Re: Is Wicket In Action still relevant?

[James Selvakumar]

Hi all,

Thank you very much for all your replies.
Like Stan, I too learned Wicket primarily through Wicket In Action and like
it very much.
Thanks Andrea, for the pointer to Wicket Guide. It's very nice.
I'll use both the book and the guide to train our new resources.

Is Wicket In Action still relevant?

[James Selvakumar]

Hi all,

Just wondering whether Wicket in Action is still relevant with all the
recent changes to Wicket? Can it be used to help a new developer understand
Wicket?

Hi Martin,

Thank you very much for the response.
I'll check that out.

Displaying a Jenkins like "Getting ready to work" message in a web page when application is starting up

[James Selvakumar]

Hi all,

First of all I would like to thank the community for all the help offered
in the past. Thank you very much.

My application (Wicket + Spring + Hibernate) takes around 60 to 90 seconds
to startup and all the user has to see is an empty browser tab when the
application is starting up.
I've observed Jenkins displaying a familiar "Getting ready to work" message
when it starts up.
I've seen some Atlassian products even displaying what's happening behind
the hood during startup.
Can someone explain how to do something similar with Wicket?

Re: Wicket tests are extremely slow

[James Selvakumar]

Hi all,

Thank you very much for all the suggestions.
I agree that the slowness is because of Spring context initialized multiple
times.
Ours is a multi module maven application and what I have seen is the
context being initialized at least once per module because of new beans in
every module.
The ApplicationContextMock concept looks interesting and I shall try that
out.
Thanks again for taking your time to help me. Wicket rocks!

Wicket tests are extremely slow

[James Selvakumar]

Hi,

We have a Wicket 7.x application which uses a Spring/Hibernate backend. We
have few hundred simple Wicket tests that basically tests whether the page
has been loaded properly. Since almost all our Wicket pages use Spring
beans, we have to initialize the Spring application context for our Wicket
tests to run. And as a result our tests are extremely slow that we have
stopped running them in our main pipeline.

What strategy do you all follow to run Wicket tests that can run fast?

Thanks in advance,
James

Re: DCEVM and Hotswap agent support

[James Selvakumar]

Dear all,

Just to complete this loop, I've managed to configure my multi module
Wicket application to reload classes and resources (e.g html, property
files) without restarting the whole application using DCEVM + HotSwapAgent.
After following the standard procedures in configuring these two tools, all
you need to do is to have a property file named "hotswap-agent.properties"
in your web application's classpath and configure the "extraClasspath"
property in it.
If anyone is interested, please take a look at this gist
 for a
sample configuration.

Re: Embedding HTML report generated by JasperReports in a Panel

[James Selvakumar]

Hi Ernesto,

I'm not sure about that but they do support SVG images which really have
simplified things.
Since there is just a single html file now, I'm just embedding it inside a
Panel.
But anyhow, this exercise helped me to learn about mounting a folder with
the file name as a param and how to use an iframe within Wicket. I had no
idea about these things before.
I'm really excited by the support offered by the community.
Thank you once again guys.

Hi Martin,

But the reports are generated dynamically. Is it possible to mount a

Re: Embedding HTML report generated by JasperReports in a Panel

Hi,

I'm trying something weird like this and it's not working.

HTML:


Java:
WebMarkupContainer container = new WebMarkupContainer("myFrame");
container.add(new AttributeAppender("src",
Model.of(reportFile.getPath(;

What's the correct way to do this?

Embedding HTML report generated by JasperReports in a Panel

[James Selvakumar]

Hi all,

I'm trying to embed the HTML report from the filesystem generated by
JasperReports in a Panel.

I tried using a WebComponent and write the content of the HTML file to the
Response. The markup gets added as expected but unfortunately JasperReports
produces separate image files and I'm not sure how to display them.

Is it possible to display HTML from filesystem along with it's dependant
resources inside a Wicket component?  Or is there a better way?

Re: The day Wicket became Apache Wicket 10 years ago!

