Rails spinoffs - Apr 2007 - New version does not pass empty POST variables using Ajax.Updater

I recently upgraded from prototype-1.5.0_rc1 to prototype-1.5.1_rc2
and discoverd, to my great suprise that prototype no longer passes
empty variables when using Ajax! Why in the world? That can''t be on
purpose. How am I to know that someone cleared a variable? Is there a
way to change this behavior?

It''s been discussed quite a bit recently (check the archives)

It''s not on purpose and it''s been fixed in svn.

Wait for either a new RC for 1.5.1 or 1.5.1 final, check out the code from svn,
or patch your local version.

Yes, use the latest version from SVN. This regression bug has been
patched.

I apologize for my ignorance, but what is svn?

Subversion. It''s the software used for the prototype source control.
You can
checkout the code now as it exists (not a real release) and it takes a little
bit of work to get it into a single .js file. Or you can wait for a full
release.

That''s Trac showing a nice HTML view of the Subversion repository, but
it''s not
Subversion itself.

Instructions for getting an svn checkout of Prototype can be found here:
http://prototypejs.org/download

But you''ll need to install subversion on whatever machine
you''re developing on.
This will differ depending on what OS you''re using (on most linuxes
it''s as
simple as "yum install subversion" or "apt-get subversion").
Google is your
friend here.

You also *really* need to use a source code management system for your own code
(if you''re not already).

svn is short for "Subversion", then name of a source control/ 
versioning application, designed to replace CVS.

Sometimes confusingly, the term "svn" is used to refer to a) the  
application itself [1], and b) the repository in which code resides.   
(In this case, the Prototype code)

There is a really good open source manual online. [3]

... also of interest, in the book "The Pragmatic Programmer" [4], the
authors recommend using version control (particularly svn) for every  
project you work on, whether for school, personal use, or work.

[1] http://subversion.tigris.org/
[2] http://dev.rubyonrails.org/browser/spinoffs/prototype
[3] http://svnbook.red-bean.com/
[4] Highly recommended for all programmers. http://www.amazon.com/gp/
