Re: Managing database connection?
Most folks use open session in view filter from Spring (in combination with Hibernate). I think they have a similar filter for JDBC template (which is highly recommended for normal JDBC actions IMO).

Problem on external LoadableDetachableModel class
@SpringBean
private ProductManager productManager;
//@Autowired
public void setProductManager(ProductManager productManager) {
this.productManager = productManager;
}
.
LoadableDetachableModel personListModel = new LoadableDetachableModel() {
@Override
protected Object load() {
return productManager.getProducts();
}
};
add(new ListView(products, personListModel) {
});
It's ok.
While if a use an external class:
package wicketapp.util;
import org.apache.wicket.model.LoadableDetachableModel;
import org.apache.wicket.spring.injection.annot.SpringBean;
import springapp.service.ProductManager;
public class ProductModel extends LoadableDetachableModel {
@SpringBean
private ProductManager productManager;
//@Autowired
public void setProductManager(ProductManager productManager) {
this.productManager = productManager;
}
protected Object load() {
return productManager.getProducts();
}
}
..
ProductModel personListModel = new ProductModel();
add(new ListView(products, personListModel) {
...
});
It's wrong.
Which is the problem?

Create a custom request cycle that opens a Session in onBeginRequest and closes it in onEndRequest. Perhaps DataBinder.net has one readily available.

how is a custom request cycle heavy weight? It isn't–it's a common practise. Martijn On Sun, Aug 3, 2008 at 2:28 PM, Martin Makundi [EMAIL PROTECTED] wrote: Anything lighter?

Re: Managing database connection?
how is a custom request cycle heavy weight? It isn't–it's a common practise. Ok :) I just had a look at DataBinder.net, that was more heavy-weght. Is there any short introduction available on how to implement onEndRequest() -hook, or is the best reference to just have a look at the respective code of DataBinder.net? ** Martin On Sun, Aug 3, 2008 at 2:28 PM, Martin Makundi [EMAIL PROTECTED] wrote: Anything lighter?

Hook for hiding columns of DataTable?
I've perused the source and can't find an easy way to do this. I'm hoping
that maybe someone else has done it.
In an app for one customer, I have a table that lists parts that could be
purchased. It is a subclass of DefaultDataTable. I pass it in a custom
sortable data provider that wraps a list - so it has all parts in a list.
Then, I have filters above the table that can filter the list to a specific
category of parts. But if you filter down to a certain category of parts,
some of those columns will be completely empty. It would be nice to hide
them. But the table was already created - and it operates off of a static
array of columns. The column doesn't provide an isVisible mechanism. Is
there an easy way to hide it, or does the table need to be recreated and
replaced within the ajax link?
The current code is basically like this:
final ListSortableDataProvider dp = new
ListSortableDataProvider(listOfParts, columnToSortOn);
final PartInfoTable table = new PartInfoTable(table, new
VendorColumnFactory(vendor), vendor, dp);
add(table.setOutputMarkupId(true));
AjaxFallbackLink filterLink = new AjaxFallbackLink(link) {
private static final long serialVersionUID = 1L;
@Override
public void onClick(AjaxRequestTarget target) {
OrderVendorColumn column = (OrderVendorColumn)
nextFilterableColumn.getObject();
String valueToFilterOn = (String) item.getModelObject();
mPartFilter.addFilter(column, valueToFilterOn);
dp.setList(mPartFilter.filterPartsList(parts));
if (target != null) {
target.addComponent(table);
target.addComponent(LookupPartsPage.this.get(currentFilter));
target.addComponent(LookupPartsPage.this.get(addFilter));
}
}
};
filterLink.add(new Label(label, item.getModel()).setRenderBodyOnly(true));

Clear all sessions?
Hello! Is there any way to clear all the session/state data for all users ? I have tried implementing an ISessionStore (SecondLevelCacheSessionStore) that hangs on to (wicket) Sessions between onBind and onUnbind. When I want to clear then, I call invalidate() on all sessions. This does not work because invalidate() needs to be called within the Request for that Session. Any ideas?

Re: users, please give us your opinion: what is your take on generics with Wicket
Just started using the half-way approach and I really miss the type safety of generified Component. 1) Generifying* Wicket [X] Can best be done like currently in the 1.4 branch, where models and components are both generified. I care most about the improved static type checking generified models and components give Wicket. 2) How strongly do you feel about your choice above? [X] Whatever choice ultimately made, I'll happily convert/ start using 1.4 and up. -- View this message in context: http://www.nabble.com/users%2C-please-give-us-your-opinion%3A-what-is-your-take-on-generics-with-Wicket-tp17589984p18800407.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
