Retrieve boolean value from ConfigurationDialog

I'm finding the use of Groovy scripts, and the ConfigurationDialog, to be a great way to put together a complex test scenario, but I'm unable to figure out how to get the value of a checkbox. In the ConfigurationDialog I am able to add a CheckBox, and have it initially checked based on some properties default value. But I haven't been able to figure out how to determine it's checked status once the ConfigurationDialog is closed.


Thanks,
