Hi!
Im writing a mobile web interface using wicket. Since there are mobile
devices with various screen resolutions, I need to maintain separate set
of
htmls (per component class) based on category/resolution. Im able to
define
custom place for htmls (thanks to
http://cwiki.apache.org/WICKET/control-where-html-files-are-loaded-from.html
), but having problem with locating correct file at runtime. Wicket is
invoking locate(Class clazz, String path) of my custom
ResourceStreamLocator
for the 1st time only. Then, I assume, its remembering the file path or
stream and always showing htmls for the 1st requesting device category!
Is
there any way (a hack may be!) to instruct/force wicket to invoke
locate(
)
everytime a request comes?
Below a snippet of my current implementation:
public class MyWebApplication extends WebApplication {
protected void init() {
IResourceSettings resourceSettings =
getResourceSettings();
resourceSettings.setResourceStreamLocator(new
MyResourceLocator());
}
}
public class MyResourceLocator extends ResourceStreamLocator {
public IResourceStream locate(final Class clazz, final String path) {
MySession session = MySession.get();
IResourceStream located =
locateByClassLoader(clazz,
getHtmlPath(path, session.getDevice()));
return located;
}
private String getHtmlPath(String path, PlainDevice d) {
if (category-1) {
return category-1-folder-path +
path.substring(path.lastIndexOf(/) + 1);
} else {
return category-2-folder-path +
path.substring(path.lastIndexOf(/) + 1);
}
}
protected IResourceStream locateByClassLoader(final Class
clazz,
final String path) {
ClassLoader classLoader = null;
if (classLoader == null) {
// use context classloader when no specific classloader is set
// (package resources for instance)
classLoader = Thread.currentThread().getContextClassLoader();
}
if (clazz != null) {
classLoader = clazz.getClassLoader();
}
if (classLoader == null) {
// use Wicket classloader when no specific classloader is set
classLoader = getClass().getClassLoader();
}
logger.debug(path : + path);
// Try loading path using classloader
final URL url = classLoader.getResource(path);
if (url != null) {
return new UrlResourceStream(url);
}
return null;
}
}

ComponentModel
Hi,
Class ComponentModel in version 1.4rc4 is generic but setObject methods
still use Object instead of T.
Is there any reason why setObject methods in ComponentModel and in inner
class WrapModel does not use type T as input parameter?
I recommend to change from
public final void setObject(Object object)
{
throw new RuntimeException(set object call not expected on a
IComponentAssignedModel);
}
to
public final void setObject(T object)
{
throw new RuntimeException(set object call not expected on a
IComponentAssignedModel);
}
and this
protected void setObject(Component component, Object object)
{
}
to
protected void setObject(Component component, T object)
{
}
and this
/**
* @see org.apache.wicket.model.IModel#setObject(java.lang.Object)
*/
public void setObject(Object object)
{
ComponentModel.this.setObject(component, object);
}
to
/**
* @see org.apache.wicket.model.IModel#setObject(java.lang.Object)
*/
public void setObject(T object)
{
ComponentModel.this.setObject(component, object);

