This is of course disallowed, which I discovered only after nearly completing my spanking new ajaxified UI. What is the motivation behind this, and what is the best workaround? This UI does a scriptaculous drag-and-drop of items from a first div (div1) over to a second div (div2), which triggers the contents of div2 to be updated to reflect the drop. No prob, thus far. But then the contents of div1 must be re-sorted via controller (action1) based on what has been dropped into div2. THe re-sort of div1 must be done server-side. I currently update div2 via render :partial on the tail-end of the action (action2) that is triggered by the drop, and then re-sort div1 via a submit (form_remote_tag) to trigger action1 which does the sort and refreshes div1. It would be nice to be able to either update both div1 and div2 from one of the actions, or allow action2 to update div2 via render :partial and then redirect_to action1, but that is not allowed, so what is the best recourse to having to use a submit?

are you using RJS templates? using RJS you can update as much as you want on a page. # action to call when element dropped into div2 def drag_item # do your work here render :update do |page| page.replace_html "div2", :partial => ... page.replace_html "div1", :partial => ... end end

Is there a simple way to check for the existence of a partial before displaying it? I have some code that creates a dynamic partial depending on the city a particular object is located in. There are some cities that do NOT have partials defined for them, but I still want the overall page to display. Is there a way to either chefck for existence before displaying (enclosed in an if statement?) or to tell the partial to skip if it cannot find the file? <%= render :partial => 'listing/partials/additional_' + @city %> Thanks, Mark
