Re: CVE-2021-23937: Apache Wicket: DNS proxy and possible amplification attack

[Matt Pavlovich]

Thank you for the notice, and the already fixed releases =)

Is there a JIRA or associated PR with the fix? I’m not seeing a specific fix in 
the changelogs for 9.3.0 and 8.12.0.

Thanks,

Re: Pluggable architecture for wicket application

[Matt Pavlovich]

I extensively use Wicket+OSGi. Works great! Modular web applications are 
totally doable. Follow Martin's advice and wire in modules using the 
application hooks described.

I know a Dutch company (or two) that use OSGi, I'm certain that one
uses Wicket + OSGi: educator.eu. The other, luminis.eu, does a lot of
work with OSGi, but might not use it in combination with Wicket. I
only have second hand knowledge about the combination, and it's
probably outdated.

Maybe someone from those companies is listening here and cares to comment.

Hello,

We really need advise from Apache Wicket experts. Please let me know if you
have any ideas how to realize the following:

We are working on Orienteer (http://orienteer.org) - open source Business
Application Platform for rapid development.
Orienteer already has pluggable architecture which allow to
start/stop/restart modules and etc. Every module can bring different
things: new webpages, REST, wicket components and etc. For example:
https://github.com/OrienteerBAP/Orienteer/tree/master/orienteer-pivottable

But there is plans to allow dynamically upload required new module (without
recompiling whole WAR with new module).  To upload person can literally
upload JAR or enter URL with the module or specify Maven's
groupId:artifactId:version.

There is no problem with downloading of module: there is a problem with
runtime running it.  Questions:

1) Is there good way for substitution of your own ClassLoader for more
dynamic management?


Wicket doesn't manage class loaders. The web container (like Tomcat) deals
with this.
The only hook provided by Wicket is org.apache.wicket.protocol.
http.WicketFilter#getClassLoader(). See org.apache.wicket.protocol.http.
ReloadingWicketFilter#reloadingClassLoader.



2) Is there a way for restarting of wicket app without restarting a
web-container?


You may use WebApplication#initApplication() and #internalDestroy(). Also
see what ReloadingWicketFilter does.



3) Related to p.1: any good experience with using this:
https://github.com/kamranzafar/JCL ?


IMO this should work to load extra jars dynamically. I didn't see anything
about unloading though.



4) Any other suggetions how to make dynamically pluggable modules in
wicket?


Some people use OSGi (with PAX). I don't have much experience to be able to
comment.



Thanks,

Ilya

Re: Component level cache

[Matt Pavlovich]

+1 agreed.  Caching the data (models) coming from data providers and/or 
services is the best approach

Hi,

I am not aware of such component.
Usually the caching is done in the service layer, not in the UI.
But if you prefer to do it with Wicket then do it in a Model that caches
the DB results.

Hi,

I was just wondering if there is some component to instead of let the a
given component to render itself, check if there is a cache and display its
rendered markup, thus avoiding unnecessary rendering, this could be useful
for stateless components that need to display some list of categories from
the database etc.

Something like this:

class Header extends Panel{
 add(new ExpensiveCategoryListView());
}

class Home extends Page{
 add(new CachedComponent("headerContainer", Header.class))
}

The CachedComponent would first check if there is an already rendered
Header instance (could check in an in-memory store like, infinispan or
hezelcast)

What do you guys think?

Exceptional upgrade experience 6.14.0 -> 6.17.0

[Matt Pavlovich]

Hi all-

I wanted to take a minute to thank all the Wicket Project contributors— 
committers, users and the community as whole. We just completed a seamless 
upgrade from 6.14.0 to 6.17.0 and had to make *zero* code changes.  This is 
extremely impressive for any software project, and especially notable due to 
the fact that we use all sorts of complex Wicket features, extend components, 
and implement custom extensions in our Integrated Console product.  

Our Wicket feature list includes, but isn’t limited to:
 * Modules
 * Events
 * Modals
 * Ajax everywhere— Input, Fields, Validation
 * Custom Authorization Strategy
 * Sortable Tables
 * Feedback panels
 * Breadcrumb bar
 * Ajax auto-refreshing components
 * .. many more

AND, we support running in Tomcat and Apache Karaf (OSGi runtime).

Great work and thank you!

"Document mode restart from > IE9 Standards to Quirks" - any ideas?

[Matt Steele]

Hi folks - I'm running into a really strange issue on IE9 where an ajax
request from Wicket triggers the browser to render Quirks Mode, which fails
the Ajax request, and renders the page unusable.

The error we see in the F12 console is:
"*HTML1113*: *Document mode restart from IE9 Standards to Quirks*"

This has been discussed a few years ago, but no solution was found:
http://mail-archives.apache.org/mod_mbox/wicket-users/20.mbox/%3ccamomwmrla8pizqfzvtbxxbklp5bpmpygqdh2imhn1cvpzep...@mail.gmail.com%3E

It's unclear why this is happening. We've tried using different DOCTYPES,
have added the X-UA-Compatible  tag and HTTP header, but nothing has
solved the problem. It only seems to affect IE9; I've tested IE8 and IE10
and both seem to work fine.

Has anyone encountered this before? I've found two separate Wicket
applications where we encounter this error, and it's really causing us
problems.

HI,

try giving a model to your RadioGroup:

final RadioGroup group = new
RadioGroup("presentationSingleSelectGroup", new
Model());



Hi All,

My company has just started evaluating Wicket on an app that allows users 
to select and merge multiple PowerPoint presentations.


We’ve hit a bit of a problem though, basically at the moment we have one 
long form containing a number of section panels.


The section panels are either ‘multi select’ (a Panel containing a 
CheckGroup that contains Check objects representing the PowerPoint 
presentations in that section) or ‘single select’ (a Panel containing a 
RadioGroup that contains Radio objects).


