Re: How to protect against Session Fixation attacks?

[RUMikeP]

My appologies for the run-around.  I was not able to see the updates on the
Jira log yesterday from the office, so only managed to read the updates when
I got home.  

I have implemented the latest suggestion (included below for other
interested readers, although I suggest they read the Jira log as well),
which works perfectly:

/**
 * Replaces the underlying HTTP Session, invalidating the current one and
 * creating a new one.
 * 
 * Call upon login to protect against session fixation.
 *
 * @see http://www.owasp.org/index.php/Session_Fixation
 */
public void invalidateHttpSession() {
((WebRequest)RequestCycle.get().getRequest()).getHttpServletRequest().getSession().invalidate();
bind();
}

Many thanks once again for the great work!!

Re: 7th August London Wicket Event (6th August!)

[jWeekend]

Yiannis, Chris,

This is good to hear, thanks. We've been getting plenty of positive feedback
since we started this thing well over a year ago, albeit mostly verbally
until now. Perhaps your reviews here will make others aware of how much our
guests enjoy and look forward to these events.

The quality and variety of the presentations and the increasingly
interactive atmosphere we have been gently encouraging is definitely heading
in the direction I had envisaged from the start. There are a few more
improvements and unorthodox ideas that I want to gradually introduce in the
months to come which I think people would get into, especially now that we
seem to have established a healthy core group of regulars.

I'll talk to Al and we'll come back with some suggestions regarding the
frequency (if I get a chance I may set up a little Wicket component for our 
http://jweekend.com/dev/LWUGReg/ registration page  to gauge your feedback
so we don't swamp this mailing list). Several people have asked me about
this, so perhaps we could consider going back to "once a month", but I am
mindful that we do nothing to disturb the good balance and successful events
we are currently enjoying.

Regards - Cemal
http://www.jWeekend.co.uk http://jWeekend.co.uk  

PS To those who were present on August _6th_ (I don't know what event on the
7th you got us mixed up with Yiannis, but we'll accept the compliments ;-) ,
don't forget to send  http://jweekend.com/dev/ContactUsBody/ jWeekend a note 
if you'd like to be entered in the draw for the pre-paid 
http://manning.com/dashorst/ Wicket In Action MEAPS edition , let's say by
the end of next week.

You need to use something like Echo2 or Echo3 to write pure Java web
apps with no HTML whatsoever. All the HTML and all the AJAX is
completely transparent to the developer - it's more like writing a
desktop app than a web app which has benefits if you come from a
Java/C++ background and some disadvantages if you like having the power
to hack around with HTML and Javascript code.

With wicket you're still in control of the markup (HTML) which means you
have to write it but it's pretty straightforward. There is support for a
single section of markup to be overridden (inheritance) from a base page
markup to a derived page markup which means you can perform some level
of markup reusability at the page level. On some occasions I've found
the need to have multiple sections in a base markup to be 'overridable'
in a derived markup pages but this is not yet possible as far as I know.

I don't think that actually works in many (any?) browsers.

You probably need to put your  inside a  and style that instead.

Re: Help!! TextField in ListView = NULL

[Al Maw]

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  tag in a  and click a link?
What about if you put the  tag in a  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.

Alastair

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.

YUI DatePicker Changing default behavor

[nanotech]

Hi all,

I have multiple questions regarding YUI datepicker that I am using on my
project.

1. I have a from which has 6 DatePicker elements. Now it is possible that
user can open all of them opened which will make screen look bad. To prevent
that I would like to allow Only one calendar popup to remain open at a time.
So, as soon as user clicks on the other date picker icon (same form or same
Page)the first calendar popup disappears and re-appears at other place.

2. Also, The way YUI calendar works is that, when popup calendar comes up 
you have to either select a date or click on [x] icon to close. How can I
make calendar go away if user clicks anywhere on the form?



