i did understand you, if you can't do anything to the object that is
generated
is fine by me. But i still say, don't have it as a serializeable field in
your pages
that you can handle. Just lookup the EJB when you need it and cache it in a
transient variable

Johan, I don't think you understand what the unserializable object is. My
remote EJB is serializable by definition. However, the object I am having
issues is an internally generated rmi stub created by WebLogic. This
object
was not created by me, I have no control over it and should not even be
aware of what the exact implementation of this stub is since this is all
handled behind the scenes by WebLogic is but it became an issue because in
debug mode wicket tries to serialize it.

Re: [Wicket-user] form action url

2007-06-07 Thread Frank Bille

Unless you have a specific reason to use that Filter for authorization I
surgest that you take a look at SimplePageAuthorizationStrategy, which
allows you to define which pages should be protected:

http://www.wicketframework.org/apidocs/wicket/authorization/strategies/page/SimplePageAuthorizationStrategy.html

Then you don't have to worry about if the url is correct according to you
filter.

the action of this form is rendering as
action="/paws?wicket:interface=:11:accountForm::IFormSubmitListener".
This makes the the URI /paws Is there a way to have this form action POST

action="/paws/AccountPage?wicket:interface=:11:accountForm::IFormSubmitListener".
Does the page know about its own mapping?

Otherwise I will have to a hack and check the QueryString on anything going to

Re: [Wicket-user] wicket did not make the grade.

2007-06-07 Thread howzat

I too would be sad to announce this outcome, especially after investing the
time necessary to research and evaluate the options and having looked into
some of the ways wicket improves the whole development experience for web
apps and, the quality of the end product.
I have only been working with wicket for a short time but can already
confirm, coming from a very OO background, that it is a pleasure to develop
with. The philosophy and design of the framework just make sense; they have
clearly been well thought out - the design and user experience (ie the
developers' experience) is second to no other "competing" framework that I
have  come across.
I agree that it takes a bit of learning, especially if an OO solution for
the web-tier is not critical and the team is already familiar with Model-2,
but, in my experience, there is no point dwelling on your team's decision if
it has already been made. At the end of the day, most of these frameworks do
work and are proven too, it's just that some are more interesting, powerful
and enjoyable to work with, especially on larger applications.
If during a future evaluation you were to come to this forum looking for
pointers and answers about "how to do stuff in wicket" (and I do think that
the documentation/examples can be improved in due course, hopefully once the
incubation dust has settled) before your decision is reached, I am sure that
forum members here with a much greater feel for wicket than myself, would be
pleased to offer guidance/suggestions/feedback (and quickly, as you can see
from the high-quality, unbiased responses you have already received on this
thread) on some of the points your team concluded were wicket's relative
merits or otherwise.
Good luck with your project.

Re: [Wicket-user] Form redirect issue

2007-06-07 Thread hillj2

This may be an issue with our proxy server not being able to handle redirects
properly.  We found on the post redirect it was sending the port/path of our
app server back to the browser for the redirect.  When we implemented the
ONE_PASS_RENDER strategy it fixed the default form processing.

For now we're still using the Referer header to redirect back to our
non-wicket pages, because I don't know how to get the correct URL to
redirect to and haven't had enough time playing around with 1.3 to find an
alternative solution, since we've been rushed just to get the form working
for now.  Hopefully I'll have time to play around with 1.3 some more to find
a better solution, but at least the form is functioning for now.

Re: [Wicket-user] FormTester, DropDownChoice & Validation

2007-06-07 Thread Ingram Chen


I dig into 1.3 trunk, and yes, in FormTester constructor:

*else* *if* ( (formComponent *instanceof* DropDownChoice) ||
(formComponent *instanceof* RadioChoice) ||
   (formComponent *instanceof* CheckBox))
{
 setFormComponentValue(formComponent, formComponent.getValue());
}

current implementation does not consider null model object.  I think
possible fix is:

*else* *if* ( (formComponent *instanceof* DropDownChoice) ||
(formComponent *instanceof* RadioChoice) ||
   (formComponent *instanceof* CheckBox))
{
 if(formComponent.getModelObject() == null)
 {
setFormComponentValue(formComponent, formComponent.getValue());
 }
}

and It seems FormTester lack support for RadioGroup while construction,
(only CheckGroup supported).


On 6/7/07, severian <[EMAIL PROTECTED]> wrote:



I'm having a problem with DropDownChoice components & FormTester.  I've
declared my DropDownChoice as required, which works fine via the browser -
the correct validation feedback is given when I fail to make a selection.

However, when trying to write a test demonstrating this, no validation
feedback is given.  It seems that when using the browser,
FormComponent.checkRequired() is given the input as "" (empty string), and
so correctly declares this as invalid.  But when using FormTester,
FormComponent.checkRequired() is given the input as "-1", and so correctly
declares this as valid.

This smells like a bug somewhere inside FormTester - the value "-1" should
not be set for a DropDownChoice with no selection.  If I call
FormTester.setValue(dropDownId, "") before calling FormTester.submit(), I
get the desired behaviour, but obviously that's pretty ugly.  Anyone got
any
ideas or should I raise a JIRA?

Re: [Wicket-user] Wicket 1.2.6 Development mode serialization checks and remote EJB's



It would be a simple thing to look up the bean in each method in the service
locater as versus keeping a reference. However, this is not how the existing
service locaters here have been coded and they've been clear about wanting
the new stuff to mimic the old stuff. 
The best way to solve the issue would be to get rid of EJB altogather since
the usage requirements of the project are pretty light but I'm not here to
change the world (none of these arguments would be easy), just to get their
project coded for them as per their requirements. They are going to be
maintaining it so I suppose it's fair to code it exactly like the existing
code.

Not really. I mean a @SpringBean *construct*, like you can find in the
Spring integration project. That project generates proxies for every
@SpringBean annot found. These proxies are light and serializable, and
internally hold a transient reference to the actual spring bean. When
serialized, the spring bean instance is discarded; the proxy will
locate it again when it is called.

You said you can't use annotations, so that trick wouldn't go here for
you. There used to be a project[1] (now only for 1.2.x) that used
commons attributes[2] for the same purpose, but we're not maintaining
it for 1.3 anymore (though it is stored as a wicket-stuff project

Alternatively, you can just locate the bean just in time. Are you sure
you need to keep a reference to it in your component(s)? And consider
that *if* you need a reference, it's probably per-request (so you'll
want a new one when a new request starts). If that is true, you can

Re: [Wicket-user] Injecting session scoped beans with wicket-spring-annot

2007-06-07 Thread Igor Vaynberg

this might be due to the fact that wicket performs a test-lookup on the bean
to make sure its there and if not fail early. that might be what is causing
the problem. will need to have a look.

see AnnotProxyFieldValueFactory.testLocator(). that was ok for singleton
beans, but probably not ok for prototype beans if you really care about how
many are created. so we might have to remove that failfast functionality.

Re: [Wicket-user] Prototype scoped Spring beans

2007-06-07 Thread Igor Vaynberg

hrm. you say you will have a serialization problem if you lookup the bean
directly and hold on to it. but isnt that exactly what you want? to pull out
a prototype bean and keep it inside the form's scope? the form is in
httpsession and so the bean will be serialized. so if that is what you want
to do you have to make sure the bean is serializable and do the lookup
yourself.

we can probably add @SpringBean(transient=false) or something like that to
keep the reference instead of discarding it, but that wont solve your
serialization problem, it will just save you doing the lookup yourself.

so what exactly do you want?

I put a breakpoint in the constructor of my Form, which has the
@SpringBean annotation on ia property named logic.

Before the super() call, logic is null.

After that, it is set to $Proxy39, with a h-attribute to a
org.apache.wicket.proxy.LazyInitProxyFactory$JdkHandler. The target
property of the handler is null.

After the next line, where I call a method from logic, the target
property is set to the bean instance.

So it seems that the reference gets lost in the first call.

But, as you said that the bean is transient anyway, I think that
prototype beans could not be used that way for holding state of wicket
components, because that state should certainly also be kept when
using the back button.

I'm not sure what is best then. I could get a reference to the spring
bean directly from ApplicationContext, and just keep it. But then I
would face the problem of serialization.

The best thing would be IMHO if the proxy could somehow do an
automatic re-lookup from Spring for prototype beans, so that not a new
instance is fetched from the container, but the same as before. But I
don't know enough about Spring to say if that is even possible.

Not really. I mean a @SpringBean *construct*, like you can find in the
Spring integration project. That project generates proxies for every
@SpringBean annot found. These proxies are light and serializable, and
internally hold a transient reference to the actual spring bean. When
serialized, the spring bean instance is discarded; the proxy will
locate it again when it is called.

You said you can't use annotations, so that trick wouldn't go here for
you. There used to be a project[1] (now only for 1.2.x) that used
commons attributes[2] for the same purpose, but we're not maintaining
it for 1.3 anymore (though it is stored as a wicket-stuff project
now[3]).

Alternatively, you can just locate the bean just in time. Are you sure
you need to keep a reference to it in your component(s)? And consider
that *if* you need a reference, it's probably per-request (so you'll
want a new one when a new request starts). If that is true, you can
just set the reference lazily (get it when you actually access it),
and null it in the components onDetach method (override that method;
it will be called when a request is handled) so that it won't be
serialized.

[Wicket-user] TreeTable : html tags in cells howto

2007-06-07 Thread Matthieu Casanova


Hi, I wanted to add some custom tags in the cells of my TreeTable, but if I
return html code in the public String renderNode(TreeNode node) method of my
column,
the tags are stripped.
I found this idea to do what I want, it works but it's not very well :
I had to replace the TreeFragment used in TreeTable by my own TreeFragment,
and set the flag "FLAG_ESCAPE_MODEL_STRINGS" to false on the Label in the
Fragment
To replace the TreeFragment I had to extend the TreeTable. Here is what I
did (I'm using Wicket 1.2.6)

private static class MyTree extends TreeTable
   {
   public MyTree(String id, TreeModel model, IColumn columns[])
   {
   super(id, model, columns);
   }

   protected Component newTreePanel(MarkupContainer parent, String id,
TreeNode node, int level, IRenderNodeCallback renderNodeCallback)
   {
   return new TreeFragment(id, node, level,
renderNodeCallback);
   }

   public class TreeFragment extends Fragment
   {
   private static final long serialVersionUID = 1L;

   public TreeFragment(String id, final TreeNode node, int level,
   final
TreeTable.IRenderNodeCallbackrenderNodeCallback)
   {
   super(id, "fragment");

   add(newIndentation(this, "indent", node, level));

   add(newJunctionLink(this, "link", "image", node));

   MarkupContainer nodeLink = newNodeLink(this, "nodeLink",
node);
   add(nodeLink);

   nodeLink.add(newNodeIcon(nodeLink, "icon", node));

   Label child = new Label("label", new AbstractReadOnlyModel()
   {
   private static final long serialVersionUID = 1L;

   /**
* @see wicket.model.AbstractReadOnlyModel#getObject(
wicket.Component)
*/
   public Object getObject(Component c)
   {
   return renderNodeCallback.renderNode(node);
   }
   });
   child.setEscapeModelStrings(false);
   nodeLink.add(child);
   }
   }
   }


I think there is something strange in this API : the ida of using the
TreeModel was great, but why not using something close to the
TreeCellRenderer so it would be possible to have true components in the
cells

Re: [Wicket-user] Wicket 1.2.6 Development mode serialization checks and remote EJB's

Eelco, I realized that you are recommending using Spring or looking up the
bean on the fly some other way but I am working for a place where Spring is
not part of the "approved" stack and they have an established way that
access to EJB's is coded. I am a contracter here and I have to do things
exactly how it has been established by the architecture team. I will forward
your comments to them so that they can see the advantage of your approach,I
am sure they will be interested in the suggestion.

Re: [Wicket-user] Form redirect issue

2007-06-07 Thread hillj2


We're still having issues with our reverse proxy.  This doesn't even involve
the redirect issue yet.  When our form hits user-defined validation errors
we pass messages back to the feedback panel an then do nothing (so the
default behavior kicks in to send it back to the form page).  But the url it
comes up with to return to the page is bogus.  The wicket logs output:

DEBUG 2007-06-07 10:54:38,378 http.WebResponse (redirect:196) - Redirecting
to ?wicket:interface=:0

which is just the query string.  Am I missing some major configuration
parameter?  Or is the default behavior just not doing the right thing?

Thanks.

Joel

Re: [Wicket-user] Wicket 1.2.6 Development mode serialization checks and remote EJB's

Thanks so much Eelco! Your reply is exactly what i was looking for! We are
using JDK 1.4 so I cannot use annotations but the other thing would work. 
Johan, I don't think you understand what the unserializable object is. My
remote EJB is serializable by definition. However, the object I am having
issues is an internally generated rmi stub created by WebLogic. This object
was not created by me, I have no control over it and should not even be
aware of what the exact implementation of this stub is since this is all
handled behind the scenes by WebLogic is but it became an issue because in
debug mode wicket tries to serialize it.

You can get it straight from subversion at
http://svn.apache.org/repos/asf/incubator/wicket/trunk/jdk-1.5/wicket-examples.
Make it an Eclipse project by executing 'mvn eclipse:eclipse' and
you're ready to import it in your workspace.

Sure. We feel we've done quite our bit with the examples though; most
constructs and components are convered, and if we introduce new ones,
we typically add them to the examples project. Also, it's a project we
do in our free time mostly, and our core goal is to deliver a
framework that works well for the current users. It's nice to get new
users on board, but it's a secondairy goal.

Anyway, if you miss something specific, please send a note/ open a
feature request, and hopefully we (the community) can help out.

Re: [Wicket-user] Wicket Security Configuration Question

2007-06-07 Thread craigdd

This original post was under wicket stuff users list and I've reposted it
hear for more visibility, as requested by Martijn.  The following is the
response that I got from Maurice.

Hi,

what i mean is this: By default SecurePageLink (and all other links
with the same securitycheck) checks for an enable action on the page
the link points to. This check occurs both in the render (where is
decided if the link should be clickable) and in the onclick (just to
check if nobody spoofed an url to trigger a link click where it is not
allowed).

Maybe an example will make things more clear (note to self to update
the getting started)
HomePage contains a SecurePageLink to PageA.
We should declare at least .HomePage, "render"; in our policy or
we will never see the homepage. With just this the link will not be
rendered because it lacks .PageA, "render";
So if we put that in the policy to we will see a disabled link.
(wicket turns it into a span by default) but because the component is
still available on the server side someone could spoof the url and
trigger wicket into thinking the link was clicked, fortunatly the
second check i mentioned earlier will detect this and send you to the
accessdenied page.
Only if we make sure our policy also contains .PageA, "enable";
the link will be fully operational.

I hope this answered your question. :)

But if you want to get realy confused you should read on because there
is an alternative mode in which it is possible to show the link even
if we have not granted render to PageA.
I am actually working on some examples showing this alternate mode,
but they are not yet available.
To activate the alternate rendering mode you need to do this:
((LinkSecurityCheck)link.getSecurityCheck()).setUseAlternativeRenderCheck(true);
Given the above example and a policy file only containing
HomePage, "inherit, render";
the link will render as a disabled link. Note the inherit, this means
all child components on the homepage are allowed to render. Optionally
we could replace that one line with the following two lines
HomePage, "render"; and HomePage:link, "render"; Assuming the
wicket id of our link is link :) To enable the link we would still
require PageA, "enable"; in our policy.

Thanks for checking out swarm and wasp, i hope i did not just confuse
the hell out you :)

[Wicket-user] Wicket Security Configuration Question

2007-06-07 Thread craigdd


In look looking the getting started page for wicket security I came across
the following block on text when describing the configuration of principals.

