Re: Wicket 1.5 migration: AbstractCrypt#decryptByteArray(..) throws IllegalBlockSizeException

2012-11-11 Thread Johan Compagner
what is the salt that you use?
because we use the session specific key, but that can also already be used
like that in 1.4 is it maybe a different default so that you now use a
session key as salt?

does the database have enough room voor the encrypted? is it not truncated?
Op 11 nov. 2012 17:04 schreef Alec Swan alecs...@gmail.com het volgende:

 When a user submits a form we take all parameters, encode them and
 store encoded string in the database. When the users want to see which
 values they submitted we pull the encoded string from the database,
 decode it and show values to the user.

 Encoding is done with cryptFactory.newCrypt().encryptUrlSafe(str)
 Decoding is done with cryptFactory.newCrypt().decryptUrlSafe(encodedStr)
 Where cryptFactory = new CachingSunJceCryptFactory(x);

 So, the encoded string was stored in the database with Wicket 1.4.19
 and used to work when decoded with 1.4.19. However, now we are on
 1.5.9 and we get the following exception during decoding of string
 from the database:

No this is bad, i agree with Igor, the latest page should be refreshed, not

By the way, the hybrid in 1.4 what we are using does look at the mount if
the page doesn't exists any more. And we depend on that, am i reading it

 also allowed some usecases that were not possible
 when the two were
 separate.

 you dont have to go very far to come up with an
 example where page id is
 useful.

 1. suppose you have a page with panel A that has a
 link
 2. user hits a link on the page that swaps panel A
 for panel B
 3. user presses the back button
 4. user clicks the link on panel A

 now if you turn off page id and therefore page
 versioning it goes like
 this
 1. wicket creates page and assigns it id 1
 2. page id 1 now has panel B instead of panel A
 3. page with id 1 is rerendered
 4. wicket loads page with id 1. user gets an error
 because it cannot
 find the link component the user clicked since the
 page has panel B
 instead of panel A


 This is imho not what happens with NoVersionMount.
 What happens is:

 1. wicket creates page and assigns it id 1
 2. page id 1 now has panel B instead of panel A
 3. wicket creates new page and assigns it id 2;
 depending on how the
 page keeps state either a page with panel A and
 link, or a page with
 Panel B is created.

 Hence, there is nothing broken in this scenario.
   
we were talking about something else here. the
 NoVersionMount has the
problem of losing ajax state when the user refreshes
 the page.
   
   
I believe the OP's question was for use-cases were
 Wickets default
behaviour would be preferred over using a strategy like
 NoVersionMount.
But if I understood that incorrectly, it's now my
 question  ;-).
Imho
the natural behaviour a user expects for a page-refresh
 is a fresh
up-to-date version of the page. This is exactly what
 NoVersionMount does
as it forces a newly constructed page for a refresh.
 For OP's (Chris
Colman's) shopping card example this seems perfectly
 reasonable
behaviour.
  
   it is undesirable in applications that perform navigation
 using ajax
   panel swapping. in this case a page-refresh will
 essentially take you
   back to the homepage.
  
   Fair enough
  
I have never had to build a website were it was a
 problem when the ajax
state was lost on page refresh.
  
   but you also have not built every wicket application...
  
   Obviously... to be honest, for your use case (one page
 ajax application
   that performs navigation by swapping page components) I
 have always
   chosen other frameworks, that are (imho) better suited for
 these
   usecases.
  
When wicket shows older versions of a
page (e.g. due to back button, bookmarking older
 versions, etc.), you
have to be really careful with how a page version and a
 model interact
to not run into trouble. You also loose bookmarkability
 of such pages
(in the web-browser sense, not in the wicket-sense).
  
   you also lose it if the user bookmarks the page after
 they click

Why not simply wrap your objects in a LoadableDetachableModel? That way
you don't need to force serializable objects in your code.

 With 1.5 that method is no longer available and it's causing us to make

 Is there a way to turn of page serialization in 1.5?

 How did you store non-serializable objects in the http session (http
 store) in 1.4 ?
 The session attributes should be serializable if you need clustering
 and/or session persistence.
 I guess you just didn't use any of these features.

 Take a look at https://cwiki.apache.org/confluence/x/qIaoAQ for more
 info about the stores. May be useful.

 CompoundPropertyModels, and no, there are no domain objects in there, and no

 What on earth am I doing wrong?

 My goal is to display a long list of, say, users. Each users should list a
 few labels (name, position, location, etc) and images to show who's an
 admin/poweruser. Each user has a profile picture. Each user who is also a
 manager should have image icons of their subordinates' profile pictures
 (e.g. a nested ListView) And I want 5 or 6 AJAX labels so I can quickly
 lock/unlock users, delete them, give and revoke certain rights.

