xhr.listen not callable (xhr undefined) in core.js line 33 about cljs-http HOT 7 CLOSED

I tried version 0.1.8 - 0.1.10.

Hi jconti,

I can't find anything suspicious in your code snippets. I'm using
cljs-http as well with the :advanced and :none optimization
setting and haven't seen this so far.

If you can point me to a github repository with minimal
dependencies, that demonstrates your issue, I can take a look.

Thank you for the help r0man: https://github.com/jconti/cljs-http-question

I did spend some time in the debugger today looking at this, and could see no listen attribute on the Xhlro instance where it fails, just as the exception says. Looking at the Google Closure code didn't help much after following a few dead ends (my endpoint implements CORS, but that was not related).

Thanks again for any assistance.

Hi jconti,

the repository you provided doesn't compile properly. I get
warnings when I open the index.html file. Looks like some
version conflict. Can you try it again with this up-to-date
project.clj coordinates.

(defproject trans "0.1.0-SNAPSHOT"
  :description "FIXME: write this!"
  :url "http://example.com/FIXME"
  :dependencies [[org.clojure/clojure "1.5.1"]
         [org.clojure/clojurescript "0.0-2202"]
         [org.clojure/core.async "0.1.301.0-deb34a-alpha"]
         [prismatic/dommy "0.1.2"]
         [cljs-http "0.1.10"]]
  :plugins [[lein-cljsbuild "1.0.3"]]
  :source-paths ["src"]
  :cljsbuild {
     :builds [{:id "trans"
      :source-paths ["src"]
      :compiler {
        :output-to "trans.js"
        :output-dir "out"
        :optimizations :none
        :source-map true}}]})

This should compile. The next problem is that the URL you request
doesn't set CORS headers, so the request will not complete. Try
this url "https://api.github.com/users" instead of "http://www.google.com".

Hi Roman,

Thank you for looking into this. I had similar problems compiling on my MacOS box over the weekend, however on my Windoze box here at work I have no trouble at all compiling, but still no luck running:

$ lein version
Leiningen 2.3.4 on Java 1.7.0_45 Java HotSpot(TM) 64-Bit Server VM
```shell

The project was created with the latest Clojurescript template, which includes a newer Clojurescript compiler than the one you suggest:

```shell
lein new mies cljs-http-question

Also, yes this code does not do a CORS request. My comment was that I once suspected that CORS might be an issue, but all requests are broken for me. So in my snippet code I show a simple request.

Tonight I will look into the compiling problem on my MacOS box further. That may offer a clue. I will also step forward to Clojurescript 2202 on Windoze and see if that helps.

Thanks again,

John, are you using Lighttable?
Have you seen this:

suspected that CORS might be an issue, but *all* requests are broken for
me. So in my snippet code I show a simple request.

Tonight I will look into the compiling problem on my MacOS box further.
That may offer a clue. I will also step back a version on the Clojurescript
compiler here on Windoze and see if that helps.

Thanks again,
John

Roman,

I had not seen that. I am using the packaged light table binary, and lein from the command line. So I am not sure how LT's version could affect my problem. I am compiling with lein from the command line.

What I did was implement all your suggestions. In particular by just stepping up the Clojurescript version, I was in business. Thanks also for the link that implemented CORS. It didn't occur to me that google would not enable CORS. As soon as I upped the Clojurescript version I got the CORS warning, and I knew that the runtime was working properly again. Just putting in the github url then confirmed this.

I appreciate you helping out a Clojurescript n00b such as myself!

Best Regards,
John
