Re: Components do not re-render when page is refreshed...
It is rendered, but the existing page is reused so you do not see the constructor called again. That's what Dan meant when he said, That's how Wicket manages stateful pages: it constructs it once, and subsequent actions (including re-rendering all or part) are handled by the same instance. You could override beforeRender() and/or afterRender() and add logging there if you want to verify that rendering occurs. That said, it's clear that you have some problem because you say that nothing happens when the page is refreshed. So what you expect to happen? What change do you not see?

Re: What does this syntax say?
This is called a generic method, and you're just giving the type
signature of the method. Here's an example from our code.
public static T extends Number ComparableT NumberFieldT
withMinimum(String id, T min) {
NumberFieldT f = new NumberFieldT(id);
f.add(new MinimumValidatorT(min));
return f;
}
Which allows:
NumberFieldInteger adultAge = NumberField.withMinimum(bar, 18);
NumberFieldFloat rating = NumberField.withinRange(foo, 0.0, 5.0);

The ClassW parameter is only needed if you intend to do new W(); or the
like in the method (the Class is then something the compiler can grab hold of
for calling the constructor). For just passing the type parameter to other
generic classes it is not needed. The compiler sees the context (i.e. the
left-hand side of an assignment) and if it cannot determine the type it will
say needs a cast as a warning, but the code will compile since it's all

Re: RFC: Ten things every Wicket programmer must know?
Jeremy, I just threw together the following, which indicates that at least to me Models are worth 3 of your 10 items. 1. Most components have a backing object of some sort. This object is referenced via a Model. Significantly, the type of the component and the model match (e.g. LabelInteger has an IModelInteger). 2. These objects live in the session and are managed in the session by wicket, so that when the component goes out of scope the object is removed from the session by wicket. 3. Because domain objects are often too large to store in the session there is a LoadableDetachableModel that is responsible for loading the object whenever it is needed in a request and then flushing it at the end of the request via detach().

Re: Handling futures
Perhaps a transient Future would work for you after all. If the user navigates away the Page is serialized and the Future is thrown away. If you do put futures in a Map, perhaps in the Session, I'd wrap that in an AbstractReadonlyModelFuture. Then you could use have a MapInteger, SoftReferenceFuture (assuming your key is an Integer) if you're still concerned about memory usage getting out of hand.

After these, I plan to use a javascript timer that polls the status of the request and updates a label (or icon). That ajax behavior would be the one polling the Future. What I can't wrap my head around is this: the ajax behavior can't directly hold a reference to the Future because it can be serialized with the page. On the other hand, if I store the Future in a map somewhere and keep a serializable handle in the behavior, there is a possibility that the user will navigate to another page before get() is called on the Future. To avoid running out of memory, this means that I would need to have a daemon that periodically nulls stale Futures from the map so they can be garbage collected. This kind of operation (submit + polling asynchronous result) seems rather common so I'm sure there's some (easy) way to handle it...

I'm wondering if there is a neat trick I can use involving model nesting or something like that to solve this problem?

this way oninitialize() is safe to override in pages because it will

a later time.
Then I think that's the only actual solution that has positive votes.
Without any further feedback, can we agree to leave constructors as they are,
make onInitialize overridable and do it this way?

ajax refresh of ListItems
I have an html table with a ListView generating the rows. Certain
rows in the middle of the table are initially hidden via
setVisible(false), but then displayed later when an AjaxLink is
clicked. In order to effect this I have had tenclose the table in a
div with wicket:id=tableContainer, and then choose the component to
update in an odd manner.
onClick(AjaxRequestTarget target) {
// for each relevant ListItem
item.setVisible(toggleValue);
// why?
if (item.isVisible())
target.addComponent(item);
else
target.addComponent(tableContainer);
}
The rows will only be made visible if the specific ListItems are added
to the AjaxRequestTarget. Refreshing the entire tableContainer does
not display them, even though they have setVisible(true). Conversely,
to hide them I have to refresh tableContainer, refreshing each
ListItem does not hide them.
While I have this working, after a fair bit of trial error, I am
unsure why my earlier approaches failed: 1. always refreshing the
ListItem will not hide them, 2. always refreshing the tableContainer
will not display them.
Is this related to a bug, or am I missing something about ListViews ajax?

