Thanks. I ran your example with elm-reactor and it worked, so at least I
could be sure it wasn't elm's fault.
But the code wasn't significantly different than mine. So I started
stripping code out of my program to identify the source of the problem.
Stripped it down to nothing without success. But I was hosting it on an
ASP.NET MVC development server. So I finally ran the simple version with
elm-reactor and it worked from elm-reactor but not from ASP.NET MVC hosted
webpage.
I finally found that the problem was coming from how I was loading the elm
script in the ASP.NET page.
I had been loading the elm script with this line:
@Scripts.Render(System.Web.Optimization.BundleTable.Bundles.ResolveBundleUrl("~/bundles/distjs",
true))
instead of
@Scripts.Render("~/bundles/distjs")
Which has the nice effect of letting me simply reload the webpage to update
my elm script, instead of restarting my server. But it has the downside of
breaking certain aspects of Elm's rendering process. Was extremely weird
and hard to pin down.
