Ok thank you, that did the trick! It now
selects the correct option. From:

DropDownChoice component. This is the case: I have a form, I have a CompoundPropertyModel
attached to it to hold my domain object. This domain object is already filled with data
from the database, so I want this form to show the properties of the domain
object (because this form is used for editing a database record). In this case the domain object is an Employee. It
has a firstName, a lastName and a function. First name and last name are
Strings, but the function is a Function object (also a domain object). I was able to let the form show the firstName and
lastName properties by using RequiredTextField like this: add(new RequiredTextField("firstName",
String.class)); add(new RequiredTextField("lastName",
String.class)); But now for the function, I don't want to simply
show the function name there. I want to have a dropdown box there, with all the
functions from the database. So I used the DropDownChoice component, I added
it like this: add(new DropDownChoice("function",
functions, new ChoiceRenderer("name")).setRequired(true)); By the way, 'functions' is a
LoadableDetachableModel which represents the complete list of functions of the
database. It all works fine, it shows the drop down list in
the form with all the functions, but the problem is … it doesn't automatically
select the right function from it's list! So my question is: how can I let the
DropDownChoice by default select the Function of the Employee I am editing? (I hope I clearified my problem enough) Thanks, Tom -- -- |
