Re: Transactions..... again!

[Igor Vaynberg]

aspectj is pretty cool, but its expression language is somewhat
limited. for example salve allows

public void somefunction(@NotNull Integer a, @NotEmpty String b) {}

aspectj, at least when i started salve, did not have an expression
that would let you match a function if its argument was annotated with
a specific annot.

also i need things like removing/adding fields and contributing to
clinit. aspectj is great for quickly matching on something and then
adding something around, not for complex bytecode manipulation.

i started out writing salve with javassist, but i got tired of writing
java code in strings. i wanted to be in complete control of bytecode
to make sure it was as efficient as possible so in the end i learned a
bit about bytecode and ended up using ASM.

Forwarding to a servlet

[David Leangen]

Hi!

What's a clean way to forward a request to another existent non-Wicket
servlet?

I have a wicket page that handles user input, then the input should be
processed by the existing servlet. 

Rather than redirecting to an external URL, I thought it would be nice
to just forward the request to the other servlet. However, I'm worried
that this will leave Wicket is some strange state...


Thanks!
David

Re: Tables

[Peter Thomas]

Hi,

I think you should use a ListView.  You can easily nest one within another.
For your particular requirement, you can even consider using a single table
instead of embedding a child table.  By controlling "colspan" the attribute
columns can "line up" in case you need that.  Have a look at this example
which is part of a comparison of GWT with Wicket

http://ptrthomas.wordpress.com/2008/09/04/wicket-and-gwt-compared-with-code/


Thanks,

Peter.

Ok, the Spring annotations/aspects do have a limitation that they need

Cool.  So, why doesn't Salve just use aspects and AspectJ to achieve
what it wants (AspectJ supports the same 3 instrumentation options)?
Did you write your own instrumentation?  Do you not like the
syntax/architecture of AspectJ?  Just curious.  I'm all about writing
stuff my own way. :)

Re: Transactions..... again!

[Igor Vaynberg]

read my email, i said it is possible without salve. salve just makes
it easier by letting you put the annotation on any method of any
class.

salve ships with 3 instrumentation options. there is the agent for
load time weaving, a maven2 plugin for compile time weaving, and an
eclipse plugin for dev time weaving.

i have also recently added something cool for wicket - expression
checking. if you use salve's contract instrumentor you can have it
validate property expressions, so you can do

new PropertyModel(contact, new PE(Contact.class,
"address.street1").toString()) and get an instrumentation, read
compile, time error if there is no contact.getaddress().getstreet1().
doesnt refactor like the proxy idea but is also much more light weight
and works on map and list properties.

 now if your form uses an ldm that loads an entity you dont even need
 an onsubmit, things just get updated automatically because model
 updates happen within a transaction.

 you can do the same without salve but you will have to manually start
 and commit/rollback the transaction.

 this is probably the easiest way if you have a rich model and it
 doesnt invole the somewhat ugly merge call. of course this wont work
 for all forms, but for most i think it should.

Re: Hibernate and DomainLoadableModels

[James Carman]

If you're using Spring, you can inject whatever you want into your
listener.  You can add your listener bean to the list of listeners in
your application context configuration file.

Re: Transactions..... again!

I didn't think so.  My apologies if I misunderstood.  I was talking
about using the spring-aspects stuff and having the AspectJ compiler
weave the aspects into your code at compile time.  Isn't Salve a
load-time weaver?

 I'm using Spring/Hibernate/Declarative Transactions. We try to keep our
 data-models rich and that helps a lot with transactional support
 (services direct the rich-models and commit at the end of the service
 call).

 I still occasionally run into times when I want the onSubmit in a form
 to start a transaction. I've basically decided to just use Spring's
 programmatic transaction demarcation in those areas. Ive seen Igor
 mention Salve, but I could not find any good examples, and I am not very
 familier with Guice.

 Aside from these ideas, has anyone used a different method for starting
 transactions inside of wicket when needed?

 Thanks!

You're probably better off setting up a Hibernate listener if you want
to do audit logging.  Check out the Java Persistence with Hibernate
book for an example (if you have it).

You don't need Salve for that.  You can just use the AspectJ compiler
and weave the transactional support into your form class.

