Hi All,

I need to display localized messages that use the standard Java approach
to message parameterization. What is the best way to achieve that in Wicket
by using Wicket's Localizer class?

For example, my resource file may look like this:

WelcomePage.properties:

message=Welcome back, {0}! You last logged in at {1,time} on {1,date}.

The resulting message needs to look somewhat like this:

Welcome back, Bob! You last logged in at 15:45 on 03.05.2007.


Thanks!

Re: [Wicket-user] Add feedback message to internal error page.

there is always a Wicket Session.
That that session is stored or not in the http session is another question
(so yes the next request you could get a new one, if not stored previously)

Re: [Wicket-user] Updating formComponents on round trip


if you call form.process() then all the values of the form are processed and
stored to the model
(if the onselectionchange was done with a hidden form submit)
but only form.clear() should clear all input that was stored as a temp
variable in the form components
and then when you rerender it the real model values are rendered.

I tried form.clear() also, but it did not do anything. I can see strange
behaviour in my example :

I put process(); in onselectionChanged method.

Now when I start the page, first model is set and selected.

Now, when I update the textfield and click the other radio button, screen
is
refreshed , first model is updated.

But the textfields are not refreshed, and when I change the textfields
again
the first model is updated again.

I cannot understand it, becouse the selectedModel property is updated well
and both textfields have a selectedModel property as nested object model.

[Wicket-user] wicket vs. struts presentation

Hi all,

I am looking for help presenting wicket to my development team.

1-Has anyone out there had to defend wicket vs. struts and would you 
have any resources/links/presentations to pass this way to help in 
presenting wicket to our group?

2-Has anyone made any measurements/analysis of the code-base needed for 
identical application in wicket vs. struts(or any other framework)

3-Objectively, I am also looking for what wicket is weak at.

Re: [Wicket-user] Page Expiration when first clicking AJAX

2007-05-22 Thread Martin Funk

Hi Jonathan,

developing against a recent trunk I made a strange obeservation which
might be connected to this.

I have a page with several wicketAjaxGet calls. Some of em work fine.
The others behave strange, if clicked/called right after the page was
loaded they are answered with a Page Expired. If called after some other
fine working ones were called, those strange ones behaved just as expected.

Loading the page wicket complained with a:
ERROR org.apache.wicket.RequestCycle - the requested resource was not found
org.apache.wicket.WicketRuntimeException: the requested resource was not
found
at
org.apache.wicket.util.resource.WebExternalResourceStream.getInputStream(WebExternalResourceStream.java:99)

The page was delivered to the client without any warnings on the client
side.

The missing resource was a 'style.css'.

After I took care of that the Page worked fine, all wicketAjaxGet calls
worked as expected.
BTW, could someone please take care of:
https://issues.apache.org/jira/browse/WICKET-582

Debugging the problem I noticed that Page Expired was given cause of
line 114 in WebRequestCycleProcessor:
// the page is no longer the active page
// - ignore this request
processRequest = false;
Beyond this a breakpoint on AccessStackPageMap [line: 284] - put(Page)
showed that on initial load of the page the page itself was put on the
AccessStack and right after this an ExceptionErrorPage was put on that
stack.
The ExceptionErrorPage.id was the page.id incremented by one.

And this is the point were I got lost. Maybe someone else has a better
overview.

hope you have a magnifying glass with you then because that is ofcourse hard
to find ;)
But most people would say i guess use of session memory. But we manage that
for you
and in 1.3 this is much lighter then before. And i have seen struts apps
that did take
1MB of session memory and most of the time that where also leaks because of
session objects
that wheren't cleaned correctly because the developer needed some state from
Page X to Page Y.
but forgot to clean it up or the user never got to Page Y.

Hi,

Thanks for the feedback. We are contemplating doing some prototyping. I 
am currently implementing a small application within the group with 
wicket but it is not clear weather we will have the time to do the same 
for struts. On the other hand most people in the group have some level 
of experience with struts.


When is 1.3 being released?

