Element not found after switching to iframe on SmartGWT using HTMLunitdriver

[vgattani]

I am not able to access the webelements due to https authentication issue(security). The issue got resolved using Phantomjs by using capability settings listed below:

**DesiredCapabilities caps = new DesiredCapabilities();
caps.setJavascriptEnabled(true);
caps.setCapability(PhantomJSDriverService.PHANTOMJS_CLI_ARGS, new String[] {"--web-security=no", "--ignore-ssl-errors=yes"});**

Question: Do we have any such settings for htmlunitdriver for ignoring SSL/ Websecurity?
