Re: [Htmlunit-user] RichFaces 4 fileUpload

[Parham, C. <cp...@bi...>]

Hi Ahmed,

Debugging the code, I have a call stack that is only two levels deep. I’ve taken browser screenshots of the code at fileupload.js#403 (where HTMLUnit says “e” is undefined) and another screenshot of the code calling fileupload from jquery.js#547.

The jquery code passes “arguments” as the parameter to fileupload.js. So I’m assuming that “arguments” is for some reason undefined when running HTMLUnit test. Why, I don’t know. Can you suggest something?

Thank you.

Hi,

You can use "alert(arguments.callee.caller);"

Please read some hints in http://htmlunit.sourceforge.net/submittingJSBugs.html#JavaScript_hints

Hello,

I continue to struggle to get the RichFaces fileUpload component to work with HTMLUnit 2.18.
(http://showcase.richfaces.org/richfaces/component-sample.jsf?demo=fileUpload&skin=blueSky)

After setting the file to upload with htmlInput.setValueAttribute and clicking the Upload button, I get this error from HTMLUnit:

2015-08-06 15:23:58,744 INFO  main [com.gargoylesoftware.htmlunit.javascript.JavaScriptEngine][handleJavaScriptException] Caught script exception
======= EXCEPTION START ========
EcmaError: lineNumber=[403] column=[0] lineSource=[null] name=[TypeError] sourceName=[https://bio206/saas/org.richfaces.resources/javax.faces.resource/org.richfaces/fileupload.js] message=[TypeError: Cannot read property "target" from undefined (https://bio206/saas/org.richfaces.resources/javax.faces.resource/org.richfaces/fileupload.js#403)]

…
== CALLING JAVASCRIPT ==
  function () {
      return fn.apply(context || this, args.concat(slice.call(arguments)));
  }
======= EXCEPTION END ========

I’ve tried debugging and all that I can tell is that “e” is undefined on this line #403 in fileupload.js:
switch (e.target.status) {

The function in fileupload.js is called from jquery.js but I cannot trace the argument to better understand why it’s undefined when HTMLUnit is running. I’ve attached a testcase.

Any suggestions?

Thanks,
Clint
