Multiple select
All,
I cannot get my select to preselect items from groupList using
user.groups. This is my select:
<s:select label="group" multiple="true" size="4" name="user.groups"
list='groupList' listKey="id" listValue="name" />
This is the actual contents of groupList, and user.groups. Both
collections are List<Group>.
groupList: bmg 1
groupList: wholesale 2
groupList: repair 3
groupList: ebiz 4
groupList: actuate 5
user.getGroups(): bmg 1
user.getGroups(): wholesale 2
I am using struts 2 version 2.0.14. Any help would be appreciated.
Please let me know if I can provide more info. Thanks.

Once again I'll post my suggestion that the %{} notation be used
EVERYWHERE you expect the framework to evaluate your expression with
OGNL so that these are less confusing during subsequent development or
maintenance.
The "unusual" syntax you describe is an example of the power of OGNL.
caseFile.sentences is a collection of objects, but what you want is a
collection of just one field from each of those objects. The OGNL
documentation calls this "projection":
http://www.opensymphony.com/ognl/html/LanguageGuide/projection.html .
I don't have much experience with other EL's...is this type of construct
possible with the others that people have been suggesting (JUEL, MVEL,
etc.)?

Thanks Eric for posting your solution, this helped me remember that unusual
OGNL syntax on the value attribute.
Because I have not found so many working examples out there, I'll post mine
too:
<s:select
label="%{getText('caseFile.sentence')}"
name="caseFile.sentences.qualifierId"
value="caseFile.sentences.{qualifierId}"
list="availableQualifiers"
listKey="qualifierId"
listValue="display"
emptyOption="false"
multiple="true"
theme="css_xhtml"
required="false"
cssClass="text medium"
cssStyle="width:300px" />
CaseFile contains List<Qualifier> called 'sentences'.
Qualifier looks like
private Long qualifierId;
private String code;
private String description;
// Transients
private String display; // Just transiently defined as code + " - " +
description
Thanks -

Figured it out in case anyone has this same issue. Added a value
attribute, and used OGNL to grab a list of id's from List<Group> instead
of just the List<Group> which works just fine in a select where
multiple="true".
<s:select label="group" multiple="true" size="4" name="user.groups"
value="user.groups.{id}" list='groupList' listKey="id"
listValue="name" />
-Good luck
