date:20070503

I'm using a custom ListView to generate a table.  The content of the
table consists of four columns of data.  I have that working just
fine.  But I'd like to add an additional table row on occation to
group rows of data in the table.  Thus, there would be a groupRow
that specifies a date, then many availRows of data for that date, then
another groupRow, more availRows, and so forth.

Here is some example HTML.  I know that this HTML and code will not
work the way it is now -- it is just meant to illustrate.  The first
TR should only be displayed when the date changes.  Otherwise, only
the second TR should display in each populateItem.

table
tr wicket:id=groupRow
td colspan=4 wicket:id=date/td
/tr   
tr wicket:id=availRow
td wicket:id=lastName/td
td wicket:id=firstName/td
td wicket:id=startTime/td
td wicket:id=endTime/td
/tr
/table

Here is the custom ListView's populateItem:


protected void populateItem(final ListItem item) {
SimpleDateFormat dateDateFormat = new SimpleDateFormat(M/d/);
SimpleDateFormat timeDateFormat = new SimpleDateFormat(h:mma);
ReportRow rr = (ReportRow) item.getModelObject();
Date update = getStartDate(rr.getStartTime());
if (current == null || current.getTime()  update.getTime()) {
current = update;
item.add(new
Label(date,dateDateFormat.format(rr.getStartTime(;
}
else {
item.add(new Label(lastName,rr.getLastName()));
item.add(new Label(firstName,rr.getFirstName()));
item.add(new
Label(startTime,timeDateFormat.format(rr.getStartTime(;
item.add(new
Label(endTime,timeDateFormat.format(rr.getEndTime(;
}
}

Re: [Wicket-user] Sessionless Wicket?

In 1.3 you can use stateless pages (with stateless links and stateless
forms). However, you'll have to sacrifice the programming model in
favor of statelessness a little. I'm not really sure it's worth it.

 I know that I read somewhere that there is, or is going to be, a way to run
 your wicket application without creating a session (until absolutely
 necessary).  We have a site that has mostly been converted to Wicket now,
 and almost all of it is state-less data  The URLs are all bookmarkable
 (98% of them are), so there is not much state to track.  We don't need a
 full object graph of all your pages and components, except for on very few
 pages once you have signed in.

 We're experiencing out of memory problems increasingly with an increase in
 traffic.  I'm not holding much in the session, but objects are held in pages
 and components I now believe we should have used detachable models for
 many things rather than directly holding a reference to a DB-backed object.
 Should I start by going back and retrofitting many of those private
 references within components to use detachable models so that the objects
 are not held in memory?

 Any other suggestions?

 Thank you!

Re: [Wicket-user] Ajax Request problem with new window tabs (Wicket 1.3 snapshot)

2007-05-03 Thread RedFury



Ok I have spent a fair amount of time putting together a wicket example of
my two problems.  It is a netbeans project but pretty bare-bones so it
should be pretty easy to get working in other IDE's.  I have attached it
here so if any of the wicket-gurus out there would take a quick look I would
very much appreciate it.

Basically there were two problems and this is how I reproduced them:

Problem 1 - Ajax failing to update (requesting wrong page version maybe..?)

Happens on all browsers (IE, Firefox, opera tested.)
Open up firefox and paste app URL
Click on Tab 3 (ajax request will put tab 3 up)
Click back on Tab 1
Open up second tab and paste URL
Go back to first tab and look at Wicket Ajax debug.  Update is failling
because the server is sending Component ID's which don't exist on the
client.  They've got their pages mixed up.



Problem 2 - Back button - Forward button failure

Happens only on Firefox (I think) so maybe a browser problem ?
Open up firefox and go to any site, I usually used google
Paste app URL into browser.
Click on Tab 3
Click the back button to go back to google.
Wait a while for page to 'expire'. Doesn't seem to take more than about 30
secs - 1min.
Click forward.   Server is contacted and page reset, showing tab 1.
Click on a subtab of tab1.  You'll get an error saying the page couldn't
find the component/behavior, as if it still
thinks it is on Tab 3 (?)

Anyways, thats about all I can add for now.  If someone would be so kind as
to have a quick look at the attached project and offer some feedback, that
would be awesome.

Cheers,
Dean

 Sorry for replying to my own post, but I found another problem which seems
 to be related or the same thing.
 I'm not sure if its wicket 1.3 or my code but I'm going to try to write a
 simple app to demonstrate the problem then submit it here.
 
 Anyways, if I open my browser (firefox latest, fully updated) and start on
 a different, non-wicket page (say google)  Then go to my wicket app.   I
 have a bunch of ajaxed tabs which start out on tab 1 when the page loads.
 Each tab loads in a bunch of new html components in a panel, replacing the
 old panel.  So I click on tab 2 and new html gets ajaxed in, replacing a
 lot of the old components in tab 1.   Then I click 'back' to go back to
 the non-wicket page.  I sit on that page until the wicket-page has timed
 out, then click forward now.  Now the server loads my page again, and its
 reset back to its original form with tab 1 showing.  However, if I try to
 perform an ajax action within that tab, I get a server error telling me
 that it couldn't find the panel, because the server has got some weird
 state where even though it fetched me the reset page, it still thinks I'm
 on the modified page when I submit an ajax request.
 
