TYPO3 Core

At the moment, the class can't render any of the following values:

• "" (an empty string)
• 0 (0 as an integer)
• 0.0 (0 as a float)
• "0" (0 as a string)
• NULL
• FALSE
• array() (an empty array)
• var $var; (a variable declared, but without a value in a class)

I think it's okay for some of them, but I like to be able to return something like:

{"effected_rows":0}

That's not possible at the moment, because calling:

$ajaxObj->addContent( 'effected_rows', 0);

Issn't saved, because 0 is an "empty" value and not saved.

Everything takes part at the method: http://api.typo3.org/typo3v4/current/html/class_8typo3ajax_8php_source.html#l00119

I think this is a missing "feature" or more a bug.
I hope you will fix this. It's not a big thing.
