Re: Wicket for Hybrid App

[nazeem]

My App is not static, I intend build some thing like this..

Phone gap + html + css + JS  >> Bundled as Android App / iPhone App

To start with need to be online, connect to the server using REST,
synchronize the data and store in local db storage via phone gap api's. 

Now when offline, the App uses local storage DB and when connected to
internet it sends all local stored or updated info to server  via REST and
pulls latest info from server. 

Do you see any issue with this ? I would love to use Wicket for the front
end, but not yet.. Can wicket generate client side stubs like DWR does ?

Wow, I didn't know Tomcat had that feature. That could be the solution, I

Re: Proper resource versioning

Hi Dan,

Thanks for sharing this!

Hi, Bertrand. I don't have all your answers, but I can share my experience.

First, when you say you serve files out of webapp folder, do you mean
you're not using any ResourceReference? Just absolute paths from markup? I
think improving that is the first thing to do. You need to process resource
references in Java so you can introduce versions, CDN base URLs, etc.

To answer your question, here's what I use to access my webapp resources:
-ContextImage which uses context-relative urls
-RelativePathPrefixHandler which handles hrefs in the markup and makes 
them context-relative

-UrlResourceReference with, again, context-relative urls


The main caching problem we had was that after upgrades, some clients had
the old CSS cached and the site looked funky for them. So we went through
and made sure all CSS is served through PackageResourceReferences. Wicket's
default versioning strategy then did its magic and that complaint stopped.

With respect to @import, we have many @imports in our source LESS, but by
the time it's being served, the CSS is flat. So versioning that is enough.
It's possible but I think far less likely that this kind of caching problem
will happen for images and fonts. Direct references to these from our
application still go through ResourceReferences just so they can be served
from CDN, but we don't worry about relative-path includes from CSS.

What does LESS mean in the first line of the paragraph above?

Do you do anything special to "flatten" the css files?

So, to not "worry about relative-path includes from CSS", you must make 
the images non-versioned, correct? Do you do this using 
ResourceReferences and IStaticCacheableResource#isCachingEnabled() ?


If you use ResourceRefenrecs, does that mean that all your assets (css, 
js, images,...) are stored along with the java class files (i.e. 
src/main/resources in Maven terms) ?


Thanks again!

question about page variable in AjaxRequestHandler

[Andrew Geery]

I just wanted to confirm that add(Component...) in AjaxRequestHandler
will only work with (i.e., refresh) components that are on the same
page as the page associated with the AjaxRequestHandler.

I had a case where the content of a ModalWindow was a WebPage.  In the
modal window, there was an AjaxLink where I was trying to update a
component on the underlying page in the onSubmit method using the
AjaxRequestHandler object (not directly, in an event handler on the
underlying page).  However, this didn't work and I noticed that the
AjaxRequestHandler object referred to the WebPage in the modal window,
not the page from which the modal was launched.  If I change from
using a page in the modal to using a panel (and thus the
AjaxRequestHandler.page refers to the underlying page), the underlying
page gets properly updated.

If it is true that an AjaxRequestHandler can only be used to update
components on the page it is associated with, would it make sense to
add a warning to either AjaxjRequestHandler or AbstractAjaxResponse if
a component is added which is not on the page associated with the
AjaxRequestHander or AbstractAjaxResponse?

Thanks

Events: Atmosphere vs. Guava vs Wicket native

[yarnish]

Hey guys

I'm making a Wicket 6 application that will use Atmosphere for server push
events. I am also planning to use events to communicate between wicket
components (for any messages between components not defined in the same
class) and possibly to use events/observers for internal application
business logic.

One of the guides/examples on using Atmosphere talket about using Guava for
application events and just using Atmosphere for server push events to the
client. I can understand if you want to keep a loose coupling between a
wicket front end and your business logic, but it seems to me that Atmosphere
could be used for events, even in the case that you wanted to use another
front-end framework.

Are there any good arguments for not just using Atmosphere events throughout
the application, completely avoiding Wicket and Guava events? Are there
significants advantages (for instance performance related) to using wicket
native events for the component-component messaging? Is there a consensus
about what is best-practice, or is it mainly a matter of taste.

