Re: JFreeChart with clickable imagemap

[Peter Karich]

Hi James,

In the constructImageMap you whill have to pass a model as well, but I'm
not sure how :-(

Another way would be to adapt constructImageMap to updateImageMap
so that you can call it in ChartImage.createBufferedImage (or every time
the model updates)

BTW: For jetwick I used an html solution with div's to display bar charts.
which is customizable by the designer (if any ;-)), readable by spiders etc
and didn't need those imagemaps. Are you interested in this solution? I
could blog about it.

Regards,
Peter (aka timetabling on twitter ;-)).

Modal window and Ajax exception

[Altuğ Bilgin Altıntaş]

 Hi;

I have Webmarkupcontainer which includes ListView and I am using jquery
Table Sorter.

When i open a update modal window and close model window and refresh table
via Ajax i got :

Wicket.Ajax.Call.processEvaluation: Exception evaluating javascript:
[object Error]
*INFO: *Response processed successfully.

And all jqıery table sorter's features gone

My wicket version : 1.4.9

I've read https://issues.apache.org/jira/browse/WICKET-2663 but it says it
is fixed since 1.4.7

Any idea ?

Thanks.

continueToOriginalDestination not working correctly

[Pepijn de Geus]

Hi all,

I'm working on a website were the customer can enable a splash page that will 
be displayed once per session to every visitor entering the site.
To achieve this, I've added a small session check with a to my BasePage, which 
is the parent of all webpages:

if (!getSession().isSplashShown()) {
SplashData splash = em.find(SplashData.class, SplashData.ID);
if (splash.isEnabled()) {
throw new RestartResponseAtInterceptPageException(SplashWebPage.class);
} else {
getSession().setSplashShown();
}
}

This works like expected; the user is redirected to the URL the SplashWebPage 
is mounted on.
On the SplashWebPage, which does not extends BasePage, I've added a 
AjaxFallbackLink like this:

session.setSplashShown();



add(new AjaxFallbackLink("close") {
private static final long serialVersionUID = 1L;

public void onClick(AjaxRequestTarget target) {
if (!continueToOriginalDestination()) {
setResponsePage(HomePage.class);
}
}
});

Clicking this links does not work. The log tells me:

"ClassName=org.apache.wicket.protocol.http.WebResponse;MethodName=redirect;|Redirecting
 to "
(nothing after 'to', only a space)

and the AJAX response reads:



I was able to solve this issue by either:
- Changing the link to a non-ajax one
- Mounting the SplashWebPage on a path 'deeper' then the one the user 
originally tried te open, such as "/splash/work/please". The user is then 
redirected to "../../" correctly.

It this a bug in Wicket, or am I doing something stupid?

Thanks in advance,
Pepijn

Understanding wicket lifecycle and model past to wicket components

[Brown, Berlin [GCG-PFS]]

I have two scenarios, a and b.  In one case I use the loadable
detachable model and the other I don't.  Is it possible when the wicket
component in scenario b is deserialized, is it possible that the object
won't be available?
 
 
 
(a) Page Constructor code with Loadable detachable model:
 
MyPage.java:
...
final Form form = new Form(FORM, new
CompoundPropertyModel(new LoadableDetachableModel() {
  
   @Override
   protected AppBean load() {
final AppBean AppApplication = (AppBean)
WicketSession.get().getApp();  
return AppApplication;
   }   
  };
});
 
---
 
(b) Page Constructor without Loadable detachable model:
 
MyPage.java
...
LINE2: final Form form = new Form(FORM, new
CompoundPropertyModel((AppBean) WicketSession.get().getApp())
<--- offending call
 

---
 

SomeOtherPage.java:
public SomeOtherPage() { 
  new Link() {
onClick() { 
  setResponsePage(MyPage.class);  < Use wicket deserialization
to get MyPage.class, constructor not called.
 }
   }
}
 
LINE2: (AppBean) WicketSession.get().getApp()
 
QUESTION: in scenario (B), is it possible that the call to create the
Form will be null? if I don't use the loadable detachable model?
Because the constructor was not called to render that page again.

