Re: onmouseover image
Have a look at AjaxEventBehavior. You can either combine this with an Image component or add an AttributeModifier and manually tweak the img's src attribute. Alastair 2008/9/19 Tim Squires [EMAIL PROTECTED] Hi All, Before I go and write my own component to change the src of an img onouseover, I just wanted to make sure that there is no standard component. I don't want to re-invent the wheel. Is there a standard component for changing the Image or ImageButton image onmouseover?

Re: Discussion on Wicket Interface Speed-Up
Hmmm. As you say, there's no easy one-size-fits-all.
There is an obvious improvement you could make, though. All JS/CSS
contributions initially rendered on the home page could be batched up. This
will typically provide the biggest improvement anyway. You could then keep a
reference to this batch, and use it instead of individually including any of
these constituent contributions elsewhere.
This would also give fairly intuitive behaviour - if you want to pre-load
your JS/CSS in a single batch, just add the headercontributors to your home
page, and Wicket will figure it out.
I've long hated having to specify the component class in header
contributors, as 99% of the time the resources live in the same package (or
in a subpackage) as the component they belong to.
I'd even go so far as to remove the need for HeaderContributor code entirely
in 80% of the cases.
Wicket could automatically pick up css and js files that are named the same
as your component.
MyComponent.java
MyComponent.html
MyComponent.properties
So why not:
MyComponent.css
MyComponent.js
?
Heck, you could even include i18n for dealing with language-specific layout
issues:
MyComponent_jp.css

I see your point, essentially we have 1 (relativity large) bundle file per
page, and if you have 5 pages which use jquery, tinymce and ajax then you
are worse off, since the normal way you would have already cached the 3
individual files (this is what you meant right?)
Maybe there is some way to automatically work out the best bundles to
create
depending on usage, so dont create bundles based on page, but based on
contents?
I think the real answer is that everyones usage is different and what is
good for one system isn't good for another.

It's not the pages that have these files. Let's say I have a page that
uses jquery and a textfield with a button that toggles tinymce.
If we do what you say then there are two possible files: jquery and
jquery+tinymce.
Than let's say I add Ajax to the page, now there are 6 possibilities
depending on which components are currently on the page.
IMHO much cheaper to just cache jquery, tinymce, wicket-Ajax
individually.

im not sure we could help in the cases where you have dynamic header

But i dont see how this would result in many many large files. you
would
have a single file for the static stuff, and then each dynamic one would
have its own file (assuming not specified up front). This would still
bring
down the total number.
eg a page has 6 static js and 2 dynamic js which would get turned into 1
static js and the same 2 dynamic js.
cases where a component and resulting header contributers are added via
ajax
wouldnt be important for the initial page load speed anyway, as they are
added after the page has loaded.

The problem of breaking encapsulation:
I did some work on this problem on my own a few months ago, my
solution
was
to use a header contrib manager, and instead of adding files with a
header
contributer i add them to the manager, then get a single contributer
per
page from the manger.
for example in a panel you would do
@Override
protected void onBeforeRender() {
super.onBeforeRender();
ResourceReference rr = new
ResourceReference(getClass(),
test.js);
WicketApplication.get().getHcm().add(rr,
getPage().getClass());
}
See how it uses getPage().getClass(), so the manager knows which class
the
panel is being added into
then in the main page class
@Override
protected void onBeforeRender() {
super.onBeforeRender();
add(WicketApplication.get().getHcm().getHeaderContributor(getClass()));
}
since the manager knows all of the resources added for the page at
this
point, it is easy to compress them all together and serve a single
file,
and
you dont have to list the files up front.
What do you think of this idea?
My code is here:

Re: Implement LabeledLink and ImageLink components - what is the most elegant way?
For something like this, you probably want to avoid having markup files at all.
Seeing as you want something that is both a Link and a Label, a good
starting point might be to look at the source code for both.
You should be able to extend the Link class, and override
onComponentTagBody() in much the same way that Label does.
Alastair
2008/8/26 Michael Sparer [EMAIL PROTECTED]:
yes, you're right, that's a very common scenario :-)
we use an AbstractLinkPanel as base-class, markup goes like this:
[wicket:panel]
[a href=# wicket:id=link][span wicket:id=linkTitle]Label[/span][/a]
[/wicket:panel]
and then in java pass the label via constructor. and provide an abstract
method to return the link ... and add the link in the onbeforerender method
... e.g.
new AbstractLinkPanel(id, new ResourceModel(label)) {
protected AbstractLink getLink(id) {
return new Link(id) {
// snip
}
}
}
for bookmarkablepagelinks with labels we just subclass AbstractLinkPanel,
return a BookmarkablePageLink there and pass the params _and_ the title in
the constructor. e.g.
new BookmarkablePageLinkPanel(id, new ResourceModel(label),
FooPage.class, FooPage.getParams(pojo));
well that's our approach, works pretty well ... but, as you said, would be
great to have out-of-the box. but maybe that's already too specific to be in
the wicket-core, as we as wicket-users are expected to implement exactly
such components that fit our needs ... would be interesting to hear a
developer's opinion about that.