Looking forward to hearing your thoughts on the matter. Thanks in advance

Jarnis

I'm not sure why that would be.  All our pages are launched from the
same menu, my new one included.  They all load their springbeans using
@SpringBean, as does the panel I am re-using which I "new"ed from the
wicket constructor just like everyone else does.  Wicket shouldn't
have been launched using any bootstrap classloader, nor would the
spring context I should think.  I will construct a test of this in the
morning.

Well, this is a project where getting approval in the schedule to do
pretty much ANYTHING is largely mandatory.  And approvers don't put a
high priority on upgrading for the sake of upgrading.  They usually
have to be given some compelling specific reason...the new version
fixes a bug that is hurting us, the new version performs better, etc.
No other pages are having this problem, so I don't know if this would
qualify.  I certainly will run it up the flagpole.  But I wouldn't
hold my breath.

Proper resource versioning

[Bertrand Guay-Paquet]

Hello,

I'm trying to figure out the optimal way to deal with caching and out of 
date resources and can't really find which methodology to adopt.


Considering that:
a) css and js files are only accessed from web pages
b) image files are accessed from web pages and from email clients (links 
stored for a long time)

c) image files are referenced from css (e.g. background-image url)
d) font files are accessed from web pages and maybe eventually from 
email clients
e) some css files currently use "@import" statements to include other 
css files (this could be removed if needed)
f) css, js, fonts and images currently are all located in the webapp 
folder (i.e. I wasn't able to access them with PackageResourceReference)
g) whatever the approach, it needs to be compatible with eventual usage 
of CDN services


Questions:
1- Which files should be versioned?
2- Should they be versioned using Wicket's ResourceReferences?
3- Are there other considerations I haven't thought about?
4- Which successful approaches are in use now by other Wicker users?

Thanks for your insight!

Regards,
Bertrand

Re: Exception with validator

[Sven Meier]

LookupService is probably coming from another class loader than the 
Wicket classes.


Any particular reason, why you're using Wicket 1.4.x?
The code to resolve the class on deserialization has been improved with 
Wicket 1.5.x to use the current thread's context class loader.

Re: Exception with validator

[Entropy]

I meant to also mention that while other pages in the app use this panel and
do NOT have this problem, those other pages do not have an extension of that
class.  I know some annotations do not inherit, but again, the lookupService
is loaded at first.

Exception with validator

[Entropy]

Form and button works fine without my validator (sounds similar to my last
message but this is the next problem).  Validator puts up message, and
reloads page with error in it on form submit.  But the following exception
appears in my console.  The situation is that a re-usable panel has an
@SpringBean property on it.  There is a an extension of that class that a
panel on my page uses.

The @SpringBean plainly works at first.  The lookupService is set, and works
fine within the reusable panel.  Until I test the error condition.  Then
this happens in the console.

HttpsMapper not Switching to SSL When there is no JsessionId Cookie

[Tim Urberg]

Hi Everyone,

I'm having an issue with HttpsMapper not switching to SSL when there is 
no JSESSIONID cookie.  It's happening with wicket-auth-roles when the 
user goes to the home page, which need authentication.  I have this code 
in my init method in my WebApplication class.


getSecuritySettings().setAuthorizationStrategy(new IAuthorizationStrategy()
{
   @Override
   public  boolean 
isInstantiationAuthorized(Class componentClass)

   {
  if (AuthenticatedWebPage.class.isAssignableFrom(componentClass))
  {
 if (MyAuthenticatedWebSession.get().isSignedIn())
return true;

 throw new RestartResponseAtInterceptPageException(new 
LoginPage());

  }

  return true;
   }

   @Override
   public boolean isActionAuthorized(Component component, Action action)
   {
  return true;
   }
});

HomePage implements AuthenticatedWebPage and LoginPage has the 
@RequireHttps annotation.  This only seems to happen when there is no 
JSESSIONID cookie.  The URL looks like this:


http://localhost:7011/documentation/login;jsessionid=1c9nRTpWGWynRXdX1WKC5ZnSfTNKCydGTdHH83mvfXQZQcQ8fLpx!-1875818450?0

when it should be https://localhost:7012/login.  If I try it a second 
time after the cookie has been created it works fine.  This is not a 
problem when I go straight to http://localhost:7011/login (works fine 
then).  Just wondering if anyone else has this problem.


