Re: Migration 1.4 -> 7.0: org.apache.wicket.markup.html.link.PageLink

[Sébastien Gautrin]

Hi Martin,

I just noted something while writing my answer to this thread: the link 
on http://wicket.apache.org/learn/#guide for Wicket 6 migration guide is 
broken, or rather the redirection of http://s.apache.org/wicket6migrate 
is broken: it leads to 
https://cwiki.apache.org/confluence/display/WICKET/Migrating+to+Wicket+6.0 
when the actual migration guide is at 
https://cwiki.apache.org/confluence/display/WICKET/Migration+to+Wicket+6.0

Hi,

The easy fix is: use BookmarkablePageLink.

The class has been deprecated for 1.5 and removed for 6.x, I think.
I will be easier for you if you upgrade from 1.4 to 1.5, then to 6.x and
finally to 7.0.0.
This way you will see the deprecation warnings and the new suggestions.

Re: Migration 1.4 -> 7.0: org.apache.wicket.markup.html.link.PageLink

[Sébastien Gautrin]

You should most likely do incremental migration, e.g.:

 * 1.4.x -> 1.5.x
 * 1.5.x -> 6.0.x
 * 6.0.x -> 7.0.x

In between each migration, check what is now deprecated, which then will 
most likely have information about its replacements.


As for your specific issue, there's some information that seems somewhat 
relative to that in the Wicket 7 migration guide




  InlineFrame uses IPageProvider WICKET-5347
  

IPageLink has been removed because it was superseded by IPageProvider. 
Its last usage has been removed from InlineFrame



Having still yet to migrate from 1.5.x I cannot help you more though.

Re: Handling page refresh or redirect when the server reboots

[Sébastien Gautrin]

I don't have a "wicket-way" for this. However, if I had to do something like 
that, I'd try the following simple and extremely basic approach (which would need to be 
refined to be more than just an ugly hack)

1. after the action triggering the upgrade process, trigger a javascript on the 
client side
2. this javascript would poll a given url (e.g. current page or application 
home or a specific bookmarkmable page, the latter being probably better)
1. as long as the polled url does not return (within a short timeout) or 
returns an error code (depending on your setup: if the app is behind a proxy, 
you'd expect a 502/503 error as long as the app is not up)
2. once the poll returns a non-error, the javascript would trigger the 
redirect (it could also probably trigger a modal login form on the current page 
instead)

Note that I myself feel this approach would be very hacky and is most likely 
not the best way to do it with wicket, but this should at least work for your 
purpose, and maybe give you an idea on how to do it better.

not work.  At this time we just have a message telling the user to refresh
the page and when everything is ready he will be sent to the login page.

Is there a good robust way to make sure that the page is automatically

Personally I don't think this is not a good idea but this feature is a
requirement and I want to explore it as much as possible.

Re: Wizard customization

[Sébastien Gautrin]

I'll just answer quickly for now (still at work and don't want to stay 
too much longer), and complete later if noone else has detailed it more.


Basically what you need to customize the generated HTML is to extend the 
Wizard class with your own (e.g. class MyWizard extends Wizard), and 
then create a markup file for "MyWizard": this is the markup Wicket will 
then use. Of course, you'll need to have adequate wicket:id in your 
markup (so start by copying the content of the markup file for the 
Wizard that you can find in the jar).


Entropy wrote:

Question 3: Also, my page is being thrown off by the nested table structures
that the Wizard component generates.  My webby guy says he didn't anticipate
that when he wrote our templates and it really demolishes the look and feel.
Is there a way I can control the HTML the wizard generates?  To make it just
use divs or something?

I have a hunch I am going to have to give up on the Wizard entirely.  Which
makes me a sad panda.

Anyone have ideas on how to rescue this?  because Wizard seemed like such a
good fit for the process flow.

Re: i18n in reusable panels / markup traversing question

[Sébastien Gautrin]

Hello,

For your property discovery mechanism, I'm not sure I really see how 
this works (sounds interesting though). However, what you want for 
traversing the component hierarchy upon initializing your panel is to 
delay the initialization after the panel has been added.


And there is a method defined in Component exactly for this purpose: 
onInitialize() (well this is on wicket 1.5, but I don't think it has 
changed in wicket 6). Basically you would do in this method (don't 
forget to call super.onInitialize() though) whatever you would 
otherwise have done in the constructor but requires access to the 
component hierarchy.