 All this is very weird and probably doesn't make much sense without a
 solid example, so I'm going to try to put one together and hopefully some
 wicket guru can find out if its a bug or something I'm doing in my code
 which I shouldn't be.

 Hi Matej,
 
 I got the latest SVN trunk and it did indeed fix the 'session expired'
 problem.  However, another problem with opening a new tab still persists
 and I think it may have to do with page cloning combined with dynamic
 ajax page updates.  I will try to explain as best I can but I'm not
 overly familiar with the internal workings of wicket.
 
 My app has 1 main page, and everything else is loaded dynamically using
 Ajax.  I perform the following steps after deploying my app:
 
 -Open firefox and paste the link to my wicket servlet.  A new page, Page
 A, is created on the server using PageMap A.  By default, my Page A is
 constructed with 5 tab options, with the contents for Tab 1 loaded.
 
 -I click on tab 2 in Page A.  This sends of an AJAX request which
 dynamically replaces panels on Page A (specifically replaces
 tab-content-panel-1 with tab-content_panel-2.)
 
 - I open a new tab and paste the servlet link into it.  The following
 occurs:
 
 - Two new pages appear to be created (at least my Page A constructor is
 called twice), lets call them Page B and Page C.  Page B uses Pagemap A
 again, and by default is created with Tab 1 loaded again.  Page C uses a
 new pagemap (PageMap B) and all subsequent ajax requests from the second
 tab appear to go to Page C, as you would expect.
 
 - Back in Tab A, the next ajax request is activated and this is when
 things go bad ... I get errors because its trying to update components
 that don't exist on the page.  Upon inspection, what is happening is that
 the AJAX request from Tab 1 seems to be targetting a different page, with
 different page state, quite possibly page B.   It's AJAX error spits out
 the ID's of things it can't find and they are all ID's that belong to
 components inside Tab-Panel-1.  So the AJAX request to the server grabs

Hi all, just want to say that I've relatively new to Wicket but am loving
every minute of it! In just a few weeks of learning and programming I have
been able to create a robust, javascripted, ajaxified app for our company.
Great work to the devs!

However, I have one problem which I'm a little unsure how to solve, its not
an inherent problem with Wicket but more a problem with my ajax in wicket.
I will try to go into as much detail as possible.

I have a page with a set of tabs. Each tab will replace the main body of
the page with different components using ajax. this is all working great.
On top of this, the main page of the app has a global timer (using
AbstractAjaxTimerBehavior) which does any updates required for the current
tab. So lets say I have component C1 on tab T1 (T1 is a wicket panel which
I replace when needed.) The ajax update will call an update() function
which is overloaded for the different tab types. So T1.update() will call
target.addComponent(C1); etc..

The problem I am having is in the timing between the ajax timer request and
the ajax update request when the user hits a new tab. I am getting the
following error:

java.lang.NullPointerException
at
wicket.request.compound.DefaultRequestTargetResolverStrategy.resolveListenerIn
terfaceTarget(DefaultRequestTargetResolverStrategy.java:295)

at wicket.RequestCycle.step(RequestCycle.java:992)
at wicket.RequestCycle.steps(RequestCycle.java:1084)
at wicket.RequestCycle.request(RequestCycle.java:454)

So it seems what is happening (this is my guess) is that the ajax requests
for the timer update and the new tab update are being sent almost
simultaneously. The first request is processed by the server and this
actually changes the comoponents on the page. Then the second request comes
in and its target behavior no longer exists because the first request
replaced that component (panel) with something different.

So I guess what I'm looking for is ideas on how to solve this problem? How
does Wicket ajax work client side? Does it organize ajax request-response
cycles one at a time, or can they be sent simultaneously? Also, is there a
way I can hoook into the client code and stop the timer update from being
called if we've already got a pending page-change ajax request.

So I've waffled a bit, in short how do I stop the second ajax request from
referencing behavior that the first one just got rid of ?

Thanks,
Red Fury

   add methods like String getClass(), String getStyle() to the

   and length0
  
   3) expand AbstractChoice
   add the mentioned methods (params like the method isDisabled()) to

 its parent before updating it again, to prefent it from going on forever. We
 couldn't find a way for this. Component has a remove() method, but
 IBehaviour does not. What is the preferred way to do this?

 Thanks in advance,

 the quoted 'm' should be replaced with a w. the right line is:

 after that change, everything works great.

Re: [Wicket-user] Sessionless Wicket?

Stateless pages are available even in 1.2, but much more limited.
Basically, when you have no callbacks, you're page will be stateless
and not kept in memory. You'd have to do everything with bookmarkable
pages, links and page parameters then.

