Wicket and Apache Felix

[Joseph Brunner]

Hello,

I've been trying to port a pre-existing web application built on Wicket 1.3
to run in an OSGi environment.  Specifically, I'm running Apache Servicemix
4.2.0.  I have tried to run the webapp with the Springsource pre-bundled
version of Wicket 1.3.3 and bundling my own version of Wicket 1.3.5.  Both
attempts have failed miserably, I believe due to required versions of
dependencies conflicting with Servicemix versions of those dependencies,
which is causing Servicemix to hang.

Has anybody had success running a webapp using a bundled version of Wicket
1.3.* (not Pax Wicket) in a Servicemix environment?  If so, which versions
of Wicket and Spring jar files were you using?  Any help would be
appreciated.

Thanks,
Joe Brunner

Hey,

I find that quite exciting.

Now that you've done the hard work of fitting a non-relational store 
into a Wicket-based framework, do you think it would be hard to 
substitute other data stores such as Redis, CouchDB, BDB for DB4O?

Repeaters are special in the sense that they take their markup and repeatedly 
use it, thus there is not one "repeater" element in the DOM. To use a repeater 
with Ajax you need to wrap it in e.g. a WebMarkupContainer and then repaint 
that with Ajax.

SV: Removing jsessionid from URl

[Wilhelmsen Tor Iver]

The web container will add that to the first response URL when a session is 
created in case cookies are not supported. What is corny is that this is not 
further maintained (in a non-cookie situation) without the developer explicitly 
calling ServletResponse.encodeURL() for all URLs - the container should 
maintain the responsibility for you.

Search the list.  This has been covered a bajillion times.  This is a
feature of the servlet container, not Wicket.

Hi!

I think you can use interface IUnauthorizedComponentInstantiationListener
and push necessary information message to Session object. On SignInPage -
check the session and render the message.

chrome + wicket ajax + back button = problem?

[Ryan Crumley]

All,

I ran into strange behavior involving wicket ajax updates + chrome + back
button. I am pretty sure the issue is not caused by wicket but I am hoping
the problem might sound familiar to someone and they can point me in the
right direction. The scenario goes like this:

- An ajax request is made that updates the DOM.
- The user navigates to another page by clicking on a link.
- The user uses the browser back button to go back to the original page.

After clicking back Google Chrome shows the page as it was originally
rendered (before the DOM update). All other browsers show the page as it was
when the user left the page (with the DOM update). Besides the possibility
of showing stale data the other problem is that the page state has been
altered by the ajax request and links that were originally rendered may no
longer be valid.

I found a few links where people are having similar issues:

http://www.maintaino.com/nuts-and-bolts/2010/04/08/teaching-chrome-not-to-cache-your-rails-pages/

Possibly related to using jQuery and/or window.onUnload() and "bfcache":

http://stackoverflow.com/questions/158319/cross-browser-onload-event-and-the-back-button
https://developer.mozilla.org/En/Using_Firefox_1.5_caching

In addition to using Wicket 1.4.12 I am also using jQuery 1.4.2 and google
analytics on these pages. I don't think any unload handlers have been added
however my only check was looking at all the attributes on the "window"
object via the inspector.

Has anyone else seen similar behavior? Even better, anyone else have a
solution? You may be seeing errors like this one in your logs:

org.apache.wicket.protocol.http.request.InvalidUrlException:
org.apache.wicket.WicketRuntimeException: component wid1:wid2:1:wid3 not
found on page com.foo.xxx


Thanks!

Re: Using WicketTester to verify table content refreshed by AJAX event

Any thoughts on this?

I remember reading somewhere that using AJAX to refresh a component
generated using "repeater" may cause some problems. Is this what I am
against here with WicketTester? (Keep in mind that the table does get
refreshed correctly in production.)

Default unauthorized access handling

[Mike Dee]

I am using wicket-auth and it gets me just about everything I need. I would
like the default handling of an unauthenticated user.  When a page is
accessed by someone who is not logged in, I'd like them directed to the
login page, BUT I'd like a message to appear stating that their session has
timed out or they need to log in.

The default behavior of AuthenticatedWebApplication redirects the user to
the sign-in page if they are not logged in.  Can that behavior be modified
easily (to pass info to the sign-in page) so the sign-in page could show an
extra message like "for security reasons your session has timed out"?

The handling of an unauthorized user is shown below (taken from
AuthenticatedWebApplication).  I would simply like to override this method,
BUT it is FINAL.  I guess I could just duplicate the
AuthenticatedWebApplication class, modify the onUnauthorizedInstantiation()
method, and inherit from it.  But hoping one of the Wicket-heads out there
has an easier way to do this.

