Hi

We were ready to put a new wicket application into production, but after
deploying it it on our pre-production server with Weblogic 8.1 SP5+JRockit, 
we see a really strange and serious problem. 

Initially after deployment, everything works fine, but after refreshing
a page with a DataTable 10-50 times, the toolbar components added to the
DataTable
 (column headers and the paging) disapears! And they disapear on ALL pages
using the DataTable component.

No errors in any logs, and otherwise everything works perfect.

Only re-deploying or restaring the server will make the toolbars come back.


Then we tried to download and deploy the Wicket-examples-1.2.5.war, and it
also fails in the same way,
after refreshing the DataTable Example
 a number of times. Since it is configured as development mode, it does show
an exception instead of the toolbars jst disapering.
 
The exception is below, and indicate that the markup has lost it
references to the toolbars.


We can recreate the problem running WL+JRockit locally from IntelliJ, but
not when a debugger is attached (probably because optimization is then
turned off).


The strange thing is that only the toolbar components fail, and that it
fails only after showing such a page a number of times. 
Also when one page with a DataTable has failed, all the pages in the
application using DataTable component will be in error

Since we are otherwise ready to go into poduction, we really need a
workaround or a fix, 
but changing the application server or JVM will be really difficult because
we are a big company with standardized production servers.


I will be really really thankfull, if someone can solve this problem!

Re: [Wicket-user] Testing Wicket with JMeter

2007-02-21 Thread Flavia Paganelli

Hi!
I've also been making JMeter tests over Wicket applications. I had to 
use the HTTP Cookie Manager.
But still sometimes I found strange behaviour, like it sometimes stopped 
working, I recorded the same test again and it worked.
The problem always appeared with a submit (POST).
Not much help, but...

 Hi 

 Im trying to test an application with jmeter , I keep getting page expired 
 when testing. I have a cookie manager and save jsessionid, are there any 
 thing else I should be aware of in that direction?

 The application are rather simple although there are some ajax calls. The 
 test fails on the first submit with a page expired.. Any ideas on what im 
 doing wrong ? Please ask if you need more information...

Nino,

Wouldn't that leave all of the pages in session?  I.e. you expect to
have 7 pages in history, but 7 points to 8, which points to 9, etc.

 on previous: setresponse(previous);

Yep, it would. This pattern works good for when you have dialogue
style pages (gather some info and then return) that could be accessed
from a number of different pages (so where to navigate back to is
something you want to keep flexible). But the price for the ease is
that you'll keep a reference to the page to get back to thus
preventing it to be garbage collected.

Re: [Wicket-user] Strange Weblogic problem with DataTable - help needed!

Do you think you can isolate the case and have it reproducible in a
test case or quickstart project?

I'm also wondering why you run the application in development mode. It
doesn't run those render checks when you're in production mode.

Re: [Wicket-user] wicket 2.0: setting default locale

Sorry about that, that was a slip. We recently had a change that would
allow you to pin the session's locale in the constructor. Setting the
locale afterwards should have been removed. It's fixed in trunk now.

 hi all,

 any ideas how to set a default locale for sessions (wicket 2.0
 snapshot)? i support only a limited amount of locales in my app and need
 to get some localized data from my database using the sessions locale.

 my first thought was to set the locale in my websession's constructor.
 but it gets overwritten in WebApplication.getSession again


 if (session == null)
 {
 // Create session using session factory
 session = setSessionFactory().newSession(request);
 // Set the client Locale for this session
 session.setLocale(request.getLocale());
 }

 as in the Session class constructor the locale is set anyways, is there
 a special reason to set the locale again right after the creation?

 protected Session(final Application application, Request request)
 {
 this.locale = request.getLocale();
 if (locale == null)
 {
 throw new IllegalArgumentException(Parameter 'locale' must 
 not be null);
 }
 }

 thanks for your help!

Re: [Wicket-user] Dumb question about serialization

If you don't need back button support at all, just have all your pages
(or probably some base page) override isVersioned (or use
setVersioned) and let it return false. Wicket will not record changes
then, and your URLs between what otherwise would have been versions
keep stable.

Also, set IPageSettings#setMaxPageVersions to 1 and it is best to use
the HttpSessionStore.

 cannot be serialized which need to be displayed in a ListView, and
 when I try to modify the contents of the ListView, it causes
 exceptions because it automatically tries to serialize everything
 which I call modelChanging().

 Is there a setting I can change somewhere to run everything in memory?

Yes, it can be reproduced by the wicket examples application from
www.wicket-library.com.

Of cause we run our application in production mode, but the wicket-examples
application
is in development mode when downloaded, so it makes no effect on the error
other than in development mode the below exception is shown instead of the
toolbars just disapering.

Re: [Wicket-user] Strange Weblogic problem with DataTable - help needed!


