Re: model detached many times
As models are nested this is not possible with the current setup. If a model nests another model, the nesting model is responsible for calling detach on the nested model. Multiple models may nest the same model. So the best thing to do for now is to have some flag to see if you're already detached. In getObject the flag is cleared. For most models however, it should not matter if they're called multiple times; the typical thing you do in detach is set a field to null. Regards, Erik. James Carman wrote: No, he means *all* models. The idea would be that Wicket would look for fields of type IModel (or its descendants) on components/pages. If it sees one, it would automatically detach it. On Mon, Jul 13, 2009 at 3:47 AM, Vladimir Kkoval...@gmail.com wrote: Martijn, you probably mean how chained models would be detached.

Updating an inmethod grid, looking for hints
Hi, How can I trigger an inmethod grid to do a /complete/ update of itself? The only thing that I see is markAllDirty(). That will update the items currently in the list, but it will /not/ get new items from the data provider. I researched the code for quite some time but I must have been looking at the wrong parts as I found no hook to get this done. The most I could do was call detach() on Body, one of the inner classes of a grid. But on screen, that would only update the number of items in the lower toolbar, not the items in the grid themselves. More ideas? Ideally, imho, the grid should respond to modelChanged(). But I have still no clue what should be in that method.

Hi Jim, You should do 1 in any case :) Point 2 is not so hard. Just download the file with HttpClient or the like. While you're reading from the stream you have to count bytes.

Re: Creating a form dynamically
This might be useful: http://herebebeasties.com/2007-08-17/wicket-bean-editor/ Regards, Erik. Ryan LaHue wrote: I'm trying to build a form dynamically and am having a little problem. Basically I have a class that takes a ListFormComponent and then passes them into a ListView for display on screen. The problem is that they were created elsewhere and I have no control over two things: 1) The order/type of each FormComponent 2) The wicket:id that was chosen for them when the FormComponents were created I think I've solved 1) by creating wrapper classes for each supported FormComponent type... for example, I have a DropDownChoicePanel which simply adds the DropDownChoice it is passed to its html, which is simply a select wicket:id=component/select. This way I can simply wrap each FormComponent in the list with a panel and add all the panels to my listview rather than the components themselves -- this solves the problem of homogenizing the listview's HTML. But 2) is causing me problems, because unless I require all FormComponents to be given a wicket:id which is prespecified and is the same as that in the DropDownChoicePanel (wicket:id=component) then it will not work. Am I going about this all wrong? Is there any way I can receive a FormComponent and then change its wicket:id so that it will always be component in my ListView? Or is there a solution for this problem already?

http://cwiki.apache.org/WICKET/windows-guide-to-installing-wicket-on-eclipse-with-maven.html
Everything went fine up to the point of running a project. I tried
Wicket version 1.4 rc4 and 1.3.6.
Trying to reach localhost:8080 displays an 503-Error...
The console told me the following:

ROSSV01 is the name of the networkserver where my userdata is stored.
I have no clue
why Maven(?) chose that directory... However the URL is false:
Right URL:
\\ROSSV01\Users\mypersonalusername\.m2\...
Wrong URL:
\\ROSSV01\ROSSV01\Users\mypersonalusername\.m2\...
So I'm pretty stuck here. Is it a Wicket error? Is it a Maven error?
Jetty error? Where could I change the URL using eclipse?
Right now I am pretty confused here...
Would be great if somebody can help me out...

So I copied the CSS in index.html between style tags. This helped
but there is still one problem:

even though the picture n1.gif is present in the same directory as

Re: absolute urls in form action
Hi Steen, Starting Wicket 1.4-rc1 plus a patch you can let Wicket make all URLs absolute. See http://issues.apache.org/jira/browse/WICKET-1974 for more details. With some tweaks you can make the shown code work for any context (not just the root context). Regards, Erik.

