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?

Re: data persistence using hibernate

[James Pollard]

I don't need hibernates added level of abstraction

I was taught in the past to do database connectivity using jdbc 
drivers/connectors, hikaricp just takes this a step further
by providing a pool of connections to use. Basically I've looked at orm 
frameworks in the past and just couldn't get my
head around how to use it, I much prefer spelling out my query exactly 
myself.

HikariCP is a just a connection pool.
I am not sure what exactly you mean with "instead". A connection pool is
not a replacement of an ORM framework like Hibernate.




However, I can't workout where the most appropriate place to put the
connection pool close call, is there a close or shutdown function
I can override so that the connection pool can be closed cleanly. I
haven't had any luck in my search so far

Additionally, I keep running into the following error:
  java.lang.IllegalStateException: Illegal access: this web
application instance has been stopped already.
 Could not load [META-INF/services/org.mariadb.jdbc.plugin.Codec].
The following stack trace is thrown for debugging purposes as well as to
 attempt to terminate the thread which caused the illegal access.

I'm assuming this is a error more to do hikaricp so I'll enquire among
their community about it, but if someone has encountered this before feel
to volunteer any suggestions or recommended actions. The odd thing is I
still seem to be able to send queries to the database from what I can
tell

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?

Ancestor controller patterns?

[James Carman]

I have a scenario where a certain type of component should typically be
invisible, but in certain scenarios, it neeeds to become visible. That
visibility can be changed by anybody in its ancestry and the closest one to
the component should decide.  Anyway, do we have established patterns for
this?  Do I make the guys who want to control this visibility implement
some interface and search for them up the hierarchy?  Is there a different
way?

Thanks,

James

ListView Add/Remove via AJAX...

[James Carman]

It has been a while since I've used Wicket and man, I really forgot how
much I love this framework! It may be that I'm rusty, but I've searched
quite a bit and tried all the suggestions I've found, but I can't seem to
make add/remove via AJAX work for a ListView while preserving the input
data. I am using Wicket 8.0.0-M9. Here's what I've done so far:

correctChoiceGroup = new CheckGroup<>("correctChoices",
Model.ofSet(Sets.newHashSet()));
correctChoiceGroup.setRequired(true);
correctChoiceGroup.setOutputMarkupId(true);
correctChoiceGroup.setRenderBodyOnly(false);

final IModel<List> choicesModel = Model.ofList(new LinkedList<>());
choicesView = new ListView("choices", choicesModel) {
@Override
protected void populateItem(ListItem item) {
final int index = item.getIndex();

item.add(new TextField<>("field", item.getModel()));
item.add(new Check<>("check", Model.of(index)));

final AjaxSubmitLink deleteLink = new AjaxSubmitLink("deleteButton") {
@Override
@SuppressWarnings("unchecked")
protected void onSubmit(AjaxRequestTarget target) {
final ListView listView = findParent(ListView.class);
listView.getModelObject().remove(index);
listView.removeAll();
target.add(correctChoiceGroup);
}
};
deleteLink.setDefaultFormProcessing(false);
item.add(deleteLink);
}
}.setReuseItems(true);


correctChoiceGroup.add(choicesView);

add(new AjaxSubmitLink("addButton") {
@Override
protected void onSubmit(AjaxRequestTarget target) {
choicesView.getModelObject().add("");
choicesView.removeAll();
target.add(correctChoiceGroup);
}
}.setDefaultFormProcessing(false));

add(correctChoiceGroup);


When I click on the delete link (I have a similarly-implemented "add" link
outside of the ListView), all of the input data goes away, since I am
losing the original items from the removeAll() call.  Now, I am doing the
removeAll() to force Wicket to realize that I've changed the underlying
list, otherwise, the original items are reused and the it always looks like
the last item is removed.  I'm sure I'm just rusty, but I am banging my
head on this one.

Thanks,

James

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,

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.

Re: Embedding HTML report generated by JasperReports in a Panel

[James Selvakumar]

Hi Martin,

Should I mount just the base dir where all my reports shall be generated
and refer it elsewhere?

Re: Embedding HTML report generated by JasperReports in a Panel

Hi Martin,

But the reports are generated dynamically. Is it possible to mount a
resource from within a panel?

