Re: How exactly does RestartResponseAtInterceptPageException work?
I've been thinking about this in the past. Our use case was a post while not logged in. I guess retaining post data is not really a problem. Since the Restart...Exception is under user control, the application would be responsible for not sending megs and megs. Since there is exactly one request pending in this way, I don't see the problem. as for the rest of the problems: redoing posts would go a long way Thomas On Tue, Feb 24, 2009 at 2:03 PM, Martijn Dashorst martijn.dasho...@gmail.com wrote: The problem with returning to the original request is that it can be anything, including a post.

Re: Dynamically changing CSS style attribute
If I have understood Mr. Heptagon right the needle position depends on
server side state. What I would do is look at the source of
AttributeModifier and do something similar, but just take the existing style
attribute and replace the left value (using an regex or such). If
something usable results, you could share the joy (CssStyleModifier.java?)

Re: Wicket at ApacheCon EU'09 in Amsterdam
Unfortunately, those 'idiotic managers' (and I'm not disagreeing with you) hold the purse strings. The move to Apache was a big step towards acceptance by the business types. If you try to sell a new technology with a weird name to your manager, it's not helping that there are just some guys from the internet behind this (let's not argue whether that really matters or not, it's just about the impression it gives). Let's just say this: there are at least two angles to selling a particular technology: the business angle and the technical merits. While the technical merits of Wicket are evangalized, the business case is less promoted. Thomas PS: Just for the record, I'm totally opposed to starting a wicket JSR.

Re: Wicket at ApacheCon EU'09 in Amsterdam
I totally agree that the JSR process is horrid. However, Wicket could really use some more corporate credibility (which a JSR would provide). The problem, I guess is that there are simply no corporate interests behind Wicket that would push the agenda. What wicket need is some evangelism, but I guess all the core people have real jobs. What we need is less talks titled why wicket is cool and more cut your development costs in two with Wicket. From experience, I am totally convinced that you can save 50% off your development costs if you switch to wicket (from just about any other framework), however, I've yet to find a contracting job here in Zürich where wicket is asked for (it's JSF, or even Struts).

Re: setting the value of a radio input field
Server side state as a performance problem is WAY overrated. If you're not
working for Google, it's probably not a problem.
That said: if your Web application has state it has state however much you
may wish it were not so. The only way to remove that state is when you move
it to the client. Then, however, you have to transfer the state to the
server in order to do anything with it, so you're trading memory vs.
bandwith. You may also transfer the state to an external system (which
Wicket does with most pages in the session). Then you're trading memory vs.
time.
If you have a MB of state per session (which is already quite a lot), you
can serve 1024 concurrent sessions per GB of server memory. These days, you
can buy 16GB of memory for just about the price of one day of work from me
(oh, perhaps I really shouldn't tell you that ;-). You'll need to measure
and then decide how important technical statelessness is for you.
State is bad has become an article of faith somehow. There are many
applications where that is simply not true.

Thanks for the tip Thomas! I have it now.
I am really keen to avoid state on the servers, as a design principle. It
forces me to think the web way as much as possible, and when one does,
possibilities start becoming evident. So no I did not do any measurements
there. But these principles are also what brought be to Wicket. I like the
separation of html and logic. I think more needs to be done perhaps to make
stateless programming as easy, or easier than stateful programming, but I
won't pass judgement until I have used Wicket more, and feel like I
understand it properly.
In this case I think it also makes for nice URLs.

item.add(new Label(uri, agt.getWebID().toString()));

});

Re: Page composition question
Hi Uwe,
what is not clear is: are the detail info panels different for each of the 5
customer infos? Then you really would have 15 different html markups for the
5x3 panels? Or are the 3 panel kinds (special, detail, or additiional)
always the same, but appear (or not) for the different customer info types?
If you have 15 different html markups, you'll have to implement 15 different
panels. What's the problem with that? Chuck it in it's own package and
forget it.

but i still cant see how i can define the subPanels.
in facelets, in the parent i would have written:
ui:include name=detailInfo/ otherHTML/ ui:include

then there would be 5 different childs, each one defining the 3
html-snippets:
ui:define name=detailInfohtmlStuff for detailInfo/ui:define
ui:define name=aditionalInfohtmlStuff for additionalInfo/ui:define
.
that means, the parent knows, somebody of his children has defined a
snippet
for detailInfo, and this will be inserted at the ui:include
and so the three snippets can stay within the same file, e.g. in a
SimpleCustomerDetails.xhtml
and in wicket?
i see how i would construct 3 different panels ( newpanel1,2 and 3 in your
example) within the child class extending parentpanel - but every panel i
create in the overwritten methods needs its own html file, doesnt it?
that means, for one of the 5 types of customers i would have to write 3
panels, one for each of the 3 parts:
SimpleCustomerDetailInfoPanel.html, SimpleCustomerSpecialInfoPanel.html,
SimpleCustomerAdditionalInfoPanel.html,
then 3 for VipCustomerDetailInfoPanel.html, and so on, ending up with
15
different html files.
i still dont see the way how i can put e.g.
SimpleCustomerDetailInfoPanel.html, SimpleCustomerSpecialInfoPanel.html and
SimpleCustomerAdditionalInfoPanel.html into one html file (as i can do it
with facelets above), thereby reducing the nr of html files to 5. the 3

