Classic use case: a user chooses to view/edit and object by clicking on a link. This causes the app to fetch an edit view (form) and render it asynchronously, probably rendering it as a modal dialog. To specify the case a bit more, consider a table of like objects that allows you to edit them (orders or accounts). As far as the user experience, clicking edit for one would yield the same edit form as any other - only the contents (the target of the edit) would change.
Normal ajax forms in lift are simple - just wrap the bind in an ajax form (http://is.gd/4Z61Z) and you get an async submit with essentially the same template code. But what about ajax forms delivered by ajax? What's the best way to implement this in lift? It seems like there are two routes: client and server-based. 1) In the client-based approach, I can declare an invisible form in the template, as well as write some static javascript to do the heavy lifting (no pun intended). This JS would be responsible for receiving the data representing the object to edit from the server as json, unpacking it into the form for editing, rendering the form, handling the submit as ajax, and finally hiding the form. This means writing a good bit more JS by hand, but it keeps the (compiled) snippet code smaller. Ordinarily I'd see that as good, but more and more snippets seem like they are intended for such heavy view meddling. 2) The server-based approach would require very little of the main template: basically just a containing element (w/ dom id) to host the delivered form. The snippet itself would yield a form on an ajax call via SetHtml. It would also have to set up the handlers and populate the form contents with the target object. This is the part that I'm not clear on. I know I can just inline the XML with bind points as if it were in a form, but that just feels strange. Would it make more sense to use an external template, similar to a rails partial? Is there a template loading facility for this?