Re: Embedding HTML report generated by JasperReports in a Panel

[James Selvakumar]

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<FooEntity,
String>(Model.of(getString("name")), "name")
{
@Override
public void populateItem(Item<ICellPopulator> 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
<http://apache-wicket.1842946.n4.nabble.com/Dynamic-DataTable-columns-td1856733.html>
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?

Re: Error while calling Wicket from a JavaScript function

[James Selvakumar]

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
<https://cwiki.apache.org/confluence/display/WICKET/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

>
> This callback url got rendered in the page like this:

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?

Dear friends,

I want to upload a file using REST API.
I'm already using WicketStuff REST library.

Re: Reload Wicket classes/markup without reloading Servlet Container

Thanks Martin. Will try that out.
I assume Jetty + DCEVM can reload Spring beans as well.

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.

Re: Event listeners not working after Javascript actions

[EC James]

Thanks for the clone idea, however it seems that AjaxButton cannot be cloned.
I did try a similar idea,
where I define the tab content outside of the tab, and only move it into the
tab using '.replaceWith'
when the page is fully loaded.  This works but makes for some ugly
transitions.

The tabbed interface is a third party plugin, and I don't know why it is
re-rendering the content. I will 
have to look into that.

It would be nice if I could decide when the events are loaded instead of on
'domready', but I don't see 
any easy way to do that.

Event listeners not working after Javascript actions

[EC James]

I have a page with a Tabbed interface(not wicket) that performs actions
before and after the domready signal.

It has it's own signal for when it is complete:
$( document ).on( "wb-ready.wb", function( event ) {
//The page is fully loaded now.
}

The rendering order is like this:
1) Tab 1 rendered
2) Page loaded (domready)
3) Tab 1 rendered
4) Done loading (wb-ready.wb)

I have an AjaxButton in Tab 1 that does not work. It works fine outside the
tab.

I'm guessing that something is happening in the 3rd stage that removes the
event listener.

As a test, if I take the following from the header and put it in the
"wb-ready.wb" all is good. Of course this only
works as a test as I have to manually change the url.
/**/

I have no idea how to fix this. All I can imagine is:
1) Somehow rerunning Wicket.Event.add after "wb-ready.wb", or
2) Moving Wicket.Event.add out of the head and into "wb-ready.wb", which I
don't think is possible.

Any ideas on how to reregister the event listener for the button?

custom authentication/authorization without Spring

[Parker, James]

I'm looking for a way to create custom authentication and authorization without 
the use of additional libraries such as Spring.  Our current need is to look 
for a portal authentication cookie and validate it, then search a database for 
what the user is authorized to do.  If validation fails, we need to forward the 
user on to our application portal.

Of course as soon as I get this working, there is a high likelihood we will 
change our authentication to a different system, so I need to keep it 
straight-forward and simple.  Nothing here is so important that we need high 
level security and hack prevention with the authentication.

There is no username and password, only a cookie (single sign on from our 
portal), and no login page sense our portal handles it all.  Can someone point 
me in the right direction?  Either point me to a class/interface or to a 
book/website.  Worst case scenario, I create a filter that upon passing 
authentication will pass processing onto Wicket's default filter.  Of course 
kludge something together for authorization.

All assistance is appreciated.

Jim

 *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.

 Hi,

 Now migrating a working project from wicket version 1.4 to 6.4.
 I have a text field that uses the following behaviors:
 A.  AjaxFormComponentUpdatingBehavior(onchange);
 B.  AutoCompleteBehavior; and
 C.  AjaxFormComponentUpdatingBehavior(onkeypress).

 Say I enter an letter 'U' into the text field, and an auto-suggest list
 pops up.

 There are 2 problems which is not seen in wicket 1.4:
 1) When I select an item (e.g. USD) from the auto-suggest list using a
 mouse, the onchange event from behavior A  is fired twice. The 1st
 onchange event is for 'U' and the 2nd onchange event is for 'USD'.
 Can I prevent the 1st onchange event from happening?

 2) When I select an item (e.g. USD) from the auto-suggest list using
 the
 Enter keypress, an onkeypress event is fired by behavior C. Can I
 prevent
 this onkeypress event from happening?

