16980	Empty Values are ignored by class-ixr.php	nprasath002		"I tried to fix the following bug #10599 
Found out when you send and empty value via xmlrpc it converts it to null value.

 Say you send and array of arguments for mw_editpost, set

{{{
$content_struct[mt_keywords] = '';
}}}
 
IXR client passes a null value instead of an empty value.

In mw_post method consider this statement 

{{{
$tags_input = isset( $content_struct[mt_keywords] ) ? $content_struct[mt_keywords] : null;
}}}


Even if you send an empty value this statement fails because 


{{{
$content_struct[mt_keywords]
}}}
 
is set to null by IXR client."	defect (bug)	new	normal	Awaiting Review	XML-RPC	3.1	major		dev-feedback has-patch
