The proper markup would be: 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.

Re: access ServletOutputStream in wicket
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

Re: Things I miss in Wicket
Hi,
1) and 2) are already implemented, or something very close exists. 3)
may be a good improvement, maybe with a new wicket tag
(). let's see what think
core developpers
1) you have various way of altering tags and attributes:
attributemodifiers, attributeappenders, overriding oncomponenttag,
oncomponenttagbody...
2) you have the special wicket tag "key="resourcekey">[...]" to automatically add labels
and stringmodels without any java representation
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:
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 copy&paste code...by
improving templates
Thanks for listening...

Re: Dynamic PDF Creation
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.

Handle Hibernate transaction in wicket
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 :) - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Load resource from anywhere on the HDD
Sorry, it is solved I'm too stupid, or need glasses...
The only need to fix this problem is to configure the resource finder,
in the init() method of the application class...
WebApplicationPath resourceFinder =
(WebApplicationPath) getResourceSettings().getResourceFinder();
String s = "/etc/path/to/uploads/dir";
if (!new File(s).exists()) {
new File(s).mkdirs();
}
resourceFinder.add(s);
Nothing else to change... reference your resource the same way as
anything else...
Wicket is really pleasant. Every problem has a nice solution ;)

Load resource from anywhere on the HDD
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?

AjaxFormValidatingBehavior: getting NotSerializableExc
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]

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

DojoColorPicker seems not to work
Hello,
I'm using DojoColorPicker (latest trunk from the svn) for the first
time and I think I've found an issue.
I use it very trivialy:
rvbhexcode = new DojoColorPicker("rvbhexcode", new
PropertyModel(formTarget, "rvbhexcode"));
rvbhexcode.setRequired(true);
form.add(rvbhexcode);
In IE6/IE7, it is rendered as a normal textfield (there is no
colorpicker on the right).
Under Firefox, I can select a color, and its hexa code is properly
setted on the textfield. But when I submit the form, the model is not
updated (the selected color is not setted to my model, and the form
cannot submit, it complains about a required field not filled).
Is it a known issue? Or do I something wrong?
Does another color picker exist in wicket?
Thank you ;)

Re: DDC and page reload

this:

Re: DDC and page reload
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"+ "¤cy="
+ 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 ;)

DDC and page reload
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?

Upload files using Flex (php move_uploaded_file equivalent)
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!

Re: @AuthorizeInstanciation and several roles
Well, with swarm I do need to define the policy files, which isn't
trivial for me (I never saw this kind of syntax before).
And there is a lot of new classes/interfaces in this api (SwarmWebApp,
Principal, SwarmActionFactory, LoginContext, ...) with no much
documentation. It's not easy to transform an AuthenticatedWebApp in a
SwarmWebApp.
I think wicket-auth-roles is more clear and easy to use (just to put an
annotation and implement getRoles in the session). It's trivial and
looks pretty. When I need to, I manually enable/disable the links. It's
easy to implement with my layout.
I think some clear and simple examples using swarm with users extracted
from a db will be a very good improvement. (with login page, normal
pages, securized pages and several security levels)
If so, I might upgrade my app to use swarm. But for now it looks too
complicated for just autorizing instantiation.
And last but not least, swarm/wasp are both in version 0.1 beta, I'd
prefer to wait for a stable release or at least a rc. (my app will be
in production soon)
Thanks
Maurice Marrink a écrit :
Hi,
I'm wondering what exactly about swarm you find difficult or too complex.
Perhaps we can make some improvements.
preventing pages in swarm to be constructed is as complex as extending
SecureWebPage.
Off course you need to create a policy for those 3 types of users,
containing you're secure pages.
About hiding links to pages people are not supposed to come, it will
spare your users from hitting the access denied page.
It tends to annoy people: if the app knows i'm not allowed to go there
then why can i click on that link anyway, etc.
