Select control

Hi guys;

When i have an object say User, that has an association another object say,
Role, I want to display the list of roles in a dropdown.

Do i have to get my roles and then construct option objects ?

Is there a way the select component construct the options based on the List
of objects passed through the data provider?

regards.


Josh.

Hi Josh,

there is the method addAll(Collection, String, String) which is pretty
handy for initializing Select controls.

http://click.apache.org/docs/click-api/org/apache/click/control/Select.html#addAll(java.util.Collection,
java.lang.String, java.lang.String)

Thanks Gilberto;

I was already doing according to the examples. I was just wondering if
there is a more automatic way of initializing a select using a list of
object without having to loop through the list and adding options.

The docs about select[1] has some goods examples. I've done some
experiments using JPA[2], maybe it could help as well.