This method is meant to be used as an alternative to initialize 
components. Usually the component's constructor is used for this task, 
but sometimes a component cannot be initialized in isolation, it may 
need to access its parent component or its markup in order to fully 
initialize. This method is invoked once per component's lifecycle when 
a path exists from this component to the Page thus providing the 
component with an atomic callback when the component's environment is 
built out.



Hope this helps.

Hi all,
I have a question concerning resuable panels, translation and the markup
traversing.

e.g. I have a page, which has its own property file providing
translation for a delete button.
This page deletes, lets say "Cars", so the buttons label should "delete
car".

On this page is a resuable panel for the delete action. Opening a
dialog... ask the user, to be sure etc. and here also, the headline
should be "delete car"

So, the panel should try to find the nearest label "delete" in the
markup hierarchy.

But: I always run into problems finding these labels, because the
component (on its init) is not part of a markup hierarchy, yet.
Cannot find key exception...

What I dont want to do is, giving all page specific texts and
translation to the reusable delete panel.
Doing so I loose this great wicket feature, just traversing the hierachy
tring to find the nearest matching translation.

What I'm doing wrong? How can I handle this in a best way?
Must be something easy, I just cannot see...

kind regards

Re: Eclipse or IntelliJ

[Sébastien Gautrin]

Personally I've been using IDEA since version 11, always on Linux, and 
from my view it's on the contrary quite faster than Eclipse, with a 
maven support that is not riddled with bugs.


Version 11 was as far as I'm concerned actually much cleaner and nicer 
than Eclipse ever was, and with version 12, the darkula theme is simply 
amazing: if I had to go back to work with Eclipse, the first I'd need 
would be to find a theme for it as close as possible as that theme.


P.S. for the cost part of IDEA that has been mentioned previously in the 
discussion, for those of you who work on Open Source projects, there's 
the Open Source Project License which gives you access to the full IDEA 
for free (same applies for Classroom License).

memory leak somewhere and its just a GC going off, I should load it in
VisualVM and see. There are other annoying things about Eclipse with

Tried IntelliJ once and it was terribly slow (and looked a bit ugly on

At the end of the day... anything's better than vim/emacs :-)

Re: Strange behavior of TextField and AjaxFormComponentUpdatingBehavior

[Sébastien Gautrin]

Well with the library linked by Cédric which let's you have "html5 
placeholder" for older browsers, you actually don't have to touch 
anything in the layout to use that. All you need to do is have your 
wicket component (TextField most likely) contribute to the header the js 
dependencies (with renderHead(Response)), as well as attach to it an 
AttributeModifier which will define the "placeholder" attribute. (and if 
you don't need support for older browsers, all you need it then the 
AttributeModifier).

For the placeholder thing you can use the standard HTML5 way with a

the client need it) :

Re: Manual procedure to update Wicket for NetBeans

[Sébastien Gautrin]

For your exact situation, I suppose the maven-gae-plugin 
(https://github.com/maven-gae-plugin/maven-gae-plugin ) will solve your 
problem.


For other situations where there's no maven plugin to do what whas done 
in an ant task, there's a maven-antrun-plugin 
(http://maven.apache.org/plugins/maven-antrun-plugin/ ) which allows you 
to run ant task within the maven build process.

Hi Ian,

May I ask you why you avoid Maven ?
With Maven (and similar dependency management tools) I just change X.Y.Z

X.Y.Z+1 in one place and continue working without bothering with all these
steps.

1.  The documentation for Google App Engine for Java (GAE/J) specifies
certain Ant scripts for doing useful things such as application building and
DataNucleus JDO datastore code "enhancement", so I do not want to drop Ant.

2.  I know almost nothing above Maven, except that this seems to be simple
to use with little configuration required to obtain the .jar (and source?)
files needed (and perhaps build an application too?).

3.  I do not know if Maven and Ant are incompatible, although I feel that
they are.

To conclude, I feel that Maven is good and the "modern, sensible way to go",
but for now I'll stick to Ant, in order to avoid the possible requirement to
change all my GAE/J Ant scripts to Maven things.

I'm happy to be told that I am wrong in all this!

I had to change my procedure for Wicket 6 to include the use of Maven.org,
in order to obtain source code files which I could no longer find in the
download mirrors. I shall be happy to update this procedure in the future to
reflect future changes or improvements if you want me to (just let me know
where it resides (if you want to use it)), even though I guess that Maven is
more the future than Ant is.

The core Wicket Bootstrap currently just provides the bootstrap
artifacts. And for the foreseeable future, I don't expect it to go
beyond that too much.

