Not Enough Arguments Error

But when it is read as blank from setting into view.mc it behaves like a empty string. It is not null, but it seems to be nothing else but „nothing“.

Ok, but as a programmer you must understand that when you read that blank setting in your Monkey C code, the result has to be *something*, whether it's null or an empty string (""). I realize that when you log an empty string using System.println() it literally prints as nothing, but in reality, there's still a type associated with the data. It's not like javascript where an object can have an optional property that's literally absent (in a manner that's distinct from the property being equal to null.)

If you want to confirm that it's an empty string, you could log the result of x instanceof Lang.String && x.length() == 0  for example. Or even more simply: "".equals(x)

You‘re right with string checking - I could try this.
But I thought - if it is a empty string it should throw an exception if a Numeric is feed with a string.

But anyway - the solution is „required=true“ in settings.

Thanks to all if you!

With type checking, things are only checked at compile time, not run time so even you you cast something as "as Numeric "

at run time you can set it to be any object type.  There is no checking at that time.