[James Selvakumar]

It's heartening to see Wicket still going strong.
And I take this opportunity to thank all of you for this amazing framework
and many thanks for the support offered.
The support offered by the Wicket community is superior compared to even
commercial products.
Keep going!

Analytics for Wicket applications

[James Selvakumar]

Dear community,

Though this is not a question related to the Wicket framework which we have
been using happily for nearly 6 years, I hope the community would help me
with it's insights regarding providing analytics in Wicket applications.

We are using the excellent wicked-charts library (HighCharts) to provide
home grown analytics in our application. I've been wondering recently
whether we are going in the right direction.

How do you all provide analytics in your applications? Are you integrating
some third party BI tools like JasperSoft or Pentaho? Or are you building
it on your own?

Thank you very much in advance.

Re: Unable to retrieve row model in DataTable while running the application in Jetty

[James Selvakumar]

Hi Francois,

Thank you very much for your reply.
I define my datatable like this:

StandardDataTable dataTable = new StandardDataTable("dataTable",
columns, this.getDataProvider());

And that's the only place I use a data provider.

I don't override it's model.

In my data provider I don't call detach.

Unable to retrieve row model in DataTable while running the application in Jetty

[James Selvakumar]

Hi all,

I have a DataTable with some ajax links in the first column. Other columns
are simple property columns. The ajax links are used to edit/delete
associated entities. The ajax links are encapsulated inside a panel.

The DataTable itself is rendered fine.

The problem I face is that the rowModel.getObject() is null when any of the
ajax link is clicked when running the application in Jetty (Maven jetty
plugin).  However, if the application is deployed on Tomcat, everything
works as expected.

Can anyone highlight my mistake, if any here?

Here's how my code looks like:

List columns = new ArrayList();
columns.add(new AbstractColumn(Model.of(getString("name")), "name")
{
@Override
public void populateItem(Item cellItem,
String componentId, final IModel rowModel)
{
cellItem.add(new DataTableActionPanel(componentId,
rowModel.getObject().getName())
{
@Override
protected void onEdit(AjaxRequestTarget target)
{
LOGGER.debug("Editing {}", rowModel.getObject());

//proceed to display another panel to edit the entity

}

@Override
protected void onDelete(AjaxRequestTarget target)
{
LOGGER.debug("Deleting {}", rowModel.getObject());

//proceed to delete the entity

}

});
}
});

//add other columns


//add the columns to a data table

Dynamic datatable columns (sequel)

[James Selvakumar]

Hi all,

I want to render a datatable with dynamically different columns based on
user input (via a DropDownChoice) over ajax.
I came across this old post

which mentions that this feature might be available in Wicket 1.4.
Is this feature available in Wicket now?
Can someone explain me how to achieve this?

Can @Inject annotation be used instead of @SpringBean to inject Spring beans?

[James Selvakumar]

Hi all,

I've always used @SpringBean annotation to inject Spring beans in my Wicket
components.
We found that we could also use the standard @Inject annotation in Wicket
components.
Is it advisable to use @Inject instead of @SpringBean?
Or should we continue to use @SpringBean?

Re: Error while calling Wicket from a JavaScript function

[James Selvakumar]

Hi Martin,

Is it possible to return a value from the ajax behavior while responding to
the ajax call?
I'm trying to do something like this in the server side:

target.appendJavaScript("foo");
>

And then try to use it in my JavaScript:

var foo = Wicket.Ajax.get({ u: window.callbackUrl });
> //do some processing with foo
>

Is this valid? Or is there a better way?

Thanks a lot Martin. You're right. I had something else in my code and
after I fixed it, I managed to make a ajax call from JavaScript.

Error while calling Wicket from a JavaScript function

[James Selvakumar]

Dear Wicket team,

I need to make a call to a Wicket page from my JavaScript function.
I followed the guide Calling Wicket from Javascript

and managed to define an ajax behavior to respond to the JavaScript call.