2007-05-22 Thread Erik van Oosten


Hi Florian,

1- I am surprised you want to compare against Struts. Almost any modern web
framework will kick ass compared to Struts.

2- I know only of one. It is the first article on this page on the wiki:
http://cwiki.apache.org/WICKET/articles-about-wicket.html. It has a very
nice comparison of Wicket and JSF listings. Its a simple application, you
can easily image how to do it in Struts.

3- Wicket is weak at sites that need to handle millions of hits per minute
(not many frameworks are good at this). Wicket is also not very good if you
need absolute and complete control on the format of your URLs. These are
both extremes. I think Wicket will do very well for at least 90% of the web
applications.

Good luck,
Erik.

Check out:

http://static.raibledesigns.com/repository/presentations/ComparingJavaWebFrameworks.pdf

It gives a reasonable analysis of the frameworks out there. Note that 
Matt had only been using wicket for a weekend when writing this, and he 
admitted that the wicket cons that he mentioned there were actually 
pros, but he had to put some 'con's down!

As to what I wouldn't use wicket for? Wicket is a tool for building 
sites with complex user interfaces, to manage user interaction. If you 
needed to serve large amounts of content from a backend store to 
anonymous users, Wicket wouldn't seem the obvious choice (however it 
might be for the app that manages that content).

Hi,

the reason we are comparing to Struts is that that's one of the 
contender. We are not a web-app shop. We need a general purpose toolkit 
for intranet development. But since struts is so popular it's being 
pitted against wicket.

[Wicket-user] Feedbackmessages: extend by new type ALERT ?

2007-05-22 Thread Harald Gruber

hi all,

i was just wondering, if other users might have thought about the usefulness of 
extending FeedbackMessages by a new type ALERT
(and the according classes (Component.alert(message)...).

The reason for this would be, to provide the user special feedback shown 
through a javascript alert (or popup window)
and still have feedbackpanels for errorreporting in a page.

a simple component for showing alertmessages using javascript-alert is included 
in this message.

opinions welcome,

harald

The thing I took from Matt's talk was that even if you are going to use 
Struts, you shouldn't use Struts 1 - Struts 2 is a much better framework.

Thus, compared against struts itself, struts 1 is itself outdated.

wicket is a very good fit for intranet development.

[Wicket-user] Problem with wicket's WebSession objects. Memory leakage?

2007-05-22 Thread -Vlad-


Hi,all.
I've just noted the fact that after the session timeout time there is a call
to the MyWebApplication.sessionDestroyed(String sessionId) method, as it is
supposed to be. 
This method removes data from responce buffer, and that is all.
WebSession object remains in the JVM heap(Tested by means of JProfiler). And
the number of these objects grows as users' http sessions expire. How can I
remove all references to the wicket's webSession object when it expires?

[Wicket-user] Accessing Template Value of a Label


I'm not sure that what I describe here is possible, but if it is, I'd be
grateful if someone could point me in the right direction.

I'd like to allow template designers to give some default text for a lable,
e.g.:
label wicket:id=myLabelDefaultValue/label

And I'd then like to be able to either leave that text untouched, or append
it with a * character, depending on some other criteria that I can query
in the Page class.  But I can't find a way to make wicket retain the
template value (DefaultValue), never mind let me append other characters.

I was hoping (for example) that I could derive a class from Label and play
some tricks with onComponentTagBody/replaceComponentTagBody.  But it looks
like the templateValue (DefaultValue) is not available to me.

Am I missing something?  Or does Wicket throw away the Label text set in
the template before I have a chance to do anything with it?

Re: [Wicket-user] Problem with wicket's WebSession objects. Memory leakage?

who does keep the websessions? Can't you see that in your profiler?
we don't hold reference to the object itself anywhere in the code except
when handling a request itself.

You can change the template to:

DefaultValue label wicket:id=marked*/label

In the java code you do something like:

add(new WebMarkupContainer(marked).setVisible(condition));

Re: [Wicket-user] Accessing Template Value of a Label


Thanks for that Erik, I may well have to go with that if there are no other
suggestions.  But I'm still keen to learn if I can keep the Label text once
I add a wicket:id attribute to the label markup.

