Re: [DISCUSS] Security Frameworks

2012-10-22 Thread Erik van Oosten


[ X ] I use my own custom framework
[ X ] I use Shiro
 

For my current Wicket project we started out with Shiro as it promised 
to be easy to use. However, even though Shiro is feature rich, it still 
lacks the feature we needed to make it secure (1) and stable (2). We 
ended up using Shiro as a convenient library with all integration points 
with Wicket written ourselves. We also needed to extend LDAP integration 
to get roles/permissions and override Shiro's idea of configuration (it 
didn't match our way of getting properties files).


(1) forget an annotation and your page is visible, we turned that around
(2) the annotations are based on Strings, we like Enums better

Kind regards,
Erik.

Re: Efficiency of 1.5 MountMapper weighted/matching algorithm

2011-10-18 Thread Erik van Oosten

 I realize it may not be a hotspot but, intuitively at least, it sounds like 
 your new caching improvement will help reduce CPU load. It should also reduce 
 the workload of the garbage collector by not having, in the above example, 
 2800 objects allocated and then dereferenced with every page render.


Don't trust intuition, measure. CPUs and garbage collectors behave different 
then you might think.

Introducing caching means introducing thread collaboration. Any synchronisation 
on modern cpus quickly take more time then any business processing you can 
program. In addition, short lived object cost nothing. The gc can easily handle 
millions per second.

In other words: don't add caching unless you are willing to measure the 
throughput gains (on the intended target systems).

Regards,
 Erik.

 Topicus' (Martijn's daily job) biggest application have ~ 700 mounted
 pages and this code is not a hotspot for them, that's why no one spend
 time on optimizing it so far.
 
 Wow that's big! If you had a variety of main and side bar menus on each page 
 that had links to say 40 or so Bookmarkable pages that would mean each page 
 render would result in building 40 weight/mount pair collections, each with 
 700 entries - and then throwing them away after each bookmarkable page link 
 has been created.

Its not @literal that removes the linebreaks. If you combine it with

Re: [OT] Need Feedback from WicketForge users (IDEA plugin).

2010-12-14 Thread Erik van Oosten

Hi Minas,

Providing code completion for component id's would be great! In particular in 
the java code, slightly less so in markup.


Warnings for unknown component id's in java code would also be a very nice 
feature! It would probably be useful to be able to suppress the warning with a 
comment or annotation. Warnings in the markup are less useful as I often create 
components that infer their component id at run-time from another component. I'd 
hate to have warning suppressing comments in the markup.


Regards,
Erik.


PS. I don't find this OT at all! Anything that helps (many) Wicket developers, 
should be welcome on this list.

Re: UrlRewrite rule and Wicket

Hi Krzysztof,

Sorry to hear that, I must admit I never thought of testing this with forms. I 
just assumed that the form would have a wicket generated URL and that from that 
point on it would work the normal way.

Thank you Erik, the idea is nice, but it does not work ;)

I wanted to implement my own ~ Root Mounting Strategy just when I've
got your email. The idea with overriding getRequestPath sounds good, I
was afraid that I will need to implement my own RequestCycle with
custom logic replacing path.startWith(mountPath()) part.

Unfortunately your solution doesn't seem to play well with forms. When
using the RootWebRequestProcessor pages using HybridUrlCodingStrategy
work on first get request, but after button submit they are redirected
to ?wicket:... page and the state of the page is lost (all values of
fields, no validation errors). I have no idea why it works like that
and does it breaks other strategies.

ps. I had to add
configuration
   webAppConfig
contextPath//contextPath
   /webAppConfig
/configuration
to the POM to make the example run properly with jetty:run. The
default configuration mount the app on /wicket-rootmount-demo so most
of the links does not work.

Hi,

We have existing urls in a form:

/long,and,complex,title,id/new_opinion
/long,and,complex,title,id/something

or sometimes

/long,title/id/new_opinion

The links like /long,and,complex,title are managed by fast and
scalable view, and are stateless. Now we are using Wicket in the same
war. It is mounted to /cms.

