Serializing elements in the save() function fails which results in not be able to use the validate functionality

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a form with validation i.e. required fields
2. Submit it
3.

What is the expected output? What do you see instead?

I expect the error message when a required field is not filled in.

What version of the product are you using? On what operating system?

I use 2.2-php5, FreeBSD, PHP 5.2.9.

Please provide any additional information below.

I attached a working example which reproduces the bug.
I did some research and it seems that serializing $this in the save() function 
does not serialize the elements.
In this textfile i also copy/pasted the session info and serialized session 
info.

For I don't know what reason, the $elements variable of the main Form class is 
"private". Set it to "protected" and you'll be fine.
