'undefined' like 'undefined variable'?
I would expect some bug in the javascript where a variable is undefined 
instead of empty. or better: where an attribute is written, so the value 
is not filled at all.
maybe the condition tests the variable against empty string and the 
access to the undefined variable returns (by automatic typecasting) the 
string 'undefined' which is inserted afterwards.
