Re: [Wicket-user] programmatic access to a wicket site

[Lowell Kirsh]

Really? What about the getResponseCode() method?

http://java.sun.com/j2se/1.4.2/docs/api/java/net/HttpURLConnection.html#getResponseCode()

But I'm sure if you are right about not being able to get it from that
class, my clients will use the jakarta (or other) client instead.

So the idea of using a POS (plain old servlet ;-) did cross my mind,
but I was hoping to make my web page serve both purposes so that I
could minimize the amount of coding I would have to do. Hopefully I
can actually use the AbortWithWebErrorCodeException to serve this
purpose.

Re: [Wicket-user] Wicket-stuff GMAP

[Nino Saturnino Martinez Vazquez Wael]

Hi Iulian

I'll start to "upgrade" the current 1.2 branch to be using the newest 
version of googlemaps. That will mean that I'll add support for

these controls(I think two of them are already supported):

* |GLargeMapControl| - a large pan/zoom control used on Google Maps.
  Appears in the top left corner of the map.
* |GSmallMapControl| - a smaller pan/zoom control used on Google
  Maps. Appears in the top left corner of the map.
* |GSmallZoomControl| - a small zoom control (no panning controls)
  used in the small map blowup windows used to display driving
  directions steps on Google Maps.
* |GScaleControl| - a map scale
* |GMapTypeControl| - buttons that let the user toggle between map
  types (such as Map and Satellite)
* |GOverviewMapControl| - a collapsible overview map in the corner
  of the screen

Also I'll be looking into markers manager and see if I can add that.

I plan todo this before you come back from your vacation, so that you 
may continue upgrading to the 1.3 branch.

regards Nino

Re: [Wicket-user] programmatic access to a wicket site

[Erik van Oosten]

Yeah, weird it is. Perhaps that method only returns something when there 
was a result code representing a successful retrieval, so anything in 
the 200-299 range. I am positively very sure that non-2XX codes will 
trigger an IOException.

Regards,
 Erik.

Strange, it says in the javadoc that it can return 404, for example.
But it also says it'll throw an exception on a bad connection.
Confusing indeed.

Thanks Vincent but unfortunately it doesn't work for me. I get the same

Please let me know if you need more info about the errors.
  


Ok, so can you give me a little code snippet, or a mini sample code

Do you use firebug(https://addons.mozilla.org/fr/firefox/addon/1843)? If

Is this version in a good state or is it my fault? Are there any

Thanks,

Dragos,

This Error has been fixed but build failed since a long time. Try to 
get the last jar in the maven repo 
http://wicketstuff.org/maven/repository/org/wicketstuff/wicketstuff-dojo/1.3.0-SNAPSHOT/ 
(from today ;) )


I think the problem has been solved

I tried to use the corresponding version (1.3.0-incubating-SNAPSHOT) 
from 
http://wicketstuff.org/maven/repository/wicket-stuff/wicket-contrib-dojo/1.3.0-incubating-SNAPSHOT/ 
but it seems is still referencing the old package names (without

The right location is:
http://wicketstuff.org/maven/repository/org/wicketstuff/wicketstuff-dojo/1.3.0-SNAPSHOT/

One day we'll need to clean the Maven repo!  Several users are
confused with the various leftovers.  Should we just wipe out the
whole stuff?  Then we can fire Bamboo to rebuild everything.

Re: [Wicket-user] Wicket-stuff GMAP

[Nino Saturnino Martinez Vazquez Wael]

Eeek. I have to use java 1.4, we need to have a branch for 1.4 and 
aswell for it to work for me.

I've already managed to update to gmap2 and add below features in the 
1.5 version.
I've also converted the 1.5 to an 1.4 so when I get commit access I will 
make the to versions.

Currently Im looking at making custom GIcons, this feature fill come 
into the 1.4 first as this is my primary focus. When I've added the 
gmarkermanager aswell I'll convert the stuff to 1.5

That's very true, and there is a JIRA issue for this:

PackageRequestTargetUrlCodingStrategy should interrupts the cycle

[Wicket-user] getVariation and extended panels

[Joshua Lim]

Hi

I have got a SuperPanel class that extends Panel, I have a few variations of
html for this SuperPanel and am overriding the getVariation() method for to
get what I want ...that's all good.

Then I wanted to add a ChildPanel extending SuperPanel. and also I would
like to have ChildPanel to have also a few variations hence giving me more
flexibility in generating dynamic panels as a result...

getVariation() gets resolved at the ChildPanel level only. since overriding
the getVariation on ChildPanel hides SuperPanel.getVariation().