Coding - On Software Design Process

[Jonathan Locke]

Hello Wicketeers!

I recently finished writing a short book (less than 70 pages) on software 
design process. I wrote this book because I wanted a place to put down some of 
the most interesting ideas and things I've learned about software design over 
the years that have been too long for everyday conversations and emails. If you 
have worked with me or are familiar with my work through Wicket, you will find 
a lot of things that feel familiar in this book and it may shed some light on 
some aspects of Wicket's design for you. It's also my hope that it will help 
people who read it carefully to improve their software design process. You can 
get it for Kindle using the link below (or better yet, get your pointy-haired 
boss to get it for you) or if you prefer dead trees, there will be a paperback 
available on Amazon in a few days. As I say in the introduction, this book is a 
conversation starter, so I'd be very interested to hear thoughts and reactions 
from readers. Enjoy!

http://www.amazon.com/Coding-Software-Design-Process-ebook/dp/B0042X99SA

Best,

 Jon

IDataProvider advice needed – caching?

[Troy Cauble]

I need an IDataProvider for web services calls to a Flickr search.

To complicate matters, I need to cull the Flickr results based on
local criteria.  So the Nth item to the user is the N + Mth item from Flickr.
And I can't know M without looking at the all the Flickr results up to
N + M.

So to handle a user paging back and forth, I either need to
a)  cache the Flickr data (tuples, not images)
b)  cache a mapping from the user index to the Flickr index
c)  start from 0 with flickr and count up each time the Provider is used.

Even with a cache (a & b), I'll have to fetch the data in between if
a user jumps from page 1 to page 5.

So my questions are

1)  How much data is it reasonable to let an IDataProvider serialize?
 2000 short strings?  4000?  Or how large of a TreeMap?
2)  If I wanted to cache outside the IDataProvider serialization (global
 mem or another process), there's no way to know when a user is
 done with the cache, right?  (When they close that window or tab?)
3)  Have I missed any approaches?  Something besides IDataProvider?
 Anything?

Thanks,
-troy

Re: How to use jWicket ResizableBehavior

[Sebastian]

Looks like there is a problem in the ResizableBehaviour class. It does 
not ensure that the necessary jQuery CSS is added to the markup. Since 
the method that could do this has protected visibility I need to 
subclass the ResizableBehaviour like this:


ResizableBehaviour resizer = new ResizableBehaviour(){{ 
addUserProvidedResourceReferences(AbstractJqueryUiEmbeddedBehaviour.jQueryUiBaseCss); 
}};

myComponent.add(resizer);

Hi,

I'd like to make a DIV resizable. The JavaDoc of ResizableBehavior says
I just need to add a new behavior instance to a Wicket component (in my
case a WebMarkupContainer) to make it resizable. Doing so results in my
HTML output referencing the minified jquery libs and containing code
like "jQuery('mydiv#2').resizable(...)". However the DIV did not change
at all and it is not resizable. What do I miss?

Forms ajax doesn't update components models

[Tito]

Hello,

I'm doing a form that adds textfields when I choose an option in a ComboBox.
When Combo changes one panel become visible and other invisible.
The problem is when that panel appears and I click submit button the model
of it does't update.
I have seen that browser submit the info, but wicket doesn't process it. I
don't know if i'm doing anything wrong or is a known problem.

Thank you.
Excuse me for my bad English. I'm from Argentina.

I'd think that this kind of logic and caching should be put into your
service layer.  Depending on your application, it is very likely that the
cached data could be used for multiple users.  Besides, your UI should just
be able to call into the service layer and not worry about these details.

At the service layer, you can use something like memcached and set the
timeout appropriately for your session length / usage combo.