What we just did is grant everyone the right to see (render) our HomePage,
if there are secure components on the homepage we can see them too
(inherit). In addition we granted links to our homepage the right to be
clicked (enable). Because we do not want to give links on our homepage the
right to be clicked we did not place the enable action on the previous line
with the inherit. If we know for a fact that there are absolutely no links
pointing to the homepage we could delete the second line, but generally you
will want these two lines for any given secure page. If you think, what a
long line isn't there a shorter way, then i have good news for you. Hive
supports aliases. This means that besides the build in aliases for
permissions you can add your own aliases for permissions, principals and
names, just not for actions!. aliases can be concatenated but not nested.
sow if we rewrite our policy to use aliases we get

Just to clarify, when you say "In addition we granted links to our homepage
the right to be clicked (enable)", does this mean that the link, which I
assume you mean , is able to be physically clicked? And if it was the
opposite, as is the next line of the configuration "HomePage", "enable"",
does this mean that the link is disabled to the user, or that it is enabled
but you will get an access error exception on the server side?

Thanks
Craig

[Wicket-user] FormTester, DropDownChoice & Validation

2007-06-07 Thread severian


I'm having a problem with DropDownChoice components & FormTester.  I've
declared my DropDownChoice as required, which works fine via the browser -
the correct validation feedback is given when I fail to make a selection.

However, when trying to write a test demonstrating this, no validation
feedback is given.  It seems that when using the browser,
FormComponent.checkRequired() is given the input as "" (empty string), and
so correctly declares this as invalid.  But when using FormTester,
FormComponent.checkRequired() is given the input as "-1", and so correctly
declares this as valid.

This smells like a bug somewhere inside FormTester - the value "-1" should
not be set for a DropDownChoice with no selection.  If I call
FormTester.setValue(dropDownId, "") before calling FormTester.submit(), I
get the desired behaviour, but obviously that's pretty ugly.  Anyone got any
ideas or should I raise a JIRA?

But there is. You can turn the check off, even for development mode.
See IDebugSettings#setSerializeSessionAttributes[1]

What you probably want in the end though, is a construct like
@SpringBean or just look the bean up right at the moment you need it
without holding the reference.

Re: [Wicket-user] Wicket 1.2.6 Development mode serialization checks and remote EJB's


so the end result is that in production you have now a none serializeable
object in the session?
that is not really the right solution if you ask me.

also going to wicket1.3 (with SecondLevelCache) is not an option then

Re: [Wicket-user] Wicket 1.2.6 Development mode serialization checks and remote EJB's



It's not a case of an unknown reference causing the not serializable
exception. I know which object is not serializable and it is the concrete
proxy object created by WebLogic for my remote EJB. I ended up checking if I
was in development mode and then using a transient variable and then using a
another variable which is not transient when the app is running in a
production environment. I was hesitant to simply mark the EJB as transient
in case it caused issues in the production environment. Thanks all for your

[Wicket-user] turning off markup validation

2007-06-07 Thread Vít Rozkovec

Good day,
one more issue - is there some way how to turn of markup validation?
In my template I am using this:


   
   
   
   
   
   [text odkazu]
   
   
   
   
   
   
   
   


















The problem is that wicket complains about using fragments this way with 
message:

WicketMessage: Tag '' (line 20, column 30) has a mismatched close 
tag at '' (line 21, column 1)


My purpose is to first initialize a menu tree and then traversing whole 
tree, generating drop-down menu with the structure which can be seen here:
http://www.cssplay.co.uk/menus/css/final_drop.txt
The whole working menu can bee seen here:
http://www.cssplay.co.uk/menus/final_drop.html

What solution can be for my problem?
Or does wicket has natively some support for creating dropdown menus? I 
was unable to find.
Thanks for any help.

[Wicket-user] Use case - dublin core METADATA generator

2007-06-07 Thread Vít Rozkovec

Hallo,
I have this problem and I need to get a bit of kick-start.
See this page:
http://www.webarchiv.cz/generator/dc.php
(in Czech language, but I hope you get the picture)

This is the generator which I need to replicate with all of its 
functionality in Wicket.
So far I have managed to be able to add and remove fields for one group, 
I did this with panel. I created add and remove links which have as the 
response page the panel with a number of row (I am trying to get it 
functional just for a panel at first).
Just a solution which came to my mind - should I create some wrapper 
class which contains all the elements settings and their values and pass 
it as an argument for page which generates the form and set this page as 
a response page for a add/remove link?

Or is there some other, better way how can I manage to preserve already 
entered values when adding those fields at run-time?
How can I access all the elements of the form after the submit, 
including those dynamically created ones?

Give me please just some clue how to achieve this, I am a kind of newbie.


Thanks alot.
Regards Vitek

With a bit of luck we'll start work on a new beta release, or rc1 this
week/weekend. Keep track of the development list

2007-06-07 Thread hillj2


Well after playing around with setContextPath() a bit, we've decided to try
and get 1.3 working.  It would be nice if it had an official release, but
for now we only have one form done in wicket, so that shouldn't be too much
of a problem.  By the time we have more wicket pages a stable 1.3 release
will probably be available.  Thanks for you help, I'll let you know how it
turns out (or if we still have issues).

Hi, I'm not sure but I had such problems with a ListView because I added

[Wicket-user] [GMAP contrib] IE7 Ajax target appendJavascript not working?

2007-06-07 Thread Nino Saturnino Martinez Vazquez Wael

Hi

We are experiencing some issues with ajax in IE7, possibly IE6 as well 
when using the target.appendjavascript. Are there any workarounds?


I've looked a bit at 
http://www.nabble.com/-BUG-%3Cscript%3E-tag-evaluation-in-IE-t3839952.html 
but it does not seem to work.


Any ideas, solutions will be highly appreciated, as this are a 
showstopper for the v1 release of the gmap contrib.

regards Nino

Re: [Wicket-user] wicket did not make the grade.

2007-06-07 Thread A_flj_

Bad bad bad bad thing that the examples for the wicket-extensions are either
hard to find or not documented very well. I'm trying for half a day now to
find an example markup for inserting a treetable, but could not find
anything.

IMO it would be _very_ useful to make wars/jars/zips with Eclipse projects
available for download for all wicket-extensions examples. And also easy to
do, right?

IMO programming with something new is very much like cooking: you never get
it perfectly right before you see somebody else doing it properly. If you
(experienced wicket users/wicket developers) just give us (beginners)
readymade food for tasting, we'll never start cooking your receipes, no
matter how much we like the taste. We have to see you cooking.

[Wicket-user] Configuration Interceptor

2007-06-07 Thread Sven Schliesing

Hi,

I'm trying to build a "ConfigurationInterceptor" for my wicket-application.

Goal of this is the easy configuration file handling even when updating 
the application.

The Application is started and looks if it has a property file 
"configFileLocation.properties" (this just contains the name of the real 
configuration file) in it's webroot.
- If it is not found all future requests get redirected to a wizard-page 
where the user can configure the location of the _real_ configuration 
file. After this configuration step the file 
"configFileLocation.properties" is created.



In a genuine web-application I would use a ServletFilter for that that 
checks if the application has found it's configuration file or not.

How can this be done with wicket?


Thanks in advance!

Sven

Re: [Wicket-user] MarkupContainer.add() fails if log4j is enabled

2007-06-07 Thread Nili Adoram

If wicket policy prohibits isVisible() to depend on parent page,
you might as well make it final.
This is acceptable if you provide some other hook that may depend on
parent page.

It could be used in none logging code  also. The parent hierarchy doesn't

And it is confirmed in this article [1]:

Explaining Cognitive Lock-In: The Role of Skill-Based Habits of Use in
Consumer Choice

KYLE B. MURRAY
GERALD HÄUBL

We introduce and test a theory of how the choices consumers make are
influenced by skill-based habits of use—goal-activated automated
behaviors that develop through the repeated consumption or use of a
particular product. Such habits can explain how consumers become
locked in to an incumbent product. The proposed theory characterizes
how the amount of experience with the incumbent product, the
occurrence of usage errors while learning to use that product, and the
goal that is activated at the time a choice is made interrelate to
influence consumer preference. The results of three experiments
support the theory's predictions.

Re: [Wicket-user] MarkupContainer.add() fails if log4j is enabled

2007-06-07 Thread Nili Adoram

This breaks the concept of Model being evaluated when component is
rendered and not beforehand.
Moreover, this is an inconsistent behavior. System should have the same
behavior regardless whether log is enabled or not.