Am I stretching this too far?? :p and should just work with one variation
per component hierarchy

Re: [Wicket-user] programmatic access to a wicket site

[Frank Bille]

Perhaps take a look at:

http://svn.apache.org/viewvc/incubator/wicket/trunk/jdk-1.4/wicket/src/main/java/org/apache/wicket/markup/html/pages/InternalErrorPage.java?view=co

specially in the configureResponse section.

Re: [Wicket-user] Preventing DropDownChoice to reload the choice list on submit

[Dimitrio]

Thanks to everybody the replies!

I played with form components for awhile and in particular with
DropDownChoice and could get it to do exactly what I needed.

Just to remind -- I wanted to prevent the DropDownChoice from loading the
entire list of choices (countries) on submit, but to only load the entity
selected by the user by some indexed unique field and assign it to the
object being edited (city).

DropDownChoice loads the list of choices in the
AbstractSingleSelectChoice.convertValue(String[]) method which is final.
That method is called from FormComponent's convert() which is also final.
However, if a form component has been provided with a type,
convertValue()is not called, and instead a converter is used.

So, here is what I did:

1. Wrote a CountryConverter:

public class CountryConverter extends SimpleConverterAdapter {
   public Object toObject(String value) {
   return ServiceUtils.getAddressService().getCountryByCode(value);
   }

   public String toString(Object value) {
   return String.valueOf(value);
   }
}

Not sure about the purpose of toString method here. Initially I thought it
would be passed a Country instance and would return a String to be rendered
as the value for  (an ISO code), but it looks like an
IChoiceRenderer is used for this purpose. toString was being invoked with
String representations of my countries.

2. Wrote a CountryChoiceRenderer:

public class CountryChoiceRenderer implements IChoiceRenderer {
   public String getIdValue(Object object, int index) {
   Country country = (Country) object;
   return country.getIsoCode();
   }

   public Object getDisplayValue(Object object) {
   Country country = (Country) object;
   return country.getName();
   }
}

3. Implemented a DropDownChoice as an inner class of my panel:

   class CountryChoice extends DropDownChoice {
   public CountryChoice(String id) {
   super(id);
   setChoices(new LoadableDetachableModel() {
   protected Object load() {
   return ServiceUtils.getAddressService
().getAllCountries();
   }
   });
   setRequired(true);
   setChoiceRenderer(new CountryChoiceRenderer());
   setType(Country.class);
   }

   public IConverter getConverter() {
   return new CountryConverter();
   }
   }


Here is what happens on submit:

1. Form processing begins and eventually FormComponent.convert() is called
on my CountryChoice.
2. FormComponent.convert() sees that the component has a type (Country.class)
and instead of calling convertValue() calls my converter.
3. My converter selects a country by ISO code.
4. The City instance is assigned the selected country and then
saveOrUpdate()'d.

5. If I redisplay my panel, the country list will, of course, be loaded
during the rendering phase. If I redirect to some other page, the country
list will not be loaded -- just as I needed.


I would like to see some comments regarding this approach. What do you think
about it? Can you suggest any improvements? Would consider using it in your
Wicket application? Is it "the Wicket way" of doing things?


Best regards,

Dimitrio

there is wicket-phonebook project in wicket-stuff that shows

your dropdownchoice should use a loadable detachable model, that way the
list is loaded once per request

add(new dropdownchoice("city", new loadabledetachablemodel() { load() {
return dao.listcities(); }}));

that answers question 1 and question 2 - the data will be reloaded in
onsubmit() since that is a new request, but that same data will be used for
rendering as well.

I want to parse username and its value and address value. Is it possible in
wicket? If Yes How?

Thanking You

Re: [Wicket-user] wicket-contrib-dojo for wicket 1.3.0

[Dragos Bobes]

Hi Vincent,

Thanks again for your interest in helping me.
I think I found the problem. I started a new project and the dojo stuff 
was working there. When I compared the two projects one of the 
differences was that in one of them (where dojo wasn't working) I was 
mounting the application's pages to a specific url:

mount("/pages", PackageName.forPackage(Home.class.getPackage()));

When I removed the mount line dojo stuff worked fine.
I've attached a small project in a working state. If you uncomment the 
mount line in the MyApplication.java you'll see that the dojo page 
doesn't work anymore.

I hope this helps,
Dragos

[Wicket-user] div id problem

[Bernatet Mathieu]

Hi,

I try to apply css style on several div but wicket changes their id
attributes defined in the html file.
I have 3 custom panels that contain a DataView and I want to refresh
them with ajax, so I make a call to setOutputMarkupId() method. This
call changes the id defined in html file.
I add an AttributeModifier to force the use of the defined id, that
works but now ajax refresh don't work.
What I'm doing wrong?

code:

dashboard.html:

...