Wicket Rich Text Editor with YUI 2

[Jered Myers]

 We are looking for someone to make a Rich Text Editor using Wicket and 
YUI 2.  We are looking to make the editor easy to work with on the Java 
side (e.g. simple configuration of the toolbar via Java).  Its basic 
implementation if very javascript heavy and we want to be able to 
manipulate the control in a "Wicket" manner (e.g. see DatePicker), so 
that it can be used as easily as Wicket's TextArea.  The job, with the 
full details, is posted on RentACoder at 
http://www.vworker.com/RentACoder/misc/BidRequests/ShowBidRequest.asp?lngBidRequestId=1507539.

Re: Wicket Push for Java 5?

[Rodolfo Hansen]

Regarding this patch..

Michael: how would you deal with a mixed jdk version project?

should we move push-parent to jdk1.5 and disable the
animal-sniffer-maven-plugin for the cometd module?

RE: continueToOriginalDestination not working correctly

[Chris Colman]

I had a problem using continueToOriginalDestination with very similar
symptoms that was only a problem for IE? Does yours affect all browsers
or just IE? My problem only occurred in IE and only if the redirection
was to the root of the app, redirecting to any folder *under* the root
worked fine - very similar to what you state.

At the time I raised issue:

https://issues.apache.org/jira/browse/WICKET-2912

but it has since been marked as 'cannot reproduce' so I thought it must
have been some querky issue with my particular app.

I'm not sure if this is the same as your problem but I fixed the problem
in my environment by making a change to the wicket source code
(org.apache.wicket.PageMap:continueToOriginalDestination() which I have
outlined in a comment in the above JIRA page. It basically involves an
extra test of the interceptionContinuationURL and then a subsequent
stripping of the any leading '/'.

From:

// If there's a place to go to
if (interceptContinuationURL != null)
{
...
}

to this:


// If there's a place to go to
if (interceptContinuationURL != null)
{
if ( interceptContinuationURL.length() > 0 &&
interceptContinuationURL.charAt(0) == '/' )
interceptContinuationURL =
interceptContinuationURL.substring(1);  

...
}

And now it works fine on IE as well.

wicket-auth-roles and SSO

Hi,

Our application relies on Wicket-auth-roles, Spring Security 3 and SSO
(SiteMinder); The login page (login mechanism) is outside of the
application. Our WebApplication must extend AuthenticatedWebapplication and
thus implement getSignInPageClass(); What should we return ?

Re: Bug in Wicket Push TimerChannelService when used with background threads

[Rodolfo Hansen]

Hi Sebastian, your patch is in: 

trunk (1.5)
1.4 branch (future 1.4.13 release)
and 1.4.12

There was an issue in your patch where the application could be left in
the ThreadContext, which was fixed, 
as well as a simplification in the trigger function.

Re: Bug in Wicket Push TimerChannelService when used with background threads

[Sebastian]

> There was an issue in your patch where the application could be left

Hi Rodolfo,

I think you are referring to

try {
  Application.set(_application);
  methods[m].invoke(o, parameters);
} finally {
  Application.set(originalApplication);
  if (originalApplication != null) Application.set(originalApplication);
}

The problem is if this code is executed in a separate thread the 
originalApplication will be null. If you just omit the null check in the 
finally clause the setter will throw an IllegalArgumentException. So to 
remove the app from the ThreadContext we would have to call 
Application.unset() instead:


if (originalApplication == null) Application.unset();
else Application.set(originalApplication);

Regards,
Seb

Problem Deploying Wicket/JPA (EclipseLink) App to Glassfish

[Shelli Orton]

Hi,

 

I have a small Wicket app that I can deploy to Glassfish v3 without any
problems.  I also have a JAX-RS webservice that includes a jar file that
contains JPA entity beans and stateless service beans that deploys
successfully.  However, when I try to deploy a different Wicket
application that makes use of the same entity/service jar, I get this
exception:

 

SEVERE: Exception while invoking class
org.glassfish.ejb.startup.EjbDeployer load method

java.lang.RuntimeException: Unable to load EJB module.
DeploymentContext does not contain any EJB  Check archive to ensure
correct packaging for C:\Program
Files\glassfishv3\glassfish\domains\domain1\applications\MyApp

  at
org.glassfish.ejb.startup.EjbDeployer.load(EjbDeployer.java:133)

  at org.glassfish.ejb.startup.EjbDeployer.load(EjbDeployer.java:63)

  at
org.glassfish.internal.data.ModuleInfo.load(ModuleInfo.java:175)



 

The same dependent jar files are included in both the Wicket and web
service wars.