Thanks,
~R

This may be a client tag interpretation problem? Try using >>

Use firebug and/or the wicket ajax debug window (link bottom right on

Re: 7th August London Wicket Event

[Al Maw]

Thanks for the kind words. I really liked Carl's Terracotta stuff -
very cool. Wille's presentation on his WicketRAD framework was also
great. It's really cool to see people getting inspired by and building
on people's code from previous meet-ups! I can't begin to tell you how
rewarding that is. ;-)

Thanks very much to everyone who came along, asked such good questions
and gave the event such a nice feel. I'm definitely thinking about
increasing the frequency if people are keen (even if it's a less
formal gathering in a pub somewhere or something). It's somewhat
dependent on the number of people who'd like to give talks and things.
Who'd be up for a monthly event?

While we're on the subject, who might be up for doing a quick talk at
the next one? I was really impressed by the scope and preparation that
went into the talks this time around, but if you just want to do a
quick demo of your Wicket-based site, or give a five minute talk with
no slides and must arm-waving, that would be cool too.

Thanks again,

Alastair

P.S. Apologies for the slightly warm beer! It was cold at 6:15pm, but
the usual rooms next to a kitchen (with a fridge) weren't available
this time around. I promise we'll fix that for next time!

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?

yourself in ten minutes.

Re: Help!! TextField in ListView = NULL

I have add testsListView.setReuseItems(true), but still doesn't work.

  final Link editLink1;
  listItem.add(editLink1 = new Link("editLink") {

Browser Forward button issue

[Ritesh Trivedi]

Hi,

Here is the scenario 

1. User on page 1 - bookmarkable page which is https. lets say
https://localhost:8443/signIn
2. Submits the form on page 1 - gets validation error. The url now changes
to something like https://localhost:8443/?wicket:interface=:8:1:::
3. Hit the back button - user goes back to the sign in page - obviously no
validation errors displayed and the URL is https://localhost:8443/signIn
4. Hit forward button the URL in the browser now becomes the one with
validation errors https://localhost:8443/?wicket:interface=:8:1::: but the
server returns HTTP 500 with NoClassDefFountError

Help!! TextField in ListView = NULL

[Alvin_my]

Hi, 
I am very new with wicket and I have a problem with TextField within
ListView , I try to getModelObject from the Textfield but return NULL ?

I am trying my best to find the solution, unfortunately I am running out of
time with my final project. Already spent 2 days dealing with this small
problem :,( 

Hope you guys can help. Below is the some part of the codes:


textfieldModel = new Model("");
textField = new TextField("textfield",textfieldModel );
listItem.add(textField);

listItem.add(saveLink = new Link("saveLink") {
public void onClick() {
String myText = (String) textField.getModelObject();
info("###  myText  = "+myText );
}
});

Buy Wicket In Action from Manning Publishers -- it has a useful Wicket +

Re: modify an arbitrary dom element

[sander v F]

If you want to do in serverside (with wicked), you should add a wicket tag
to the 'li'.
 Home

the java/wicket code should look something like:

WebMarkupContainer listItem=new WebMarkupContainer("listItem");
listItem.add(new AttributeModifier("class",  new
Model("notSelectedItem")));
listItem.add(new PageLink("homePageLink", HomePage.class)));
add(listItem);

or as igor suggested, you could do it client side:
document.getElementById(link).parentNode.className="notSelectedItem";

Re: How to Embed PDF in a Web Page

[shetc]

Hi Igor,

Let me rephrase:

I am working with an Acrobat Form, which is a PDF with extensions to add
fields and buttons. These extensions include a button to submit an HTTP POST
to an URL. This all takes place within the Adobe Reader browser plug-in.

One of the features of an Acrobat Form is that a PDF can be built on the fly
to merge values with the form fields, and then streamed out from the server
to the client browser.

I would like to be able in a Wicket WebPage class to perform the merger and
then stream the PDF to the Adobe Reader browser plug-in. Ideally, I also
would like the plug-in to be embedded on the page in some fashion so that I
can put branding, navigation links, etc. around the PDF.