But did you try with Weblogic 8.1.5+JRockit JVM?

We did not see any problems while developing using Sun JVM.

 Hi

 We were ready to put a new wicket application into production, but after
 deploying it it on our pre-production server with Weblogic
 8.1SP5+JRockit,
 we see a really strange and serious problem.

 Initially after deployment, everything works fine, but after refreshing a
 page with a DataTable 10-50 times, the toolbar components added to the
 DataTable
 (column headers and the paging) disapears! And they disapear on ALL pages
 using the DataTable component.
 No errors in any logs, and otherwise everything works perfect.
 Only re-deploying or restaring the server will make the toolbars come
 back.

 Then we tried to download and deploy the Wicket-examples-1.2.5.war, and
 it
 also fails in the same way, after refreshing the DataTable Example
 a number of times. Since it is configured as development mode, it does
 show an exception instead of the toolbars jst disapering.
 The exception is below, and indicate that the markup has lost it
 references to the toolbars.

 We can recreate the problem running WL+JRockit locally from IntelliJ, but
 not when a debugger is attached (probably because optimization is then
 turned off).

 The strange thing is that only the toolbar components fail, and that it
 fails only after showing such a page a number of times.
 Also when one page with a DataTable has failed, all the pages in the
 application using DataTable component will be in error

 Since we are otherwise ready to go into poduction, we really need a
 workaround or a fix,
 but changing the application server or JVM will be really difficult
 because we are a big company with standardized production servers.

 I will be really really thankfull, if someone can solve this problem!

[Wicket-user] Could this be a bug in Wicket 2?

2007-02-21 Thread Gohan


I've posted this as a reply to another thread but I think it deserves a
thread of its own. 
What happens is that I'd like to show and hide a label by setting switch
between setVisible(true) and setVisible(false) when clicking on a
AjaxFallbackLink. I've wrapped the label inside a WebMarkupContainer to make
this doable. Here is the code:

public BasePage() {
final WebMarkupContainer table = new WebMarkupContainer(this,
tableId);
table.setOutputMarkupId(true);
final Label label = new Label(table, labelId, This is a label);
label.setOutputMarkupId(true);
label.setVisible(false);


new AjaxFallbackLink(this, linkId) {
   private static final long serialVersionUID =
5523627214368899839L;
  @Override
  public void onClick(AjaxRequestTarget target) {
   final boolean visible = label.isVisible();
label.setVisible(!visible);
  target.addComponent(table);
 }
   };
}

When I click on the AjaxFallbackLink the first time everything is fine, the
label (with wicket id labelId) gets visible. But when I click the link
again to make it invisible, I get a NullPointerException when executing
label.setVisible(..). Debugging down into the wicket source code tells me
that the NullPointerException occurs on 327 in class Page, when it tries to
execute versionManager.componentStateChanging(change). However
versionManager is null. Why is this? Is this a bug or am I doing something
wrong?

Thanks

Hmm I had a similar problem with the wicket 2 snapshot yesterday. I deleted

I am however *not* able to reproduce it with Sun jvm and/or when a debugger

Re: [Wicket-user] Strange Weblogic problem with DataTable - help needed!

In production mode, the toolbars disapers after refreshing the page a number
of times.
This means that there are no column headers and no paging lnks.

The difference compared to development mode is that in development mode a
check for unrendred components is performed, so there I get the exception
from
the first post.

 Probably the thing that makes it difficult to use is that by default
 it looks for an xsl in the package of the component the

 So if you have a component foo.bar.MyComp.java you want to transform,
 and it is added to the hierarchy with myId, then it will look for
 foo.bar.myid.xsl to apply for the transform.

 But you can also submit the full path and file name to the
 XsltTransformerBehavior's constructor.

 Other than that, it couldn't be easier to use. Just add(new

Re: [Wicket-user] Dumb question about serialization


What is the default for the maxPageVersions?

   Other than that, it couldn't be easier to use. Just add(new

[Wicket-user] Best practice and use of detachable models


Hi,

I use Hibernate and have got a reasonably sized app working with Wicket.  I
am aware of the concept of detachable models and want to use it effectively
and I have the following questions.  If the information is already there on
the wiki or something - feel free to point me there.  Apologies in advance
for the dumb questions, but I'm sure there is a general consensus that
Wicket models are tricky to understand.

a) If you don't use detachable models, it is ok but the downside is that
when your page is serialized, your models get serialized and this could take
up a lot of memory. Is my understanding correct?

b) In some cases I use new Label(foo, new PropertyModel(fooModel,
foo))); and in some cases I use new Label(foo, fooModel.getFoo()); which
should I stick to or when should I use which?

c) I have a list of objects I got from Hibernate.  Can you provide (or link
to) some simple code that will show me how to install this model on the
parent component, and I mean in detachable mode.  In my case it is just a
WebPage.

d) Now I am iterating using ListView.  How exactly do I initialize the
ListView so that it uses the installed detachable model?

e) While rendering each row of the ListView, how do I initialize Labels so
that they in turn get the right chunk of the detachable model?

f) And suppose I have a Label that has to be derived by say some string
concatenation or formula and OGNL notation will not work.  Will new
Label(foo, fooModel.getFoo() + bar)kind of hardcoding conflict in some
subtle way with the concept of detachable models?

