relationFn will hold the value of the id. 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. So that means that the returned selected item will be the id of entity in this case? In my example MyClass.relationFn will have the type of the id of entity? And if I want to display more than one string is it possible to do something like this: SelectItem item = new SelectItem (string to display, string to display, id of entity) ?