---

viewPanel.html:



[agents 
navigator]



ViewPanel.java:

public class ViewPanel extends Panel {
private static final long serialVersionUID = 1L;

public ViewPanel(String id, DataView dataView, int 
itemsPerPage) {
super(id);
setOutputMarkupId(true);
add(dataView);
dataView.setItemsPerPage(itemsPerPage);
add(new AttributeModifier("id", true, new Model(id)));
add(new FancyPagingNavigator("navigator", dataView));
}
}
-

Dashboard.java:

public class Dashboard extends WebPage {
public Dashboard() {
...
add(new ProjectsPanel("projects-panel", projects, 5));
add(new AgentsPanel("agents-panel", scheduler, 5));
add(new QueuePanel("builds-panel", scheduler, 5));
}
}

[Wicket-user] wicket-contrib-push: bad dependency

[Xavier Hanin]

Hi,

I think there is a problem with the current wicket-contrib-push pom: the
dependency on dojo is:
   
   org.wicketstuff
   dojo
   1.3.0-SNAPSHOT
   
but I think it should be:
   
   org.wicketstuff
   wicketstuff-dojo
   1.3.0-SNAPSHOT
   
according to current wicket-contrib-dojo pom.

Or am I missing something?

Re: [Wicket-user] XML Parsing

[Lennaert van der Linden]

Hello Edward,

I am new to wicket myself and wouldn't be surprised if it contained it's 
own XML parsing and binding library. But you probably don't want to rely 
on it, as it the wicket developers may decide to go for another library.

You could look into:
- jdom (haven't used this, but it looks quite easy to use from the FAQ)
- Java DOM API (the w3c standardized way of reading XML files)
- jaxb (generates marshalling/unmarshalling code from an XML schema. You 
unmarshall an XML file and then you get to access the information as 
PersonalInformation.getUserName() ).

Re: [Wicket-user] webPages variableFlow, backButton, theSmartAndCorrectWay?

[Johan Compagner]

in 1.2 you really need to hold on to the pages else the can fall out of the
page map and then you can never restore them
Ofcourse if the state is just some data you could keep the model and rebuild
the page with that model if needed?

Re: [Wicket-user] How to find pages where we forgot to use detachable models?

[Johan Compagner]

what you can do is in detach you try to serialize all the pages that you
render
and test if it serializes. Or test if there are no special objects being
written that you don't expect to be written
(have a custom ObjectOutputStream for that)

als wicket 1.3 does have now a special object output stream checker which
points you exactly what field of what
object is not serializeable

johan

On 5/10/07, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote:


<>

Currently all my Wicket pages are using chained property models +
detachable models for dynamic content.  This works great.

However, recently I discovered that one of my pages was getting a
serialization error.  Turns out that the page in question was not using a
detachable property model, and so its object graph was being serialized.
The default Wicket serialization was failing and causing an exception and
backtrace.

My question for the list is this:

Is there a Wicket feature that can identify which pages are NOT using
detachable models for dynamic content?  It would be nice if there was a
way that Wicket could flag whenever we're serializing model objects
(possibly big object graphs of model objects).

In other words, it would be handy to find non-detachable dynamic models
without reading line-by-line through the source code of every single
Wicket page.

Thanks for any help/info.

Re: [Wicket-user] How to find pages where we forgot to use detachable models?

[Eelco Hillenius]

You do that with org.apache.wicket.util.lang.Objects.cloneObject(yourPage)

Re: [Wicket-user] div id problem

[Matej Knopp]

Right now, when you set outputmarkupid on component wicket doesn't
honor the id specified in markup. One of the reasons is that when you
use the component twice, the id is no longer unique. In you case I
suggest you use css class instead of id to assign stylesheet to your
elements.

[Wicket-user] newbie creating an expandable tree node with no children

[sf]

How can I create an expandable node when the node doesn't have any children.
it seems as if the '+' sign is added automatically only when children exist
(I am implementing a lazy loading tree, the children will be added only when
the user expands the node)?


Thanks
Shula

[Wicket-user] wicket-contrib-push: design discussion

[Xavier Hanin]

Hey WCP folks,

I've just started using wicket-contrib-push, and I feel a bit at home with
all these comments with my name as the author :-)

I would like to discuss the design with you. For the moment there interfaces
implemented by both timer and comet implementations, but it's not that easy
to switch. Indeed if you look at the examples they are very implementation
dependent.

So my proposition is to introduce another interface, called IPushService,
which would allow both to publish and receive events. You would have a timer
and cometd based implementations for the moment, but you could rely on the
interface only the interface for push related operations.

