Question

I have users inside an ArrayList of UserDetails. UserDetails has 2 fields: id and name.

I would like to have a Struts2 select tag which populates the user names, but on the click of submit button it should post the user id.

s:select list="users.userName" value="users.userId" size="0"

This is what i did..but it is not working for me.

How can I achieve this?

Answer 1

just like @AleksandrM said, check the Document here

It should look like this:

<s:select list="users" listKey="userName" listValue="userId"/>