Thanks,
Steve

SecureMarkupContainer

[Ryan O'Hara]

I created a SecureMarkupContainer following Maurice's example (http:// 
www.nabble.com/Swarm%3A-Authorization--for-WebMarkupContainer- 
td17206272.html#a17219441), with the only difference being it's its  
own class (not subclass).  For some reason, the component doesn't  
seem to be added to the page after authenticating.  The correct  
values are returned by typeOfData.isAuthenticated().  However, it  
seems whatever hides/displays the component is not getting executed  
or executed correctly.  Below are some snippets of code:



Search:

SecureMarkupContainer typeOfData = new SecureMarkupContainer 
("typeOfData");

add(typeOfData);

Search.html:

security works!

cnv.hive:

	permission  
org.apache.wicket.security.hive.authorization.permissions.ComponentPermi 
ssion "${cnv}.Search:typeOfData", "inherit, render, enable";



Also, I have a few other secure components working fine (ie  
SecureLink).  Any ideas?

Re: modify an arbitrary dom element

[Igor Vaynberg]

you have to make it a component if you want to do it on serverside

if you want to do it on clientside you would do something like
document.getelementbyid(link).parentnode.style.foo=bar

modify an arbitrary dom element

[Brill Pappin]

I have a case where I want to modify the css class of the dom element  
that contains the component I'm working with.


I found the wiki page:
http://cwiki.apache.org/WICKET/how-to-modify-an-attribute-on-a-html-tag.html
but that will allow me to modify the component only.

Specifically what I'm doing is something like:


		Homea>



so I actually want to modify the css class of the containing li  
element (not the a element).
Is it possible to do it that way, and if not, does anyone have any  
suggestions on how this might be done better?

well, it is the way you setup the model by doing new model(value), so
the model acts as the container for the value rather then some glue
between value and some other container such as a class field. see the
models page on the wiki.

NPE

[Uwe Schäfer]

Hi

the current (1.4-m3) impl of

ComponentStringResourceLoader.loadStringResource(Class,String,Locale,String)

throws an NPE, that i am not sure of.

I´d suggest:

public String loadStringResource(Class clazz, final String key, final 
Locale locale,

final String style)
{
if (clazz == null)
{
return null;
}

// Load the properties associated with the path
		IPropertiesFactory propertiesFactory = 
Application.get().getResourceSettings()

.getPropertiesFactory();

while (true)
{

// new lines here:

if (clazz == null)
{
return null;
}

right ?

Re: Comparing JSF and Wicket

[Scott Swank]

If you can find JSF components that do exactly what you want then JSF
is more compact.  If, however, you find JSF components that do nearly
what you want, but you have to add a bit of functionality, well then
you're into the lovely world of phase listeners and the
request/response life cycle.  Dante located JSF phase listeners within
the 4th circle of hell if I remember correctly.

One of the first "ah ha" moments I had with Wicket was when I needed
to copy customer names from one field to another.  If a customer
purchases several items (tickets to shows, books a tour, reserves a
hotel room) then the guest name associated with one item is typically,
but not always, the guest name for all of the items.  With a nominal
amount of reasonably clear code I was able to create a behavior that I
simply attach to all of the first names and last names.  It copies the
value of one field to all of the matching fields that are empty and
updates all of these fields via ajax.  It's 22 lines if you don't
count whitespace & braces and it is completely reusable.  It can be
attached to any two or more form components and it just works.

public class ModelPropagationBehavior extends AjaxFormComponentUpdatingBehavior
{
private static final long serialVersionUID = -451063727688504933L;

public enum PREBUILT
{
FIRST_NAME, LAST_NAME;

public ModelPropagationBehavior getBehavior()
{
return new ModelPropagationBehavior(name());
}
}

private final String name;

public ModelPropagationBehavior(String n)
{
super("onblur");
this.name = n;
}

private String getName()
{
return name;
}

private boolean hasMatchingBehavior(Component component)
{
for (Object behavior : component.getBehaviors())
{
if (behavior instanceof ModelPropagationBehavior
&& ((ModelPropagationBehavior) 
behavior).getName().equals(this.name))
return true;
}

