Wicket, Guice and the $Proxy object
Hi,
I'm having an issue that I suspect is related to the wicket integration
with Guice. Any help is appreciated.
I have a Page class that uses field injection to inject a DAO. I then want
to cast my DAO to a more specific type (what I inject is the interface).
Here's what that looks like
public class CnavModify extends ConsoleBasePage {
@Inject private CnavUrlDAO cnavUrlDAO;
public CnavModify(PageParameters parameters) {
super(parameters);
if (parameters.get(cnavid).toString() != null) {
cnavid = new ObjectId(parameters.get(cnavid).toString());
}
if (cnavid != null) {
cnavUrlModel = new
DetachableCnavUrlModel(((MorphiaCnavUrlDAO)cnavUrlDAO).getCnavById(cnavid));
}
}
}
When I try to cast it I get the following error:
Last cause: $Proxy23 cannot be cast to
com.hp.honeybadger.persistence.dao.morphia.MorphiaCnavUrlDAO
I am able to use the CnavUrlDAO as a CnavUrlDAO, but its type is $Proxy23
and I am unable to cast it to a concrete type.
Is this Guice or Wicket related? Any idea how to get around this?
Thanks,
Daniel
Re: Wicket, Guice and the $Proxy object
Here's a little more detail when I debug and attempt to do just the cast:
Cannot cast an instance of class $Proxy23 (loaded by instance of
org.eclipse.jetty.webapp.WebAppClassLoader(id=3511)) to an instance of
class com.hp.honeybadger.persistence.dao.morphia.MorphiaCnavUrlDAO (loaded
by instance of sun.misc.Launcher$AppClassLoader(id=2450))

Re: Wicket, Guice and the $Proxy object
That being the case, is there any way to get an instance that I can cast to
a concrete type?

It is an error in your assumption.
Wicket injects a proxy that implements CnavUrlDAO but knows nothing about
the specific implementation about this interface.
Whenever the proxy is used it delegates the call to the bean/service
returned by Guice's injector (something like:
Injector.getBinding(CnavUrlDAO.class).doSomething()).

Daniel
Re: Wicket, Guice and the $Proxy object
Dan,
Good point. After considering I decided to modify my interface to expose
the function I need and let the implementation worry about casting where
necessary.
Thanks,

Re: Form questions
I've had a difficult time following your recommendations. However I think
I'm getting closer.
Part of the disconnect is that right now, as I show above, the model object
I create is in the Form, not the Page. In my Page I create an instance of
my Form like this:
Form form = new CnavForm(cnavForm);
add(form);
So, the first step I've taken is to implement a constructor for my Form
that receives an IModel and, rather than create my CnavUrl, I get it from
the IModel:
CnavUrl cnavUrl = (CnavUrl) model.getObject();
setModel(new Model((Serializable) cnavUrl));
Now I create my Form object like this:
DetachableCnavUrlModel cnavUrlModel = new
DetachableCnavUrlModel(new MorphiaCnavUrl());
Form form = new CnavForm(cnavForm, cnavUrlModel);
add(form);
I'm now at the page level when I create my Model and I have a
DetachableCnavUrlModel, which I also use when displaying them.
if (cnavid != null) {
cnavUrlModel = new
DetachableCnavUrlModel(cnavUrlDAO.getCnavById(cnavid));
} else {
cnavUrlModel = new DetachableCnavUrlModel(new MorphiaCnavUrl());
}
Form form = new CnavForm(cnavForm, cnavUrlModel);
add(form);
This way on edit I have a prepopulated form.
To answer my other question about the link, I created a PageParameters
object and used setResponsePage like this
item.add(new Link(editlink) {
@Override
public void onClick() {
PageParameters editParameters = new
PageParameters();
editParameters.add(cnavid,
((MorphiaCnavUrl)cnavUrl).getId());
setResponsePage(CnavModify.class, editParameters);
}
});
I can then use the value in the parameters to set cnavid
if (parameters.get(cnavid).toString() != null) {
cnavid = new ObjectId(parameters.get(cnavid).toString());
}
Thanks for all the help.

