[FX.php List] Error 504 not returning recid?!?

[Gjermund Gusland Thorsen]

 "504" => "Value in field is not unique as required in validation entry options

Array ( [data] => Array ( ) [linkNext] => [linkPrevious] =>
/makeNewDepartment.php?skip=0& [foundCount] => 0 [fields] => Array ( )
[URL] => http://user:password@10.215.87.220:80/fmi/xml/FMPXMLRESULT.xml?-db=CosaNostra&-lay=Department&-max=all&deparmentKey=sh8607212345&-new
[query] => [errorCode] => 504 [valueLists] => Array ( ) )

I know I have complained about this before... first of all foundCount
is at least 1 in this case...
but the problematic part is that it does not return the recid for the
the record that prevented the FMNew() to run,
most likely I would like to do an FMEdit() on the -recid that
prevented FMNew() to run?!?

Well, anyone got a solution to this?
