I've traced the values in copy_to_pui, they are ok, and bad in the
format callback.
If I understand well the code, the live values are updated when the gui
subsystem is called (NewGUI::update()).
Those values are stored in char *pointer (before the format call back),
the problem as I see it is that those pointer won't be valid if the data
they point to is updated. And I thing that's what is happening.
The subsystem manager calls NewGui::update and then calls
FGRouteMgr::update. The set_string method
does a delete followed by a new so it's possible that the pointers are
not the same.
As a quick hack I changed the declaration of the route mgr subsystem
(int fg_init.cxx) to
globals->add_subsystem( "route-manager", new FGRouteMgr,
SGSubsystemMgr::INIT );
putting it in the same group as the gui and before it. This seems to work.
Harald.