In 1.3, you can use some callbacks while still keeping pages
stateless, e.g. using StatelessLink and StatelessForm. There's a
simple example showing this in wicket-examples:
org.apache.wicket.examples.stateless

In your case, if really most of your app is read-only, it's probably
worth using that. And finally, a big improvement in 1.3 over 1.2 is
that as long as users don't have a HttpSession assigned by the server,
and they are only accessing stateless pages, no session will be
created by Wicket either, giving you more options in clustering and
further decreasing the memory footprint.

It is possible to even further optimize bits by digging deeper in
Wicket, but for now, this should help quite a lot.

Re: [Wicket-user] Reusable Panels/Nested Forms/Models and weird behaviour

Thanks Igor and I am curious. Why is it nasty in your opinion? Which parts? I
am open to trying other ways that I am not aware of. This is not how I
originally wanted to implement it but I have tried many ways so far
(different models on different components in the hierarchy,
nesting/inheriting models etc) and this is the closest to working so far.
Other ways I tried which seemed more elegant had more serious problems in
practice especially when compounding and nesting panels more times which I
need.

[Wicket-user] RadioGroup.. Correct usage (with enum values)?


I have problems with radio groups. According to docs and tutorials the
group's model object should be set to the selected radio model object.
However, in my case (using enum values which must be set on an enum
property) the group's model object always seems to be null. I based my code
on the tutorial at http://cwiki.apache.org/WICKET/using-radiogroups.html

My code below produces..

test was pressed:null, null, Tenant, CompanyTenant

//
RadioGroup group = new RadioGroup(reportType, new
PropertyModel(getReportTenantDTO(), reportType));
Radio radIndividual = new Radio(individual, new Model(ReportType.Tenant));
Radio radCompany = new Radio(company, new
Model(ReportType.CompanyTenant));
group.add(radIndividual);
Button test = new Button(test){
protected void onSubmit(){
info(test was pressed: + 
getReportTenantDTO().getReportType() + , 
+
 group.getModelObject() + ,  + 
radIndividual.getModelObject() + , 
+ radCompany.getModelObject());
}
};

Re: [Wicket-user] Reusable Panels/Nested Forms/Models and weird behaviour

One thing that I'm wondering is why you declare your components as
member variables. It's not really wrong, but it's more code without
any advantage, and potentially scope creep (in that you might be
tempted to use the components directly rather then to work through
models.

Re: [Wicket-user] Reusable Panels/Nested Forms/Models and weird behaviour

The drop down list does not directly relate to the form model (as the visible
value is a user readable summary not the data structure I need) and so I
need to keep a reference to something even if its a model or two. Take a
look at this version which still works with same quirks.. Any better?

Re: [Wicket-user] Ajax Request problem with new window tabs (Wicket 1.3 snapshot)

Hi

About the first problem, it should be fixed since yesterday. Could you
please update your
wicket to see if it really is?

I can't reproduce the second one. I tested it with Firefox 2.0 on OSX
and everything works as expected. I remember seeing something like
this in 1.5. What FF version do you use?

-Matej

On 5/3/07, RedFury [EMAIL PROTECTED] wrote:


 Ok I have spent a fair amount of time putting together a wicket example of
 my two problems.  It is a netbeans project but pretty bare-bones so it
 should be pretty easy to get working in other IDE's.  I have attached it
 here so if any of the wicket-gurus out there would take a quick look I would
 very much appreciate it.

 Basically there were two problems and this is how I reproduced them:

 Problem 1 - Ajax failing to update (requesting wrong page version maybe..?)

 Happens on all browsers (IE, Firefox, opera tested.)
 Open up firefox and paste app URL
 Click on Tab 3 (ajax request will put tab 3 up)
 Click back on Tab 1
 Open up second tab and paste URL
 Go back to first tab and look at Wicket Ajax debug.  Update is failling
 because the server is sending Component ID's which don't exist on the
 client.  They've got their pages mixed up.

 

 Problem 2 - Back button - Forward button failure

 Happens only on Firefox (I think) so maybe a browser problem ?
 Open up firefox and go to any site, I usually used google
 Paste app URL into browser.
 Click on Tab 3
 Click the back button to go back to google.
 Wait a while for page to 'expire'. Doesn't seem to take more than about 30
 secs - 1min.
 Click forward.   Server is contacted and page reset, showing tab 1.
 Click on a subtab of tab1.  You'll get an error saying the page couldn't
 find the component/behavior, as if it still
 thinks it is on Tab 3 (?)

 Anyways, thats about all I can add for now.  If someone would be so kind as
 to have a quick look at the attached project and offer some feedback, that
 would be awesome.

 Cheers,
 Dean

  Sorry for replying to my own post, but I found another problem which seems
  to be related or the same thing.
  I'm not sure if its wicket 1.3 or my code but I'm going to try to write a
  simple app to demonstrate the problem then submit it here.
 
