take maurice's post and substitute word permission for word principal,
define user/principal as an object that has a set of permissions, and it
makes perfect sense.

I've had a pretty good look at wicket security but the conclusion that
I've
come to with that is it only supports the fact that you have pre
defined
roles within your application.

I'm currently working on a multi tenant web application where the
application provided a set of permission, such and read / write access
to
an
object and each tenant in the application defines their own role
heirachy
based on those permissions.

Correct me if i am wrong but this seems to be what you want too.

We are currently using acegi and I'm trying to figure out the best way
to
bake acl into wicket's components. Example, a link is set to invisible
if
the authenticated use doesn't contain a role with the given permission
of
that link. So lets say the link is to delete an object, the user must
have
a role with the permission to delete that object or the link will not
show
on the page.

If you mean java Jaas like acl than swarm is what you are looking

Optionally if you really want to use jaas and not some look alike i
made up you could practically copy swarm and replace most objects
with
there jaas counterparts.
However i chose not to use jaas because we are using that in one of
our projects right now and although it works it is less than optimal
:) As soon as we make the switch to wicket 1.3.0 jaas will be
replaced
by swarm.

2007-06-29 Thread Flemming Boller


I would at least try two thing.

System.out the classloaders of the getSession() class and the Typecasted
class. That way you know for sure.  If the two classloaders is

sun.misc.AppClassLoaderand the other is
ContextClassloader (or something like that)  then you know that one class is
loaded by
jvm classloader, and the other is by jetty.

What that mean is that you either have some jar files in you classpath or in
WEB-INF/lib or you have some classes in WEB-INF/classes that uses jar files
in you classpath.

 Reading at some Jetty forums about other similar problems I found out

 BUT Intellij did not do that. It just referenced the jar files in my

 So, after setting Intellij to compile to project-root/classes it worx

 I hope somebody can use this, because...dammit this has taken time...

 Well thanks for you quick responses!

 /Flemming

Flemming,

I wonder if you might explain what caused your problem in a little more
detail as my rather simple mind didn't quite comprehend. ;)

I am receiving the exact same error as you and I suspect that the cause
lies
in something like the same area, however our situations do appear to be at
least slightly different.

I am using the ReloadingWicketFilter. One of the dangers one must watch
out
for when using it is loading the same class in two different classloaders
exactly as you described. I am using Maven 2 and mvn jetty:run to deploy
my application for local testing. Everything seems to work fine until I
use
my browser back button and click on a link from the page I went back to;
any
link. At that point I receive the exact same exception you described
earlier
in this thread. If I disable the ReloadingWicketFilter, then the
application
behaves normally and I do not receive an error.

I compile my classes to the default location (i.e.
module_home/target/classes) and I see that when maven starts, this
location
is added to the classpath. For additional information, one could look at
the
thread where I've been hashing through this:

http://www.nabble.com/http://www.nabble.com/Re%3A-Using-hot-reloading-of-classes-with-Spring-%28Was%3A-Has-something-changed-in-markup-inheritance-%29-p11335416.html

Clearly, I'm loading my custom WebSession class into two different
classloaders, but for the life me I can't figure out where or how. Given
your experience, do you have any suggestions?

Matt

Re: [Wicket-user] wicket security and acl files

2007-06-29 Thread Maurice Marrink

Actually that is already how they work. Even though the Principal
class does not have methods for getting and setting the Permissions.
The mapping is done in the policy file like this.

grant principal ${RechtenSet} PageA.read
{
//read permission for all of page A
permission ${ComponentPermission}
nl.topicus.krypton.web.pages.PageA, inherit, render;
};
grant principal ${RechtenSet} PageA.write
{
//write permission for all form components on page A
permission ${ComponentPermission}
nl.topicus.krypton.web.pages.PageA:form, inherit, enable;
};
grant principal ${RechtenSet} PageA.delete
{
//allow separate delete links to be clicked
permission ${ComponentPermission}
nl.topicus.krypton.web.pages.PageA:deleteLink1, enable;
permission ${ComponentPermission}
nl.topicus.krypton.web.pages.PageA:deleteLink2, enable;
};