For stateless pages it would create a new one each time (add the DebugBar
to
your pages and see if your page is stateless or not and also see what the
model is per component).
For when Wicket serializes your page, you don't want a PropertyModel alone,
you want a detachable model (see section 9.6 of the Wicket Free Guide or go
over chapter 9 again Wicket models and forms). You need to wrap a
Detachable model inside a Property model like so:
add(new TextField(url, new PropertyModelMorphiaCnavUrl(new
LoadableDetachableModelMorphiaCnavUrl(cnavUrl), URL))
.setRequired(true)
.add(new UrlValidator()));
Is best to use a CompoundPropertyModel for the entire form and get to your
POJO that feeds the entire form (or panel) via a detachable model.
The LoadableDetachableModel is desined to only serialize the record ID for
which you can later retrieve the entire object from your persistence layer.

Subject: Re: Form questions
Paul,
Thanks. I get that and understand how the Model happens. As you can see,
the
instance of the model object is created in the constructor. So the first
question I had is whether a new instance is created for every request or if
there's one instance that's serialized. I suspect it's the second, knowing
how Wicket treats sessions. In that case, I need some way on a per request
basis to load the model from the database.
The other question I had is how to create a link that sends the ID to the
page that renders the form. I need to create a link to that page, include
an
ID value with the request and then access that ID within the form for my
query to load that object from the DB.

So it's the cnavUrl.getUrl() value.
What do you get when you call new MorphiaCnavUrl().getUrl()?
That's what should appear in the TextField when you first load the
page (normally read form the DB).

2) load the object from the database and have it replace the model I create

Obviously I can make a database call and get the object. Is the constructor
called every time the page is requested, so that I could check for an ID
and
either create the model or load it from the database? If so, then I just
need help with #1.

I created a CnavFormPanel.java and changed CnavForm.html to

In CnavModify.java I removed this
Form form = new CnavForm(cnavFormArea);

And added this

That works. Thanks for your help.

Re: Form questions
I've made a lot of progress and been through chapters 9 and 10 of Wicket
Free Guide, but I'm still stumped on point #2, pre-populating the form.
Here's what I have right now:
public class CnavForm extends Form {
@Inject private CnavUrlDAO cnavUrlDAO;
public CnavForm(String id) {
super(id);
CnavUrl cnavUrl = new MorphiaCnavUrl();
setModel(new Model((Serializable) cnavUrl));
add(new TextField(url, new PropertyModel(cnavUrl, URL))
.setRequired(true)
.add(new UrlValidator()));
add(new HiddenField(objectid, new PropertyModel(cnavUrl, id)));
add(new Button(publish) {
@Override
public void onSubmit() {
CnavUrl cnavUrl = (CnavUrl) CnavForm.this.getModelObject();
// check for existing record to know if this is a create or
update
if (((MorphiaCnavUrlModel)cnavUrl).getId() == null) {
// create
cnavUrlDAO.save(cnavUrl);
} else {
// update
cnavUrlDAO.save(cnavUrl);
}
}
});
}
}
I need to know how to do two things.
1) how to link to the page that displays the form, and pass it the ID for
the record I want to edit
2) load the object from the database and have it replace the model I create
in the constructor
Obviously I can make a database call and get the object. Is the constructor
called every time the page is requested, so that I could check for an ID
and either create the model or load it from the database? If so, then I
just need help with #1.
Thanks,
Daniel

FeedbackPanel customization
Hi, I'm working on a modification of the FeedbackPanel to work better with my theme. I would like to prevent the class for the actual message from being appended to. Right now MessageListView is a private final class and the populateItem adds an AttributeModifier to both the label and the listItem. I know I can override getCSSClass, but that still sets it for both the label and listItem. I can't extend just MessageListView since it's private and final. Even if I could subclass that, the FeedbackPanel constructor is called before my subclass of FeedbackPanel, so that it has already used the original MessageListView. Can you think of a clean way to eliminate the AttributeListener on listItem? Daniel
Re: FeedbackPanel customization
Hi Sebastian, I looked at your example, but it's not quite what I need. I want the style applied to 'messages' but not to 'message'. Your example seems to allow for a style to be applied to 'message' and not to 'messages' I've tried implementing it, but that's where I'm stuck. Am I missing something?

Subject: Re: FeedbackPanel customization
Hi Daniel,
In such a case, you have to not use getCSSClass, but override
newMessageDisplayComponent instead.
You have a sample here:
https://github.com/sebfz1/wicket-jquery-ui/blob/master/wicket-jquery-ui/src/
main/java/com/googlecode/wicket/jquery/ui/panel/JQueryFeedbackPanel.java
https://github.com/sebfz1/wicket-jquery-ui/blob/master/wicket-jquery-ui/src/
main/java/com/googlecode/wicket/jquery/ui/panel/JQueryFeedbackPanel.html
Hope this help,
Sebastien.