  Anyways, if I open my browser (firefox latest, fully updated) and start on
  a different, non-wicket page (say google)  Then go to my wicket app.   I
  have a bunch of ajaxed tabs which start out on tab 1 when the page loads.
  Each tab loads in a bunch of new html components in a panel, replacing the
  old panel.  So I click on tab 2 and new html gets ajaxed in, replacing a
  lot of the old components in tab 1.   Then I click 'back' to go back to
  the non-wicket page.  I sit on that page until the wicket-page has timed
  out, then click forward now.  Now the server loads my page again, and its
  reset back to its original form with tab 1 showing.  However, if I try to
  perform an ajax action within that tab, I get a server error telling me
  that it couldn't find the panel, because the server has got some weird
  state where even though it fetched me the reset page, it still thinks I'm
  on the modified page when I submit an ajax request.
 
  All this is very weird and probably doesn't make much sense without a
  solid example, so I'm going to try to put one together and hopefully some
  wicket guru can find out if its a bug or something I'm doing in my code
  which I shouldn't be.
 
  Cheers,
  Dean

  Hi Matej,
 
  I got the latest SVN trunk and it did indeed fix the 'session expired'
  problem.  However, another problem with opening a new tab still persists
  and I think it may have to do with page cloning combined with dynamic
  ajax page updates.  I will try to explain as best I can but I'm not
  overly familiar with the internal workings of wicket.
 
  My app has 1 main page, and everything else is loaded dynamically using
  Ajax.  I perform the following steps after deploying my app:
 
  -Open firefox and paste the link to my wicket servlet.  A new page, Page
  A, is created on the server using PageMap A.  By default, my Page A is
  constructed with 5 tab options, with the contents for Tab 1 loaded.
 
  -I click on tab 2 in Page A.  This sends of an AJAX request which
  dynamically replaces panels on Page A (specifically replaces
  tab-content-panel-1 with tab-content_panel-2.)
 
  - I open a new tab and paste the servlet link into it.  The following
  occurs:

[Wicket-user] Applet not loaded in 1.2.6, but in 1.2.5, and viceversa, depending on codebase [jetty-server]

2007-05-03 Thread manu

Dear people,

I have found the following strange behavior in wicket-1.2.6:

Since long time ago I've been using wicket-1.2.5, and testing a
webPage where there's an applet with the following codebase:

param name=codebase value=lib /

Yesterday, I decided to update to wicket-1.2.6, and then, while
testing this webPage again, I found ClassNotFoundException during
applet's loading.

So, after a little time doing try-and-error, I noticed that changing
the codebase to the following, then it worked fine:

param name=codebase value=../lib /

I am using the lightweight jetty-server with the configuration
inherited from wicket-examples. Nothing has changed during this
development time, then, only the classpath in my Eclipse project, were
I just changed to wicket-1.2.6.

Any idea why is this happening?

Thank you ;)

Re: [Wicket-user] Reusable Panels/Nested Forms/Models and weird behaviour

Yeah, looks better to me. As a matter of good practice (imho), you
could probably make the form a static internal class and make the
members private instead of package private. Though that's just taste I
guess. :)

Other ways I tried which seemed more elegant had more serious problems in

[Wicket-user] AbstractRequestTargetUrlCodingStrategy is throwing an error now...

2007-05-03 Thread ChuckDeal


Wicket 1.3 (revision 534800, updated 08:00am EST 5/3/07)

I finsihed updating my code to the trunk yesterday and my pages were loading
correctly.  I did an SVN update this morning just to pick up the latest
changes and now AbstractRequestTargetUrlCodingStrategy  is throwing an
exception URL fragment has unmatched key/value pair: mode/:/0

The action: click an AjaxLink that does something similar to the following:

StringBuffer sb = new StringBuffer(128);
sb.append(window.location.href=');
sb.append(/app/specChange/specChangePage/mode/add);
sb.append(';);
target.appendJavascript(sb.toString());

Upon debugging the problem,
AbstractRequestTargetUrlCodingStrategy.decodeParameters actually gets called
twice; first with /mode/add (as expected), but then (i can't tell exactly
when, but around the time the page is actually rendering) it gets called
with mode/:/0 (not expected, and incorrect which is causing the
exception).

There were only a handful of files changed in SVN between me updating on the
morning or 02MAY07 and 03MAY07.  So, can anyone help me find where the URL
might be getting changed?

