Re: Why you should not override isVisible

Re: Why you should not override isVisible
Sorry Sven, You of course meant to say: /If/ isVisible would no longer be called after detach /then/ it would be possible to do the caching yourself (as you can use detach to clear the cache). /If/ you can cache yourself /then/ Wicket does not need to cache the result of isVisible. Although I think that logic is completely correct, I also think it would be very convenient to remove the burden of caching the visible flag during render from the programmer.

Re: Why you should not override isVisible
Created an issue: http://issues.apache.org/jira/browse/WICKET-2025 Regards, Erik. Erik van Oosten wrote: 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?). I can bang my head against the wall for not having documented the problem more thoroughly back then. Anyways, a call to isVisible /after/ detach has similar problems to a call during detach.

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
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: 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: Quickstart 1.4-rc1 exception
Sorry, I do not understand your suggestion. I am running in a new shell,
there are no environment variable like CP set.
The command I execute is:
mvn archetype:create -DarchetypeGroupId=org.apache.wicket
-DarchetypeArtifactId=wicket-archetype-quickstart
-DarchetypeVersion=1.4-rc1 -DgroupId=nl.grons -DartifactId=homepagebug
The only classpath I see is in the mvn script:
exec $JAVACMD \
$MAVEN_OPTS \
-classpath ${M2_HOME}/boot/classworlds-*.jar \
-Dclassworlds.conf=${M2_HOME}/bin/m2.conf \
-Dmaven.home=${M2_HOME} \
${CLASSWORLDS_LAUNCHER} $QUOTED_ARGS
So how do I remove wicket-velocity from the classpath?
Why is this related to wicket-velocity at all? Isn't this a package from
velocity (not wicket-velocity)?
Regards,
Erik.

Re: Quickstart 1.4-rc1 exception
It appears that my Maven repository (artifactory) is not functional
anymore. Somehow its empty.
I'll switch to central for a moment.
Sorry for the hassle.

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);
}
}
Regards,
Erik.

Hi.
From the examples I've seen the IDataProvider implementation of the
iterator
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. David R Robison wrote: I have been monitoring the size of the pm-null file stored in the Work directory from Tomcat. I assume that it is the serialized version of the PageMap. I have an application where, if I navigate from page A to page B and then back to page A, the pm-null file keeps growing. I understand that I can set the maximum number of pages saved in the PageMap but I am not sure what the default is set to. Also, if I am leaving a page with a form and do not intend to return to that page and submit its values, do I even need it in the PageMap? 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.
Regards,
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;
}
}

Re: Handling exceptions during render
Yeah, I was afraid it would come to that. Sorry, you've apparently done some more research already... Another thing I sometimes do is take the Wicket class and put it in the web-project's classpath but with my changes (e.g. remove a final). All servlet containers will load earlier from the WEB-INF/classes folder then from WEB-INF/lib. Its a huge hack, but it works most of the time. Regards, Erik. aditsu wrote: Well, I'm specifically talking about unexpected runtime exceptions. I don't want those to destroy the whole page. They can kill a component, that's ok, but the rest of the page should work. And yes I want to make sure that no exceptions are thrown, except that's not so simple when you're dealing with a complex site and lots of pages, components and models. If I missed any exceptions, I want those to be handled gracefully rather than redirecting to an error page. renderAll is ONLY called on the page, all other components go through renderComponentTagBody to call renderNext, and both renderComponentTagBody and renderNext are final :( I tried overriding onComponentTagBody and wrapping the super invocation with try/catch, but then the markup gets broken because it doesn't close tags (i.e. advance in the markup stream?) after the exception is thrown in a child component, and I still get an error page :( renderComponent(MarkupStream) is final too, it seems that all doors are closed and locked... -- Erik van Oosten http://www.day-to-day-stuff.blogspot.com/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Issue Type: Improvement
Components: wicket
Affects Versions: 1.3.4, 1.4-M3
Reporter: Steve Swinsburg
The ExternalLink component should either by default have a title field, or
have another constructor that takes the title as a paremeter. Currently this
is only achieved by using AttributeAppender and setting the title attribute
onto the link.
eg current:
ExternalLink emailLink = new ExternalLink(mailToLink,new Model(mailto:; +
emailAddress),new Model(emailAddress));
emailLink.add(new AttributeAppender(title, new Model(emailAddress), ));
I propose the following constructor:
ExternalLink(java.lang.String id, java.lang.String href, java.lang.String
label, java.lang.String title)

Re: no title in ExternalLink
Hehe, that's a nice one too.