dear wicketeers,
i'm facing a problem with page composition where i cant find an elegant
solution; i hope i can explain it comprehensible:
i have a panel named CustomerInfo.
there are 5 types of customers in the application.
most of the CustomerInfo.html is the same for all types of customers -
except three div's:
DetailInfo, SpecialInfo and AdditionalInfo
these two div's contain different html and different components for
each
type of customer;
one way would be to create 15 different panels
(DetailInfoCustomerType1,
DetailInfoCustomerType2, DetailInfoCustomerType3, ,
SpecialInfoCustomerType1, .)
then, in CustomerInfo-panel i would include the right 3 panels
depending
on
the customer type, e.g. (DetailInfoCustomerType1,
SpecialInfoCustomerType1,
AdditionalInfoCustomerType1);
ok, its no good idea to have 15 separate panels, i want to group the 3
html-snippets together (Detail, Special, Additional)
how can i achieve this? as i understood, neither panels, nor fragments
nor
borders can be used for this.
how could a parent container ( CustomerInfo ) fill 3 different areas
(the
3 div's) with 3 different fragments of a child (e.g.
DetailInfoCustomerType2, SpecialInfoCustomerType2,
AdditionalInfoCustomerType2)?
if the 3 different areas were contiguous/adjacent i could use simple
page
inheritance, bc then the parent container pulls out the whole child's
content with wicket:child/ .
in my case i needed sth like wicket:child id=detailInfo/
.much
html/...wicket:child id=specialInfo/ .much
html/...wicket:child id=additionalInfo/ .
where with wicket:child id=xxx/ the parent would only include the
part
of the child with wicket:id xxx

No, what I meant was a single tag link and a list view:

and in code:
List cssFiles= Array.asList(new String[] { base.css, special.css });
add(new ListView(cssList, cssFiles) {
public void populateItem(ListItem item) {
String cssFile= item.getModelObjectAsString();
item.add(new AttributeModifier(href, new AbstractReadOnlyModel() {
public Object getModel() {
return the prefix, don't know where to get it+/+cssFile

});

this is off the top of my head, just to see if we're even on the same page.

Re: What are the consequences on sharing panels between pages?
Well, Wicket has a Session Object. You can create your own subclass and store stuff in there (WebApplication.newSession(...). If you want to share state between pages, it's a natural place to put the state. One question you can ask yourself is: how many instances of that panel would I have? If the answer is: one per user, the state of the panel is session state. So you have multiple copies of the panel, but they all store their state into the session.

Re: What are Behaviors in Wicket?
Behaviours are Objects that can participate in the rendering of a component. They serve to extract behaviour (hence the name) that is common to various components and which cannot be accommodated in the inheritance hierarchy. For example, you can add javascript handlers to many html tags, so you can't really find a nice inheritance hierarchy where a particular subclass tree can have a javascript handler and all others cannot. Instead, you extract the code to a behaviour (for example, there AbstractDefaultAjaxBehaviour to look at) and add it to the components as needed. hth Thomas --- Thomas Mäder www.devotek-it.ch On Sun, Jan 18, 2009 at 10:02 AM, HHB hubaghd...@yahoo.ca wrote: Hey, In easy words, what are Wicket Behaviors? what is their role?

Re: building extensible components
As I understand it, you have a generic container component, which may
contain different subpanels. You do know that Panels can actually have their
own markup and also markup inheritance (?), so you'd end up with three
classes: the main panel (container) and you add an instance of (sub)classes
2 (the static panel) and 3 (the dynamic panel). Favor composition over
inheritance!

Re: passing objects between pages
I have three rules for directly referencing objects from pages
1) It's serializable
2) The valueis not going to change from the time I construct the page
to when I use the object
3) It doesn't matter if I get a copy of the object (because of deserialization).
2 3 can be summarized as the object being a value object

the easiest thing to do is to pass the imodelgroup into the second

in general keeping references to objects is safe for as long as the
objects them selves are valid. the problem with hibernate objects is
that although you have a reference that you can keep forever, the
object's lifecycle is not tied to that reference. the object is tied
to the session whose scope is usually a request, so the object itself
is only valid during the request, which is why you have to use
loadable detachable models.
if you had an object that is not tied to any kind of lifecycle you
could keep a reference indefinetely.
once you start talking about objects that live across pages you run
into another issue. wicket serializes each page individually. that
means if you pass a reference to an object from page A to page B, page
B will end up with a clone and change made to that object inside page
B will not be visible to page A. something to keep in mind. this is
not a problem for multiple references to an object within a page
because serialization will properly keep track of multiple references
to the same object.
clears things up?