The problem happens when a validation failure occurs. Basically the 
checkboxes that the user selected prior to the validation failure are 
remembered and repopulated when the user is bounced back to the page but 
the radio buttons that the user selected aren’t remembered.


Any help would be gratefully received, I’ve snipped out what I think are 
the relevant bits of code below...


Thanks

RE: Problem DatePicker, ModalWindow and IE8

[Matt]

Hi Chris,

I have already added a form around my modal window. It resolved some other
issues i had at the begining, but not the "i can't use the close button nor
the change month ones".

I'll have a quick look at your framework if it can help me ... .

Thx ^^

Problem DatePicker, ModalWindow and IE8

[Matt]

Hi everybody,

I've got some issue about the DatePicker.

I'm using Wicket 1.4.17 with wicket extension 1.4.17 as well.

I'v got a modal window, with a form and inside a datetextfield with a
datepicker. Everything is working fine with firefox but not with IE8.

In fact, i can display the calendar when i click on the calendar icon, i can
select a day (which closes the datepicker), but i can't close it with the
close button nor change the current month displayed ... . 

When i put my mouse over one of those buttons (close or change month), i
don't have the "pointer" cursor and when i click it does nothing.

I don't have any javascript error neither.

I tried the datepicker on IE8 but not in a modal window, and it's working.

The only thing that succeded, is that a changed the css attribute "position"
of the close button (set to "relative"), and then i can click the button but
the style is broken and i the the text "Close" above the image in backround
(tried to fix the style then but it's a pain in the ass).

Here is some of my code : 

/
  
  /

Panel added inside the modal : 

/
  
 ...
..

 Wicket message
  
/

Java code is "classical", may be not useful (as html may be lol).

I try hard to fix this but nothing is really working. Maybe it comes from
the way i'm doing it but i can't figure out where ... .

If somebody has an idea, or had and fixed this issue in the past 

Thanks ^^

Detecting when a session is destroyed

[Matt Schmidt]

I am trying to override WebApplication.sessionDestroyed() to perform an
action any time a user's session is terminated, either by manually logging
out, session expiring, or closing the browser. But unfortunately
sessionDestroyed() doesn't seem to get called when the browser is closed. Is
there any way to do this?

Specifically I need to "unlock" all items the user has left "locked" when
their session is terminated.

Thanks!

Re: Manually Rendering a DataGridView

[Matt Schmidt]

I already have a WiQuery plugin/behavior that does basically the same thing.
It renders the table's HTML to the page, then jQuery has to parse through it
and put it in the DOM to initialize. It gets awfully slow with a lot of
data. That's why I'm trying to not render the table to the HTML at all, and
initialize with a JavaScript array that puts the data directly in the DOM.

Re: Manually Rendering a DataGridView

[Matt Schmidt]

Gotcha. Is there a way to do this without adding the DGV to the page? In my
case, I just want to add an empty  tag and pass the "would-be"
rendered HTML of the DGV to a jQuery function that populates the table.

Specifically, I am trying to dynamically instantiate a jQuery DataTables
using the "JavaScript array" method (
http://datatables.net/examples/data_sources/js_array.html).

Re: Manually Rendering a DataGridView

[Matt Schmidt]

So after calling tableParser.parse(myDataGridView), how do I get the the
char sequence? Or iterate over each row to get the char sequence for each
cell? I don't see any public methods for that.

Manually Rendering a DataGridView

[Matt Schmidt]

Is there any way to access the HTML of each cell that would be rendered in a
DataGridView without adding it to the page and actually rendering it?

Ultimately, I am trying to add all of the inner HTML of the cells of the
DataGridView to a JavaScript array.

Not sure if this is a typo in your example, but wouldn't this mean that (the 
real, non-proxied) userEJB.loadUser is invoked when the model is constructed? 
Perhaps this syntax is correct:

model(fromService(userEJB).loadUser(42));

Re: A safer way to build PropertyModels

[Matt Brictson]

This looks fantastic. Can you think of an elegant way to use similar syntactic 
sugar to create LoadableDetachableModels as well?

For example:

// This would return a PropertyModel
model(from(myBean).getChild().getName());

// This a LoadableDetachableModel
loadedModel(from(myService).listUsers());

// Which is more concise than
new LoadableDetachableModel> {
  protected List load() {
myService.listUsers();
  }
}

Hmm. I would expect that your LoginPage would see changes reflected when you

Re: Resource auto-reload with the Quickstart project

[Matt Brictson]

FWIW I tried 1.5-SNAPSHOT and the HTML resource reloading seems to work fine. 
Here's what I did:

1. Generated a quickstart[1] using 1.5-SNAPSHOT using the "-U" maven option to 
ensure the very latest snapshot was downloaded.
2. Pasted in the resource polling code into WicketApplication#init[2].
3. Ran mvn jetty:run.
4. While jetty was running, I edited Home.html: I changed "Congratulations" to 
"Testing".
5. Hit refresh in my browser and the change showed up.

Re: Resource auto-reload with the Quickstart project

[Matt Brictson]

Yes, it is possible configure the jetty plugin to completely redeploy the 
webapp when it detects a class file has changed, but this isn't quite the same 
as what the Eclipse IDE and JRebel do. JRebel's site says: "instantly see any 
code change made to an app *without* redeploying."

In my experience jetty's redeploy leads to memory being exhausted after the 4th 
or 5th redeploy. This is not jetty's fault, but simply because it is 
notoriously difficult to completely eliminate classloader leaks when building 
webapps.

YMMV.

