ExtJS 4 with Spring MVC Example

Introduction When developing a brand new application for the company I work for, one of the first thing I implement is "authentication". Not only is this process generally a prerequisite to access many other functions but it is also very simple and covers every layer of an application, from GUI to the database. So instead of another minimalistic "Hello World" tutorial, here is a "Login/Password" example, using 2 famous technologies : Spring MVC and ExtJS 4.   Prerequisites Because this tutorial is quite long, I won't go into the details of each technology I used but I will mainly focus on how ExtJS and Spring can be nicely used together.

I found an issue where loadMask z-index DIV element conflicted with modal window object z-index DIV element. loadmask component created for different target views for each screen and hidden but not destroyed. I spend good time to investigate issue in my application code. Version: EXT 4.2.0 Chrome - Browser Issues: var myMask = new Ext.LoadMask(mypanel , {msg:"Loading..."}); myMask.hide(); // Why myMask.hide(); simply destroy LoadMask instance, here DOM still exist in browser with style "visibility: hidden" Like this for more DIV element with this style are added to DOM. To work on my fix, I still see 'x-mask' element exist in dom even when my target view is destroyed.
