Yes you are right; I do not need to separate each String as I get the id directly. Sorry, Thanks for your help Sophie

So if the entity has the id 23, relationFn results in 23. Sorry, i have permuted the arguments; id comes first then the label (description). You can also concatenate the outputted String (string to display + " " + string to display), i don´t see a need for two arguments of display strings here. cheers, Gerald On 9/11/06, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote: > Thanks a lot.
