Re: How to encrypt/obfuscate resource reference?
As I briefly mentioned before, class aliases are, IMO, a terribly unreliable thing to maintain. Every time someone comes up with new component that uses resource reference they must not forget to go and register the alias for it. I'm predicting a 100% probability that soon enough someone will forget it and it'll go into production -- thus defeating the entire purpose behind the encryption/obfuscation :) And to comment on what Antoine is saying -- I'm not entirely sure what did you mean, but if I tried to implement encryption at CryptedUrlWebRequestCodingStrategy, I will have to ensure that encrypted URL will have format that will be fully parseable after browser appends relative CSS URL to it. This is manageable by, say, encrypting only the section of the path containing the class name. But then I'm completely unsure as to how properly decode it / fake request for Wicket. The existing code only 'fakes' parameters string -- but there are API methods that deal with request path as well, and if those are not correct, I'm not sure what issues that may cause. Bottom line -- it must be possible to do encryption at CryptedUrlWebRequestCodingStrategy, but it will take some serious digging to make sure all parts fit correctly. It would be far easier to e.g. automatically add alias in SharedResources method that deals with assigning the name to shared resource -- the only thing it'll require is to modify Application class so that e.g. getSharedResources() is not final. But I'm still hoping for some 'easy' solution that doesn't entail modifying Wicket source code to avoid headaches when upgrading. bgooren wrote: The easiest way around this is to specify http://wicket.apache.org/docs/1.4/org/apache/wicket/SharedResources.html#putClassAlias(java.lang.Class, java.lang.String) class aliases .

Re: FormTester and Select component?
Thank you for the reply. Unfortunately this is not easier for me since
we already have this function implemented using the Select component.
If there is no way of getting FormTester to work with that component
i'll have a look at your code - i really want to have this test
automated without having to use a heavier test framework.

Re: Re: FormTester and Select component?
You could easily extend WicketTester and FormTester to support selecting in org.apache.wicket.extensions.markup.html.form.select.Select. Take a look at the public void select(String formComponentId, int index) method in FormTester and public FormTester newFormTester(String path, boolean fillBlankString) in BaseWicketTester on how to do it.

ListView + dynamic database Model
Sorry for my poor english ;)
I have ListView and model like below. I need tabs to reload sometimes,
so my model is dynamic and get tabs from database.
But i see that something is wrong. When i want to get Tab object by
getModelObject() in populateItem method i suppoused that i got it
directly, but i see that all the times the getObject() method of model
is triggered making for all items new list (new db request) !
How to get Tab objects for items without making wasting time database
request ???
IModel model = new IModel() {
public Object getObject() {
System.out.println(getObject...);
...
// getting list from DB
ListTab list = ;
return list;
}
public void setObject(Object object) {}
public void detach() {
}};
ListView tabs = new ListView(tabs, model) {
@Override
protected void populateItem(ListItem item) {
item.getModelObject(); /* - new
list, and new list,
and new list.. :(
}
};

That's exactly what is supposed to happen, as getModelObject() is just a
shorthand for getModel().getObject(). And in your getObject(), you do
the database request.
If you need to avoid those database reloads, look into
LoadableDetachableModels.

Re: How to encrypt/obfuscate resource reference?
Sorry, I overlooked that part of your original post. I've been toying with the same idea, since class aliases are bound to cause problems as projects grow bigger. As long as the aliases are user-generated, they might not be unique. So I had a quick look at the source code of WebRequestCodingStrategy, and I think it should be possible to create a solution for your problem quite easily: 1) subclass WebRequestCodingStrategy, and use it by overriding newRequestCycleProcessor() in your application, and return a subclasses WebRequestCycleProcessor which returns your custom WebRequestCodingStrategy in the call to newRequestCodingStrategy(). Quickest solution is to create an anonymous inner class for the custom WebRequestCycleProcessor 2) override the http://wicket.apache.org/docs/1.4/org/apache/wicket/protocol/http/request/WebRequestCodingStrategy.html#encode(org.apache.wicket.RequestCycle, org.apache.wicket.request.target.resource.ISharedResourceRequestTarget) encode method which deals with shared resources, and implement encryption (or simply an obfuscated, stable alias for classes) 3) override http://wicket.apache.org/docs/1.4/org/apache/wicket/protocol/http/request/WebRequestCodingStrategy.html#addResourceParameters(org.apache.wicket.Request, org.apache.wicket.request.RequestParameters) addResourceParameters() and implement decryption Sergey Olefir wrote: As I briefly mentioned before, class aliases are, IMO, a terribly unreliable thing to maintain.

