Re: [Wicket-user] More examples of sorting?
If you look at the Wicket Examples, the ones online, in the Repeaters
category (http://www.wicket-library.com/wicket-examples/repeater), many
examples show sorting, and you can download the working examples. The
second-to-last example demonstrates a DataTable with sortable column
headers. The example doesn't even use a RDMS -- it allows the user to
sort data that is stored in the application object. (That's where I got
the idea for my approach.)

I appreciate it Frank, however I'm not familiar w/ DataTable or the
SortableDataProvider - this is my first run. Really what I need is to
see sorting working and I haven't even gotten that far.
I'd be willing to take a lookit might be easier to see it working w/
plain JDBC to get a view of this w/ a different perspective, if
anything.
Thanks!

Re: [Wicket-user] More examples of sorting?
As an alternative - to see a complete working example that works with
Hibernate - you could look at wicket-contrib-examples,
wicket.examples.cdapp and SearchPage/ SearchModel in particular.
In general, we consider using one of extension's repeater classes to
be a better way to go in general, but the approach in cdapp works, and
is low level enough to hopefully give you some ideas on how to
approach this yourself.

Re: [Wicket-user] More examples of sorting?
Wow...ok...I'm making a total disaster of this. I can't help but
think there's an easier way. :(
I've got this method in what we could call a "dao":
public List getFiltered(int first, int count, String orderBy)
{
String query = "select i from Incident i order by :orderBy";
Query q = this.em.createQuery(query);
q.setParameter("orderBy", orderBy);
q.setFirstResult(first);
q.setMaxResults(count);
return q.getResultList();
}
And I've got started what might someday become a provider class:
public class IncidentsProvider
extends SortableDataProvider
implements IDetachable
{
private transient List incidents;
/**
* default ctor
*/
public IncidentsProvider(Integer first, Integer count, String orderBy)
{
this.incidents = myDao.getFiltered(first, count, orderBy);
setSort("openDate", true);
}
public Iterator iterator(int first, int count)
{
return this.incidents.listIterator(first); // - what do do?
}
public int size()
{
return this.incidents.size();
}
public IModel model(Object object)
{
return new Model((Serializable)object);
}
public void detach()
{
this.incidents = null;
}
}
As you can see, I'm trying to marry my provider to my DAO as closely
as possible...I'm not worried about elegance and cleanliness right now
- just trying to take it one step at a time and get it *working*.
I can make some sort of 'if asc then make desc' and vice/versa afterward
Sorry, it's been a long day...maybe I need a breaktwo or three
weeks ought to do it.

Re: [Wicket-user] More examples of sorting?
If your SLSBs were not coded with paging and sorting in mind, you'll
probably have to implement a layer that understands sorting and paging
to stand between your SortableDataProvider and your SLSBs. To do that
in an ad-hoc way relevant to one specific set of data is probably time
consuming at worst, but a general approach doesn't sound very easy to
me.
Is your data set too large to keep in the WebPage on the server while
your user plays with it, sorting it this way and that? Must you throw
away the data between postbacks, re-querying each time? If not, why
don't you take a look at the classes I posted to the group last week
(and sent you in private e-mail as well)? Even if you're not interested
in getting your data via vanilla JDBC SQL SELECT queries, I'm sure my
approach can be adapted.
My code is not difficult to read if you are at all familiar with
DataTable and SortableDataProvider. I'd be happy to answer any
questions. /Frank

Re: [Wicket-user] More examples of sorting?
then the only semidifficult part is the sorting - you need to come up with some utils that append the sort for you.as far as paging it would translate directly tosession.setFirstResult(queryparam.getFirst()).setMaxResults(

Re: [Wicket-user] More examples of sorting?
Well, I don't have DAOs in this particular project - it's an EJB3
project where I'm simply using SLSBs as DAOsso I have the
EntityManager to work from and I should be able to bring the two
together to facilitate this...
This may be easier than I thought

Re: [Wicket-user] More examples of sorting?
yep, you have to code your daos with paging and sorting in mind, it cannot be slapped on as an afterthought.let me give you some cluessee the attached QueryParam class, all my finder dao methods take it so that they can page/sort accordingly.

Re: [Wicket-user] More examples of sorting?
Currently I don't have anything like the ContactsDatabase class in
'examples' - I'm just pulling a list of data and displaying in a
ListViewbut it appears now that I'm browsing through I'm going to
have to create one and implement some of the methods like you have in
order to get paging/sorting.
I'll play w/ it...it was just a little more than I expected once I
started digging into it.

Re: [Wicket-user] More examples of sorting?
what could be simpler then the dataview? its just like a listview only instead of being fed off the list it is fed from the idataprovider.class mydataprovider implements idataprovider() { iterator iterator(int first, int count) {
return mydao.findcontacts(first, count).iterator(); } int size() { return mydao.countcontacts(); } model model(object o) { Contact contact=(Contact)o;
return new ContactDetachableModel(contact); //or return new Model(contact); }}and that gets you paging, sorting is like thismydataprovider extends sortabledataprovider {
// ditto from above iterator iterator(int first, int last) { return mydao.findcontacts(first, last, getsort().getproperty(), getsort().getcount(); }}if you have more specific questions i will be happy to help you
