Have you verified that the query is returning a non-empty list -- i.e.
resultList really contains data to display? What does the result object
JPA produces for an ad-hoc query like that look like? I don't recall
off the top of my head, but I suspect it's something like
List<Map<String, Object>> or possibly List<Map<String, String>>?
In Action class I have *resultList *and *GroupId *declared with getter and
setters
private List resultList ;
private long GroupId;
In JSP I have written like that :
*<s:select name="GroupId" list="resultList" listKey="id" listValue="name"
value="%{GroupId}" />*
That should be 'groupId' not 'GroupId'; case is important, and the
convention is specified by the JavaBeans spec.
But nothing is displaying in my drop down box when I put listkey and
listvalue.
According to your previous reply on this thread, the options are
rendered correctly but none is selected. Is that right? That would be
explained by the mis-spelled 'GroupId'. If that doesn't fix it, make
sure the type of the groupId property matches the type of the 'id'
property in the JPA result object.
