How to open a URL in the default browser via CC HTML Extension?

Question

Hi,
I'm trying to open a link via the default browser in a HTML Extension for Photoshop CC built with Extension Builder 3.
With the initial example the "/indext.html" it look like this:
<li><button class="default" id="btn_PHXS" onClick="onClickButton('PHXS')" disabled="true">Run ps code</button></li>
and I changed the code from "/ext.js" to:
...function onClickButton(ppid) {    var csInterface = new CSInterface();    csInterface.openURLInDefaultBrowser('http://www.adobe.com');}...
This is what the "/lib/CSInterface-4.0.0.js" looks like:
* Opens a page in the default system browser.
* @param url   The URL of the page to open. Must use HTTP or HTTPS protocol.
* @return One of these error codes:\n
*      <ul>\n
*          <li>NO_ERROR - 0</li>\n
*          <li>ERR_UNKNOWN - 1</li>\n
*          <li>ERR_INVALID_PARAMS - 2</li>\n
*          <li>ERR_INVALID_URL - 201</li>\n
*      </ul>\n
CSInterface.prototype.openURLInDefaultBrowser = function(url)
    return cep.util.openURLInDefaultBrowser(url);
Since "util" doesn't seem to be defined  I get the message:
Uncaught TypeError: Cannot call method 'openURLInDefaultBrowser' of undefined
Is the something missing?
Thx,

Hi Franklin,
Apologies for the delay but I have been trying to determine why this API is not been working. I have since discovered that, although this API is documented in the JS library, the behaviour has yet to be implemented into Photoshop CC. Offline I will try to determine why this API was included in the library when it was not ready but for the meantime, if you would like to open a browser, here is a workaround:
Instead of using:
//(new CSInterface).openURLInDefaultBrowser("http://www.adobe.com")
// Use the createProcess API to open a browser. The following shows a workflow in Windows to open Internet Explorer.  
var csInterface = new CSInterface();
var rootDir = "/";
var isWindows = window.navigator.platform.toLowerCase().indexOf("win") > -1;
if (isWindows) {
                    rootDir = csInterface.getSystemPath(SystemPath.COMMON_FILES).substring(0, 3);
var processPath = "/usr/bin/open";
  if (isWindows) {
    processPath = rootDir + "Windows/explorer.exe";
var url = "http://www.adobe.com";
window.cep.process.createProcess(processPath, url);
Apologies for this inconvenience but we promise to keep you informed when openURLInDefaultBrowser API is fully supported.
Kind regards,