I still am on the fence on:

- whether a Bootstrap component library should be part of Wicket
- whether l0rdn1kk0n's implementation is the way to go

If you need a component library now, you should really use
l0rdn1kk0n's implementation. Currently that project has the freedom to
move at a different pace than Wicket, so that is a benefit. If/whether
that ends up at Apache is unknown.

At €-dayjob we are starting to develop Bootstrap applications and we
are experimenting with building our own component libraries. If they
end up looking like l0rdn1kk0n's bootstrap implementation, we'll
gladly move to that project, and start advocating its adoption as a
wicket core project, or start pointing folks at that particular
implementation.

For now, Wicket's bootstrap is just there to support the new examples
and might be folded into them. I think the wicket examples are a
special case that usually don't have the same requirements for
components as your typical 'enterprise' application, and wouldn't
benefit of l0rdn1kk0n's implementation.

Is this a correct summary of the current state Twitter Bootstrap support
in Wicket?

1.  The Wicket experimental does not provide any component
implementations. It merely provides a class for convenient inclusion of
the appropriate CSS + JS resources required for Twitter Bootstrap to
work via doing this in any page class that requires it:
 @Override
public void renderHead(IHeaderResponse response) {
 super.renderHead(response);

 Bootstrap.renderHead(response);
}

2.   The l0rdn1kk0n Wicket-Bootstrap project (pity about the weird
name!) has a few Wicket components specialized for Twitter Bootstrap use
and includes support for some free Bootstrap schemes.

Some questions:

How far off before Wicket bootstrap experimental gets some native wicket
components?
Could Wicket bootstrap experimental integrate the work of the
l0rdn1kk0n, bringing in some of it's components to leverage of existing
work by that project?
Will Wicket bootstrap experimental be so radically different to the
l0rdn1kk0n that porting to Wicket bootstrap experimental will be a
bothersome task when it's ready?

You can actually put the wicket namespace for child pages and

Re: Wicket and jQuery UI

Hi Pointbreak,

At least for wicket-jquery-ui, it offers also pure behaviours 
integration for jquery extensions that are pure behaviours (such as 
Droppable). I think wiQuery does as well. For ease of defining such 
things for you own component, it is the main goal of wicket-jquery-ui; 
take a look at the three tutorials Sebastien made (sebfz1) for 
wicket-jquery-ui: 
http://code.google.com/p/wicket-jquery-ui/w/list?q=label:How-To (note: 
Sebastien is the author of wicket-jquery-ui).


More on the topic, I as well would welcome experience returns from 
people who used both (though personally I'm inclined to use 
wicket-jquery-ui at the moment, but that's also because I'm biaised 
after having been really impressed at how fast Sebastien integrated run 
fox software Datepicker component to wicket-jquery-ui while doing his 
tutorial#3).

offer an Accordion component, Autocomplete component, etc.). Imho, a
much more flexible approach for JQuery integration is to offer all
jquery-ui functionality as behaviors. That way existing components (both
from core, other libraries, or your own code) can more easily be
augmented with jqeury-ui functionality. And since it's easy enough to do
it yourself with a few lines of code, I opted to don't use these
libraries at all.
There are a few things that require more thought (e.g. jQuery Tab-UI
combined integrated with Wicket-Ajax functionality, but at least back
then these frameworks didn't offer that in a flexible way either).

So I would say, check the libraries for how you are supposed to add the
jquery functionality (behavior vs component hierarchy), and don't be
afraid to just roll your own if necessary. It's not that much extra
functionality that the library offers over just using raw Wicket and
jQuery.

My 2cnts.

Hi

I was not thinking about  the base, ie AbstractDefaultAjaxBehavior.

I was thinking about using one off the API - several components - could
be accordion? could be some effects etc.

So I was thinking about who has tried out both API's - has some
experiences and suggest this API because bla bla.

Hope I explain myself fully here.

What exactly do you need ?

The "bridge" is AbstractDefaultAjaxBehavior - the base Ajax behavior.


Recommendations and experience would be very much welcomed.

Re: Datepicker with range selection support

[Sébastien Gautrin]

I'll do that. I had looked at the content of the 1.2.3-SNAPSHOT on 
sonatype and didn't see anything either. However, if there was not a 
clean between deploying the 6.0.1 and the 1.2.3, that might very well be 
the cause. I noticed several times in the past few quirks with maven 
like that where it wouldn't recompile some files after switching 
versions/branches while they had changed on disk.


I'll keep you informed after testing tonight.

Hi Sebastien,

Well, I am a little bit confused because it is technically almost
impossible to deploy a wrong version.
I checked the 1.2.3-SNAPSHOT source on the Nexus repository and it seems to
be correct.