Chuck

[Wicket-user] Header contributions and AjaxLink

2007-05-03 Thread John Krasnay

I think I may have found a bug with header contributions, AjaxLink, and
Internet Explorer. Here's a test page:

html
  body
div wicket:id=subComponent/div
  /body
/html

---8---

public class TestPage extends WebPage {
public TestPage() {
add(new SubComponent(subComponent));
}
}



SubComponent is defined as follows:

html
  head
wicket:head
  wicket:link
link rel=stylesheet type=text/css href=SubComponent.css
  /wicket:link
/wicket:head
  /head
  body
  
wicket:panel
a wicket:id=link href=#Click Me/a
span wicket:id=label/span
/wicket:panel

  /body
/html

---8---

public class SubComponent extends Panel {

private int count = 0;

public SubComponent(String id) {
super(id);

add(new AjaxLink(link) {
@Override
public void onClick(AjaxRequestTarget target) {
count++;
target.addComponent(SubComponent.this);
}
});

add(new Label(label, new PropertyModel(this, count)));

setOutputMarkupId(true);
}

public int getCount() {
return count;
}

}




Under Firefox this works fine: clicking the Click Me link causes the
count to increment on the page. But under IE, the number does not get
updated on the page (even though the count is being incremented on the
server). The debug window gives the following error:

INFO:

The problem appears to be the wicket:head portion of the SubComponent.
Comment this out and it works correctly on both IE and Firefox. Note
that SubComponent.css is empty. I've tried this on Wicket 1.2.4 and 1.2.6.

Any thoughts?

[Wicket-user] Test Case - Nested Forms/Models and weird behaviour

OK. Below is a test case quick start application eclipse project that
produces the quirks I have been describing.

ftp://ftpuser:[EMAIL PROTECTED]/wicket-quickstart-1.2.6.rar

The test procedure to reproduce strange behaviour is as follows.

1. Enter postcode in first address.
2. Hit address search (you will then see your postcode appearing in other
fields unexpectedly)
3. Select first option from first drop down and hit use address (This will
appear to work apart from the extraneous postcodes)
4. Select second option from first drop down and hit use address (then all
addresses will be filled unexpectedly)

I suspect this behaviour relates to nested forms as without the outer form
it appears to work as expected. I am also beginning to suspect that this may
be the root of my other problem with radio groups behaving oddly.

Hope this helps and thanks,
John

The form that adds these panels does it as below

add(new AddressPanel(proposedAddress,

add(new AddressPanel(currentAddress,
getCreditCheckDTO().getCurrentAddress()));
add(new AddressPanel(previousAddress,
getCreditCheckDTO().getPreviousAddress()));

The form has a compound property model has a pojo for its model object.
This is returned by getCreditCheckDTO().

Re: [Wicket-user] Sessionless Wicket?

2007-05-03 Thread Jeremy Thomerson


Thanks to everyone for their help - I'm starting right away to convert
everything to detachable models for all domain objects that are loaded into
components...

Eelco, I am curious about your statement when you have no callbacks, you're
page will be stateless and not kept in memory...  Most of my pages have no
callbacks (by callback, I'm assuming that you mean a link that would have
reference to wicket components in the URL, meaning that it is storing the
state of that component so that it can further interact with it).  I have
taken great care to control the URLs of the application, so almost every
page has only components that have standard URLs, with no references to any
components, etc.  The forms will obviously have a call back, and certain
links (particularly if you are signed in as an administrator - a lot of
links appear to edit and delete content that are all direct callbacks with
obviously no direct URL encoding / decoding so that you can not use them
outside of your session).

So, how do I know if it's storing the pages in memory?  Is there something I
can do to tell it not to?

Thanks!

In 1.3, you can use some callbacks while still keeping pages
stateless, e.g. using StatelessLink and StatelessForm. There's a
simple example showing this in wicket-examples:
org.apache.wicket.examples.stateless

In your case, if really most of your app is read-only, it's probably
worth using that. And finally, a big improvement in 1.3 over 1.2 is
that as long as users don't have a HttpSession assigned by the server,
and they are only accessing stateless pages, no session will be
created by Wicket either, giving you more options in clustering and
further decreasing the memory footprint.

It is possible to even further optimize bits by digging deeper in
Wicket, but for now, this should help quite a lot.

[Wicket-user] Good Tutorial on core wicket


Hello everyone, I am about to buy this book called pro
wickethttp://www.amazon.com/Pro-Wicket-Experts-Voice-Java/dp/1590597222/ref=pd_bbs_sr_1/103-4798570-8657439?ie=UTF8s=booksqid=1178205890sr=8-1
.

But until it gets here (Argentina) would anyone point me in the right
direction to read something on-line.

What I am looking for is a tutorial / reference / on-line book / etc.
covering the CORE, architecture, vision, a guide on how to structure your
design.

I have very successfully built a good enough demo, so I got around the
reference samples, some docs, and this mailing list. But I cannot say at all
that I know wicket.

I would very much like to learn more about its internals 'cause I think that
will also guide me to better designs by knowing more of wicket potentials.


Thanks in  advance,

f(t)

PS: Does the name wicket comes from being a real wicked as in cool or
awsome framework or from the name of the cutest EWOK on Episode 6? XD.

Re: [Wicket-user] Sessionless Wicket?

 Thanks to everyone for their help - I'm starting right away to convert
 everything to detachable models for all domain objects that are loaded into
 components...

If you're only working with stateless pages, you don't detachable
models as those pages won't be stored to start with. But if you want
to reuse the models and components in stateful pages, it is better to
have that.