Thanks,
Tim

Re: Ajax and validators

[Entropy]

Thanks Sven, that was what I needed.  

Just for my learning, why doesn't AjaxLink report the user input?  If it is
not meant to, it doesn't seem to serve a purpose, so I have to assume I did
something wrong there as well.

Re: Free Wicket guide now available!

[Andrea Del Bene]

Hi Martin,

thank you for your kind support. I'm having some difficulty creating a 
patch containing a binary file (the book cover). Any advice or suggestion?

Well done, Andrea!

Create a cover image and we should add your guide to
http://wicket.apache.org/learn/books/
Or just send a patch with the addition -
https://svn.apache.org/repos/asf/wicket/common/site/trunk/learn/books

Dear Wicketers,

You can find it at

Re: how to create a new Session

[Paul Bors]

Ohh, and yes. If a new tab opens while a session is still around isn't that
normal to take over the existing session?

Is like leaving home w/o locking the front door and then expecting to find
it locked when you come back from work.
Set the session time out to a smaller amount of time, like 1 min to solve
that problem.

Re: how to create a new Session

[Paul Bors]

Not even, he already knows is a new session:

"A new user comes and tries to log in (before the
session expires). He would get the same session, wouldn't he? How can I
enforce that he get a new session?"

I advise you only create new sessions after the user authenticates (ie: always
create a new session each time you log in).
Any old versions such as the one left behind because of the closed tab, let
it expire and it would eventually be cleaned up.

Re: Adding a large amount of MarkupContainers into the ListView or RepeatingView

[Paul Bors]

Get rid of your large scroll area and use data tables with 50-100 rows per
page along with a filter panel.
That'll be more like the "wicket developer" way.

As for the fancy infinite scrolling, I would strongly suggest you take the
advise and consider what Martin said about using lazy loading repeaters
with DOM elements being added and removed unless you want to get the all
familiar "This application stopped responding, would you like to terminate
it now" error from Windows whenever you scroll past first few hundred rows
in IE :)

Re: tomcat session replication

[Dan Retzlaff]

Hi, Sauli.

The context of your question is not clear to me. Are you trying to upgrade
a running cluster?

I have not used Nginx, but Apache HTTPD allows you to disable balancer
members from receiving new sessions. Alternatively, Tomcat 7 supports
parallel deployments so theoretically you can upgrade in-place [1]. In any
case, my understanding is that the main risk to abruptly taking a node down
is that the new node won't have users' page history (in DiskDataStore). His
current page and session state will however be available.

Any confirmation or correction of these statements from the community would
be appreciated.

Dan

Re: AjaxLink with image

[Paul Bors]

I take it delete.png is in the same package as SabcActionsPanel.class and
they both are in a jar that's placed on your classpath and end up in your
deployed folder under WEB-INF\lib.

Have you checked the HTML source code of your page after wicket rendered it
on  your page and that your  changed to
something like ?

Try loading that relative SRC in your browser's URL. Can you get to that
image?

Re: Wicket for Hybrid App

[Paul Bors]

I shouldn't say static, I shoud have asked if your app is not depending on
a persistence server side storage?
ie: I would expect my data view to change when I update a filter and a SQL
or some query to run on a remote server.

Re: Serverside caching of IResource's that are expensive to generate

[Pointbreak]

Cool! I took a slightly different route, as explained in a previous
mail. I may try to find some time to see if both implementations could
be merged, but I'll have to check license issues first. What I built is
tightly integrated with Less4J so I'm not so sure merging the two would
make sense for wicket-bootstrap anyway.

I put a few comments inline below. Will try to make some time free later
to have a look at the pull request.

Cheers

You don't need a CssResourceReference for that, any ResourceReference
can be used like that.

Why would you want to have a minified name for your less source file?
Only the output after compilation goes to the client. The compression (I
guess you mean minification) can be handled by Less as well.

Please note that LessSource.URLSource is not threadsafe, your
CacheManager seems to assume that. I went the same route as you, caching
LessSource, but made my own threadsafe LessSource implementation for
that (and also to @imports much much more flexible).

Re: Ajax and validators

[Sven Meier]

Hi,

an ajaxbutton submits the form, see its javadoc.

You probably want to use #setDefaultFormProcessing(false) on your button.