Re: generate javascript file together with html page
Sound like what you need is a DynamicWebResource. Regards, Erik.

Re: generate javascript file together with html page
I did not use this thing yet, but I believe that you will have to provide enough information to the DynamicWebResource so that it can generate what ever it needs to generate by itself. In an extreme case that could be simply a reference to the containing page, but that sounds quite dangerous to me. Regards, Erik.

Re: Pages or components... how do u decide?
Of topic but important nevertheless: About the only object you ever want to put in the session IMHO is the logged in user and its credentials. Even if you have a very small site with only one important model you should not put it in the session. There are 2 problems with this approach: - Technically you get problems because access to the session is not thread safe. - Usability suffers because the user can no longer have multiple tabs open in the same site and try out different things. Well, ok, /sometimes/ you want to prevent the latter to keep things simple for the user. A shopping cart is probably the best example. Regards, Erik. Alex Objelean wrote: I also like the approach of pushing every functionality in separate components (Panels), it gives me the flexibility of composing pages with any combination of this components. For instance, if I have Login functionality, I create the LoginPanel and LoginPage. This approach allows me to add other Panels (if needed) to LoginPage. Regarding storing the primary model to the base page, I would suggest using a custom session for storing it. This way you can benefit from strongly typed objects and be able access it anywhere in your application.

Re: Empty PageParametyers when using HybridUrlCodingStrategy
I don't understand. Reading the javadoc InlineFrame should set the src attribute. If that is not the case, try setting the src attribute with something like: myFrame.add(new AttributeModifier(src, new Model(urlFor(MyFrame.class, pageParameters; Regards, Erik. itayh wrote: Hi Erik, You are right, the src AttributeModifier overwrites params values.

I need to decorate all my pages but I don't want to decorate the iframes (no need for headers and footers there).

Re: Empty PageParametyers when using HybridUrlCodingStrategy
That combination is wrong. If you use the IndexedHybridUrlCodingStrategy
the first parameter is called 0. Secondly the AttributeModifier
probably overwrites the generated src attribute.
This should work (not tested):
PageParameters params = new PageParameters();
params.put(0, myUrl);// changed to put, just to be sure
InlineFrame myFrame = new InlineFrame(MyFrame, this.getPageMap(),
MyFrame.class, params);
add(myFrame);
public MyFrame(PageParameters params){
String url = params.getString(0); // changed to getString
doSomething(url);
}
mount(new IndexedHybridUrlCodingStrategy(iframe/MyFrame, MyFrame.class)); //
removed leading /
Good luck!
Erik.

I tried also for the url mounting:
mount(new HybridUrlCodingStrategy(/iframe/MyFrame, MyFrame.class));
In all cases the params inside the constructor of MyFrame class has no
values in them (size = 0)

Re: Form GET doesn't call onSubmit method
Hi Eyal,
Let me translate Igor's reponse (which I agree is somewhat short for the
uninitiated ;) )
Quickstart is the optimum way to start with Wicket. For more info see
http://wicket.apache.org/quickstart.html.
A quickstart is an as small as possible Wicket application that
demonstrates a bug and was created with Quickstart.
Igor's question also indicates he thinks there is a bug. You can file
the bug by creating an issue in Wicket's bug tracking system at:
https://issues.apache.org/jira/browse/WICKET. The quickstart should be
attached to the created issue.
Regards,
Erik.

Issue Type: Bug
Components: wicket
Affects Versions: 1.4-M2

Fix For: 1.3.5, 1.4-M4
Hi,
i tried render the javascript as:
public void renderHead(IHeaderResponse response) {
response.renderJavascriptReference(contextPath + js/test.js);
}
The test.js is in webapp/js/test.js (out of classpath). All works greatly in
Opera but in FF (gecko) is there a problem in wicket-ajax.js (the code is
form trunk version):
836: if (Wicket.Browser.isGecko()) {
837: var href = document.location.href;
838: var lastIndexOf = href.lastIndexOf('/');
839: if (lastIndexOf 0)
840: {
841: url = href.substring(0,lastIndexOf+1) + url;
842:}
843:}
Why is there this fix/workaround? This works only for relative path but for
absolute is this code broken.