Ok, scratch that comment too... I see Antoine dug up an old thread of yours where you already found out about the possibility to override WebRequestCodingStrategy.

Hi, Ernesto! This is most likely the way I'll do the thing. I have a quartz scheduler and will arrange a recurring job that will clean files older than a day for instance. Thank you all!

Re: autolink not work ?
kinabalu wrote: Index1 and Index2 are generated as italics because you are on the same page. If you use autolink and you're on the same page, they show up as italics Index3 doesn't work because you've got a slash preceding the package name.

Re: How to encrypt/obfuscate resource reference?
Take a look at the spring component scanner for an implementation of
how to search the class path. Then it is just a series of
ResourceReference.class.isAssignableFrom(clz) queries and applying
your specific logic.
For example we use the following code to scan for specific patterns in
html files (such as style= attributes in html code, which we consider
illegal—use classes and stylesheets instead).
ResourcePatternResolver, PathMatchingResourcePatternResolver are
classes that comes from Spring.
ResourcePatternResolver resourcePatternResolver = new
PathMatchingResourcePatternResolver();
for (String packageName : getPackageNames())
{
String usePackageName = packageName;
if (!usePackageName.endsWith(.))
usePackageName += .;
String filePatter =
ResourcePatternResolver.CLASSPATH_ALL_URL_PREFIX
+ ClassUtils.convertClassNameToResourcePath(usePackageName)
+ **/*.html;
try
{
Resource[] resources = resourcePatternResolver.getResources(filePatter);
for (Resource resource : resources)
{
if (resource.isReadable())
{
ListString matches =
getMatches(resource.getInputStream(), pattern);
String fileName = resource.getURI().getPath();
if (errorWhenFound)
{
if (!matches.isEmpty())
addError(fileName + : + matches);
}
else
{
if (matches.isEmpty())
addError(fileName);
}
}
}
}
catch (IOException e)
{
addError(e.getMessage());
}
}
assertNoErrors(message);

Re: How to encrypt/obfuscate resource reference?
I admit I didn't research in-depth what you've suggested, but from the quoted piece it seems that your suggestion will find all subclasses of ResourceReference. But to actually test that all resources are properly mapped, it would be necessary to locate all invocations of the ResourceReference constructors and scan their parameters. I have hard time imagining how it could possibly work without resorting to AspectJ (or AOP in general). Also the same problem may be relevant for e.g. Image() and possibly other stuff. Basically, unless I completely misunderstand what you're suggesting, I don't really see how such scanning might work.