Hi,
I'm working on a modification of the FeedbackPanel to work better with
my theme. I would like to prevent the class for the actual message
from being appended to. Right now MessageListView is a private final
class and the populateItem adds an AttributeModifier to both the label
and the listItem.
I know I can override getCSSClass, but that still sets it for both the
label and listItem.
I can't extend just MessageListView since it's private and final. Even
if I could subclass that, the FeedbackPanel constructor is called
before my subclass of FeedbackPanel, so that it has already used the
original MessageListView.
Can you think of a clean way to eliminate the AttributeListener on
listItem?

Re: Form questions
Thanks Paul and Sven. I got the form to work and available in the onSubmit
handler.
Now I'm interested in splitting the form out into it's one file. So I
created a class that has nothing more than the form, but I'm not sure how
to include this into a page.
In my class I do this:
public class CnavModify extends ConsoleBasePage {
public CnavModify(PageParameters parameters) {
super(parameters);
Form form = new CnavForm(cnavFormArea);
add(form);
}
}
My CnavModify obviously extends a base page. What do I put inside the
wicket:extend tag to have the form render?

Some problems I can't figure out. The code to create the button complains

add(new Button(publish, model) {

a Button always has a IModelString to fill the value attribute. Note
that in #onSubmit() you're getting the model object of the button, not of
your form.
You can write:
add(new Button(publish, model) {
@Override
public void onSubmit() {
CnavUrl cnavUrl = (CnavUrl) MyForm.this.getModelObject();
System.out.println(publish);
}
});
Using generic types in your code should help you.

Re: DI Through Constructors w/Wicket

Say I have a web page and an email service. I need the email service in the web page. Now everyone is going to say, Simply use field injection. That will work, but makes unit testing a real pain because now I have to setup injection for my unit test (or add additional methods to all of my pages so I can manually set these field, or additional constructors that set these fields). I should be able to unit test a class without needing injection, but instead passing mocks through the constructor. I feel like this is impossible in Wicket currently because the DefaultPageFactory is using reflection to create the page instances instead of the injector (Guice in my case). It would be easy enough to get the injector and call getInstance() to obtain a page instance. The problem is when you need to pass in parameters. There is no concept of parameters for a page other than what is passed via the constructor, so you cannot call something like setPageParameters because it doesn't exist. If using Guice, you could create an @Assisted injection, and have a factory. Has anyone tried creating this type of IPageFactory -- a GuicePageFactory? What kind of pitfalls would exist if I attempted such a thing? Am I being stupid and missing something? Thoughts? Thanks...

Subject: Customizing links in Paging
Hello,
I'm using the Paging functionality with my DataProvider. I've been trying
to
make a simple change, but it's turned out to be very difficult.
Hopefully you can give a little help.
I have a class that extends PagingNavigator and provides markup specific to
my theme. When the paging links render, the current page doesn't render
with
an a tag around it. It's stripped away.
I've traced through and found that this is most likely due to AutoEnable
being set to true in the Link that's created. That choice is hard coded in
to the PagingNavigationLink class.
I'm trying to avoid extending all of the Paging related classes down to the
PagingNavigationLink in order to customize this behavior. Is there some way
to have that active page render inside an a tag with no href?
Thanks,
Daniel

You can construct your page by taking as a constructor parameter a POJO

form GET and POST getting mixed up

I created a single page that shows some data using DataView. I then added a
form and allow a filter argument to be passed in. The problem I'm getting
is that the first time a search is done, the search value is added to the
URL for the page. Subsequent searches are ignored due to the query string.
I have looked for some way to change it to GET, but couldn't find that. I
also looked for some way to prevent the URL from being modified, but I'm
not clear on why that is happening either.
Any idea how to fix this?

}
};

Re: form GET and POST getting mixed up
I found a solution that worked.
I didn't realize that by adding the value passed in to a PageParameters
object and then setting the response page I was telling Wicket to add that
to the URL. I got rid of that.
I changed my form to this use the CompoundPropertyModel:
Form? form = new FormCnavDisplay(searchForm, new
CompoundPropertyModelCnavDisplay(this));
I also added a class attribute for search and moved my onsubmit into a
Button declaration.
final CnavUrlDataProvider dataProvider = new CnavUrlDataProvider();
final TextFieldString searchField = new
TextFieldString(search, new PropertyModel(this,search));
Form? form = new FormCnavDisplay(searchForm, new
CompoundPropertyModelCnavDisplay(this));
Button submitButton = new Button(searchButton) { // (4)
@Override
public void onSubmit() {
if (search != null !search.isEmpty()) {
dataProvider.setSearch(search);
}
}
};
add(form);
form.add(searchField);
form.add(submitButton);

