Re: [Htmlunit-user] ActiveX support

[Brad C. <yo...@br...>]

HtmlUnit's ActiveX support is really just a way of allowing pages with ActiveX
controls to load without mock objects, not loading the real controls (unless you
make an object that does that). A good example is the unit test for this:

http://htmlunit.sourceforge.net/xref-test/com/gargoylesoftware/htmlunit/javascript/JavaScriptEngineTest.html#755

SSL is also a bit of extra work to set up:

http://htmlunit.sourceforge.net/jsse.html

You've also hit a known bug when using setTimeout recursively:

http://sourceforge.net/tracker/index.php?func=detail&aid=1103735&group_id=47038&atid=448266

I would suggest setting up jsse and making a mock object for your control that just
always say that SSL is ready. You might also consider using setInterval in your web
page instead of a recursive setTimeout.