I may, for example, have to change (later in development) the label-marking
mechanism.  So, instead of adding a * character, I may have to colour the
label red, or add a border, or whatever.  So I was looking for a way to
centralise the label-marking mechanism in java, with no impact on the
markup, to make such a change as easy as possible.

I figured the best way to do this was just to make the whole label a wicket
component, so that I could manipulate it however I liked in java.  But doing
that seems to lose the label text altogether...

Re: [Wicket-user] Accessing Template Value of a Label


Thanks again Erik.  Using WebMarkupContainer rather than Label certainly
seems to help in terms of retaining the template text.  Butusing your
specified markup:
Default Label

Is there a way (without further altering the markup) to end up with output
which looks like:
Default Label*

I'd be happy with any non-DHTML mechanism at all (adding style as behaviour,
over-riding onComponentTagBody etc)!  Your original suggestion (having
another component whose visibility I control) means further markup
modification, which I'd like to avoid if possible.

This seems more like a stylesheet problem than a text generation
problem. Do /you/ need to change the way things are presented or your
designer?

In stylesheets you can add a * before or after some markup tag, or
make the border red, or have a line under it, or make the text larger.

Re: [Wicket-user] Problem with wicket's WebSession objects. Memory leakage?

2007-05-22 Thread -Vlad-


Thanks for the help, Johan.
I know that you stores wicket session in HttpSession(as atribute), provided
by container.
JProfiler shows that some PageMap keeps this. I've tried to get the root of
reference chain but failed due to constant JProfiler error. 
Can it be possible that some pagemap instance is stored not in the wicket
Session?
I have my custom transient object in wicket session, it is detached and
attached when the corresponing methods of the session is called. This object
contains some components(extends Component) and models(extends Model), which
I use on different pages (Is it a good practice?). 

And I also mentioned that 'sessionDestroyed' method doesn't involve calling
to 'session.invalidate()' method!

But...
I've overriden SessionStore, and I call session.invalidate() forcedly when
my SessionStore.onUnbind(String sessionId) method is invoked. After that
session is GC-ed. But I don't understand why?

In principle, I agree.  In practise, however, I understand that the css
selector that lets you append text is not supported by all browsers, and
specifically not by IE6 (I'd be delighted if I was wrong about this).  Which
is why I've been trying to find a maintainable Java solution...

Re: [Wicket-user] cannot find wicket-fvalidate

It should be in sourceforge's wicket-stuff repository somewhere.

Re: [Wicket-user] Problem with wicket's WebSession objects. Memory leakage?

pagemaps are also stored in the httpsession (not in the wicket session)

if the httpsession is destroyed then invalidate on the wicket session
shouldn't be called
because invalidate call on the wicket session does invalidate on the http
session, thats its purpose
but the http session is already invalidated (or it is busy
invalidating/destroying itself)

that call back is purely so that we can cleanup something that we store by
the session id
(the response buffers but that is very unlikely that they are kept around
and the request logger is notified)

use yourkit to profile:http://www.yourkit.com/

I know that you stores wicket session in HttpSession(as atribute),

JProfiler shows that some PageMap keeps this. I've tried to get the root

Can it be possible that some pagemap instance is stored not in the wicket
Session?
I have my custom transient object in wicket session, it is detached and
attached when the corresponing methods of the session is called. This
object
contains some components(extends Component) and models(extends Model),
which
I use on different pages (Is it a good practice?).

And I also mentioned that 'sessionDestroyed' method doesn't involve
calling
to 'session.invalidate()' method!

But...
I've overriden SessionStore, and I call session.invalidate() forcedly when
my SessionStore.onUnbind(String sessionId) method is invoked. After that
session is GC-ed. But I don't understand why?

Re: [Wicket-user] Feedbackmessages: extend by new type ALERT ?

