Re: Wicket Offline Applications
hmm, you have a point here.however, every requirement is different. I know that it may sound weird, but still I believe that it depends on the nature of the application. There are lots of types of applications that banks use. Some I know would have to always have a central server managing it. There are different types of Technical Architectures that we cater for in our applications. There are some applicationms that always require online mode regardless adn there are applications that the user just needs to be able to view customer information ,etc actually it's hard to decide here. on the downside, I heard that GWT consumes a lot of resources on the client side, it's also a consideration. Failsafe servers are of course an option but again, the network is still a factor here. For example a very slow connection to the central server makes my productivity a lot less. Some places suffer from low bandwidth, unreliable networks, etc... I saw the value of distributed or offline applications that uses synchronization. It will be harder for the developers of course sicne they have to cater to two modes.

Re: Wicket Offline Applications
I would install failsafe cluster rather satisfying every client request about offline workability. You may end up implementing all the front-end and middle-end features in offline mode :) I believe offline mode should be used with care. The email applications are by nature offline. If you are certain that what the user does is offline by nature - implement it. If you have concerns that it should be involved into transaction (I mean a bit wider meaning than DB transaction) - implement it online and think about fail-safe servers. Concerning front-end and middle-end, AFAIK, every unit of work is a transaction which is done with multi-level authorization, including business authorization. You either implement all the authorization offline (insecure at all, and impossible in some cases) or defer authorization untill online mode (non-transactional). If a request of some client was satisfied (in offline mode) and then hasn't passed online authorization (for instance it violates some limits which can be thruly calculated on the server side only), you will have to call the client and tell him your appologises (or not directly you, then the bank. but the bank will then call you and tell you something awesome). Or just tell me the name of the bank. I will never become its client :) Carlo Camerino wrote: > > it's not for the public to use. but rather for people within the banks. > internal applications. sometimes central connection is not available. > > On Fri, May 1, 2009 at 9:37 PM, James Carman > wrote: > >> Are you sure a banking application would be the right place for a >> gears-based implementation?

LoadableDetachableModel onDetach() event
Hi everybody,
The detach() code for LoadableDetachableModel is this:
public void detach()
{
if (attached)
{
attached = false;
transientModelObject = null;
onDetach();
}
}
I have to invoke a model's method which releases resources, but it has
been set to null.
How could I do this?
I have to keep an extra reference to my object. Is not this better?:
onDetach(transientModelObject);
attached = false;
transientModelObject = null;
Just a thought.
Thanks!
Greetings,

Validation on Beans
hi, I'm using Wicket, Spring and Hibernate, and would like to have bean validation declaratively defined in the beans instead of in Wicket UI components. Hibernate has a bean validation framework called "Hibernate Validator", and Spring has validation framework that is part of the third party "Spring-Modules". Both use validation by annotating the beans. I like this approach, but how can I use it with Wicket?

a question regarding generics
Hi, We use at work Wicket 1.3.4 (going to 1.3.5) soon so we don't have any generic issue. I've created a Wicket project at home with 1.4_rc2 just to check it out (and do some testings). I've created a From and it asks for which is the model object type. I checked some discussions, especially http://www.nabble.com/generics-to18083910.html#a18083910 . But I bit confused. As I understand, if I have a bean that will be used in a CompoundPropertyModel, then I should put this as the T parameter, right? If I don't use a special model or a type in that model, what should I put? 'Object'? It's very easy for me to understand the generics for the IModel, but for the component, I'm still lost. I know it was discussed many time, but I would thank for any comment. Eyal Golan egola...@gmail.com Visit: http://jvdrums.sourceforge.net/ LinkedIn: http://www.linkedin.com/in/egolan74 P Save a tree.

Create the modalwindow outside of listview (in page). Set the the user
provided by item to the modal window.
That should do the trick.

Problem with Link,PopupSettings and dynamic window names
Hi,
In my application I have a "edit " link that opens a
popup-window where the user can actually edit "". Giving the
window a generic title (like just "Edit" ) would be confusing when
multiple pop-ups are open so I tried to make the popup-window title read
"Edit " instead.
My problem: The generated JavaScript looks ok but whenever I click on
the edit link the popup window that opens just shows the "Page expired"
page.
Thanks in advance,
Tobias
P.S. Here's what I (conceptually) try to do ( Wicket 1.3.5 ). The actual
code is slightly different and more complex but DOES work when I omit
the PopupSettings#setWindowName() call.
public class EditComponent extends Panel {
private final class EditForm extends Form {
private ThingToEdit thingToEdit;
private Link editLink;
protected EditForm(ThingToEdit someThing) {
super("form");
setThingToEdit( someThing );
// link that opens a new pop-up window
// where more complex properties
// of be edited
editLink = new Link("editLink") {
public void onClick() {
setResponsePage( new EditSomethingPage(
thingToEdit ) );
}
};
editLink.setPopupSettings( createPopupSettings( someThing ) );
add( "link" , editLink);
/* more TextFields etc. for performing simple updates */
}
private static PopupSettings createPopupSettings(ThingToEdit
thing) {
return new PopupSettings().setWindowName("Edit "+thing);
}
protected void setThingToEdit(ThingToEdit aThing) {
this.thingToEdit = aThing;
if ( editLink != null ) {
editLink.setPopupSettings( createPopupSettings( aThing )
);
}
}
}
public EditComponent(String id,List thingsToEdit) {
super( id );
final EditForm editForm = new EditForm );
/* render list of thingsToEdit where clicking on an item
will call editForm.setThingToEdit( ) */
}
}