I know the api doc for principal states which can be used to
represent any entity, such as an individual, a corporation, or a login
id. I admit it is shamelessly copied from java.security.Principal :)
And now that i think about i can see the way we use principals like
permissions now actually comes from our dealings with jaas. But i
still feel it is not a big issue. I'll just rewrite the api doc ;)

   Well i am not saying it is impossible to declare and add new
   permissions / principals at runtime but i think it is generally
   undesirable to do so. Instead you should make your principals fine
   grained enough to be used as building blocks for  roles.

   application provided a set of permission, such and read / write access
 to
   an
   object and each tenant in the application defines their own role
 heirachy
   based on those permissions.
  
   This is exactly what we are doing in our application. We have
   literally +- 1000 principals defined in our system. By allowing the
   users to group principals together they can build there own roles. We
   have multiple organizations in our application and each of them can
   completely redesign there user roles in the system (well only up to a
   point because we could not allow that, but that aside they could). We
   provide each organization with a set of default roles as we think will
   suit most of them but they are completely free to alter/ rename/
   delete/ whatever do with those roles because we do not depend on the
   roles but on the underlying principals, which are controlled by us. A
   big help is the fact that we made our principals imply each other
   (write implies read, etc)  So when a user designs there roles they
   don't have to check read access to page A and write access to page A
   but can suffice with write access to page A. Although most of our
   principals handle a couple of related pages we also have principals
   going as deep as individual components. For instance we have a large
   data grid, the principals are fine grained enough to give you read or
   write access up to the individual cell.
  
   Correct me if i am wrong but this seems to be what you want too.

 set a breakpoint and make sure your if clause is getting hit. the

 might get wrapped in another, so you might have to search for root cause
 and
 do instanceof on that.

yu can use String.length to do dat. but be aware it might jumble your table

I had to make that trade off as well

Re: [Wicket-user] AjaxTabbedPanel and back button (Wicket 1.2.x)

2007-06-29 Thread Paolo Di Tommaso

Eelco .. I understand, and moreover in general versioning on ajax operation
is meaning less.

But in some cases like tab operation would be nice, because from the user
point of view changing tab switch is like changing the page content. So
would be useful to let interact with browser back and fwd navigation.

Looking on the Internet I found some interesting tricks [1] and [2].
Basically that make use of a hidden iframe to store the history.

Perhaps a solution to handle versioning for a generic ajax action could be
very complex.

But a specific behaviour just to handle AjaxTabbedPanel versioning I think
it would not so difficult.

I will make some experiment and let you know.

FYI Paolo, we've been chatting about this before and had some ideas,
but it's a hard problem to solve. Unlike GWT (who does a good job
supporting the back button with Ajax), Wicket doesn't 'own' the
browser, so we'd have to use complicated workarounds, especially since
it has to be aligned with our normal page versioning. But biggest
problem right now that keeps us working on this is lack of time.

Re: [Wicket-user] replaceWith() not working


it is not by accident an ajax request right?

 Code looks fine to me. And I'm using replaceWith quite a bit and it
 works fine. Can you try to set a break point in onClick, see if it
 arrives there and step into the replace code?


The onClick() is definitely getting called (I set breakpoints this
morning...) but the panel just isn't getting replaced.  Now, is there any
problem with replacing a link (in this case) with a panel?  There's no
impedence mismatch between the a and the span that would normally get
used?

Re: [Wicket-user] Session.dirty()


i guess it could be public, it isnt public because most of the time
you alter a variable inside session and then call dirty on the session
itself
But if you know your object is hold on to by the session and you are in that
object
itself, changing it then yes you also have to call dirty so i guess for this
kind
we just make it public.

Hi,
I am in the process of making wasp and swarm play nicer within a
clustered environment.
Johan suggested calling dirty() whenever i make a change in the
session (which is where i store everything indirectly). But because i
have login method on my authorization strategy (which should call
dirty after a login) and Session.dirty() is protected i can not call
dirty unless i expose it in my WaspSession. Before i do that however i
thought i check here if there was a special reason not to make dirty()
public. I could not come up with one especially since bind is also
public which kind of has the same (side)effect.