I see it's a nice idea, but I'm afraid Wicket gets too messy if we'd
support two distinct message models like that. I don't know... maybe
you can open up a feature request for it and we can have it open for
discussion there? I think that the proper class to build something
like this in would be Session btw.

 a simple component for showing alertmessages using javascript-alert is

Not having touched IE in over a year I am of no use in this regard :).

 Which is why I've been trying to find a maintainable Java solution...

In the very least I would make it a custom component, so you don't
have that functionality spread across your whole app. Then when IE6
finally dies and withers away you only have to change one component

Re: [Wicket-user] wicket vs. struts presentation

 1-Has anyone out there had to defend wicket vs. struts and would you
 have any resources/links/presentations to pass this way to help in
 presenting wicket to our group?

Yeah, a million times now :) Seriously, I think you can find quite a
bit googling (use model 2 vs wicket or something) or searching the
mailing list.

In a nutshell, imho disadvantages of Struts (and all model 2
frameworks like SpringMVC etc) are:
* no reuse
* no state management (making things like pageable lists etc and self
contained components tedious)
* no good abstractions (just actions in the scope of requests)
* no clean separation of presentation and logic (as with Struts you'd
use JSP or something similar)
* encourages bad coding practices (lots of hacks needed to get
something of any complexity done and coding with actions and page
flows is basically back to procedural programming again).

etc etc

 3-Objectively, I am also looking for what wicket is weak at.

It depends on how familiar you are with Wicket and whether you think
the alternatives are better. If you like to script in pages (like
you'd do with JSPs) Wicket is probably not for you. More of a taste
matter though. Then there's the fact that by default it uses server
memory. But that's easy to get around, and imho even if you use
stateless pages, forms and links for your whole application with
Wicket, which is a less nice and limited way to use Wicket, you'd
still have a nicer programming model than, say, Struts.

My2c (I can go on for a bit, but out of time now ;) )

Re: [Wicket-user] Exception Strategy in 1.3

2007-05-22 Thread Rüdiger Schulz

Make a subclass of WebRequestCycle, and override onRuntimeException().
Works like a charm for me.

2007/5/22, craigdd [EMAIL PROTECTED]:

 True the wicket session is mandatory, thanks for pointing that out.

 As for my question though, I'm looking for the best way to implement this
 strategy.  I could override the respond method in RequestCycle, but I'd have
 to rewrite the given logic, which most of it I want.  I'm wondering if there
 are any other hooks that I can implement that leaves the respond method
 alone but have the exception and internal page available.

Re: [Wicket-user] Pattern for seperation of Java and Html - Comments Welcome

Well, it's something you can quite easily do yourself. See
org.apache.wicket.examples.customresourceloading. Unless I don't
understand what you mean, it doesn't sound like something that should
be a generic facility in Wicket to me.

In certain cases for content such as press releases or other user generated

- Extend one of the existing containers such as WebComponent.
- This component when inserted in a page would get the actual source html
from a Page Parameter such as http://host/wicketapp?RealPage.html or
http://host/wicketapp?content=RealPage.html .
- RealPage.html identifies the location of the content to be inserted.

In this way I can create a wicket template for the main containment page and
then use it typically to insert the user generated content. This gives me
the flexibility I want without having to generate a class for all included
content.

Am I missing something here?

 i prepended http://www.w3.org/TR/xhtml1/DTD/ in the front of
 the filename.

 Maybe it would be useful to fix these directly in the

 Then I just added wicket: attributes to custom attributes

Re: [Wicket-user] Pattern for seperation of Java and Html - Comments Welcome

2007-05-22 Thread mchack

Thanks for the reply. Not suggesting it should be part of the main
distribution. I am new to the framework and was trying to see if what I
proposed made sense. I want to make sure that I don't hinder or create
barriers to content creation on our portal and wanted to do it in a manner
that made sense. Maybe there are other ways to manage separation of
concerns.

In general are their recommended best practices regarding coordination and
workflow between the pure HTML designers and Java coders? In the component
model, seems like an HTML designer will come up with basic look and feel,
CSS, etc. and then the people on the framework side will
refactor/componentize the markup. At this point the original markup may
now be generated by an OO refactoring involving a number of new
pages/components to insert dynamic content/behavior. The original design is
now split into a variety of new pages and will no longer be readily
accessible to the original designer as they now have to work on a variety of
fragments. Any references to how to keep the HTML development happy would be
appreciated.