return false;
}

@Override
protected void onUpdate(final AjaxRequestTarget target)
{
final FormComponent thisComponent = getFormComponent();

thisComponent.getForm().visitChildren(new IVisitor()
{
public Object component(Component otherComponent)
{
if (otherComponent.equals(thisComponent))
return 
CONTINUE_TRAVERSAL_BUT_DONT_GO_DEEPER;

if (hasMatchingBehavior(otherComponent)
&& 
otherComponent.getModelObjectAsString().isEmpty())
{

otherComponent.setModelObject(thisComponent.getModelObject());
target.addComponent(otherComponent);
return 
CONTINUE_TRAVERSAL_BUT_DONT_GO_DEEPER;

}
return CONTINUE_TRAVERSAL;
}
});
}
}

Re: Comparing JSF and Wicket

I don't need nearly as much extensions for wicket because
it's such a no-brainer to write my own custom components...

I think JSF is a big joke with nobody laughing :)

How to include some parameters in template? Custom tag? Component?

[kan]

I have some page template which I want to include some blocks which
look same but some minor differences. Something like this
...

Please try our apple and play on our
cool apple computers.



So, after rendering my:productInfo could be replaced by some html
which may contain given product description, image, link to buy, etc.

I cannot to use  because it less obvious
and cannot give me structured parameters (like category, id) and I
have to add each wicket:id in .java-file, which could be annoying to
change two places.

I found wicket:component tag, but it's experimental and not recommended to use.

I think to implement own IComponentResolver to handle my:productInfo
tags. Is it the best way? Or is there other way to do it?

Re: MathML in wicket

After some reading i realised that wicket was overwriting my utf-8 header. I
managed to get it to work by changing
getResponse().setContentType("text/html"); to
getResponse().setContentType("utf-8"); There are now a number of display
errors, but certainly nothing unfixable.

Actually, I do not think that is completely far fetched. In my banking
applications I mostly follow the same path. In some applications there
may be a high change that the guessed path is correct.
Then again, it is easily fixed by starting at a random page version number.

In addition, many Wicket applications use bookmarkable pages. Easily
avoided if you're worried about CSRF of course.

Erik.

Martijn, this solution is correct but I tell that I said in post [1]...
Wicket is a framework where you can implement an easy solution but I prefer
that these types of solutions were distributed by default!

 Even encrypting the urls Wicket is vulnerable to CSRF because the key
 used
 to encrypt is shared by all users of application. Wicket is an
 extensible
 framework where you to add some new functionallity "easily" but it
 doesn't
 provide any secure solution by default to protect you against CSRF
 attacks!

Re: How to protect against Session Fixation attacks?

[RUMikeP]

Many thanks for the quick response. 

The pre-login session files in the temp filestore directory are not removed,
even after the session timeout.  All the new sessions are removed as they
expire, but the ones that are invalidated using the patch below remain
indefinitely.






no what you see is that by default the http session store has a new window
browser detection (new pagemap)
It needs that because of the way pages are stored and rollbacked.

The DiskPageStore doesnt need that it can get all the pages back that it
wants
so for that the new window detection is by default not enabled.

Old sessions are not cleand up with the diskpagestore?
What is not cleaned up?

Javascript in onBeforeRender

[Sarkast]

Hello everyone,

I have a small problem. I have a wicket component and the idea is that the
programmer can add numerous messages to it and whenever the component is
rendered some javascript is executed to iterate over the messages and
displays them.

I thought that I could simply override onBeforeRender(), or onAfterRender(),
but I simply can't figure out to append javascript. Basically I just want to
have a line of javascript executed, like
"messagebox.displayMessage('asdasdasd')". 

Before someone asks why I just don't add a label with the message, the
messagebox is dragable, fades after a while and should display messages for
a set amount of time (before the next message is displayed) and should also
be used on client side without requests.

Any thoughts? Help would be appreciated.