Hibernate and DomainLoadableModels

[Ryan]

I keep running into a similar issue and it comes down to me missing some
fundamental knowledge of Hibernate, but I was hoping someone here could
help point me in the right direction.

Consider a Hibernate model called Child and it has a property called
firstName. Now lets say I use a LoadableModel for the Child and tie firstName 
to a
TextField via a property model.

In Form.onSubmit I want to call some business logic classes and pass in
the Child (so far no problem). Due to the OpenSessionInViewFilter and
LoadableModel the current Hibernate session context has a persistent
Child (that wicket has subsequently called setName on). In this code I
want to be able to query out the Child object as it is in the DB and
compare it to the modified, but uncommitted Child. 

We use this to either create an audit trail or show on the screen:
"Child's First Name changed from X to Y".

In this simple example I could keep track of this in Wicket, but its
harder with more complex relationships.

Is it possible with Hibernate to say give me the Child model from the DB
and not the currently active instance that is tied to the session?

Thanks,
Ryan

Re: Transactions..... again!

[Igor Vaynberg]

with salve you can do a neat thing:

class transactionalform extends form {
   @Transactional process() {
super.process();
   }
}

now if your form uses an ldm that loads an entity you dont even need
an onsubmit, things just get updated automatically because model
updates happen within a transaction.

you can do the same without salve but you will have to manually start
and commit/rollback the transaction.

this is probably the easiest way if you have a rich model and it
doesnt invole the somewhat ugly merge call. of course this wont work
for all forms, but for most i think it should.

Transactions..... again!

[Ryan]

I know this topic has come up a few times on the list but I wanted to
rehash some ideas again.

I'm using Spring/Hibernate/Declarative Transactions. We try to keep our
data-models rich and that helps a lot with transactional support
(services direct the rich-models and commit at the end of the service
call).

I still occasionally run into times when I want the onSubmit in a form
to start a transaction. I've basically decided to just use Spring's
programmatic transaction demarcation in those areas. Ive seen Igor
mention Salve, but I could not find any good examples, and I am not very
familier with Guice.

Aside from these ideas, has anyone used a different method for starting
transactions inside of wicket when needed?

Thanks!

Re: Turning off SWARM for testing?

[Neil McT]

Sorry - fairly new to Wicket - don't quite follow. Do you mean subclass
AuthenticatedWebSession in the test environment to always return true on
authenticate() ? How would this play with SWARM?

I have just found an, albeit more convoluted, solution

My TestApplication class overrides setupStrategyFactory to return a dummy
strategy factory which is configured with a stub implementation of
ISecureComponent. Digging about in the SWARM code it seems that only
subclasses of this stub will be authenticated - and as there are no
subclasses, authentication has been essentially circumvented.

Not the prettiest solution but it _seems_ to work.

But it did remove the need for me to manufacture a unique hive-key per

sorry, i dont know anything about swarm itself. maybe during test you
override setuphive() and give it a policy that allows everything and

Re: error handling and redirect (was: how to logout and redirect)

[Erik van Oosten]

It mainly depends on whether you would like to allow a refresh, and how 
sensitive you are to nice URLs. The key difference is that the user will 
see that he/she lands on another URL when you called setRedirect(true). 
After that a refresh will reload the error page. With redirect set to 
false, the user can try the original URL again.


Regards,
   Erik.

Really appreciate your help.

The setRedirect(true) call tells Wicket to use the Servlet API to
issue a redirect to go to the response page as opposed to just
streaming it back as the response to the current request.

Sorry not sure what you mean by 'swarm auth strategy'

My application class extends SwarmWebApplication and the only SWARM specific
methods it overrides are getHiveKey() and setUpHive() - where I add the
policy file. Is it one of these that I should be 'nulling out' for testing?

Thanks.

have an overrideable method on your application boolean
issecurityenabled(), and only add swarm auth strategy if it returns
true. that way during tests you can give tester a subclass of your app
that returns false.

Turning off SWARM for testing?

[Neil McT]

Is there any way to turn-off / circumvent SWARM for testing?

I'm using WicketTester and any time I attempt to navigate to a protected
page (i.e. implements ISecurePage) I get bounced back to my login-page.
 
I'd prefer not to have to go to the lengths of 'logging in' a user, just for
tests as I'd prefer my unit tests to be as focussed as possible.

Any help much appreciated.