Thanks

if you use ajax, then you need to be sure that there is already a markupID

WebMarkupContainer for example however) and that the target is then updated
accordingly...

Re: [Wicket-user] newbie - getting a null AjaxRequestTarget


if you are using ajaxfallbacklink and get a null target then that means the
fallback was used, so the browser doesnt support ajax/javascript. that is
the whole point of ajaxfallbacklink, your impl should look like this

onclick(target) {
 dosomething();
 if (target!=null) {
   // ajax
   processajaxtarget(target);
  } else {
 //falback
 processregularroundtrip();
  }

Re: [Wicket-user] Exception Strategy in 1.3

2007-05-22 Thread craigdd


Overriding the onRuntimeException does not work because you don't have access
to the page that you are directing to.  The page parameter in this method if
the context from where the exception was thrown.

 True the wicket session is mandatory, thanks for pointing that out.

 As for my question though, I'm looking for the best way to implement this
 strategy.  I could override the respond method in RequestCycle, but I'd
 have
 to rewrite the given logic, which most of it I want.  I'm wondering if
 there
 are any other hooks that I can implement that leaves the respond method
 alone but have the exception and internal page available.

[Wicket-user] problem with Ajax and rendering on trunk version

2007-05-22 Thread Xavier Hanin

Hi,

I've just upgraded my 1.3 beta 1 version to a personnally build
snapshot version based on revision xxx to fix a problem related to
Ajax and Page Expired, and the problem I had before is gone. Great!

But now I've another strange problem. I get the following error message:
18:49:19.245 [btpool0-2] ERROR org.apache.wicket.RequestCycle - The
component(s) below failed to render. A common problem is that you have
added a component in code but forgot to reference it in the markup
(thus the component will never be rendered).

1. [MarkupContainer [Component id = progressBarStylesheet, page =
org.xoocode.xooctory.web.pages.dashboard.Dashboard, path =
2:projects-panel:projects:6:leftTimePanel:progressBar:progressBarStylesheet.StyleSheetReference,
isVisible = true, isVersioned = false]]

The problem is that the component is properly added, and it worked
before upgrading, so...

So I've tried to track down the problem, and I've not found the source
of the problem. As a workaround I disable check rendering with:
getDebugSettings().setComponentUseCheck(false);
Then everything works properly, and the component (a style sheet) is
properly rendered.

Let me explain a little bit more the situation in which the problem occurs.
The component which is causing the problem is a StyleSheetReference
added to a panel. The markup contains the corresponding link in a
wicket:head section.
The panel is invisible when the page is loaded, but then I use an ajax
link to trigger an action, which later triggers the visibility of this
component to true. Then this component is refreshed by an AjaxTimer
(actually I use wicket-contrib-push, but I don't think it really makes
a difference, since it's using a simple AbstractAjaxTimerBehavior
underneath). And that's when the component is rendered that the check
rendering is failing. Some analysis shown that there's a
StyleSheetReference with the good id in the renderedComponent
attribute of Page, but it isn't the exact same StyleSheetReference
instance as the one checked by the checkRendering method. For the
moment I haven't managed to really see why I have two instances, what
doesn't help is that it seems that when I debug, the problem goes away
depending on the occurence of other timer based ajax requests.

Do any of you have already faced this problem, or has any idea of how
it could come from?

Re: [Wicket-user] Problem with wicket's WebSession objects. Memory leakage?