Ajax request and lifecycle of model attach/detach
Hi
When I use an AjaxLink and it's onClick event is called, it seems that none
of the components of the page that the AjaxLink is on has its attach/detach
model methods called.
Here is an example (I just made this quickly and roughly in order to
demonstrate the issue):
-
package com.company.web.wicket.pages;
import java.util.List;
import org.apache.wicket.ajax.AjaxRequestTarget;
import org.apache.wicket.ajax.markup.html.AjaxLink;
import org.apache.wicket.markup.html.WebMarkupContainer;
import org.apache.wicket.markup.html.basic.Label;
import org.apache.wicket.markup.html.list.ListItem;
import org.apache.wicket.markup.html.list.ListView;
import org.apache.wicket.model.LoadableDetachableModel;
import org.apache.wicket.spring.injection.annot.SpringBean;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.company.web.dao.AccountManager;
import com.company.web.dao.UsageLogManager;
import com.company.web.domain.UsageLog;
@SuppressWarnings(serial)
public class HibernateTestPage extends ExternalPage
{
private static final Logger logger =
LoggerFactory.getLogger(HibernateTestPage.class);
@SpringBean
protected AccountManager accountManager;
@SpringBean
private UsageLogManager usageLogManager;
@SpringBean
private SessionFactory sessionFactory;
protected class HibernateLoadableDetachableModel extends
LoadableDetachableModel
{
@Override
protected Object load()
{
logger.debug(Loading usageLogs...);
ListUsageLog usageLogs =
usageLogManager.getUsageLogs(accountManager.findById(1));
return usageLogs;
}
}
public HibernateTestPage()
{
final WebMarkupContainer container = new
WebMarkupContainer(container);
final ListView listView = new ListView(logsView,new
HibernateLoadableDetachableModel())
{
@Override
protected void populateItem(ListItem listItem)
{
final UsageLog usageLog = (UsageLog)
listItem.getModelObject();
Session session = sessionFactory.getCurrentSession();
logger.debug(usageLog in populate item is in hibernate
session? + session.contains(usageLog) );
Label ipAddress = new
Label(ipAddress,usageLog.getIpAddress());
listItem.add(ipAddress);
Label outcome = new
Label(outcome,usageLog.getOutcome().toString());
listItem.add(outcome);
Label outcomeMsg = new
Label(outcomeMsg,usageLog.getOutcomeMsg());
listItem.add(outcomeMsg);
AjaxLink checkLink = new AjaxLink(checkHibernateLink)
{
@Override
public void onClick(AjaxRequestTarget target)
{
Session session =
sessionFactory.getCurrentSession();
logger.debug(usageLog in checkLink is in hibernate
session? + session.contains(usageLog) );
}
};
listItem.add(checkLink);
}
};
add(container);
container.add(listView);
}
}
-
The output when the page is first accessed prints:
Loading usageLogs...
usageLog in populate item is in hibernate session? true # For each item
However, When the checkLink is clicked it prints
usageLog in checkLink is in hibernate session? false
The logs show that the ListView's model is not loaded when the checkLink is
clicked.
I always thought that when a page is accessed by a request that all the
components are told to attach their model at the start of the request. This
does not seem to be the case. I have read
all the available request lifecycle documentation I have found but still
have not found why the model is not loaded for the page's components on an
AjaxLink click.
Can anyone explain this behavior and maybe give me a bit more detail how the
request lifecycle and the component model's work together.
If I add target.addComponent(container) in the onClick method of checkLink
the model for the ListView is loaded and populateItem is called again, with
printing true for in hibernate session. But I need to be able to access
the attached instance of the hibernate object in the AjaxLink's onClick
method. What is the best way to achieve this?
Thanks
Problem passing anonym-classes-models to pages
Hi,
I use a lot of anonym-classes-models which a want to pass to Page
instances (no need for be bookmarkable)
class HomePage() {
// some Models here
IModelEntity model = new LoadableDetachableModel();
// some Buttons-eventhandler
public onClick() {
IModelString m = new AbstractReadOnlyModelString() {
public String getObject() {
return hello page.
}
}
setResponsePage( new HelloPage(m) );
}
//
public void detach() {
model.detach();
}
As i discovered now, this seems not to fit conceptually.
1. using anonym model-classes m javac always generates a reference to
to enclosing class-instance, here HomePage
2. during detachment of page HelloPage the model m will ne detached
correctly (clearing transient all objects)
3. after detachment the page HelloPage is going to be serialized,
which the effect that the reference to the page HomePage
is serialized as well, without detaching thier models.
Are there any best-practices related to this issue?
Maybe pushing the HomePage on the page-map-stack forking
setResponsePage?
Thanks

Re: Problem passing anonym-classes-models to pages
Don't pass IModels around, use the model values they represent. Unless
of course, you know what you are doing. For example, if you share a
Model between two pages, it actually becomes two different instances
after being passed on: one in the first page PageA (serialized with
PageA), and one in the response page PageB (serialized with PageB).
When you try to check whether PageA.getModel() == PageB.getModel()
then you'll discover that they are not the same (might be equal, but
not the same instance).
Anonymous IModels should never be passed around.
In our apps we always let each page wrap the domain classes in their
own IModel copy (for example an HibernateModel).

Re: CompoundPropertyModel and Combobox
The code below works just fine for me. Instead of using complex type as a
model object for a drop down I use an instance of IChoiceRenderer to control
what's used for an id and what's displayed as a value.
User user = ;
setModel(new CompoundPropertyModel(user));
add(new DropDownChoice(usrRole, SystemRole.asStringList(), new
IChoiceRenderer() {
@Override
public String getDisplayValue(Object object) {
return Enum.valueOf(SystemRole.class,
object.toString()).getRoleName();
}
@Override
public String getIdValue(Object object, int index) {
if (index == -1) {
return SystemRole.SALESMAN.toString();
}
return SystemRole.asStringList().get(index);
}
}).setRequired(true));
The combo items are populated from Enum values:
public enum SystemRole {
SYS_ADMIN(Administrator systemu),
SERVICEMAN(Serwisant),
NETWORK_ADMIN(Administrator sieci),
SALESMAN(Pracownik punktu),
ANY(Bez roli);
private final String roleName;
SystemRole(String roleName) {
this.roleName = roleName;
}
public String getRoleName() {
return roleName;
}
private static ListString stringList;
public static ListString asStringList() {
if (stringList == null) {
stringList = new ArrayListString();
for (SystemRole sr : values()) {
stringList.add(sr.toString());
}
}
return stringList;
}
}
And this is how model object looks like:
public class User {
private Integer usrId;
private String usrLogin;
private String usrPasswrd;
private String usrEmail;
private String usrMobile;
private String usrLandline;
private String usrFirstName;
private String usrLastName;
private String usrRole;
}
Hope this helps :-)
cheers,
Marcin

