Error with the Application experimental framework

[gogson]

Hi,

I'm trying to upgrade my OPA 0.9.2 project to the 1.1.1 version.

I'm facing an issue when I try to launch my application:

Error: Your toplevel contains value which can't be synchronously computed
    at global.BslCps_topwait (/opt/mlstate/lib/opa/stdlib/opabsl.opp/opabslNodeJsPackage.js:922:7)
    at Object.<anonymous> (/Users/hugolafitte/sandbox/opa/placeloop.exe:4837:21)
    at Module._compile (module.js:456:26)
    at Object.Module._extensions..js (module.js:474:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)
    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)
    at node.js:901:3

After investigating the error, it seems that it occurs with the experimental application framework which is used in my project (this file: https://github.com/MLstate/opalang/blob/master/lib/experimental/framework/application.opa)

One of my former colleague tried to fix this problem but can't achieved it.
(see: http://forum.opalang.org/0_459)

As he said, removing this framework would be very painful for us as it is managing our pages creation and routing.

Should I remove this framework ? Or is there any solution ?
Do I have a simple alternative to this framework ?

Thanks

Hi, can you post (privately if needed) the surrounding of the guilty line
(in placeloop.exe) ? I remember having used this framework with 1.X
versions using a simple fix.

Here's the line in the OPA exec file:

global.___contact = BslCps_topwait(__v1_make({tl:{nil:js_void},hd:"contact"},__v3_bslcps_update_cont(cont(BslCps_topk),{none:js_void},"_v3_make","File \"src/path.opa\", line 6, characters 16-45, (6:16-6:45 | 116-145)",js_void)));

And here's the src/path.opa file:

  Main = {{
    //TODO: clean me up, useless path
    main =     Page.Handler.make([])
    contact =  Page.Handler.make(["contact"])
    login =    Page.Handler.make(["email"])
    easy_register = Page.Handler.make(["register","easy"])
    register = Page.Handler.make_with(["register", ""], Rule.consume, identity, "")
    register_confirmation = Page.Handler.make(["register","confirmation"])
    valid_account = Page.Handler.make_with(["register","validate", ""], Rule.alphanum_string, identity, "")
    reset_password = Page.Handler.make_with(["reset", ""], Rule.alphanum_string, identity, "")
    remember = Page.Handler.make(["remember"])
    about    = Page.Handler.make(["about"])
    welcome  = Page.Handler.make(["welcome"])
  }}

The error is located on the first line:

    main =     Page.Handler.make([])

but I'm afraid it is related to all my Page.Handler.make uses.

try to delay the call to Server.create(handler) (application.OPA on
make_with) using Scheduler.sleep or push

It didn't help ! Now I am getting multiple runtime error:

And here's the 457 line of the application.opa file:
