I am using struts 1.3 and tiles to develop web application,it is reloading leftmenu even after using tiles.can anyone please give some idea
Tiles won't help you if you want to reload some part of page only as purpose of tiles is to reuse across the presentation tier of an application.
you need to either use frames or dhtml layers to refresh part of a 'page'.
Angular.js is a good option.
If you are using tiles, it is bound to reload the page because tiles only works when the request is sent and the response comes from controller.
The way by which you can avoid reloading of menu in struts 1.x,2 is :-
1. You can use AJAX or a DWR calls to get the response.
2. Or you can use frameset to give the response.

Vaadin is mostly based on individual interactions such as clicking buttons or scrolling in a grid, rather than viewing pages. What you can still do is to use UI::addBeforeEnterListener to get an event before navigating to a new target. You can use a VaadinServiceInitListener to register that listener for all your UI instances.
For more information, have a look at this blog post that I've written on the topic.
I want to create a modal dialog wizard using spring web flow and dojo.
I searched for embedding the flow in a dialog using embedded mode. But I found very few examples related to this. In these examples, they used JSF dialogs and tiles framework to partially render a form.
Can we do this without using JSF and tiles framework but using jsp and dojo?
Can anyone help me to create a wizard embedded in a dojo dialog using spring web flow?
I wouldn't depend on the dojo framework I believe is no longer supported with webflow. Moreover, webflow wasn't really designed (without hacks) to be embedded inside modal dialogs. It was designed as a simple "flow" navigation from html page to page.
To achieve what you want you'll have to use jquery (or some javascript library) to interact with the current flow via ajax calls to predefined transitions/fragments and manually via javascript take the response html fragments returned by webflow contents and change the contents of your modal dialog box. You could argue this is a "hack" but this is how I achieved what you desire using webflow.
A user asked a similar question a few months ago and i provided a thorough answer explaining how to use webflow + ajax + transitions in dialog boxes.

I've noticed that sometimes liferay loads the content of a portlet using ajax. For example, we've done some heavy duty web content templates and sometimes I can see a loading spinner while rendering the page.
I know about ajaxable and render-weight properties in liferay-portlet.xml, but... how does liferay know whether to render a portlet content using ajax or not? and second question, is it any way to disable this feature for asset publisher and web content display portlets without changing liferay's internal liferay-portlet.xml?
By default ajaxable is set to true.
In order to modify this you can try updating the render-weight and ajaxable attributes using the class PortletPreferences.

I'm looking for a NodeJS MVC framework that allows rendering partial views on client side using Ajax (without whole page refreshing).
As far as I know, you can declare partial views on server with almost any Framework (Express, Sails...), but this will lead to refresh the whole page even if there's only a small portion of your page that really changes. This problem doesn't exist with a SPA Framework (this one would just load the partial html file in a container via ajax).
I believe Microsoft ASP.NET MVC was able to handle this case, by comparing the previous version of the page with the new requested page, and just returning the portion of the page that really changed. This may be time and CPU-consuming but it just works.
Is any Node MVC Framework managing a similar thing today ? Or is it mandatory to use an SPA Framework when a reactive user interface is required (without any whole page refresh) ?
Thanks in advance !
sails.js! It supports partials as you requested. You don't need to refresh the page, if you send ajax-request or handle the stuff via websockets dynamically.
I'm using tastypie + django + backbone.js . My application should be usable by more than one user at a time.
What I want to do is to show all users "live" changes on the database without having the users manually reloading the page.
Anyone around to point me in the right direction?
Thanks
To get this working in all major browsers you will have to periodically send an AJAX request to your server asking if any changes have occured.
In modern browsers you could make use ob web sockets to setup a PUSH service where the server can push those changes to your application or simply notify you about it.
(If you are using Backbone as an MVC framework anyway you might as well step back from the idea of reloading the page and just request your data using AJAX and use Backbone's View component to render your data into HTML elements)