Re: Storing css and image files
I don't see the issue that you all seem to be experiencing but I can
offer some advice:
CSS, Javascript, images etc should be stored in the webapp directory
NOT mixed in with the rest of the classes and HTML. Your CSS can then
get at them easily if you are using any background images etc. Martijn
mentioned this and its a valid point, you can then unmount the
directories and let the web server serve them statically rather than
Tomcat serve them which takes up threads.
You can use an IHeaderContributor to add any CSS or Javascript
references into the HTML header:
public class BasePage extends WebPage implements IHeaderContributor {
public void renderHead(IHeaderResponse response) {
response.renderCSSReference(css/jquery.cluetip.css);
response.renderJavascriptReference(javascript/jquery.dimensions.js);
response.renderJavascriptReference(javascript/jquery.hoverIntent.js);
response.renderJavascriptReference(javascript/jquery.cluetip.js);
}
If you need to add any images in your page, use a ContextImage which
is relative to the context always.
I tend to use a BasePage which setups the header and have my other
pages extend BasePage you might find it useful as well.
cheers,
Steve

Great. I think it should work for you.
On a side note, I thought that having the images/css/js etc served
from
webserver is pretty common and would be supported by wicket without
having
to add the names within java code.
If I had to guess ... it is probably just a matter of time. There are
probably a lot of design and Wicket Way considerations the team
iterates
through and prioritizes. I think cases like yours bring some of
these usage
points into clearer focus after-which, maybe they'll get some
traction.
My guess is that these folks are pretty busy and that there are
probably 10s
of 100s of similar requests in the queue - so just need some
time ... or
bodies :)
I understand the reasoning behind using new ResourceReference as it
makes
loading locale specific images very simple. But why should wicket
prepend
classpath etc. -- i'm not clear on that. Can't wicket simply ignore
the
src attribute if ResourceReference is not present and use
whatever was
already in the html template? That way I do not have to specify the
image
name within the java code and the separation between java and html is
clean.
It sounds reasonable to me - but I'm not knee deep in the code
either/yet.

I don't know how exactly flash mp4 players work but the player should be able to request the exact byte offset and length from the server.

Re: Expired sign in link after signing out
add(new BookmarkablePageLink(signin, SigninPage.class));
That is one thing I tried, but it didn't work for me. I am using
org.apache.wicket.authentication.panel.SignInPanel and with the above
bookmarkable link, I get the following exception in onSignInSucceeded:
java.lang.IllegalArgumentException: wrong number of arguments

onSignInSucceeded(SignInPage.java:65)
I'm not able to spot the problem from the 1.3.2 source code:
protected void onSignInSucceeded()
{
// If login has been called because the user was not yet
// logged in, than continue to the original destination,
// otherwise to the Home page
if (!continueToOriginalDestination())
{
setResponsePage(getApplication().getSessionSettings().getPageFactory().newPage(
getApplication().getHomePage(), (PageParameters)null));
}
}
I did verify that getHomePage() is correctly returning my home page class
and my home page constructors look like this:
public Index() {
this(null);
}
public Index(final PageParameters parameters) {
super(parameters);
}
Any idea what I'm doing wrong?
Thanks,

Re: Problem passing anonym-classes-models to pages
Hi Martijn,
Think of the following use-case.
There is reusable PersonSelectionPage which should select one person
from a list.
These page should be usable from some other pages which have entities
which can be assigned a person to.
A IModelPerson will be passed to the PersonSelectionPage,
which invokes later model.setObject(Person) after successfull selection.
The specialized assignment code now is contained in the
setObject(Person) method.
IModelPerson pm = new IModelPerson() {
public void setObject() {
// do something clever here
}
}
setResponsePage( new PersonSelectionPage(pm, getPage()) );
The PersonSelectionPage also gets the return-to-page as parameter, to
be able to go-back
(never got this working with
redirectToInterceptPage+continueToOriginalDestination)
Is such a usage out of the best-practices/idea of wicket?

Don't pass IModels around, use the model values they represent. Unless
of course, you know what you are doing. For example, if you share a
Model between two pages, it actually becomes two different instances
after being passed on: one in the first page PageA (serialized with
PageA), and one in the response page PageB (serialized with PageB).
When you try to check whether PageA.getModel() == PageB.getModel()
then you'll discover that they are not the same (might be equal, but
not the same instance).
Anonymous IModels should never be passed around.
In our apps we always let each page wrap the domain classes in their
own IModel copy (for example an HibernateModel).

As i discovered now, this seems not to fit conceptually.
1. using anonym model-classes m javac always generates a reference to to
enclosing class-instance, here HomePage
2. during detachment of page HelloPage the model m will ne detached
correctly (clearing transient all objects)
3. after detachment the page HelloPage is going to be serialized, which
the effect that the reference to the page HomePage
is serialized as well, without detaching thier models.
Are there any best-practices related to this issue?
Maybe pushing the HomePage on the page-map-stack forking
setResponsePage?

Re: Storing css and image files
@Steve
NOT mixed in with the rest of the classes and HTML.
i totally agree with that.
CSS, Javascript, images etc should be stored in the webapp directory
my point is this may not be the case for all. in a big company i worked
before, the css and continue/reset/submit/go buttons etc are stored in a
central repository and had to be src-ed from there. Noway i could copy and
put them into webapp. Now referencing them in my java code would mean that
any change (say new image version) would have to be done within java instead
of just having to change the template.

You can use an IHeaderContributor to add any CSS or Javascript references

}
If you need to add any images in your page, use a ContextImage which is
relative to the context always.
I tend to use a BasePage which setups the header and have my other pages
extend BasePage you might find it useful as well.

RequestLogger and session invalidation
Hi, I'm using Wicket 1.3.6 and RequestLogger.getLiveSessions to get the current sessions in my web application, but I'm experience strange behaviour when session invalidation occurs. When the user logs out of the application, the session is invalidated. This leads to WebApplication.sessionDestroyed to be called, which removes the session from the RequestLogger.liveSessions Map and everything seems to be fine. But the execution continues and eventually RequestCycle.detach gets called, which leads to RequestLogger.requestTime. And that's where the strangest thing happens, on line 254 of RequestLogger.java the invalidated session is created again and added back to the liveSessions Map. Is this the expected behaviour? Since this ensures that the liveSessions Map includes all sessions, even the invalidated ones. And another thing, are there any downsides in keeping RequestLogger on in production environment? I'm thinking that it might hog a lot of resources, but is that the case? Regards, Taneli Korri
Re: Storing css and image files
CSS could still take care of this if your CSS could handle all the
images, included via the IHeaderContributor and then you don't need to
mix the display with the code.
Or setup some constants that take the main prefix to the common
repository so at least you only need to change it in one spot, not
everywhere the images etc are being used.
cheers,

Re: Storing css and image files
This only refers to component (page) specific resources. Not global
resources for your application. If you want to create reusable
components/pages that you can share between projects, then they need
to be on the classpath. If you have a app specific CSS that you
include from your app specific BasePage, there is no reason not to put
it in src/webapp/style.css (similar for javascript files, e.g. a
minimized jquery.js that is concatenated with your global app specific
js files, to minimize the number of connects to your server)
As with any rule: use that gray matter locked between your ears and
common sense!

If you need to add any images in your page, use a ContextImage which is
relative to the context always.
I tend to use a BasePage which setups the header and have my other pages
extend BasePage you might find it useful as well.

I understand the reasoning behind using new ResourceReference as it makes
loading locale specific images very simple. But why should wicket prepend
classpath etc. -- i'm not clear on that. Can't wicket simply ignore the
src attribute if ResourceReference is not present and use whatever was
already in the html template? That way I do not have to specify the image
name within the java code and the separation between java and html is
clean.
It sounds reasonable to me - but I'm not knee deep in the code either/yet.

Re: Storing css and image files
I went thru the thread to understand the context. I agree with
html/java/properties being together, i do not have issues with that. If I
have a standalone app, I will have no issues putting css /js in the
src/main/webapp.
But its the reusability of js/css/images across several projects is whats
bothering me. I think adding javacode like imageButton.add(new
SimpleAttributeModifier(src, /images/continue.gif)) for each and every
page is superfluous. I can minimize the impact several ways (Constants.IMAGE
path or building a Continue Image button etc), but I still think the Java
code should not need to know about the name of the image and where it is
located (classpath or apache webserver). The imagebutton is just responding
to an event related to the wicket:id, where its srced from is the
responsibility of the template.
Ideally the location where the image is sourced from could be left to
template, while the image file name itself could be generated by Wicket
based on locale.
The clean way in my case is as Steve suggested , to use css to display the
image for button.

There is no sane reason why anyone would put the html, js, css and

corresponding.java file. Your .java file can not function without the
.html file. Your component will fail if the .properties file is not
available. When the js file can't be found your component is useless.
Wicket goes beyond the call of duty to provide developers with the
means to encapsulate your components, bringing Object Oriented design

outside the package folder into a separate directory structure breaks
this encapsulation is definitely not the Wicket Way (tm).

You can use an IHeaderContributor to add any CSS or Javascript

Re: Refreshing a list while using ListDataProvider
Rereading the link
http://cwiki.apache.org/WICKET/reading-from-a-database.html
http://cwiki.apache.org/WICKET/reading-from-a-database.html
clearly says that the objects are created only once, this includes the List
results i guess. But the line --
results = getResultsFromCriteria(criteria);
is kinda misleading.. In this case the results should never be a new
ArrayList object for DataView to work. (If using ListView, the setList must
be used).
For eg, when using Spring's JdbcTemplate.queryForList() it always returns a
new list object. To make DataView work, this is probably what should happen:
List tempResult = getResultsFromCriteria(criteria);
results.clear();
results.addAll(tempResult);
Pls correct me if im wrong...

For now Im still extending myDataProvider from ListDataProvider, but no

One question though -- What is the responsibility scope of the
ListDataProvider / IDataProvider?
Am I correct in assuming the following --
1) only operate on the given List/Data (already manipulated)
2) *should not* contain a Dao, and refresh its own list/data.
Because if (2), then I am seeing an issue -- where do I call the
dao.query() ? In the constructor or in the iterator() ? If I do in the
constructor, its not refreshed for further queries. If I do in the
iterator(), then the size() is queried before the DataView calls the
iterator(), so it always returns 0 records for the first time. And also
calling dao.query() in the iterator() will make it query the whole list for
every pagination, which is probably not a good idea.
I liked the idea of dataprovider encapsulating dao, but not clear where
would I refresh it.

Re: Storing css and image files
The clean way in my case is as Steve suggested , to use css to display the image for button. Thanks for all the inputs. Sorry this has dragged out a bit. In my case, I am not sharing static resources across apps. I'm just looking at the best way for each page in my application to retrieve each of the core, application-wide, application-specific, static resource files (js, css, gif, jpg, etc). I might have common.css, header.css, footer.css. Maybe that falls under keep it with the source -- which works just fine / albeit somewhat limiting. So maybe the point is moot and wicket:link/ is the solution for my case. I think physically dropping files in webapp/**/*.css is just fine. I'm really just suggesting the idea of making a robust, infallible way to refer to them that can be written and included just once (in an abstract BaseLayoutPage) and never talked about again :) ... and was entertaining the idea of using the webapp/ directory for this. The suggested IHeaderContributor solution has a few problems in my case. If a developer adds a page 6 mos from now and mounts it to a new, arbitrary URL, */products/cable/offer* - I'd like the css files to all show up - automatically. Unfortunately, IHeaderContributor will not dynamically refer to the original css/styles.css pages. The paths are just echo'd as entered which means ... the single css isn't found. My other made up example - if Wicket (for whatever reason) decides that 1.5 should default to RESTful URLs, would also break anywhere people were hardcoding link href=css/styles.css ... since the new RESTful URLs wouldn't look in the proper location. On the other hand, wicket:link/ continues to work through all of these changes - with no effort or manual management. My initial posts/examples were around c:url value=/css/styles.css/ when included on base base pages, always works no matter what page the user has navigated to ... no matter how deep or shallow the url is. It creates an ABSOLUTE path that simply prepends the context the app is deployed to (which, is free to change or go to root). For what its worth, I think that provides some amount of value to my app. For my specific case, I think Igor's suggestion of a tag like wicket:context/ hit the nail on the head. I can't tell if the other suggestions here are just workarounds or really trying to address my specific use case. IHeaderContribute (thanks for including) doesn't actually do much more than hardcode a fixed path in the markup. Incidentally, I looked - and man, there are alot of pieces to wicket:link/ :-) Is there an online tutorial for, not just writing components, but implementing a markup component like wicket:link/?

The output when the page is first accessed prints:
Loading usageLogs...
usageLog in populate item is in hibernate session? true # For each item
However, When the checkLink is clicked it prints
usageLog in checkLink is in hibernate session? false
The logs show that the ListView's model is not loaded when the checkLink is
clicked.
I always thought that when a page is accessed by a request that all the
components are told to attach their model at the start of the request. This
does not seem to be the case. I have read
all the available request lifecycle documentation I have found but still
have not found why the model is not loaded for the page's components on an
AjaxLink click.
Can anyone explain this behavior and maybe give me a bit more detail how the
request lifecycle and the component model's work together.
If I add target.addComponent(container) in the onClick method of checkLink
the model for the ListView is loaded and populateItem is called again, with
printing true for in hibernate session. But I need to be able to access
the attached instance of the hibernate object in the AjaxLink's onClick
method. What is the best way to achieve this?

