Description Luigi Pertoldi 2021-09-09 16:13:40 CEST 
G4GenericMessenger::SetRange does not work as expected on a Command created with G4GenericMessenger::DeclareMethod with a function that accepts a numeric type. This happens because DeclareMethod seems to always assign type "string" to the function argument.

The bug can be reproduced by modifying example basic/B5:

1) In B5DetectorConstruction::DefineCommands, create armAngleCmd by invoking DeclareMethod instead of DeclareMethodWithUnit (remove the "deg" unit specification).

2) Substitute "/B5/detector/armAngle 30. deg" with "/B5/detector/armAngle 30." in provided macro run1.mac.

3) Compile the example and run the program. Output:

parameter out of range: angle>=0. && angle<180.
***** Illegal parameter (99) </B5/detector/armAngle 0. deg> *****

***** Batch is interrupted!! *****