WicketSession.invalidate triggers the httpsession.invalidate that triggers
the destroy

So the destroy shouldn't trigger wicketsession.invalidate because its the
other way around

what you can do is listen to the SessionStore.unbind() or have a special
HttpSessionUnbinding listener
that calls your close() method on the wicket session or something like that.

but SessionStore.unbind() shouldn't call WicketSession.invalidate() thats
like driving the wrong way

On 5/22/07, -Vlad- [EMAIL PROTECTED] wrote:



Ok, but I need my wicket session invalidate() method to be called when
httpSession expires.
I had a look at the source (1.2.6) and what I
saw(AbstractHttpSessionStore.class, line 97) is a call
'SessionStore.unbind(String sessionId)' when HttpSession expires. This
method (in the AbstractHttpSessionStore.class) calls
Application.sessionDestroyed
than call empty 'onUnbind(sessionId)' method. So there are no calls to
httpSession.invalidate() method and to
wicketSession.invalidate();
My wicket  session overrides invalidate method:
public void invalidate() {
super.invalidate();
close();
}
super is the WebSession class, and its invalidate method is:
public void invalidate()
{
sessionInvalidated = true;
}
So as far as I understand there is no extra call 'httpSession.invalidate
()'.
What do you think about this?

[Wicket-user] setVisible on Fragment with AjaxFormComponentUpdatingBehavior

2007-05-22 Thread Flavius


I am trying to setVisible on a Fragment using the
AjaxFormComponentUpdatingBehavior object.
It doesn't seem to work.  I've also tried this with a Panel and that's not
working either.

However, if I use a component, like a TextField, that works.

In my java, this is the pertinent code for my Form:

DropDownChoice dropDown = new DropDownChoice(dropDown, new Model(),
choiceList);
add(dropDown);

final WebMarkupContainer container = new WebMarkupContainer(container);
container.setOutputMarkupId(true);

final Text2Fragment text2Fragment = new 
Text2Fragment(text2Fragment,
text2FragmentId);
container.add(text2Fragment);
add(container);

dropDown.add(new 
AjaxFormComponentUpdatingBehavior(onchange)
{
protected void onUpdate(AjaxRequestTarget 
target)
{

target.addComponent(container);
text2Fragment.setVisible(false);
}
}); 

My fragment:
private class Text2Fragment extends Fragment
{
public Text2Fragment(String id, String markupId)
{
super(id, markupId);
TextField text2 = new TextField(text2);
add(text2);
}
}



My HTML:
tr
tdDropDown:/td
tdselect wicket:id = 
dropDown/select/td
/tr   
tr
tdText 1/td
tdinput wicket:id=text1/td
/tr
--spaces in span are for nabble 
sp an wicket:id=container 
sp an wicket:id=text2Fragment/sp 
an
/sp an

tr
tdText 3/td
tdinput wicket:id=text3/td
/tr

My Fragment:

wicket:fragment wicket:id=text2FragmentId
tr
tdText 2/td
tdinput wicket:id=text2/td
/tr
/wicket:fragment

If I put the text2 TextField in place of the fragment, the control
successfully
disappears.  I want a fragment so I can also remove labels, et al.

I'd appreciate any feedback on what I'm doing wrong.

3. We have the javascript to intelligently place the div close to the

i have something similar to this in my project. basically what it is is a
border that has an anchor tag and a div inside of it. the border:body tag is
inside this div. the div has the necessary styles (position:absolute, etc).
the border component implements iheadercontributor and through that writes
out the necessary javascript to connect the anchor tag with the div.

how to use it, simple. you add the border anywhere in your markup, and to it
you add a panel/fragment which will appear in the initially hidden div. and
you are done, nothing more to it it is totally reusable anywhere. i am
leaving on vacation tomorrow, maybe when i get back i will contribute it to
wicket-minis, unless you beat me to it :)

BTW, on the previous link you can see the My Tasks section for what I'm

there a method that then gets called on objects passed into the target? I'm

By viewed range I simply mean that the panel displays the index range of

Is there an easy way to use this with an ordered list as opposed to a

I'm trying to determine if a (possibly overcomplicated) DataTable with a

[Wicket-user] How to update AjaxTabbedPanel tab with new data

2007-05-22 Thread wicket0123


We are using AjaxTabbedPanel to display data.  We don't want to pre-load all
the data at star up. We want to load the tab's content when user clicks on
the tab.  So, we decided to use AjaxTabbedPanel.  We are using AbstractTab. 
Each tab represents a category, so we hold the category id on the tab panel.