 Eelco, I am curious about your statement when you have no callbacks, you're
 page will be stateless and not kept in memory...  Most of my pages have no
 callbacks (by callback, I'm assuming that you mean a link that would have
 reference to wicket components in the URL, meaning that it is storing the
 state of that component so that it can further interact with it).

Yep. Normal Links, Forms, ajax requests etc.

 I have
 taken great care to control the URLs of the application, so almost every
 page has only components that have standard URLs, with no references to any
 components, etc.  The forms will obviously have a call back, and certain
 links (particularly if you are signed in as an administrator - a lot of
 links appear to edit and delete content that are all direct callbacks with
 obviously no direct URL encoding / decoding so that you can not use them
 outside of your session).

Not sure what you're getting at...

 So, how do I know if it's storing the pages in memory?  Is there something I
 can do to tell it not to?

Yeah, you can give provide a HINT that they shouldn't be stored (that
they are stateless) by overriding getStatelessHint on the components
you put on the page. Note that if there is just one stateful component
on the page, that'll trigger the page to be marked as stateful UNLESS
you explicitly mark the page itself stateless (which is a bit cheaper
by the way, as it won't iterate over it's children to find out whether
it is stateless).

The method where this all happens is Page#isPageStateless.

Also, if you want to keep track of when user sessions are created,
create a custom session store by overriding newSessionStore on
Application and let your custom store extend HttpSessionStore or
SecondLevelCacheSessionStore and then override onBind which will be
called when (new) sessions are bound to the HttpSession.

There already is an example though. Take a look at
org.apache.wicket.examples.stateless.

If you have suggestions (patches) to extend that example even more,
that'd be great, but there's really not that much to say about it I
think.

 Should I start by going back and retrofitting many of those private

 Any other suggestions?

Re: [Wicket-user] Wicket-stuff GMAP

2007-05-03 Thread Iulian Costan


where did you checked out gmap  sources from? trunk?
i dont know if any wicket 1.3 artifacts are deployed somewhere, but you can
checkout wicket source code as well and build it for yourself as a quick
workaround.

or you can get gmap code from 1.2 branch, that depends on 1.2.* wicket that
is available on central repository for sure.

Re: [Wicket-user] Adding extra row to table in ListView


what you need is a lsitview in a listview

the first outputs the date row, and then a listview that outputs rows for
that date.

makes sense?

I'm using a custom ListView to generate a table.  The content of the
table consists of four columns of data.  I have that working just
fine.  But I'd like to add an additional table row on occation to

that specifies a date, then many availRows of data for that date, then
another groupRow, more availRows, and so forth.

Here is some example HTML.  I know that this HTML and code will not
work the way it is now -- it is just meant to illustrate.  The first
TR should only be displayed when the date changes.  Otherwise, only
the second TR should display in each populateItem.

table
tr wicket:id=groupRow
td colspan=4 wicket:id=date/td
/tr
tr wicket:id=availRow
td wicket:id=lastName/td
td wicket:id=firstName/td
td wicket:id=startTime/td
td wicket:id=endTime/td
/tr
/table

Here is the custom ListView's populateItem:


protected void populateItem(final ListItem item) {
SimpleDateFormat dateDateFormat = new
SimpleDateFormat(M/d/);
SimpleDateFormat timeDateFormat = new
SimpleDateFormat(h:mma);
ReportRow rr = (ReportRow) item.getModelObject();
Date update = getStartDate(rr.getStartTime());
if (current == null || current.getTime()  update.getTime()) {

Dear people,

I have found the following strange behavior in wicket-1.2.6:

Since long time ago I've been using wicket-1.2.5, and testing a
webPage where there's an applet with the following codebase:

param name=codebase value=lib /

Yesterday, I decided to update to wicket-1.2.6, and then, while
testing this webPage again, I found ClassNotFoundException during
applet's loading.

So, after a little time doing try-and-error, I noticed that changing
the codebase to the following, then it worked fine:

param name=codebase value=../lib /

I am using the lightweight jetty-server with the configuration
inherited from wicket-examples. Nothing has changed during this
development time, then, only the classpath in my Eclipse project, were
I just changed to wicket-1.2.6.

Any idea why is this happening?

Thank you ;)

Re: [Wicket-user] Reusable Panels/Nested Forms/Models and weird behaviour


that looks much much better.

you can still get rid of those two models for the dropdownlist with:
   private AddressEntry quickAddress;
   Private ListAddressEntry quickAddresses=new
ArrayListAddressEntry();

and then

add(new DropDownChoice(id, new PropertyModel(this, quickAddress), new
PropertyModel(this, quickAddresses),...)

that way you never actually have to reference model objects directly, your
code that deals with these addresses then simply works with those two
fields. it keeps wicket out of the way.

eg

private void performLookup(boolean showAllPremises) {
...ListAddressEntry entries = AddressUtil.getAddresses(
   getAddress().getPostcode(), showAllPremises);
   addressListModel.setObject(null, entries);

becomes
quickAddresses=AddressUtil.getAddresses(getAddress().getPostcode(),
showAllPremises);

much simpler/cleaner imho

SubComponent is defined as follows:

Under Firefox this works fine: clicking the Click Me link causes the
count to increment on the page. But under IE, the number does not get
updated on the page (even though the count is being incremented on the

The problem appears to be the wicket:head portion of the SubComponent.
Comment this out and it works correctly on both IE and Firefox. Note
that SubComponent.css is empty. I've tried this on Wicket 1.2.4 and 1.2.6.

