Grails：相同的页面，但用webflow更改_theTemplate

I am fairly new to web development, new to Grails, and would love some help. I want to know if it is possible to have a Grails webflow that doesn't actually change the page as the state changes, but instead changes a template within the page. Is this possible? If so, can you help point me to a tutorial, or give me some advice and very basic code samples of how to pull it off? Even just pointing me to a tutorial somewhere else (I couldn't find one) would be a great help.I am fairly new to web development, new to Grai
