Re: [Wicket-user] Hibernate Paging
Yeah, I think there's a lot that can be done with ejb3/jpa, and I know that people are more comfortable with standards approved by Sun than they are with the Hibernate name. (There are some useful HibAnno relationships that didn't make it into the spec, tho.) Seems to me like validation and possibly bean editing using jpa annotations would be a great Wicket sub-project (or projects). But actually loading and persisting the data is a separate concern, right?

Re: [Wicket-user] Hibernate Paging
Oh well, I find it very good to stirr up such a discussion. In fact I think that the ejb package could be just what the doctor ordered for this in particular. javax.persistence while not the end-all-be-all of ORM, does have annotations for all conceivable relationships. This would make such scaffolding pretty standard and possibly easy (easier?) to achieve. The biggest hurdle then becomes validation and tweaking of the beanedit panel (which fields do you show and which not, providing labels for the fields).

Re: [Wicket-user] Hibernate Paging
Experience with creating a "databinding" API... hmmm... Hey, there's actually an implementation of DataView paging using criteria here: http://databinder.net/site/show/baseball-players (sorry I haven't kept up with my listserv reading) So, I wonder what could be done in terms of generic databinding that would make everyone happy. I kind of think it is impossible, just because people have such different opinions about it, and those opinions are always in flux. I'm certainly interested in someday supporting Cayenne through Databinder, but it will be a pretty major refactor, and even then I don't see it being possible (or desirable) to abstract-out the differences between persistence libraries in any particular layer. Instead you might have flavors of the toolkit that work similarly, and share common interfaces where possible and useful. As for scaffolding / beanviews or whatever... the problem is those things never support complicated (but common) relations between objects. Rails scaffolding when I last checked was a one-table-only affair. So as much as that functionality looks good in demos, it has no use at all if your minimally useful datamodel already has basic connections in it. Nathan Eelco Hillenius wrote: > Thanks.

Re: [Wicket-user] Hibernate Paging
Thanks. I have to say that - now that I take a closer look after allmost a year - I am not particularly content with the contrib-data and contrib-hibernate packages. It works, but it could be much more elegant. It would be good to rethink the databinding from scratch, and come up with something really good and generic. And on top of that we could create a (t)rails-like package with generic object editing panels, ready-to-use datagrids etc. Any readers that have experience with creating a databinding API and want to join in on the effort?

Re: [Wicket-user] Hibernate Paging
It is meant for general use. I am not entirely happy with the pattern,
though I haven't come up with a better one either. You can override it
and have quite some options to customize. For example, this is from one
of my projects:
public final class ActivityListModel extends AbstractReadOnlyDetachableModel
{
/** action used by the pageable list (has our order columns). */
private CountAndListAction countAndListAction = new
CountAndListAction();
/** the list of matches */
private transient List list;
/** number of rows on each page. */
private final int rowsPerPage;
/** the venue for this model. */
private final Venue venue;
/**
* Construct.
* @param venue the venue
*/
public ActivityListModel(Venue venue)
{
this(venue, 14);
}
/**
* Construct.
* @param venue the venue
* @param rowsPerPage number of rows on each page
*/
public ActivityListModel(Venue venue, int rowsPerPage)
{
this.venue = venue;
this.rowsPerPage = rowsPerPage;
}
/**
* Add order-by field to query
* @param field the field to add
*/
public final void addOrdering(String field)
{
PageableList list = (PageableList)getObject(null);
if (list != null)
{
HibernateCountAndListAction action =
(HibernateCountAndListAction)list.getCountAndListAction();
action.addOrdering(field);
list.clear();
}
}
/**
* @see wicket.model.IModel#getNestedModel()
*/
@Override
public IModel getNestedModel()
{
return null;
}
/**
* Gets number of rows on each page.
* @return number of rows on each page
*/
public final int getRowsPerPage()
{
return rowsPerPage;
}
/**
* Convenience method to figure out if this model has any rows at all.
* @return whether there are any rows found
*/
public final boolean hasResults()
{
List results = (List)getObject(null);
return (!results.isEmpty());
}
/**
* @see wicket.model.AbstractDetachableModel#onAttach()
*/
protected void onAttach()
{
if(venue != null)
{
list = new PageableList(rowsPerPage, countAndListAction);
}
else
{
list = Collections.EMPTY_LIST;
}
}
/**
* @see AbstractDetachableModel#onDetach()
*/
protected void onDetach()
{
list = null;
}
/**
* @see wicket.model.AbstractDetachableModel#onGetObject(Component)
*/
protected Object onGetObject(final Component component)
{
return list;
}
/** count and list action that works with this model. */
private final class CountAndListAction extends
HibernateCountAndListAction
{
/**
* Construct.
*/
public CountAndListAction()
{
super(new HibernateSessionDelegate());
}
@Override
protected void setParameters(Query query, Object queryObject)
throws HibernateException
{
query.setEntity("venue", venue);
}
@Override
protected Query getQuery(Session session)
{
Query query = session.createQuery(
"select act from " + Activity.class.getName() +
" act.venue = :venue");
return query;
}
@Override
protected Query getCountQuery(Session session)
{
Query query = session.createQuery(
"select count(act) from " + Activity.class.getName() +
" act.venue = :venue");
return query;
}
}
}
public final class HibernateSessionDelegate implements
IHibernateSessionDelegate
{
/**
* @see
wicket.contrib.data.model.hibernate.IHibernateSessionDelegate#getSession()
*/
public Session getSession()
{
return ((BwhRequestCycle)RequestCycle.get()).getHibernateSession();
}
}
It's a bit verbose, but it works.

Yes, currently it is only in CVS. This weekend would be a nice moment to have proper releases for them as well I think.

Re: [Wicket-user] Hibernate Paging
Yes, is it does. PageableList is the the object that has the magic in it. It reads only the 'window' that it is currently in, so you don't end up with your whole database in memory.
