[fw-general] Does Zend_Json_Expr work?

[Deanna Bonds]

I tried enabling Zend_Json::$useBuiltinEncoderDecoder = true;  and using 
json context switching.  When ever I try to send an Zend_Json_Expr('js 
code here');  it comes out   

"handler":{"__className":"Zend_Json_Expr"}
in the output.  I have tried disabling multibyte utf-8  settings.  I tried 
moving the object around just to
see if I had it nested to deep before.  Nothing seems to make it output the javascript code.