I understood your key point, which is why I said as a side note but my point still remains. Loading a list and then sticking it into Model class is in almost all cases a *bad* idea. So use the Model constructors instead. The factory methods are just there to help remove some verbosity related to generics. Have you tried this yourself? Because it doesn't work. You can only instantiate Model with a Serializable instance, and java.util.List does not implement Serializable. The whole point of the ofList method is to generate serializable lists, and the documentation even says so: This factory method will automatically rebuild a nonserializable list into a serializable one. You're confusing Model.listOf with Model.of. Sorry, yes, it was early and I wasn't paying attention. Hadn't had my Wheaties yet :) Have you looked at the ListModel class? It may help with what you're looking for. Do you have a suggestion for a better method signature for that method?

The memory issues comes into play if the IModel is like Model and the contained object is not transient (it is serialized as part of the page). While Pages are serialized each page is serialized independently so on page reload the IModel from the first page is no longer the same object instance as the IModel from the second page. At deserialization time the page1.model.getObject().equals page2.model.getObject() but page1.model.getObject() != page2.model.getObject(); so any changes to either model are not shared between then. This is not a problem if the model is loadable since the memory of the page it is contained in doesn't matter as the value is loaded from the backend db or some other independent data source like the httpsession, or with wicketApplication. You can see the same effect if you try and share a model between a panel and a ModelWindow that uses a PageCreator Hope this helps, Mike Hi, Can someone explain me why it is a memory issue when an instance of an anonymous IModel class is passed to another page to be shared, but it seems to be no problem when a page reference is passed to another page and is put in an instance field (for example to be used in a button to navigate back to previous page)?

Re: Generic solution for tabindex?
We have created a bad solution. The core problem is ajax. Say you
have five fields: A, B, C, D E. Now you want to insert X Y
between A B. No static numbering system will allow an unknown
number of fields to be inserted in between the existing fields.
On top of that you need to have the boundaries of the numbering ranges
well-defined. Say you have two columns, numbered as follows:
A(10) D(40)
B(20) E(50)
C(30) F(60)
Now let's say you insert a new row (our old friends X Y) after the
first, you want to end up with something like:
A(10) D(40)
X(15) Y(45)
B(20) E(50)
C(30) F(60)
But it is not a simple matter to accomplish this. So here's what we
have, which as I said has problems with corner cases.
For various FormComponents we have subclasses such as the following:
public class TabIndexTextFieldT extends TextFieldT implements TabIndexable {
private ModelInteger tabIndexModel = new ModelInteger(0);
public TabIndexTextField(String id) {
super(id);
add(new AttributeModifier(tabindex, true, tabIndexModel));
}
@Override
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
// call a parent WebMarkupContainer that implements TabIndexed
// and knows how to examine
// ValueMap vMap = c.getMarkupAttributes();
// if (vMap.containsKey(tabindex))
//tabIndex = vMap.getInt(tabindex);
// to set the tabIndexModel's value
}
}
The above is reasonably sound, however the implementation of
TabIndexed needs cleanup and has problems with corner conditions.
I'll post the gist of that logic if you like, but the actual
implementation is spread out (unnecessarily) across a couple of
classes.

Now, in the production environment, the number of rows and columns gets quite large such that we have roughly 25.000 cells to render.

The wiki has a list of some web sites that use Wicket. http://cwiki.apache.org/WICKET/websites-based-on-wicket.html A quick search of IBM shows approx 1,080 articles on Wicket: http://www.google.com/search?q=site:ibm.com+wicket Scott On Thu, Jan 7, 2010 at 4:43 PM, Lester Chua cicowic...@gmail.com wrote: Hi, I am facing a hurdle that need crossing in my final attempt to push Wicket for use in an organization.

