Re: [ANN] wicketstuff-lazymodel

[Martin Grigorov]

Hi Sven,

I think it would be useful if you add an explanation to the wiki page how
it works.
As far as I see from the code it is based on reflection by using Objenesis.

I also saw performance tests which verify that LazyModel is at least twice
faster than PropertyModel. This information may be used as an advertisement
in the Wiki page!

Also I think there is an error in this example:


 private static final IModel B = model(from(A.class).getB());

  IModel a = ...;

  add(new TextField("b", B.bind(a));


I don't see how 'B' can have method #bind(IModel) unless the IModel in the
example is some other class, not the one in wicket-core.

Oopsy is not necessary :-)  Depending on the Use Case, both ways are fully
okay.
If you pass MyClass.class then, as stated before, Wicket creates a fresh
page for you. If you pass an instance, then wicket uses that instance. The
2nd approach can for instance be used if you have state (i.e. a model or
something else) to pass to the new page, but not necessarily.

Re: Label with default text if model empty + CompoundPropertyModel

[Sven Meier]

You can override Label#initModel():

protected IModel initModel()
{
return new DefaultTextModel(defaultModel, super.initModel());
}

A simpler solution is to override Label#onComponentTagBody() and just 
apply your default text there.

Re: Why does my "HelloWorldPage" not work?

[Ondrej Zizka]

Hi Mike,

These problems are not wicket specific.
I'd suggest to make your life easier and switch to Maven.
Then, Maven and IDE would handle most of the dependencies for you - e.g. 
NetBeans searches all Maven repo for classes of given name, and adds it 
to dependencies.


Otherwise, the process goes like:

1) If you see Caused by: java.lang.NoClassDefFoundError: Lorg/slf4j/Logger;
2) Google for org.slf4j.Logger
3) Download latest version of the containing library and put it to your libs
4) Go to 1)

Based on the path I was taking, the redirect URI is the key.  Facebook 
redirects as such:

YOUR_REDIRECT_URI?
access_token=USER_ACCESS_TOKEN
   &expires_in=NUMBER_OF_SECONDS_UNTIL_TOKEN_EXPIRES
   &state=YOUR_STATE_VALUE

Of course, if the request fails authentication, they redirect as follows:

YOUR_REDIRECT_URI?
error_reason=user_denied
   &error=access_denied
   &error_description=The+user+denied+your+request.
   &state=YOUR_STATE_VALUE

So your redirect page could start out like this:

public class FacebookResponseListener extends WebPage {

private static final long serialVersionUID = 1L;

public FacebookResponseListener(PageParameters params) {
// if there is an error, handle it
if (params.get("error_reason") != null) {
// handle the error here!
} else {
String accessToken = 
params.get("access_token").toString();
int expiresIn = params.get("expires_in").toInt();

// etc... etc...

}

}
}

The browser gets a token back that makes perfect sense and the example is

Right.  In the Scribe example, you are working in the console so a "code" is 
provided that you punch in to your console which gets consumed by a Verifier.  
I don't believe it will work that way in an actual seemless integration.  
Instead, you should be able to define a "OAuth Accept Redirect URL" which 
effectively informs Facebook to post back the credentials to that URL you 
specify.  Here is where I am assuming since I haven't completed the 
integration... instead of getting an access token by sending the Verifer 
instance back to Facebook with the request token, Facebook should post the 
access token to your OAuth Accept Redirect URL which you can consume and set to 
a Token instance.  Again, I'm assuming at this point.  It's possible that your 
OAuth Accept Redirect URL consumes that code and then you're expected to 
request the access token at that point...

Go to your Facebook App in the Developers console and define a URL for the 
OAuth Redirect URI.  Put something together and try it.  I believe it will send 
back an access token in the query string if memory serves.

When I have something working, I'll gladly share it with you to provide 
clarification.

