Hi! I'm creating a mixin that hooks on to the onchange event of a Select and AJAX-submits the value. Other types of Select-boxes that has an onchange event without having an interesting value to submit is a common pattern in my application. For example a select that opens a popup window.
I've seen a couple of relevant Mixin-examples on the Wiki, in the Autocomplete mixin, and other places and they all use the same approach where a GET-parameter is added to the Ajax.Request and read as request.getParameter() in the Mixin class. Obviously there is no need for the value-binding of the Select here because this value is never set and never read. Right now I'm using a "Hijax" approach, where there's a chance the user won't be getting the AJAX-functionality, but rather the original onchange event that refreshes the page. In that case I will need to bind a page property to the value parameter. But if there's no alternative to AJAX that makes sense, I still have to put a dummy property in my form to bind to the value parameter of the Select. Is there any way to avoid that without writing my own copy of the select component? Regards Inge