successfully onSubmit of the form I need to open a panel in ModalWindow.
There is no Ajax event to fire which leaves me searching for ways to open
the ModalWindow.
I need to open the ModalWindow only on successful upload of the file.
W hen I say success page, I mean within the onSubmit method on the same
page.
Something like this
Form Form = new Form(FORM_NAME, model)
{
private static final long serialVersionUID = 1L;
@Override
protected void onSubmit()
{
FileUpload upload = uploadField.getFileUpload();
//open ModalWindow
}
}
Thanks

Re: Open a Modal Window within a Panel from a FileUpload form
You could use AjaxButton.
This would give you an onSubmit with AjaxRequestTarget in the signature.

dynamically add additional components
is it possible to modify html at runtime and add new components ? for example I have a panel, html code below. wicket:panel div class=contentTittle label wicket:id=pageTittle / /div div class=pageheader div align=center table style=margin-bottom: 0.5em; tbody tr tdAudit Number:/tdgo tdlabel wicket:id=auditNumber//td /tr tr tdGrantee:/td tdlabel wicket:id=grantee//td /tr /tbody /table /div /div div class=pagedescription pspan wicket:id=pageDescription //p /div /wicket:panel I use this panel in several pages, but for one page I have to add additional informationbetween wicket:id=grantee and wicket:id=pageDescription , so I am wondering If I can I create a new class which extends from this panel and if this new class can add a new component to this html and add the component to hirearchy , something like this ,html below has a third tr tag ? wicket:panel div class=contentTittle label wicket:id=pageTittle / /div div class=pageheader div align=center table style=margin-bottom: 0.5em; tbody tr tdAudit Number:/tdgo tdlabel wicket:id=auditNumber//td /tr tr tdGrantee:/td tdlabel wicket:id=grantee//td /tr tr tdProgram:/td tdlabel wicket:id=program//td /tr /tbody /table /div /div div class=pagedescription pspan wicket:id=pageDescription //p /div /wicket:panel please suggest me if it is possible to do this , I donot want to add the third tr tag and call set visible false for all pages and only for one page set it to true ?
DropDownChoice with Id Value
I'm using a DropDownChoice that looks like this: DropDownChoice component = new DropDownChoice(component, new PropertyModel(task, componentId), new PropertyModel(task, project.components), new ChoiceRenderer(name, id)); The problem is that task.project.components is a ListComponent and task.componentId is an int, so I get an error that says: No get method defined for class: class java.lang.Integer expression: id I know that I can fix the problem by making the DropDownChoice's model a Component instead of an int. However, I would like to avoid that, since that would require reworking the Task class. Is there a way to make this work?

How do I reuse a rendered string, i.e. render once and past in multiple locations, e.g. paging nav at top and bottom?
I am trying to do something that should be easy to do, and may already be
available from the API (I am still usin 1.3.5).
How can one duplicate rendered strings?
In other words, I am trying to render once but copy a number of times for
better performance - e.g., putting a page navigator both at the top and
bottom of the list (the bottom is simply a label generated from copying the
rendered top one) or something more complex such as a calendar.
I tried using IBehavior.onRendered to copy getResponse.toString() for later
reuse, but myComponent.renderComponent() throws IllegalStateException: Page
not found - even though I am adding the component to a panel as instructed
by Component.renderComponent() - any ideas? My code is below.
I also thought of overriding one of the rendering methods to write directly
to the response, but Component.renderXXX() methods are all final - there
has to be a way to do this simply.
Any ideas?

Issue regarding refresh a wicket page portlet in Jetspeed portal
Hello , I have an issue with refreshing the portlet in jetspeed. I will try to explain the issue below I have a navigation in Jetspeed which point to a psml file. This psml file will bring up a wicket portlet. In the wicket portlet, I am having multiple pages. So when we click on the navigation link(psml url), I get to the home page of the wicket portlet. I do some action on the home page(Page A) and then use setResponsePage method of the Component class to redirect to a different page(Page B) Now when I click on the navigation page again, instead of going to the home page(Page A) it goes to the Page B directly. I want that whenever I click on the navigation link (which points to a psml file), it should always go to home page(Page A) and not to any intermediate page (Page B in this case) I think what is happenning here is, whenever I click on the navigation link, the last rendered response is rendered by the portlet. Let me know if more details are needed. Regards, Arun Wagle
OutOfMemory on certain combinations of controls
I ran into an issue where I'm getting an OutOfMemory error using autocomplete textbox functionality. I haven't nailed down the root culprit, but the symptoms seem to occur when I have a page with a border that also has controls, such as a panel or two. On the page, if I pop a modal dialog box (with ajax auto-complete) and type into the auto-complete textbox, after some 15-20 key presses, I'll get the OutOfMemory error. If I remove the reference to the window in the modal dialog box, it doesn't occur. Also, if I use inheritance and a child page instead of a page with border, it doesn't seem to occur. I'm testing this with JDK 1.6_07 and ran it in Tomcat 6.0.14. I used Jconsole to watch the heap. After some 15-20 key presses, each subsequent keypress is increasing the heap memory usage by several megs. I looked at the heap dump in MAT and it's showing me 3 huge byte[]. I just started using this tool. If I'm reading this right, it seems to have a lot of threads eating up the heap. This might be hard to reproduce, so I put together a little demo app that can be downloaded at http://silverlion.com/tmp2/wicket_test.zip. It's an eclipse project I just zipped up. I did all this with wicket 1.3.6, but also went back to 1.3.5 to test that. I get the same results. I wanted to post the question here before I opened an issue in jira to see if anybody experienced this. I tried running this with -Xmx256m -Xms256m and also 512 MB of memory. I still get the error on my dev box running tomcat in eclipse and also building the war and deploying it to tomcat outside a dev env. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