We are trying to replace forms, that are pure evil in the first
technology with wicket based forms. But we need to keep the links
untouched.

So I created  UrlRewrite (http://www.tuckey.org/urlrewrite/) rules:

urlrewrite use-query-string=true

rule
from^/(.*),(\d+)/new_opinion$/from
to/cms/new_opinion/id/$2/url/$1/to
/rule

rule
from^/(\?wicket.*)/from
to/cms/$1/to
/rule
...


I have a wicket page - that is mounted on /new_opinion with enhanced
HybridUrlCodingStrategy with:
- redirectOnBookmarkableRequest = false

First rule forwards the request to proper place. Wicket gets the
correct requestUri and all the stuff. But the rule does not work if we
have redirectOnBookmarkableRequest = true because Wicket constructs
wrong urls in ServletWebRequest.getRelativePathPrefixToWicketHandler :

if (!Strings.isEmpty(forwardUrl))
{
// If this is an error page, this will be /mount or
/?wicket:foo
relativeUrl = forwardUrl.substring(1);
relativeUrl =
relativeUrl.substring(filterPath.length());
}

before this fragment Wicket has correct link, after this we get:
g,and,complex,title,id/new_opinion, or errors (sometimes the link is
shorter and I get array index out of bounds). If method does not throw
exception it returns wrong number of ../ . Unfortunately
redirectOnBookmarkableRequest = false does not solve the problem as
the second rule catches Wicket that are redirected if they hit
bookmarkable page. So this fragment need to be fixed in order to have
working bookmarkable links with UrlRewrite.

My temporary workaround is custom delegating WebRequest with small hack:

public String getRelativePathPrefixToWicketHandler() {
HttpServletRequest httpRequest = getHttpServletRequest();

String forwardUrl =
(String)httpRequest.getAttribute(javax.servlet.forward.servlet_path);
final String filterPath =
(String)httpRequest.getAttribute(WicketFilter.FILTER_PATH_ATTR);

if (!Strings.isEmpty(forwardUrl))
{
int count = forwardUrl.split(/).length;

String string = ;

for (int i = 1; icount; i++) {
string += ../;
}

return string + filterPath;
}else {
return
wrappedReqest.getRelativePathPrefixToWicketHandler();
}
}

I guess it will not work in all cases though...

If there is a different way of doing url rewriting? If not, I consider
it a bug in Wicket.

I have seen an application (not mine!) fail horribly and costly on the second

The problem with getting an object from the session and passing the reference to 
a (Compound)PropertyModel is that the natural assumption, the session object is 
updated too, is wrong.
So this is exactly the same problem as keeping a reference to the session 
itself, only now restricted to less data.

made.

Would anyone be interested in replacing the misnamed
and incomplete XHTML DTD used by the Wicket project
with a modular XHTML DTD that had its own Wicket
module? This could be used to validate Wicket-ised
documents. I'm versed in building modular DTDs using
the W3C toolkit. (I note WICKET-693 exists) and can
also flatten the DTD to a single file using a tool I have.

I'd be willing to supply that DTD if someone could provide
documentation on the extant wicket elements and
attributes, and where in the document model they are
permitted.

If this is something properly directed at the Wicket dev
list let me know and I'll resend it there (I'm not currently
a member of that list). Or if this isn't a priority for the
project (it may not be if well-formed XML is sufficient
during dev) I'll drop the issue.

Thanks,

be a bunch of links somewhere that give starting points for someone to 
understand the project. E.g. links to important classes, important 
examples. Either an architecture overview or a small programming guide 
would be great too of course :)

Today we officially announced our project to provide a Wicket-DB4O-Scala
web application stack:

http://sustainablesoftware.com.au/blog/?p=77

I’m pleased to announce a new web application framework, called Granite,
and an associated set of reusable libraries, called Uniscala. Please note
that this is a work in progress: we are not announcing a release yet, or
even a beta. A number people have started asking about the project, and
so I felt it would be helpful to let the wider world know what is going
on.