BUT, the technology evaluation committee is NOT recommending Wicket because of. of all things. - Wicket's Low Adoption Rate Can I find any numbers to blow this away? My alternative is to accept the finding and work with Struts 2. Which will mean the stack will need to expand to DWR (for security). I REALLY don't want to go there, and am even considering not taking part in this project due to the high risk involved, only 9 months to introduce huge changes to a system that has lots of legacy problems (took about 3 years to build). I think a lot of those years were spent wrestling with the monster that is EJB 1.1. The only way I thought the project can even be on time is to scrap the entire presentation layer (aka Struts) and redo it in Wicket with 1 dedicated developer while the rest of the team work on killing the beast that is EJB 1.1 by refactoring the biz code. Sigh, my choices are stark. It's either to keep the job and plough ahead and probably fail spectacularly 9 months later or go hungry and explain to my wife why we need to spend less on the kid.. It's easy to blame the tech committee but they did help me find wicket by rejecting my initial proposal to build the new system on a (JQuery+JSON+REST) framework, which can be very productive as well, if not as clean as Wicket. Sorry for rambling so much. Is there any way I can demolish the silly low adoption rate argument (omg I still don't believe it can be so lame)?

Re: creating item after form is submitted via ajax
Alternately, you can put an EmptyPanel in as a placeholder until you
have Panel2.
---Java Psuedo-Code---
Panel panel1 = new RandomPanel(panel1);
panel1.add(new EmptyPanel(panel2));
add(panel1);
add(new AjaxButton(button, form){
onSubmit(AjaxRequestTarget target, Form form){
Panel panel2 = new RandomPanel(panel2);
panel1.replace(panel2);
}
};

redirect parameter encoding issue
I believe that I see a but in Wicket 1.3.5. Perhaps it has been fixed
in a subsequent version. Under certain circumstances an http
parameter that contains a slash / ascii 47 results in the following
exception:
*** URL fragment has unmatched key/value pairs, responding with 404. ***
The circumstances under which we've encountered this error are as
follows. We have a page that is both the home page:
@Override
public Class? extends Page getHomePage()
{
return VcomCartDetailPage.class;
}
and is also mounted as a bookmarkable page in Application.init()
mountBookmarkablePage(/Cart, VcomCartDetailPage.class);
Then when an http get is made to the app root this is received by the
home page, which works correctly. However, if you then redirect to a
new instance of the same page:
CartDetailPage redirectTo = new VcomCartDetailPage();
redirectTo.modelChanging();
// put stuff in the Cart -- i.e. in the Session
redirectTo.modelChanged();
// This is to guard against resubmitting legacy page cart additions. We
// redirect to a page mapped version of the base CartDetailPage so
that
// the legacy submitted URL is cleared from the browser history,
allowing
// back/forward button support.
setRedirect(true);
setResponsePage(redirectTo);
Then BookmarkablePageRequestTargetUrlCodingStrategy.encode() is
invoked (comes from mountBookmarkablePage in App.init()), and
ultimately the parameters are written in a REST-style in
AbstractRequestTargetUrlCodingStrategy.appendValue().
private void appendValue(AppendingStringBuffer url, String key,
String value)
{
String escapedValue = urlEncodePathComponent(value);
if(!Strings.isEmpty(escapedValue))
{
if(!url.endsWith(/))
url.append(/);
url.append(key).append(/).append(escapedValue).append(/);
}
}
However, because the path component encoder in WicketURLEncoder
public static final WicketURLEncoder PATH_INSTANCE = new
WicketURLEncoder(2);
Does not encode a slash (ascii 47)
// from WicketURLEncoder's constructor
switch(type)
{
case 1: // '\001'
dontNeedEncoding.set(32);
dontNeedEncoding.set(47);
dontNeedEncoding.set(63);
break;
case 2: // '\002'
dontNeedEncoding.set(38);
dontNeedEncoding.set(61);
dontNeedEncoding.set(43);
break;
}
if one of the parameter values contains a slash we end up with a bad
path. E.g. for the following parameters:
key1 :: value1
key2 :: value2with/slashembedded
key3 :: value3
org.apache.wicket.request.target.coding.AbstractRequestTargetUrlCodingStrategy
URL fragment has unmatched key/value pairs, responding with 404.
Fragment: key1/value1/key2/value2with/slashembedded/key3/value3
Can anyone suggest a work-around? Has this been fixed in any version
past 1.3.5?
Thank you,
Scott

