It's not a hash code, its a unique id. Because Tapestry is having to render the page piecemeil, across a series of Ajax requests, it can't know what ids are already taken when it is trying to generate unique DOM ids for elements, therefore, an Ajax request gets a namespace: this timestamp as a hex string. The namespace is encororated into any ids generated by PageRenderSupport during an Ajax partial markup render.