Neil.

Re: Wicket not secure?

to be totally explicit, the third sentence should probably say "explicit

the last sentence is outdated as wicket provides URL encryption if you want
it

Re: Wicket not secure?

[Igor Vaynberg]

afaik wicket is one of very few frameworks to offer this out of the
box if not the only one. this feature is really a side-effect of how
wicket works :)

for complete security you probably want to have a look into
CryptedUrlWebRequestCodingStrategy, it completely encrpypts the urls
so they look something like
?x=sdf7saf7sd9f7sd89f7sadf7sa789sd7f89sdf7sssdf and offers csrf
protection.

Tables

[michael4321]

Hi,

   I have a table within a table, basically each row has some main details,
and the sub table lists attributes for the row.  The issue I'm having is
that not all attributes should display for each row, and I'm not sure how to
get around this.


ex.

   
   
   





   
   

   
some rows I'd like to only display attrib1 and attrib2 and other rows I may
display all three,...
I'm using a RepeatingView to populate the table, I'm guessing that this is
probably wrong.  

Is there a way to  have a a list dependent upon another list? like below?

Ok, cool!  Sorry, but I haven't had a chance to look at the code.  The
10k folders thing just jumped out at me.  It doesn't really matter to
me one way or the other if this is customizable.  I was just trying to
make a friendly suggestion.  Wicket has had some knocks for not being
very customizable compared to other frameworks (not saying I agree
with them; no flame intended).  So, when adding features, it's
important to add in customization hooks, especially if they're easy to
do (and it seems like this one should be).

Re: Wicket not secure?

[Igor Vaynberg]

urls are session-relative. meaning a url you get from one session will
not work in another. if you want urls to work across session, such as
the case with bookmarkable pages - http://server.com/view/profile/15 -
you must explicitly mount the page to the url.

Re: CSS and variation

[James Carman]

Take a look at this document.  It should help you.

http://cwiki.apache.org/WICKET/localization-and-skinning-of-applications.html

You'll probably want to use different "styles" for your different skins.

Re: DropDownChoice and lazy loaded choices

[James Carman]

Right, I was going to suggest you not use multiple.  That does lead to
problems if you're not careful.

Anyway, in your situation, you're holding onto a "detached" object?
And, it's somehow getting loaded (huh huh, I said "getting loaded")
somewhere else during the same request?

 This was several years ago though, and I have the impression that a

 I guess it all works fine when you know what you're doing :-)

CSS and variation

[Mathias P.W Nilsson]

I'm looking at  http://www.csszengarden.com CSS Zengarden  that uses the same
html markup and only alters the css. I would like to use variation like this
and I'm wondering what my approach should be?

I set Session.setVariation( String variation ) in my session object
I have the same java and html file
How can I create different variation of css files?

Re: Scalability & PageMaps

[James Carman]

>From Matej's previous email:

e.g. int hash = computeHash(sessionId) % 100;
String folder = "" + hash + "/" + sessionId;

That's where I got the 100 thing.  So, what we're talking about here
is potentially 10k "buckets" for session store folders.  There would
be  the potential for 10k top-level folders.  Perhaps smaller sites
would wish to not have the potential for 10k folders?  I don't know.
A smallish site might just want to make the divisor 1, if they don't
have many users.  The folders won't be removed even after all of their
subfolders are removed, right?

Are you using the single session setting on OSIV?  Or, are you using

I don't you you want to come anywhere near the amount of  32k files in
single folder.
I wouldn't assume that every filesystem can handle such amount without
performance problems.

Re: DropDownChoice and lazy loaded choices

[Cédric Thiébault]

In fact my example with the collection updating automatically was
wrong... because, as it was said, the transaction is not committed at
the end.

But I remember other kind of problems when I wanted to save and commit
my modified entities after I loaded and associated them during the
request (via OSIV) :
I was passing a graph of persistent objects to the manager and I had
exception like "a different object with the same identifier value was
already associated with the session".
I tried then to use a merge but in this case I had other exception (I
don't remember exactly which one)...

If I don't use OSIV and pass a graph of transient object, it works fine!