Mike

For generating binaries, I would *really* recommend doing this change.
Pages simply are not a good fit for that. Also, it shouldn't be that
big of a change, since you're writing to the Response anyway. Within
AbstractResource's WriteCallback you're going to use the same Response
object, so you can simply copy most of your code over without much
change.

(pseudocode from memory, but close enough)

MyResource extends AbstractResource {
 @Override newResourceResponse(Attributes att) {
  att.setFilename("foo.pdf");
  att.disableCaching();
  att.setContentType("text/pdf");
  att.setWriteCallback(new WriteCallback() {
@Override writeData(Attributes att) {
  Response r = att.getResponse();
  // write to the response here like you did before
}
  });
 }
}

Except in this case you won't have to mangle the Response object like
you have to do with the page.

RE: Anyone using Wicket-Stuff Facebook

I also plan to use Scribe and spent a little time with it this weekend.  My 
particular example uses LinkedIn, but the implementations would probably be 
near identical.  In this particular example, I'm trying to retrieve the 
Authorize URL that a user would use to authenticate with LinkedIn.  The 
following method returns the API hyperlink that I would use for a "Login with 
LinkedIn" button:

private String getLinkedInAuth() {
OAuthService service = new ServiceBuilder()
.provider(LinkedInApi.class)
.apiKey("your_api_key").apiSecret("your_api_secret_hash").build();

Token requestToken = service.getRequestToken();
String link = service.getAuthorizationUrl(requestToken);

return link;
}

I haven't done much from there, but I believe you should be able to define a 
return URL when a user successfully authenticates that you host (check your 
Facebook app config on Facebook.com).  That URL should be prepared to accept a 
response that will include the user's access token which you will use to sign 
any of your graph api requests.

I haven't completed my integration so hopefully I am not over simplifying.

RE: Fundamental forms/models issue

[Michael Chandler]

To conclude, my issues stemmed from not properly linking from page to page.  I 
did a lot of this:

BookmarkablePageLink("link", MyClass.class);

Instead of this:

Link("link") {
public void onClick() {
setResponsePage(new MyClass());
}
}

Oopsy!

I can see how the former might benefit me down the road, but not for general 
use.

Thanks again everyone.

Nice - the addResourceReplacement is great.  Thanks Martin - I will
try to upgrade the application soon.  In the meantime, I will override

Francois, I'm sorry to belabor this question - but I just want to make
sure I'm not missing something still.  I think I understand what to do
now and it works - I was just pointing out that if I extend the
MultiFileUploadField class, it is not enough to only override that one
method, because the reference to those 3 variables in my overridden
method would be trying to reference private members from the super
class and won't be allowed.  So, I just need to also create a new
version of the variables in the extended class, and override the
constructors in which they are defined, and any other methods in which
they are referenced.  Were you saying in your last response that this
is not necessary, for some reason that I'm still missing?  In any
case, doing it this way works and is fine as a temporary solution
until I upgrade and can use the addResourceReplacement approach.
Thanks again for all the help!

Best,
-Evan

Since a Wicket WebPage has it's constructor invoked only one time in the 
application lifecycle


Usually a new page instance is created each time you visit a bookmarkable url. 
WebPages are never shared between clients.

There is the mistake: Page instances are *not* shared. Every user has
their own instances. There can be plenty of instances of any page at
any given time.

Pages get constructed any time *you* do it (by calling new MyPage(...))
or Wicket does it (when the user first gets to a bookmarkable page,
Wicket will construct a fresh instance by using either the no-arg
constructor or the PageParameters constructor).

One - unfortunately - big reason: it's legacy code (most of

code if it's not absolutely necessary.

Fundamental forms/models issue

[Michael Chandler]

Good morning/afternoon everyone.

I'm having a basic problem fully deciphering how to best manage my forms, 
specifically related to Models that are attached to forms.  Since a Wicket 
WebPage has it's constructor invoked only one time in the application 
lifecycle, I'm failing to fully understand how to present a form that has a 
model bound to it without inadvertently sharing that instance of the Model with 
every user of the application.  It seems like a fundamental issue that I'm 
failing to fully grasp and could use some input.