public class MyAjaxTabbedPanel extends AjaxTabbedPanel {

private String name;  // this is the ajaxtabpanel name
List tabs;  // this holds the list of tabs

public MyAjaxTabbedPanel (String id, String nameTag, List tabsList) {
super(id, tabsList);
name = nameTag;
tabs = tabsList;
}
  
protected  void onAjaxUpdate(wicket.ajax.AjaxRequestTarget target) {

  AbstractTab selectedTab = (AbstractTab)
tabs.get(getSelectedTab()); 

  // took me a while to figure out that 'panel' is hardcoded
as the panel id
  MyTabPanel tabPanel = (MyTabPanel )
selectedTab.getPanel(panel); 

  // data from service layer
  List newTabList =
MyService.getSomethingBasedOnCategoryId(tabPanel.getCategoryId());

 // remove existing components; otherwise, complain about wicket:id
already exists
 // add new one
 tabPanel.removeComponents();   
 tabPanel.addComponents(newTabList);


 // refresh the component
 target.addComponent(this); 

}

}

The above code will run w/o errors, but UI doesn't refresh.  I'm suspecting
i'm not refreshing the correct component.  As you can see, the components
are added on the MyTabPanel class.  I appreciate if someone could point me
to the right direction of show me some examples on how to dynamically update
tabs content.

Re: [Wicket-user] Updating item range for ajax pager


what i meant was see how it constructs the message. it overrides
model.getobject(), which is called everytime the component needs to render.
you should read the models page on the wiki.

Is there an easy way to use this with an ordered list as opposed to a

I'm trying to determine if a (possibly overcomplicated) DataTable with a
NavigatorLabel is a better solution than the onAjaxUpdate()
target/container

We are using AjaxTabbedPanel to display data.  We don't want to pre-load

AbstractTab.
Each tab represents a category, so we hold the category id on the tab
panel.



dont really understand what you are trying to do/what problem you have. even
the non-ajax tabbedpanel does not load all the data on start up. it only
loads the data once the user clicks the tab.

add(new AbstractTab(new Model(tab1) { Panel getPanel() { return new
Panel1(); }});
add(new AbstractTab(new Model(tab2) { Panel getPanel() { return new
Panel2(); }});


when the tabbed panel renders it will default to tab1, so panel1() will be
created because getpanel() will be called on the first itab. then when user
clicks on tab2 panel2 will be created because getpanel() will be called on
the second itab.

[Wicket-user] JRuby + Wicket?

2007-05-22 Thread Mike Pence

Hello all.

I have been doing Rails for about a year and a half now, and I am
wondering if anyone has worked through combining Wicket with JRuby?
Seems like the killer combo to me...

Best,
Mike Pence

Re: [Wicket-user] Exception Strategy in 1.3

You can return the page you want to be displayed and have full
control. I know the API currently is non-obvious; I complained about
this in another thread.

For example, this is what I'm using for the project I'm working on:


public Page onRuntimeException(Page page, RuntimeException e) {

if (e instanceof AuthorizationException) {
return super.onRuntimeException(page, e);
} else if (e instanceof PageExpiredException) {
Ts4Session session = Ts4Session.get();
if (session.isTemporary() || session.getUserId() == 
null) {
// this was an actual session expiry
log
.info(session expired and 
request cannot be honored, cycleId: 
+ cycleId);
return super.onRuntimeException(page, e);
} else {
log.error(unable to find page for an active 
session!);
// hmmm, we have a logged in user, but the page 
could not be
// found. Fall through to display an error page 
or exception
// page
}
}

if (Application.DEPLOYMENT.equals(Application.get()
.getConfigurationType())) {
return new ErrorPage(e, page, cycleId);
} else {
return new ExceptionErrorPage(e, page);
}
}

eelco

 Overriding the onRuntimeException does not work because you don't have access
 to the page that you are directing to.  The page parameter in this method if
 the context from where the exception was thrown.