 

Does anyone know if this a Wicket/JPA/Glassfish issue or something else?

 

Thanks!

 

Shelli

Printing an inmethod grid

[Adz]

Hi,

I'm using an inmethod grid which is working great for me, but when I try to
print I only get the data that is on the screen.  I get all the headers,
including the ones off screen, but not all the data, anyone have a
fix/workaround for this?  I'm thinking maybe a print.css that overrides the
standard styles defined in inmethod?

cheers,

Adam

Programmatically change an HTML attribute value.

[Ichiro Furusato]

Hi,

I'm assuming this is a dumb question but I wasn't able to locate an answer
for what must be an extremely common need. I found the docs on "How to
modify an attribute on a HTML tag" but that doesn't quite fit, as the examples
are all for elements that are themselves created programmatically. Mine is
solely in markup.

I've got a lot of HTML markup surrounded by a  element. The 
element isn't created via Wicket, it's in my HTML file. It has a fair bit of
descendent content so I don't want to have to create that via Java, as
I'm assuming if I put a wicket:id on the  element that would replace
everything within the . I just want to programmatically alter its 'class'
attribute, but I don't see how this is accomplished.

E.g.,



... etc.



This would effectively be some kind of query to locate the  element,
then a modification of its 'class' attribute.

Alternately, if I am required to create the  element programmatically,
how I attach a whole lot of HTML markup to it? Do I have to use a fragment?
That seems like a lot of work to just alter an attribute value, so like I said,
I must be missing something obvious here...

Re: Wicket Push for Java 5?

[Michael O'Cleirigh]

 Hi Rodolfo,

I think you would need two wicketstuff-push parents (one for java5 and 
one for java6) each with a separate artifactid.


Like:

wicketstuff-core -> jdk-1.5-parent -> push-parent-jdk-1.5 -> containing 
all but the cometd artifact
wicketstuff-core -> jdk-1.6-parent -> push-parent-jdk-1.6 -> containing 
the comentd artifact.


If there is a dependency from the cometd artifact to the java 5 push 
artifacts it can be resolved by building the java 5 artifacts first 
(both in hudson and when the release is cut).


Regards,

Mike




Regarding this patch..

Michael: how would you deal with a mixed jdk version project?

should we move push-parent to jdk1.5 and disable the
animal-sniffer-maven-plugin for the cometd module?

If you send a patch separating the cometd out, so the rest of push can

Hi,

why is the wicket push module available in the Maven repo1 compiled
with Java 6? I checked out the code and cannot find a single usage of
any new Java 6 features (except the @Override annotation used on
methods of implemented interfaces).

I'm currently working in an environment where only Java 5 is allowed.
all other wicket components retrieved via Maven repo1 work fine here.

Re: JFreeChart with clickable imagemap

[James]

Hi Peter,

Thanks for your prompt reply.
I don't know how I missed this wonderful mailing list for this long.. ;-(

I have tried passing models to constructImageMap (wrapping the chart image
object as a model) but somehow the map was not updated.

I checked jetwick and it looks cool. ;-)
Do you use JFreeChart to create those charts?
I'm willing to try that option as well. Kindly blog about it!

Thanks once again for taking your time to reply.

Re: Programmatically change an HTML attribute value.

[James]

Hi Ichiro,

This is what I use in a ListView to change the "style" attribute of table
rows to give alternate colours to them.


item.add(new AttributeModifier("class", true, new
AbstractReadOnlyModel()
{
@Override
public String getObject()
{
return (item.getIndex() % 2 == 1) ? "even" : "odd";
}
}));


I think you can add attributes like this to any component.

Re: Programmatically change an HTML attribute value.

[Michael O'Cleirigh]

 How about using a WebMarkupContainer?