Tom

Re: How to protect against Session Fixation attacks?

[RUMikeP]

Hi 

Still busy looking into it, but using the suggested fix posted by Enes Fazli
I notice two strange behaviours:

If I use the default FileSessionStore, the URLs are as per normal, e.g.
wicket:2 but if I change to HttpSessionStore then I get an additional "-0"
appended, e.g. wicket-0:2

In addition, it appears that the old sessions get invalidated at login time
are not cleaned up.

Any suggestions/starting points would be most welcome

Many thanks 
Mike

Re: Questions about wicket features

[Johan Compagner]

CSRF uses urls to do something on another side right?
for example

http://bank.example/withdraw?account=bob&amount=100&for=mallory";>

How would that work in a default wicket application?
Is it really so stupid developed that these kind of things uses client side
state?

So this cant be done with just an url. So you have to have real scripting..
So for this to work in wicket you have to know upfront so many things..
First the page id of the bank transfer page.. Which is pretty random. Only
if all users would go over the same path always to the same page
then the id could be guessed.
Then it has to get the right form, fill in the right values and do the
submit

And do modern browsers allow js script like that?

I'd also like to pass on my thanks, I enjoyed meeting and chatting to you all

If anyone reading this happens to be in/near London when one of these events

of experience with Wicket.

PageParameters

[Uwe Schäfer]

hi

coming from 1.3.x i stumbled upon

public PageParameters(final Map parameterMap).

shouldn´t this be:

public PageParameters(final Map parameterMap)
or
public PageParameters(final Map parameterMap)

sorry, if this was discussed alreadys, but i did not follow the generics 
discussions so far.


my usecase is something like:

new PageParameters(Maps.create(someString, someInt))
where
Maps.create is defined like:

public static  Map create(final 
KS k, final VS v)

Re: Questions about wicket features

[Martijn Dashorst]

This assumes that the hacker correctly guesses the application key
(which you of course changed from the default setting), or has access
to your application to harvest URLs.

Making the SunJceCrypt user specific is as simple as:

new SunJceCrypt() {
@Override public String getKey() {
   return MySession.get().getUserKey();
}
}

And all you have to do is implement your own user key generation that
generates a key based on some random information and is constant
throughout the session (e.g. md5 sum of a salt + Random.nextInt).

Re: Questions about wicket features

[Arthur Ahiceh]

ok! you have not used the word "easily" but only saying "There are more
hardening options such as encrypting urls" it only seems that encrypting
urls  the problem is solved and it is not the case! The user has to
implement a custom security factory, one different than provided by Wicket
(SunJceCrypt), to resolve CSRF.

7th August London Wicket Event

[Yiannis Mavroukakis]

Hi everyone,

Just wanted to say a quick thank you to Cemal, Al et al for organizing 
this event, last night was very informative,

especially the Terracotta presentation.
The only gripe I've got (besides warm beer :-P ) is the frequency of the 
event..I think bi-monthly is far too far apart for
such a fast paced framework as Wicket..Any chance this can be done on a 
monthly basis?


Thanks!

Ioannis

Even encrypting the urls Wicket is vulnerable to CSRF because the key used
to encrypt is shared by all users of application. Wicket is an extensible
framework where you to add some new functionallity "easily" but it doesn't
provide any secure solution by default to protect you against CSRF attacks!

Re: Turn off SWARM

[Johan Compagner]

then you should really look around so that you can use the hotcode/swap of
the jvm
Tomcat shouldnt rebuild/redeploy constantly on every change in development
thats quite annoying if you ask me

If you use eclipse and you want to use tomcat use the sysdeo plugin
else just use jetty (see our quickstart)

Re: ListView in Forms

[Markus Haspl]

no, there aren't any errors.

but i don't understand why i have to use propertiesName.getModelObject(); in
the onSubmit() method. Because there may be hundrets of propertiesName in
the ListView/Form.