Michael

Hi everybody,
Perhaps I am just temporarily dumb, but I do not seem to be able to find
an elegant solution for the following use case.
I constantly create Links with just a single Label or a single Image in
it. It would be convenient for me to create a LabeledLink or ImageLink,
taking a content string/model or URL as param. (btw: I would LOVE to see
something like this by default in wicket)
My first idea was to inherit from BookmarkablePageLink and use
wicket:extend to add markup - this does not work because markup file is
ignored. This is understandable because wicket probably would not know
where exactly to place the additional markup, because BPL does not have a
wicket:child tag.
So what is the best way to do this? I thought about inheriting from Panel,
adding link and label, setting the panel's setRenderBodyOnly to true (to
avoid useless markup) and override both the panel's and the link's
onComponentTag method in order to adopt the original tag's attributes
nevertheless... would work, but is definitely far away from being
elegant...
There is no way to inherit from a component and add markup when there's no
wicket:child, right?
Thanks for inspiration :)

Re: Wicket Image - Java Image
Sounds to me like you're somewhat confused. ;-)
Load the image from the classpath into a bufferedimage as you would
outside of Wicket (Foo.class.getResourceAsStream() or whatever it is).
Draw text, etc. on it as you see fit.
Display it with Wicket if you want to via a BufferedDynamicImageResource.
If you don't want the overhead of storing the image in the session,
use a RenderedDynamicImageResource and load the classpath resource
image in the render method.
These things are always a trade-off between having to do the graphics
drawing operations every time you render the page, and keeping the
image hanging around which takes up space. Your choice.

Re: Comparing JSF and Wicket
2008/8/7 nlif [EMAIL PROTECTED]: While it is very good to know that it's relatively easy to develop Wicket components, bear in mind that management (at least mine) is more easily convinced when presented with a wide selection of 3rd party component libraries, since that provides an alternative to allocating time and resources of our own developers. Thus, for them, the issue is decided more an economical merits, then on its design/architectural ones. Your company should concentrate on what it does as its core competency as that will bring you the most value for time invested. Based on past experience with many companies, I can most glibly and universally sum this up as: Don't write a ticketing system unless you sell ticketing systems. You are presumably building web apps because you think you're quite good at it (or perhaps will be), and you're worried about working at the right level of abstraction to achieve good productivity. You're concerned that Wicket might be at too low a level of abstraction compared to JSF, because JSF has a plentiful array of off-the-shelf components that you think will let you work at a higher level of abstraction, and therefore you'll be more productive with it. It's a nice idea. It certainly looks tempting. Unfortunately, it just isn't the case. Why is that? Go and read Joel Spolsky's article on leaky abstractions[1]. Right now: http://www.joelonsoftware.com/articles/LeakyAbstractions.html Good to have you back. Here are just a few reasons why pre-built components in JSF are not the answer. At some point, normally just after you've completely wedded yourself to a component, someone important will want you to change something that on the surface should be trivial. At this point, you will need to unpick the entire component and figure out how it works, and change it. This will be hard. You will probably introduce bugs. Unless it's a component with a lot of distinct regions of complexity, it will probably be so hard that you may as well have developed the code yourself from scratch (in either JSF or Wicket). Reading code is harder than writing it. Anything remotely complex will need to you restyle it all to make it fit in with the rest of your web pages. This will likely be painful unless the component developer has a clue. Nine times out of ten, it will take you so long to find the component you need, test it works in your environment, make sure it does what you need, make sure it probably does what you might need, discover it doesn't, find another component that does, sort out the licensing, file a purchase order for it, etc. etc. that you could have developed something in Wicket that did exactly what you wanted in half the time. It seems to be the case that if the component is sufficiently complex that you think you will save time/money by buying it in rather than building it, it doesn't do what you want. There are only about five or six truly universal components that are applicable to almost everyone. These are: tree, tree but in a table, sortable paginated data-driven list, date picker, modal pop-up window, AJAX auto-complete drop-down. I can't think of any others, but there might be a couple. Wicket has all of these. Which you'd know if you'd bothered to look at the examples, which are live and prominently linked from the site. Sorry to sound harsh, but how much web development are you going to do? Hmmm? Eight hours' worth? Go use PHP or JSP or DHTML or whatever. Your use case isn't complex enough to be having this discussion. Eight months' worth? What? You're going to make a decision without investing a day in each option at least? Are you crazy? How many Wicket components are there, and how mature are there? Are there tables with sorting, filtering, scrolling, paging etc.? Are there tree-controls with all the typical tree-functions? Is there Ajax support, as well automatic fallback for non-javascript browsers (and what about comet)?