 Despite lots of profiling each row is still 4K to 6K. This adds up for even
 just 50 users. Can this be reduced, at all? I mean, it seems that 56 Bytes
 is the minimum for a Label, 32 for a PropertyModel, 80 for a ListItem, and
 some 200 for an AjaxLink. 400 for an Image (or alternatively 272 for a label
 with 2 AttributeAppenders to also render an image), and unless the whole
 list disappears from the page's object graph, all those small numbers DO add
 up.

 My final hope was the RefreshingList, but no, it also keeps the list items
 stored in the page. What I really would like is a list that does not
 maintain all its items, but throws them away, just like a LDM throws away
 the domain object, and just reloads when needed. Okay, that would not work
 because I want some state in there, but you get my point.

 I really hope it's something totally obvious I missed.

 Cheers,

 Hi,


 Following some problems with page rendering in my application after post

The label will then be gone because the body is gone.
so the output will be this
html
/html

when the body container is not visible

if the label is not visible:

html
body

/body

this solution you just can throw everything in the panel or webpage
that is the IComponentResolver for all its childs...
Just look at how the code works..
IF a component can't be found on its own parent the ComponentResolver
will ask all the parents which can be IComponentResolver to render the
child..

 Hi,

 I had a stateless login form that did actually not expire

 Sorry to raise this topic again, but AFAIK this has not been answered
 yet:

 ImageButton - always stateful ?

 http://apache-wicket.1842946.n4.nabble.com/ImageButton-always-stateful-td1875620.html

 I feel I am forced to use ImageButton because I need it as
 IFormSubmittingComponent so I can distinguish between two different
 submit methods.

 It is really as simple as two image buttons on the form - one as
 login, the other as forgot password

 Many thanks for any ideas!

Re: Wicket 1.5-M1 migration experiences

2010-08-12 Thread Johan Compagner
If NamedParameter is something like;

/show?id=10test=11

IndexedParameter is not something like:

/show/id/10/test/11

thats still named, just differently outputed, but

show/10/11

indexed then the name is presumed (its 1 ,2 ,3 ,...)

2010/8/12 Major Péter majorpe...@sch.bme.hu:
 Hi,

 I've just tried to move our application to Wicket 1.5-M1, and I've faced
 with the following problems:
 * new HeaderContributor(new IHeaderContributor() {...} isn't working
 anymore, the constructor is gone.
 After looking into JavaDoc I've find out that HeaderContributor.forCss
 and other methods are deprecated in 1.4.9, but not in 1.5-M1, so wtf?

 * PageParameters#getAsLong and other helper methods are missing, instead
 we have PageParameters#getNamedParameter()#toLong and etc.

 There are Indexed Parameters and Named Parameters, what's the difference?
 based on the JavaDoc I would thought indexed parameter is like
 '/show/id/1' and named is 'show?id=1'
 if this is true, why isn't there simply a
 getParameterIDon'tCareAboutTheTypeOfIt function, if I want to support
 both of them?

 The deprecated PageParameters constructors are lacking JavaDoc
 deprecation note, or it could be a bit enhanced at least.

 * AjaxButton now has onError function, which needs to be implemented
 * IBehavior#unbind

 * In MyApplication I've had a method like this:
 @Override
    public RequestCycle newRequestCycle(Request request, Response
 response) {
        if
 (!Configuration.getEnvironment().equals(Environment.PRODUCTION)) {
            return super.newRequestCycle(request, response);
        } else {
            return new WebRequestCycle(this, (WebRequest) request,
 (WebResponse) response) {

               �...@override
                public Page onRuntimeException(Page page,
 RuntimeException ex) {
                    if (ex instanceof PageExpiredException) {
                        return new PageExpiredError();
                    }
                    return new InternalServerError(page, ex);
                }
            };
        }
    }

 now newRequestCycle is gone, we have createRequestCycle, which is final
 and it uses RequestCycleProvider. so changing this to

 setRequestCycleProvider(new IRequestCycleProvider() {

           �...@override
            public RequestCycle get(RequestCycleContext context) {
                if
 (!Configuration.getEnvironment().equals(Environment.PRODUCTION)) {
                    return new RequestCycle(context);
                } else {
                    return new RequestCycle(context) {

                       �...@override
                        protected IRequestHandler
 handleException(Exception e) {
                            //etc
                        }
                    };
                }
            }
        });

 should have the same behavior, or??

 Also I couldn't find a substitute for this:
 http://wicket.apache.org/apidocs/1.4/org/apache/wicket/protocol/http/WebApplication.html#mount(java.lang.String,%20org.apache.wicket.util.lang.PackageName)
 and also for HybridUrlCodingStrategy. Or is hybrid even needed anymore?
 Where can I find out more about these new requestmapper stuff? (Please
 don't say in wicket-examples, I'm looking for a doc, like
 https://cwiki.apache.org/confluence/display/WICKET/URL+Coding+Strategies )

 Thanks

 Peter

then you just have to check where those classes are used and where
they could be stored in a wicket component/model
and make sure you detach that object .
Wicket tells you the field hierarchy to that object so you should be
able to track it down quite easily

the only way to do this is as i described look where the exception

and go to that same page in your developer, do as your user does.
There is no other way, you really need to be in the same state.

after viewing a page, when the page gets serialized

But you could also trigger it your self,
for example you can have something in the detach() of your base page

super.onDetach()
if (development)
{
 Objects.objectToByteArray(this)
}

then you should get the same error right away

Re: Could somebody please comment on WICKET-2889?

2010-08-09 Thread Johan Compagner
I am against that patch.
You keep pagemaps in memory in the applicaiton context!
Those are session stuff stored in the HttpSession. You shouldnt keep
reference to those stuff.
This can break all kind of things (for example clustering)

If you want something like that, then it is fine if we need to change
something so that you can overwrite some stuff so that you can do what
you want without patching wicket.
But i dont want this to be default in wicket.

 Hi all,

 It's been more than 2 month since I've created WICKET-2889 and submitted a
 patch to fix it. As nobody commented yet, I thought I should mention it
 here.

 The attached patch reduced required heap space for stateful pages by 2/3
 (depends on configuration though, 100M for my application running with a
 total heap of 768M) without any noticeable impact on performance. I'm using
 a custom PageMap that requires a few trivial changes in
 SecondLevelCachePageMap (visibility and a hook called
 onAfterLastPageSet(..)). I doubt that there's any reason not to apply it for
 1.4.10. Whether to include the new class
 (ExpiringSecondLevelCacheSessionStore) is optional, but I'd consider it a
 valuable addition to core.

 Please see https://issues.apache.org/jira/browse/WICKET-2889

maybe do the actual upload through and iframe or something that has
its own pagemap?

Or block the ui in the browser as long as the upload is in progress
(but then user can still do F5, but they should know that they should
wait for it)

You can also for example use a flash uploader to a servlet that has
nice progress indicator (like gmail)

Re: IVisitorT extends Component and IFormModelUpdateListener not extending Component

2010-07-28 Thread Johan Compagner
having IComponent for me means that there are more then 1 Component..
(there are multiply implementations possible then)
So then we have to use IComponent everwhere instead of Component
That means again that it will be a quite large interface, and do we
also then get IMarkupContainer? (and so on and so on)

Why isnt there a javax.swing.IJComponent ?

If this is really a problem then why not drop the  extends Component
from the
public final S extends Component Object visitChildren
and
public static interface IVisitorT extends Component

Then you can give anything you want to it.

Problem is that you then have less type checking there. Because that
would make IVisitor completely generic

 Hi

 Yet, why not having an IComponent interface that IFormModelUpdateListener
 (and lot of other I guess) would extend ?

 And in fact it's quite the same for FormComponent. It would be handy to have
 an IFormComponent which could be used there and there.

 For example in the ListEditor's igor did, which really is a FormComponent
 but has to extend Repeater.

 hello

 I wanted to do an Component.IVisitor for all children components
 implementing IFormModelUpdateListener.

 However, IVisitor requires something extending Component, which
 IFormModelUpdateListener can't do (it's an interface).

 As such, I had to dump all generics info and do instanceof to get it
 running.

 However, for wicket 1.5 I guess, shouldn't there be an IComponent interface
 that IFormModelUpdateListener would implement ? IVisitor would then be of T
 extends IComponent and I could do an IVisitorIFormModelUpdateListener.

 What's your pick on that ?

Re: OutOfMemoryError PermGen Space...

2010-07-23 Thread Johan Compagner
i think the problem with those memory analyzers that they give you the heap
Not the non heap, which is currently the problem..

If really constantly classes are leaked without that you constantly
redeploy web applications (because that would be a leak somewhere in
wicket or the app itself)
but the only thing you do is serializing these kind of objects:


// not serializeable and doesnt have a default constructor
public class A  {
String name;

// add this constructor so the compiler doesnt generate a default one.
public A(String name)   {
   this.name = name;
}
}

public class B extends A implements Serializable {
int aNumber;
public B() {
  super(B);
 aNumber = 10;
}
 }

If you then serialize instances of B then i think you will come into
the section of the stacktrace James gave.

But this shouldnt really leak into the none heap. (and result in an
never ending grow) that would just a bug in java itself if you ask me.
i think the work around is to give the A class a private constructor:

private A() {}

Then i think nothing is tried to be generated.

 Well, if you have increased memory for the permanent generation several
 times and keep seeing this error, for me this sounds like a memory leak.

 Tuning the java garbage collection will in all cases not help here,
 because java only throws an out of memory error if garbage collection
 does not help any more.

 I would enable the following for tomcat:
 -XX:+HeapDumpOnOutOfMemoryError
 -XX:HeapDumpPath=/var/log/java/whatever

 Then you can analyse what holds all the memory after the next crash.

 A nice tool for that is the Eclipse Memory Analyzer:
 http://www.eclipse.org/mat/

 A little how to for getting started:
 http://wiki.eclipse.org/index.php/MemoryAnalyzer

 And you should search what they have at the tomcat pages and on their
 mailing list archives:
 http://wiki.apache.org/tomcat/OutOfMemory

 This is most likely not specific to wicket itself.

Re: TextFieldInteger

2010-07-23 Thread Johan Compagner
impossible

there is so such thing as ParameterizedType for the example you give..

if you do:

TextFieldInteger field = new TextFieldInteger();

then at runtime that information isnt there anymore. Its gone. welcome
to type erasure..

I think stuff like that is only there if you do:

class MyTextField extends TextFieldInteger
{
}

but then you can already do that just fine in the constructor
yourself.. (calling setType))

 I've encontered the same problem and it took me a while to figure it out

 So maybe it's a good idea to make it automatic on the framework,

 On all TextFieldE constructors without the type parameter we should call
 setType() like this:

 setType((Class?) ((ParameterizedType)
 getClass().getGenericSuperclass()).getActualTypeArguments()[0]);

 Too complicated??

Re: OutOfMemoryError PermGen Space...

2010-07-23 Thread Johan Compagner
as far as i see now if i look that the stacktrace:

java.io.ObjectStreamClass.init(ObjectStreamClass.java:413)
   java.io.ObjectStreamClass.lookup(ObjectStreamClass.java:310

so ObjectSTreamClass.lookup call there the constructor of ObjectStreamClass
lookup does check for caches but those are soft caches so these can be cleared.
It can mean 2 things, or somehow you have constantly different classes
(proxies or cglib generated other stuff?)
or the softcaches are cleared quite often
they kind of do that quite often, SoftReferences are NOT only cleared
when the jvm needs more mem but also much sooner!
You can set this system property: -XX:SoftRefLRUPolicyMSPerMB=360
that will result in a much longer live softreference...

Because there is constantly a ObjectStreamClass generated i think you
are then hitting the MethodAccessorGenerator:

 private MagicAccessorImpl generate(final Class declaringClass,
   String name,
   Class[] parameterTypes,
   Class   returnType,
   Class[] checkedExceptions,
   int modifiers,
   boolean isConstructor,
   boolean forSerialization,
   Class serializationTargetClass)

and that is constructing byte code on the fly and calling defineClass
on it which results in a new class all the time that is a
implementation of MagicAccessorImpl
that then is a fake constructor for your first none serializable
class (that didnt have one on its own)

 Are you by chance using String.intern()? That is a candidate for filling up
 the PermGen space.

 As Andreas noted, the stack trace can be completely irrelevant to the reason

Re: OutOfMemoryError PermGen Space...

2010-07-23 Thread Johan Compagner
yes those are the things that are generated:

private static synchronized String generateName(boolean isConstructor,
boolean forSerialization)
{
if (isConstructor) {
if (forSerialization) {
int num = ++serializationConstructorSymnum;
return
sun/reflect/GeneratedSerializationConstructorAccessor + num;
} else {
int num = ++constructorSymnum;
return sun/reflect/GeneratedConstructorAccessor + num;
}
} else {
int num = ++methodSymnum;
return sun/reflect/GeneratedMethodAccessor + num;
}
}


the only thing i dont get is that for you the forSerialization flag
should be true (at least the stack trace you shown us)
So for your serialization thing you should have:
GeneratedSerializationConstructorAccessor1 or something..

But i guess you have classes that generate those special constructors
even more also for not specific to serialization.

Re: OutOfMemoryError PermGen Space...

2010-07-22 Thread Johan Compagner
what kind of classes are serialized constantly?
are those proxies or other generated onces?

Somehow it has something to do with getting the default constructor of
the first none serializable class
And i think your first class in the hierarchy that is found that
doenst implement Serializable doesnt also have a default constructor
Then when that state is found it will generate a constructor method or
something (so some kind of quick asm wrapper class with that
constructor)

So look at the classes that you serialize, find the first one that is
none serializeble and give it a default constructor.
(it could be that that default constructor needs to be private)

Re: SEVERE:Pagemap null is still locked by: Thread

2010-05-19 Thread Johan Compagner
if you have a test case please make a jira issue and attach your sample.

It is strange because in onBeginRequest of a request cycle there is no page
locked what so ever.
So i dont see how this is related.

Re: 2nd try: stateless AJAX behaviors in stateful page without its serialization

2010-04-20 Thread Johan Compagner
do you want to avoid serialization or deserialization (you talk about
Session.getPage() and thats deserialization)
But deserialization will not happen because the active page is stored in
memory,
Serialization does happen at the end of a request to store the actual
content of the page, so that later on for back buttons and so on it can be
restored.

If you want to control a bit more what should be serialized or not look at
the SecondLevelCacheStore and its pagemap.


2010/4/19 Martin Schayna martin.scha...@abra.eu

 No, I want to process these requests in context of existing original page
 instance, but without page serialization.

 Standard processing of ajax requests is implemented in
 WebRequestCycleProcessor class, in method resolve(). This method is called
 with RequestParameters instance which is only parsed request parameters like
 page, pagemap and component identification. Standard wicket implementation
 of resolve() searches for page by calling Session.getPage() method -- that's
 ok, but calling this method calls also Session.touch() method, which causes
 serialization of this page after processing request...

 What I want is: in processing some specific requests do not serialize the
 page, because these requests don't change the page and they are called
 continuously by design.

 I can extend WebRequestCycleProcessor and override resolve() method, but I
 cannot avoid searching page by calling Session.getPage().

Re: What happens after browser's 'back' button?

yes we didnt do that by default because it is quite annoying behavior
Back button should be quick and shouldnt load it from the server again at
least not by default.

You can configure it for you application the way you like. But for many
others back should really be browser cache back.

  Will cause firefox to make a trip to the server when back button is

 otherwise wicket won't know that the user hit back and will ignore AJAX

 wicket knows) is not the active page.

Re: Ajax has too much control?

2010-03-21 Thread Johan Compagner
Do you add the state ddc to the ajax target when you get a ajax country event?
- Original message -

 Sven,

 Thanks for your input. It seems that you do not understand the problem I have
 (Wicket problem??? or my page problem???). I know how Ajax works by adding
 components to Ajax request target.

 When it is non-Ajax, my page runs correctly with all three controls. When
 Country DDC Ajax-controls State DDC, the two DDC works correctly. The problem 
 is
 that once this Ajax control is triggered by selecting a value in Country DDC,
 the State DDC list is NOT updated when the Locale DDC value is changed.

 I have a feel that Wicket has a problem here. I am using Wicket 1.4.7.

  DropDownChoice#wantOnSelectionChangedNotifications() will

  On Ajax request only those components are rendered you
  explicitely 'add'

   I have been learning Wicket through the WIA book. I

   I have a page with three Wicket elements:
  
   1. Locale selector through a DropDownChoice list. WIA
  has complete code about how this works and I copied the
  solution into this page
  
   2. Country DropDownChoice, whose values change between
  English and Chinese depending on Locale DDC.
  
   3. State DropDownChoice, whose values change between
  English and Chinese depending on Locale DDC. The values in
  this DDC depends on the chosen value in Country DDC.
  
   Here are the experiments
  
   Experiment#1.
  
   Country DDC does not control values in State DDC via
  Ajax and it has
  
   protected boolean
  wantOnSelectionChangedNotifications() {
      return true;
   }
  
   Everything works like a charm, which means
  
   (1) when Country DDC value changes, State DDC changes
  accodingly.
   (2) when Locale changes, both Country DDC and State
  DDC lists change display values accordingly (which means
  both DDCs show a list of values in the same language).
  
   Experiment#2.
  
   Country DDC controls values in State DDC via Ajax. In
  this case, when page is first loaded, I do not touch the
  Country DDC or State DDC. I simply change locale value any
  number of times, both Country DDC and State DDC lists change
  correctly depending on the session locale. Here is the
  strange thing. Then I change Country DDC value, State DDC
  changes correctly. Since then, HOWEVER, if I change locale
  values, ONLY Country DDC list changes correctly; State DDC
  list is not updated. It seems Wicket decides that State DDC
  is forever Aja-controlled by Country DDC only.
  
   Not qure sure if this a bug, design, or I did
  something wrong.
  
   Please let me if you have difficulty understanding the
  experiments.
  
   Thanks for any info or help.

If our analysis is correct this is essentially the problem reported as

only in about one in every thousand requests with no apparent
consistent pattern about what the user has been doing. Can anybody

particular:
   
- is there a practical way to find out what is causing the
serialization problem. The stack trace is no help. We do in many cases
have large amounts of data in the session, but doubling the default
stack size leaves the problem frequency unchanged leading us to
suspect a logical error rather the sheer amount of data.
   
- by overriding RequestCycle.detach() and catching the
StackOverflowError we can get control when the error occurs. Is there
any way we can persuade Wicket to release the pagemap lock? I have
looked at the code and this doesn't look straightforward.
   
- can we get Wicket itself to suppress the StackOverflowError so that

 seeing an increased frequency of pagemap locking which is beginning to
 be a serious problem for the users. By subclassing WebRequestCycle we
 have identified that a StackOverflowError under serialization in
 RequestCycle.detach() leaves the pagemap locked for the next minute.
 If our analysis is correct this is essentially the problem reported as
 https://issues.apache.org/jira/browse/WICKET-2075. Unfortunately we
 cannot reproduce the problem in our test environment and it occurs
 only in about one in every thousand requests with no apparent
 consistent pattern about what the user has been doing. Can anybody
 suggest an immediate strategy for further investigations? In
 particular:

 - is there a practical way to find out what is causing the
 serialization problem. The stack trace is no help. We do in many cases
 have large amounts of data in the session, but doubling the default
 stack size leaves the problem frequency unchanged leading us to
 suspect a logical error rather the sheer amount of data.

 - by overriding RequestCycle.detach() and catching the
 StackOverflowError we can get control when the error occurs. Is there
 any way we can persuade Wicket to release the pagemap lock? I have
 looked at the code and this doesn't look straightforward.

 - can we get Wicket itself to suppress the StackOverflowError so that
 detach() continues and releases the lock?

 Grateful for any suggestions.

 Nigel

Re: Strange classloader issues

2010-02-02 Thread Johan Compagner
look at your html code
because somehow you get those kind of urls
org.apache.wicket.ajax.WicketAjax%3C/div%3E%3Cdiv%20class=
back to wicket and that seems very weird.
it seems that that is a piece of html with those div and class stuff.

It could also be that this is done by some header contribution ?

Re: setRequired( false ) does not work on Integer textfield?

an int (primitive) is always required.
We have to set it to something. cant be null
if you want to be able to not require it (so null) make it an Integer not
int

 getting the message Field 'AdaptingHitCountThreshold' is required.
 Why? In my pojo data object (lMcsConfig), the field is really of type

if you constantly target exactly that url

Re: Wicket feedback

2009-12-24 Thread Johan Compagner
So you just want to throw all the components of a page or panel (the one
with markup) in 1 big place.
then all those have to be uniquely named ofcourse. Throughout the complete
page.

Repeaters will then be a bit special i guess. Because they are generation
ListItem components for you
that then also should be added to the page i guess (and made unique per
repeater) And they point again to some of the global pool components?

I think this will cost performance (if we still use linear lists) or memory
(if we are going to use hashmaps).

But after that if we all have this.. Wont the code be unreadable?
What is in where? Because i guess you then want to just add alll the
components you have on a page in the page constructor..
So that one will be quite large with no relations to each other.. Or are you
going to group them again? But then you are doing exactly the thing you do
now

johan

P.S. i am against having 1 text field component.. TextArea and TexField are
also in html completely different beasts. I know there are ui (swt) that do
use 1, but others (swing) dont i like that separation..

 hmm..

  It should be sufficient that the artist thinks the gfx are immacculate
  and that the java developer thinks the code is immacculate. Why do we
  need to couple java with html hierarchies and stuff? Some namespace
  attribute could suffice to allow nested components.
 
  put your money where your mouth is, come up with a prototype.

 Does wicket have a single point where it manages which component
 becomes the child of another and where the markup is loaded from? If
 yes, I could try to introduce a namespace attribute.

  we synchronize with the markup and lose some OOP, but we gain in desing.
  Have you ever change the look and feel of your application? with wicket
 it
  is really easy, in other frameworks it is a nightmare.

 If you give up coupling between html and java you do not lose the ease
 of design. Actually you will gain more ease and freedom of design.

 Furthermore, coding will be much faster as in most (80-90%) cases you
 need only a single namespace per panel and you could go about it
 without the need to worry about how the components are nested in html
  java.

 When I build a new panel I believe a significant amount of time is
 spent in synchronizing html and java. That's work time spent that is
 not really adding value in linear amount.

   Hi all,
   We've just finished with success a wicket project for a large
 online
   retailer. I think wicket is the best framework out there, but as
 any
   other
   project there is room for improvement. I will talk about some
 topics
   bellow,
   I hope it can help in some way.
  