Paging and excessive database access (repeaters)
Hi, I'm following the example in the repeaters section for paging through large amounts of data: http://www.wicket-library.com/wicket-examples-6.0.x/repeater/wicket/bookmarkable/org.apache.wicket.examples.repeater.PagingPage Based on the example and how I've had to implement this there is a lot of data access. First is in the ContactDataProvider. The function iterator queries for the set of data that will be displayed. Next, all the objects that are returned need to be wrapped in a DetachableContactModel. The load mechanism here then loads each individual object from the datastore. In the example, the data is in memory. In a real world scenario the data is likely to be remote and this setup could have a significant performance impact. Is there some way to cut out some of the data access? For example, can I get rid of DetachableContactModel and just use the data retrieved through the ContactDataProvider? Thanks, Daniel

Do all of my classes have to implement serializable in order to use them in Wicket? Daniel
Re: Paging and excessive database access (repeaters)
So what I'm hearing is that I have to use the Detachable model, but that I
can build in some caching to prevent unnecessary datastore access.
Thanks.

This example is not quite optimized. The DetachableContactModel's
constructor is
public DetachableContactModel(Contact c)
{
this(c.getId());
}
but it should be:
public DetachableContactModel(Contact c)
{
this(c.getId());
setObject(c);
}
The way it's done in the example although the model is given the contact,
it stores only its id and needs to load it from the database in order to
access it, even while rendering the table. The way I suggest the model is
given the contact and does not need to load it.
So, the way it's done in the example database access is as follows:
- a list query to get the contacts for a given page
- n queries by id, one for each row
The way I'm suggesting database access is as follows:
- a list query to get the contacts for a give page
- no other queties
If the row contains say a link column that accesses the row model in the
ajax click, then you will see an additional database access by id when the
DetachableContactModel is attached.

Hi,
I'm following the example in the repeaters section for paging through
large
amounts of data:
http://www.wicket-library.com/wicket-examples-6.0.x/repeater/wicket/bookmarkable/org.apache.wicket.examples.repeater.PagingPage
Based on the example and how I've had to implement this there is a lot of
data access. First is in the ContactDataProvider. The function iterator
queries for the set of data that will be displayed.
Next, all the objects that are returned need to be wrapped in
a DetachableContactModel. The load mechanism here then loads each
individual object from the datastore.
In the example, the data is in memory. In a real world scenario the data
is
likely to be remote and this setup could have a significant performance
impact.
Is there some way to cut out some of the data access? For example, can I
get rid of DetachableContactModel and just use the data retrieved through
the ContactDataProvider?
Thanks,
Daniel
Re: Wicket + Guice + unittests
Martin,
In this case it would be just as easy to inject a specific bean.
I did it this way because it matched some other examples that I saw.

Hi Daniel,

// TODO Add your page's components here
QuickLink quickLink = injector.getInstance(QuickLink.class);
add(new Label(quickLink , quickLink.buildQuickLink()));

}
Why do you inject the Injector and then ask it for beans instead of
injecting the bean directly and use it ?

Hi,
I've integrated Guice into Wicket successfully, but I'm struggling
with the unittests. I'm not sure how to get the injector into my
HomePage class. Here's my setup.
I'm using GuiceFilter with a GuiceServletContextListener. That creates
the injector and a ServletModule which defines the WicketApplication.
I followed:
http://code.google.com/p/google-guice/wiki/ServletModule
Here's some of MyGuiceServletConfig extends GuiceServletContextListener
@Override
protected Injector getInjector() {
return Guice.createInjector(createServletModule(), new
MongoHoneybadgerModule());
}
private ServletModule createServletModule() {
return new ServletModule() {
...
In my WicketApplication extends WebApplication I have this init() method
@Override
public void init()
{
super.init();
Injector bootStrapInjector = (Injector)
this.getServletContext().getAttribute(Injector.class.getName());
getComponentInstantiationListeners().add(new
GuiceComponentInjector(this, bootStrapInjector));
}
Now, in my HomePage.java class I have
public class HomePage extends WebPage {
private static final long serialVersionUID = 1L;
@Inject private Injector injector;
public HomePage(final PageParameters parameters) {
super(parameters);
SomeType myobj = injector.getInstance(SomeType.class);
add(new Label(version, myobj.getValue()));
}
}
This all runs great inside a web container as a servlet.
The PROBLEM: I'm getting a NullPointerException on the line where I
reference the injector:
SomeType myobj = injector.getInstance(SomeType.class);
My test class is what was generated by the wicket quickstart. I'm not
sure how to make an injector available in setUp.
@Before
public void setUp() {
tester = new WicketTester(new WicketApplication());
}
Any ideas?
Thanks,
Daniel