 Regards,
 James

Re: find html tag

[james yong]

Hi Michael,

What you need may not be related to wicket directly.
I suggest you can attach a javascript 'click' handler that will get the
parent and modify the attributes.
If you are using jQuery, you can use the parent function i.e. 
http://api.jquery.com/parent/ http://api.jquery.com/parent/  

Regards,
James

 Ok, so you are indeed looking for a way to change a html attribute ;-)

 Since you wrote (in your folluw-up e-mail) that you cannot generate the
 html, there are some ways, but they mostly work outside of the normal
 wicket way.

 1) In the component which actually renders your static html override
 onComponentTagBody and fiddle with the markup stream (e.g. look at
 replaceComponentTagBody)

 2) store the static html somewhere by itself, and create a custom model.
 The model can then load the html and perform string replacement.
 You can then add a label component which uses the model and has
 setEscapeModelStrings(false) set.

 What you want to accomplish (e.g. changing some html attributes) can
 be done by adding an attributemodifier to each

 In pseudocode:

 RepeatingView uls = ...

 WebMarkupContainer li = ...
 uls.add(li);

 now, you can do something like this:
 li.add(new AttributeAppender(...) {
  isEnabled() {
  return true if you want to append a html attribute;
  }
 });

 Or alternatively:

 WebMarkupContainer li = new WMC() {
  onComponentTag(ComponentTag tag) {
  super(tag);

  tag.put(my-html-attribute, value);

updateAjaxAttributes has no effect on AutoCompleteBehavior

Hi all,

Just to confirm if overriding updateAjaxAttributes has any effect on

I was tryng to do the following but see no popup nor code reflected in the

@Override

attributes) {
super.updateAjaxAttributes(attributes);
AjaxCallListener myAjaxCallListener = new AjaxCallListener() {

@Override 
public CharSequence getBeforeHandler(Component component) { 
return alert('I\'m executed before the firing of the
Ajax call'); 
}
};
ListIAjaxCallListener list =

Re: updateAjaxAttributes has no effect on AutoCompleteBehavior

[james yong]

Hi Martin,

I tried again with a simple application and pretty sure updateAjaxAttributes
has no effect on AutoCompleteBehavior. But then, I need to verify with
another party to verify/confirm whether this is a bug or intended feature.
It is working with AjaxFormComponentUpdatingBehavior.

Regards,
James


Martin Grigorov-4 wrote
 Hi,
 
 I don't see why it should not work.
 Actually AutoCompleteBehavior itself wont work without this method. It
 overrides it to do:
 attributes.setWicketAjaxResponse(false);
  attributes.setDataType(html);

Clearing Browser Cookies

[Corbin, James]

This is a rehash of a previous discussion on this forum relating to immediate 
removal of a browser cookie.

I have a list view that displays data loaded from 1 or more browser cookies.  
On this panel I also have a clear action (Link) that when clicked deletes the 
cookies.  The underlying list view model is detached which forces (verified) 
the cookies to be re-read.

The problem is that when I re-read them after deleting them from the response, 
they are still present.  If I then execute the clear action again, the list 
view is refreshed again and the cookies are no longer present.

I'm not sure what is going on here.  Are they being cached, is it a timing 
issue?  Why on the second clear action does it finally indicate the cookies 
have been removed.

My immediate need is to be able to delete the cookies, refresh the list view, 
and see that they are no longer present (no data rows in list view).

ClassCastException (WebResponse)

[Corbin, James]

I have the following code that is generating a ClassCastException that I do not 
fully understand,


(WebResponse)RequestCycle.get().getResponse();


The actual type of the value returned is 
org.apache.wicket.ajax.AbstractAjaxResponse$AjaxResponse.


I'm trying to understand why this call returns an AjaxResponse instead of a 
WebResponse, in my case.  I don't believe the code where this code get executed 
is in the context of Ajax.


J.D.

Re: ClassCastException (WebResponse)

[Corbin, James]

Yeah, it is.  The action was triggered via an AjaxLink which I didn't
realize at the time.  Is there a way to get access to the WebResponse in
this scenario?  I need to delete a cookie, but obviously, you cannot do so
through an AjaxResponse.

J.D.