So my question, what is the reason dirty() is not public and if there
is no reason could you make it public.

Thanks,

Maurice

that should be simple, although my wicket is bit rusty at the moment, I
think

final TextField tx = new TextField(cell, new
PropertyModel(values[row][col],data));
 tx.add(new IValidator(){
 public void validate(FormComponent fc){

 if(fc.getValue() is greater than 20){
   fc.add(new AttributeModifier(style,true, new
Model(background-color: #FF;)));
   fc.error(error.toolongvalue,null);
 }else{
 fc.add(new AttributeModifier(style,true, new
Model(background-color: normal-color;)));
}

   }
 });
item.add(tx);


something like dat...just buzz around

[Wicket-user] Paging data without using DataProvider.size() ?

Hi,

  Anyone got any suggestions as to the best way to provide a paging
data view without requiring using size() to actually count the records
in DB?

I've got a site that has a production DB such that
select COUNT(*) from mytable
takes a non-trivial amount of time/cpu to return, whereas to get
the actual data for the page is effectively immediate!

I'm curently using a DefaultDataTable and the quick hack is to just
hard-code DataProvider.size() to just return a fixed number, but while
that's probably OK, it's sub-optimal (it is just a util for my own
use though, really).  Having said that, I'd be interested in
alternative suggestions.

It's the Production DB only that shows this behaviour (which is
probably related to them not purging the the old data for 4 years or
so, so I'm limited as to what might be possible with the DB itself).

Re: [Wicket-user] Paging data without using DataProvider.size() ?

The most interesting questions is of course: what database? Perhaps
someone here knows how to get the count(*) faster? you might want to
do a select count(primary_key) instead of *.

As an answer to your question: you could use Integer.MAX_VALUE.

[Wicket-user] RefreshingView and Link.setAutoEnable

2007-06-29 Thread Vadim Tesis


all,

i'm trying to create a list of links using Refreshing view in wicket 1.3.  
for some reason if i call Link.setAutoEnable(true) it doesn't really work, 
the link is enabled all the time.  however if i override Link.isEnabled() 
method it works, the link becomes disabled on the page it points to.   
there're 3 classes: BasePage, and HomePage, SignInPage which extend 
BasePage.  i'm creating RefreshingView in the BasePage.

the code is below.  am i doing something wrong?

Thanks,
Vadim

HTML:
ul 
   li wicket:id=refreshingView
 a href=# wicket:id=item[Item Here]/a
   /li
/ul

Java:
public class BasePage
{
Form form = new ...;
final ListIModel items = new ArrayListIModel();
items.add(new AbstractReadOnlyModel()
  {
 private static final long serialVersionUID = 1L;
@Override
 public Object getObject()
{
return (new Link(item)
{
//@Override
//		  public boolean isEnabled() { return (getPage().getClass() != 
HomePage.class); }

  @Override
  public void onClick() { setResponsePage(HomePage.class); }
// });
}.setAutoEnable(true));
}
 });
items.add(new AbstractReadOnlyModel()
{
private static final long serialVersionUID = 1L;
@Override
public Object getObject()
{
  return (new Link(item)
{
//  @Override
//		public boolean isEnabled() { return (getPage().getClass() != 
SignInPage.class); }

@Override
public void onClick()
{ setResponsePage(SignInPage.class); }
//  });
}.setAutoEnable(true));
}
   });

form.add(new RefreshingView(refreshingView)
{
@Override
protected Iterator getItemModels() { return items.iterator(); }
@Override
protected void populateItem(Item item_)
{
   AbstractLink al = (AbstractLink) item_.getModelObject();
   if (item_.getIndex() == 0)
	 item_.add(new AttributeAppender(class, true, new 
Model(firstelement), ));

   item_.add(al);
}
   });

add(form);

How would the Link know to which page it is linking? You need to provide

protected boolean linksTo(final Page page)

