for(final AuditProgramDocument auditProgramDocument :documents){
models.add(new
LoadableDetachableModel<AuditProgramDocument>(auditProgramDocument){
Long sysDocumentId;
{
sysDocumentId=auditProgramDocument.getSysDocumentId();
}
@Override
protected AuditProgramDocument load() {
return auditProgramDocumentService.getById(sysDocumentId);
}
});
}
add(new ListView<IModel<AuditProgramDocument>>("documentsList",models){
@Override
protected void populateItem(ListItem<IModel<AuditProgramDocument>> item) {
AuditProgramDocument
auditProgramDocument=item.getModelObject().getObject();
item.add(new Link<Void>("view"){
@Override
public void onClick() {
System.out.println(getParent().getDefaultModelObject());
*AuditProgramDocument auditProgramDocument=
(AuditProgramDocument)getParent().getDefaultModelObject();*

Use DataView or take a look at how PropertyListView creates a
CompoundPropertyModel for each listitem.

That I get it from the database but my question is when user clicks on a
particular Item ie AuditProgramDocument I want to reload this as its
auditProgramDocument.getDocumentBytes() is lazy , In refreshing view I can
reload each item but why not in listview ?