I attach a patch on current code base with an implementation of what I'm
thinking about, it may help you better see what I mean.

WDYT?

It is a very good idea. It will allow users to have less configuration 
to do. I like that because it is

   - easier to use
   - easier to switch

I understand that if the id is specified in the panel markup
(ViewPanel.html) , but it is not the case here.

ok, I didn't use a class attribute for my div so I can use it now.

Hi Shula,
You need to override isLeaf() in your TreeNode impl to return true.

Hey WCP folks,

I've just started using wicket-contrib-push, and I feel a bit at home with
all these comments with my name as the author :-)

I would like to discuss the design with you. For the moment there
interfaces implemented by both timer and comet implementations, but it's not
that easy to switch. Indeed if you look at the examples they are very
implementation dependent.

So my proposition is to introduce another interface, called IPushService,
which would allow both to publish and receive events. You would have a timer
and cometd based implementations for the moment, but you could rely on the
interface only the interface for push related operations.

I attach a patch on current code base with an implementation of what I'm
thinking about, it may help you better see what I mean.

WDYT?


It is a very good idea. It will allow users to have less configuration to
do. I like that because it is
- easier to use
- easier to switch

+1



OK, so now that I'm a wc-push committer I guess I can check it in. I will
also review the examples, especially the two chats implementation, to show
easy it is to switch.

And since you agree with this change, I'm wondering if the two actual
behavior implementation should implement IPushBehavior. Indeed I think it
can confuse users, because passing one of those two implementations to the
IPushService#addPushBehavior(Component component, String channel,
IPushBehavior behavior) doesn't make sense.

So I suggest to remove this interface impl from the two behavior
implementation, rename IPushBehavior in IPushListener, and rename
#addPushBehavior(Component component, String channel, IPushBehavior
behavior) in #addPushListener(Component component, String channel,
IPushListener listener)

WDYT?

[Wicket-user] DataView: fixed number of items per page

[Bernatet Mathieu]

Hi,

I'm using dataView, and for design issues I want 5 items per pages
even if they are empty whereas setItemPerPage() method only defines a
maximum number of items to be displayed.
Any suggestions?

I think I could use the IDataProvider.iterator(first, count) and

I have got a SuperPanel class that extends Panel, I have a few variations

Then I wanted to add a ChildPanel extending SuperPanel. and also I would
like to have ChildPanel to have also a few variations hence giving me more
flexibility in generating dynamic panels as a result...

getVariation() gets resolved at the ChildPanel level only. since
overriding the getVariation on ChildPanel hides SuperPanel.getVariation().

Am I stretching this too far?? :p and should just work with one variation
per component hierarchy

One of the requirements of the site that I'm building is that oneof

it. They would know whether they'd succeeded or not by inspecting the
http status code returned. Since this is just a regular page  of the
site, when the call is successful a web page is rendered and returned.
In this case it would be ignored. But when there is an error, I'd like
to relay that to clients.

One thing I've been trying to do (without any success) is to throw an
AbortWithWebErrorCodeException from my constructor with a non-200 code
and a message. Now supposing that it works, I'd like to know how a
client could extract the message from the response. Is it sent as a
header, the entire body, or part of the body?

And if there is another approach that would work in my case, I'd love
to hear about it.

Indeed, it makes more sense like that. To be consistent, should we change
all Push* in Channel*?

Re: [Wicket-user] Force page refresh after Ajax request completes?

[dukejansen]

Yup. That's why I was trying to do it using
target.appendJavascript("window.location.reload()") instead of doing the
setResponsePage server side...? Since I'm appending that Javascript AFTER
the 'close modal window' call, it seems like it should be able to close the
modal window client side, THEN call my javascript to refresh the page,
without the warning, since the modal has been closed.. ?

Re: [Wicket-user] Preventing DropDownChoice to reload the choice list on submit

[Igor Vaynberg]

ichoicerenderer needs an id and a display value, the converter only has a
single tostring - would that be used for id or for display value?

Thanks to everybody the replies!

I played with form components for awhile and in particular with
DropDownChoice and could get it to do exactly what I needed.

Just to remind -- I wanted to prevent the DropDownChoice from loading the
entire list of choices ( countries) on submit, but to only load the entity
selected by the user by some indexed unique field and assign it to the
object being edited ( city).

DropDownChoice loads the list of choices in the
AbstractSingleSelectChoice.convertValue(String[]) method which is final.
That method is called from FormComponent's convert() which is also final.
However, if a form component has been provided with a type, convertValue()
is not called, and instead a converter is used.

