Multiple app modules no longer works

[MariusDrulea]

The example provided here does not seem to work after the most recent updates of genie, genieframework. Tested on an Ubuntu machine with Julia 1.10 and also Julia 1.9.4.
https://learn.genieframework.com/docs/guides/adding-reactive-pages#multiple-app-modules

The code compiles, but the web page does not display anything.

It works if I downgrade to:
Julia 1.9.4
(GeniePlay) pkg> status
[c43c736e] Genie v5.21.2 https://github.com/GenieFramework/Genie.jl.git#v5.21.2
[a59fdf5c] GenieFramework v1.26.4 https://github.com/GenieFramework/GenieFramework.jl.git#v1.26.4

It does not work if I:
Julia 1.10
(GeniePlay) pkg> st
[c43c736e] Genie v5.21.2 https://github.com/GenieFramework/Genie.jl.git#v5.21.2
[a59fdf5c] GenieFramework v1.26.4 https://github.com/GenieFramework/GenieFramework.jl.git#v1.26.4

So it's not just Julia 1.10, also the most recent versions of GenieFramework and Genie are causing this in Julia 1.9.4.

Btw, the usage of Index and Form can be simplified like below, just use Index.ui instead of Main.App.Index.ui.

module App
  using GenieFramework
  @genietools

  include("Index.jl")
  include("Form.jl")


  @page("/", Index.ui, model=Index)
  @page("/form", Form.ui, model=Form)
end

I downgraded Genie to 5.21.2 as suggested by @MariusDrulea and it works on Julia 1.9.3. This is the code I'm testing with

module App

using GenieFramework
@genietools

module Index
using GenieFramework

@app begin
    @out name = "John"
end

function ui()
    h1("Welcome {{name}}!")
end

end

module Form
using GenieFramework
using Statistics

@app begin
    @in N = 0
    @out m = 0.0
    @onchange N begin
        @show N
        m = mean(rand(N))
    end
end

function ui()
    cell([
          textfield("How many numbers?", :N)
          p("The average of {{N}} random numbers is {{m}}")
         ])
end

end

using .Index
using .Form

@page("/", Main.App.Index.ui, model= Main.App.Index)
@page("/form", Main.App.Form.ui, model= Main.App.Form)

end

@MariusDrulea @PGimenez thanks, I'll allocate some time to debug it.

@MariusDrulea @PGimenez this is fixed in Stipple 0.27.30 but will require an extra configuration Stipple.ALWAYS_REGISTER_CHANNELS[] = true

Previous example adapted:

module App

using GenieFramework
@genietools

module Index
using GenieFramework
Stipple.ALWAYS_REGISTER_CHANNELS[] = true

@app begin
    @out name = "John"
end

function ui()
    h1("Welcome {{name}}!")
end

end

module Form
using GenieFramework
using Statistics
Stipple.ALWAYS_REGISTER_CHANNELS[] = true

@app begin
    @in N = 0
    @out m = 0.0
    @onchange N begin
        @show N
        m = mean(rand(N))
    end
end

function ui()
    cell([
          textfield("How many numbers?", :N)
          p("The average of {{N}} random numbers is {{m}}")
         ])
end

end

using .Index
using .Form

@page("/", Main.App.Index.ui, model= Main.App.Index)
@page("/form", Main.App.Form.ui, model= Main.App.Form)

end

I think we can improve on this, ex in the @page macro, if we pass the model explicitly, we should maybe automatically enable Stipple.ALWAYS_REGISTER_CHANNELS[].

Or better understand the difference between explicitly passing models or not... Something behaves differently.
