Hi,

Is there a way to reference a type that hasn't been annotated with the [<JavaScript>] attribute?

The reason for asking is because I have types/data setup in a library I'm using within a WPF project. I'm happy to create a WebSharper library and reference those files using Shared Links but I'd like to keep the original code unmodified.

Here's an example:

1
2
3
4
5
6
7
8

type TestData() =
  member x.FirstName with get() = "A"
  member x.Surname with get() = "B"

[<JavaScript>]
type Data() =
  let name = TestData().FirstName
  member  x.People with get() =  [ name ]

Unfortunately this fails the WebSharper compilation with the error:

1

error WebSharper: Failed to translate property access: FirstName [Library1.TestData]

If I annotate TestData with [<JavaScript>] or [<ReflectedDefinition>] then it compiles fine.

I know I can write an translation layer between the two but that's a bit more work than I was hoping for.

I've read that there is a [<Require>] attribute which seems exactly what I want which you use as follows:

1
2
3
4
5

[<JavaScript>]
[<Require(typeof<TestData>)>]
type Data() =
  let name = TestData().FirstName
  member  x.People with get() =  [ name ]

But I'm still getting the same error message.

Is there a way to achieve this or am I stuck with the choice of either modifying my existing code to annotate all the types or writing translations between the two?