hi, i am writing an application, but don't know how best to write it
in wicket. i can see lots of different ways to approach my problem
and would appreciate some direction as to which approach is the most
appropiate. i have read the documentation in the wiki regarding
models and understand the different page constructors but i am
confused about how long the objects are safe to hold on to and which
approach is best.
here is some (pseudo)code for a page i need to write. my situation is
i have one page which shows the details about a Group (collection of
users), which has a link on it to create a new User and add it to
the Group. (the CreateUser page has text boxes to set name ect and
saves to the database on submit) my ViewGroupDetails page:
// first decision = set the Group as a final variable before creating
the link so it is still there in the onClick?
final Group g = (Group)getModelObject();
new Link(adduser) {
public void onclick() {
// or get Group from the page's model only when link clicked?
Group g = (Group)ViewGroup.this.getModelObject();
// second decision = pass the whole Group into the new page constructor?
setResponsePage(new CreateUser(g));
// or make the new User object here and pass it in?
User u = new User();
u.setGroup(g);
setResponsePage(new CreateUser(u));
// or pass in just the group id number?
setResponsePage(new CreateUser(g.getId()));
}
}
so the constructor of my CreateUser page will either take a Group and
will create the User (as above), or take a Group's id number and load
the Group from the database first, or take a User directly. an id
number could be passed in by PageParameters or directly as an integer.
an object could be passed bare or put inside a Model. i am not sure
i am making any sense! i suppose my questions are...
- how 'safe' is it to pass the Group directly to the new page constructor?
- is it safe to create a final reference to an object and rely on that
object being still there and intact by the time the link is clicked?
- is it safe to getModelObject() to get the page's object at any time
in the future?
- i understand that the following is bad: new Label(group.getId())...
better to use a model and load the id when needed... am i falling into
the same trap with the final variables in the code above?

Re: Running a huge wicket site(1m + users)
Sorry, but I just don't see the need for transparent failover in most cases. I don't believe many web applications have unsaved state over more than a few requests. So yes, you lost a server and you have to login again, but so what? It's not like it's going to happen very often to a single user. Sticky sessions for teh win! ;-) And once you remove the need for session state replication the whole argument for client side state just crumbles. Unless you do something like gwt does. But that's really not a web application anymore, but a fat client based on a crappy toolkit (compared to something like Swing or Eclipse RCP). I don't believe Wicket is what you want, then and I don't think Wicket should try to serve that space. Thomas What is this data juggling you talk of? If you use sticky sessions (which is really necessary for any serious web application IMO) there should not be any data juggling. But if you need failover, you need a buddy system, because session sharing across multiple clusters is not that desirable or fast. You eliminate the necessary data-juggling by using an inferior way of failover. Because you need more memory and more processing power and LAN traffic to keep the state synchronized, you simply need more iron to serve your web application. So, you need to scale out to larger clusters earlier. It's cheaper and faster to keep the state at the client. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Structure in Wicket Project
Yeah, but such a policy is complete crap if you'll excuse my french. You can break a wicket applicaion as easily by changing the html files as by changing code. A html change IS a code change.

Re: Wizard and CheckGroup

Hello.

then I go to step 3.
If I back up to step 2, everything remains checked.
However, if I back up again to step 1, then click next to step 2, I lose

In the code for Check, whether or not the checkbox is checked is
determined by this:
if (group.hasRawInput())
{
final String[] input = group.getInputAsArray();
if (input != null)

for (int i = 0; i input.length; i++)

else if (collection.contains(getModelObject()))

When group.hasRawInput() returns false, and we fall through to the else
clause, everything works as expected.
However, when group.hasRawInput() returns true, on the next line
group.getInputAsArray() returns null. This means that the for condition
never gets executed, so my checkboxes don't get checked.
What's the story with hasRawInput()?

Re: patterns for web ui apps. mvc models
Yes, we have a domain model which talks to stateless backend services. The controller, i.e. the application flow and event handling is in the pages. We used to have a different architecture with Spring Webflow (that was in the dark ages of JSF) as the controller. Since we're building a single app, we haven't found it necessary to abstract these control flows out of the pages. Your mileage may vary if you're trying to reuse the workflow across multiple clients. sermon On the topic of patterns I have a favourite quote from a golf istruction book: the best golf swing is one that gets the ball into the hole in the fewest strokes. The patterns you find in books are solutions that worked in the past for other people. Look at them and decide if they work for your particular problem. If you can't decide, you don't understand your problem domain yet. /sermon cheers, Thomas On Wed, Jul 2, 2008 at 9:30 AM, marco m [EMAIL PROTECTED] wrote: Thomas Mäder wrote: Wicket is a framework to write (mostly) statefulweb pages.