Re: Help!! TextField in ListView = NULL
Have you done any web development before using Wicket?
If so, you should be able to solve this problem by asking yourself the
following questions:
What happens if you click a link on a web page?
Do you think the browser sends the data in a text field on the page to
the server if you click a link?
What about if you put the input tag in a form and click a link?
What about if you put the input tag in a form and click a submit button?
In short, I'd suggest thinking a little more about the fundamentals
before playing around with user input in listviews. Have a look at the
examples.

P.S. There are ways to do what you're trying to do without needing to
put things in a form, etc., but they involve AJAX and therefore
probably aren't the best solution for whatever it is you're trying to
do.

Re: RelativePathPrefixHandler and form action attributes
2008/7/18 Brad Fritz [EMAIL PROTECTED]: I am trying to rewrite an HTML form action attribute (for a non-Wicket form) inside a Wicket Panel and could use some help. While converting a large webapp to Wicket, I created a Panel to wrap a search form. The form processing is not handled by Wicket yet. So in my SearchPanel.html, I have something like this: wicket:panel form method=get action=search.do [..] /form a href=search.doAdvanced Search/a /wicket:panel The Advanced Search href is automatically prefixed with the correct number of ../ strings by RelativePathPrefixHandler, but the form action is not rewritten. Is adding a new IMarkupFilter (based on RelativePathPrefixHandler) to handle the action attribute rewriting a good option? Or is there a better way? You could make the form into a wicket component (use a WebMarkupContainer), and then add an AttributeModifier which does what you want from code. Any ideas on how to best handle this scenario would be much appreciated. Thanks! However, this seems like a bug to me. Obviously non-Wicket form tags should have their action attributes rewritten like everything else does.

Re: Multiple Layouts using Inheritance
It doesn't sound like you're trying to inherit anything, not in the object-oriented sense of the term. Instead you just want to use different markup for a page dependent on some criteria. Wicket already does this for localised versions of a page. HomePage.html HomePage_de.html HomePage_fr.html etc. Wicket will select the variation here by default based on the locale of your session (picked up from the browser's language headers). However, you can trivially override how this works by overriding the getVariation() method in your WebPage subclass and returning something else. Best regards, Alastair 2008/6/11 Kram.V [EMAIL PROTECTED]: In Wicket is it possible to inherit from multiple layouts? What we are trying to do is introduce different skins for the same application (We could control all of this in CSS and forget about it, but want to try this first) Each skin is a different Layout Page/Class in Wicket, how can we switch the inheriting Page/Class's layout. For instance: Class Skin1 extends WebPage Class Skin2 extends WebPage abstract BasePage() - Don't know how to design this one yet! MyPage extends BasePage and MyPage should use either Skin1 or Skin2 based on some criteria inside of BasePage. Is this even doable ?

Reminder: London Wicket event at Google UK on Wednesday
Hi folks, Quick reminder that we're hosting another London Wicket event *this Wednesday* at Google's London office. It's looking like it might well be the best one to date, with a bunch of really interesting stuff and some cracking talks. Lots of cool stuff is lined up: - *Richard Wilkinson http://www.richard-wilkinson.co.uk/* on Wicket Google Maps controls and mash-ups. - *Wille Faler http://faler.wordpress.com/* talking how to get the OpenSessionInView enterprise pattern working in your Wicket app. - *Cemal Bayramoglu http://jweekend.co.uk* demonstrating how to tame your drop downs and make them behave just so. - *Al Maw http://herebebeasties.com* walking you through an entire crazy-cool AJAX-heavy app, using some of the components previously created for past London Wicket talks. As usual there will be: - Lots of pizza. - A visit to the pub afterwards. - People to help you out with any thorny Wicket issues you may be having (bring your code!). In short, it's shaping up to be rather ace. You should come. *You'll need to sign up, which you can do here: * http://jweekend.co.uk/dev/LWUGReg/ A reminder: talks and code from previous events available here: http://londonwicket.org Hope to see you there!

Re: users, please give us your opinion: what is your take on generics with Wicket
I think you miss John's point, which is that when you use a CompoundPropertyModel for a component, all its children typically do not reference models explicitly. Thus you typically use an explicit model on 30% of your components if you have a form-heavy web-app; the other components use the implicit model provided by the parent's CompoundPropertyModel.

Eeek. Not to be rude, but I really can't read that at all.
Some well-named intermediate variables and a comment might not go amiss.
Your panel is relying on being added to the home page.
This is bad and wrong.
Why don't you pass the calendar into the constructor of the panel?
That would be an awful lot simpler and result in nice readable, correct
code.

Re: Render body only
Yeah. It's a bit nasty, but there's not really any other way to have both the flexibility and the convenience, unless you have some brilliant other idea?

