It should work. Do you have a test case that we can use to reproduce the issue? Was the server just plane JSaddle (or have you added servant or anything else to it)? Was it using the JSaddle debug
function? What other libraries were being used?
One thing that might cause problems is if JSaddle, other libraries or your app are using unsafePerformIO
to create singletons. JSaddle does use this trick, but only in places it should be safe. For instance it has jsNull = JSVal . unsafePerformIO $ newIORef 0
. This should be ok because the IORef inside any JSVal should be immutable (it is an IORef so we can attach finalisers for the JSVals that need to be freed on the JavaScript side).

Thank you for this very quick response. I have a test case, but it is far from minimal, I will try to provide a minimal one and will prepare and post instructions for the not so minimal case in the meantime.
I was not using the JSaddle 'debug' function. Other libraries used:
aeson
attoparsec
base64-bytestring
bytestring
Cabal
containers
data-default
directory
errors
filepath
generic-deriving
ghcjs-dom
gonimo-common
http-types
jsaddle
jsaddle-dom
jsaddle-warp
lens
lifted-base
mtl
reflex
reflex-dom
reflex-dom-core
safe
text
time
transformers
transformers-base
wai-middleware-static
warp
websockets
At least my code does not make any use of unsafePerformIO.
Servant was not added, just a middleware serving static files, code is here.

Ok, I am no longer able to reproduce this issue. Really weird, maybe my system just needed a reboot.