Re: Wicket in Action vs the other main books
David, Wicket in Action describe how to integrate with Spring and Hibernate. Databinder.net is LGPL, you can choose and copy code you like. Updating selected code to recent wicket version should be fairly easy. Regards, Erik. David Brown schreef: Hello Wicketers, I am in the throes of a decision to buy the Wicket in Action book. There are a couple of other books but the little time I have lurked on this ML I have noticed the Wicket-in-Action authors are fielding some of the issues on this list. The reason I need to hit Wicket as hard as I can is I have already dismissed 3 other MVC frameworks that I have evaluated over the past two weeks. I have also evaluated 3 end-to-end MVC frameworks based on Wicket. End-to-end means: (HTML UI)(Java POJO middleware)(Hibernate|iBatis)(MySQL). I have dismissed all of the so-called end-to-end MVC frameworks except: databinder.net. The databinder.net framework is a great piece of software based entirely on Wicket and Hibernate. The only caveat is databinder.net appears to no longer enjoy a community type support. And, in fact, databinder.net does not seem to be supported in any way including the original author. So, betting the farm on databinder.net is problematic and this brings us to the question of: does the Wicket in Action book (or any Wicket book) discuss the coupling together of Wicket and something like Hibernate or iBatis to a restructured database for the purposes of rewriting an existing web app. The current web app run-time for the company I am working for was written using a code-generator.

In Jersey it's also possible to serve (dynamic) HTML through a standard templating engine, I'm doing this currently and achieving very high scalability while keeping things simple. The caveat with this approach is that you are stuck to the classic templating model and components don't really exist apart from whatever jQuery/ExtJS stuff you wire up manually.

Re: Wicket architecture diagram?
Subbu, Very good that somebody picks this up! At this very high level pages and components are basically just parts of a component tree. A page is just the root of such a component tree. I would therefore recommend replacing the 'page' and 'component' icons by a single stack of 'component tree' icons. The session store is not related to the loadable detachable models. Loading data is entirely the responsibility of the model implementation. What is not clear from this image is that the responsibility to put/get the current page (component tree) in/from the session store lies with the RequestCycleProcessor, not the component tree itself.

Re: Managing Pagemaps
Subbu, If you write a Wicket application you never worry about session cleanups. Only Wicket puts stuff in the session and only Wickets removes it again. Wicket really does an excellent job here. I have never found any reason to tweak this. That said, you as a programmer have the responsibility to keep session size usage low. In particular you must make sure that your models do not retain too much data. Luckily this is easy by using detachable models.

Re: Security in a Spring Wicket layered application
Hi Kent, Go with something that enables authorization in the service layer (e.g. Spring Security, jSecurity, ...). Next base your custom wicket authorization on the authentication store of the chosen base technology. Spring Security uses a thread local as authentication store and has a servlet filter to copy the authenticated user to/from the session so that the authenticated user is handily available during a request and properly stored afterwards. Authentication itself can be implemented from Wicket in a custom way (e.g. a username/password form). On success you just store the authenticated user in the authentication store. Regards, Erik. Kent Larsson wrote: Hi, I know there has been some discussion on this. But I've had a hard time deciding how this project should use security anyway. The application in question is layered into three layers for presentation, services and persistence using Wicket, Spring and Hibernate. What we need: - Authentication - Authorization on pages, components - Authorization before being able to run methods in the service layer - Authorization for viewing/editing some domain objects using Access Control List's (ACL's) I have read Wicket in Action and it's custom security solution has some pros: - It's quite easy to understand - We have a lot of freedom in how to do authentication and authorization And some cons: - I don't know how to authorize calls of specific methods, and thus - All security will be in the presentation layer - It won't be usable if we want security on web services later (which we do not need now, so maybe this can be disregarded) It would be nice if we could have a common solution to our security needs that integrates well with Wicket and Spring.