Re: Nice urls in markup
Liz,
The href-Element of my Ajax-Fallbacklinks show a pretty URLs now, but the
fallback links don't work anymore, if JavaScript is disabled.
That is the intention, the fallback links only work when havascript is
enabled.
I think you should mount your pages like this:
mount(new HybridUrlCodingStrategy(home/project, ProjectPage.class));
mount(new HybridUrlCodingStrategy(home/team, TeamPage.class));
Regards,
Erik.

The thing I'd like to do is to mount a different, meaningful URLs for each
Ajax-Fallbacklink. This URL should be shown in markup and within the
address line of the browser. And of course, the link should work
afterwards:
ul

I've been wondering, if it is even possible to do that. Could anyone try to

Subject: Re: Nice urls in markup
Use a HybridUrlCodingStrategy to mount your pages. This will make ajax
request link to a similar URL as the page your are mounting (it adds a
number).

Erik.
Liz Huber wrote:
I'm trying to beautify all wicket urls of my application by mounting
the
pages to meaningful paths.
Thereby the urls become pretty in the browser's address line.
But within the rendered markup links and images still have non formated
wicket urls.
So I mounted the images as shared resources and successfully tricked by
overwriting methode onComponentTag():
@Override
protected void onComponentTag(ComponentTag tag)
{
super.onComponentTag(tag);
tag.put(src, urlFor(getImageResourceReference()).toString());
}
The same way I proceeded concerning links: I mounted the referenced
page
and overwrote methode onComponentTag():
@Override
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
if (clazz != null) {
tag.put(href, urlFor(clazz, null)); //where clazz =
Class.forName(getDefaultModelObjectAsString());
} else {
tag.remove(href);
}
}
This works pretty well and the urls in markup look like the mountpaths.
But
one problem is still remaining. I created a list containing ajax
fallback
links. In markup they contain a href attribute, which is probably
used,
when java script is deactivated.
...ul
lia
href=?wicket:interface=:0:panelMiddleNavigation:navMail:0:navMail_item::ILinkListener::
id=navMail__itema onclick=var
wcall=wicketAjaxGet('?wicket:interface=:0:panelMiddleNavigation:navMail:0:navMail_item::IBehaviorListener:0:',null,null,
function() {return Wicket.$('navMail__itema') !=
null;}.bind(this));return
!wcall;spanAjaxLink 1/span/a/li
/ul
ul
lia
href=?wicket:interface=:0:panelMiddleNavigation:navMail:1:navMail_item::ILinkListener::
id=navMail__itemb onclick=var
wcall=wicketAjaxGet('?wicket:interface=:0:panelMiddleNavigation:navMail:1:navMail_item::IBehaviorListener:0:',null,null,
function() {return Wicket.$('navMail__itemb') !=
null;}.bind(this));return
!wcall;spanAjaxLink 2/span/a/li
/ul...
I'd like to formate this url as well but I don't know how. I've already
tried to mount Pages with parameters and to overwrite the href in the
onComponentTag() methode. But it didn't help!
Could you please give me a clue!
Thanks,

Re: isVisible Problem
Overriding isVisible can be quite evil. The problem is that it is called
also in the detach phase. When isVisible depends on the model, your
model is often reloaded!
There are 2 solutions:
- within method isVisible cache the result, clear the cache in the onDetach.
- (recommended) don't override isVisible but do:
@Override void onBeforeRender() {
setVisible(.);
}
@Override boolean callOnBeforeRenderIfNotVisible() {
return true;
}
Regards,
Erik.
Markus Haspl wrote:
hi,
i have a WebPage with a lot of Panels on it. Each Panel overrides the
isVisible() method because not every Panel should be displayed on the page.
The Problem is: the constructor of each Panel (also which aren't visible) is
called and i have a lot of load on the server. So i tried to make a init()
method (add's all components to the panel) wich is only called when
isVisible==true, but then i get the errors that it couldn't find the
components on panelXX.

