The same StatefulSnippet instance is used across a given page rendering.
If the StatefulSnippet is used to render a form, a hidden field is added to the form that causes the same instance to be used on the page that is the target of the form submission.
If you want to keep the same snippet for a page rendered via a link (<a href...>) use the StatefulSnippet.link method to create the link. This will cause the registerThisSnippet method to be called and the same instance will be used on the target page.
class CountGame extends StatefulSnippet { val dispatch: DispatchIt = { case "run" => run _ } def run(xhtml: NodeSeq): NodeSeq = { if (lastGuess == number) { bind("count", chooseTemplate("choose", "win", xhtml), "number" --> number, "count" --> count) } else { bind("count", chooseTemplate("choose", "guess", xhtml), "input" --> text("", guess _), "last" --> lastGuess.map(v => if (v < number) v+" is low" else v+"is high").openOr("Make first Guess") ) } private def guess(in: String) { count += 1 lastGuess = Full(toInt(in)) } private val number = 1 + randomInt(100) private var lastGuess: Box[Int] = Empty private var count = 0 }