Re: OT: Relational database + Hibenate vs Content Repository (Jackrabbit)
Before you consider a non-rdbms solution you should really think about who might be interested in your data.

How many X per hour, and how does that compare with the same value at this time last week?

The tricky part is controlling the depth of the reference graphs that are saved/restored. DB4O has much more control over such things, such as being able to configure 'activation' depth, and also the option of instrumentation to activate references as required (transparent activation) or even persist automatically based on object changes (transparent persistence).

Alternately, I'm unsure why variation wouldn't work for you, something like:
public EmptyPage(String pageVariation)
{
this.pageVariation = pageVariation;
}
@Override
public String getVariation()
{
return pageVariation;
}
Then you could have html classes such as:
BasePage_home.html
BasePage_index.html
BasePage_something.html
From there you could look at MixedParamUrlCodingStrategy to set up urls such as
www.domain.com/some/path/home

Re: Complicated workflows
Phil, Would an event-centric approach simplify things? I'm thinking that you could then have multiple listeners for a given event and the various listeners would not have to be aware of one another. This might reduce the task/sub-task interactions. Adding errors, or refreshing components could be handled by various listeners as needed. I've gone that route with reasonable luck. Of course I know precious little about your specific application... Cheers, Scott On Tue, Sep 29, 2009 at 2:11 PM, Phil Housley undeconstruc...@gmail.com wrote: Hello list, I'm currently working on some ideas for building apps with fairly complex workflows. My aim is to find a nice pattern/framework for building apps where each unit of work involves many panels, several forms, lots of decisions and so on. In particular I'm aiming at apps where you need to be very confident about exactly what is happening, so very strict control of actions, being careful of multiple renderings of a page each trying to change the server data, and so on. Also, I'm wondering about some options for declarative building of workflows out of existing tasks. My current design involves running from a special page, which maintains a stack of tasks. One type of task is a Workflow, which can be configured to automatically spawn subtasks as required, based on the result of previous tasks. Another type of task is based on a panel, and is able to cause itself to be rendered. The stack processor makes sure that each task is invoked at the right time, that a task can render if it is at the top of the stack, that only the top of the stack can be invoked from a form and so on. This is working ok for some silly demo cases, but there are various issues. For example, any task that is not also a component cannot access dependency injection, or set error messages and so on. I'm not sure how to get around this at the moment, as I don't want to force every task to be a component, when many will likely have no cause to ever be rendered. So, the reason I'm posting is to ask mainly two things: 1) Is this of interest to anyone else? All the code is my own, so I'll open source it if there seems to be some future in it. 2) If so, does anyone have any comments on my current design?

Here's a minor point that tripped me up. I have my WicketFilter mapped to a given path: filter-mapping filter-nameWicketFilter/filter-name url-pattern/evansforlv/*/url-pattern /filter-mapping And then when I start up my local app and browse to localhost:8080/evansforlv I get redirected by Jetty to localhost:8080/evansforlv/ with a trailing /.

Sure enough, once I added some stateful pages, I started seeing exceptions related to the DiskPageStore. I'm a neophyte when it comes to the deep down Wicket internals so I'm not sure what my other options might be. In a post Matej Knopp said, * DiskPageStore*'s purpose is to store serialized pages on disk in order to allow access to previous page versions and also to conserve session memory usage. This leads me to believe that using the sassion for storing this information isn't a preferred approach. What about the App Engine's datastore (an abstration on BigTable)? That seems like it might be too slow to adequately serve this need, but I'm not sure. A thread on Wicket/Terracotta integration ended up with an alternative SecondLevelCacheSessionStore but I'm not sure if that is only usable with Terracotta or if it might might sense in other situations.