   - Separation of corcerns
   I think we could get a better separation of concerns if page
 class
  were
   focused more in behavior and html were more focused in display
 (or
  view).
   What I mean is, some times we have components that the main
 purpose is
  to
   add behavior, and we have to add extra markup just to satisfy
 wicket
  1:1
   mapping. Take CheckGroup for exaple, it is a component focused on
   behavior,
   even though we have to add a reference to it in HTML.
  
  
   a redesigned CheckGroup is welcome, but that component is the
   exception and not the rule.
  
  
  
   Yes, but how do we deal with the requirement of all components
 having a
  HTML
   representation? The same happens with RadioGroup, even with
 wicket-1055
   solved, the HTML reference is still there.
  
   When creating composite input fields (like date), the usual way
 is to
   create
   a panel even if you are not interested in reusability. A
 interesting
   aproach
   is to insert a hidden text field in HTML mapped to a component
 that
   controls
   other components input. It makes easier to integrate with
 designer and
  to
   preview in browser. If we didn't have this limitation the hidden
 input
   would
   not be necessary and the development of behavior focused
 components
  would
   be
   easier.
  
  
   i dont really understand this..the usual way would be to extend a
   FormComponentPanel, not a Panel. are you saying that because the
 Panel
   derivatives are just adiv  in the markup it makes it difficult
 for
   the designers?

 Let's stress the counter-example, but first the questions:
 - Basic questions: Why does the counter not increment on reload?
 - Why is the WebPage created every time I reload the website, I though they
 are only created once?
 - Why isn't the Model used, so the Model keeps track where the value comes
 from? (ok, if the page is recreated every time, the model will be recreated,
 too. maybe solved with previous question).

 The Code:

 public class HomePage extends WebPage {

private Long value = 0L;

public HomePage(final PageParameters parameters) {
Model m = new ModelSerializable() {

private static final long serialVersionUID = 1L;
// It doesn't matters if I take this, or value

Hi,
   
In my application I have a number of fields that allow validation,
  by
   means
of a validation CheckBox. In order to provide some flexibility for
  this
   kind
of validation fields, I'd like to have them implemented in a
  Component
   (i.e.
ValidationTickPanel), so that they provide their own markup and
  other
   panels
using it should not know about its contents. ValidationTickPanel
  extends
Panel in order to be able to provide own markup.
   
The problem is, I'd like to have the CheckBox's wicket:id set from
  the
parent panel (in order to use CompoundPropertyModel). But I'm
 afraid
  that
it's impossible to have a variable wicket_id inside
ValidationTickPanel.html...
   
public class ValidationTick extends Panel implements
  RestrictedComponent
   {
   public ValidationTick(String componentId, String checkId, IModel
checkModel){
   super(componentId);
   CheckBox check =  new CheckBox(checkId, checkModel);
   Label label = new Label(checkId+Label, new
StringResourceModel());
   add(check);
   add(label);
   }
}
   
wicket:panel
   input type=checkbox wicket:id=???/input
   
/wicket:panel
   
Usually, checkModel would be null as the goal would be to use
compoundPropertyModel on the checkBox..My question is, is it
  possible
  to
achieve this ? Or should I be discarding the CPM idea and passing
  for
instance a PropertyModel to ValidationTickPanel ?
   
Thanks a lot,
Xavier

 I have a page with about 10 text fields. The model for the page is a

 RestartResponseAtInterceptPageException. All of the keys in the ValueMap

 What do I need to do to fix this?

  Hi all,
 
  We're in the process of going live with our wicket app, so we're trying
 to
  figure out certain details, currently PageStore size.
 
  I notice that by looking at the page store on disk, typically our pages
 add
  10-20kb each to the pagemap. The default 10mb limit would store a lot
  of
  pages, but we were thinking of using a smaller limit. I tried adjusting
 the
  limit to 100kb, and as expected, the page store size capped out at
  about
  100kb.
 
  I was expecting the consequence of this to be that the back button
  would
 not
  work all the way to the beginning. Actually, what happens is that,
  after
 my
  page map size hits the limit and stops growing, even if I continue to
 click
  around the app for a while, I can still hit the back button all the way
 back
  to the login, without hitting our page expired page. This surprised
  me.
 Is
  this expected behavior? If the back button works with a 100kb page map
 file,
  why use a 10mb one?
 
  Any help would be appreciated!

it could be that if you do that then in normal use

So i guess you should also try to let the server know.

 with

 but the post are so old that I understand those are fixed bug ?

 No need to precise what versions of wicket stuffs I use, your can
 see

 5.5.25.