See the code for Link#isEnabled():

/**

public boolean isEnabled()

// If we're auto-enabling
if (getAutoEnable())

// the link is enabled if this link doesn't link to the

Heh, you have too much awe for Wicket: that would require either
running the onClick upfront (the isenabled check also determines how
the link is rendered!), which can have a lot of consequences, or
analyzing the bytecode (which may have some security issues), and try
to come up with something magical.

 so, in this use case is there any difference whether to override linksTo()
 or isEnabled()?  i think overriding isEnabled() is more generic, if latter
 i'll need to add more logic to disable the link this will be the place to do

This is a correct analysis of the situation.

2007-06-29 Thread Matej Knopp

What we should have is some kind of listener. Which you could use to
easily plugin your own behavior (even dumpThreads if you want). I
wated to do this some time ago, but then we stopped getting those
exception so i let it be.

 this would be extremely useful when this exception is thrown!

 We've had a thread about that, and the conclusion was that this is

  Code looks fine to me. And I'm using replaceWith quite a bit and it

 The onClick() is definitely getting called (I set breakpoints this

 problem with replacing a link (in this case) with a panel?  There's no
 impedence mismatch between the a and the span that would normally get

Re: [Wicket-user] wicket security and acl files

2007-06-29 Thread craigdd


Just my two cents but I think the API should change, or I guess not really
the API but the implementation(swarm) to better reflect industry naming
standards which will hopefully cut down on the confusion and hopefully make
it a little easier to integrate other security frameworks.

I use acegi as an example, they have an Authentication object that has a
method getPrincipal which if you read their javadoc makes it pretty clear
that an authenticated entity has one principal, which also seems to fit with
JAAS.

 to
  an
  object and each tenant in the application defines their own role

  This is exactly what we are doing in our application. We have
  literally +- 1000 principals defined in our system. By allowing the
  users to group principals together they can build there own roles. We
  have multiple organizations in our application and each of them can
  completely redesign there user roles in the system (well only up to a
  point because we could not allow that, but that aside they could). We
  provide each organization with a set of default roles as we think will
  suit most of them but they are completely free to alter/ rename/

  roles but on the underlying principals, which are controlled by us. A
  big help is the fact that we made our principals imply each other
  (write implies read, etc)  So when a user designs there roles they
  don't have to check read access to page A and write access to page A
  but can suffice with write access to page A. Although most of our
  principals handle a couple of related pages we also have principals
  going as deep as individual components. For instance we have a large
  data grid, the principals are fine grained enough to give you read or
  write access up to the individual cell.
 
  Correct me if i am wrong but this seems to be what you want too.

Re: [Wicket-user] wicket security and acl files

2007-06-29 Thread Maurice Marrink

I am open to suggestions for alternate names, or if someone could
point me to the naming standards :)

Right now swarm operates the following way: A user is associated with
1 or more Subjects, each Subject has 0 or more Principals. Each
Principal is mapped to 1 or more Permissions.
Each Permission has 0 or more Actions.

Permissions and actions are named pretty straight forward i think.

Re: [Wicket-user] wicket security and acl files

2007-06-29 Thread craigdd


The way it sounds is that principal should really be renamed to role.  Roles
typically have 0 or more permissions.

Although if you consider the hive as a mapping of roles to permissions then
you are really back to what I said earlier where swarm is handy if your
application pre-defines the roles that are available.

 We
   have multiple organizations in our application and each of them can
   completely redesign there user roles in the system (well only up to
 a
   point because we could not allow that, but that aside they could).
 We
   provide each organization with a set of default roles as we think
 will
   suit most of them but they are completely free to alter/ rename/
   delete/ whatever do with those roles because we do not depend on the
   roles but on the underlying principals, which are controlled by us.
 A
   big help is the fact that we made our principals imply each other
   (write implies read, etc)  So when a user designs there roles they
   don't have to check read access to page A and write access to page A
   but can suffice with write access to page A. Although most of our
   principals handle a couple of related pages we also have principals
   going as deep as individual components. For instance we have a large
   data grid, the principals are fine grained enough to give you read
 or
   write access up to the individual cell.
  