Pull the validator back out and everything works.  So clearly the validator
is in the way, but it shouldn't be...it's not validation time yet!

Question 1: Why would a form validator interfere with an ajaxbutton's event?
It was NOT a submit button.

Then a co-worker suggested I try to use AjaxLink instead of button, but tie
it to a button.  This allows the event in (Hooray!) but now getInput()
returns null.  As if AjaxLink doesn't bring any screen controls other than
itself.

Question 2: Why is AjaxLink making getInput() null?  If there is some other
mechanism to get form data, what is that mechanism?

The AjaxLink code looks like:

add(new AjaxLink("addSelected") {

@Override
public void onClick(AjaxRequestTarget target) {
onAddSelected(target);
}
});

private void onAddSelected(AjaxRequestTarget target) {

Re: Serverside caching of IResource's that are expensive to generate

[Martin Grigorov]

Hi,

At https://github.com/l0rdn1kk0n/wicket-bootstrap/compare/cached-less you
may see the diff between master and cached-less branches.
I still have to discuss the changes with Michael Haitz but your feedback is
welcome too!

LessResourceReference is a specialization of CssResourceReference so it can
be used like:


 @Override
public void renderHead(IHeaderResponse response) {
super.renderHead(response);

response.render(CssHeaderItem.forReference(new
LessResourceReference(HomePage.class, "demo.less")));
}


LessPackageResource is a specialization of CssPackageResource so all that
is valid for CPR is valid for LPR too - compression, minified name, etc.

The real logic is in LessCacheManager that handles the server side caching
for the generated CSS content per Less resource.
As I explained earlier:
- if a request without 'If-Modified-Since' request header is being
processed then the cache manager is being advised
- if there is no CSS content entry in the cache then the Less resource is
compiled on the fly
- if there is CSS entry then it is returned
- if there is 'If-Modified-Since' then it is used by the cache manager to
compare it against the last modification time of the root Less resource and
all imports in it
- if the Less resource is newer then the cache manager returns either the
generated CSS or re-generates a new one if the CSS has been generated is
before the last modification of the Less file(s)

I know this is an old thread but I found it just now when facing a similar
case.
Could you or someone explain more: How do you do this and what load balancer
are you using for this? Do you know would nginx support this?

I would guess that it would be pretty common to have to wait for sessions to
die before starting to install the server but it seems to be pretty hard to
find any concrete examples.

If someone could point me to the right direction, I'd appreciate it.

Re: BgiframeJavaScriptResourceReference in wicket 6.5.0

[Martin Grigorov]

Hi,

You cannot find it because it has never been part of Wicket distro.
It is part of some third party library you use.

Re: Velocity Log

[Martin Grigorov]

Hi,

I see that you cross posted to Tomcat's mailing lists.
Please make sure that you update the thread there with the solution.

Wicket doesn't require Apache Velocity.
Only if you use VelocityPanel from wicket-velocity module in your
application then you need velocity.jar in your classpath.
I guess you don't need it so just remove it from your.war#WEB-INF/lib/
folder.

RE: Velocity Log

[Bruce Pease]

We are running a web application under tomcat using the wicket framework.  A
requirement for Wicket is the velocity libraries.  The velocity framework is
auto loading and writing to a log in the conf directory.  Since it is in use
I am unable to undeploy the web application.  So, I am looking for a way to
turn off the velocity logging.  Previous version of tomcat does not have this
issue (7.0.26).

BgiframeJavaScriptResourceReference in wicket 6.5.0

[iamrakesh]

Hi,

I am trying upgrade wicket library version from 1.4.21 to 6.5.0. I am using
BgiframeJavaScriptResourceReference class and I couldn't find it in the
latest version and couldn't find any text in migration Wiki page!

Is there any replacement for this class?

Rakesh.A

Re: Adding a large amount of MarkupContainers into the ListView or RepeatingView

[vineet semwal]

i was expecting this case too :-) but it's a very unusual usecase for a
*user* but not for wicket developer ,i have an easy(may be stupid) idea for
this,no need of quickview :-) ,show only one repeater's page items  to user
like as usual.., on scroll event just  repaint the repeater's parent
,foreg. with dataview on event

dataview.setcurrentpage(dataview.getcurrentpage()+1) //plus or minus 1
depending on scroll direction
target.add(parent)

that might be the cheapest/baddest way of achieving this usecase :-)

Re: Adding a large amount of MarkupContainers into the ListView or RepeatingView

Hi,

I mean something like
https://github.com/mleibman/SlickGrid/wiki#virtual-rendering - DOM objects
are added and removed while scrolling, thus keeping the DOM tree size small

Re: Mapping by hostname?

