Re: [NEWBIE] How to do if... else... switch... in wicket html ?

2009-03-17 Thread Sébastien Piller

Hi,

Use panels, and instantiate either one type or another on the java side. 
Then your content will change.


Cheers,

Hi,

What is the best technique to do some if else and so on with wicket ?

I need a html with something like that (stupid and naïve approch) :

wicket:if (something = toto)
 div do this thing/div
wicket:else if (something = foo)
 pa href=error.htmlIt's not good/a/p
wicket:else if (something = other)
 divrender other/div

How to do that with wicket ?

Thanks.

Dear wicket users and wizzards!

Is ist possible to use wicket to implement partial pages that can be
embedded into another page? E.g. to have a normal content management
system like Joomla and use wicket top lug it into exisiting pages for
some dynamic, database driven content? The HTML that is created by
wicket must not contain the usual htmlhead... part.

Any Ideas hints?

Re: Wicket placeholder for tr component causing invalid markup

2009-01-26 Thread Sébastien Piller

Hi,

I'm pretty sure what you need is wicket:enclosure [1] instead

[1] http://cwiki.apache.org/WICKET/wickets-xhtml-tags.html


the_adam wrote:

If we have a component with a corresponding markup tag tr and want to hide
it and display placeholder tag via Component#setOutputMarkupPlaceholderTag
the resulting markup will be:

tr style=display: none; id=componentId/

However this is not a valid markup. The proper markup would be:

tr style=display: none; id=componentIdtd span=x/tr where x is
the number of columns. Obviously wicket won't know how many columns there
are so one would have to set that explicitly.

Are you planning to anyhow address this issue, i.e. provide a different
placeholder method (maybe
WebMarkupContainer#setOutputRowPlaceholderTag(boolean, short)) or is the
only way of solving this to manually swap component-to-display with custom
placeholder component?

Re: access ServletOutputStream in wicket

2009-01-16 Thread Sébastien Piller
I really doubt that such an exception may be fixed by upgrading 
jasperreport (NotSerializableException is pure wicket exception, not a 
jasper one).


The stacktrace shows you that the problem is here:

   final java.io.InputStream
com.homeaccount.web.jasper.JRResource$1.val$report
[class=java.io.ByteArrayInputStream] - field that is not serializable


so nothing to do with jasperreport. Just declare your streams as 
transient
and lazy-init it in an initialisation method. And don't forget to close 
them as well...


I you want to, here is how I've my generation of pdf:

# Part that generate a PDF to a byte array

   public byte[] create(int orderid) {

   final JasperReport report;

   Order o = getOrder(orderid);

   try {

   report = (JasperReport) JRLoader.loadObject(InvoiceCreator.class

   .getResourceAsStream(

   /jasperreports/Invoice/Invoice.jasper));

   } catch (JRException e) {

   throw new RuntimeException(e);

   }

   final Map params = new HashMap();

   params.put(basedir, /jasperreports/Invoice/);

   params.put(curr, o.getCurrency());

   params.put(orderid, o.getId());

   params.put(shopid, o.getShops().getId()); 


   params.put(REPORT_LOCALE, new Locale(fr);

   byte[] bytes;

   DataSource dataSource = Globals.getDataSource();

   Connection connection = DataSourceUtils.getConnection(dataSource);

   try {

   bytes = JasperRunManager.runReportToPdf(report, params,

   connection);

   } catch (Exception e) {

   bytes = null;

   throw new RuntimeException(e);

   } finally {

   DataSourceUtils.releaseConnection(connection, dataSource);

   }

   return bytes;

   }


# Part that write that data to the wicket's stream

   private static Link newInvoiceLink(String string, final Integer id) {

   return new Link(string) {

   @Override

   public void onClick() {

   getRequestCycle().setRequestTarget(new 
ResourceStreamRequestTarget(new AbstractResourceStream() {

   private static final long serialVersionUID = 1L;

   private transient InputStream is = null;

   public void close() throws IOException {

   if (is != null) {

   is.close();

   }

   is = null;

   }

   public InputStream getInputStream() {

   if (is == null) {

   is = new ByteArrayInputStream(getInvoice(id));

   }

   return is;

   }

   }, Invoice # + id + .pdf));

   }

   };

   }


This way you won't have any serializableexception anymore.

