Re: conditional markup change
there are a few ways to do this
one is to add both and override isvisible() on them to conditionally hide
one or the other
another way would be for that link to replace one with the other

Re: Can Panel replace itself ?

I've checked it with ff2 and ie7. Also with Wicket1.3beta2 and beta3. I've
set view.setreuseitems(true);
The problem is that the wicket generate span tags for panels after body tag
and before the table tag.
So replacing is proper, but the tags location is incorrect:
lt;bodygt;
lt;span id=panel5gt;
lt;/spangt;lt;span id=panel7gt;

Re: creating RSS feeds with Wicket
* Ryan Sonnek: http://www.jroller.com/wireframe/entry/wicket_and_rss_feeds Just wanted to post an announcement that there's a new wicket stuff project (wicketstuff-rome) to allow for creation of RSS (or Atom) feeds from within Wicket. I've been using it for the past several weeks and it's allowed me to integrate RSS feeds into my Wicket app *very* quickly. This new project is a definite step up from the existing wicket wiki article for Rss pages, but I'm not sure what to do about that info. Please let me know if anyone has suggestions or issues with the project. Now that it's on wicketstuff, feel free to tweak or add features!

Re: Component Factory and code against interface
We can do that because all our components implement specific interfaces
which changes
the state of the component. For example
interface ILabelMethods
{
setBackground(Color color)
setForeground(Color color)
// and so on
}
and all those implementations do record the change

Re: Wicket and Spring MVC compared.
There is not much point in comparing Wicket to Spring MVC. Spring MVC is a very simple action based framework with very little functionality (and probably minimal overhead). So what you would really be comparing is Wicket to JSP (assuming you use JSP as your view layer). Now again, Wicket is a full blown component based framework with advanced state management, while JSP is a simple templating engine.

AjaxEditableLabel onEdit
Hi,
in my testapp i'm trying to use an AjaxEditableLabel. When I put some data
in, it works fine but now comes my Problem.
My label is as Subclass of AjaxEditableLabel and so I tried to implement
the onEdit() function.
The thing is, that the displayed values might calculated by a formula in
the back.
If the user clicks on an editable Label the formula should appear instead
of the calculated value. How do i do this?
My first attemp looks like this:
protected void onEdit(AjaxRequestTarget target)
{
Position2 position = (Position2)pm.getTarget();
if(position.hasFormulas())
{
if(position.getFormula()[index] != null)
{
String output[] = position.getOutput();
output[index] = position.getFormula()[index];
}
}
target.addComponent(this);
}
The label is bound to an output property from the Position2 class.
This works fine so far. The deposited formula is displayed but not
editable any more.
What do I have to do to display the formula (if there is one) and keep it
editable?

Re: Wicket and Spring MVC compared.
Yes I see your point and you are absolutely right but please consider that a lot of companies (included mine) have been using Spring MVC for a long time and there are a lot of projects already in production using that technology and working fine with the IT infrastructure now available. Of course IT architects and managers want to know which impact a change can cause also to be able to perform the correct actions during the migration (more ram, improving the clusters, firing developers because with Wicket things are simple... :-) ).

In the database there are 50 elements and I wrote a JMeter script in which a request for each page is done (a CookieManager is used to create always a new session) , 10 threads are used with 1 sec of ramp up and 20 loops per threads. Each application is deployed alone in a JBoss instance. Then I launch the Jmeter script and use JConsole for the memory analysis. Something wrong with this? Any Suggestions (more elements in the db, more threads, more something...)?

Re: conditional markup change
Hello Konstantin,
Your code snippet is from panel constructor, is not it? So far it
executed only first time, by creating page!
Your need explicitly use in the link handler replaceWith() method. See
Component's javadoc.
Cheers,
Oleg.

so far so good, BUT, when I click on the AjaxLink
inside of those panels they change status of the

reflect the change - and THAT does not happens. It is
sort of understandable because component already has
been created...
But the question is: How can I do that in Wicket:
conditionally change markup and see effect of those
changes for Ajax updates too?

Re: Alternative to Wicket data binding
Hi,
there's nothing wrong with yor approach, actually, it's more solid

It's not out of date. PropertyModel provides access to privdate
properties and it is completely intetional. The reason is actually to
provide better encapsulation, because if you e.g. bind your component
to a property of that component, you don't have to provide public
setters and getters for that property (thus it can't be changed

Well, the private acessing functionality was mostly build with situation like
private String myField;
new PropertyModel(this, myField);
i.e. without the setters and getters functionality. But I don't see
reason why should getters and setters be ignored, even if they are
private. Johan?

Realised I've been avoiding implementing something because I can't think of

Re: Component Factory and code against interface
the ui layer is generally not portable. if you start building your own abstraction to make it portable you will end up with a pretty big mess because you will be working against whatever framework you are using and eventually that abstraction will turn into a framework itself. -igor On 8/24/07, Sam Hough [EMAIL PROTECTED] wrote: Many thanks Igor, that sounds like a very pragmatic approach.