My ajax behavior looks like this:

> private final AbstractDefaultAjaxBehavior behave = new 
> AbstractDefaultAjaxBehavior()
> {
> protected void respond(final AjaxRequestTarget target)
> {
> LOGGER.debug("Received a request from client to get the encryption 
> key");
> target.add(new Label("foo", "Yeah I was just called from 
> Javascript!"));
> }
>
> public void renderHead(Component component, IHeaderResponse response)
> {
> super.renderHead(component, response);
> String callbackUrl = getCallbackUrl().toString();
> response.render(JavaScriptHeaderItem.forScript("var callbackUrl='" + 
> callbackUrl + "';", "values"));
> }
> };
>
> This callback url got rendered in the page like this:


> /* var callbackUrl='./wicket/page?0-1.IBehaviorListener.0-';
> /*]]>*/
> 
>


And here is my JavaScript code:

> var wcall = Wicket.Ajax.get({ u: '${callbackUrl}'});
> alert(wcall);
>
> But I'm getting the following error in the Wicket Ajax Debug Window:

*An error occurred while executing Ajax request:TypeError: a is undefined*

Can someone point out what's the mistake here?

Re: Encrypt selected form data before submitting the request to Server

[James Selvakumar]

Hi Rob,

Thanks for taking time to reply. And many thanks for the detailed example.
Yes, having the secret rendered makes this approach questionable while
using encryption.
But what you've shared will be sufficient if one were to use other
techniques like hashing etc.

Encrypt selected form data before submitting the request to Server

[James Selvakumar]

Hi all,

I have this requirement where some of the data entered by the user are to
be encrypted in the client side before the request is submitted to the
Wicket server even though the communication is over HTTPS.

I am thinking of having some JavaScript code in the client which shall
intercept the form submission, request the Server for a randomly generated
key and encrypt the form data using the key received and then submit the
form again.

Any idea how to achieve this in Wicket?

Thanks for your reply.
Maybe I'll look into it. But it'll be great if there is standard support

Re: Reload Wicket classes/markup without reloading Servlet Container

[James Selvakumar]

Dear friends,

Thank you very much for your suggestions.
I was using JRebel before but was fed up with the frequent change in their
licensing module.
I don't think Jetty can reload classes in a multi module Maven project? Can
it?
Has anyone used DCEVM successfully in a multi module Maven project?
Thanks for mentioning about Stage Monitor, but is it related to what we are
discussing? Looks more like a performance monitoring app to me. Please
correct me if my understanding is wrong.

 panel1DropDownChoice and found that feedback messages are indeed
 generated.

 However from the debug messages in my behavior, I found that feedback
 messages were some how lost.

 This is the behavior I'm using. (Thanks London Wicket users)

 *public class ValidationMsgBehavior extends Behavior

 {
  private static Logger logger =
 LoggerFactory.getLogger(**ValidationMsgBehavior.class);

  @Override
  public void afterRender(Component c)
  {
  logger.debug(Preparing to add validation msg for the component
 {}, c);
  FormComponent fc = (FormComponent) c;
  if (!fc.isValid()) {
  String error;
  if (fc.hasFeedbackMessage()) {
  logger.debug(Form component {} has feedback messages,
 fc);
  error =
 fc.getFeedbackMessages().**first(FeedbackMessage.ERROR).**
 getMessage().toString();
  } else {
  error = Your input is invalid.;
  }
  fc.getResponse().write(
  div class=\text-error\ + error + /div);
  }else{
  logger.debug(Form component {} is valid, fc);
  }
  }
 }*

 Any clues? I've been trying to crack this for a whole day.

Re: How to build a hudson/jenkins like live log viewer?

[James Selvakumar]

Guys,

This works like a charm. I'm using it in in our project. Thanks once again
for all your suggestions.
Just a minor correction in case you are using a MultiLineLabel for
nextLog. 
While appending Javascript in the onPostProcessTarget method, instead of:



use:



This is needed because .text() method removes the html formatting (i.e the
br tags) added by MultiLineLabel.
Cheers.

Re: wicket-6 User friendly form validation with Wicket (stuq)

[James Selvakumar]

Hi all,

We have been using the examples given in the FormsWithFlair for a while
and it has been working very well.
However, we recently migrated from wicket 1.5.x to 6.3.0 and the code
didn't compile because of some api changes.