So, here is what I did:

1. Wrote a CountryConverter:

public class CountryConverter extends SimpleConverterAdapter {
public Object toObject(String value) {
return ServiceUtils.getAddressService().getCountryByCode(value);
}

public String toString(Object value) {
return String.valueOf(value);
}
}

Not sure about the purpose of toString method here. Initially I thought it
would be passed a Country instance and would return a String to be rendered
as the value for  (an ISO code), but it looks like an
IChoiceRenderer is used for this purpose. toString was being invoked with
String representations of my countries.

2. Wrote a CountryChoiceRenderer:

public class CountryChoiceRenderer implements IChoiceRenderer {
public String getIdValue(Object object, int index) {
Country country = (Country) object;
return country.getIsoCode();
}

public Object getDisplayValue(Object object) {
Country country = (Country) object;
return country.getName();
}
}

3. Implemented a DropDownChoice as an inner class of my panel:

class CountryChoice extends DropDownChoice {
public CountryChoice(String id) {
super(id);
setChoices(new LoadableDetachableModel() {
protected Object load() {
return ServiceUtils.getAddressService
().getAllCountries();
}
});
setRequired(true);
setChoiceRenderer(new CountryChoiceRenderer());
setType(Country.class);
}

public IConverter getConverter() {
return new CountryConverter();
}
}


Here is what happens on submit:

1. Form processing begins and eventually FormComponent.convert() is called
on my CountryChoice.
2. FormComponent.convert() sees that the component has a type (
Country.class) and instead of calling convertValue() calls my converter.
3. My converter selects a country by ISO code.
4. The City instance is assigned the selected country and then
saveOrUpdate()'d.

5. If I redisplay my panel, the country list will, of course, be loaded
during the rendering phase. If I redirect to some other page, the country
list will not be loaded -- just as I needed.


I would like to see some comments regarding this approach. What do you
think about it? Can you suggest any improvements? Would consider using it in
your Wicket application? Is it "the Wicket way" of doing things?


Best regards,

Dimitrio

Re: [Wicket-user] How to find pages where we forgot to use detachable models?

[Igor Vaynberg]

make sure you call super.detach() first though

what you can do is in detach you try to serialize all the pages that you

als wicket 1.3 does have now a special object output stream checker which

Better, but the nitpicker in me says that 'Listeners' wouldn't

I understand that if the id is specified in the panel markup
(ViewPanel.html) , but it is not the case here.



it might not be the case, but how is wicket supposed to know that? also what
if you put that component into a repeater? it will also have non unique ids.
i think there are so many different ways to break this that i always
advocated of never honoring markup's id attr if setoutputmarkupid is called.

What do you mean by participate? My proposition is to make listeners only
listeners, doing nothing but listening to events and reacting, by for
example sending javascript to the client.

Here is a sample use in a page:
   pushService.addChannelListener(this, "channel", new
IChannelListener() {
   public void onEvent(String channel, Map datas,
IChannelTarget target) {
   target.addComponent(container);
   }
   });

The two current implementation of IPushBehavior would stay behaviors, used
by the IChannelService implementation, but not visible to the API user.

Does it make sense?

Re: [Wicket-user] DataView: fixed number of items per page

[Igor Vaynberg]

that will work. or you can create your own dataview :) look at DataViewBase,
its only a few lines of code, so you can create your own subclass of
AbstractPageableView where setitemsperpage works like you want.

So what is the recommended best practice: ask web designers to use class
instead of ids on dynamic components (maybe not always possible), or
encapsulate a dynamic component in a static one with an id under control of
the web designer?

[Wicket-user] session authentication

[eddmosphere]

Hi there!

I having a bit of trouble implementing session authentication in my
application. That is, I haven't quite figured out how to control
authentication page access. 

I would really appreciate if someone could send me a simple application with
a Login Page that provides access to a Welcome Page and a log out link - not
allowing further access to the Welcome Page. Maybe the Login Page could have
a link to the Welcome Page without submitting login/password (just for
testing purpose). I hope I explained my problem well. 

Thanks in advance, 
Edd

[Wicket-user] Serious problem w/ Glassfish V2 Beta 2 & Wicket

[V. Jenks]

I'm attempting to test against the latest Glassfish app server (V2 b41,
a.k.a. Beta 2) and there seems to be an issue with wicket that didn't arise
when I had tested it in earlier versions of Glassfish.  I realize the app
server may be to blame but that may not be entirely true, I'm just trying to
figure out what might be happening...since wicket seems to be the only thing
involved w/ the exception...nothing else in the app is causing any problems.