Most likely because it is an Ajax response... :)

Do you have the AjaxIndicator somewhere on your page and does it indicate
an
Ajax request cycle happening?
What about while in DEVELOPMENT mode, can you monitor the page activity
using the Wicket Ajax Debug Window?

FYI, while in DEVELOPMENT mode you might want to add the DebugBar to your
page as well.

Deleting Cookies

[Corbin, James]

I have a ListView that renders items that are populated from user cookie data.  
The ListView contains a clear action that is supposed to delete the cookies 
then refresh the ListView so it reflects that the cookie data was removed.  I 
have code that executes the deletion of the cookies (works), then I turn around 
and detach the ListView's model which triggers a rereading of the cookie data.  
For some reason (probably works as designed), when the model is detach and 
reloads the cookies, they are still present.
If I then force a page refresh, cookie data is in fact removed and the ListView 
is empty.

Is there a way to attain this?  Am I missing something?  I really don't want to 
have to reload the page to see that the cookie data has been removed.

J.D.

Re: Deleting Cookies

[Corbin, James]

The ListView is not in a form, which is why I am leaving the default for
setReuseItems to false.
I am using a LoadableDetachableModel and verified the load that rereads
the cookies, does in fact get called after I delete them (reset method
call below).  If I break in the load of the detachable model, it is
reading that there are still values for the cookies I deleted in the
previous step.

Basically, here is the body of my Ajax Link's onClick,

RecentlyViewedItemsCollection c = new
RecentlyViewedItemsCollection(util.getCurrentUser());
c.reset(); // this actually deletes all the 
cookies
getModel().detach(); // this forces the 
detachable model to call its
load, which attempts to re-read specific cookies that should no longer
exist

target.add(RecentlyViewedItemsPanel.this.get(itemContainer)); //
lastly, I refresh the parent (WebMarkupContainer) of the ListView

I would have expected that when the model's load method is called that it
would see that the cookies were removed, but it still finds them.

J.D.

Re: Deleting Cookies

[Corbin, James]

Hi Sebastian,

Thanks for your feedback.  I wasn't recreating (semantics?) the Listview,
I was just refreshing it via ajax so it updates with the model changes.
What do you mean by reattach the listview's parent-container?  Do you
mean remove the listview and re-add it in the onbeforerender?

J.D.



On 12/6/12 4:16 PM, Sebastien seb...@gmail.com wrote:

Well, I think it is because this is the same listview that is redisplayed,
not the new one.
The cause is that you did not add the new listview to its parent.

But, I would have done a little bit differently because:
1/ You do not have to recreate the listview in ajaxlink's onclick. just
clear cookies and reattach the listview's parent-container
2/ You do not have - generally speaking - to detach you model yourself
and,
moreover, it is not interesting to do it in the same request cycle. It
should be end at the end of the previous cycle. The use of a LDM does this
for you.

So: just one ListView with a LDM, and it should be good.
If it's still not, maybe the persistence of the cookie update is a little
bit slow and IO-async... But I (means myself) could not help in a such
case.

Best regards,
Sebastien.

Wicket 6 Ajax Behaviors

[Corbin, James]

I have some older javascript code that I am migrating to work with Wicket 6 and 
not sure how to do so.

I had some javascript that was triggering the onclick of an element in the 
following way,

somedomeelement.click();  // post wicket 1.4 this causes error - TypeError: 
Property 'onclick' of object #HTMLTableRowElement is not a function.

Post wicket 6 (1.5?) this will not work because of how wicket no longer 
produces the onclick attribute and instead uses event registration.

So, my question, how do I need to modify my javascript to be able to trigger 
the click event, because elem.click(); doesn't work.

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.

 Or you may use the default registered converter to transform it to

  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

Convert bookmarkable url to wicket relative url?

[Corbin, James]

I need some help with converting a bookmarkable url into a wicket relative url.

My intent is to persist the url convert it to a wicket relative url and then 
redirect to that relative url.

I am using Component.urlFor(Class, PageParameters) api to generate the 
bookmarkable url.

Some interesting points about this problem is that I am using Wicket 6.0 , and 
Encrypting the URLs (using CryptoMapper).