Re: Architectural dilemma: Wicket + REST (JSR311)
Wicket is all about stateful applications (though stateless stuff is useful and is supported). REST is all about stateless resources (though you sometimes need stateful hacks for login/authentication). Given these premises, I would not implement REST resources with Wicket (well, maybe if you have just 1 or 2). If you want to be more powerful, I would rather implement REST stuff with Spring MVC. Currently I am using Restlets which works very well also. Jersey sounds fine as well. Regards. Erik. Fabrizio Giudici wrote: Hi there. My application, along with the usual HTML pages generated with Wicket, should also expose some RESTful services. These REST calls should return documents of various types: images, movies, as well as RDF/XML and N3 and so far. In an architectural spike I've made, I've used Jersey (implementation of JSR-311) and of course the two things can co-exist; so everything works and I don't have technical problems to solve (at the moment). The dilemma is architectural: I'm guessing whether getting JSR-311 in increases complexity in a way that can be avoided. In other words, could Wicket be able to serve the same facilities provided by JSR-311 (I mean, the subset I need)? Actually, Wicket can serve non-HTML contents by means of DynamicWebResource, so it seems doable. There are two specific questions now: 1. Security. For HTML pages, protected areas shoud handle login in the WIcket way (or what I assume is the normal Wicket way), i.e. rendering a specific HTML login page. For other types of documents, instead, I need HTTP authentication and perhaps in future some token-based approach. The point is that in any case either I deny the access or I give the resource, but I can't send back an HTML login page when the client expects a different document type. Would I be able to handle this with Wicket? 2. Having the same URL delivering different contents according to the Accept header. For instance, http://foo.bar/blah should normally render an HTML page; but if a Accept: text/n3 header is specified, a N3 should be returned. This means that in the former case the default Wicket workflow would be ok; in the latter, a DynamicWebResource should be provided. I think I can solve this using JSR-311: I could implement a super-filter that discriminates on the presence of the Accept: header and dispatches either to the Wicket or to the Jersey filter (of course I would implement a custom URL mount scheme so Wicket accepts the same URL as Jersey). Hints? I'm searching to find ASAP a reason for deciding to keep Jersey or to get rid of it, so I can go on with the development without too many fears of having to change something in future.

The project I'm doing will use Wicket, Spring and Hibernate. I know that Wicket and Hibernate uses Simple Logging Facade for Java (SL4J) and that Spring is using the logging component from Apache Commons. Will they co-exist happily? I thought I would use log4j together with both SL4J and the logging component from Apache commons, do you think that's a good idea? Can I set up them all to output logging data into a common file? Or should I use separate files? Or should I store the logging messages in the database? (I'd rather not, as I find grepping etc on text files quite convenient.) Not strictly Wicket, but for Spring I guess I need some kind of configuration file for the Apache Commons logging component as well where I direct it to use log4j? When I've set these up I guess to see that everything works I set the logging level to INFO as it's fairly certain that all three of the frameworks output some information in that mode? Or is there an even better way to make sure? And my last question. In the project I'm starting, do you recommend that I use SL4J for my own logging purposes? (I thought I would use log4j directly, but that was before I learned a little bit more about logging and a lot of respectable libraries seem to choose the path of a bridge/facade for their logging needs. And if it gets us flexibility without added cost there's no reason not to do it that way.) I'm looking forward to hearing more from you about how you are doing your logging.

Re: Why you should not override isVisible
Martijn, I just went through the source (1.4-rc1) to trace a detach manually and find suspect callers of isVisible. I found none during detach, but I did find one call to isVisible /after/ detach. A simple run confirmed this. The call to isVisible /after/ detach can be found in method ComponentRequestTarget#respond(RequestCycle). That method initiates a detach and then calls page.endComponentRender. This leads to a call to Page#checkRendering which calls isVisibleInHierarchy() and from there isVisible(). Method checkRendering only does something when the debug setting 'componentUseCheck' is enabled (which according to the javadoc is true by default). I vividly remember the pain when I found out that isVisible was called /during/ detach. So I am certain the problem existed at some time in the past (1.2, 1.3?).

Why you should not override isVisible
In the thread Where to process PageParameters I was requested to
explain why I think you should not override isVisible, but rather should
call setVisible in onBeforeRender (slide 100 in my presentation
http://www.grons.nl/~erik/pub/20081112%20Effective%20Wicket.pdf).
There are 2 reasons, but only the second one is really important.
-1- isVisible is called a lot. It is easily called ten times within 1
request
So if you have anything processor intensive going on, it will be a
performance hit. Just doing a simple expression is of course no problem.
(For fun, just set a breakpoint in something like
FeedbackPanel#isVisible and request a page that contains one.)
-2- isVisible can make your model be reloaded multiple times within 1
request
Consider the following case (pseudo code):
MyPanel(id, personId) {
super(id, new CompoundPropertyModel(new
LoadableDetachablePersonModel(personId)));
add( new Label(address) {
@Override
isVisible() {
return getDefaultModel() != null;
}
});
}
The label uses the property 'address' of a person to see if the label
should be visible. The person is retrieved by a LoadableDetachableModel
subclass (LDM) and then wrapped by a CompoundPropertyModel (CPM).
During the render phase, isVisible will delegate getting the address
property to the CPM and this model delegates it to the LDM. LDM will
load the person from the database only once (well until it is detached).
At the end of the render phase everything will be detached. But now
something weird happens. The problem is that isVisible is called during
the detach phase, on the label /after/ the CPM (and therefore also the
LDM) are detached. As isVisible retrieves the model from the CPM, and
therefore from the LDM, it will trigger a reload of the person inside
the LDM.
Now, as visibility is often (if not almost always) determined by a
business object (e.g. very often a LDM) I think it makes sense to avoid