Any thoughts?

Re: [Wicket-user] RadioGroup.. Correct usage (with enum values)?


Igor,

I really suspect it is also related to my other problem post (see
AddressPanel test case) with nested forms and models working incorrectly
inside, as when I put the same radio button code outside of our app (which
needs nested forms and this is a bit of a show stopper for us) the radio
buttons then function correctly. I willl add radio buttons to my previous
test to confirm if its related when I get a chance. I am also downloading
and building 1.3 to see if something there has fixed it since 1.2.6..

Thanks,
John

What I am looking for is a tutorial / reference / on-line book / etc.
covering the CORE, architecture, vision, a guide on how to structure your

I have very successfully built a good enough demo, so I got around the

I would very much like to learn more about its internals 'cause I think

  public int getCount() {
  return count;

  Under Firefox this works fine: clicking the Click Me link causes the
  count to increment on the page. But under IE, the number does not get
  updated on the page (even though the count is being incremented on the
  server). The debug window gives the following error:

  The problem appears to be the wicket:head portion of the SubComponent.
  Comment this out and it works correctly on both IE and Firefox. Note
  that SubComponent.css is empty. I've tried this on Wicket 1.2.4 and 1.2.6.
 
  Any thoughts?

Re: [Wicket-user] RadioGroup.. Correct usage (with enum values)?


there is no nested form support in 1.2, only 1.3. so that might be it?

Igor,

I really suspect it is also related to my other problem post (see
AddressPanel test case) with nested forms and models working incorrectly
inside, as when I put the same radio button code outside of our app (which
needs nested forms and this is a bit of a show stopper for us) the radio
buttons then function correctly. I willl add radio buttons to my previous
test to confirm if its related when I get a chance. I am also downloading
and building 1.3 to see if something there has fixed it since 1.2.6..

Thanks,

[Wicket-user] TinyMCE for wicket 1.3 not a panel???

2007-05-03 Thread Apaar Trivedi

Hey all, I am trying to get a TinyMCEPanel jar for Wicket 1.3.  I've
gotten the tinymce contrib. from the wicketstuff trunk, and attempted to
compile and package it using the maven script.  It compiles just fine
but when I go to build the packages, I get this error in a few place:

 

c:\Eclipse_WS\wicketstuff\wicket-stuff_trunk\wicket-contrib-tinymce\src\
test\wicket\contrib\tinymce\TinyMCEPanelTest.java:[63,39] incompatible
types

found   : wicket.contrib.tinymce.TinyMCEPanel

required: org.apache.wicket.markup.html.panel.Panel

 

and basically this is occurring everywhere the TinyMCEPanel object is
being returned.  This mcepanel is definitely a sub class of a wicket
panel, and I am confident the maven script is using wicket 1.3 incubator
snapshot.  When I remove the test classes I can build the package just
fine.  But when I attempt to use this mce jar in my wicket application,
I cannot add this TinyMCEPanel object to the markup container because it
thinks it is not a component.  Basically the same problem the test is
having.  

 

Does anyone know what is going on with this, or is there a pre-built jar
against wicket 1.3 out there which works?

 

Any help is appreciated.  Thanks.

Re: [Wicket-user] Good Tutorial on core wicket

H igor, thanks, but could you be more specific. I do think I browsed the
wiki but couldn't find what I was looking for.

For instance:

http://cwiki.apache.org/WICKET/documentation-index.html

appears to list many referential How to's but not core framework
architecture. I know there is a little bit in many of the reference samples.

But is there a paper on module architecture and core objects. Other than the
javadoc I mean.

Re: [Wicket-user] Adding extra row to table in ListView

Igor,

Yes, that makes sense.  However, I get the data for the list using a
single HQL query with joins and such. If I changed to a ListView
within a ListView, then wouldn't I also need to change to do many HQL
queries to build a bunch of small lists within a big list?  I don't
know what the performance implications would be of making this change.

Also, last night I was working on switching it to a DataView instead
of a ListView.  Could a single DataProvider supply the data for both
the outer and inner views?

Thanks!

