Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

To simply explain what I've done : I have an experimental setup that contain several identical detectors. These detectors are complex and I cannot use Replica or Parameterized Volume.
To do so I've built a DetectorConstruction class called MyDecConstruction. The experimental setup is built in another DetectorConstruction class called MyExpConstruction.
In MyExpConstruction I declare two detectors like this : MyDecConstruction* Dec1 = new MyDecConstruction(); Dec1->Construct(); MyDecConstruction* Dec2 = new MyDecConstruction(); Dec2->Construct();
When I use (declare) only Dec1, program runs fine and tracking operates within the detector. But when I add Dec2, I obtain this message :

I don't really understand what that error means and how to solve it.
