Message "l'activité parente doit appartenir au même projet" - by: bgonzalez

Hello,

When i try to copy a model of a project to create my own real project, i can't get the copy. I obtain this message "l'activité parente doit appartenir au même projet" (= the parent activity must belong to same project") ; what's the problem ? must the model be a parent of the new real project ? or is it that i don't have the right to do the copy ?

I have created the model by myself;

Thanks;