Re: Resource auto-reload with the Quickstart project

[Matt Brictson]

Just to clarify, the resource polling should allow you to see HTML changes (but 
note Martin's comment about this potentially being broken in 1.5RC1). It does 
not affect Java reloading.

For Java changes I believe this is not possible without an IDE or perhaps a 
commercial product like JRebel[1]. For Eclipse, the way I've seen it done is to 
create a class like the Start.java that comes with the quickstart, right click 
on that class, and choose Debug. This will launch a Jetty container inside 
Eclipse's debugger, which gives you auto-reloading of Java files.

Re: Resource auto-reload with the Quickstart project

[Matt Brictson]

The way I've always done it (and this works just fine outside of Eclipse as 
well), is to enable resource polling in Wicket for the directory that contains 
the HTML files.

In the init() method of your WebApplication subclass (in the quickstart this is 
called WicketApplication.java) do something like this:

getResourceSettings().setResourcePollFrequency(Duration.ONE_SECOND);
String htmlDir = getServletContext().getRealPath("/");
if(htmlDir != null && !htmlDir.endsWith("/"))
{
htmlDir += "/";
} 
getResourceSettings().addResourceFolder(htmlDir + "../java");
getResourceSettings().addResourceFolder(htmlDir + "../resources");

You can find this code and some other best practices in my company's source 
repo here:

<http://opensource.55minutes.com/svn/java/trunk/fiftyfive-wicket/fiftyfive-wicket-core/src/main/java/fiftyfive/wicket/FoundationApplication.java>

wicketstuff.org/maven is down - trying to get wicketstuff-merged-resources

[Matt Brictson]

Hello list,

I am trying to download wicketstuff-merged-resources-3.0.jar, which until 
recently was available in the wicketstuff.org maven repository here:

<http://wicketstuff.org/maven/repository/org/wicketstuff/wicketstuff-merged-resources/3.0/wicketstuff-merged-resources-3.0.jar>

Is this a temporary glitch, or has this repository been shut down?

I've also tried maven central and oss.sonatype.org, and while these 
repositories do have other wicketstuff artifacts, they do not have 
wicketstuff-merged-resources-3.0.

Is there a reliable maven repo for wicketstuff-merged-resources?

Thanks.

Re: RadioGroup nulled out during form submit in IE

[Matt Schmidt]

After further investigation, my problem is with the
AjaxFormChoiceComponentUpdatingBehavior. After adding the radio group to the
target in the behavior's onUpdate(), it works.

I have my radio's styled with some fancy jQuery button looks, so I was
unable to see that the actual radio remained unselected after clicking it
when using the Ajax behavior. But adding the group to the target fixes that.

myRadioGroup.add(new AjaxFormChoiceComponentUpdatingBehavior()
{
@Override
protected void onUpdate(AjaxRequestTarget target)
{
target.addComponent(myRadioGroup);
//whatever else
}
});

Is this necessary or is this just working by coincidence?

On a side note, the javadoc for AjaxFormChoiceComponentUpdatingBehavior
says: (wicket 1.4.16)

> In order to be supported by this behavior the group components must output
> children with markup id in format of 'groupId-childId'


Does this just mean this, or something more? It seems to work even if the
structure is not formatted this way

RadioGroup nulled out during form submit in IE

[Matt Schmidt]

I have a form that is working correctly in FireFox but not IE. This puzzled
is quite puzzling to me since it is server side functionality.

Here's a much simplified version of what I've got:



   
   
   
   
   




   
   Radio 1
   
   Radio 2
   
   Radio 3


The RadioGroup's also have an AjaxFormChoiceComponentUpdatingBehavior on it,
and the submit button is an IndicatingAjaxButton.

When I submit the form in FF, everything works fine. When I submit it in IE,
my form's model object has null values for each of the
"myRadioGroupComponent" properties. I stepped through the code and found
that convertedInput is getting set to null during the form's validate(),
because the radio group's value is not in the request
(FormComponent.getInputAsArray()). So it seems to me that IE is not
submitting the form correctly, or that I have invalid HTML that I cannot
identify.

I'm pretty stumped on this one. I can show some of my java if needed, but
the problem doesn't seem to be on that end to me. Any help is appreciated!

Thanks,
Matt

Fate of CompressedResourceReference in Wicket 1.5?

[Matt Brictson]

Hi,

CompressedResourceReference in trunk is basically empty and has the comment 
"TODO NG". A quick search through the source leads me to believe that 
IResourceSettings#getDisableGZipCompression() is also unused.

In other words, gzipping of resources is not implemented in Wicket 1.5.

Are there plans to do so? Part of me thinks that maybe this feature should be 
dropped, as compression makes more sense to handle at the servlet container or 
web server layer (e.g. mod_deflate).

Thoughts?

Are you sure? In Wicket 1.5-rc2 and well as in trunk, 
MarkupContainer#add(Component...) is not final. To clarify: in order to mimic 
the transparent resolver feature, you need to override add(Component...) on 
BasePage, not on the body WebMarkupContainer.

Right. You will need this in your HTML:




If you decide to take Martin's IMarkupFilter approach can you post your share

Re: body tag contributions with wicket 1.5 (Dojo needs it)

[Matt Brictson]

Since isTransparentResolver() is going away in 1.5, the trick that I found is 
to create a normal WebMarkupContainer for the  element, then override 
add(Component...) of the page to mimic the transparent resolver feature.

Your pages can then contribute to the  element by adding 
AttributeModifier, etc. to the WebMarkupContainer.