I built an "enterprise" app in Netbeans 5.5.1, using Java EE 5 as the target
platform and Glassfish V2 Beta 2 as the app server.  I'm trying to (once
again) move our storefront application to Glassfish, which was built using
Wicket 1.2.x and JPA/EJB3.  On my local dev box, everything seems to work as
expected.  I can build, deploy, and run the app.  On the staging box I've
installed Glassfish exactly like I did locally and can deploy the
application, and it runs.  However, if I restart the app server, when the
app comes back up I'm unable to pull it up, I get the following exception:

Re: [Wicket-user] Serious problem w/ Glassfish V2 Beta 2 & Wicket

[V. Jenks]

Thanks for the insight Igor, very interesting, and it makes sense.

However, it doesn't make sense. :P  This has never happened to this
application running on JBoss 4.0.x in over a yearand never happened when
I tested it against Glassfish V1.

Any idea what might be causing this?

Both the source code and version of Wicket I'm using remains unchanged in
the entire time it has been in production...so I'm very skeptical that this
is anything *other* than an issue w/ Glassfish.

I've actually been unable to reproduce the error in the last hour,
vigorously testing by restarting the app server AND undeploying,
redeploying, etc. the application.  This makes me even more nervous. :S

Re: [Wicket-user] Problem with concurren ajax requests on page

[Alex Objelean]

I managed to migrate my application to wicket-1.3 ... but the same problem
still persist...:( -> this time it is complaining that  he is unable to find
the componentRelativePath of the component which is supposed to be added to
the target. :( 


The problem with NPE in DefaultRequestTargetResolverStrategy:295 seems to be
the way wicket retrieves the component using its relative component path... 
[code]
page.get(pageRelativeComponentPath);
[code]
The component which cause the problem was removed and then added back by the
AjaxTabbedPanel before the exception is thrown. 

PS: Btw, when the stable wicket-1.3 version is planned to be released?

Regards,
Alex.

[Wicket-user] Template Pages and Wicket: Best Way?

[Fábio Bombonato]

Hi Everyone,

Well, I´m a newbie in Wicket framework and had some difficulty to figure out
how is the best way to make a template page where all areas defined in this
template could be changed for Pages that use it. I read many topics about
"template", "layout" in mail-list, some examples in Wicket Wiki e some
others of Panels/Borders (
http://www.wicket-wiki.org.uk/wiki/index.php/Panels_and_borders) and the
correct way isn´t clearly for me.

Somebody has any suggestion or example to do this:

For example, if a have a main Template page that define some containers,
like header1, header2, content1:


Template.html:

   
   
   
   
   
   

   
   
   

   
   
   

   
   
   

   
   
   

   
   
   

   
   
   
   




And Pages that use this template and change the contents of this
containers, like:

MainPage.html

   
   
   
   
   
   

   
   
   

   
   
   

   
   
   
   
   

   
   
   

   
   
   

   
   
   
   
   



And other Page, using the same Template but change the content, like:


SignInPage.html:

   
   
   
   
   
   

   

   

   
   
   

   
   
   

   
   
   

   
   
   

   
   
   
   


Thanks for any help!

Yes, here the additional divs  are not wicket components, so wicket
don't change theirs ids (in spite of wicket could repeat them) and I
can apply stylesheet on it but it adds a level in markup, I don't
really like it but it works. (Xavier already suggests it :) )
Thanks

Yes, div could already have a class attribute, e.g. the same for each
ViewPanel, and class could be not used to reference one of them.
But I don't have a pretty solution. Wicket guarantees each component
have a unique id, I understand igor's position.
The best way, I think, is encapsulate a dynamic component in a static
one as Xavier said.

Re: [Wicket-user] session authentication

[eddmosphere]

Thanks for the reply, Marc

I've seen the examples, but didn't understand what were the basic steps to
take..I'm confused whether to use wicket auth-roles, annotations,
SignInPanel, SignInPage, etc etc.. :/

I'll take a better look ate the examples ;)


Thanks again,

Re: [Wicket-user] session authentication

[Marc-Andre Houle]

You can also download the source code of the examples to make some
modification to see exactly what is happening...

There not that much, I'm sure you'll get it...

if you know the place where it does goes wrong now and then

Thanks for the insight Igor, very interesting, and it makes sense.

However, it doesn't make sense. :P  This has never happened to this
application running on JBoss 4.0.x in over a yearand never happened
when
I tested it against Glassfish V1.

Any idea what might be causing this?

Both the source code and version of Wicket I'm using remains unchanged in
the entire time it has been in production...so I'm very skeptical that
this
is anything *other* than an issue w/ Glassfish.