this.getServletContext().getAttribute(Injector.class.getName());
getComponentInstantiationListeners().add(new
GuiceComponentInjector(this, bootStrapInjector));
}
Now, in my HomePage.java class I have
public class HomePage extends WebPage {
private static final long serialVersionUID = 1L;
@Inject private Injector injector;
public HomePage(final PageParameters parameters) {
super(parameters);
SomeType myobj = injector.getInstance(SomeType.class);
add(new Label(version, myobj.getValue()));
}
}
This all runs great inside a web container as a servlet.
The PROBLEM: I'm getting a NullPointerException on the line where I
reference the injector:
SomeType myobj = injector.getInstance(SomeType.class);
My test class is what was generated by the wicket quickstart. I'm not
sure how to make an injector available in setUp.
@Before
public void setUp() {
tester = new WicketTester(new WicketApplication());
}
Any ideas?
Thanks,
Daniel

Re: Wicket + Guice + unittests
Thanks Ronan,
Can you share the implementation of StubProjectorApplication? That
doesn't appear to be part of Wicket or Guice.

Hi Daniel,
I'm using Guice in a couple of wicket projects though my understanding of it
is a little limited! My set-up matches yours except that in my unit test
setup I call injectMembers :
@Before
public void setUp()
{
final StubProjectorApplication stubApplication = new
StubProjectorApplication();
_tester = new WicketTester(stubApplication);
stubApplication.getWarpInjector().injectMembers(this); //
getWarpInjector returns the injector built in the init method
}
I'm not sure this is right..it feels to me that it shouldn't be be
necessary, but it works for me :) .

Hi,
I've integrated Guice into Wicket successfully, but I'm struggling
with the unittests. I'm not sure how to get the injector into my
HomePage class. Here's my setup.
I'm using GuiceFilter with a GuiceServletContextListener. That creates
the injector and a ServletModule which defines the WicketApplication.
I followed:
http://code.google.com/p/google-guice/wiki/ServletModule
Here's some of MyGuiceServletConfig extends GuiceServletContextListener
@Override
protected Injector getInjector() {
return Guice.createInjector(createServletModule(), new
MongoHoneybadgerModule());
}
private ServletModule createServletModule() {
return new ServletModule() {
...
In my WicketApplication extends WebApplication I have this init() method
@Override
public void init()
{
super.init();
Injector bootStrapInjector = (Injector)
this.getServletContext().getAttribute(Injector.class.getName());
getComponentInstantiationListeners().add(new
GuiceComponentInjector(this, bootStrapInjector));
}

Re: Reload html in Wicket + GAE
Thanks Martin,
I did make that much progress yesterday after sending this, but I
can't figure out how to get the Application inside the onBeginRequest
method that I override. In the other examples they call
getApplication()
@Override
protected void onBeginRequest() {
if
(getApplication().getConfigurationType().equals(Application.DEVELOPMENT))
{
final GaeModificationWatcher resourceWatcher =
(GaeModificationWatcher) getApplication()
.getResourceSettings().getResourceWatcher(true);
resourceWatcher.checkResources();
}
}
How can I get the Application object?

Once you have it you can contribute it to gae-initializer project so

Re: Reload html in Wicket + GAE
I've now created a class MyRequestCycleListener extends

I'm having a little trouble building class GaeModificationWatcher

http://agilewombat.blogspot.com/2010/01/wicket-on-google-app-engine.html

It seems no matter which Entry class I import I get errors like:
Multiple markers at this line
- Entry cannot be resolved to a type
- The constructor
HashSetEntryIModifiable,SetIChangeListener(SetMap.EntryIModifiable,SetIChangeListener)

Re: Reload html in Wicket + GAE
So I was just looking at what I sent along and it seems that
putIfAbsent(modifiable, new HashSetIChangeListener()) should return
the value component, which should be the new HashSetIChangeListener.
Even if the key modifiable already exists, it should return the
previously created HashSetIChangeListener.
I'm confused that listener is coming back null.