Would it be better to make a Forms in a ListView? But then i need for every
Form a submit-button. that wouldn't be so nice...

thanks

well, if we are talking in purely managerial/economical terms then i
would definately go with jsf.
a) it is always easy to find very high-paid consultants to rescue a
project that is running late or is totally broken, lots of companies
out there offer jsf consulting services
b) it is much easier to find someone to replace you when you screw up,
there are many more job postings for jsf then for wicket
c) it is much easier to find someone to replace you when you ask for a
raise, see above

if you cannot find this on your own then i dont think you will enjoy
wicket at all. wicket is not about serving up everything on a silver
platter. the answers to these questions are only a short trip away
from looking at wicket-examples.

Always look at the facts, never just go on a hunch. What may sound
like common sense, especially from a managerial point of view, not
always is that sensible. In this case, while having a whole bunch of
standard components might sound good and sell well, you have to wonder
how much time it actually saves you. Very often you'll have to
customize components to exactly fit your needs. How hard is that, and
is it possible at all is something you need to look at. The fact that
component lib X has a datagrid component doesn't mean it fits your
needs. It might be inflexible or - when it is flexible - hard to use
because the API is big and clumsy.

The great thing about custom components is that extending a base
component often is just as easy or even easier than having to figure
out an of the shelf component that does it all but needs to be
configured for a specific use case. Also, because you'll make it fit
to your needs without having to do lots of configuration, you'll
likely avoid a lot of code duplication, and it might be easier to
optimize for specific cases because you can access internals more
easily.

> This is a classic advantage a standard solution usually offers - a thriving

And again, look at the facts. If you look past the marketing slogans
en count the available high quality components for the two frameworks,
I honestly don't think the difference is that huge. I actually expect
Wicket's community to do a bit better. And we don't need as many
components because extending a baseclass is very often a more
efficient way of customizing than designing complex components upfront
and guiding them through configuration.

You'll have to do your homework here. It's simple, just check out the
Wicket core projects, and a bunch of wicket-stuff projects in your IDE
of choice, and look for an inheritance view (F4 in Eclipse) of the
Component class and see what components there are. We can't really
give meaningful numbers imho, because many components gradually go
from covering just base functionality to supporting very specific
functions (like TreeTable or tables with sorters and filter fields).
You should also consider doing the same thing for the IBehavior
interface, because often you can add behavior to a component through
behaviors.

Final remark... it seems that many people are always looking for
'winners' and 'losers'. Why don't you just take the projects you're
thinking off, see what you really need and match that with the
frameworks you're evaluating, and try to get a hunch of what it would
be like to actually do these projects with the frameworks so that you
can decide whether it would fit your needs?

So see the markup of DataTable -- you are gonna see those spans there :-) As
Igor said, the easiest way is to use a Fragment (or Panel, as you wish).

If you really want to find out, nothing beats looking at it yourself.
Those articles could provide you with a framework, and you just have
to check whether the arguments hold today and whether you agree in the
first place. Or take a few evenings/ weekend and set up a little hobby
project yourself to see how the two frameworks 'feel' when you work
with them.

Re: Comparing JSF and Wicket

[nlif]

Thanks Igor,

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.

This is a classic advantage a standard solution usually offers - a thriving
ecosystem. (than again, I've got to admit, I don't really know that much
about JSF's ecosystem...).

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)?

Thanks again,
Naaman

Re: Facebook Wicket Integration

[Benny Weingarten]

Thanks Cao, but I don't see how this helps me.

Let me further explain my situation. 
1) I need to display links to the users of my facebook application. These
links are DYNAMIC, so I can't put them in the markup. I have to use some
sort of wicket Link component.

2) In your example, the URLs are relative URLs, as opposed to the absolute
URLs that I want to display to the user.

In my application, all the links (currently) are relative links, i.e. when I
hover over the link when the application is running in facebook, the URL
displayed at the bottom left corner of the screen is:
http:///
But I would want them to be:
http://apps.facebook.com//

My trouble with achieving this is described at my previous post on this
thread. Any further assistance on this matter would be appreciated.

thanks,
Benny.