See:
<https://cwiki.apache.org/WICKET/migration-to-wicket-15.html#MigrationtoWicket1.5-MarkupContainer.isTransparentResolver%2528%2529removed>

Here's an example:

public abstract class BasePage extends WebPage
{
private WebMarkupContainer _body;

public BasePage(PageParameters params)
{
super(params);

// Allow subclasses to register CSS classes on the body tag
WebMarkupContainer body = new WebMarkupContainer("body");
body.setOutputMarkupId(true);
add(body);

// From now on add() will add to _body instead of page
this._body = body;
}

/**
 * Return a component that represents the {@code } of the page.
 * Use this to add CSS classes or set the markup ID for styling purposes.
 */
public WebMarkupContainer getBody()
{
return _body;
}

/**
 * When subclasses of BasePage add components to the page, in reality
 * they need to be added as children of the {@code } container.
 * This implementation ensures the page hierarchy is correctly enforced.
 * 
 * @return {@code this} to allow chaining
 */
@Override
public BasePage add(Component... childs)
{
for(Component c : childs)
{
// Wicket automatically translates  into an
// HtmlHeaderContainer and adds it to the page. Make sure this
// is registered as a direct child of the page itself, not the
// body.
if(null == _body || c instanceof HtmlHeaderContainer)
{
super.add(c);
}
// Everything else goes into the .
else
{
_body.add(c);
}
}
return this;

AjaxLazyLoadPanel question

[Matt Schmidt]

I currently have a DataGridView loaded inside of an AjaxLazyLoadPanel,
including the service call to get the data.

myLazyLoadPanel = new AjaxLazyLoadPanel("id", new CollectionModel()) {
public Component getLazyLoadComponent(String markupId) {
if(getDefaultModelObject() == null) {
setDefaultModelObject(myPojoService.readAll());
}
return new MyDataGridView(markupId, getDefaultModel()); //ignoring
casting for simplicity
}
}

That works great for loading the page before the service call is complete.

But now I need to add a DropDownChoice to change the collection in the data
grid via Ajax after the page is loaded. Is there anyway to get the
DataGridView to be replaced with an Ajax indicator (like on page load)
during an Ajax "onchange" event for the DropDownChoice? I've added an Ajax
indicator to the DropDownChoice, but I would like the same behavior I get on
page load for the AjaxLazyLoadPanel.

This is what I have for the drop down for starters:

myDropDownChoice.add(new AjaxFormComponentUpdateBehavior("onchange") {
protected void onUpdate(AjaxRequestTarget target) {
if(myDropDownChoice.getModelObject().equals(foo)) {
myLazyLoadPanel.setDefaultModelObject(myPojoService.readFoo());
}
//check other selections
   target.addComponent(myLazyLoadPanel);
}
}

I may be looking at this entirely wrong... Any suggestions?

Rerender a Page with Ajax from Abstract Page

[Matt Schmidt]

I am trying to rerender an entire page via ajax from an abstract page.

I have the follow page hierarchy:

abstract class AbstractPage extends WebPage
* dropdown to change an existing session variable
class MyPage1 extends AbstractPage
* component that depends on the value of the session variable
class MyPage2 extends AbstractPage
* another component that depends on the value of the session variable

When the dropdown changes, I want the current page to rerender via ajax, so
I added this in the ajax behavior:

target.addComponent(AbstractPage.this); //also tried
target.addComponent(target.getPage());

But this appears to cause the page to postback and the url changes to use
the page map (?wicket:interface=:4). If I change it and add just the
dropdown to the target, the Ajax request works as expected, but of course
the component in the implementation page (MyPage1) is not rerendered.

Any suggestions?

Modify Attribute on DataView HTML Element

[Matt Schmidt]

I'm trying to modify an attribute on the HTML element that goes with my
DataView:

HTML

   


JAVA
new DataView("dataview", dataProvider) {
   protected void populateItem(Item item) {
  item.add(new Label("myLabel", item.getModelObject().getValue()));
   }
   protected void onComponentTag(ComponentTag tag) {
  super.onComponentTag(tag);
  tag.put("id", "dynamicValue");
   }
}

I thought this would do it, but I never even hit DataView.onComponentTag().
Any other suggestions?

Re: Updating model object on AjaxFallbackDefaultDataTable page change

[Matt Schmidt]

Are you suggesting to override
AjaxPagingNavigator.newPagingNavigationIncrementLink() and
AjaxPagingNavigator.newPagingNavigationLink() and implement our own
navigation links similar to AjaxPagingNavigationIncrementLink and
AjaxPagingNavigationLink that do the same thing except extends
SubmitLink rather than Link?

Am I making that harder than it needs to be? It may help a lot if you
have a code sample for something like this.

Re: Updating model object on AjaxFallbackDefaultDataTable page change

[Matt Schmidt]

Yes that works for the first page - only on that page are the javascript
behaviors rendered.

Basically, we are looking for a way to NOT do an ajax request every time we
check a box - The model object of the check group should be updated when we

a) click the submit button or
b) change the page of the datatable.

What are we missing here?

Updating model object on AjaxFallbackDefaultDataTable page change

[Matt Schmidt]

I have a CheckGroup that contains an AjaxFallbackDefaultDataTable that has a
column containing a Check. As long as I click my submit button while on the
first page of the DataTable, the model object of the CheckGroup is updated
as expected with the items I had checked. However, if I check some
checkboxes and then go to page 2 of the DataTable, the CheckGroup's model
object is not updated and I lose everything I checked on page 1.

The DataTable class has an "onPageChanged()" event, but it appears that it
is called after the page is actually changed.

My other thought was to add an AjaxFormComponentUpdatingBehavior to the
Check, but Check is not a FormComponent.

Any thoughts?

Thanks,
Matt

Re: Lazy load exception with LoadableDetachableModel

[Matt Schmidt]

Ok after further review, my problem was because I was getting this model
from a DataProvider where I was feeding the DataProvider a List AFTER
retrieving from the persistence layer, instead of doing it IN the
DataProvider. Thanks for the help!