Hope this help

Tobias Marx wrote:

Hi there!

There are some things in Wicket I am missing and I think they could improve the 
framework a lot.

But just some small background first:

In my opinion the most important things in a web application are:

- as few lines of code as possible, as many as really necessary

- separation of design and web application code and logic

- if a webapplication changes in the design or some small items are added this 
should be possible without needing a java developer


Therefore I would like to suggest more intelligent templates in Wicket:

1. Pass parameters inside of wicket components eg:

div wicket:id=myComponent paramA=blabla paramB=blabla2/div

and make them accessible in the Java code.

This is  a way to customize and reuse components purely by editing templates


2. Make Strings/Labels accessible directly in templatesto avoid redundant 
code like this:

add(new Label(indexTitle, .) and instead allow to add properties directly.

3. Pick up components automatically without needing to add them in the Java 
code:

add(new LastPostsPanel(lastPostsPanel));
add(new NewsPanel(newsPanel));

This could be matched automatically

I think Wicket could be better without so much redundant copypaste code...by 
improving templates

Thanks for listening...

Re: Dynamic PDF Creation

2009-01-09 Thread Sébastien Piller

Some little points:

- on the onsubmit of a form (or any onsubmit like in button, 
submitlink, ajaxfallbackbutton, etc.) you don't need to verify the 
validity: wicket does it for you, it firsts validate the form and then 
call onsubmit if there is no error. Thus it means you can remove your 
validateCriteria and if(!haserrormessage)
- you don't need to implement the whole IRequestTarget interface 
yourself, instead you may use some existant implementation (this 
requires less work for you) for exemple ResourceStreamRequestTarget 
(which is the most usefull in your case). There are dozens 
implementation of IRequestTarget in the framework, just have a look to 
find one which fit your needs.
- this is often dangerous/expensive to add non-static inner classes 
(like you do with your anonymous implementation), because of 
serialisation of pages (reference to your top level class is hold in the 
inner class, and thus gets serialized if the inner instance needs to). 
Be aware of your session size, it is really important under heavy load.

Thanks for the response!  It seems to be working well.  I am posting what I

Re: Prototyping mode: Automatic markup generation

IMO it is not required. This kind of error appears mostly with

anymore after.


For me, the behavior of wicket with that error is quite good. No need 
for some magical generation of markup.


This may lead to wrong use of the framework, too (user may think that 
they don't have to write any markup, and obviously this is not the case)

failed to render. A common problem is that you have added a component 
in code but forgot to reference it in the markup.


Would it not be possible for Wicket to simply ignore the markup aspect 
if so instructed, and generate the required markup on-the-fly from the 
Java tree? Perhaps it's because I am new, but I sure run into that

However, I'm sure that class is in my path... I can see it under
/libs/wicket-extensions-1.3.1.jar. And if I make a clean start (ie stop
tomcat, manually clean the webapps folder, restart tomcat and copy my
file.war), then everything works fine.

Is it a classloader issue or something like that? How to avoid this?

Re: Handle Hibernate transaction in wicket

2008-02-20 Thread Sébastien Piller
Yes, I read a bit about Spring some time ago, but atm I'm working on a 
project that will be released soon. I can't afford to rewrite half my 
code on the lasts weeks ;)


Next time, I'll take some time to getting started with it. I'm sure it's 
worth, that's what I read all the day. But I must consider my 
colleagues, too... They are not very very interested with dev, and 
already have difficulties to write php... so, with Spring, they will 
shot themselves :)


Thx

Re: Problem on undeploy

Hello,

I just tried it, and it worked :) I don't know if I can use this 
directive on my deployment server... I'll have a look with my hoster.


After some investigation, I'm now quite sure that it's a Wicket problem. 
I tried with a very simple project (Hello World) and it made the lock.


Could anybody tell me if it's a known bug or if I have to write a jira?

