Using [439]

When I set a context to hidden, hit update, the update is committed to the database, but the screen is filled with html (wrong content type?):

Element.update("container_context_4", "\n<div id=\"container_context_4\" class=\"list\">\n <div id=\"context_4\" class=\"context even_row\" style=\"display:'';\">\n <div class=\"position\">\n <span class=\"handle\">DRAG</span>\n </div>\n <div class=\"data\">\n <a href=\"/contexts/%40NICTIZz\" title=\"View context: @NICTIZz\">@NICTIZz</a> (13&nbsp;actions)\n </div>\n\n <div class=\"buttons\">\n \n <span class=\"grey\">VISIBLE</span>\n \n <a class=\"delete_context_button\" href=\"/contexts/%40NICTIZz.js\" title=\"delete the context '@NICTIZz'\"><img alt=\"Blank\" class=\"delete_item\" src=\"/images/blank.png?1171545177\" title=\"Delete context\" /></a>\n <a class=\"edit_context_button\" href=\"#\"><img alt=\"Blank\" class=\"edit_item\" src=\"/images/blank.png?1171545177\" title=\"Edit context\" /></a>\n </div>\n </div>\n <div id=\"edit_context_4\" class=\"edit-form\" style=\"display:none;\">\n <form action=\"/contexts/%40NICTIZz\" class=\"inline-form\" id=\"edit_form_context_4\" method=\"post\"><div style=\"margin:0;padding:0\"><input name=\"_method\" type=\"hidden\" value=\"put\" /></div> <table style=\"table-layout: fixed;\" width=\"450\">\n \n\n<tr>\n <td width=\"150\"><label for=\"context_name\">Name</label></td>\n <td width=\"300\"><input class=\"context-name\" id=\"context_name\" name=\"context[name]\" size=\"30\" type=\"text\" value=\"@NICTIZz\" /></td>\n</tr>\n<tr> \n <td width=\"150\"><label for=\"context_hide\">Hidden?</label></td>\n <td width=\"300\"><input class=\"context-hide\" id=\"context_hide\" name=\"context[hide]\" type=\"checkbox\" value=\"1\" /><input name=\"context[hide]\" type=\"hidden\" value=\"0\" /></td>\n</tr>\n\n <tr>\n <td width=\"150\">&nbsp; <input type=\"hidden\" name=\"wants_render\" value=\"true\" /></td>\n <td width=\"300\"><input type=\"submit\" value=\"Update\" />&nbsp;<a href=\"#\" class=\"form_reset\">Cancel</a></td>\n </tr>\n </table>\n </form> \n \n </div>\n</div>\n\n");
Sortable.create("list-contexts", {handle:'handle', onUpdate:function(){new Ajax.Request('/contexts;order', {asynchronous:true, evalScripts:true, onComplete:function(request){new Effect.Highlight("list-contexts",{});}, parameters:Sortable.serialize("list-contexts")})}, tag:'div'});