Lazy load exception with LoadableDetachableModel

[Matt Schmidt]

I am using LoadableDetachableModel's to load my persisted objects from the
database, but I am still getting a lazy load exception when accessing a
property that is a Set.

For example: take persistent POJO Product that has this property, where
ProductType is another persistent POJO:

private Set productTypes;


I get the lazy load when trying to access this property from the LDM:

Collection x = ((Product) model.getObject()).getProductTypes();

for(ProductType pt : x) { //lazy load here

.


What am I missing?

Thanks,
Matt

I had read that blog entry several times before but the significance of that

Image auto-resize in browser

The images rendered by my page don't auto-resize (very large image) in

How to compile a component for both Wicket 1.3 and 1.4?

[Matt Brictson]

Hello,

I am writing a Wicket component that I would like to use in two different 
Wicket applications. One application is using Wicket 1.4.3, and the other is a 
legacy application using Wicket 1.3.6. Unfortunately upgrading this legacy app 
to 1.4 is not an option.

I'm using maven for my build process. Right now I am considering the following 
approach:

1. Set up a multi-module maven project.

2. Create a "common" module that contains all the code that will safely execute 
in both Wicket 1.3 and Wicket 1.4.

3. Create a "wicket13" module that contains the 1.3-specific code.

4. Create a "wicket14" module that contains the 1.4-specific code.

That sounds like a lot of trouble. Can anyone think of a simpler solution, 
perhaps using maven build profiles? Or am I approaching this completely wrong?

Re: Tree collapse very slow on firefox 3 for nodes with large # of children - Quickstart attached

[Matt Shannon]

Just looking at the firebug profiler, the removeNodes method from tree.js is
the function that is taking way too long to complete.  Checking the DOM, it
looks like all nodes in tree regardless of position have their parent node
set as the wicket panel surrounding the tree.

I would have thought ideally that the various branches of the tree have
their parents referring to the true tree node parent rather than a single
common parent. This would allow collapse functions to simply remove all
nodes of the particular element concerned.

I guess it may be worthwhile experimenting with the following function to
see if it can be optimized with limited interference.

Wicket.Tree.removeNodes = function(prefix, nodeList) {
var problem = false;
for (var i = 0; i < nodeList.length; i++) {
var e = document.getElementById(prefix + nodeList[i]);
if (e != null) {
e.parentNode.removeChild(e);
} else {
// while developing alert a warning
problem = true;
Wicket.Log.error("Can't find node with id " + prefix +
nodeList[i] + ". This shouldn't happen - possible bug in tree?");
}
}
if (problem == true) {
Wicket.Tree.askForReload();
}
}

thanks

Matt.

Truth. You should really reconsider throwing DisplayTag into this. Without
going into paragraphs ans paragraphs of explanatory detail, Wicket just
doesn't work like that. I'm not saying it couldn't be done if you were
enough of a masochist, but the real question would be why?

While not nearly as bad in terms of integration, you may want to rethink
Acegi as well. Perhaps it has changed since the last project I used it on,
but at the time I hated it. Wicket has some nice hooks for adding your own
authorization/authentication schemes and there's a wicket-security project
if you want a pre-built infrastructure.

Re: Automatically adding a parameter to every link?

[Matt Welch]

I'm not worried about the multiple window thing. FWIW I believe that value is
set to true by default anyway. I'm just wondering if there's a way to add a
parameter to each link on page to ensure that the next page stays in the
same context. 

For instance, when I was trying to solve an unrelated problem, the servlet
filter I was working with tied itself directly into the response.encodeUrl()
method so that each call to that method would also use the filter's specific
instructions as well. 

I was hoping that there might be something similar for links in Wicket where
every link, no matter how it's generated (except manually in HTML, of
course) would be handled by a particular method that I could put a hook into
to make sure my context specific request parameter got added.

Re: Tools for Managing a Wicket Project

[Matt Welch]

Tools that our team is using (after some trial and error):

IDE - Eclipse/IDEA
Source Control - SVN
Build - Maven
Local Network Maven Repo - Nexus (after a year trying different ones)
Build Server  - TeamCity, which absolutely rocks (We actually purchased and
used Bamboo for 9 months. I can't believe it comes from the same company as
JIRA. Bamboo was terrible.)
Story Mgmt/Defects - Rally (hosted commercial app for agile projects; not
bad, but not fantastic either)
Code Review - Code Collaborator (again not bad and I'd rather have it than
nothing at all, but could be better)


Our QA team has used various testing tools from expensive commercial tools
like Mercury (now HP) Quality Center to Selenium. They use Rally for defect
management. 

My highest recommendations are for TeamCity, Nexus, and SVN.

Here's the link to the quickstart:
http://www.nabble.com/file/p23208312/myproject.zip myproject.zip 

Some notes:
1) This won't work as written in Jetty. Jetty uses an unmodifiable map for
request parameters so to make it work in Jetty, one would need to change the
rewrite rule to set a request attribute instead of a request parameter.

2) I had to include the jar for the 3.2.0 version of the URL Rewrite filter
as it isn't in the central Maven repo yet. 

3) Instead of launching to the start page of the app I would recommend going
straight to "http://localhost:8080/whateveryouwant/testpage1";. Replace 
"whateveryouwant" with anything. That's the value that will be rewritten out
of the URL and set as a request parameter with the name "organization". 

4) I'm using the HybridUrlCodingStrategy for URLs. You should be able to use
any URL coding stratgy, but since this is what I'm using in my main app,
it's what I've configured the rule for.

Normal rendering, but as I mentioned later in the thread, even though it was
Wicket issuing the redirect, it was somehow being caused by my attempts at
URL rewriting and the redirects do not occur if the URL manipulation is
disabled.