Also, why is the method FINAL?

public final void onUnauthorizedInstantiation(final Component component)
{
// If there is a sign in page class declared, and the 
unauthorized
// component is a page, but it's not the sign in page
if (component instanceof Page)
{
if (!AuthenticatedWebSession.get().isSignedIn())
{
// Redirect to intercept page to let the user 
sign in
throw new 
RestartResponseAtInterceptPageException(getSignInPageClass());
}
else
{
onUnauthorizedPage((Page)component);
}
}
else
{
// The component was not a page, so throw an exception
throw new 
UnauthorizedInstantiationException(component.getClass());
}
}

Preventing warnAboutFormComponentInsideEnclosure log entries

[Ian Marshall]

I make moderate use of the  tag in my Wicket HTML. I
notice now that (in development mode) I get log entries of the form

  21-Sep-2010 11:04:04 org.apache.wicket.markup.html.internal.Enclosure
  warnAboutFormComponentInsideEnclosure
  WARNING: Found a form component RadioChoice/frmForm:rcWebSiteMode inside
an enclosure.
  Form components do not work well inside wicket:enclosure tags, use
EnclosureContainer instead

whereas a while before now I did not.

To prevent such log entries being made without changing my
"logging.properties" file, I change my code as per my example below, using
instances of org.apache.wicket.markup.html.basic.EnclosureContainer instead
of  tags.

Since I am aware of no problem with my  tags, can I just
silence these new log messages, or am I condemned to replace all my
 tags which enclose form components with
EnclosureContainer instances (with all the HTML and Java code changes that
this will require)?

Dynamic Column Datatable - Example

[Shelli Orton]

Hi,

 

I think what I need to do is fairly common.  I have a number of
checkboxes that users can select to determine which columns they want
displayed in a datatable.

 

I've been searching for an example of a dynamic datatable and haven't
been able to find one.  I've seen references to a solution in 2008 mail
archives that suggest it might be implemented in 1.4
(http://www.mail-archive.com/users@wicket.apache.org/msg10528.html).
Can anyone confirm that it has been or not?  In either case, is there an
example that someone can point me to?

 

Thanks in advance!

 

Shelli

Just curious:
why do you want to submit a form without any manually input/changed data?

Automatic submit of form (AjaxFormSubmitBehavior)

[Gast, Thorsten]

Hi,

I have a form with a AjaxFormSubmitBehavior. Is it possible to submit this form 
automatically after the rendering of the page is finished.

Regards

Thorsten

Error on constructor call

[Benedikt Schlegel]

Hy folks,

im trying to set up an DataTable with FilterToolbar but now im stuck. I want
to use the GoAndClearFilter, and that for i have to add an additional column
to the DataTable.

Im not quiet sure, which implementation is the right one for that, but as
far as i dont want to populate any data or something i guess the
FilteredAbstractColumn is the one to go with.

So i added an FilteredAbstractColumn, auto-generated the unimplemented
methods and tried to run it, still without GoAndClearFilter, which wouldve
been the next step.
But i got following exception:

java.lang.ArrayStoreException: de.wicketgarden.table1.Table1Page$1
 at de.wicketgarden.table1.Table1Page.(Table1Page.java:46)
 at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
 ...

Heres line 46 of Table1Page.java:

columnArray[4] = new FilteredAbstractColumn(new
Model("")) {
private static final long serialVersionUID = 1L;
@Override
public void populateItem(Item>
cellItem, String componentId, IModel rowModel) {
// no-op
}
@Override
public Component getFilter(String componentId, FilterForm form)
{
return null;
}
};



Any suggestions on this? Does anyone know what this is caused by?

Palette model changing problem

[Java Programmer]

Hello,
I have a problem with Palette component - I try to retain model
objects which were selected in Pallete, and update the list od choices
same time (in other word you have one set of available choices takes
2, than press some ajax button and get different set of choices, than
takes 3, so you should have 2+3 selected choices, but every time after
updating Pallete I got empty selected list).
Maybe you can look at the code:

private void addKeywordPalette() {
final IChoiceRenderer renderer = new IChoiceRenderer() { /not
important/ };
keywordPallete = new Palette(Keyword.KEYWORDS, new
Model(selectedKeywordCategories), new PropertyModel(this,
"categories"), renderer, 10, true) {
protected Recorder newRecorderComponent() {
final Recorder recorder = super.newRecorderComponent();
recorder.add(new AjaxFormComponentUpdatingBehavior("onchange") {
@Override
protected void onUpdate(AjaxRequestTarget
ajaxRequestTarget) {
// here I save model
selectedKeywordCategories =
(ArrayList) keywordPallete.getModelCollection();
LOG.info("selectedKeywordCategories: " +
selectedKeywordCategories);
}
});
return recorder;
}

