Hi Laurie,
My JPA query is like that
Query query = em.createQuery("*SELECT c.name, c.id FROM Group c ORDER BY
c.name*");
List<Group> resultList = query.getResultList();
My "resultList" have all the values.It has the list of rows of id(numerical)
and name(string). "Group" entity has "id" of long type
and "name" of String type.
In Action class I have *resultList *and *groupId *declared with getter and
setters
*private List<Group> resultList ;
private long groupId;*
In JSP I have written like that :
1) If I write like this :-
*<s:select name="groupId" list="resultList" listKey="id" value="%{groupId}"
/>
*"resultlist" is being displayed in drop down box. But the value not getting
selected according to the "groupId" value.
*And if I submit this, it throws error that invalid field value for the
field "groupId".*
2) If I write like this :-
*<s:select name="groupId" list="resultList" listKey="id"
listValue="name"value="%{groupId}" />
Nothing is being displayed!!...*
Do I need to write setters and getters for "id" and "name" fields in Action
class.
I did that too.But nothing effects.
How you would like to do that?