Small guide on howto see the problem:
First select an option from the dropdown, after it have been selected
you cannot change it again. Very strange...
PS I am aware that using hashcode from a string is not a proper or
safe way to generate and id, we will change it later.

It's great news on one side, this means that it has nothing todo with

If someone would take a look, I've uploaded the source to here:

I've tried your suggestion about declaring phone as a private on

Hello Nino,
It seems to be the same issue as i've encountered a week ago.
see thread Order-Items master detail page started at 16 august
Possible Solution in you case:
declare anywhere posible in page
private Phone selectedItem;
in function
protected void onUpdate(AjaxRequestTarget target) {
...
selectedItem = (Phone) phoneA.getObject();
...
}
And than everythingService.findAllStandardFeatures() (or other
function) shoud get access to the
field selectedItem.
Possible you need to create your own new IDataProvider.
Cheers,

I have a page where theres two dropdownchoices and two panels

However it seems as the model of the dropdown are never

And what is the model's role there. i assume you are referring to component.get/setmodel(). this is a default model slot that all components have. its use varies per component. for example label uses the default model slot to get the string it will replace its body with. listview uses it to retrieve a list of items it will use to populate itself. link doesnt use it at all - allowing the user to put their own model into it which is then easy to retrieve inside the onclick event. as your questions get more specific so will the answers :) I have been reading and re-reading the getting started manual, unfortunately it is an extremely incomplete document, so it is of a very limited use, although I appreciate the intention. we depend on our users to make it better.

Re: Component Factory and code against interface
Igor, We are not really trying to make it portable or our own abstraction. The aim would be a subset of the non-ajax Wicket API. In my comfortable ignorance it is a nice way to keep track of dirty components, hide details of ajax/non-ajax and let our tech lead keep firm control over which bits of wicket we use. I'm totally with you that this could turn into a real pain. Container systems like EJB2, Swing etc suggest it can go horribly wrong. igor.vaynberg wrote: the ui layer is generally not portable. if you start building your own abstraction to make it portable you will end up with a pretty big mess because you will be working against whatever framework you are using and eventually that abstraction will turn into a framework itself. -igor On 8/24/07, Sam Hough [EMAIL PROTECTED] wrote: Many thanks Igor, that sounds like a very pragmatic approach.

AjaxFallbackDefaultDataTable... changing sort does not setCurrentPage to 0
I noticed this in the examples:
http://www.wicket-library.com/wicket-examples/repeater/?wicket:bookmarkablePage=%3Aorg.apache.wicket.examples.repeater.AjaxDataTablePage
Changing the sort order does not seem to take you to the first page... I
stepped through the code, and it looks like it should work. Any ideas on how
to get this to work? Here's the relevant snippet from HeadersToolbar:
protected WebMarkupContainer newSortableHeader(String headerId, String
property,
ISortStateLocator locator)
{
return new OrderByBorder(headerId, property, locator)
{
private static final long serialVersionUID = 1L;
protected void onSortChanged()
{
getTable().setCurrentPage(0);
}

DataView and onComponentTag
Hi,
I use a DataView to create a list (ulli). The DataView is used to
render the li-tags. Now I try to add a custom id value to the li tag
if some circumstances are fulfilled:
@Override
protected void onComponentTag( @NotNull ComponentTag tag ) {
super.onComponentTag( tag );
IteratorItem items = getItems();
while ( items.hasNext() ) {
Item item = items.next();
if ( //some magic here with item.getModelObject() ) {
tag.put( id, theIdValue );
}
}
}
But the method onComponentTag in DataView is never called... Any
suggestions?
Thanks,
Johannes Schneider

Re: AjaxFallbackDefaultDataTable... changing sort does not setCurrentPage to 0
I'm not that intrepid so I think I'll just wait until beta3 to get those fixes. The extensions AjaxFallbackDefaultDataTable and related classes are extremely nice, btw. It's allowed me to quickly set up list paging and sorting in a way that would have taken me days using any other web framework. I do have some requests for refinement: 1. It'd be nice to have hard (not runtime generated) CSS classes or ids on HTML elements for components like the NavigatorToolbar, etc. to allow for easy styling via CSS. Something similar to the OddEvenItem concept applied to the page links in the toolbar. I've found a way to style those links, but it could be made easier. 2. Some way to hard-set the width for each column. It's visually distracting to have the column widths change as you page through. This might be done via CSS (maybe give each column a class or id) but this could also be done in Java, for example: ListIColumn columns = new ArrayListIColumn (); columns.add (new SizedPropertyColumn (new Model (ID), id, id, 20%)) ; columns.add (new SizedPropertyColumn (new Model (First Name), firstName, firstName, 40%)) ; columns.add (new SizedPropertyColumn (new Model (Last Name), lastName, lastName, 40%)) ; I'm still a newb, so I'm not sure which way is the wicket way...
