Thanks Vincent!!! Change made and everything working ok :-)
I'm trying to open iTop changes from another application. But I only have the id of the change, like 'C-314159'. If I try to compose an URL to open the change in a browser, I need to know the kind of change that the user wants to see (NormalChange, EmergencyChange or RoutineChange), because it needs to be in the URL as the class parameter. Is there any way of opening directly the details of the change knowing only de 'id'?