As an example, I have the following in my constructor:

LoadableDetachableModel jobModel = new LoadableDetachableModel() {

 private static final long serialVersionUID = 1L;

 @Override
 protected Job load() {
   Job job = (Job) EntityFactory.getInstance().getBean("job");

   // if we're editing an existing job, load the object
   if (jobId >= 1) {
job.load(jobId);
   }

   return job;
 }

};

I later create a form and after adding it in my constructor, bind the model to 
it as follows:

jobForm.setModel(new CompoundPropertyModel(jobModel));

As you can imagine, every user session from this point on now has that instance 
of a Job object bound to that form due to these declarations being in the page 
constructor.  I have come a long way on my own, but I'm at a point where I 
clearly do not have a full grasp of how to best approach this.  I suspect I can 
potentially override an instance of a Model's getObject() method for more 
dynamic behavior, but I'm concerned about writing code that becomes too verbose 
when perhaps there's a better/tighter way to handle this.  Can anyone advise me?

Many thanks!

[ANN] wicketstuff-lazymodel

[Sven Meier]

Hi all,

I've added a new module to wicketstuff:

LazyModel offers lazy evaluation of method invocations. It takes the 
best from present solutions (safemodel and modelfactory) and improves on 
reflection to support:


* arbitrary parameters
* generics
* collections
* interfaces

Two simple examples:

IModel model = model(from(a).getB().getStrings().get("key"));

new LazyColumn(header, from(A.class).getB());

Read more here:

Have fun

Re: Migration issue: page that writes binary data to the response

[Carl-Eric Menzel]

I would simply do this in a Resource (e.g. subclass AbstractResource)
rather than in a page. Resources are for binary data, Pages are for
markup. That way you don't have to mess around in any way with the
response or anything like that.

Is there a particular reason you're using a page?

Migration issue: page that writes binary data to the response

[Martin Dietze]

In the project I'm currently porting from 1.4.x to 6.6.0 I've
run into an issue with Wicket pages which stream binary data
into the WebResponse (e.g. ZIP archives created on the fly).

First thing I found was that obviously I *have* to create
templates for these pages even though they are not going to be
used for anything. 

The second thing is more serious: when writing to the response I
get an IllegalStateException as the template code has already
been written to it. This can be circumvented by calling
Response.reset() before Response.write() in my code. However in
development mode I still get an ISE as in Page.onAfterRender()
there's this code here:

| if (getApplication().getDebugSettings().isOutputMarkupContainerClassName())
| {
| String className = Classes.name(getClass());
| getResponse().write("\n");
| }

}
Now of course I can write:

| @Override
| protected void onAfterRender() {
|   try { super.onAfterRender(); } catch (IllegalStateException e) { }
| }

... but I guess we agree that while this works it is far from nice.

I am not sure if I understand correctly what the above code is
trying to tell me. Does it mean that I am simply not supposed to
deliver my ZIP files by a Wicket page that way? 

If with today's Wicket version there's a different or even better
way to do this, which one would that be?

Else, would there be any harm in making the Page class more
friendly to this kind of use, by e.g. putting the above
if-statement into an overridable method and adding an option to
the Component class to tell it that there's no markup for it and
it should simply not expect any?

Cheers,

M'bert

Re: Redirect to the HomePage on newSession

You can always throw a RestartResponseAtInterceptPageException(Page) and
let Wicket do the redirect for you.

Re: Several Form onSubmit, is it possible add via AbstractBehavior?

[Paul Bors]

As per the JavaDocs:
http://ci.apache.org/projects/wicket/apidocs/1.5.x/org/apache/wicket/ajax/markup/html/form/AjaxFallbackButton.html#onSubmit(org.apache.wicket.ajax.AjaxRequestTarget,
org.apache.wicket.markup.html.form.Form)
Callback for the onClick event. If ajax failed and this event was generated
via a normal submission, the target argument will be null

*Parameters:*target - ajax target if this linked was invoked using ajax,
null otherwise
I belive your target is null because you are using a fallback button and
you might have JavaScript turned off in your browser?

