Alan,

registerEvents is the main function that gets invoked on the client-side
javascript controller.
Either new / extend works.

With extending the base list view it gets the other function definitions
that can be invoked at sometime later.

WorldClock v1 example doesn't follow the same UI conventions as its parent
and hence does not invoke the parent method.

Have a look at few standard modules like (Contacts
<http://trac.vtiger.com/svn/vtiger/vtigercrm/branches/6.0.0/layouts/vlayout/modules/Contacts/resources/Detail.js>,
Rss
<http://trac.vtiger.com/svn/vtiger/vtigercrm/branches/6.1.0/layouts/vlayout/modules/Rss/resources/List.js>)
that does extend client-side controller.

Sublime vs Dreamweaver

By
13 REASONS TO USE OF SUBLIME TEXT OVER DREAMWEAVER 17 MARCH, 2014 BY TOM ELLIOTT I started writing this post over a year ago but back then it was entitled something along the lines of ‘Reasons why I use Dreamweaver over code editors’. This was biased, as I hadn’t properly explored other code editors like Coda, Sublime Text or Notepad++. So, wanting to write an objective post from a web developers point of view, and because I had heard many good things about it, I setup Sublime Text 2 and dove straight in. I’m glad I did because it quickly became obvious that my presumed reasons for Dreamweaver’s superiority were just wrong. We are all creatures of habit to a greater or lesser degree and when we develop workflows to help make our lives easier, we can get entrenched in the view that these honed practices are superior. It’s not our fault, confirmation bias is supposedly  programmed in our DNA . Even so, it’s healthy to try and keep questioning and challenging ourselves, espe...

Difference Between Primary Key and Unique Key In Sql Server

By
Both  PRIMARY KEY  and  UNIQUE KEY  enforces the Uniqueness of the values  (i.e. avoids duplicate values) on the column[s] on which it is defined.  Also these key’s can Uniquely identify each row in database table. Below table lists out the major  difference between PRIMARY KEY and UNIQUE KEY : PRIMARY KEY UNIQUE KEY NULL It doesn’t allow Null values. Because of this we refer PRIMARY KEY = UNIQUE KEY + Not Null CONSTRAINT Allows Null value. But only one Null value. INDEX By default it adds a clustered index By default it adds a UNIQUE non-clustered index LIMIT A table can have only one PRIMARY KEY Column[s] A table can have more than one UNIQUE Key Column[s] CREATE SYNTAX Below is the sample example for defining a single column as a PRIMARY KEY column while creating a table: CREATE TABLE  dbo.Customer ( Id  IN...