Thanks

Handle Hibernate transaction in wicket

2008-02-13 Thread Sébastien Piller

Hello,

I'm searching for a best practice to integrate some hibernate 
transaction with Wicket. I'd like to implement the session-per-request 
that is described here 
http://www.hibernate.org/hib_docs/v3/reference/fr/html_single/#tutorial-firstapp-workingpersistence


I think I can commit the transaction and close the session on the 
onAfterRender method. But where is the best place to start it? On the 
first line of the constructor? Or in the onBeforeRender (I think not)? 
Anywhere else?


And what about the ajax queries? I need to recreate a new transaction 
for each ajax request, need I?


Thank you a lot for your think :)

Load resource from anywhere on the HDD

2008-02-11 Thread Sébastien Piller

Hello,

I have a little question: my app lets the user upload some files on the 
server side. I would like to put them somewhere on the server hdd, out 
of the context of the application (let say on /dev/etc/uploads), so when 
I redeploy my war (update of the system), all the uploaded files aren't 
going to be deleted.


I just don't know how to reference them, when they are not in any 
package (this files are images, swf, and other binary, and I need to 
display images  swf in html). I searched for some ResourceReference, 
but none of them lookup out of the webapp.


Need I to write my own ResourceLocator/ResourceReference to achieve 
that? Or is there something existant in wicket?


Thank you vm ;)

AjaxFormValidatingBehavior: getting NotSerializableExc

2008-02-06 Thread Sébastien Piller




Hello guys,

I'm having a little problem with the use of AjaxFormValidatingBehavior.
I add it to all my fields, using a visitor.

 form.visitChildren(FormComponent.class, new IVisitor()
{
 public Object component(Component component) {
 if (component instanceof TextField) {
 component.add(new AjaxFormValidatingBehavior(form,
"onkeyup") {
 private static final long serialVersionUID = 1L;
 
 @Override
 protected void onError(AjaxRequestTarget
target) {
 super.onError(target);
 updateFieldsCssClasses();
 }
 
 @Override
 protected void onSubmit(AjaxRequestTarget
target) {
 super.onSubmit(target);
 updateFieldsCssClasses();
 }
 });
 } else if (component instanceof DropDownChoice ||
component instanceof CheckBox) {
 component.add(new AjaxFormValidatingBehavior(form,
"onclick") {
 private static final long serialVersionUID = 1L;
 
 @Override
 protected void onError(AjaxRequestTarget
target) {
 super.onError(target);
 updateFieldsCssClasses();
 }
 
 @Override
 protected void onSubmit(AjaxRequestTarget
target) {
 super.onSubmit(target);
 updateFieldsCssClasses();
 }
 });
 }
 
 return null;
 }
 });


But when this code is rendered, it throws this exception:
org.apache.wicket.util.io.SerializableChecker$WicketNotSerializableException:
Unable to serialize class: xxx$10
  Field hierarchy is:
   2 [class=xxx, path=2]
  ...
  at java.lang.Thread.run(Unknown Source)
  Caused by: java.io.NotSerializableException: xxx.$10
   at java.io.ObjectOutputStream.writeObject0(Unknown Source)
   at java.io.ObjectOutputStream.defaultWriteFields(Unknown
Source)

However, AjaxFormValidatingBehavior implements Seriablizable... so I
don't understand why Wicket complains about it...

Have I miss something?

PS: it works this way under at least 1.3.0 and 1.3.1

My first guess is that the IVisitor is not serializable. Since you
create two nested anonymous inner classes inside one another, the
behaviors keep a reference to the IVisitor.

DDC and page reload

2008-01-30 Thread Sébastien Piller

Hello,

I have a little problem with drop down choices. I have one on my page. 
It stores some currencies. In the same page, I've got a Flash module, 
who needs the actual currency to work. I pass it using the usual 
flashvars.


But when I change a currency on the DDC (ie from USD to EUR), the actual 
page is refreshed (or seems to), but the currency passed in the 
flashvars is the old one (USD) although all of my models are properly 
updated. So I think wicket hasn't recomputed some markup...