This is good when the value of the property can change over the lifetime of the component, or when the value of the property is not known until the component is attached to its parent.

Re: Tomcat dying with Wicket 1.3.2 (Windows / JDK 1.5.0_10)
You can use as many anonymous inner classes as you like. I have them coming out of my ears, personally. It's very odd for tomcat to die with no output. There will be output somewhere. Check logs/catalina.out and also logs/localhost*. If the JVM dies, it will hotspot or even segfault and log that, at least. If you have gradually increasing memory footprint then this should be pretty easy to track down with a profiler. Make sure you run Tomcat with a sensible amount of permanent generation space (128M+). Regards, Alastair On Thu, Apr 3, 2008 at 6:43 AM, Martijn Dashorst [EMAIL PROTECTED] wrote: There are commandline options for the jvm to dump on OOM. Anyway, doesn't the log file give any insight into what is happening in your application? Did you (or your sysadmin) disable logging for Wicket? You can also run external tools to see what is happening inside your JVM without blocking the app. e.g. use jmap -histo to see how many objects are alive at a particular moment. The top 10 is always interesting. In my case I found a memory leak in the diskpagestore when exceptions occurred during writing to disk. This is solved in 1.3.3 (which is just days away from an official release, try it!) jstat -gc -h50 pid 1000 will log the garbage collector statistics every second. Martijn On 4/3/08, Jeremy Thomerson [EMAIL PROTECTED] wrote: I upgraded my biggest production app from 1.2.6 to 1.3 last week. I have had several apps running on 1.3 since it was in beta with no problems - running for months without restarting. This app receives more traffic than any of the rest. We have a decent server, and I had always allowed Tomcat 1.5GB of RAM to operate with. It never had a problem doing so, and I didn't have OutOfMemory errors. Now, after the upgrade to 1.3.2, I am having all sorts of trouble. It ran for several days without a problem, but then started dying a couple times a day. Today it has died four times. Here are a couple odd things about this: - On 1.2.6, I never had a problem with stability - the app would run weeks between restarts (I restart once per deployment, anywhere from once a week to at the longest about two months between deploy / restart). - Tomcat DIES instead of hanging when there is a problem. Always before, if I had an issue, Tomcat would hang, and there would be OOM in the logs. Now, when it crashes, and I sign in to the server, Tomcat is not running at all. There is nothing in the Tomcat logs that says anything, or in eventvwr. - I do not get OutOfMemory error in any logs, whereas I have always seen it in the logs before when I had an issue with other apps. I am running Tomcat as a service on Windows, but it writes stdout / stderr to logs, and I write my logging out to logs, and none of these logs include ANY errors - they all just suddenly stop at the time of the crash. My money is that it is an OOM error caused by somewhere that I am doing something I shouldn't be with Wicket. There's no logs that even say it is an OOM, but the memory continues to increase linearly over time as the app runs now (it didn't do that before). My first guess is my previous proliferate use of anonymous inner classes. I have seen in the email threads that this shouldn't be done in 1.3. Of course, the real answer is that I'm going to be digging through profilers and lines of code until I get this fixed. My question, though, is from the Wicket devs / experienced users - where should I look first? Is there something that changed between 1.2.6 and 1.3 that might have caused me problems where 1.2.6 was more forgiving? I'm running the app with JProbe right now so that I can get a snapshot of memory when it gets really high.

I cannot pass the list of DataTransferObject until the user enters
search

Is there any better way to do this?

Re: ListView with a Set instead of a List
// Simply:
IModel listModel = new AbstractReadOnlyModel() {
public Object getObject() {
return new ArrayList(mySet);
}
};
// Or if you want to wrap a property model (not that this is as nice):
IModel listModel = new PropertyModel(bean, mySetHere) {
public Object getObject() {
return new ArrayList((Set)super.getObject());
}
};
// Then just:
new ListView(foo, listModel) {
public void populateItem(ListItem item) {
// ...
}
};
In your original code you go:
return Collections.unmodifiableSet(new
LinkedHashSetFunctionSetting(m_functionSettings))
Which seems rather complex. If you're going to give the user a copy, why do
you care if they modify it? If you're building this all just for Wicket,
then you're quite mad and should figure out a way to make this much simpler.
You ought to think about your API contracts. If you're relying on your Set
being sorted in order to have it make sense in Wicket (which it seems you
are, given you've implemented this using a LinkedHashSet internally) then
you should expose it as a SortedSet through the API.
You could then either use a RepeatingView to display the items (which would
be trivial) or write a little model wrapping class that converts a List to a
SortedSet and back again. If you're only going to use the set as a read-only
data source for Wicket, and you're going to update the underlying set object
in your other code (e.g. onClick handlers) then you can get away with just
wrapping it as in my provided code.