Re: AjaxLink causing a redirect

[Matt Welch]

Hmmm perhaps it was a byproduct of the URL rewriting. As it turns out,
even with normal PageLinks this redirect occurs. BookmarkablePageLinks do
not cause the redirect. What's odd is that the redirect doesn't actually
change anything. 

With the URL rewriting disabled, there are no redirects. 

Anyway it's no big deal. I think I'm going to have to give up on this URL
rewriting stuff anyway. I was trying out URL Rewrite Filter
(http://tuckey.org/urlrewrite/) and I was getting pretty close to what I
needed (see my original thread on this topic:
http://www.nabble.com/Custom-URL-Handling-to23130367.html which you actually
responded too. You're a busy fellow!). It rewrites both incoming and
outgoing URLs. The incoming rewrites are fairly obvious, but the outbound
ones are done by embedding itself as part of the response.encodeURL() call. 

I managed to get the incoming URL rewrites working perfectly but some of the
outbound URLs refuse to cooperate. Things like Wicket ajax calls and these
redirects were popping up as obstacles. Maybe if I were a little more of a
regex expert I could get this to work, but I'm close to throwing in the
towel at this point.

Thanks. That's something to consider. How did you get wicket to write out

It wouldn't have occurred to me that it would be so difficult. I know it may
seem odd, but URL control is actually very important here because
organization identity is vital in the domain that the app will serve.

Hmmm

Re: Google App Engine and Wicket

[Matt Welch]

Both articles avoid the DiskPageStore problem by using the HttpSessionStore,
however if you do a search through the mailing list archives for
HttpSessionStore you'll find numerous references to problems in using it in
the long term and especially in a real, production application, so I don't
think that's a good long term solution, so my original question still
stands. Is there an alternative or is Wicket perhaps not well suited for use
in the App Engine.

I have no intention of actually deploying it in development mode.

While the link on the original page is still the long version, once it is
clicked I do end up on page with the nicely mounted URL. Thanks!

Are there any gotchas I need to look out for when using this approach?

Thank you for the reply. I guess I'm a little surprised to run into this as
it seems like this would be a pretty common scenario for an application. I'm
certain willing to consider any approach. If forced, I can probably live
with the long, non-bookmarkable url after this login operation if I have to.

Trying to stay stateless but having some issues

[Matt Welch]

I'm trying to keep my app stateless wherever possible, especially on the
pages that serve merely as an introduction to the app but have no heavy
dynamic functionality.

On many of these pages I have a sing-in panel. This sign-in panel contains a
stateless username/password form. The onSubmit of the stateless form looks
like this:


@Override
protected void onSubmit() {
if (GVWebSession.get().authenticate(username, password)) {
if (!continueToOriginalDestination()){
setResponsePage(getPage().getPageClass());
}
} else {
error(getLocalizer().getString("signin.failed", this));
}
}


This doesn't seem to work. The behavior I want pretty common. I want the
same page displayed, but now with the user logged in and the sign-in form
replaced with a "welcome " message or something like that. What actually
occurs is (from the users' point of view) nothing. The page is redisplayed
and the form comes back up. I can debug the form submission and I see that
the users is being properly authenticated. I assume I'm doing something
wrong with my setResponsePage() call. If I comment out that setResponsPage()
call, the login works and the page is displayed correctly but I then have a
long, ugly URL. 

I happen to go to a non-stateless page and a session is created, and then
come back to a stateless page, this login procedure works correctly, so I
assume that my problem has something to do with their not being a session
created yet. That seems odd though, because one wouldn't think my situation
would be that unusual. 

Any suggestions?

LDM with Generics for DropDownChoice

I'm sure I should know this but I can't seem to get it right. I have a

I'm trying to use this as the Choices model in a DropDownChoice, but no

Re: form - ajax submit and validation

[Matt Welch]

I think more information is needed before someone can provide a useful
response:


Are you initializing the AjaxButton with the form (in the the constructor of
the AjaxButton or with setter)?
Is the form data being submitted? If not, this would indicate a problem
somewhere other than in the validation itself.
Can you show your actual code?

Re: Making an invisible panel visible via AjaxLink

[Matt Welch]

The key, as others have alluded to and you discovered yourself, is that
setting a component's visibility to false will cause that component to not
be rendered. I know in the back of some people minds (mine included) we
think "invisible means it's there, we just can't see it). Well, in this case
invisible means it's not rendered at all. This is all just semantics until
you try to change that visibility on the client side (i.e. AJAX). Since it's
not there to being with, you can't really do client side modifications of
it. 

So, as Michael pointed out, you can instead put what you want to make
invisible inside a container and then use the Ajax functionality to update
that container and not the invisible item itself. The container will be
re-rendered and now that the internal item is set to "visible" it will be
rendered right along with its parent container.

Some SignInPanel Questions

[Matt Welch]

I don't know if these are actually SignInPanel (from wicket-auth-roles)
questions or if they're in fact more general "wicket" questions; probably
the latter, but the SignInPanel class is where I noticed these things.

1) In the SignInPanel I notice that instead of having a couple of private
String variables to represent the username and password, a ValueMap is used
instead. I'm curious as to why.  Is there some benefit to using a ValueMap? 

2) When the values that are typed in the username and password fields are
needed to pass to the signIn() method, they are retrieved in ways that I
would not have normally considered. The username value is retrieved with the
getDefaultModelObjectAsString() method of the username's TextField component
and the password is retrieved with the getInput() method of the password's
PasswordTextField component. Why are the values retrieved this way? I assume
there's a good reason, but because I don't understand it, I'm a bit unsure
as to where in my own application I should be using the same techniques.