I've actually been unable to reproduce the error in the last hour,
vigorously testing by restarting the app server AND undeploying,
redeploying, etc. the application.  This makes me even more nervous. :S

Re: [Wicket-user] AbortWithWebErrorCodeException not working as expected

[Lowell Kirsh]

The solution you posted there looks workable. Instead of throwing an
AbortException, I'd just call
RequestCycle.get().setRequestTarget(...). However, it seems that to
prevent the rest of my constructor from running (due to the error), I
have to explicitly call 'return' (ie. can't use exception to get out
of constructor). Is there any way I could exit without calling
'return'?

Ok, if that wasn't clear, what I'd like to do is to have a method
requireParameter(PageParams pp, String paramName) in my BasePage, so
that if the paramName value is missing, the constructor would exit
immediately with a redirect or error page. Using exceptions, I'd be
able to simply call:

  requireParameter(...)

and it could throw an exception which would take care of the control
flow of the program. But instead, what I seem to be doing now is:

  if (isMissingParameter(params, paramName))  return;

which is more verbose, but definitely not hideous.

Re: [Wicket-user] Template Pages and Wicket: Best Way?

[Scott Swank]

One way would be to create an abstract page

public abstract class Template extends WebPage
{
  public Template()
  {
add(createHeader1());
add(createContent3());
etc.
  }

  protected abstract Panel createHeader1();
  protected abstract Panel createContent3();
  etc.
}

public class WhateverPage extends Template
{
  protected Panel createContent3()
  {
return new SomeContentPanel();
  }
  etc.
}

[Wicket-user] have problems with AjaxSelfUpdatingTimerBehavior and AjaxTabbedPanel

[Murat Yücel]

Hi All

I had some problem with ajax when using wicket 1.2.6. I read the thread with
the following subject:
Problem with concurren ajax requests on page

Matej suggested that a upgrade to wicket 1.3 would solve the ajax problem.
So i upgraded the application
to wicket-1.3.0-incubating-SNAPSHOT.

Now I have problems with AjaxSelfUpdatingTimerBehavior when using it
together with AjaxTabbedPanel.

Panel 1 includes a subpanel which has an AjaxSelfUpdatingTimerBehavior.
Panel 2 has another subpanel and it doesnt include the subpanel from panel
1.

When swithing "page" from panel 1 to panel 2 then after 5 seconds which is
the duration of the first subpanel
then i get the following error:

org.apache.wicket.WicketRuntimeException: component
contentpanel:menu:panel:showthreads not found on page
dk.team.ninan.web.wicket.BasePage[id = 1], listener interface =
[RequestListenerInterface name=IBehaviorListener, method=public abstract
void org.apache.wicket.behavior.IBehaviorListener.onRequest()]
   at
org.apache.wicket.request.AbstractRequestCycleProcessor.resolveListenerInterfaceTarget
(AbstractRequestCycleProcessor.java:394)
   at
org.apache.wicket.request.AbstractRequestCycleProcessor.resolveRenderedPage(
AbstractRequestCycleProcessor.java:440)
   at org.apache.wicket.protocol.http.WebRequestCycleProcessor.resolve(
WebRequestCycleProcessor.java:137)

The error message is correct because the panel showthreads is no longer a
part of BasePage, but why doesnt the behaviour disappear
when replacing panels? What am i doing wrong? :)

Re: [Wicket-user] have problems with AjaxSelfUpdatingTimerBehavior and AjaxTabbedPanel

[James McLaughlin]

Hi Murat,
I posted a hack to fix this several months back:

http://www.nabble.com/AjaxTimer-clearTimeout-tf3364438.html#a9360559

Essentially, I have the timer check if the markup for the component it was
bound to is still in the page, and return without firing if it is not. Hope
this helps.

best,
jim

Re: [Wicket-user] Serious problem w/ Glassfish V2 Beta 2 & Wicket

[V. Jenks]

It's cool, I got someone on the Glassfish forums to confirm that it's most
likely an issue w/ the app server.  I fell back to a prior version and the
problem has disappeared completely.

Thanks for the help, guys!

Re: [Wicket-user] AbortWithWebErrorCodeException not working as expected

[Eelco Hillenius]

It was a bug we didn't support it properly, and in trunk it's fixed
now (note that the issue is set to 'resolved'). So put in that
exception again, and you should be good.

Thanks for your attention to this. Is there a roadmap of when 1.2.7

Re: [Wicket-user] AbortWithWebErrorCodeException not working as expected

[Eelco Hillenius]

1.3.x is the next version, and this is in trunk. I've only fixed it
for that. If you really need it for 1.2.7, please re-open the issue
and state that and selected 1.2.7 in the list.