Granite is a lightweight framework for the rapid development of web
applications. It is based on the very cool and richly featured Apache
Wicket web framework. Granite uses an embedded object database that
avoids the need for SQL or Object-Relational Mappers (ORMs), and, in the
Wicket tradition, is proud of, if not smug about, its distinct lack of
external XML configuration files.

Re: A bug in CryptedUrlWebRequestCodingStrategy

Bjorn,

Please open a Jira issue so that the Wicket core team can track this issue.

Op 15-09-10 11:24, Bjorn S schreef:

Wicket version: 1.4.9 (rolled back due to AJAX problems in later release)

I've detected some odd behaviour with CryptedUrlWebRequestCodingStrategy,
specifically CryptedUrlWebRequestCodingStrategy.DecodedUrlRequest;

When using a QueryStringStrategy for mounting a page and passing certain
specific strings I was getting them back with characters missing. It appears
that CryptedUrlWebRequestCodingStrategy performs double-decoding.


We have a search system which uses + as a means of denoting requirements,
this is what happened;
When entering a search string like car +red it was correctly encoded to
car+%2Bred and passed along.

When decoding I saw that this became car +red and then was decoded again
to car  red [note double space].

I fixed this by extending CryptedUrlWebRequestCodingStrategy, overloading
the decode method and implementing my own copy of DecodedUrlRequest where I
removed the following line from the constructor;
decodedParamReplacement =
WicketURLDecoder.QUERY_INSTANCE.decode(decodedParamReplacement);

This seems to have fixed our problem though I won't guarantee that it hasn't
introduced new ones.

Hope this can get a better resolution.

Bjørn Soldal

Hi,


I am experimenting a bit with page expiry. One solution that works is to
remove the page from the pagemap in the submit of a form. However, removing
the page from the pagemap in the onAfterRender() of a page does not seem to
work. In fact, I see the same page id and version being rendered every
time.  Is this the way it should be? Is there another generic callback in a
wicket page in which I could remove the page from the pagemap to expire it?
What makes the form's onSubmit() special?

Alternatively, I am considering to use a strategy whereby I set an expired
flag on form submit and then in the onBeforeRender() use setResponsePage()
to delegate to a specific page providing also a specific message. That would
allow total control on form submit. Would that strategy work?

Hi Erik,

Non-bookmarkable links either start with /resources or take the form

You could indeed manage that by creating your own RequestCodingStrategy,

tweak too much. In Wicket 1.5 it is probably going to be a lot easier.

Next, I want to make sure that requests for the servlet are forwarded to the

doing this by specifying a number of ignored paths. But, how do I now which

I can create mounts for all bookmarkable pages but how can I control the

My page code constructors:

This page is called to separete ways:

1 - setResponsePage(DeliverySecure.class, new PageParameters(secure=on));

2-  setResponsePage(new DeliverySecure(deliveryInfo));


When i call the DeliverySecure page with approach 1, i get a url with the

surely because it treats the page as bookmarkable.

But with the 2. approach i get a url like: ...wicket:interface=:7

Can i somehow force wicket to add the browser parametersecure=on, when

If so how would i achieve that, even though i want load the page with the

Re: Wicket Sessions and Load Balancing

2010-07-02 Thread Erik van Oosten

Steven,

Have you tried to enforce creation of a session on the home page?
A WebSession.get().bind() in the homepage will do the trick.

This only makes a difference when your homepage is stateless.

Regards,
Erik.



2010/7/1 Steven Haineslyg...@yahoo.com

My guess is that when the homepage is loaded that Wicket provides a new
jsessionid (I sometimes see it coming in the submission url) but then the
user
is directed to another server on the next request, and because the user
does not
yet have a JSESSIONID cookie, but does have the jsessionid in the URL, the
Wicket instance that receives the request searches and cannot find the
session
id and marks the page as expired. The next request then populates the
browser's
cookie and the sticky session works.This is just a theory, but it would
explain
the behavior.