My first instinct for a panel like this would have been to add two String
variables to the class to act as the model for the username and password
TextFields and then to access those values with normal getter methods. I'd
would find it quite instructive to know why these other approaches were used
instead so that I can take similar actions in my own application.

Thanks!

I'll include some snippets from the SignInPanel class below so that it
doesn't have to be looked up:


-
private final ValueMap properties = new ValueMap();
-
add(username = new TextField("username", new
PropertyModel(properties,
"username")));
add(password = new PasswordTextField("password", new
PropertyModel(properties,
"password")));
-
public String getPassword()
{
return password.getInput();
}
-
public String getUsername()
{
return username.getDefaultModelObjectAsString();
}
-

Re: AjaxSubmitLink submitting twice

[Matt Welch]

I finally did find the root of this problem and wanted to report back to
other Wicket users in case they ever had a similar issue and found this
thread in a search. It turns out that the problem is somehow related to the
Firebug add-on for Firefox. Doing some searching, I can see that Firebug has
had similar issue in the past, however they are supposed all fixed, but the
issue was definitely related, at least in some way, to Firebug. 

Firebug has a feature that allows you put logging statements into your
javascript code with console.log() statements. If that feature was turned on
(i.e. the "Console" option was checked in the "Net" tab of Firebug) then I
would get the behavior I described. Turned off? Everything was fine.

I was using Firebug 1.3.2 with Firefox 3.0. For some reason Firefox had
never prompted me for an update as it had on my other computers. When I
updated to Firefox 3.0.6 I could not longer reproduce the issue. 

The moral, I guess, is to keep your browser up-to-date.

Re: WicketForge 0.5.0 Available for IDEA 8

[Matt Welch]

Perhaps I'm missing it, but I can't seem to get the intentions to work. So if
I have:


public class MyPage extends WebPage {
}

and the cursor is somewhere on "MyPage" I should be able to activate these
intentions? The only intentions I'm seeing now are the built in Idea ones.
Everything else, though, is working beautifully. No more exceptions when
idea loads and having a shortcut key to toggle between the components and
HTML and back is awesome.

Re: Intellij Idea Plugin Bounty

[Matt Welch]

I hope I didn't give the wrong impression. I really appreciate the work
you've done and looking at the code, it's a heck of a lot of work. If I
hadn't tried wicketforge and saw the potential there I never would have been
so motivated to start this process. I just didn't want to be that guy who
just said "I want this" and "I want that" to someone who had already donated
so much of their time. That's why I'm proposing the bounty. That way I can
not feel like such a leech when I ask for specific things.

Intellij Idea Plugin Bounty

[Matt Welch]

I use Intellij Idea for my Java development. In fact, that IDE is one of the
main reasons I so often come back to using Java for many of my projects. I
also use Wicket and am starting to work with it a lot more than I have in
the past. While Wicket and Idea get along reasonably well, there's a lot of
room for improvement in their relationship. That means a Wicket plugin for
Idea. 

Nick Heudecker has done an admirable job with WicketForge
(http://code.google.com/p/wicketforge/), however 1) when I try to use that
plugin, I constantly get exceptions and 2) it doesn't do some of the the
things I'm really interested in. This is no criticism of Nick. If I recall
one of his messages correctly, he developed this plugin for his own use and
it was extremely generous of him to publish the code as open source. He's
even made pretty regular improvements to it, but at least for me personally,
it doesn't meet my needs for a Wicket plugin.

Now, I can't, in good conscience just pop on to this mailing list and ask
someone out of the goodness of their heart to "get to it!", so I'm willing
to start the ball rolling on an incentive in the form of a bounty; one that
I hope other Wicket and Idea users will contribute to as well.  First,
though, I'd like to come to some kind of agreement about a feature set for
such a plugin so that when I post the bounty I can be as specific as
possible in its criteria.

Here is a list of my most desired features in the order of priority:

1) Navigation between template and code - I would like the ability to move
in both directions between a template and it's Java code. This means in an
overall sense (e.g. moving back and forth between a top level page class and
the HTML file) and in a more granular sense (e.g. moving back and forth
between an HTML element with a wicket:id and the Wicket Java Component with
the same id). I should be able to bind a keystroke to this action. It should
preferably be the same keystroke in both directions.

2) Code completion for wicket:message keys - I would like code completion
for the  "key" attribute. It should work something like the
XML code completion when there isn't a DTD or schema available. It would be
based on other keys already available on the page. So for instance if I had
already created a  with a key of
"userform.detailfieldset.username.label" I would expect that when I created
another  and started typing "us" in the key attribute, code
completion would allow me to expand what I typed similar to what happens
when typing package names. 

3) Properties file intention - I would like an Idea intention that would
allow me to automatically add  keys to a resource properties
file. By default this would add it to a properties file with the same name
as the template (even creating the properties file if necessary), however it
should be configurable to use an application-wide properties file if that's
what the user prefers. When adding the key to the properties file it should
be placed in a logical manner according to it's period separated name so the
key "userform.detailfieldset.username.label" would be placed just after
other keys with the name "userform.detailfieldset.username" or
"userform.detailfieldset.username". The intention should leave the cursor
after the "=" in the properties file. 

4) Code completion on wicket tags and attributes - I would like code
completion for all wicket tags (e.g. , ,
etc.) in HTML templates. This is something of a lower priority as Idea's
"Live Template" functionality takes much of the pain out of not having code
completion for items in the wicket namespace. This doesn't help with the
error/warning issue, though.

5) Validation for wicket namespace and attributes in hTML template - In a
similar vein, I would like wicket attributes like "wicket:id" and wicket
tags like  to not show up as either errors or warnings in my
HTML templates. 