what Entry class to import. I have tried importing these two Entry

org.apache.wicket.util.collections.IntHashMap.Entry

It seems no matter which Entry class I import I get errors like:

- Incorrect number of arguments for type IntHashMap.Entry; it

Reload html in Wicket + GAE
Hi, I'm following up on a previous thread that's still unresolved. I would like GAE to automatically reload my HTML when I save changes. Classes are reloaded when I save (compile) them, but I have to restart each time for HTML changes. There are some old articles that show how to do this, but they deal with older versions of Wicket and GAE. For example: http://agilewombat.blogspot.com/2010/01/wicket-on-google-app-engine.html http://apache-wicket.1842946.n4.nabble.com/How-can-I-reload-HTML-in-app-engine-td3005241.html http://code.google.com/p/kickat26/source/browse/trunk/src/de/kickat26/ui/wicket/GAEModificationWatcher.java Those suggest creating a class MyWebRequestCycle extends WebRequestCycle, but wicket 1.5 doesn't have WebRequestCycle. How can I accomplish this same thing in the current version of wicket?

Re: AJAX Rating extension, multiple on a page
It turned out to be easier than I thought (must not have been thinking
in the wicket way).
Here's what I do (notice that inside populateItem I have access to
movieItem, which I can use to getModelObject()):
// Add movieListView of existing movies
moviesForm.add(new PropertyListViewMovie(movies, movieList) {
@Override
public void populateItem(final ListItemMovie movieItem) {
final RatingModel rating = new
RatingModel(movieItem.getModelObject().getRating());
movieItem.add(new
TextFieldString(name).setType(String.class));
movieItem.add(new DropDownChoiceCategory(category,
Arrays.asList(Category.values()), new
EnumChoiceRendererCategory(this)));
movieItem.add(new RatingPanel (rating, new
PropertyModelInteger(rating, rating), 5, new
PropertyModelInteger(rating, numberOfVotes), false) {
@Override
public boolean onIsStarActive(int star) {
return rating.isActive(star);
}
@Override
public void onRated(int newRating,
AjaxRequestTarget target) {
movieItem.getModelObject().setRating(newRating);
rating.updateRating(newRating);
Session session =
HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
session.update(movieItem.getModelObject());
session.getTransaction().commit();
movieList.detach();
}
});
movieItem.add(new Link(removeLink) {
@Override
public void onClick() {
System.out.print(movieItem.getModelObject().getId());
Session session =
HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
session.delete(movieItem.getModelObject());

Just to be clear in case it wasn't obvious- thingBeingRated will be
serialized with the rest of your page if you take this approach. If it's not
serializable, use a reference (like a database ID) to look it up when

form processing for multiple objects
I have populated a form with values representing several different
objects. This is what my markup looks like:
form wicket:id = moviesForm id = moviesForm
span wicket:id = movies id = movies
a wicket:id = removeLink(remove)/a
input type=text wicket:id=name class=nospam/
select wicket:id=category/
span wicket:id=ratingrating/span
br /
/span
input type = submit value = Update Movies id=formsubmit/
/form
The span is reproduced for each object that I pull from a database.
There is a different identifier for each span, as you can see here:
http://screencast.com/t/l8pLGZnJVn8
I want to be able to access these objects when I click submit the
form, but I'm not sure how to get access to them. This is what I have
tried so far:
Form moviesForm = new FormValueMap(moviesForm) {
/**
* Show the resulting valid new movie
*/
@Override
public final void onSubmit() {
ValueMap values = getModelObject();
// perform validation and security here
if (StringUtils.isBlank((String) values.get(name))) {
error(Received bad input!!!);
return;
}
Session session =
HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
Movie movie = new Movie();
movie.setName((String) values.get(name));
movie.setCategory((Category) values.get(category));
session.save(movie);
session.getTransaction().commit();
}
};
The ValueMap values comes back null from getModelObject(). Any
pointers for me to get these objects back in a way that I can easily
update them?
Thanks.