   Correct me if i am wrong but this seems to be what you want too.

[Wicket-user] RestartResponseAtInterceptPageException / continueToOriginalDestination

2007-06-29 Thread Mark Southern

I have an authorization scheme where by the user is presented with a
sign in page. After signing in, a check is made to see if they need to
change their password. If so, they are redirected to a change password
page. After that they should be redirected back to their intended page. 

 

However, if I use a RestartResponseAtInterceptPageException(); to go to
the password change page from the sign in page, after submission I get
directed back to the sign in page. Can I specify the intended original
destination without setting a response page and passing it as a page
parameter?

 

Thank you,

 

~Mark

Re: [Wicket-user] Paging data without using DataProvider.size() ?

2007-06-29 Thread Scott Swank

Any modern database uses a cost-based optimizer to determine its
query execution plans.  This means that at a minimum the database
knows how many rows each table contains.  This means that you just
have to find this metadata -- then you can use that in lieu an actual
count(*).

On oracle you would:

select num_rows
from all_tables
where owner = 'FOO'
and table_name = 'BAR';

instead of

select count(*)
from foo.bar

Re: [Wicket-user] Paging data without using DataProvider.size() ?

2007-06-29 Thread Scott Swank

Of course this metadata-level cardinality may be generated daily and
hence may not be current, but for the purposes of paging it's probably
entirely sufficient unless you expect a user to walk through many,
many pages of data.

 The most interesting questions is of course: what database? Perhaps

 As an answer to your question: you could use Integer.MAX_VALUE.

The DB's Oracle (8i, I think), but the metadata approach doesn't help,
as if I'm using size, it should be the size for the filtered results,
which may be in effect, otherwise I might as well use a fixed result.

What I was wondering was if anyone had any suggestions about a table
object that just did 'next'/'prev' paging, rather than working out
Page N of M, although I'll try  work out if select count(id) is
faster/less cost than select count(*)

NavigationHeader, but would be dynamic (when the table is filtered),
so a counts table wouldn't work.

I think the key this time is just to accept some loss of functionality
(jumping direct to a page) is that allows me to do away with the call
to size(), but I just wanted to check I wasn't missing a better way
than drilling my way down into DefaultDataTable.

Re: [Wicket-user] wicket security and acl files

2007-06-29 Thread Eelco Hillenius

 Right now swarm operates the following way: A user is associated with
 1 or more Subjects, each Subject has 0 or more Principals.

This sounds right to me, and is like how JAAS works.

A subject is the root/ abstract entity for a user, principals are
views or identities of a subject and in JAAS you would represent a
role as a principal.

As JAAS is the default authorization mechnism in Java, it is arguably
the 'industry standard' (for Java). Whether it is what you prefer is
another question. I think people find users/ roles easier to
understand, but personally I like the more abstracted model of JAAS;
whether you want to model groups, roles a combination of the two or
even something different, it fits seamlessly.

Re: [Wicket-user] AjaxTabbedPanel and back button (Wicket 1.2.x)

2007-06-29 Thread Eelco Hillenius

 Eelco .. I understand, and moreover in general versioning on ajax operation
 is meaning less.

 But in some cases like tab operation would be nice, because from the user
 point of view changing tab switch is like changing the page content. So
 would be useful to let interact with browser back and fwd navigation.

We don't actually think it is meaningless. Just very hard for us to
implement. We (or rather, Johan) did some work preparing the server
side for this, and we have been talking about it a lot behind the
scenes (yesterday even), but we probably will need a couple of weeks
of intens work to really get this working. If we would be able to pull
this off at all, which tbh isn't a certainty right now.

 Looking on the Internet I found some interesting tricks [1] and [2].
 Basically that make use of a hidden  iframe to store the history.

Thanks. We were already aware of those techniques though. The main
problems we are facing are:
* Currently we don't assume pages are using ajax per se. We don't
'own' the browser, an we don't have a unified model of how ajax has to
work.
* We have to align the ajax versioning with our normal versioning,
which is not easy.