Then you can use an attribute modifier like the below example to set the 
class value.


All you have to do is make the new component heirarchy match the markup 
heirarchy.




("even")));

add (c);

c.add (new Form("form"));

Another option might be to use a border to add the wrapping  and 
class attribute.

Mike

Safari and AjaxEditableMultiLineLabel incompatibility?

[Arturo Perez]

Using wicket 1.4.10 and Safari 5.0.1.

I'm using the AjaxEditableLabel in a ModalWindow no problem.  But the 
AjaxEditableMultiLineLabel doesn't go editable when it's clicked. I 
checked under FireFox 3.6.10 and it works there.

Is there a known incompatibility?  Is there a known fix, if so?

Re: Programmatically change an HTML attribute value.

[Ichiro Furusato]

Hmm. Thanks for the answers guys but from what I've understand
so far from my own digging and your answers is that the container
 I want to modify still needs to be created programmatically,
and I'm distinctly trying to modify the attribute of one that begins its
life in markup (i.e., in the .html file, not the .java file).

It seems that may not be possible in Wicket so I'll probably have to
push the contained markup into a fragment and add it to a
programmatically-created element. Not quite what I wanted (and
more complicated than I'd prefer) but doable.

It's a shame something that can be accomplished with a simple
DOM manipulation (get element by ID, then set its attribute value)
ends up being fairly complicated.

Thanks!

Re: Programmatically change an HTML attribute value.

[Ichiro Furusato]

Ack, sorry, I managed to figure it out via Michael's suggestion.
Here's the result. This show the relevant parts of embedding a
userpanel into a templatepage:

TemplatePage.html:


   user


TemplatePage.java:

WebMarkupContainer c = new WebMarkupContainer("userdiv");
c.add(new AttributeModifier("class",true,new Model("even")));
add(c);
c.add(new UserPanel("user"));   

The resulting markup:


   
   ...
   


and I'm able to programmatically alter the value of the
'class' attribute on the userdiv (wrapper div) element.
It was a bit more complicated than I'd wished, but not
onerously so, and frankly not much more code than
using the DOM.

Thanks very much guys!

Ichiro

Re: alphabetical paging navigator

[Igor Vaynberg]

it wouldnt be worth overriding one, you are better off creating one
from scratch.

listview and paging navigator are decoupled, so you can use your own
impl to page the listview without problems.

Re: JFreeChart with clickable imagemap

[James]

Guys,

Finally managed to display the tooltip generated by JFreeChart in the wicket
page by following these
instructions
.
Had only an example markup been given in that post, it would have saved lots
of frustrating hours I spent. :-(

For anyone looking forward for showing the tooltips in a chart generated by
JFreeChart, here is the markup you might need.





For the java part, use this
code
.

Your output should look something like this..


   
   

   



NOTE:

  - You must use  
 and not   
  - You must use the "#" symbol before the "usemap" id.
  - The image map related html markup is generated by the api provided by
JFreeChart.

Wicket 1.5 and OSGi

[Eike Kettner]

Hello!

I developed a wicket app using OSGi (felix) where different bundles may
contribute content to the wicket bundle. It works really nice using
wicket 1.4.9+. Now I want to upgrade to wicket 1.5 and I run in problems
starting the osgi container.

It complains with the good-known classnotfound-exception for classes
like IClusterable and AuthenticatedWebapplication which all are classes
in packages exported by more than one bundle (for example
org.apache.wicket or org.apache.wicket.authentication). Earlier I found
this was a problem or at least a "not-good" for OSGi bundles. But as am
using OSGi 4.2 this may work with some special treatment (I'v never
tried this though). Do you think I'm doing something wrong or is this
something on the road for 1.5?

Also, since I have implemented ..UrlCodingStrategy and a custom
RequestTarget I'm studying the new request handling in 1.5 sources to
find out where to "plugin" my stuff. Are there any documentation besides
source and javadoc for the new concepts? The code is good to read but if
there are some pictures and text available it would be of great help.

Thanks in advance!
Eike