Re: error handling and redirect (was: how to logout and redirect)
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. m_salman wrote: Thanks for your reply.

Re: Wicket, HTML or XHTML ?
For Wicket the doctype is not needed, so do what you like. Just remember to keep it in XML syntax.

Note, the code above will also require changes in the ajax code. The ajax code
currently only retrieves the first text node for every type of response, with
the escaping from above it should get all text nodes and concatenate them (like
a XPath query would do). Actually, you should *always* get all text nodes as
most XML DOM parsers (if not, all) do not guarantee that they put all
consecutive text in a single text node.
The fix above is not complete, it should also give back another encoding string
(method getEncodingName()).

I have a page that uses AjaxFallbackDefaultDataTable (using
SortableDataProvider ). The markup contains user-define javascript that I
added. When I try to do some action (delete row) with the table, the page
doesn't refresh in IE6 and IE7. I checked the Wicket Ajax Debugger and it
displays:
ERROR: Error while parsing response: Object required
INFO: Invoking post-call handler(s)...
INFO: invoking failure handler(s)...
I also noticed that the user-define javascript that was returned by the ajax
debugger was appended by ^. (See javascript below):
// enable disable button.
function setButtonState() {
var formObj =
eval(document.getElementsByName(contactListForm)[0]^);
var state = anyChecked(formObj);
document.getElementsByName(deleteContactsButton)[0]^.disabled = !state;
document.getElementsByName(newContactGroupButton)[0]^.disabled = !state;
document.getElementsByName(newEventButton)[0]^.disabled
= !state;

When I do setResponsePage(MyHomePage.class) IE tries to show me
my.site.com/./ url and gets 404 response.
Firefox just shows my.site.com without any troubles. I'm using wicket
1.3-beta2 and WicketFilter mapped to /*.
It's being reproduced under tomcat only, jetty works fine. My tomcat version
is 5.5.17.

Components: wicket
Affects Versions: 1.3.2
Environment: Wicket 1.3.2
JBoss 4.0/Jetty 6.1.7

Reporter: Will Hoover

Fix For: 1.3.5

SYNOPSIS:
1) Web application is using the root context (/)
1) form.add(new Button(mybutton));
2) Button is clicked on any WebPage that is NOT MOUNTED
ISSUE:
WebRequestCodingStrategy.encode appends './' to the URL. The page is
redirected to http://www.mysite.com/./; It works fine in Firefox and Opera,
but in IE an HTTP 404 ('.' page is not found) is rendered.
Mounting the home page to something like '/home' solved the problem ('./' is
not appended, but this causes a redirect every time a use hits the page).

We are using AjaxRequestTarget while at the client side we use jquery only and
therefore also have problems with the '^' in the raw stream.
By replacing the AjaxRequestTarget#encode method with the following, you get
proper XML escaping.

Re: Changing components before rendering
There is.
As you noticed you can change any property you like /before/ the render
phase.
Another way to put metadata on components is annotations. This is for
example used for security type of things. You can intercept the creation
and rendering of each component in Wicket (in your application's init
call getSecuritySettings().setAuthorizationStrategy(...)). The strategy
object you pass here can analyze the annotation on the component and
(dis)allow creation, rendering and enabled state (what enabled means is
up to the component). Wicket-auth-roles and wicket-auth-roles-example
are a good showcase.
Regards,
Erik.

