How to create and use checkbox list

[NicolasPeeters]

Now I can answer. They aren't. I guess that this is because I'm using java.util.Set. Maybe I should use an indexed Collection?

Well, an ordered Set would certainly be a good start

The other reason is that you are checking the ${status.value} which is the entire Set, which in turn calls getAsText() which (as previously discussed) returns null

What I tend to do (as described in my original FAQ post) is create a map in reference data which contains all possible selections, the key is the object (Customer) and the value is a boolean to indicate whether it should be preselected.

There is now as of Spring 2.5.0 a very simple way to handle collections of checkboxes and radiobuttons.

in Spring 2.0.7 you can't do

<c:forEach var="interest" items="${interests}">
<frm:checkbox path="interests" value="${interest}" />
<c: out value="${interest.name}" />
</c:forEach>

where items="${interests}" is the complete Set of things people may be interested in and path="interests" is the Set of things a given person is interested in. The reason, I think, has to do with this post: http://opensource.atlassian.com/proj...rowse/SPR-3704.

Thankfully this has been fixed in Spring 2.5.0 and in addition there is a new shorthand method (mentioned in this post: http://opensource.atlassian.com/proj...rowse/SPR-3882:

<frm:checkboxes path="interests" items="${interests}" itemLabel="name"/>

Things to note:

1. Make sure your object has a proper equals() method or it won't work.

This is one of those issues I'm glad I spent time trying to figure out because none of the alternatives were very good.