There's no roadmap for 1.2.7. It depends on severity of the bugs we
fix for it and how badly people (tell us they) need it. But we're
advising people to upgrade to 1.3.x if they can.

In your case, if you're working on 1.2.x, the workaround is to create
your own AbortWithWebErrorCodeException implementation, but now let it
extend AbstractRestartResponseException (like the fix did). Nothing
wrong with doing that, and it should work without having to upgrade.

[Wicket-user] WicketFilter doesn't work in Weblogic [Wicket 1.3]

[dukejansen]

I believe I have identified a rather serious bug in WicketFilter.

I'm using a recent 1.3 snapshot, and I have recently updated our application
to leverage the WicketFilter instead of WicketServlet. This is working great
in Tomcat, but when we deploy to our Weblogic server, Wicket dies an ugly
death.

After a lot of debugging in both Weblogic and Tomcat, I was able to track
down the source of the problem.

The problematic method is WicketFilter.getRelativePath.

The method uses request.getServletPath to return the relative path. This
works in Tomcat, because Tomcat is nice enough to return the the relative
request URL when you call request.getServletPath, even if it is not
technically mapped as a servlet in web.xml.

But Weblogic is more strict, and so because the URL is not technically a
real servlet, it just returns "".

This causes the Wicket code to think the URL is for the root path, and so it
tries to append the relative path to the registered home page. Since the
method always returns "", Wicket does this forever, continuing to append the
home page path, redirect, then get confused, again and again.

Wanted to post a message to warn others and to find out if anyone was
already aware of this.

I was able to code up a workaround, since the method was public, copying
most of the original logic into my overridden method. But it got a bit hacky
since I didn't have access to private members of WicketFilter.

Essentially, I replaced the malfunctioning first line:

String path = request.getServletPath();

With something that seems to work better:

String contextPath =
StringUtils.nullToEmpty(request.getContextPath());
String path = request.getRequestURI();
if (path.startsWith(contextPath)) {
path = path.substring(contextPath.length());
}

Re: [Wicket-user] getVariation and extended panels

[Joshua Lim]

Ok I'll try...

I was experimenting with the following with 2 panels... bascially
ChildPanel.getVariation() will override the SuperPanel.getVariation() so I
cannot have say a "Blue" SuperPanel" and a "Red" ChildPanel... which would
then make it possible to have flexible combination of layouts by extending
the panels...

I am not sure if this is the right approach, so would like some advice.
right now I have move to just sticking to 1 variation to 1 hierachy

thanks
Joshua


// SuperPanel //

// SuperPanel.Html

   
   
   This is Super Panel
   
   
   

// SuperPanel_Red.html

   
   
   This is Red Super Panel
   
   
   

// SuperPanel.java

public class SuperPanel extends Panel
{
   public String getVariation()
   {
   return "Red";
   }
}

// ChildPanel //

// ChildPanel.html

   
   
   This is Child Panel
   
   

// ChildPanel_Blue.html

   
   
   This is Blue Child Panel
   
   

// ChildPanel.java

public class ChildPanel extends SuperPanel
{
   public String getVariation()
   {
   return "Blue";
   }
}

Re: [Wicket-user] WicketFilter doesn't work in Weblogic [Wicket 1.3]

[dukejansen]

Probably would be wise to look at all calls to
HttpServletRequest.getServletPath.

Re: [Wicket-user] RedirectPage and expiration

[Carlos Pita]

Hi Eelco,

up to date 1.3 snapshots from the maven repo.

The links are inside ListViews that are themselves inside a
TabbedPanel, although I don't think this is related.

I could try to isolate the problem into a minimal page and post it.

Cheers,
Carlos

[Wicket-user] inspecting model from IComponentInstantiationListener

[Ryan Sonnek]

What exactly should a component instantiation listener be able to do?
I'm trying to build one that will inspect the model of every
component, but the model is not yet bound.  is there a way to register
a listener that is notified once the model is bound?

[Wicket-user] POST form submissions being converted to GETs

[Lowell Kirsh]

I have a wicket form which is supposed to be POSTing its data. Looking
at the generated page, it is indeed method="post". But the page that
it redirects to thinks that it is a GET. I found this information by
doing:

WebRequest request = (WebRequest) RequestCycle.get().getRequest();
String method = request.getHttpServletRequest().getMethod();

In this case, method is "GET". I don't get why this is not "POST". So
right now I'm not sure if it's mistakenly thinking it's a GET when it
is indeed a POST, or if it's really a GET. Does anyone have any
recommendation on how I can figure this out (eg. some tool not
associated with wicket)?

Thanks,
Lowell