Re: ResourceStreamLocator and mvn resource:resource copying resources in the right directory

2010-06-19 Thread Erik van Oosten

Hi Bernard,

We are using absolute URLs in one application (http://tipspot.com) that 
does not use the wicket ajax library, only javascript (based on jquery) 
written by the frontend developer. One of the things we do there is 
filling popups through ajax requests. As most of that information is 
completely stateless, we use a wicket page to produce the html 
fragments. The URL depth and path of the original page (containing the 
popup), and the page that is pasted into the popup, almost never 
matches. This is a problem for linking to other pages. I found it easy 
to make this problem go away by making all URLs absolute.


I did not look at RelativePathPrefixHandler as I was unaware of its 
existence. I am also not certain that any relative schema would be able 
to solve the problem cleanly/easily. Secondly having absolute paths is a 
non-issue for this application.


Regards,
Erik.

Why are you using absolute URLS?

Are you using absolute URLs to support editing in the web directory,
with a directory structure the same as the java package structure,
without breaking images?

Then it would look like you have found a different solution for the
same problem. Interesting. Both solutions require only small changes.
Have you tried to patch RelativePathPrefixHandler? With that change,
you would no longer be restricted to absolute paths.

If you use a more domain-driven approach, you don't need services as

them via Spring's @Configurable/@Autowire support.  So, you can move a

Re: URL Encoding strategy

2010-04-09 Thread Erik van Oosten

Hi Alex,

I am not sure it is a good idea to include this code in Wicket core (or 
extension). It will make Wicket's URL handling even more nontransparent 
then it already is. For well tested applications you can use the 
workaround, but I'd hate to maintain this code for each and every corner 
case, especially knowing that Wicket 1.5 will thoroughly improve URL 
handling.

Re: InMethod Grid: resizing rowcount

2010-03-16 Thread Erik van Oosten

I can confirm this. It took me a few days of debugging before I found out :(

Another solution is to just replace the inmethod grid with a freshly 
created instance after data changes. You can share the DataSource, and 
you may have to copy over the set of selected items.


Regards,
   Erik.


Pointbreak wrote:

...
Ok thanks for your help. The problem is that inmethod 's call to
IDataSource.query() asks for the rows upto the last known total row
count. In your case that probably does not matter, since you just return
an iterator over the entire datasource, and update the rowcount
accordingly. I work with very large datasources, and unknown rowcounts.
I can workaround this issue by providing the page-size to my datasource,
so that I can fix the IQuery.getCount() asked by inmethod. Not a nice
solution, but will work for now.

Re: Questions about how wicket serialization works

2010-02-22 Thread Erik van Oosten
This has been discussed before (of course) and this is on purpose. If 
you reload old pages your users will probably wonder what's going on 
(they are not used to this behavior), and secondly there is a 
performance hit with no business benefit.


However, you should feel free to change these defaults (by overriding 
setHeaders) for cases where another setting is more appropriate.

   Erik.

Re: Questions about how wicket serialization works

2010-02-21 Thread Erik van Oosten

Answers below...

David Chang wrote:
I am reading the book Wicket in Action. Page 88 about serializing models says: 


At the end of the request, after the markup has been sent to the browser, Wicket 
stores the page, component hierarchy, and associated models (the state) in the page 
store.

Does Wicket stores the page means Wicket stores all the page content (markup plus Wicket-inserted content) sent to the the browser? 
  
No, only the serialized form of the page hierarchy is stored. From this 
all other content can be reloaded (note: markup is only read once and 
cached when in production mode).



I did an experiement in which there are two clock pages with dynamtic models 
(same java class and markup, but differnet class/file names). Clicking on a 
link goes to the second clock page. When I click IE Back button to go back to 
the first clock page, it always shows the current date/time. How so? Why not 
showing the previous date/time when the first clock page was loaded?
  

When you press the back button, you'll see whatever the browser has cached.

My understanding is that when a page is refreshed, each Wicket componet on a 
page calls its getObject to update content. Does the Back button get the 
getObject method called too?
  
After using the back button, reload the page, and you'll get the 
re-rendered content.

What did I miss?

Thanks, David

Throwing a RestartResponseException will not redirect but restart the

 setRedirect(true)

But I doubt it will work for you; when you have an error page without

Re: setResponsePage in the beggining of a constructor does not work

2010-02-04 Thread Erik van Oosten
In Wicket it usually helps to look at the classes that are near in the 
class hierarchy. In this case RestartResponseException extends from 
AbstractRestartResponseException. Another subclass of 
AbstractRestartResponseException is RedirectToUrlException, which does 
exactly what you ask.