Re: Calling a JS function from onNodeLinkClicked in a Tree?
This isn't as easy to tweak as it could be, I'm afraid. :-(
You're better off using target on the href than doing this with JavaScript,
I'd have thought.
That said, most people think that choosing to open a new window or not is
pretty evil - the user has the option to do this if they want to, it breaks
the expected functionality of the back button, etc. etc.
I'd probably extend BaseTree in core and write my own little Panel which
just displays a link, which obviously you can tweak as you like. If you want
to pop things up using JavaScript, you can use Link#setPopupSettings(...) to
achieve this nicely.

Hi all,
I'm using a Tree for navigation and I have a need to load an external page
in a new window when a link is clicked in the tree. I was hoping to put
something in the onNodeLinkClicked function for my tree that could
create/call a JS function to load the URL in a new window as required.
This
does not need to be done for the entire tree structure, so I need to be
able
to set up this functionality for specified nodes only. Is there a way to
do
this?
I have read the JS related article on the wiki (
http://cwiki.apache.org/WICKET/calling-javascript-function-on-wicket-components-onclick.html
http://cwiki.apache.org/WICKET/calling-javascript-function-on-wicket-components-onclick.html
), but I don't see how to add this to only a few nodes in a tree.
Here's my tree definition:
private Tree getTree()
{
final Tree linkTree = new Tree(navTree, createNavigationTreeModel())
{
private static final long serialVersionUID = -4646756742893751770L;
@Override
protected void onNodeLinkClicked(AjaxRequestTarget target, TreeNode
node)
{
// If this is a MenuItem, reload content.
if (((DefaultMutableTreeNode) node).getUserObject() instanceof
MenuItem)
{
MenuItem menuItem = (MenuItem) ((DefaultMutableTreeNode)
node).getUserObject();
Panel contentPanel = menuItem.getContent();
contentPanel.setOutputMarkupId(true);
MenuPanel.this.getParent().replace(contentPanel);
target.addComponent(contentPanel);
}
else if (((DefaultMutableTreeNode) node).getUserObject() instanceof
Menu)
{
Menu menu = (Menu) ((DefaultMutableTreeNode) node).getUserObject();
// Use Javascript to open new window? Get URL from menu object.
}
getTreeState().selectNode(node, true);
super.onNodeLinkClicked(target, node);
}
};
linkTree.setRootLess(true);
linkTree.setOutputMarkupId(true);
return linkTree;
}
The if(MenuItem) replace portion works great, it's the else if(Menu) part
that has me stuck. Thanks in advance for any suggestions or comments.

Re: export excel file via an OutputStream
I think he makes a valid point, personally. People do want to do this sort
of thing quite frequently. It wouldn't kill us to implement an
OutputStreamLink that looked like this:
add(new StreamingLink(link) {
public String getFileName() {
return download.xls;
}
public String getMimeType() {
return application/vnd.excel; // Or whatever it is.
}
public void writeToOutputStream(OutputStream outputStream) {
excelGenerator.writeOutput(outputStream);
}
});
I don't think the current API here is very pleasant or obvious to use.

Re: Advance RadioChoice Examples
You have to use the constructor that takes an IChoiceRenderer, same as any other AbstractChoice component like a DropDownChoice.

Re: refreshing page
Really need some code to see exactly what you're doing wrong here.
Wicket uses models to bind your view components to your actual data.
Assuming you're using a ListView, you'll need something like:
IModel model = new AbstractReadOnlyModel() {
public Object getObject() {
// Database query here, e.g:
ListProduct products = productDao.findByStatus(Status.LIVE);
return products;
}
};
add(new ListView(foo, model) {
void populateItem(ListItem item) {
Product product = (Product)item.getModelObject();
item.add(new Label(name, product.getName()));
}
});
This model lets you pull stuff on-demand out of your database every time the
page is rendered. The ListView by default will recreate its entire set of
items every page render. You can change this behaviour with
#setReuseItems(true), but you probably don't want to for this. ;-)
Make sense?

Al

Re: RequestCycle exception explanation
OK, but the reason is always the same - the user will be trying to click on something that doesn't exist any more. I can't quite remember how our page versioning works for this (Eelco? Igor?) but it might be possible that users are clicking the same link twice and that the first click removes the component they've clicked on from the hierarchy, causing the second click to fail?