Page Expired
Hi, guys. I've got problem with 'Page Expired' message. I'm developing application that is worked on GAE. It has one page with help content. There is two help pages. Help page contains two separated divs. One div for table of content, second - for content. When user clicks on link, page is reloaded with appropriated content. So, when I load this page first time all works fine. But when I click on any link, I get 'Page Expired' message. I set log level to debug. Here is some messages: 13:46:14,140 DEBUG [org.apache.wicket.Session] - Getting page [path = 3:tabpanel:panel:toc-panel:help.panel.navigation:1:help.panel.link, versionNumber = 1 13:46:14,141 INFO [org.apache.wicket.Page] - No version manager available to retrieve requested versionNumber 1 13:46:14,141 INFO [org.apache.wicket.AccessStackPageMap] - Unable to get version 1 of page [Page class = com.dominity.web2care.wicket.pages.BasePage, id = 3, version = 0] 13:46:14,142 DEBUG [org.apache.wicket.RequestCycle] - setting request target to [bookmarkablepagerequesttar...@974813593pageclass=org.apache.wicket.markup.html.pages.pageexpirederrorpage] So, could you explain me what's wrong with this and what is it about: No version manager available? If you'd like I show you source code and markup. BTW, please, bear in mind, that the same page works fine of GAE SDK without any page expirations, but on server side I get always Page Expired message. Best regards, Alexander.

}
};
final WebMarkupContainer exportedFileLinkHolder = new
WebMarkupContainer(link_holder);
exportedFileLinkHolder.setOutputMarkupId(true);
exportedFileLinkHolder.add(exportedFileLink);
rightForm.add(exportedFileLinkHolder);
rightForm.add(new AjaxButton(export_button) {

@Override

PhonebookExporter exporter = getExporter();
exportedFile = exporter.export(uploadFolder);

Not sure... but could you try something like:
DownloadLink downloadLink = new DownloadLink(link_id, new
AbstractReadOnlyModelFile(){

downloadLink.setOutputMarkupId(true);
and make linkModel a member variable? This way file will be refreshed.

Re: Page Expired
Alexander, Maybe this has to do with the persistence store you are using to make Wicket work on GAE not actually persisting your pages to a location that they can be retrieved again? I know by default the DiskStore that Wicket uses won't work on GAE, so I imagine you plugged something else in -- if you did and it's just tossing out the previous versions of the pages, that would explain what you are seeing no version PREV_VERSION of page errors. What store do you have configured? -R On Tue, Mar 2, 2010 at 6:59 AM, Alexander Monakhov domin...@gmail.comwrote: Hi, guys. I've got problem with 'Page Expired' message. I'm developing application that is worked on GAE. It has one page with help content. There is two help pages.

So, when I load this page first time all works fine. But when I click on any link, I get 'Page Expired' message. I set log level to debug.

[newbie] Wicket, Spring, Hibernate and transactions in views.
All,
I've got a bit of a newbie Wicket question involving Spring, Hibernate
and transactions.
The question that I can't seem to find an answer to;
Can a view be a created/injected/aop'd like a spring bean so that it
honours @Transactional methods for hibernate?
An example;
public class HomePage extends WebPage {
@SpringBean // this is working fine
private SessionFactory sessionFactory;
public HomePage(final PageParameters parameters) {
this.init();
}
@Transactional // this is not working
public void init() {
Criteria criteria =
sessionFactory.getCurrentSession().createCriteria(MyEntity.class);
ListMyEntity myEntities = criteria.list();
for( MyEntity myEntity : myEntities ) {
// where subEntities is a lazy collection
for( SubEntity subEntity : myEntity.getSubEntities() )
{
// ...
}
}
}
}
I've been reading Wicket In Action book, various places on the net and
of course, emails on the subject on this list and this particular
tutorial;
http://wicketinaction.com/2009/06/wicketspringhibernate-configuration/
And I'm still wondering, is this something that is actually possible? I
could full understand that it wouldn't be - i.e. that the injector only
works for Spring injection dependency and not AOP or anything else. So
you inject your dependencies - and they have transaction support etc.
But that means I'll be having to force fetching of lazily fetched
children from outside the views themselves, which is obviously very
painful. It would be so much easier to have transaction support in the
view itself and not have to delegate.
Any help would be greatly appreciated.
The error message I'm receiving is;
Caused by: org.hibernate.HibernateException: createCriteria is not valid
without active transaction

org.hibernate.context.ThreadLocalSessionContext$TransactionProtectionWra

Re: How to encrypt/obfuscate resource reference?
Good to know I contributed something useful to this thread haha. The code looks like the stuff I had in mind. You gotta love Wicket for making it quite easy to do this stuff; Although the URL encoding/decoding can be quite complex for beginners, but that is likely to be fixed in the future (I've had a look at Matej's wicket-ng implementation, and it looks very promising).