Re: How to detect model leakage into session
If you are certain that detach is always called then you must have
references to the underlying model objects. I would look through
every call to IModel#getObject().
One thought is that if you create a final variable and refer to that
variable in an anonymous inner class then you have bound the object to
the component. E.g.
final Foo foo = fooModel.getObject();
add(new Label(id, whatever){public isVisible(){return foo.isPurple();}});
// now foo is bound to the label, and will end up in the session

Hi all,
My problem is as follows: I use LoadableDetachableModels throughout my

attached to a component to prevent models which never get their detach()
method called.
Nonetheless, after hitting two fairly simple pages which list some
database data in my application, I get a 100kb session which is filled with
literal strings from model objects.
I've fired up my (Eclipse) debugger and have stepped through all models
on one of the pages after setting a breakpoint on the pages onDetach()
method. I see all LoadableDetachableModels are detached, so I have no idea
what's causing this.
What would be a good strategy for finding the source of this problem?

Why not just lock the relevant row of the relevant table? Versioning is for optimistic locking, but it sounds to me like you want plain old pessimistic locking.

I have implemented something like this before using two database tables one for locking and one for writing who has the lock on a given object. Of course, that wasn't a web application and it wasn't a client/server application (well unless you consider the database the server, which is kind of what I was doing). I would hold on to the transaction for a row id lock table until the corresponding row that the user was editing was updated this included the user think time as they had to press a button to edit, which created this lock table entry as well as a entry in a lock info table that was committed so that when user b tried to hit edit, it would pull a transaction isolation exception and then go lookup who had the item locked. Okay, so I want to implement this same sort of mechanism for check items; however, because there is a common application-level that everyone connected shares (I will only have one webserver as opposed to a farm), I was thinking that I implement a edit-in-progress table as a data source in the application-layer. Then, when someone clicks the edit button on a selected check item, I use the edit-in-progress table to make sure someone else isn't editing the given item. Is this a typical or at least a good approach to solve such a problem or is there something within Hibernate that I am unaware of that handles this. I have read about the mult-versioning but how would you tell the user BEFORE they start to edit something that someone else has it locked?

Re: JDeveloper - Can I get a show of hands?
Dane, I have used JDev and it is not my preference for a Java IDE. That said, if you're having trouble with it your best resource is posting at forums.oracle.com. As for a PL/SQL IDE, why are you moving away from TOAD, the price ($600 if I remember right...)? The product PL/SQL Developer from All Around Automations is a terrific product for more like $180. I have used it extensively and can vouch for it. http://www.allroundautomations.com/ Alternately, there is a PL/SQL IDE from Oracle called SQL Developer (formerly Project Raptor). It is an entirely usable product and it's free. I use this on my Mac at home because it's just Java. http://www.oracle.com/technology/products/database/sql_developer/files/what_is_sqldev.html I don't see why you would need to use the same IDE for Java PL/SQL.

There are a few reasons for the department-wide IDE mandate. Our manager has just discovered UML (I don't know anything about it, to be honest), and JDeveloper provides UML functionality out of the box, while any of the free Eclipse UML plugins I could find required a mountain of dependencies and don't appear to work as smoothly as the JDev one. Also, we're trying to replace TOAD as our database tool, and JDev looks like it can do that. The third reason is that most of our applications are Oracle ApEx, and JDev has stuff for that too. I'm trying to port my existing apps to JDeveloper, but without much success. The main problems so far are: - How do I import a Wicket project using the Maven standard directory layout? (I am aware of the Maven JDev plugin for JDev 10, but it has issues with JDev 11) - How do I run a Wicket app in JDeveloper using the internal WebLogic server? - Does JDeveloper have some sort of Maven-like functionality for project lifecycle management? I imagine (hope) that most of these questions have easy answers, but I'm just not finding a lot of relevant online documentation/discussion.