Google hosting next London Apache Wicket User Group meet on Wednesday April 2nd.
Hi folks, Building on the success of the previous Apache Wicket User Group meet last month, Google UK has generously decided to host the next one. This time, the fun and games will happen on *April 2nd*, starting at *6:30pm *. To sign up and for more details (links to a map, etc.) please go to: * http://jweekend.co.uk/dev/LWUGReg/* We'd love to get more of you involved in this event, so here are some ideas to get you started: - We'd love to have some short talks or stories about how you're using Wicket. One minute or twenty, it's up to you. - Similar to last time, we will have a couple of 20 minutes presentations covering topics of interest in a fairly in-depth manner. If you'd like to present something like this, please shout. (Last time I talked about creating a really generic reusable AJAX drag-and-drop list editor and Ian Godman talked about his security framework.) - Bring your coding problems! There will be quite a few knowledgeable Wicket folk there, so you can get them to help you debug things for free (or the promise of a pint afterwards). - Based on the feedback we've had, there will be more breaks and time for networking than last time. Come! Bring your laptop! We have wi-fi, projectors, and all the other things you might need and expect, like beach balls and a plentiful supply of pizza. Hope to see many of you there!

Re: n^2 loop in MarkupContainer?
The children field is private to Component, so I figure we could make children transient, double the array size each time each time we add components if it's not big enough (like ArrayList does), and then in detach() we could copy the children over to a non-transient variable and null out the transient field. We should do some cleverness to avoid the copy if things haven't changed between attach()/detach().

Icy wrote: *** What is the best practise to not instanciate page aggregating panels all the time? *** This isn't really a Wicket question. Your page is slow because doing database/remote operations is slow.

You need to break those operations out into a service layer that can cache the results, then use that service layer in your constructor.

So, you want something similar to onclick in an AjaxLink...
Let's see, it's similar to AjaxLink...
Oh, I know... Why don't we go and see how AjaxLink works?

Hmmm, that looks pretty compact and simple. Oh, look; all the work is
done in the constructor, where we add something called an
AjaxEventBehavior for the onclick javascript event.
It looks like onClick() for the AjaxLink is called by the onEvent()
function in that behavior. Hmmm... I wonder how that works?
ctrl+clicks on AjaxEventBehavior
Oh, look, in onComponentTag() we put an attribute into the HTML tag. The
name is pulled from the event variable (so onclick for the AjaxLink)
and the value of the attribute is the return value from getEventHandler().
I wonder where getEventHandler() comes from and what it does?
goes and looks
Ah, it just calls getCallbackScript().
That's not in this class - it must be in the super class.

Oh, yes, look - it's in AbstractDefaultAjaxBehavior. Maybe I can just
use that?
AbstractDefaultAjaxBehavior behavior = new AbstractDefaultAjaxBehavior() {
protected void respond(AjaxRequestTarget target) {
// Do stuff here.
}
};
Then in my Javascript for the page I can just invoke the JavaScript
generated by behavior.getCallbackScript();
Yes, mmm, that seems to work.
That wasn't so hard to work out, now, was it?

Re: Screen resolution and diffrent markup files
Artur W. wrote:
Is is possible to create different markup files (for the same page) depends
on user screen resolution?
This is quite easy, actually.
Create an abstract ResolutionDependentPage extends WebPage which your
pages will extend.
Add this method:
@Override
public String getVariation() {
WebClientInfo info =
(WebClientInfo)getRequestCycle().getClientInfo();
ClientProperties p = info.getClientProperties();
// Defaults to -1 if not available (JS disabled).
int width = p.getScreenWidth();
String size;
if (width 1024) {
size = small;
}
else if (width 1280) {
size = medium;
}
else {
size = large;
}
return super.getVariation() + _ + size;
}
That should let you localize things properly, too, e.g:
HomePage_de_big.html
Note that in order to gather the extended browser info stuff like screen
resolution, you need to go:
getRequestCycleSettings().setGatherExtendedBrowserInfo(true);
...in your application's init() method.
Should work, maybe. ;-)
BTW, note that in the example above, I'm not using exact resolutions.
This is because I really don't think you want to do that - there are an
awful lot of possible resolutions, what with people using widescreen
laptop displays. If you include the randomly-sized VMware/Parallels
desktops you can have, the possibilities are effectively infinite. ;-)

You need a better understanding of why page instances are created in Wicket and why. It's important to realise that Wicket doesn't currently have a PageFactory type thing - instead we effectively just go getHomePage.newInstance() when the user lands on the home page URL. Therefore, at the moment, you cannot get Spring to manage all your pages for you. What's more, you probably don't want to, as this would introduce serialization issues with things like DAO beans, which is specifically why wicket-ioc and wicket-spring/wicket-spring-annot exist in the first place. Pages are not singletons - they are specific instances created due to hitting a bookmarkable URL or whatever.