Regards,
   Erik.

Chris Colman wrote:

Could I use RestartResponseException to redirect to a URL instead of a 
bookmarkable page?

My problem is that all of my pages require a parameter (even the home page but that's 
fine because the Tomcat container server.xml configures the appropriate redirection for 
me - users never have to enter the parameters in the address bar) but the Expired 
Page page contains a link that does not contain any parameters.

When a session expires the page that appears attempts to go to the 'home' page without 
any parameters. If I could either change the expired page's link or do a redirect in the 
home page's constructor that redirect's to / then this would work fine.

Unfortunately the RestartResponseException seems to only want to redirect to bookmarkable 
pages. Is there an alternative I could use to redirect to the / URL?

bounded to title two levels deeper in hierarchy precisely defined in 
lower most level (top-down should use the last found, shouldn't it?).

The idea of Wicket i18n is that when you use a component, you can

To solve this you'll need to use a more fine-grained name for the

This page has inside an UserAddPanel with form with following

for markup:

wicket:panel

The name and other labels are generated fine (no reason not to) but 
the title is set to User's Home which is not desired. I would 
understood this behavior if I hadn't defined such 'fine-grained'

Is there a way to achieve behavior which I described or do I have to

There is no hook in Wicket to stop. Wicket normally starts and ends with

undeploying the web-app. You'll need to find hooks in your serlvet

itself (that is suicide)?

Re: URL Rewriting in Wicket

2009-12-14 Thread Erik van Oosten
Actually, you should override the WebRequestProcessor and return a 
custom RequestCodingStrategy from there. The custom 
RequestCodingStrategy would extend one of the default implementation and 
override urlCodingStrategyForPath and getRequestPath.

Erik.

Hello,

I would like to do a simple URL rewriting in my application: All requests
containing a given path (e.g., a /x/...) should be filtered and redirected
accordingly.

In other words, for a request to http://www.example.com/x/something I want
to do a database lookup based on the value of something and then redirect
the user to the appropriate wicket page.

What is the recommended way to do this in wicket? Make a hook into the
WebApplication.newRequestCycle() method?

thanks for your help,

Re: Howto test redirect to non-wicket base page

2009-10-12 Thread Erik van Oosten

Per,

You can also throw a RestartResponseException or a subclass thereof. 
That is the recommended way within a constructor anyway. For you it 
would be RedirectToUrlException (or something like that).

Erik.

Wicketstuff core 1.4.0 release preparations

2009-08-13 Thread Erik van Oosten

Hi Jeremy,

I am afraid I do not understand what to do. I set out to test the 
yui-parent module:


I can confirm that /yui-parent/ builds fine (with +mvn install+). Yeah!

However, +mvn release:prepare -DdryRun=true+ executed in the yui-parent 
sub-directory just downloads a yui snapshot instead of compiling it 
localy. Running it one directory up fails because prepare:release does 
not accept diffs with the SCM and I changed the wicketstuff-code pom (I 
commented out all modules except for yui-parent).


What else can I do? Or must one do the whole thing at once?

BTW, should wicketstuff-core not change from 1.4-SNAPSHOT to 1.4.0-SNAPSHOT?

Regards,
Erik.

Re: Wicketstuff releases?

2009-08-12 Thread Erik van Oosten

Maarten,

 AFAIK wicketstuff-core trunk is compatible with wicket 1.4.0

Yes, I know. But my client is not really happy about using trunk/snapshots
in a production system. And frankly, neither am I. I love snapshot
releases, but if I can prevent the extra steps needed to use them in
production I would.

 Side note:  I don't see the version of wicket-stuff has to match exactly
 with version of wicket ?
 Suppose someone releases wicketstuff-core-1.4.0 today, and tomorrow some
 bugs are fixed in wicketstuff-core, then we can't release these bug-fixes
 until wicket 1.4.1 is out ?