Re: How (not) to: IModel and Collections (and generics)
Does AbstractReadOnlyModel accomplish what you're talking about? Scott On Wed, Mar 4, 2009 at 4:50 AM, Johannes Schneider maili...@cedarsoft.com wrote: Hi, the concept of IModel seems to be very obvious. It is simply some kind of reference and offers a getter and a setter. When used with ordinary object, everything works fine. An IModel that contains a String can easily be mapped to a TextField. The text field calls getObject to show the initial value and sets the changed string to the model using setObject on form commit. Everything becomes a little more complicated when collections are affected. The problem is, that it is not obvious what those collections represent. 1) A collection might be read-only (e.g. the possible choices for a selection). 2) But it also might be necessary to add/remove single elements (e.g. privileged users shown within a shuffle list). 3) And sometimes the complete collection is changed (can't find an example here). IModel only supports the *third* method where the complete collection is replaced. (Don't forget that the reference to the collection changes which will lead to several other problems.) I strongly recommend the usage of a wrapping class for that case. But this case is not very common. Maybe someone finds a good example - I can't. For the other two cases it does *not* make any sense to call IModel#setObject. Summary: Nearly in every case when the IModel contains a collection, the setObject method does not make any sense and must not be called. Conclusion: I think we should have created some sort of IModelProvider (contains only the getObject method) and IModel (with both methods). Components that just *read* values from the model, accept the read only interface now. For special cases where a magic component adds/removes elements to a collection, we need some sort of ICollectionModel that offers add and remove methods (but no setter). That interface - of course - will be based upon a collection *without* wildcards...

If the constructor accepts the widened type, you can add all those

List? extends Number n = new ListInteger;
List? extends Number n = new ListDouble;

That is the right choice here. You know that you have a special

I think the syntax doesn't really mean read only, and if the wicket

the way to go.
I'm for the plain old ListT because its simple and explicit...

Different positioning of elements ) and here we could use variation. As far as I'm concerned this is not the right way of handling look and feel. Different css should be used instead and then place position, coloring of the markup in a css. The html file should be the same and the css should handle the layout.

Re: Why you should not override isVisible
Probably our model should cache the result of cart.getTotal() since
that's the expensive bit.
That said, I see value in introducing visibility caching into Wicket
core. Others do not. I make my case, the core developers decide, we
move on. :)

If you want to save the reflection overhead why don't you put a caching
model between your component and the CompoundPropertyModel?
Or access the model of the containing component if this is applicable:
public void CartPanel(IModel cart) {
super(new CompoundPropertyModel(cart));
add(new Label(total) {
public boolean isVisible() {
((Cart)CartPanel.this.getModelObject()).getTotal().isPositive();
}
});

I still don't see the need to introduce visibility caching into Wicket core.

Re: Why you should not override isVisible
We have done exact that -- a lot. Driving isVisible() from the state
of the model is very clean, but the performance is potentially awful.
I have wondered whether this should be the default implementation for
Component.isVisible().
Is IVisitor.beforeRender() an appropriate place in the rendering cycle
to make the determination -- i.e.
public abstract class Visibility extends AbstractBehavior {
@Override
public void beforeRender(Component c) {
c.setVisible(isVisible());
}
public abstract boolean isVisible();
}

that visibility state stays consistent for a given problem. If the
performance actually shows up as a hotspot (don't prematurely optimize!),
you can always do some appropriate caching of the value and still have it
pulled.
Erik van Oosten wrote:
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
having to think about the situation described above, and just avoid it
all together.
Note: I observed this behavior in Wicket 1.3 (1.3.3 I think). If it
works differently now, I would be very glad to withdraw this
recommendation.
Regards,
Erik.

