COBCH1718 Best visible constructor in <type-name> is <member-name> which has invalid parameter <param-num>

In the following example, there is no compatible match for the call to the new constructor using the argument supplied. There is a constructor with the same number of parameters; however, the parameter is not a compatible match. Either change the argument to be compatible with type string, or change the new constructor to accept a type compatible with a numeric.

class-id axel.
method-id main.
  declare obj as type axel
  set obj to new axel(3)
end method.
method-id new (s as string).
...
end method.
end class.