I agree. Its just that right now there is no release at all.
As soon as there are more releases of the wicketstuff-core projects and/or
wicket, it makes sense to start a compatibility matrix.

BTW, I don't really care if wicketstuff-core is completely 100% stable, it
will never be. Promoting every first snapshot of the month to a release is
good enough for me.

Regards,
Erik.

Don't you ever re-use a component! Sharing models/behaviors is fine, sharing
components is not.



Thanks, Erik, but I'm pretty sure we're talking about different things.
I'm just using components on a page and changing the data.
(Reusing the form *over time*.)

I have

Page
   DropDownChoice
   Form
  Fields

When an entity is selected with the DDC, the
form is made visible and filled with the model/data
of the entity.  When a save button is hit the form
is hidden and the DDC reset (Choose one...).

You're not saying the Form should be discarded and rebuilt,
are you?

Maybe the thread is wrongly written, yes but a servlet CAN read a

Hi,

I have recently upgraded my project and I did find these changes:
- the first parameter of
org.apache.wicket.markup.html.tree.LinkTree#onNodeLinkClicked has been
changed from TreeNode to Object, so if you had override this method, 
you

need to change the parametertype.
- localization messages for validations works only in
form.component.validatorType=message format, the
component.validatorType=message format isn't working anymore (but 
this could

be change for final release - for further infos see:
https://issues.apache.org/jira/browse/WICKET-2350 )

Besides this, I found in WebApplication#getConfigurationType a FIXME

context-param) should be changed from configuration to
wicket.configuration in final 1.4 release. (See:

//Also many old component has been genericized, a list of these

But since you're not posting to the server but to some other script, why 
bother with using Wicket components? Just use the raw html, and if you 
must use Label and WebMarkupContainer to manipulate the html.

I have written an wicket page that collects some user input and 
calculates values. These values need to be sent to an external python 
script that does something with this data and renders a results page. 
This almost works fine but wicket messes up my form. In the HTML 
template I have specified my form like this:


form method=post action=some_url
input type=text class=field wicket:id=proteinId 
name=protein_id /

input type=submit class=button value=Go! /
/form

but when wicket renders the page it creates this:

form method=post action=some_url
input type=text class=field wicket:id=proteinId 
name=mutantPredictionSubmitPanel:proteinId value=adrb2_human/

input type=submit class=button value=Go! /
/form

The difference is in the name of proteinId value being rewritten from 
protein_id to mutantPredictionSubmitPanel:proteinId, and this 
causes the python script at the other end to choke.


Is there a way to disable the rewriting of the name attribute, or 
specify my own name?

Hi,

same URL:


e...@oostblok:~/projects/wicketstuff$ svn co

svn: Repository moved temporarily to

Accessing the repo with FF is no problem.

Am I doing something wrong?

Re: Caching a resource on the browser side

2009-08-04 Thread Erik van Oosten
.

As the files are users specific (and determined with data from the
session), we went for some page delivering the content like this :
 public AMChartDataProviderPage(final PageParameters parameters)
   {
   Object object = parameters.get(DATA_KEY);
   if ((object == null) || !(object instanceof String) ||
.equals(object))
   {
   throw new IllegalStateException(Expected parameter  +
DATA_KEY +  not provided or empty);
   }
   String dataId = (String) object;
   ByteArrayResource resourceStream;
   try
   {
   resourceStream = new ByteArrayResource(text/csv,
IOHelper.getResourceAsByteArray(dataId + .csv));
   }
   catch (IOException e)
   {
   throw ExceptionHelper.wrap(e);
   }
   getRequestCycle().setRequestTarget(new
ResourceStreamRequestTarget(resourceStream.getResourceStream()));
   }

However, I don't manage to get this resource to be cached on the user
browser side, despite the resource being cacheable. From what I've
seen, setHeaders() in WebResource is never called... Neither did I
manage to set them myself (on the page they're never called neither...
and the request cycle has no webresponse on which to define the
header).

Any clue ?

thanks in advance

Re: Stateless login form?