OK, to summarize what came previously:
we had a palette control (two parallel listboxes, with push buttons
in between for moving items from one list to the other), and tried to
have a checkbox that would select all - that part worked fine, but
for some reason we couldn't get it so using the buttons to remove
items from the right list would also cause the select all checkbox
to be unchecked. We punted, and used a select all link that didn't
need to be visually updated.
But now we're seeing some kind of related problem... in this form we
have a big CheckGroup -- (previously we had trouble getting the
contents of the CheckGroup to update when they weren't DHTML-visible,
so we redraw the whole panel the checkboxes are on). Individual
subsets of the checkboxes in the overall checkgroup have their own
select all and clear links, along with a written summary of what
is selected inside that checkgroup.
Now, when someone clicks the push button in the pallet control, the
select all links for the checkgroup subsets seem to be updating the
model (since we see the written summary labels update) but the
checkboxes don't check! -- until you click one of the checkboxes in
ANY of the check group subsets, then the select all links can update
the checkboxes as well.
By using labels w/ timestamps, it seems clear that everything is being
redrawn. And even if all the internal logic for the palette control
pushbutton is removed, it's just a AjaxFallbackButton with
setDefaultFormProcessing(false) that does nothing, the select all
links can no longer make the checkboxes show the correct state of
their entry in the cjeckgroup, even as they're redrawn. (Until one is
clicked, at which point the connection is restored)
So what is going on here? Does this symptom seem to point to
something we're doing wrong, or is there some kind of generalized
checkbox updating issue? (since this is KIND of like the previous
problem)

ISO8859-1 (and special chars are not rendered properly in UTF8). But others
web pages are properly rendered (I only have a problem when dealing with
responses)
Have you guys any idea on how to fix it? Do I have to do someting on the
server config?
Thank you vm!

Re: CheckGroup and back Button problem
We seem to have a similar problem with a wizard page. We came across the
following code in Check.onComponentTag(..)
if (group.hasRawInput())
{
final String[] input = group.getInputAsArray();
if (input != null)
{
for (int i = 0; i input.length; i++)
{
if (uuid.equals(input[i]))
{
tag.put(checked, checked);
It looks like the Check component is checking for the existence of raw
input, but then using the input from the current request (via
getInputAsArray()) to render. Sounds fishy! I figure this could be related?

Hi,
I have made a CheckGroup vith a ListView of Check's than works fine, except
that when it is submitted and I'm on the next page and want to go back
through a Wicket Button (not the browsers back button), all the checks are
empty even thouch the model behind still contains the selected obejcts.
Here
is the example code of the first page:
public HomePage() {
Order order = ((WicketSession) (Session.get())).getOrder();
if (order.getDigitalPackets() == null)
order.setDigitalPackets(new ArrayListProduct());
System.err.println(LIST1 = + order.getDigitalPackets());
Form form = new DigitalOrderForm(digitalOrderForm);
form.setModel(new CompoundPropertyModel(order));
add(form);
ListProduct allProducts = new ArrayListProduct();
for (int i = 0; i 10; i++) {
Product p = new Product();
p.setProductKey(i + );
p.setTotalPrice(new BigDecimal(100 + i));
p.setProductName(Product + i);
allProducts.add(p);
}
CheckGroup group = new CheckGroup(digitalPackets);
form.add(group);
ListView products = new ListView(products, allProducts) {
protected void populateItem(ListItem item) {
item.add(new Check(check,
item.getModel()).setEscapeModelStrings(false));
item.add(new Label(productName, new
PropertyModel(item.getModel(), productName)));
item.add(new Label(totalPrice, new
PropertyModel(item.getModel(), totalPrice)));
}
};
group.add(products.setReuseItems(true));
}
class DigitalOrderForm extends Form {
DigitalOrderForm(String s) {
super(s);
}
protected void onSubmit() {
Order order = (Order) getModelObject();
System.err.println(LIST2 = +
order.getDigitalPackets());
setResponsePage(PageTwo.class);
}
}
The second page is just a back button like this:
public PageTwo() {
add(new Button(back) {
public void onSubmit() {
setResponsePage(HomePage.class);
}
});
}
Anybody knows how to get the selected objects shown when you go back like
that ?

Re: Problem with german error messages in feedback panel
Hi, properties files are ALWAYS encoded with ISO 8859-1 encoding. Check the javadoc for java.util.Properties for more info Thomas On Sun, Apr 27, 2008 at 11:35 AM, greeklinux [EMAIL PROTECTED] wrote: Hello, I have problems with german umlauts in a feedback panel.
