[FX.php List] Problem with checkbox set validation

[Edward L. Ford]

I did look at a copy of $_SESSION (the data is stored there), and the  
values are exactly as they are expected.  There's nothing outside of  
the ASCII character set used.  What's weirder is that through PHP,  
this works fine, no error, on NEW records, and only sometimes.  But  
when editing a record, it never works.