The real question that has been asked time and time again on this list
when such a question is received is this:
WHY? It's premature (and almost certainly unnecessary) optimization.
Doing it needlessly couples multiple components together - reducing
reuse.

Re: How do I reuse a rendered string, i.e. render once and past in multiple locations, e.g. paging nav at top and bottom?
OK, thanks Martjin and Jeremy - I think mentioning performance was a mistake
on my part..let me try again.
I am not trying to couple different components, only to reuse what I know is
never going to change within the same rendering - actually, avoiding the use
of multiple component instances of the same subtype where a single instance
would suffice.
My question is: Is it possible to capture a rendered string for reuse? In
other words, if I have a component subtype that I am currently instantiating
multiple times with exactly the same state (therefore the output is exactly
the same), is it possible to render it once and once only and reuse the
string from that rendering within the same container or page?
At this stage I am only trying to know how to do something instead of why
(optimization or other reason, such as saving markup coding, or some other
reason). I went through the source and searched on forums as well to find
out, but didn't.
My apologies if that question has been answered elsewhere - please let me

Re: How do I reuse a rendered string, i.e. render once and past in multiple locations, e.g. paging nav at top and bottom?
no it is not possible and does not make sense to do so.
imagine you have a panel that renders div id=1div id=2/div/div
not only would you have to rewrite the id of the top tag, but also of
the inner tags. this becomes even more complicated if components
output header contributors, eg javascript, that depends on those ids.
if you are instantiating components with the same state then you
should simply connect them all to the same state via models so the
state is reused and does not present overhead.
makes sense?

WHY? It's premature (and almost certainly unnecessary) optimization.
Doing it needlessly couples multiple components together - reducing
reuse.
As always, we are more than interested in seeing any results of
performance analysis that you have done that says that this will
reduce your page load time by any significant factor.

How can one duplicate rendered strings?
In other words, I am trying to render once but copy a number of times
for
better performance - e.g., putting a page navigator both at the top and
bottom of the list (the bottom is simply a label generated from copying
the
rendered top one) or something more complex such as a calendar.
I tried using IBehavior.onRendered to copy getResponse.toString() for
later
reuse, but myComponent.renderComponent() throws IllegalStateException:
Page
not found - even though I am adding the component to a panel as
instructed
by Component.renderComponent() - any ideas? My code is below.
I also thought of overriding one of the rendering methods to write
directly
to the response, but Component.renderXXX() methods are all final - there
has to be a way to do this simply.
Any ideas?
Thanks!

The containing panel java (groovy) code - 'ppn' is the component we want

render only once
.//ProductPanel

productsContainer.add( products )
ProductsPagingNavigator ppn = new ProductsPagingNavigator(
productsPagerTop, products)
ppn.add( new MakeRenderedStringBehavior())

ppn.renderComponent() //THOWS 'Page not found... exc.
//save the rendering for reuse
CharSequence ppnOut = ppn.getRendered()
//reuse it here
productsContainer.add new Label( productsPagerBottom, ppnOut)
//
//***
The Behavior code attached to ppn above:
.// MakeRenderedStringBehavior
//...
public void onRendered(final Component component)
{
//
// Copy the rendering if this component can store it..
CharSequence output = response.toString();
if ( component instanceof IRenderedString )
((IRenderedString )component ).setRendered( output);
webResponse.write(output);

Re: simple model question
if you chain your models properly its no problem.. imodel ldm=new loadabledetachablemodel(..) imodel prop=new propertymodel(ldm, prop); -igor On Wed, May 27, 2009 at 1:20 PM, bf b...@juno.com wrote: I constructed a Page that uses a LoadableDetachableModel. The LoadableDetachableModel retrieves an object from the Session and displays Panels from a list in the object. The Panels have TextFields which use elements from the List but it puts the object into a PropertyModel in order to access the attributes. My question is whether it is a problem to update the TextField via the PropertyModel or does the PropertyModel have to use a LoadableDetachableModel as well in order to get the object from the Session before doing an update?

