Johan, Thanks for your speedy responds. But sadly speaking, we just decide to but a park on Wicket for now. But I continue to follow wicket closely to she how it helps solve some of our concerns. Hopefully Ajax Implementation of Wicket will be as easy and yet powerful at wicket right now. Thank you very much guy. As an early adopter of Struts/Tiles, I have to admit I am much more impressed With Wicket then I were with Struts at this state. --danny From: Johan Compagner <[EMAIL PROTECTED]> Re: Re: Howto generate additional inputs to existing ListView of inpu ts.. .. 2005-10-03 13:26 if you want a empty row then just add a Empty object (new Person() or something like that) in the model (list) of the listview Then after submit that new Person() object is filled Ajax is still in progress and moving ok.

Johan, Thanks for reply. What if I do this on the serverside. How would I do it in wicket to add empty row and render this to The client? Thanks, --danny Ps. Johan, how far do you see Ajax is coming? And plus if you switch to Ajax in wicket, would their Be much or portability issues? From: Johan Compagner <[EMAIL PROTECTED]> Re: Howto generate additional inputs to existing ListView of inputs.. .. 2005-10-03 03:42 as i said in other threads. When you dynamically adding things on the client side Then you have to do this loading of that data completely by yourself in youre Form.onSubmit() method. The wicket way (without ajax at them moment) you just have to go to the server there add a new record (new Person) so that the ListView makes an extra empty row and renders this to the client.

[Wicket-user] Howto generate additional inputs to existing ListView of inputs.. ..
Hi all, It’s 3am in the morning and I still trying to do something that seems simple… and yet impossible? Ok, I have a list of Person(s) that needs to be display in a Form for update and create. For update, I was able to update the existing data just fine. For create, my Form has a button, when click on it, it needs to create an additional row with inputs for All of the Person attributes. I first tried to use _javascript_ to create the new row with all the input fields empty. I used the Wicket’s path Patterns to generate these new input’s name( with new index for this new entry). And on the serverside, I Do as follow: · Created a new ListView that has populateItem(…) implemented. · Overrided newItem(…) and getListItemModel(…) so that newItem(…) returns a new ListItem that associated To a new ListItemModel(I extended), return by the getListItemModel(…) that I override. · The new ListItemModel I extended has onAttach(…) overrided with logic that would add new and empty Person object to the existing List of Person, that get from my ListView. getModelObject(…). Well this doesn’t work. The page did create additional row of inputs for the new person. But when I submit the Form, Nothing get update to the existing list and the page come back with just the previous data in the table and my new Person input is gone and no where to be found. My guess is, Wicket use the existing components in the page to get posted data. And since my new entry inputs Created on the client never exist on the server. Therefore, wicket does not know to go get it. If this is right, then how do I overcome this default behavior? And if it is impossible to add new inputs on the client Browser then How do I do it on the server? Meaning, how do I create the new inputs entries on the server so that wicket Can generate new inputs entry, and client can enter data and submit it.

[Wicket-user] Dynamic inputs generated by JavaScript...... ?
Hi all, I need to create a Form that has a list of input group, e.g. ListItem(s). The page has _javascript_ that will create New input group, that allow user enter addition info. My question is how do implement this on the server side, so that wicket knows there is addition nodes for the Existing ListViewModel. Meaning, if the new input group created on the client browser get submitted to the server. What do I need to do on the server to capture the new input data. Is there any name pattern needed to follow for Those new inputs, so that wicket know and create new node for the model. Is there any example like this out there? That someone can point me to?

[Wicket-user] wicket-contrib-examples does not build..... missing import wicket .markup.html.image.resource.BlobImageResource
Hi all, I just downloaded the wicket-contrib-examples lately and find out that it depends on import wicket.markup.html.image.resource.BlobImageResource in its EditPage.java. I couldn’t find import wicket.markup.html.image.resource.BlobImageResource in the rc1, b4, or 1.0.1 release either. Doesn’t anyone have any idea where this, import wicket.markup.html.image.resource.BlobImageResource, coming from?

[Wicket-user] BoundCompoundPropertyModel doesn't seems to work correctly....
Hi all,
I tried using the CompoundPropertyModel for my Form and it
works fine for me:
Class Person {
String
firstName ;
String
lastName ;
…. Getter/Setter….
}
Class MyForm extends Form {
Super(
id, new CompoundPropertyModel(new Person()) ) ;
add(
new TextField(“firstName”) ) ;
add(
new TextField(“lastName”) ) ;
….
}
HTML
…..
However, when I tried to use BoundCompoundPropertyModel as
follow:
Class PersonWrapper {
Person
person ;
….Getter/Setter….
}
Class MyForm extends Form {
super(
id ) ;
BoundCompoundPropertyModel
theFormModel = new BoundCompoundPropertyModel( new PersonWrapper( new Person()
) ) ;
setModel(
theFormModel ) ;
add(
theFormModel.bind(new TextField(“firstName”), “person.firstName”)
) ;
add(
theFormModel.bind(new TextField(“lastName”), “person. lastName”)
) ;
….
}
HTML
…..
Then I got RuntimeException:
ERROR -
RequestCycle
- Unexpected runtime exception [page = [Page class =
com.tickets.patron.web.PatronDetailsPage, id = 2]]
wicket.markup.MarkupException: Unable to find component with id
'firstName' in [MarkupContainer [Component id = patronForm, page =
com.tickets.patron.web.PatronDetailsPage, path =
2:boxBorder:patronForm.PatronDetailsPage$PersonForm, isVisible = true,
isVersioned = false]]. This means that you declared wicket:id=firstName in your
markup, but that you either did not add the component to your page at all, or
that the hierarchy does not match.
[markup
=
file:/C:/work/web/target/classes/com/tickets/patron/web/PatronDetailsPage.html,
index = 22, current = '' (line 41, column 108)]
But if I changed
the markup to its OGNL _expression_ like:
HTML
…..
…..
Then it works
just fine.
Can anyone
explain what is going on? Or if anyone can point me to a working example of
using the BoundCompoundPropertyModel.
I read the newUserGuide and wiki section on Model and it was
very simple and straight forward. However, I just couldn’t understand why
it wouldn’t work for the
Simple case I have. I tried to look into the example apps
and none are using the BoundCompoundPropertyModel. I am very frustrated and
really need OGNL expr
To work in order to use nested Domain model objects.
Thanks for any help,

[Wicket-user] Howto setResponsePage( Using an existing page ) ?
Hi all, Instead of setting response page using the page’s class and/or Parammeters.

[Wicket-user] How to reuse an existing page?
Hi all, It seems like every time you go to a Page, via click on a Link on a page or by setting setResponsePage(…) method You always create a new page. And this new page will end up added to the PageMap of the current Session. My question is, why do we have to create a new page every time? If no, we don’t have to create a new page every time Then How do you set response page to an existing page in PageMap? … and Is there any common pratices and howto Example that I can refer to? My reason for asking these question is because the overhead of constructing a new page on every single request can Be a performance issues and that I need to understand the issues to make recommendation.