Re: form processing for multiple objects
Let me give a little more detail. The way that markup is managed is
through this:
// Add movieListView of existing movies
moviesForm.add(new PropertyListViewMovie(movies, movieList) {
@Override
public void populateItem(final ListItemMovie movieItem) {
final RatingModel rating = new
RatingModel(movieItem.getModelObject().getRating());
movieItem.add(new
TextFieldString(name).setType(String.class));
movieItem.add(new DropDownChoiceCategory(category,
Arrays.asList(Category.values()), new
EnumChoiceRendererCategory(this)));
movieItem.add(new RatingPanel (rating, new
PropertyModelInteger(rating, rating), 5, new
PropertyModelInteger(rating, numberOfVotes), false) {
@Override
public boolean onIsStarActive(int star) {
return rating.isActive(star);
}
@Override
public void onRated(int newRating,
AjaxRequestTarget target) {
movieItem.getModelObject().setRating(newRating);
rating.updateRating(newRating);
Session session =
HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
session.update(movieItem.getModelObject());
session.getTransaction().commit();
movieList.detach();
}
});
movieItem.add(new Link(removeLink) {
@Override
public void onClick() {
System.out.print(movieItem.getModelObject().getId());
Session session =
HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
session.delete(movieItem.getModelObject());
session.getTransaction().commit();
movieList.detach();
}
});
}
}).setVersioned(false);
I suppose that means that I'm not actually adding new items to the
list as a form. Maybe what I need is to treat the entire component as
a form from the beginning. I'm just not sure exactly how to do that.
Any ideas?

Re: form processing for multiple objects
Note that I can access the objects that I populate using a
PropertyListView individually just fine.
What I am trying to do now is access them as part of a larger form so
that I can update multiple items at once. I was hoping to be able to
iterate through the items that the PropertyListView had rendered so
that I can update them one by one. That's where I'm failing. That Form
and onSubmit are defined outside of the PropertyListView.
I'm sorry if I'm not explaining this very well.

That was the only error produced when running build. However, I tried

I had errors outside of wicket, related to hibernate.

guestbook application with database update
I'm creating a small app based on the guestbook:
http://www.wicket-library.com/wicket-examples/guestbook/?1
In the guestbook app, the page view is updated every time a new
comment is added. The variable commentList is initialized at the top
like this
private static final ListComment commentList = new ArrayListComment();
// Add commentListView of existing comments
add(new PropertyListViewComment(comments, commentList)
{
@Override
public void populateItem(final ListItemComment listItem)
{
listItem.add(new Label(date));
listItem.add(new MultiLineLabel(text));
}
}).setVersioned(false);
I wanted to use a database instead, so I made the following changes
private ListMovie movieList = new ArrayListMovie();
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
movieList = session.createQuery(from Movie).list();
session.getTransaction().commit();
// Add commentListView of existing comments
add(new PropertyListViewMovie(movies, movieList) {
@Override
public void populateItem(final ListItemMovie listItem) {
listItem.add(new
TextFieldString(name).setType(String.class));
listItem.add(new DropDownChoiceCategory(category,
Arrays.asList(Category.values()), new
EnumChoiceRendererCategory(this)));
listItem.add(new Label(rating));
}
}).setVersioned(false);
With this change, all the items in the database come up when the page
first loads, but not after each new item is added to the database. I
have to clear out the URL and load the page fresh to see what has been
added since the last fresh load.
I did try resetting movieList in the onSubmit function to load the
current database items into the variable movieList, but that still
doesn't update the list.
Any idea how to update movieList after each new item is submitted.

AJAX Rating extension, multiple on a page
Hi,
I've been working with the Rating extension found here:
http://www.wicket-library.com/wicket-examples/ajax/ratings?0
I have a case where I need to render multiple on a page, and they
render fine. Each rating panel that displays corresponds to a specific
record in a database. I would like to be able to get information from
the request to indicate which record the rating is for.
The RatingPanel as a method onRated that accepts the rating and runs
an update, like this:
@Override
public void onRated(int rating, AjaxRequestTarget target) {
HomePage.rating.addRating(rating);
}
I also noticed that the URL contains some additional information
a href=?0-4.ILinkListener-movies-0-rating-rater-element-0-link
wicket:id=link id=linkbb onclick=var
wcall=wicketAjaxGet(#039;?0-4.IBehaviorListener.0-movies-0-rating-rater-element-0-link#039;,function()
{ }.bind(this),function() { }.bind(this), function() {return
Wicket.$(#039;linkbb#039;) != null;}.bind(this));return
!wcall;img wicket:id=star
src=wicket/resource/org.apache.wicket.extensions.rating.RatingPanel/star1-ver-1326919989539.gif//a
The number between ...movies-_-rating... (where the underscore is) is
different for each group.
Is there some direct way to access information about the URL or to
modify this extension to pass the record information along with it?
Thanks,
Daniel

does the breadcrumb extension support bookmarkable links?
I've been working with the breadcrumb components in the extensions library today. Now that I have it working the way I need it to, I noticed that none of the links are bookmarkable. I wondered if it were possible to use this feature and still have links be bookmarkable? I did some searching and found only a handful of references to creating bookmarkable pages instead of panels, but before I went too far down that road I wanted to ask if it's possible and straight forward.