Here's the code that worked in 1.5.x
pre
public class ValidationMsgBehavior extends AbstractBehavior
{
@Override
public void onRendered(Component c)
{
FormComponent fc = (FormComponent) c;
if (!fc.isValid()) {
String error;
if (fc.hasFeedbackMessage()) {
error = fc.getFeedbackMessage().getMessage().toString();
} else {
error = Your input is invalid.;
}
fc.getResponse().write(
div class=\validationErrorMessage\ + error +
/div);
}
}
}
/pre

Am I right to say that I can replace AbstractBehavior with Behavior?
But I'm not sure what will be the best way to handle the feedback messages
related code.
Is a call to hasFeedbackMessage() correct now or should we use a feedback
collector here?
getFeedbackMessage() has been removed so I have no choice but to use
feedback collector to get it.

Re: highlight invalid fields with custom Validation Framework?

[James Selvakumar]

Martin,

Thank you so much. I was exactly in the position where delta458 was and
almost got through with it.
After following your suggestions, the ValidationMsgBehavior looks like this:

pre
public class ValidationMsgBehavior extends Behavior
{
@Override
public void onRendered(Component c)
{
FormComponent fc = (FormComponent) c;
if (!fc.isValid()) {
String error;
if (fc.hasFeedbackMessage()) {
error =
fc.getFeedbackMessages().first(FeedbackMessage.ERROR).toString();
} else {
error = Your input is invalid.;
}
fc.getResponse().write(
div class=\validationErrorMessage\ + error +
/div);
}
}
}
/pre

I'm using Wicket 6.3.0 and there is no onRendered method in Behavior.
I should be using afterRender(Component component) now, right?
That will make this code compatible with the latest wicket version.

  Hi Martin,
  thanks so much for the replies... almost done, some little questions
 still
  there.. I got it working, could you verify that its right what I made? :)
 
  1)
  *//Had Error: Wrong number of type arguments, required 2 - It works when
 I
  do  IVisitorComponent,Void ;-)

 Trust the compiler and follow his recommendations ;-)

  public class ShinyFormVisitor implements
 IVisitorComponent,Serializable {*
 
  Set visited = new HashSet();
 
  public void component(final Component c, final IVisitVoid visit
  /*[2]*/) {
  if (!visited.contains(c)) {
  visited.add(c);
  c.add(new RequiredBorder());
  c.add(new ValidationMsgBehavior());
  c.add(new ErrorHighlightBehavior());
  }
  }
 
  ...
 
  private class ValidationMsgBehavior extends Behavior {
 
  public void onRendered(Component c) {
  FormComponent fc = (FormComponent) c;
  if (!fc.isValid()) {
  String error;
  if (fc.hasFeedbackMessage()) {
* //Had error, now working with this.. thats right?
  error =
  fc.getFeedbackMessages().first().getLevelAsString();*

 fc.getFeedbackMessages().first(FeedbackMessage.LEVEL_ERROR).toString();

 Or you may use the default registered converter to transform it to
 String. But this is more advanced and most probably you don't need it.

 
  } else {
  error = Your input is invalid.;
  }
  fc.getResponse().write(
  div class=\validationMsg\ + error +
 /div);
  }
  }
  }
  }
 
 
  2) Do you know any good wicket tutorials/example where I can learn how to
  work with customized FeedbackMessages?

 The source code is the best. It is really simple.
 Check
 https://github.com/apache/wicket/blob/master/wicket-core/src/main/java/org/apache/wicket/markup/html/panel/FeedbackPanel.java

 
  thanks..

Re: Wicket page test

[James Selvakumar]

Sorry if this is asked previously. Is it advisable to use a shared wicket
tester across multiple unit tests?

 It depends where WicketTester is initialized.

Hai,
   
Here we are using wicket 1.5.7.
   
We have a simple test for each wicket page to assert rendering like
  this:
   
WicketTester.assertRenderedPage(Page.class);
   
In our module we have 52 tests w.r.t wicket pages.
   
It takes so long to run these tests.
   
Please give suggestion to improve test cases that how to reduce the
  time
taken by this module.