Ah, I get it. Yes, you are right too, just never got around rewriting

Try clicking this link with a new browser that does not have a session

This is what you would get if your browser loaded the page from cache
(or if you let it wait until the session invalidates). Does not look
professional and it is totaly unnecessary, in my opinnion. It should
be possible to handle forms on virgin (=no state bound yet)

Try this in a method of your WebSession subclass:

   ((WebRequest) 
RequestCycle.get().getRequest()).getHttpServletRequest().getSession().invalidate();
   // Bind forces a connect of the current Wicket session to the 
new HTTP session.

   bind();

I've stumbled upon the  Session.replaceSession()  method which, 
according to the javadoc, should just exactly do that.
But when I call this method, nothing happens. The same session 
continues to be used and no new session is being created at all?!


I've got it to work by using:

   Session newSession = getApplication().newSession(getRequest(), 
getResponse());

   newSession.setLocale(getSession().getLocale());
   getSession().invalidateNow();
   Session.unset();
   newSession.replaceSession();

But I think there must be something easier... ???!

Re: Questions about Wicket sessions

2009-07-26 Thread Erik van Oosten

David,

Please note Sessions are not thread-safe in Wicket context means that 
the Session /object/ is not thread-safe. Note that requests that fall 
within a session (except for resources) are handled serially. Only when 
you use session clustering this guarantee can not be made.


1. It depends on the browser. All modern browsers will make it one session.

2. Same answer.

3. No. Wicket does this for you.

Regarding your question on session storage: you'll be hard pressed to 
find a more performant solution to Wicket's http session disk store. 
Perhaps that memory solutions would work better.


Regards,
   Erik.


David Chang wrote:

2. If I start IE or FF in another window, visitor activities on the same Wicket

3. If dirty() is called within a method of custom session object, then it is 
the developer's responsibility to implement dirty() to synchronize with other

Re: Spring and Wicket - is it worth it?

2009-07-23 Thread Erik van Oosten

Spring gives flexibility in your services layer (whatever you call it).
Making things transactional, adding memoization, talking to remote
interfaces, configuring Hibernate and JMX beans, all that kind of stuff is
easy with Spring and often unbelievably hard without.

As said, Spring has no value in a Wicket application with the exception of
calling out to the service layer. This is where the @SpringBean comes in
handy.

Erik.

Re: Updating an inmethod grid, looking for hints

2009-07-23 Thread Erik van Oosten

Hi Matej,

I finally found the bug.

When you are using a DefaultDataGrid it adds a PagingToolbar. PagingToolbar
overrides isVisible. In isVisible the total row count is determined, this
will cache the query result for this request. However, isVisible is called
/before/ the ajax listener is called. Therefore any changes to the grid
(like rowCount) are not used.

Erik van Oosten wrote:
 
 Hi,
 
 How can I trigger an inmethod grid to do a /complete/ update of itself?
 
 The only thing that I see is markAllDirty(). That will update the items 
 currently in the list, but it will /not/ get new items from the data 
 provider.
 
 I researched the code for quite some time but I must have been looking 
 at the wrong parts as I found no hook to get this done. The most I could 
 do was call detach() on Body, one of the inner classes of a grid. But on 
 screen, that would only update the number of items in the lower toolbar, 
 not the items in the grid themselves.
 
 More ideas?
 
 Ideally, imho, the grid should respond to modelChanged(). But I have 
 still no clue what should be in that method.

 Erik.

From the first glance it looks just like a mix of two strategies but it

parameters delimited by slashes and some of them have names omitted.
Original Mixed strategy operates with regular parameters syntax. I believe
it would take some hours to study what strategies do internally and
implement and test mixed solution. I hoped someone have already tried that.

Unfortunately I didn't find anything by google and nabble so I posted the

Re: intercept security check in wicket-auth-roles

You don't have to use the spring xml config files to use Sprint

There is a small catch, you'll need to know something about Spring 
callbacks. These are some interface that Spring will automatically call. 
These are: InitializingBean, BeanNameAware, BeanFactoryAware and 
ApplicationContextAware. Hopefully Spring Security does not depend on them.


But there are other options like jsecurity and lots of options on