Re: Multi-tap operations in Wicket
Glad that is out of the way :) Wicket and Seam are frequently compared. But I think it is not a fair/possible comparison. We might as well compare TestNG with Mockito, both are about testing but in an entirely different league. Seam's goal (as far as my humble knowledge goes) is targeted at combining a variety of frameworks (in particular EJB3 and JSF). Focus is on managing transactions and passing data around by storing and retrieving it from an array of (untyped) contexts. (Please forgive me if I am completely wrong.) Wicket's goal is to provide a natural OO environment to program a html user interface. (Reusable UI components anyone?) Passing data around is the responsibility of components but is typically done with (fully typed) models. There is no need for contexts to keep state as the entire components are kept as state. This is done by storing complete page component hierarchies to a page map. Usually you have one page map per session. Wicket's transaction support is no better or worse then the next web framework.

Re: IDataProvider Implementation.
Not a good idea for large objects. A few days back I improved load time
of a page from more then 40 sec to about 5 sec by replacing new
Model(object) with a proper LoadableDetachableModel.
Nevertheless, there is no reason to let the LoadableDetachableModel get
the object if you already have it, just pass the object to the constructor!
E.g. see first ctor below.
public class LoadableMemberModel
extends LoadableDetachableModelMember {
@SpringBean
private MemberService memberService;
private long memberId;
//
// Constructor that has object has direct parameter
//
public LoadableMemberModel(Member member) {
super(member);
this.memberId = member.getId();
}
*
*public LoadableMemberModel(long memberId) {
this.memberId = memberId;
}
protected Member load() {
InjectorHolder.getInjector().inject(this);
return memberService.getById(memberId);
}
}

Erik.

From the examples I've seen the IDataProvider implementation of the

method brings back (for example) a list of keys from the database.
The model method uses something like a LoadableDetachableModel to
populate
a
model for use by the consumer using the list of keys previously
retrieved.
This seems like a lot of database hits to me. Is this simply because of
the
serialization/model mechanism?
It seems to me that the iterator could/should bring back the data in one
hit
and then after use be detached. Is this common?
Many thanks, Graeme.

Re: Question on PageMap
I am not sure what the default is set to Look at the constructors of DiskPageStore. My end goal is to try and squeeze more performance out of my application. If that is your goal you are on the wrong track. The disk store is a rotating logging based, mostly write-only store. Logging based as new content is written sequentially from start to end of the file, rotated because when the file is full it starts at byte 0 thereby overwriting old pages. It is mostly write-only as only when a user presses the back button data may be read back from the page store. Early removal of data will only mean more disk-head movements making it slower instead of faster. Regards, Erik.

Is there a way I can remove my page from the PageMap when I know I am no longer going to need its values? My end goal is to try and squeeze more performance out of my application. I hope this is understandable... any thoughts? -- Erik van Oosten http://www.day-to-day-stuff.blogspot.com/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Handling exceptions during render
It won't. I think you have to dig deeper into the request rendering.
Perhaps that overriding MarkupContainer#renderAll on all your Panels
that have expected exceptions will help.
But then again, exceptions are intended for controlling the
non-expected. You should not use exceptions for normal page flow. In
other words: just make sure that no exceptions are thrown.

Erik.

Ok, but how would that let me render the rest of the page?

There are more threads about this issue...
In order to catch all runtime exception, you have to override default
RequestCycle (newRequestCycle method) in your application class and
override onRuntimeException method.
Example:
[CODE]
@Override
public RequestCycle newRequestCycle(final Request request, final Response
response) {
return new WebRequestCycle(this, (WebRequest) request, (WebResponse)
response) {
@Override
public Page onRuntimeException(final Page page, final
RuntimeException e) {
//do something
return null;
}
}
}
[/CODE]