What do other people use (no, not the spring crowd ;) ? One EntityManager per Request seems to be the obvious idea and a guice Provider may help with that. Does anyone have serious experiences with that or other suggestions? Subclass WebRequestCycle, and construct it with an EntityManager. In onBeginRequest(), create a transaction, storing it in a private variable. In onEndRequest(), commit the transaction if it hasn't already been rolled back and clean up the EntityManager. In onRuntimeException(...), rollback the transaction and then return super.onRuntimeException(...). You'll need to inject a ProviderEntityManager into your WebApplication subclass such that you can call .get() on it when you make your custom WebRequestCycle. You'll need to configure that provider in a Guice module somewhere, obviously. You should be able to figure that out. ;-) How do you inject things into your WebApplication? Well, you can use the new GuiceWebApplicationFactory, which unfortunately didn't quite make it into 1.3.0-rc1 but is in trunk. However, you can copy that class from trunk and use it in your own project quite happily - it has no extra dependencies. If you need to integrate with your container-managed JTA transactions you'll need something a little different (the container may well start and commit the tx for you), but the principle is roughly the same.

That, in fact, is most of the reason why we're using relative URLs in 1.3. Murat: I have this working perfectly fine on lots of hosts. What version of Apache do you have? Don't forget to add the ProxyPassReverseCookiePath directive in, or you may have issues with sessions. It sounds to me like your Apache isn't honouring the ProxyPassReverse directive. Explanation === When a request comes in to your Apache, it forwards it on using the ProxyPass configuration to your tomcat/jetty/whatever. If you're using a context path other than the root one, then that request looks like this: http://appserver:8080/contextPath/filterMapping/pageName or http://appserver:8080/contextPath/filterMapping/?wicket:interface=[...] etc. The appserver doesn't know anything about your proxy, so when it does a 302 redirect, it will do it to somewhere like this: /contextPath/filterMapping/?wicket:interface=[...] Apache is then responsible for converting the URL in the 302 redirect into the proxied-version. It does this using the ProxyPassReverse config. In the above example, it'll need to rewrite /contextPath/ to / ProxyPassReverseCookiePath is used to do the same thing with any cookies in the response. Cookies have a URL/domain, and your Tomcat will set them at /contextPath/, so that also needs rewriting to / otherwise the browser won't send them on the next request, which means your session won't work. Murat: My suggestion to you is to strip out all the other config from your VirtualHost (all the RewriteEngine stuff, etc.) and first get it working using the basic set-up on the wiki-page.

Suggestions (not really thought through well, so apologies if they seem
silly):
- InjectorHolder.getInjectors() returns any/all injector references
- InjectorHolder.getInjector(_some enum / constant)
If you're planning supporting multiple ConfigurableInjectors within the same
wicket app simultaneously, changing InjectorHolder to a multi-valued object
would make the most sense. Although I agree this gets a bit away from the
simplicity of the existing model.
Yeah. I think maybe:
public static ConfigurableInjector getInjector() {
return getInjectors(null);
}
public static ConfigurableInjector getInjector() {
if (type == null injectors.size() 1) {
throw new IllegalArgumentException(
Have more than one Injector available
);
}
}
...sort of thing, would make some sense. That way we won't break
existing people's code. I'll have a look into this ahead of the RC2 release.

This is because you need to provide a second constructor parameter of

Well, given the javadoc I told you to read for the second parameter there, no. ;-) It doesn't make much difference which you use. AbstractBehavior is more direct and concise. AttributeModifier is named such that people will find it. I tend to use the former for what you're doing, and the latter if I already have a model kicking around. There's also a SimpleAttributeModifier if you have a simple String, and an AttributeAppender if you wish to mess with what's currently there.

Well, obviously if you want to handle clicking on things without
Javascript then whatever it is needs to be a standard Link.
You can abandon tables and do something like this:
div wicket:id=listView
a wicket:id=link class=rowLink
span wicket:id=name/span
span wicket:id=summary/span
/a
/div
.rowLink {
display: block;
}
.rowLink span {
width: 50%;
display: block;
float: left;
}
==
Or maybe you could do this with CSS, but it'd break the accessibility
totally:
table class=clickableRows
tr
tda class=rowLink wicket:id=link/a/td
tdName/td
tdSummary/td
/tr
/table
.clickableRows tr {
position: relative;
}
.clickableRows a.rowLink {
display: block;
position: absolute;
z-index: 1000;
top: 0;
right: 0;
bottom: 0;
left: 0;
}
Although the browsers may well not know what to make of that, IE in
particular. No idea if it will even vaguely work, but it might give you
ideas. ;-)

You'd typically use the model so you have something to get at in the
onClick().
Of course, if you don't care about how much state is in your session,
you can just make whatever it is final so you can use it in there anyway.
If you want to use the model for the text of the link instead, then you
could write a class like this:
public abstract class TextLink extends Link {
public TextLink(String id, IModel model) {
super(id, model);
}
protected void onComponentTagBody(final MarkupStream markupStream,
final ComponentTag openTag)
{
replaceComponentTagBody(
markupStream, openTag, getModelObjectAsString()
);
}

If you want enabled/disabled to work properly, you'll need to copy the
relevant bits out of AbstractLink#onComponentTagBody(...)