Can I force him to fully reload (recreate) the current page when a 
onSelectionChange event is fired?


Thanks!

Re: DDC and page reload

2008-01-30 Thread Sébastien Piller

Yes, no problem, but it's really trivial...

My Flash object is added here (I use the ShockWaveComponent, little 
modified, from the wiki):
  
   ShockWaveComponent swf = new ShockWaveComponent(swf, 
ShirtDesignerV2.swf, 770, 480);

   swf.setValue(quality, high);
   swf.setValue(bgcolor, #869ca7);
   swf.setValue(id, editor);
   swf.setValue(name, editor);
   ...
   String curr = getCurrentCurrency();
   swf.setValue(flashvars, somevar= + somevalue+ currency= 
+ curr);

   swf.setValue(allowScriptAccess, sameDomain);
   swf.setValue(type, application/x-shockwave-flash);
   add(swf);

And here I change the currency with the DDC:
   DropDownChoice currencies = new 
DropDownChoice(currencies, new PropertyModel(this, currentCurrency), 
Arrays.asList(new String[] { CHF, EUR, USD })) {

   @Override
   protected boolean wantOnSelectionChangedNotifications() {
   return true;
   }
  
   @Override

   protected void onSelectionChanged(Object newSelection) {
   //System.out.println(SETTED:  + newSelection);
   setCurrency(newSelection + );
   }
   };
   add(currencies);

There is nothing special here

But when the onSelectionChanged is fired, the flashvars doesn't change

Thanks ;)

Upload files using Flex (php move_uploaded_file equivalent)

2008-01-22 Thread Sébastien Piller




Hi everybody,

I have a problem with my application. 

I need to upload some files on the server using an Adobe Flex
application. Flex doesn't provide much control for the file upload, I
can't get the raw file data that I want to upload (so I can't send them
in the url, or encode them or anything else). 

On the server side, I have a wicket page, with a constructor taking
only one page parameters argument ("public
MyUploadPage(PageParameters params)")

The only thing that doesn't work is when I need to write the data/move
them with wicket (I receive nothing in the page parameters). I saw some
code in PHP like that:

 $file_temp = $_FILES['file']['tmp_name'];
   $file_name = $_FILES['file']['name'];
  move_uploaded_file(...);


What is the direct equivalent in Wicket?

Thanks!

   return new Roles(new String[] {"poweruser","admin","sysadmin"});
}

If it's possible, what is the right syntax?

PS: I've read a bit about wasp/swarm, but it looks too much complicated
for
my needs (I just need to prevent some components to be instantiated for
some
kinds of users). Hiding/showing links and such fonctionnality is not
needed

Thank you ;)

I answered your first post (where you omitted { and }).

I have seen your correction after sending this

;)

 Yes, I tried it too, but it doesn't work.

The right syntax seems to be @AutorizeInstanciation( *{* "poweruser",
"admin", "sysadmin" *}* )

Thanks

hi
i don't have enough experience in this topic like you but i think if you
look at wicket-role-auth-example it's usuful and
 i think you must wite  this :
@AuthorizeInstanciation("poweruser,admin,sysadmin")
in this way:
@AuthorizeInstanciation("poweruser ", "admin", "sysadmin")

 Hello,

I'm using the wicket-auth-roles package to allow or restrict access to
some
pages. I need to autorize the instanciation of some pages to several
roles.
Is it possible to write something like:

@AuthorizeInstanciation("poweruser,admin,sysadmin")
class Mypage extends WebPage {...}

and something like this in my authenticated session:

public Roles getRoles() {
   return new Roles(new String[] {"poweruser","admin","sysadmin"});
}

If it's possible, what is the right syntax?

Re: HTML code inside language file

Hi

I'm trying to use some HTML codes with internationalized page. For example,
some texts have words in italic and I need to use the i tag. But when
wicket renders the text the i tag is showed on screen instead make the
word italic. Any suggestion?

Thank you
Marco

  

Hi,

just call setEscapeModelStrings(false) on your label ;)