Hi,
What I'm trying to do is to change components properties (visible/hidden,
editable/read-only, etc.) depending on some external context (authorization,
model state, etc.), but I don't want to have to change their properties on
events. Instead, I'd like to modularize these kinds of modifications and add
it to components.
I tried to do this with IBehavior implementations, but it didn't work
straight forward, because you can't modify some properties while rendering
the component (wicket throws an exception).
What I did for this to work was to add an IBehavior to the Page, which
iterates over the component tree, modifying what is needed. To be able to
add modifications to components themselves, I created another interface
(IComponentModifier), which must be added as an IBehavior (implementations
must implement both interfaces). This is because that was the only way I've
found to add some sort of metadata to components. The IBehavior
implementation would be 'NoOp' in most cases. The code is as follows:
public interface IComponentModifier {
void modify(Component component);
}
public abstract class AbstractComponentModifier extends AbstractBehavior
implements IComponentModifier {
public abstract void modify(Component component);
}
public class ChildrenModifier extends AbstractBehavior {
final String[] roles;
public ChildrenModifier(String... roles) {
this.roles = Arrays.copyOf(roles, roles.length);
}
@Override
public void beforeRender(Component component) {
super.beforeRender(component);
processChild(component);
}
private void processChild(Component component) {
for (IBehavior b : component.getBehaviors())
if (b instanceof IComponentModifier)
((IComponentModifier) b).modify(component);
if (component instanceof MarkupContainer)
for (Component child : IteratorIterable.get(((MarkupContainer)
component).iterator()))
processChild(child);
}
}
public class HomePage extends WebPage {
String text = blablabla;
private final Component label;
public HomePage(final PageParameters parameters) {
*add(new ChildrenModifier());*
label = new Label(hidden, new PropertyModelString(this,
text)).add(*new RoleBasedModifier(ADMIN)*);
add(new Label(message, If you see this message wicket is properly
configured and running!));
FormHomePage form = new FormHomePage(form, new
CompoundPropertyModelHomePage(this));
form.add(new TextFieldString(text));
form.add(label);
add(form);
}
class RoleBasedModifier extends AbstractComponentModifier {
protected final SetString roles;
public RoleBasedModifier(String... roles) {
this.roles = new HashSetString(Arrays.asList(roles));
}
@Override
public void modify(Component component) {
for (String role : roles)
if (((WebRequest)
getRequest()).getHttpServletRequest().isUserInRole(role))
component.setVisibilityAllowed(true);
component.setVisibilityAllowed(false);
}
}
}
Is there another (better) approach?

Re: Custom PageMap
The data is not serializable and is needed in several pages as a part of one transaction - Not serializable: Well that is a hick up. This of course also means that you can not do clustering. I would put the data directly in the HTTP session, or in your own sub class of Wicket's WebSession. I think the page map is no longer available (though perhaps that depends on the page store you select). - Part of one transaction. Do you really mean like JTA transaction? Or are you talking about a conversation (which was what I assumed). Having multiple requests in one (JTA) transaction is not very common. I guess if this is the case a reference to the transaction is part of your non-serializable data. If you did mean conversation/wizard kind of data, then the earlier advice holds. Good luck, Erik.

Re: ResourceModel vs. getLocalizer
There is a big difference, the model variant will evaluate during the render phase. You can not use localization in the constructor of your component, you can however safely construct a ResourceModel (but not call getObject on it). In general, I would use localizer when you need direct access to a message from code. This should be rare though, most message can be placed with the wicket:message element. Regards, Erik. Timo Rantalaiho wrote: On Mon, 18 Aug 2008, lesterburlap wrote: new ResourceModel(my.resource.key).getObject().toString(); or getLocalizer().getString(my.resource.key, MyComponent.this); Isn't the latter same as Component.getString(my.resource.key); ? And ResourceModel can typically be used directly as the model of the Label displaying the String add(new Label(foo, new ResourceModel(my.resource.key))); I've been using getLocalizer almost everywhere, and only using ResourceModel when I'm trying to get a property string during Component construction (to avoid those getLocalizer warnings). But I'm not really sure if my reasoning is good... I wouldn't think that there is any difference. If you are worried about performance, try profiling the application.

Hi, You can suppress the version number in the URL. Doing so will make the encoder always take the last version of the page (or create a new one when it is not present). More details: http://www.nabble.com/More-on-wicket-url-stratergy-td18212748.html#a18273996 Regards, Erik. pixologe wrote: Martijn Dashorst wrote: mount your page with hybridurlcodingstrategy thanks for pointing this out... i've seen this one before, but somehow completely misunderstood how it is supposed to work :-/ still, it is not exactly what i had in mind, since it attaches a version number to every url and AFAIK having the very same content accessible through different URLs is something our beloved search engine sees as a reason to decrease a page's rating... But as I thought about it, I realized that it is just not possible to save a page state without passing an identifier in the url... this would destroy support for conflictless multiple browser windows within a session. Thus, I will either have to go for one of the mentioned solutions.