Do not add anything!

Just remove all jars but wicket-core.jar, wicket-util.jar and

Thank you!
But the "HelloWorld" demo is very simple,and it doesn't need some extra jar
files!
When I added the "velocity-1.7.jar" file,the above errors has happened.

So I don't know what to do.

I think you don't need Velocity for a Hello World application. You also
mentioned that you are a beginner ...
Just remove wicket-velocity.jar and velocity.jar from your app.

Those errors are not exactly wicket related... It is just that you are
including jars that need other jars to function properly. Either you
include those jar manually on class path (aka WEB-INF/lib) or your
application start using some dependency management tool.

Re: Submit form before handle onclick

[Martin Grigorov]

I thought you don't want form A to be submitted and its model updated.
Otherwise why you have two forms ?

Otherwise use what Ernesto suggested - AjaxFormComponentUpdatingBehavior
for each 'required' component of form A.

Isn't this a matter of just attaching an AjaxFormComponentUpdatingBehavior

Re: Submit form before handle onclick

[Gonzalo Aguilar Delgado]

Hi Martin, 

Thank you for your answer. 

What about doing like google and others? I mean save (submit) on lost
focus... So the model will get updated every time you leave a field.

Any good references?

thank you.

[mike.hua]

Is there any solutions without maven?
Because I've never used it,and I am a new "Java Web" developer!
Before using Java, I have used ASP.NET 2.0 for about 7 years.

Re: Submit form before handle onclick

[Martin Grigorov]

Hi,

I think this is not possible if you use two root forms.
You need to submit them by order (first A and then B) to have the values.

You can use nested forms though. B should be inside A.
This way when you submit B Wicket will post all the data (for both A and B)
but will process only form B. The values of the form components of A will
be available thru request.getPostRequestParameters().get("someFromA")

Re: Submit form before handle onclick

[Gonzalo Aguilar Delgado]

Hi Martin, 

Ok. I will take a look to this but I think it's not the right solution. 

Suppose this:
-
PAGE Example|
---
A <- This is a form.  | B <- This is a form.|
---|


Supppose that you want to process form B with Ajax but you also need the
information the user typed on A. 

How can you do it? With ajax of course?

I will submit A so the model of A gets updated, and after I will submit
B. So B has the model of A and B loaded.

Is there a better way to do it?

Re: Handle the modal window size?

[Martin Grigorov]

Hi,

The only way I see is to "extend" (monkey patch) Wicket.Window#resizing()
method. That contribute your own .js file that defines
Wicket.Window.resizing function.
To find the new sizes see the various #onResizeXyz methods

Martin, thanks for your reply.But I need that when the user *resize* the
modal window *by mouse*. Can I get the new dimensions(changed by mouse). If
I can get, then i will save it to session. So, modal window will be created
these values.

Re: how to modify internal JavascriptResourceReference packaged with component

Hi,

This is improved in Wicket 6.
You can use
org.apache.wicket.protocol.http.WebApplication#addResourceReplacement for
exactly this use case.
See http://wicketinaction.com/2012/07/wicket-6-resource-management/
You are recommended to upgrade your application.

Re: Forward request to an external filter

[Martin Grigorov]

Hi,

Wicket doesn't provide an API for internal forwards. Use the Servlet API
for this.

Also check https://github.com/fernandezpablo85/scribe-java for OAuth. It is
very simple to use it.

It is not "per Jetty server".
src/main/webapp is the standard folder where WEB-INF/ is in Maven-like
projects (Gradle, SBT, Buildr also use this as default).
'webContent' is what your IDE uses as a folder for all web resources. This
differs for every IDE.

In the end all that matters is the built .war file. I recommend you to get
familiar with its structure.