Thanks,

Peter.

[Wicket-user] wicket:component, container, pseudo, et al

2007-02-21 Thread Scott Swank

All of the above tags were disparaged in the wicket:component vote.
Are any other tags all but deprecated?  The following are all clearly
standard tags.

   wicket:border
   wicket:child
   wicket:extend
   wicket:message
   wicket:panel

What about

   wicket:link

In particular, which tags (apart from component, container  pseudo)
would I be best off avoiding?

Thank you,
Scott

what can be tricky about interface IModelT { T getObject(); void
setObject(T t); } ? :)

there is a great wiki page on models that explains all this stuff in detail.

a) If you don't use detachable models, it is ok but the downside is that

when your page is serialized, your models get serialized and this could take
up a lot of memory. Is my understanding correct?



yes. generally you want to keep your session as small as possible. generally
there are no reasons to stick things in there that can be loaded from the
db.

b) In some cases I use new Label(foo, new PropertyModel(fooModel,

foo))); and in some cases I use new Label(foo, fooModel.getFoo());
which should I stick to or when should I use which?



if you dont mind the object put in session then you can do foomodel.getfoo()
(like if its something simple like a string)

c) I have a list of objects I got from Hibernate.  Can you provide (or link

to) some simple code that will show me how to install this model on the
parent component, and I mean in detachable mode.  In my case it is just a
WebPage.



add(new listview(list, new loadabledetachablemodel() {
  public object load() { return
getsession().createcriteria(user.class).list();
}
}

thats all there is to it. consider this:

public class entitymodel extends loadabledetachablemodel {
 private final Class clazz;
 private final Serializable id;

 public entitymodel(Class clazz, Serializable id) {
this.clazz=clazz; this.id=id;
 }

 public object load() { return getsession().get(clazz, id); }
}

the above model is a generalized hibernate entity model. you can do thigs
like

setresponsepage(new ViewUserPage(new entitymodel(user.class, 15)));

this model will load the user when getobject() is called, and keep it in
memory during the request. once the request is done and before the page is
saved this model will null the variable that keeps the user so it is not put
in session. only the two key pieces of information necessary to retrieve
this user (and which are hopefully much smaller then the actual user object)
are kept in session.


d) Now I am iterating using ListView.  How exactly do I initialize the

ListView so that it uses the installed detachable model?



what do you mean? you just pass it into the constructor.

e) While rendering each row of the ListView, how do I initialize Labels so

that they in turn get the right chunk of the detachable model?



just what you did above  - new PropertyModel(item.,getModel(), name);
or if you use PropertyListView just add(new Label(name)) :)

f) And suppose I have a Label that has to be derived by say some string

concatenation or formula and OGNL notation will not work.  Will new
Label(foo, fooModel.getFoo() + bar)kind of hardcoding conflict in some
subtle way with the concept of detachable models?



write a simple model

private static class foomodel extends abstractreadonlymodel {
 private final imodel wrapped;
 public foomodel(imodel wrapped) { this.wrapped=wrapped; }
 public object getobject() { return wrapped.getobject()+bar; }
 public void detach() { wrapped.detach(); // important }
}

you do this a lot, so it is very helpful to create a superclass of the above
that helps with setting and detaching. i leave that as an excercise to you.

Thanks Igor.  This really helped, and along the way I realized I missed a
few fundamentals.  One more question below:

d) Now I am iterating using ListView.  How exactly do I initialize the

 ListView so that it uses the installed detachable model?


what do you mean? you just pass it into the constructor.



Ok I get it.  Also, when you do getModel() Wicket will search upwards the
component hierarchy right? So it does not matter even if you are on a child
panel within the page or something, yes?

e) While rendering each row of the ListView, how do I initialize Labels so

 that they in turn get the right chunk of the detachable model?


just what you did above  - new PropertyModel(item.,getModel(), name);
or if you use PropertyListView just add(new Label(name)) :)



Yep.  Honestly was not aware of PropertyListView and will look into that as
well.

f) And suppose I have a Label that has to be derived by say some string

 concatenation or formula and OGNL notation will not work.  Will new
 Label(foo, fooModel.getFoo() + bar)kind of hardcoding conflict in

no, not exactly. if you havent set a model on the component (or set it to
null) and call getmodel() wicket will search upwards for a model that
implements the compound model interface. look up compound property models on
that wiki page.