Re: Twenty Six Wicket Tricks
Jonathan, I think that Wicket is missing a solid overview of the below form components, how they differ, how they overlap, and when to use each. Check, Checkbox, CheckGroup, CheckGroupSelector DropDownChoice (there are 3 wiki pages, but I'd like to draw out the overlap with RadioChoice and the role of IChoiceRenderer) Radio, RadioChoice, RadioGroup And of course: IChoiceRenderer. For example, I really don't know whether my above list is missing any components. If such a topic is not in the works for your book, I'll volunteer to put together a first pass at such a wiki page.

Re: Moving from Tapestry to Wicket?
Regarding session state, you really have basic options. State is kept in implementations of IModel. 1. Model is just a holder for an object. If you use it then your object is in your session. 2. LoadableDetachableModel stores an id (or whatever) and retrieves the relevant object from your repository. So you're back to the basic tradeoff: memory vs. i/o.

And don't forget final scopes:
final Thing thing = component.getModelObject();
add(new Label(this, that) {
@Override

For the object thing to be accessible in the anonymous inner class
it had to be declared final. Because the Label's isVisible() method
accesses thing, the Label has a reference to thing and thus thing will
be serialized with the Label.

The use of YUI will be more or less internal to Wicket, so you can continue using jQuery, YUI2 or whatever else you are using. Everything in Wicket (and YUI) is namespaced so there are no conflicts. Of course there is the overhead of including two or more libraries in an application, which don't find desirable. Wicket uses only part of YUI, the compressed minified required YUI javascript is about 20kb big. I would understand the concern if I used dojo or some other behemoth with 200+ kb of compressed javascript. + there's huge number and variety of jQuery plugins for those special occasions. Unfortunately the quality of plugins varies. For actual wicket ajax implementation i prefer to stick with the core thing, and that's where YUI definitely beats jquery. I don't say that there are no plugins for jQuery that covers YUI functionality. Question is how well are those plugins supported and maintained. You are well on the point that the variety of plugins varies. I see it this way: jQuery core is small, very stable and the base for everything else JS-related. jQuery UI is the official project providing the same stability and quality for various high-level UI components (like dialogs) and also low-level components (like dragdrop, sortables). We'll see at least two major releases this year that add more components to the mix. Anything else that isn't covered by core or UI is almost always covered by some third-party plugin. While these plugin can be of bady quality (eg. no documentation/demos), they can still provide a good starting point, so that you don't have to start from scratch. Even if you do a full rewrite, the existing plugin can expose useful information like potential browser-bug-traps. Problem is that the jQuery core doesn't cut it. And rewriting plugins from scratch? Are you serious? This is exactly the reason why I decided to use YUI. The stuff that I need is there, it is supported and maintained. Anyway, as I say, this doesn't make any implication to Wicket users or 3rd party components. The reason why wicket ajax is based on another framework is to get rid of most of the low level browser specific code we have currently so that I wouldn't have to maintain it :) Whatever the framework, I think its a good idea to start with something well supported and tested. Thats why I use Wicket, though I'd like it even more with jQuery as the base framework :-) At this point, I really don't see any advantage that YUI would give me over jQuery. Also it is possible that InMethod grid will be part of Wicket 1.5 extensions which is another point for using YUI. Rewriting the grid with jquery would be a huge pain. -Matej Jörn PS: Comet support is a nice to have, but I think there a way more important things for core than that, eg. annotation-based validation - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: ModalWindow tabindex bug
Confirmed: the 1.3.5 modal.js fixes my problem. Thanks again.

ModalWindow tabindex bug
Wicket 1.3.4
I have noticed that in ie 6 7 the tab order no longer corresponds to
the tabindex order for form fields after a ModalWindow is opened and
then closed. It is not the case that the tabindex attributes have
been modified via dhtml, but rather the tabindex is simply no longer
obeyed.
Has anyone else dealt with this?
A simple example:
public class DemoPage extends WebPage
{
public DemoPage()
{
final ModalWindow popup = new ModalWindow(popup);
popup.setContent(new EmptyPanel(popup.getContentId()));
add(popup);
add(new AjaxLink(popupLink)
{
@Override
public void onClick(AjaxRequestTarget target)
{
popup.show(target);
}
});
}
}