[Martin Grigorov]

Hi,

If you are able to extract this info from the HttpServletRequest then you
should be able to do it.

Request req = RequestCycle.get().getRequest();
HttpServletRequest httpReq = ((ServletWebRequest) req).getContainerObject();
httpReq.xyz()

Mapping by hostname?

[Ondrej Zizka]

Hi,

I have one site which uses generic hostnames (subdomains) and shows a 
page based on that.
The mapping is pretty simple, something like .mysite.com would 
load a page of the $stringId object.


Is that achievable with current URL mapping system?
Is there some such? FWICT, the existing mappers only deal with the path 
part.


Thanks,
Ondra

Re: Adding a large amount of MarkupContainers into the ListView or RepeatingView

[vineet semwal]

hi ,
do you mean removing items when you said unloading?
the scroll behavior and navigator that are in the package just do
quickview#addItemsForNextPage()  on event like in this example
https://github.com/vineetsemwal/quickview/blob/master/wicket-quickview-examples/src/main/java/com/aplombee/examples/PageScrollBar.java

somone who doesn't want to maintain state can do

*protected* void onScroll(AjaxRequestTarget target) {
//this removes items but do not update client view
quickView.simpleRemoveAll();
 addItemsForNextPage(quickView);
}

as in this case the state is not maintained hence not good for someone
who wants to use stateful components ..
may be i am just misunderstanding you :-)

Re: Wicket DefaultDataTable - Refresh it on browser back button

[Jayakrishnan R]

Hi Martin,

Thanks for the direction. I finally found the problem. The list of records
( collection ) was assigned to the data provider in the contructor of that
page. So when I press back button, the latest data was not getting
refreshed.

I still need to find a way to push the latest data on to the model.

Thanks
JK

Re: FeedbackPanel Empty on Wizard in 6.5

[Fergal Keating]

FYI,

I couldn't resolve the issue. I had a couple of places with ListView and i
made sure setReuseItems was (true) but that didn't resolve the issue. I
tried removing various panels to track down the issue, but still nothing.
However when i removed the .setRequired on some textboxes the form then
processed and i was already throwing exceptions for invalid data, then
catching exceptions and calling Error(exception.getmessage) <<-- Note
calling error() at this point worked without referring to the sesssion as
long as the form/submit was called.

So i just updated the exceptions to check for null values in the model and
set the error feedback that way.

Fergal.

Re: how to create a new Session

[ravaszroka]

Thanks for the answer. I have however a follow up question.

In a browser there are at least two tabs open. In one of them a user logs in
and instead of logging out (where the session is explicitely invalidated) he
just closes the tab. A new user comes and tries to log in (before the
session expires). He would get the same session, wouldn't he? How can I
enforce that he get a new session?

getSession().bind(); is what you need

the session is shared between the tabs.
session scope means - all requests from an user agent until the session is
invalidated or expire due to inactivity

how to create a new Session

[ravaszroka]

hello.

how can tell the wicket application to create and use a new session for
subsequent requests?
the problem to solve is: 
the session keeps track of userdata. on the login page a new session should
be created and used. 
one solution would be to reset the userdata when i'm on the login page.
however, if in a browser (chrome) i try to log in from 2 different tabs the
session is shared, which obviously is not what i want.

can someone lighten me on the relationship between httpsession and wicket
session. 

thanks.

Re: AjaxLink with image

[Marco Springer]

The Markup is missing somehow but I'd say the following HTML should do the 
trick:

  


Check the log if it isn't complaining that it can't find the "delete.png" file..

Your markup didn't make it and Nabble says your thread cannot be found.

Re: Adding a large amount of MarkupContainers into the ListView or RepeatingView

[Martin Grigorov]

Check https://github.com/vineetsemwal/quickview - a lazy loading repeater.
I'm not sure whether it also unloads items which are no more visible.