Re: Asynchronous construction of page

2009-11-28 Thread Johan Compagner
load that data in separate threads, dont touch any wicket components
in those threads
make a component like ajaxlazyload that polls for that data if still
not there use a timer of a few seconds to test it again

On 28/11/2009, Kaspar Fischer kaspar.fisc...@dreizak.com wrote:
 Because the requests will be sequential (a problem in general but not so
 much in my case) and because I have an auto-completion field on the same
 page. As I understand it, having some AjaxLazyLoadPanel's active on my page,
 the auto-completion requests will be queued. So if the loading of the lazy
 panels takes time, the user experiences slow response in the auto-completion
 field. Please correct me if I am wrong.

Re: TabbedPanel no IModel?

2009-11-27 Thread Johan Compagner
yes that component isnt nicely written, the tabs field should be a model
(make a jira entry for this)

but from the outside you can use:

public final ListITab getTabs()
{
return tabs;
}


to add or remove tabs.

That is the same list as you give the constructor
So you could use that as your model object
Just have your own kind of List impl and fill that up dynamically

 How is it possible to reload the list without model?

Re: PropertyModels *without* strings

2009-11-26 Thread Johan Compagner
the pro's of this compared to the SafeProperty is that the safe property
needs to generate proxies at runtime so you need CGLIB and you could have
issues with final classes
this is more a develop environment solution which is because of that a bit
nicer.

Re: Serializing page state into URL instead of session?

2009-09-17 Thread Johan Compagner
we tried that already but dismissed it
wicket has no support for this and for these kind of things to work
everything must be come a post
you cant use any normal links.

also you are trading in memory for cpu speed and bandwidth which is in my
eyes more expensive then memory or hd space

Page expired shouldnt really happen anymore in wicket 1.3 and greater anyway
so that is not a problem you should try to fix

Do you have memory problems or are you trying to fix something that isnt
even a problem?

 Hi,

 Is it possible to get rid of sessions by automatically saving page state
 directly to URL, not into session?
 So, for example, this can look like: ?pagestate=automatically serialized
 state of the page
 Of course, this won't work when page has models with large state because of
 URL length limit, but will work perfectly in lots of cases.
 This solution would not sacrifice Wicket's stateful nature and solve Page
 expired problem.

 If this requires some deep changes of Wicket itself, what parts of Wicket
 are to look into?

 Thanks!

Besides that if that would be a problem just get an SSD and place that into

  and he suggested to use HttpSessionStore instead of the second cache...
 
  I looked into the javadoc and the code itself and understood the
  differences.
 
  However, can anyone explain in a bit more detail the implications /
  differences of using the Http instead of the SecondLayer?
  The reason I'm asking this, is because, if it's better use, then I want
 to
  convince my team that we change the implementation of our application to
 use
  Http store.
 
 
  Thanks very much.

Re: RequestCycle().urlFor not work

2009-09-12 Thread Johan Compagner
Which version of wicket do you use?

Why do you need absoluut urls?

On 11/09/2009, Dima Rzhevskiy d...@rzhevskiy.info wrote:
 Sorry, yes, urlFor return correct result.
 toAbsolutePath(final String relativePagePath) do not return result what I
 expected.
  javadoc copy/pasted from toAbsolutePath(final String requestPath, String
 relativePagePath)...

 I undestand that it is nessesary to use toAbsolutePath(final String
 requestPath, String relativePagePath) where requestPath nessesaty take in
 constructor:

 public class X1 extends WebPage {

 private static final Logger LOG = LoggerFactory.getLogger(X1.class);

 public X1(final PageParameters parameters) {

  CharSequence url = getRequestCycle().urlFor(getClass().class, new
 PageParameters());
  final String outerUrl2=
 RequestUtils.toAbsolutePath(url.toString());   //get
  add(new AjaxLink(message){
 @Override
 public void onClick(AjaxRequestTarget ajaxRequestTarget) {
 CharSequence url =
 getRequestCycle().urlFor(X1.class, new PageParameters());
 String url2=
 RequestUtils.toAbsolutePath(outerUrl2, url.toString());
 LOG.info(url=+url);
 LOG.info(url2=+url2);
 }
 });

 }
 }


 But this code look ugly..
 Is better way of obtaining absolute url exists ?

 Hi,

 With forms on Wicket pages, it appears that on submit which is HTTP

 How is it possible to send the rendered form page back to the broser

 This could allow text to be changed thrue a web form. If the text was

 Who's in general responsible to detach an IModel, specially those who

we already have session unique pageid's:

Then you dont have to have pagemap or enable the multi window support
You only need that if you really want to now that users uses different tabs.

no it doesnt.

if you make sure that the pageid is unique across the session
then you dont need pagemaps. And you can hold everything in 1 pagemap.

And if you do that then make sure then all he pages go into 1 pagemap
then make sure that:

*