Re: OutOfMemory on certain combinations of controls
make sure you dont keep page references across pages. that may be it. -igor On Wed, May 27, 2009 at 1:41 PM, Flavius flav...@silverlion.com wrote: I ran into an issue where I'm getting an OutOfMemory error using autocomplete textbox functionality. I haven't nailed down the root culprit, but the symptoms seem to occur when I have a page with a border that also has controls, such as a panel or two. On the page, if I pop a modal dialog box (with ajax auto-complete) and type into the auto-complete textbox, after some 15-20 key presses, I'll get the OutOfMemory error. If I remove the reference to the window in the modal dialog box, it doesn't occur. Also, if I use inheritance and a child page instead of a page with border, it doesn't seem to occur. I'm testing this with JDK 1.6_07 and ran it in Tomcat 6.0.14. I used Jconsole to watch the heap. After some 15-20 key presses, each subsequent keypress is increasing the heap memory usage by several megs. I looked at the heap dump in MAT and it's showing me 3 huge byte[]. I just started using this tool. If I'm reading this right, it seems to have a lot of threads eating up the heap. This might be hard to reproduce, so I put together a little demo app that can be downloaded at http://silverlion.com/tmp2/wicket_test.zip. It's an eclipse project I just zipped up. I did all this with wicket 1.3.6, but also went back to 1.3.5 to test that. I get the same results. I wanted to post the question here before I opened an issue in jira to see if anybody experienced this. I tried running this with -Xmx256m -Xms256m and also 512 MB of memory. I still get the error on my dev box running tomcat in eclipse and also building the war and deploying it to tomcat outside a dev env. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Hi,
Class ComponentModel in version 1.4rc4 is generic but setObject methods
still use Object instead of T.
Is there any reason why setObject methods in ComponentModel and in inner
class WrapModel does not use type T as input parameter?
I recommend to change from
public final void setObject(Object object)
{
throw new RuntimeException(set object call not expected on a
IComponentAssignedModel);
}
to
public final void setObject(T object)
{
throw new RuntimeException(set object call not expected on a
IComponentAssignedModel);
}
and this
protected void setObject(Component component, Object object)
{
}
to
protected void setObject(Component component, T object)
{
}
and this
/**

public void setObject(Object object)
{
ComponentModel.this.setObject(component, object);

/**

Re: Expired sign in link after signing out
If you're on 1.3.2 can you try upgrading to at least the latest 1.3.X
release (or even better, 1.4-rc4) to see if that doesn't fix it?

That is one thing I tried, but it didn't work for me. I am using

I'm not able to spot the problem from the 1.3.2 source code:
protected void onSignInSucceeded()
{
// If login has been called because the user was not yet
// logged in, than continue to the original destination,
// otherwise to the Home page
if (!continueToOriginalDestination())
{
setResponsePage(getApplication().getSessionSettings().getPageFactory().newPage(
getApplication().getHomePage(), (PageParameters)null));
}
}
I did verify that getHomePage() is correctly returning my home page class
and my home page constructors look like this:
public Index() {
this(null);
}
public Index(final PageParameters parameters) {
super(parameters);
}
Any idea what I'm doing wrong?
Thanks,

Re: RequestLogger and session invalidation
Please open a JIRA so this doesn't get lost. I haven't looked, but it sounds wrong if it truly recreates an invalidated session in some end-of-request logging, even if it doesn't bind the session. Post the link back here. -- Jeremy Thomerson http://www.wickettraining.com On Wed, May 27, 2009 at 8:25 AM, Taneli Korri tko...@gmail.com wrote: Hi, I'm using Wicket 1.3.6 and RequestLogger.getLiveSessions to get the current sessions in my web application, but I'm experience strange behaviour when session invalidation occurs. When the user logs out of the application, the session is invalidated. This leads to WebApplication.sessionDestroyed to be called, which removes the session from the RequestLogger.liveSessions Map and everything seems to be fine. But the execution continues and eventually RequestCycle.detach gets called, which leads to RequestLogger.requestTime. And that's where the strangest thing happens, on line 254 of RequestLogger.java the invalidated session is created again and added back to the liveSessions Map. Is this the expected behaviour? Since this ensures that the liveSessions Map includes all sessions, even the invalidated ones. And another thing, are there any downsides in keeping RequestLogger on in production environment? I'm thinking that it might hog a lot of resources, but is that the case?