The url format that comes back from the urlFor API, in my case, is as follows:

generatedUrlString = ./bookmarkable/path to some wicket page?x=FWzgyImodAY

I've tried the following to generate a wicket relative URL,


Url url = Url.parse(generatedUrlString);

String url2 = RequestCycle.get().getUrlRenderer().renderRelativeUrl(url);


This comes close, generating a URI, like,


protocol://host:port/wicket/wicket/bookmarkable/some wicket page?x



Notice that the parameter is chopped off.


Is there way to achieve a wicket relative url from a bookmarkable url with 
encrypted parameters?


Thanks,

J.D.

Detecting HTML 5 Features in Wicket

'getBatherExtendedBrowserInfo()' really just builds a small page to test
client side settings which posts back the information it's gathered. That
page is provided from 'newBrowserInfoPage()' in WebSession.

Thus, if you want to plug Modernizr into your session before the page
load, you can override this method and provide a custom page which
includes Modernizr. Three things to note about this approach. First, you
should probably start with just extending the 'BrowserInfoPage' class to
get it's built in postback functionality. Second, this callback doesn't
trigger until you call 'WebSession.getClientInfo()' for the first time,
so make sure that's done before any heavy lifting. Finally, I would
suggest embedding Modernizr onto your new page directly instead of
linking a JS file. This is mainly to reduce latency overhead from
multiple requests.

Re: [Announce] wicket-dashboard

[James Eliyezar]

Managed to get the demo working. It's really elegant.
Echoing the same feelings as Paul.
It would be nice to split this up into relevant modules.

While I was playing around with the code, I thought of creating a custom
widget with just a data table.
So I created the following classes:

   - TableWidget
   - TableWidgetView
   - TableWidgetDescriptor

Now what should be in TableWidget and what should be in TableWidgetView?

Should I expose the data provider and columns separately from TableWidget?

 Hi,

 I will be adding your dashboard to one of my projects - this is a matter of
 weeks (customer is really, really excited ;)). I have some suggestions, I
 would divide the project into seperate modules:

 - wicket-dashboard-core: module with dashboard itself, simply juest the
 component and needed interfaces (jar as an output)
 - wicket-dashboard-widgets: module were some standard widgets would be
 implemented (jar as an output)
 - wicket-dashboard-demo: module with demo useage (war as an output)

 This way to use dashboard one must simply add wicket-dashboard-core as
 dependency. He can now develop his own widgets or use standard widgets. To
 use standard widgets, he must also add wicket-dashboard-widgets as
 dependency to his project.

 What do you think about it?

Re: [Announce] wicket-dashboard

[James Eliyezar]

This is a very good news. Will be using this right away!

I have a small problem guys, definitely something is wrong with my setup
(I'm using nexus).
I get this exception when I try to build the project.

No versions available for
 org.codehaus.jackson:jackson-mapper-asl:jar:[1.8,1.8.6],[1.9,1.9.7] within
 specified range


But there indeed is a jackson-mapper-asl jar in my nexus. What's wrong here?

Re: AjaxEditableLabel Issue (Application in Production Mode)

[Corbin, James]

Hi Martin,

Thanks for the feedback.  What is a bit confusing to me is how the
behavior changes when running wicket in Production Mode (doesn't work) vs.
Development Mode (works).  I don't see why the wicket application mode
would cause this behavior to change.

In our situation the AjaxEditableLabel component is nested in a table cell
and the table itself is parented by a Form.

I will look for JS errors as you suggest.

Thanks,
J.D.







On 9/26/12 12:59 AM, Martin Grigorov mgrigo...@apache.org wrote:

Hi,

It sounds like a JavaScript related problem.
It could be that there is blocked Ajax channel and the click cannot
make it to the server. Or something similar happened once, this leaded
to different state at the server and the client and since then it
cannot re-synchronizes the states.

Reload the page and look for JavaScript errors.
In Firebug do: Wicket.Log.error = function(text) {console.log(text);}

 The only behavior that is being overridden on the AjaxEditableLabel

 I searched the forums and google and could not find anything that would
explain the different behavior of this component when the application

 Interesting enough, the AjaxEditableLabel does work fine in Production

 Not sure if that has anything whatsoever to do with this issue.

 Ideas?

Re: Datepicker with range selection support

 Hi Sebastien.

 wicket-jquery-ui has the goal to integrate jQuery UI widgets as Wicket
 components; but it's also designed to integrate (easily, I guess) any
 jQuery plugins (that's what I tend to evince in the tutorial series...).