Re: Remove underline in OrderByBorder link
I think his problem is how to set add the class attribute. In addition,
he probably want another class for each sort direction.

Thx, I agree.but how do I set the CSS for the link in the border and

void CSS while the Border CSS manages the sort changes, and I am not sure
how to manage the link CSS. The OrderByBorder hieracharchy is:
Border (with CSS modifier)
--link (void CSS modifier)
Which renders as
td class=myCSS(either asc, desc, or normal)
a class=

I haven't found an easy way to get to and manager the link part.
If you have any ideas, let me know.

Re: HybridURLs
what i now want to add is to pass additional state You can not do this with a BookmarkablePageLink. The trick is to create a Link with in the onClick something like: // note the variant that accepts a Class argument does not work: setResponsePage(new Page(), pageParameters) // the redirect will change the URL to whatever is mounted for the linked to page setRedirect(true) Regards, Erik. Uwe Schäfer schreef: Martijn Dashorst schrieb: you have to encode the necessary state yourself into the page parameters. There is no way for Wicket to be able how to serialize the state in the URL in some magic way. kind of misunderstanding here. i dont want or need the additional state bookmarkable. all i want is to link to a stateful page and have some parameters set. like /foo/document/21.wicket-0 this is - in fact - what wicket does internally, when navigating on the page. it is just that i do not see a possibility to create links like that from pagelink or bookmarkablepagelink. just to be sure that i make myself clear (i´m not that fluent in english), i´ll describe the scenario in detail: - i have a list/detail page setup. - the list should link to detail-page using a bookmarkable link. - if this link is triggered from another session or after timeout, it should be possible to show the document according to the given parameters. (all fine till here with bookmarkablelink hybridUrlStrategy only) - what i now want to add is to pass additional state (from the List page) to the detail page, that can safely be lost when using the bookmark from outside the session. think of back to my search or smth. i was thinking this should be possible, because wicket does this already when using a simple link on the detail page, for instance. thanks uwe -- -- Erik van Oosten http://day-to-day-stuff.blogspot.com/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Asynchronous Components
Hi Sebastian, If you intend to use Wicket's default detachable models to get data from those services, they will be called sequentially. So those are out. I see 2 options: - In the panel constructor get the data in parallel threads through standard java 5 constructs (dump all your Callables in a ExecutorService and when that is done call get() on the returned Futures). When you have the data continue as normal. This approach is a bit easier then the next option, but only works with stateless pages (unless you known the data is not going to change soon anyway). - Write your own model (extend LoadableDetachableModel) that in the constructor will start a new thread to get the data (put a Callable in an ExecutorService and store the Future). Method load() should block until the thread is done (simply call get() on the Future). The base class will clear the data upon detach. Unfortunately, there is no onAttach() method that Wicket calls when the model data is needed again. To remedy this, you could call an onAttach() method yourself from onBeforeRender() in the component that uses the model. The onAttach method should do nothing when the data is already there, or a Future is already present (which means the data is already being retrieved). (I assume you have read a book on concurrency. If not you should, for example Java Threads.) Regards, Erik. Sebastian wrote: Hi, I have not yet looked much into Wicket but am quite interested in the project. We have a specific requirement where I could not yet find the right information/documentation for. We need to put multiple components onto a page receiving data through web services. A single web services call takes some time. In our scenario it would be bad to have the different components of a page to request their data sequentially, therefore we'd like to have components retrieve the required data in parallel by firing the web services call concurrenlty. What is the best approach to achieve this (preferable in a generic, reusable fashion). I do not want to use AJAX for this, the whole page needs to be rendered at once on the server side.

Re: Asynchronous Components
O, I forgot, be aware that Wicket does not really tolerate pages that take too long to render. Make sure that the page rendering does not take more then 60 seconds in total.

Re: Why isn't the bookmarkable url kept when appending ?wicket:interface=:n:myPage::ILinkListener:: etc?