What I know is that I deployed the 1.2.3-SNAPSHOT just after the
6.0.1-SNAPSHOT. I remember I did not recompile explicitly (but deploy phase
comes after compile and install) and the branch switching may have caused a
kind of mistake. To be sure, I will clean/install/deploy a new snapshot
tonight. If you can retry tomorrow morning and let me know, it would be
nice!

Thanks & best regards,
Sebastien.

The situation is the same with the samples (and for the samples, that
can't be a dependency configuration mistake of mine).

So I'd really think there's something wrong with the 1.2.3-SNAPSHOT on
sonatype (the one from September 22).

Note : just noticed that in the earlier mail I had forgotten to tell I was
requesting 1.2.3-SNAPSHOT for a wicket 1.5.8 app, and installing from
master, so I wasn't very clear in the end, sorry.

  Agreed with Martin; that's also explain why it is working when you build

it
manually (the default branch - master - is the wicket 1.5.x version).
Please note that the snapshot repository hosts both 1.2.3-SNAPSHOT (for
wicket 1.5.x) and 6.0.1-SNAPSHOT (for wicket 6.0.0).

Sorry if it was not clear enough,

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/

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/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)

Sebastien.

Re: disabling ajax submit button

[Sébastien Gautrin]

Which wicket version ? (I ask because I see you are using several calls 
that are deprecated in 1.5).
Besides, within the declaration of your inner class, don't try to access 
the variable you are defining

(and without declaring it final, it should normally not compile anyway).

Not changing the deprecated calls, this should probably look like :

add(new SimpleAttributeModifier("disabled", "disabled"));
target.addComponent(this);

Re: wicket-select2 as AutoCompleteTextField replacement

[Sébastien Gautrin]

Hi,

If you only need a static list of initial choices (non ajax), you 
should be able to simply use select2's tagging support with something 
like (didn't test it):

// model is your IModel for the selected data
Select2Choice choice = new Select2Choice("choice", 
model);

choice.getSettings().setTags("A", "B", "C");

You can of course also use a Select2MultiChoice for multiple choices.

Now if you need Ajax support, it's somewhat more complex, though for 
the simple case where you don't need to mix static choices and ajax, 
you could use a standard Select2Choice (or MultiChoice), and in the 
query method of your choice provider prepend the query string to the 
list of results.

Re: [1.5] [6.0] dynamically named CSS, JS & images resources

[Sébastien Gautrin]

Hi,

In your case, the general idea would be to create a ResourceReference to 
your downloaded css & js files, and then on your base page to contribute 
them dynamically with


@Override
public void renderHead(IHeaderResponse response) {
ResourceReference jsRef = [...]
ResourceReference cssRef = [...]
response.renderJavaScriptReference(jsRef);
response.renderCSSReference(cssRef);
}

Now for creating the ResourceReference for your files, there's several 
options depending on what you want to do:
- if you want to refer directly to the external css/js, just do 
response.renderJavaScriptReference("http://example.com/jsfile.js";); I 
wouldn't do that unless the other site is a site you control and want to 
use as a CDN
- you could load the data from the db: 
http://wicketinaction.com/2011/07/wicket-1-5-mounting-resources/ gives 
an example for images, wouldn't be much different with a file
- you could save the downloaded files in a specific directory, mount 
that directory as a sharedresourcereference, and serve the files that 
way: see http://stackoverflow.com/a/9232848 for more information


There's probably other ways (better maybe) though.

I use Wicket 1.5.7 but a solution for Wicket 6.0 is OK as well.

Re: How to Logout

[Sébastien Gautrin]

Hi,

The LogoutPage in the application I work on is quite simple:
- first we invalidate the session with session.invalidateNow() like you do
- second we throw a RestartResponseAtInterceptPageException with the 
Page we want the user to go to after the logout process (actually we use 
it with the class of the Page we want, but you can pass it an instance 
of a Page).


Hope this will help.

Hi

I'm trying to implement a simple logout mechanism with the need of
complete session termination.

For this I created a LogoutPage and mounted it using
mountPage("/logout", LogoutPage.class);

Now this page contains multiple components and a link to change
langugage etc, therefore it is stateful.
But when I perform a session.invalidate(Now)() in the page's
constructor, the user gets redirected to /logout?0 with a new session
ID. Probably though the page was stored in the previous session so it
doesn't exist with the new one, then he gets redirected back to /logout,
back to /logout?0 and so on.

What do I have to do to implement this simple logout page?

Thanks

Matt