 So, I played around with the fox-run-software (range-)date-picker... I
 noticed that the (kind-of) drop-down box which displays the date-picker is
 not shipped in the library and should therefore be achieved out of the
 box,
 as stated here:
 http://www.foxrunsoftware.net/**articles/javascript/date-**
 range-picker-similar-to-**google-analytics/http://www.foxrunsoftware.net/articles/javascript/date-range-picker-similar-to-google-analytics/

 Given this, I did integrate two components (for both Wicket 1.5.8  Wicket
 6.0.0):
 The first one is a RangeDatePicker, which is designed - when used alone -
 to be an 'inline' widget, with an ajax behavior triggered on 'change'
 event. This component can serves as base for more complex component, like
 a
 google-analytics-date-picker..**.. (you will notice that the change
 event is
 triggered on every date click... A merge request - that provide an
 'onRangeChanged' event - is in stand-by since a month and has therefore
 not
 been merged yet). The second component relies on this first one and on a
 TextField to make the RangeDatePickerTextField (which indeed is a
 FormComponent). It should be closed to the component you are looking
 for...

 http://www.7thweb.net/wicket-**jquery-ui/plugins/datepicker/**
 RangeDatePickerTextFieldPagehttp://www.7thweb.net/wicket-jquery-ui/plugins/datepicker/RangeDatePickerTextFieldPage

 If it fits your needs, you can either use it (released as
 com.googlecode.wicket-jquery-**ui:jquery-ui-plugin:1.2.3-**SNAPSHOT) or
 have a
 look at github project to see how it works. Sure, do not hesitate to have
 a
 look at the other integrations as well (wicket-select2 is a prime example,
 and the other jQuery integrations too).

 If you have any questions, do not hesitate to use the forum (you may find
 the link on the demo site's homepage)

 Best regards,
 Sebastien.

  Well,

 If you make a tutorial about creating a plugin using wicket-jquery-ui,
 even though it'll be for wicket 6, it should be relatively simply
 adaptable
 to do the same for wicket 1.5 (unless there's a huge lot of changes
 between
 the two for wicket-jquery-ui which is quite possible considering wicket 6
 comes with jquery support unlike 1.5).

 I'll take a look at your current how tos for wicket-jquery-ui (we don't
 use wicket-jquery-ui for the moment - we have a few components using
 wiquery and a couple very old components using jquery-ui in a crappy
 way),
 but that's always interesting to see what's out there and how it works.

 I'll take a closer look on wicket-select2 as well, as I suppose it could
 be a good inspiration to integrate the fox run software datepicker
 library
 (which is not using jquery-ui).

 Sébastien

Using a div/span tags for wicket components

[Corbin, James]

I'm sure this subject has been discussed before many times, but would like to 
revisit it to get some thoughts from the community.

Consider a Wicket TextField.  The typical markup is something like,

input type=text wicket:id=someId …/

I would like to, instead, specify a span or a div in the markup and bind the 
TextField to that markup instead.

I know I can achieve this by creating a new class that extends Panel (call it 
TextFieldPanel) with markup similar to the following,

…
wicket:panel
input type=text wicket:id=someId/
/wicket:panel

Now I can use a div or span tag as in,

div wicket:id=editor/

The problem with this approach is now if I want to affect some portion of the 
TextField, like adding a behavior to it, I'm almost forced to expose internal 
details about the Panel impl that I shouldn't.

For example, myTextFieldPanel.addBehaviorToChildComponent(IBehavior… behavior) 
which then adds the behavior to the TextField within the derived Panel.

It would be nice to be able to do something like,

public  class MyTextFieldT extends TextFieldT {…}

That allows you to use a span or a div for the markup but generates valid 
HTML.  With this approach you would be less inclined to expose the internals of 
the implementation because you are operating on an actual TextField instance.

I am using a fairly old version of Wicket, 1.4.13 but in the process of 
upgrading to 6.0.  So I would like some thoughts on if this is feasible for 
1.4.x and if its even practical.  I realize I have control over the 
construction of the markup for a component but I'm concerned as well about 
making sure the generated markup is valid HTML.

Thanks,
J.D.