This is just off the top of my head. I'm sure there are more and perhaps
even some that should be higher on the priority list. Once some kind of
feature set is agreed by Idea users here in the mailing list, I'll kick off
the bounty on one of the software bounty sites and contribute $200. I know
it's not much but I'll try to get my company to pony up a few dollars as
well. That along with whatever contributions anyone else would like to make
will hopefully be an incentive for someone. Maybe there's someone out there
who's been wanting to do this for a while and the bounty will simply be the
motivation to finally do it. I don't know, but I don't figure there's any
harm in trying. 

Please post your own ideas and list your preferred priority for the
features.

-Matt

Re: AjaxSubmitLink submitting twice

[Matt Welch]

The Nabble posting process correctly escaped all of the HTML tags except the  
which it rendered as HTML. I only just now figured out I needed to use a
"raw" tag. The raw HTML is below.

As expected though, this same code works fine in a quickstart. I never
suspected that it was a bug, which is why I didn't post a JIRA issue. I knew
something this simple wouldn't have been missed. It's clearly a problem with
our configuration, but I don't know where to start looking. 

Using this simple test page, the final rendered page contains no extra
javascript beyond the wicket stuff to support the button submission which I
know works. This test page isn't going through our security framework
because I extended WebPage instead of our application's SecureWebPage (using
wicket-security). That leaves servlet filters (Spring's OpenSessionInView
and the normal WicketFilter), our session implementation or the
WebApplication itself. 

Does anyone have any suggestions about where I might plop down a breakpoint
in an attempt to debug this issue?

AjaxSubmitLink submitting twice

[Matt Welch]

I'm stumped. We have an AjaxSubmitLink and when clicked, the onSubmit of the
link is being executed twice. This is causing havok in our app. I've
winnowed it down to just the simplest example but I still see this taking
place. I'm not sure how to proceed. Here's the example code:
-
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
http://www.w3.org/1999/xhtml"; xml:lang="en" lang="en">



 # Search 



-
public class TestAjaxSubmitLink extends WebPage {
private String fieldValue;

public TestAjaxSubmitLink() {

Form form = new Form("testForm");
add(form);
final TextField search = new TextField("keyword", new 
PropertyModel(this,
"fieldValue"));

form.add(search);
form.add(new AjaxSubmitLink("search"){
protected void onSubmit(AjaxRequestTarget target, Form 
form) {
System.out.println("Clicked Submit");
}
});
}
}
-

We're using an older version of Wicket, but I tested this in 1.3.5 also and
got the same behavior. I find it hard to believe that we would be the first
to experience this behavior so I assume we're doing something wrong, but I'm
just not sure what it is. Any advice?

Re: Checkbox filtering a dataview

[Matt Welch]

Thank you for your reply. Unfortunately (for this situation, anyway), we
frequently reuse our dataproviders in more than one place in the
application, so they are are always in their own class files. In any case,
what we have will work for now. I'll look around through the examples for
other use cases.

Checkbox filtering a dataview

[Matt Welch]

I'm probably thinking about his all wrong, but for some reason I can't get my
mind in the right frame here. I have a page with a dataview that is showing
data in a table. That dataview needs to be filtered by a checkbox in a
different place on same page. The model for that checkbox is an attribute of
the page (using PropertyModel). When I click the checkbox the page needs to
refresh and show filtered data. Obviously the dataview need to know the
current value of that checkbox. The only way I can think to do that is to
pass the page itself to the dataview so that it can call the getter for that
property. This seems convoluted, however. Am I missing something?

Re: Another Ajax back button question

Hmmm... perhaps I shouldn't have abstracted my issue and instead discussed
exactly what is happening. Let me change some steps.

1) On a page with a form I enter information and submit the form

2) The page refreshes (normal submit; not ajax) and a panel that was
previously invisible is displayed as the form submission is processed in the
background. This processing is  background task because it can take a very
long time (anywhere between 5 seconds to half an hour). There is an
AjaxSelfUpdatingTimerBehavior with a 5 seconds time attached to the now
visible panel.

3) The AjaxSelfUpdatingTimerBehavior checks the background process in it's
onPostProcessTarget() method and when the background processing is done, the
panel is made invisible again and new panel is made visible with a link to
report on the processing that just took place.

4) Clicking that link takes one to the report and then clicking that browser
back button brings one back to the form page, however, it apparently brings
one back to the form page in the state it was just after the original submit
was clicked. The actual background processing doesn't get kicked off again,
but the "in progress" panel is visible and remains visible until one cycle
of the AjaxSelfUpdatingTimerBehavior goes by and then the page returns to
the expected state. 

I'd like to figure out a way keep that "in progress" panel from showing up
when the back button is pressed. 

-Matt

Another Ajax back button question

[Matt Welch]

I'm sure this has been asked and answered but after searching the list, I'm
still not sure if there is something I can do to fix my situation. 

The general gist is this:

1) I make some changes to a page with ajax calls (i.e. replace panel
contents)
2) Click a link to take me away from that page
3) Use browser back button to return to previous page
4) Original page is in the state that it was BEFORE the changes made with
the ajax calls.

Maybe this is a, "Well, duh.. of course it is. That's just the way it works"
moment, but I could have sworn I've seen this work differently in other
wicket examples and apps I've worked on. 

Any tips?

-Matt

Thank you. That makes sense to me now. It was a slow brain day day for me I
guess. :)

I know I should understand that, but my brain doesn't want to parse that
sentence for some reason. 

references to injected beans - What does that mean? The domain object is an
injected bean (if it was annotated with @Configurable) and a reference to it
would presumably be passed to the Wicket component so that the that
component could process it. Are you saying that this should be avoided?

other objects - Can you maybe give an example of the "other objects" you
have in mind?

Matt