Re: Wicket on Google App Engine

Re: Wicket on Google App Engine
Hielke, I'm not very sophisticated when it comes to Maven. I think what I go through in my tutorial is more of a brute force update of my eclipse environment so that it works with the quickstart project on GAE.

I have to admit that I'm not very savvy when it comes to Maven and I like the eclipse environment well enough. The Eclipse + GAE plugin makes development easy.

I now use maven's resources plugin to copy the resources from the maven repository to the war/lib folder. Which allows me to update/add dependencies in the pom.xml, run maven and add the dependencies in eclipse manually. I have not found a maven plugin which just adds the google sdk as dependency for me so I don't have to mess around in eclipse everytime I run maven. Did you solve that?

I know that when I run a quickstart app directly (using the Start class) that updates to the HTML are updated without requiring a restart.

Great. I now have it working with either the jar download or the dependency in the pom.xml file. In the dependency xml snippet I didn't realize that I needed to manually provide the version, but after I did then it worked fine. Whenever I update a class and save it in Eclipse, that class is updated in the running server and I don't have to restart to see the changes. This is great. However, when I change an HTML page, it's not updated in the running server, so I have to restart everything. I know that when I run a quickstart app directly (using the Start class) that updates to the HTML are updated without requiring a restart. Do you know how to make it so the HTML files are updated in the live server? Thanks so much.

Re: Wicket on Google App Engine
I tried putting in this: getResourceSettings().setResourcePollFrequency(Duration.ONE_SECOND); But the resource still doesn't update without restarting the google app engine environment. I just tried it by running Start and that no longer updates automatically either. In the process of trying to make it work with GAE, I changed the pom.xml to have these lines in the build section directorysrc/main/webapp/WEB-INF/directory outputDirectorysrc/main/webapp/WEB-INF/classes/outputDirectory That means files are no longer placed in the target directory, but in the WEB-INF folder. Could this affect it? Have I missed another setting somewhere that relates to changing where the compiled classes are placed?

Wicket on Google App Engine
Hi, I've been working for a few days to get a wicket application going for Google App Engine with mixed results. I hope these questions aren't too noobie for this list? There are a couple of really old articles which Google brings up first: http://stronglytypedblog.blogspot.com/2009/04/wicket-on-google-app-engine.html http://www.danwalmsley.com/2009/04/08/apache-wicket-on-google-app-engine-for-java/ I've also found this resource after digging through the wicket users list, but I can't figure out how I'm supposed to use it: https://github.com/wicketstuff/core/tree/master/jdk-1.6-parent/gae-initializer-parent I'm using eclipse with the GAE plugin. So far this is what I have accomplished. 1) the first link above provides a download demo as an eclipse project. I can get this to run, but it's working with old versions (wicket 1.3.5, appengine sdk 1.2.0). I haven't successfully updated. 2) I can create a new google app engine project in eclipse. It runs fine and I can develop servlets. 3) I can user the maven build script from the quickstart to get a functional wicket project. I'm really struggling trying to figure out how to use the gae-initializer or a base GAE project from eclipse and end up with a functional wicket application... I'm not sure what other information to include at this point. Please share any pointers or links to other tutorials that might help me.

RE: best way to accommodate dynamic properties
I'm still trying to figure this out. I would like to be able to do something
like the following:
HTML:
img wicket:id=testimage
JAVA:
public class ImageTestPage extends WebPage{
public ImageTestPage() {
Image myImg = new Image(testimage);
myImg.setUrlForImageSrc(http://path/to/image.gif;);
myImg.setWidth(200);
myImg.setHeight(100);
add(myImg);
}
}
Obviously the Image class doesn't work that way... Can someone tell me how I
would accomplish this so that I can define the image, height and width
independent from the markup?
Daniel

Subject: best way to accommodate dynamic properties
I'm interested in having pulling the width and height for an img from a
database, but I'm not sure what the best way is to create a component and
corresponding HTML mapping.
Please send an example or link to previous response if possible. I've searched
the users list archives but didn't find what I was looking for.
Thanks.
