Optional parameter not recognized

Hi,
maybe I have found a problem with optional parameters.
Consider a class in a Vulcan.NET library with one constructor with two optional parameters, one of the parameter default values is cast:
Code: Select all
CLASS ClassWithCtor
CONSTRUCTOR(name := NULL_STRING AS STRING, number := (INT)1 AS INT)
RETURN
END CLASS
Then code that calls that constructor with one one argument:
Code: Select all
LOCAL test := ClassWithCtor{"fancy"} AS ClassWithCtor
If this line calling the constructor is in a Vulcan.NET library it compiles without errors. If it is in an X# library I get this error:
'InheritedXsharp.ClassWithCtor{ STRING }' : no constructor that accepts these argument types VulcanReferencingXsharp
I have attached a demo solution.

Otto,
Which dialect ? (Default parameters are handled differently in the Core dialect then in VO/Vulcan).

Guys,
I am afraid I can't reproduce the problem. Matthias, do you mean that you get an error when trying to use the X# class from a vulcan library? Or from another X# library? In the solution you provided, I see the class and the code calling it defined in the same .prg file and it compiles ok here.
Can you please give some more info?

Hi Chris,
I placed two calls in the solution. The one you found works here, too. The second one is in the Vulcan-Project "VulcanReferencingXsharp", and this one gives the compiler error.
Do you not get that error when you compile the hole solution?

Vulcan.NET
I'll also try to create an sample. Didn't work the first time...

I do not have vulcan installed in VS, so I could not test this, but tried the same scenario in XIDE and it worked without errors. Maybe it has to do with compiler options, will try to replicate the same and try again.
But in any case, is this scenario important for you, to use a X# dll from a vulcan project?

Hi Chris,
the scenario is important for me because I'm evaluating the transition of a huge Vulcan.NET solution to X#. Since I get some errors from the X# compiler that I can't resolve yet (e. g. calls to CCALLNATIVE) in a base project, my plan was to reset this project back to Vulcan.NET in order to be able to evaluate other projects that depend on the base project.