It must be something wrong with my hibernate mapping but it hard to locate :-(

from what i´ve googled, all FS i could think of either dont care, or 
limit to (almost) 32k or more. (could be wrong here, anyone?)



hopefully the hash is a bit equally divided so the first dir will make 999
dirs before it complete fills up for example 1 dir


looking at String.hashCode i would say yes, especially for small Strings

Re: Scalability & PageMaps

[Johan Compagner]

yes having this configurable looks ridiculous to me.

The only thing that i can think of is is the 32K limit for all the
filesystems?
or does another filesystem has another limit?

Because if that is the case we could make it so that for example we do 3
(1000 dirs) or 4 (1 dirs) numbers per dir

hopefully the hash is a bit equally divided so the first dir will make 999
dirs before it complete fills up for example 1 dir
hope it balances

one more char per directory can wreck the 32k limit, one less would give

i´d say reasonable, but i really would not mind to see this configurable.

AW: Wicket and Mootools?

[Agent Mahone]

O, thank u very much for ur comments.

I have some questions to you:

1. What is the package mini under contribution package for?
What is the difference to package contribution/wicket-mootools???

2. I also noticed that wicket offers you "scriptaculous" and "jquery".
   Is there any comparsion between that frameworks?

I´ve seen that scriptaculous is much more easier to understand and difinitely 
to use.

Thanks again for any comments

Wicket sample application

[superoverdrive]

Hi there!

I am looking for a Wicket sample application (e.g. something like a "Petshop") 
- ideally once that includes things such as: User registration, Admin area, 
editing data (e.g. with Ajax auto-complete) and an example of displaying data 
in a table that is read incrementally from the database (e.g. displaying huge 
database tables without crashing)

On the Wicket homepage there are just small examples, but no complete websites 
done in Wicket

Something like:

http://bakery.cakephp.org/categories/view/3

would be good for Wicket:

Thanks!

Navigating from a Modal Window

[Eyal Golan]

Hi,
I have a Modal Window that uses a page.
I want that when the user presses OK in the page, there will be a navigation
to a new page and the modal window will be closed.
The navigation should be not in the modal window but in the original page
itself.
Here's what I did:
In the page that is the content of the window:
EurekifyAjaxButton okButton = new EurekifyAjaxButton("ok") {
private static final long serialVersionUID = 1L;

@Override
protected void onError(AjaxRequestTarget target, Form form) {
super.onError(target, form);
target.addComponent(feedbackPanel);
}

@Override
protected void onSubmit(AjaxRequestTarget target, Form form) {
*window.setReportSrcUrl(getParametersPairsForReport(),
getReportName());*
window.close(target, true);
}

};

In the window:
public final void setReportSrcUrl(Map
parametersPairsForReport,
String reportName) {
if (reportPage == null) {
reportPage = new ReportPage(this, link);
reportPage.setReportSrcUrl(parametersPairsForReport,
reportName);
setResponsePage(reportPage);
} else {
reportPage.setReportSrcUrl(parametersPairsForReport,
reportName);
}
}

Where reportPage is a class member.

I thought about keeping a reference to the page where the link that opened
the popup was.
And then do the setResponsePage on it.

Is there a nicer way?

Re: SessionStore and Detachable Models

You should use LoadableDetachableModel where possible to avoid stale
data (and to preserve memory).

Re: ModalWindow gives Exception

Maybe you are looking for this jar

http://sourceforge.net/project/showfiles.php?group_id=97367&package_id=104212

I'm using version version 1.4... Which is the one maven installed for me...

SessionStore and Detachable Models

[carloc]

hi everyone, 

if i use the secondlevelcachesessionstore wicket writes session state into
the disk
instead of the httpsession right? It is also the one that is used by
default.

so is it safe for me to not use abstractdetachablemodels and just use
compoundpropertymodels since memory is not that big a concern anymore

  * Now a real archetype using the new archetype-metadata.xml

If you dont know about iolite heres what it are:

A maven archetype that generates a two module project with spring and
JPA-hibernate setup much like the wicket quickstart. This means that you can
run a maven command and get you running in no time with wicket, please see

IgnoreAjaxRequestException/EmptyAjaxRequestTarget: a way around it?

[Pointbreak]

I have a page that in a piece of javascript code does some updates to
the page dom, and then does a wicketajaxpost request. This all works
fine, unless the dom updates trigger loading of page-bound resources
(e.g. images). As it turns out wicket detects during the ajax requests
that other requests are made for the page (the images with their
resourceimage). In that case it just plainly substitutes the ajax
request with an EmptyAjaxRequestTarget, ignoring the original request
without warning.