 Perhaps a solution to handle versioning for a generic ajax action could be
 very complex.

 But a specific behaviour just to handle AjaxTabbedPanel versioning I think
 it would not so difficult.

 I will make some experiment and let you know.

If you up with something smart, please share! :)

Cheers,

Eelco

 A subject is the root/ abstract entity for a user, principals are
 views or identities of a subject and in JAAS you would represent a
 role as a principal.

I agree with your statement which leads me to the fact that the principal
should really be a role in swarm and the hive file is a mapping of a role to
given permissions and actions.  So back to what I said before, swarm is
really nice when you have an application with pre-defined roles instead of
an application that is more fluid and tenants can create their own structure
of roles.

[Wicket-user] How to manage state / session for different windows/tabs


Hi guys, I have the following task. I'm building a simple calculation page,
but for sake of simplicity lets say I'm doing the adding link sample we all
know.

I might need to be able to open two browsers or tabs to be able to do
parallel calculations and compare both results. Lets say click 3 times on
the link and have *3* on one window/tab and click 4 times in the other one
and have *4*, instead of 7 which is the default behavior.


Know this point its kind of arguable, so I need to find ways to both doit
and may be recommend against it as it may not be a good practice.

To put this in a concrete question:

Is it possible to handle each instance of a browser (Being this a window,
either a new tab or new window, or even a new process)  like a new session
instance?

To do a little test I built a small application with only a home page that
prints out a UUID randomly generated in my MyWicketSession. Very simple
code, in the session constructor:

this.UUID=uuid = UUID.randomUUID().toString();

and in the Home page

*info*(getMyWicketSession().getUUID());

This generates the same value when I hit a new tab and enter the URL or when
I ask the browser for a new Window.

This must be the correct behavior and I have nothing against it, but can I
have independent state management. I don't want to go sessionless.


Best regards,
f(t)

ayyayay, i guess no matter how you try to engineer the api people always
find ways to abuse it :)

TextField tf=new TextField() { oncomponenttag(tag) { if (!isvalid()) {
tag.put(class,error); } }};

  I had to make that trade off as well
 
  i am looking for some javascript technique maybe yu can show me if yu

  Look for a javascript library that can allow a user to dynamically

  each Textfield

   The Cell object is from JExcel and its where Datatype should be

   2. To validate,
  
   You can write a default wicket validator (See Validator examples),
   The validator can access the Textfield arrays and then check for

   its shouldn't be too difficult anyway

To put this in a concrete question:

Is it possible to handle each instance of a browser (Being this a window,
either a new tab or new window, or even a new process)  like a new session
instance?

To do a little test I built a small application with only a home page that
prints out a UUID randomly generated in my MyWicketSession. Very simple
code, in the session constructor:

this.UUID=uuid = UUID.randomUUID().toString();

and in the Home page

*info*(getMyWicketSession().getUUID());

This generates the same value when I hit a new tab and enter the URL or
when I ask the browser for a new Window.

This must be the correct behavior and I have nothing against it, but can I
have independent state management. I don't want to go sessionless.

It is possible what you have one page instance/version opened in three
tabs. How does the link you are clicking on when creating new tabs
look like?

Re: [Wicket-user] How to manage state / session for different windows/tabs


I think you misunderstood. First of all, I don't have any problems.

Is just a question, that is intended to get insight in this matter.

If you have an adding link like the one in the samples. And click it any
number of times, it adds +1, the number of times you click on it.

If you click 3 times, you get a 3. Then if you open a new tab, and click on
the link on the new tab, you get 4. not 3. Again, to dissipate confusions, I
don't think that is wrong at all. But I was just asking if it is possible to
have multiple states in multiple tabs.

thanks,

f(t)

Re: [Wicket-user] How to display a BufferedImage on Wicket Component

2007-06-29 Thread Philip A. Chapman

Take a look at WebResource or DynamicWebResource for serving up your
BufferedImage.  You'll just need to put an img src=# wicket:id=foo
tag in your html, then in your java, provide the correct url to the
WebResource for src.

the answer is yes, and it is also transparent - eg you dont have to do
anything as long as you use default page store

if you use sessionstore then you need to turn on that setting i told you

count(not_nullable_column).  Stick with count(*), since it's clearer
what you really want.