};

keywordPallete.setOutputMarkupId(true).setOutputMarkupPlaceholderTag(true);
add(keywordPallete);
}
The button which updates Palette component looks like:

private void addGetKeywordsButton() {
final AjaxButton getKeywordsButton = new
AjaxButton(GET_KEYWORDS_BUTTON) {

@Override
protected void onSubmit(AjaxRequestTarget
ajaxRequestTarget, Form form) {
//this updates available choices which and renders
palette component via ajax
final Set categorySet =
keywordService.someServiceWhichReturnsKeywordAndCategory();
categories = new ArrayList(categorySet);
ajaxRequestTarget.addComponent(keywordPallete);
}
};
getKeywordsButton.add(new Image(IMAGE, ADD_IMAGE));
selectKeywordsForm.add(getKeywordsButton);
}

What could be wrong that new model isn't used (I use log4j and the
selectedKeywordCategories have selected objects, but Palette doesn't
use them)? Is there made a copy of that array, or something?

I am using setDefaultButton to submit the form using enter key. It
seems to be working ok, but I have read on the internet that people
are having problems in some browsers. Does anybody have any
recommendations?

Re: FeedbackPanel does not clean up after displaying error messages using Ajax

[droitbarg]

I made a small mistake:

Where it says 
add(new ButtonsPanel("buttonsPanel", detailPanel, feedbackPanel,
form)); 
it should be:

add(new ButtonsPanel("buttonsPanel", detailPanel, feedbackPanel,
primaryform));

Re: FeedbackPanel does not clean up after displaying error messages using Ajax

[droitbarg]

Alexander: thanks for your quick answer!
I have done as you said but I still get the same problem.

My HomePage.java code is:

public HomePage(final PageParameters parameters) {
getSession().setHomePage(this);

Form form = new Form("primaryform");
FeedbackPanel feedbackPanel = new FeedbackPanel("feedbackPanel");
feedbackPanel.setOutputMarkupPlaceholderTag(true);
form.add(feedbackPanel);

DetailPanel detailPanel = new NewClientPanel("newClientPanel");
form.add(detailPanel);
add(new ButtonsPanel("buttonsPanel", detailPanel, feedbackPanel,
form));
add(form);

headerContributions(); 
}

I still get the error messages but they never go away

What about feedback markup ID ? Is it present on the page ? 
It seems that you forgot to invoke setOutputMarkupPlaceholderTag(true) on
FeedbackPanel instance.

FeedbackPanel does not clean up after displaying error messages using Ajax

[droitbarg]

Hello everyone!

I am experiencing a problem whenever submiting a form using an
AjaxSubmitLink. I have tried using wicket from version 1.4.9 to 1.4.12
If the form fields are properly filled the first time( and validation
succeeds) my AjaxSubmitLink calls onSubmit and everything goes straight.
If any required field is missing the proper error message is displayed in
the feedback panel
But if I got an error message and I fill the required field in a second
round,  the error message keeps on coming.
After the first validation failure I always get calls to
AjaxSubmitLink.onError() even though the fields are properly filled.

Could anybody tell me what am I doing wrong?

Here is my code


In my home page I have the following:

HomePage.xml









newClientPanel.xml






[newclient.title]


[name]




[surname]



[phoneNumber]



[email]








newClientPanel.java

private void addComponents() {
clientForm = new Form("newClient");

clientForm.setModel(new CompoundPropertyModel(client));
clientForm.add(new RequiredTextField("name"));
clientForm.add(new RequiredTextField("surname"));
clientForm.add(new RequiredTextField("phoneNumber"));
clientForm.add(new
RequiredTextField("email").add(EmailAddressValidator.getInstance()));
add(clientForm);
}


buttonsPanel.java


saveLink = new AjaxSubmitLink("save", mainform) {

@Override
protected void onSubmit(AjaxRequestTarget target, Form form)
{
//Saving data here

}

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

}

};
add(saveLink);

 TIA

Re: updating page version after an ajax request

May be you could provide the developer with access to the page history
utilities such that i can update the version of the current page at will or
leave things to work normally if i dont want to break anything.  something
like thisPage.getVersion().increment() ;

ChoiceRender and many property expressions

[Andrea Del Bene]

Hi,

I need to render options in a MultipleSelectList using more then one field from
a POJO. Is possible to use ChoiceRender selecting more then one property (for
example passing it more then one property expression)?  

Thank you, Andrea.