Is there a way around this?

Re: Localized string retrieved with a warning message

Don't call getString() on your final StringResourceModels, rather just pass
the models to the links, then you shouldn't bet the warning anymore

Re: DropDownChoice and lazy loaded choices

[Maarten Bosteels]

Hi,

I never really used OpenSessionInViewFilter, but I remember Juergen
Hoeller saying that he sometimes wished he never wrote OSIV because of
all the potential side-effects.
At the time a ridiculous big percentage of questions on the spring
forum where about OSIV.

This was several years ago though, and I have the impression that a
lot of people are using OSIV now without problems.

I guess it all works fine when you know what you're doing :-)

Localized string retrieved with a warning message

[Azzeddine Daddah]

Hi,

I get the following warning message when trying to retrieve a localized
string: *Tried to retrieve a localized string for a component that has not
yet been added to the page. This can sometimes lead to an invalid or no
localized resource returned. Make sure you are not calling
Component#getString() inside your Component's constructor. Offending
component*

This how my code look like:
public class NavigationBarPanel extends Panel {

private static final long serialVersionUID = 1L;
/** The navigation bar links */
private final String MENU_MENU = new
StringResourceModel("navigationbar.menu.home", this, null).getString();
private final String NUMBER_POOL_MENU = new
StringResourceModel("navigationbar.menu.numberpool", this,
null).getString();
private final String NUMBER_POOL_LOG_MENU = new
StringResourceModel("navigationbar.menu.numberpoollog", this,
null).getString();
private final String DEFRAGMENT_MENU = new
StringResourceModel("navigationbar.menu.defragment", this,
null).getString();
private final String SEARCH_MENU = new
StringResourceModel("navigationbar.menu.search", this, null).getString();

public NavigationBarPanel(String id) {
super(id);
addLinks();
}

private void addLinks() {
addLink("home", MENU_MENU, HomePage.class);
addLink("numberPool", NUMBER_POOL_MENU, NumberPoolPage.class);
addLink("numberPoolLog", NUMBER_POOL_LOG_MENU,
NumberPoolLogPage.class);
addLink("defragment", DEFRAGMENT_MENU, DefragmentPage.class);
addLink("search", SEARCH_MENU, SearchPage.class);
}

private void addLink(String id, String title, final Class pageClass) {
BookmarkablePageLink link = new BookmarkablePageLink(id, pageClass);
link.add(new AttributeModifier("class", true, new
AbstractReadOnlyModel() {
private static final long serialVersionUID = 1L;

@Override
public Object getObject() {
String currentPageName = pageClass.getName();
String parentPageName  = getPage().getClass().getName();
return StringUtils.equals(currentPageName, parentPageName) ?
"current_page_item" : AttributeModifier.VALUELESS_ATTRIBUTE_REMOVE;
}

}));
link.add(new Label("title", new Model(title)));
add(link);
}
}

Could you please tell me why am I getting this warning. I use the same
strategy to add localized string to my pages but I don't get warnings.

Re: newbie: best practice for not rendering component?

[Igor Vaynberg]

a) interface ierrorlistener { void error(string msg); }
b) abstract class errorreportingdataprovier implements idataprovider {
   private component owner; // setter
   protected abstract internaliterator(int s, int c);
   protected abstract void reporterror(ierrorlistener l, exception e);
   public iterator iterator(int s,int c) {
  try { internaliterator(s,c); }
  catch (exception e) {
 ierrorlistener l=owner.findancestor(ierrorlistener.class);
 reporterror(l,e);
 return new emptyiterator();
   }
}
c) let your dataprovider extend the one in (b)
d) make sure whatever it is you use to render the message renders
after the dataview.

hi james


Do you think that modulus number should be customizable?  So, for now,
you mod your number of users by 100.  But, for larger sites, they
might want to mod it by 1000 or 256 or whatever.


actually, the first level dir is created from hash%1 and the second 
from hash/1%1, while the third level dir is the sessionId 
itself. i do not see a need for more, do you?


why should anyone care of the inner structure of the filestore, as long 
as it cannot lead to problems?