  As an answer to your question: you could use Integer.MAX_VALUE.

 The DB's Oracle (8i, I think), but the metadata approach doesn't help,
 as if I'm using size, it should be the size for the filtered results,
 which may be in effect, otherwise I might as well use a fixed result.

 What I was wondering was if anyone had any suggestions about a table
 object that just did 'next'/'prev' paging, rather than working out
 Page N of M, although I'll try  work out if select count(id) is
 faster/less cost than select count(*)

I think you misunderstood. First of all, I don't have any problems.

Is just a question, that is intended to get insight in this matter.

If you have an adding link like the one in the samples. And click it any
number of times, it adds +1, the number of times you click on it.

If you click 3 times, you get a 3. Then if you open a new tab, and click
on the link on the new tab, you get 4. not 3. Again, to dissipate
confusions, I don't think that is wrong at all. But I was just asking if it
is possible to have multiple states in multiple tabs.



the answer is yes, and it is also transparent - eg you dont have to do
anything as long as you use default page store

if you use sessionstore then you need to turn on that setting i told you
about.

Hi guys, I have the following task. I'm building a simple

 sample
  we all know.
   
I might need to be able to open two browsers or tabs to be able to
 do
  parallel calculations and compare both results. Lets say click 3 times
 on
  the link and have 3 on one window/tab and click 4 times in the other
 one and
  have 4, instead of 7 which is the default behavior.
   
   
Know this point its kind of arguable, so I need to find ways to
 both

To put this in a concrete question:
   
Is it possible to handle each instance of a browser (Being this a
  window, either a new tab or new window, or even a new process)  like a
 new
  session instance?
   
To do a little test I built a small application with only a home
 page
  that prints out a UUID randomly generated in my MyWicketSession. Very
 simple
  code, in the session constructor:
   
this.UUID=uuid = UUID.randomUUID().toString();
   
and in the Home page
   
info(getMyWicketSession().getUUID());
   
This generates the same value when I hit a new tab and enter the
 URL or
  when I ask the browser for a new Window.
   
This must be the correct behavior and I have nothing against it,
 but can
  I have independent state management. I don't want to go sessionless.

Re: [Wicket-user] How to manage state / session for different windows/tabs

2007-06-29 Thread Matej Knopp

Err, the fact is, it turned out that there are some flaws considering
multi window support and secondlevelcachesessionstore (default). So in
case you are experiencing any problems, you should turn on multiwindow
support (manually) even for SecondLevelCacheSessionStore.

Re: [Wicket-user] Trying to retrieve the absolute URL

2007-06-29 Thread ZedroS Schwart

Hi

I had already asked a similar question months ago. As I remember it,
the possibility to get the absolute URL had been left over since it
could be misleading depending of the actual deployement.

As such, you have to save it somewhere in your app and call it when needed.

But it's just some memories...

Cheers

 This is how:

 WebRequest request = getWebRequestCycle().getWebRequest();
 String baseUrl = request.getURL();


 The API docs say:

 getURL

 Retrieves the absolute URL of this request for local use.

 Returns:

 However, I am getting something that looks like

 /hello///?wicket:interface=2:form.requestPassword::IFormSubmitListener

 I don't mind anything after the ?, but I do need the _absolute_ URL,
 meaning everything in the form I wrote above.

 Did I misunderstand the API docs?

you have access to httpservletrequest from which you can reconstruct the

((webrequest)getrequest()).gethttpservletrequest()

The O'Reilly open source convention is happening July 23-27 in Portland
Oregon (USA):

  http://conferences.oreillynet.com/os2007/

Are there any Wicket people coming to Portland for OSCON?

I could organize an informal gathering or (perhaps) an official