But I want to have the link invisible on startup (because the file's

exportedFileLink = new DownloadLink(exported_file_link, new

I'd recommend you to make your transactional control in your services and
call them from your pages instead of trying to control it in your view.

RE: [newbie] Wicket, Spring, Hibernate and transactions in views.
I'd recommend you to make your transactional control in your services
and call them from your pages instead of trying to control it in your
view.
I'd agree in terms of good design, but I'm coding something for myself
- and I'm trying to make it easy and as little time consuming as
possible. So, yes, transactions in the presentation layer is bad - but
it's only read-only transactions, so I'm letting myself off! ;)
Having the transactionally controlled service methods, individually
instantiate all child entities by hand is also time consuming and would
potentially harm performance (if the view didn't need the children, for
example).

RE: [newbie] Wicket, Spring, Hibernate and transactions in views.
If you aren't concerned with good design then I wouldn't worry about
transactions at all. Especially if you are doing read only data retrieval.
Once you get the code working the way you want you can always add
transactions later and refactor the code into your service methods. That's
the agile method anyway. :-)

RE: [newbie] Wicket, Spring, Hibernate and transactions in views.
I'm not DB expert, but why are you using transactions for read only
(SELECTs) queries?
If you aren't concerned with good design then I wouldn't worry about
transactions at all
Because you need the transactions for lazy fetching of child elements in
hibernate.

you inject your dependencies - and they have transaction support

Hi all, I'm comparatively new to Wicket and have a question about the wizard button labels. I'm using a Wizard with an AjaxButtonBar and AjaxButtons for previous and next. I would like to change the labels on the last step of the wizard of the cancel and finish buttons. I know how to change those labels for the whole wizard, but it escapes me how do change them in the last step only. Is there any elegant solution to this? Thanks, Natalie
Re: [newbie] Wicket, Spring, Hibernate and transactions in views.
Consider to use OpenSessionInViewFilter
http://static.springsource.org/spring/docs/1.2.9/api/org/springframework/orm/hibernate3/support/OpenSessionInViewFilter.html
The doc: Intended for the Open Session in View pattern, i.e. to allow for
lazy loading in web views despite the original transactions already being
completed.

Re: [newbie] Wicket, Spring, Hibernate and transactions in views.
Introduce AspectJ and spring-aspects into your build. You can see an
example of it in my wicket-advanced sample project:
http://svn.carmanconsulting.com/public/wicket-advanced/trunk/
Then, AspectJ will weave the transaction support into your
Page/Component classes like you want. There are limits on what type
of methods can be transactional, though. I would also recommend the
OpenSessionInView filter (which my example project also uses).

Extended Form Question
Hi, I have extended the Form component to include a visitor that adds some behaviors to required fields so that the validation errors are rendered next to the corresponding fields. My problem is that I have a form that has a form level validator that is not specific to a component. So I still need a feedback panel to be included. My problem is that the feedback panel also lists all of the component's individual errors. How can I make my feedback panel not filter out form level messages but filter out component level messages? Thanks, Josh
Re: Extended Form Question
You would instantiate your FeedbackPanel with an IFeedbackMessageFilter: http://wicket.apache.org/docs/1.4/org/apache/wicket/feedback/IFeedbackMessageFilter.html Perhaps you would check to see if the form itself is the reporter of the message?

My problem is that I have a form that has a form level validator that is not specific to a component. So I still need a feedback panel to be included. My problem is that the feedback panel also lists all of the component's individual errors. How can I make my feedback panel not filter out form level messages but filter out component level messages?

You can always use:
field = new Field(...) {
@Override

}