auron wrote: Sorry to be the wicket newbie, but I was wondering if you guys could help me to understand how Links work. I understand that when you do Link(SomePage.class), it calls the zero param constructor of SomePage, and when you do Link(new SomePage(someParams)) you can call other constructors, but besides this, what are the other differences? I assume you're talking about PageLink not Link? new PageLink(id, SomePage.class) will generate a URL which will construct a new page when you click on it. new PageLink(id, new SomePage()) obviously creates a SomePage instance right then and there. The page instance is stored in the session and dug out if the user clicks on the link. You should obviously try to create links which create new pages when you click on them, not when you construct the link (i.e. the former). For this reason, in Wicket 1.3 we've deprecated the second form as this seemed to confuse people. Instead, use a normal Link and call setResponsePage() in the onClick(). At least, then it'll be obvious what you're doing and encourage people to only construct their new pages within a click handler, rather than within the constructor for the original page.

Re: Jira issue moved to the list: constructors and init of components
Brill Pappin wrote:
Moving to the list as suggested by Gwyn.
From Jira issue:
https://issues.apache.org/jira/browse/WICKET-1108
Maybe I wasn't clear on what my problem with it was.
1) doing any extensive amount of work in a constructor is an anti-pattern
AFAIK.
Blindly declaring things anti-patterns with no real rationale is dangerous.
Constructors are designed to ensure that your object is completely
initialised and ready for use. If your page doesn't have all its
components added, then it's not initialised and ready for use.
Therefore, I think putting all that logic in there is a perfectly valid
place for it.
There's nothing to stop you making your constructor call methods to
initialise things that people can then override. Generally you won't
want to make/let people completely override everything, so you need to
put some thought into this. If you do want this, then just use a blank
super constructor and you're done (you can then sit back and watch your
users hate you).
2) If the API is designed so that I am expected to build a complex component
in it's constructor then I should be able to override any of the
constructors and expect it to be called.
But, err, you can't override constructors. So if you're writing the API,
call overridable methods from your constructor. I don't understand what
you're doing discussing this on the Wicket user list - this is just
basic Java.
If you don't want to include a specialized method for initializing a
component (e.g. the way Servlet works) and expect the constructor to be the
primary means of building up the component, then the constructors should
follow good practice and all get called.
Errr, what? We don't get a choice here - this is all governed by the
language itself. I think you might be confused about how constructor
chaining works. Either that, or you're completely failing to make
yourself understood properly.
This is a common Java pattern. There should be only one place in the code
where properties are set from a constructor, all other constructors should
pass on their parameters, defaults if required, to the one constructor that
actually sets the properties.
This is nonsense. You write code to achieve what you want it to in the
most concise and simple way possible.
If that means a single constructor which actually does stuff with a
bunch of other constructors that delegate to it with default arguments,
then fine.
If it means you have a commonInit() method that all your constructors
call, then fine.
If that means you have a bunch of constructors that do different things,
then fine.
If you don't code well, you have three immediate problems which as an agile
fan, I would cringe at:
1) You have duplicate code, no way around it.
2) you can never be certain which constructor is called by the API and any
given point. You may be able to get it to work, but a future change to the
API could break your code, and you might well not catch it with your own
unit test (you have some right?).
Again; errr, what? No offense, but if you can't work out which
constructor is being called for a given bit of code, you probably
shouldn't be writing Java for a living.
Future API changes can always break your code. I don't see how that's
relevant specifically to constructors as opposed to anything else. If
someone changes the API and your unit test doesn't pick it up, your unit
tests are very obviously broken. Changing constructors is really no
different to changing other method signatures, with the possible
exception that you're slightly more likely to be doing reflection on
constructors than methods (although with the prevalence of Hibernate's
HQL and Wicket's PropertyModels even that is arguable).
3) in order to support having two overridden constructors, I now am *forced*
to duplicate my own code (granted it could be one line, but its still
duplication).
Errr, why?
Now... fixing the constructor calls is not impossible but may require a bit
of thought (I don't believe thinking is a problem for the developers of
Wicket as they have clearly done a lot of it already) however I personally
would prefer a specific method call for initializing the component... at the
very least so I don't have to do all that work in the constructor, but it
also has the benefit of being *very* easy to implement with the current
codebase.
Despite my preference for an init override, I think the correct thing to do
with or without it is to fix the constructor calls.
Fix them how? I still don't even remotely understand why you think
they're broken. I'm not being deliberately obtuse, defensive or
belligerent. I've read the original bug report. I just genuinely don't
understand where you're coming from.
What is to stop you going:
public BasePage() {
commonInit();
}
public BasePage(IModel model) {
super(model);
commonInit();
}
private void commonInit() {
add(new Label(myid1, foo));
}
?

It overrides #response(RuntimeException, RequestCycle) to check the

If it finds one, I send the user to a special error page.
The error will be vendor-specific, unfortunately.
I use something like this for MySQL:
