape , transformation etc...) i need it to build another
geometry tree.
Thank you.