I think everyone would agree that keeping the bookmarkable part of the url adds value, so I must ask - is there a technical or otherwise good reason not to include it? As long as the current behaviour is the default for bookmarkable pages, it will degrade the user experience for everyone using it, and it seems this could be easily fixed.. -- Edvin -- Erik van Oosten http://day-to-day-stuff.blogspot.com/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Running a huge wicket site(1m + users)
IMHO whether state at the client helps hugely depends on the amount of pages the user works with. If the user hardly ever leaves that one single page, keeping state on the client will help performance, provided the server does not need to keep a copy of (all) that state. The latter deviates from the main Wicket philosophy as I perceive it, but it is certainly possible in a clean way. (In my current project we do this in a few places *.) If you want to go this way, you'd better have a very Javascript capable person in the team. If your user is constantly requesting quite different pages, the Wicket model is probably a better match (possibly using stateless pages wherever possible). Regards, Erik. * Before you ask: we use JQuery to get content from a URL which maps to a stateless Wicket page that serves HTML fragments. For more simple things (e.g. validate an access code) we use a couple of servlets. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: More on wicket url stratergy
Ok, here is my code. Perhaps the way I (ab)use HybridUrlCodingStrategy
is what made the URLs change.
In the ctor of ChangePasswordPage:
FormPasswordObject form = new FormPasswordObject(form, new
CompoundPropertyModelPasswordObject(passwordObject)) {
protected void onSubmit() {
try {
getSession().authenticateMemberByCredentials(me.getEmail(),
passwordObject.getPassword(), true);
... update password ...
info(getLocalizer().getString(form.info.password.changed, this));
setResponsePage(new AccountPage());
} catch (AuthenticationFailure authenticationFailure) {
error(getLocalizer().getString(form.error.wrongpassword, this));
}
}
};
and in Application#init():
mount(new NonVersionedHybridUrlCodingStrategy(settings/account,
AccountPage.class));
mount(new NonVersionedHybridUrlCodingStrategy(settings/account/password,
ChangePasswordPage.class));
NonVersionedHybridUrlCodingStrategy looks like this:
/**
* Variant of Wicket's HybridUrlCodingStrategy.
* Use this URL coding strategy in the frontend for non versioned pages
* (call setVersioned(false) in the constructor) that have some kind of
* feedback (e.g. a form submit).
*/
private static class NonVersionedHybridUrlCodingStrategy extends
HybridUrlCodingStrategy {
public NonVersionedHybridUrlCodingStrategy(String mountPath, Class?
extends Page pageClass) {
super(mountPath, pageClass);
}
@Override
protected String addPageInfo(String url, PageInfo pageInfo) {
// Do not add the version number as super.addPageInfo would do.
return url;
}
}
Regards,
Erik.

Can you please elaborate.
I have this Link in my List class
Link itemLink = new Link( itemLink, listItem.getModel() ){
@Override

PageParameters parameters = new PageParameters();
parameters.add( ItemId, ((Item)getModelObject()).getId().toString());
ItemPage itemPage = new ItemPage( parameters, ItemListPage.this );
itemPage.setRedirect( true );
setResponsePage( itemPage );
}
};
This will produce url like wicket:interface=:2
In My application class I have tried a number of mounting but without
success. Any more pointers?
I use the reference for the ItemListPage to go back from ItemPage to
ItemListPage plus I use the same background as in the ItemListPage.
If a google spider where to index this it would not be successful so I need
a way to get this to be bookmarkable.

Re: generics
In my current project I have:
10 Forms that use a CompoundPropertymodel and
5 Forms that have no model.
IMHO both Form forms :) should be easy to work with.

Erik.
Eelco Hillenius wrote:
thats my point. you work on fields of one object, true, but it does
not necessarily have to be the form's modelobject unless you use a

};
add(form);
form.add(new TextFieldString(symbol, new
PropertyModelString(this, symbol)));
where [value] and [symbol] are clearly fields on the container that
parents the form. inside onsubmit i can just as easily access the
object directly without it being the model object of the form. now if
we factor out the form into a static inner or a top level class, just
like the link discussion, it becomes valuable to have the model.
Yeah, you're right actually. I realize now that I rarely use Form's
model directly. And I actually do the special stuff in the buttons
anyway.

Re: generics
In my current project we try to do everything by BookmarkablePageLinks. Count: - 1 Link with an abstractreadonlymodel - 14 Links without model - 13 bookmarkablepagelinks without model - 2 ajaxfallbacklinks without model in addition we have 4 many used subclasses of bookmarkablepagelink that do not have a model.