Re: [Wicket-user] Good Tutorial on core wicket

i dont think we have something that is focused on the core architecture. if
you have specific questions we will be happy to answer them and maybe you
can compile them into a document.

it is hard to find time to work specifically on high level documentation
because this list, coding, jira, javadoc, etc take up a lot of time. by the
time someone gets to a point where they have enough knowledge to write such
docs they are usually buried in fixing bugs :)

Re: [Wicket-user] Test Case - Nested Forms/Models and weird behaviour

i guess you shouldve mentioned you are using 1.2.6, because nested forms are
1.3 and up.

what you can do is change:

class AddressForm extends Form to class AddressForm extends
WebMarkupContainer
and in AddressForm.html change form to div

then things should start working properly. of course the whole form will be
validated, when you press lookup. which is not something you want, but you
have to live with until you go 1.3 or create validators that only validate
conditionally.

ftp://ftpuser:[EMAIL PROTECTED]/wicket-quickstart-1.2.6.rar

The test procedure to reproduce strange behaviour is as follows.

appear to work apart from the extraneous postcodes)
4. Select second option from first drop down and hit use address (then all
addresses will be filled unexpectedly)

I suspect this behaviour relates to nested forms as without the outer form

it appears to work as expected. I am also beginning to suspect that this
may
be the root of my other problem with radio groups behaving oddly.

Hope this helps and thanks,
John

I am still having real trouble making truly reusable panels for domain
objects that work consistently without quirky behaviour.

I attach my code for an address panel. It contains a form as it has
buttons for looking up streets from the postcode. This panel needs to be
embedded with multiple instances in same page and/or other forms and
panels. The lookup etc works except it has some strange side effects.
When
I first enter a postcode and press the lookup button, all the other
postcode fields are populated further down the page. Then when I select
an
address from the now populated drop down list, and then press use
selected
button, all the remaining fields of all other address forms also get
populated!

This weird behaviour only occurs in a downwards direction thoughout the
page and only when the user has not already entered something in a
field.

Can people please look at the code below. I cannot see why it should
behave this way.

http://www.nabble.com/file/8180/AddressPanel.java AddressPanel.java
http://www.nabble.com/file/8181/AddressPanel.html AddressPanel.html
http://www.nabble.com/file/8182/AddressDO.java AddressDO.java

The form that adds these panels does it as below

The form has a compound property model has a pojo for its model object.
This is returned by getCreditCheckDTO().

Thanks in advance,
John

Yup got the one from trunk, and later I grabbed the one you mention (1.2)

Have sometrouble compiling it but I think its my machine thats acting up.

 where did you checked out gmap  sources from? trunk? 
 i dont know if any wicket 1.3 artifacts are deployed somewhere, but 
 you can checkout wicket source code as well and build it for yourself 
 as a quick workaround.

 or you can get gmap code from 1.2 branch, that depends on 1.2.* wicket 
 that is available on central repository for sure.

 Being able to deploy the artifacts to the central repo is something
 that is currently being worked on for incubator projects. Until that
 is sorted out, you'll have to do with the incubator wicket repository
 mentioned in the release notes.

Although I could write some docs after I get an Idea from the Book
Pro-Wicket or Wicket-Pro (don't remember just know) and migrate to 1.3,

so.

Re: [Wicket-user] DatePicker for a label


you will have to create a panel that contains a hiddeninputfield to capture
the input, the label, and the datepicker. then create javascript that wires
all these together.

Re: [Wicket-user] Good Tutorial on core wicket

2007-05-03 Thread Paolo Di Tommaso

Anyway Francisco is right, I'm also thinking that Wicket is really missing a
good tutorial about core concepts.

I'm not new to Wicket, I'm using it for about a year, but there still a lot
aspects obscure to me like PageMap, page versioning, details of page request
cycle and so on.

Wicket is really a good framework that covers every details of the web
application stack (and they are many and many not just web page rendering
..), but I'm thinking that a good tutorial about Wicket core concepts would
be very useful to novice users as well as experts.

Thank you.

   Under Firefox this works fine: clicking the Click Me link causes the

   The problem appears to be the wicket:head portion of the SubComponent.
   Comment this out and it works correctly on both IE and Firefox. Note

   Any thoughts?

[Wicket-user] Encountered issues during quickStack

2007-05-03 Thread Sebastian Hennebrueder

Hello,

I am evaluating Wicket and encountered some issues during development. I
found solutions by myself but post here my notes so that the docs may be
updated or the bug may be fixed.

In the helloWorld example you might consider to explain more precisely
that the webpage and the class are places in the same folder and must
have the same name. The first one is not at all common to a newbee.


Fix for AExampleAjaxCounter example. The modelChanged call was missing
and let to old page exception. here is a code snipped fixing the code.


 private Label label;
public Page1()
{
add(new Label(label1, This is in the subclass Page1));
 Model model = new Model() {
private int counter = 0;

public Object getObject(Component arg0) {
return new Integer(counter++);
}
};
add(new Link(link){

public void onClick() {
label.modelChanged();

}
});

Re: [Wicket-user] Adding extra row to table in ListView

Igor,

Upon further thought, how can a ListView inside a ListView solve this?
 Wouldn't the hierarchy cause the html to be messed up?  I can't have
TRs within TRs.  The inner listview isn't putting child data inside of
the TR, it needs to make TRs that are siblings of the outer listview.

The output should be like this:

table
tr wicket:id=groupView   --- Outer listview
  td wicket:id=groupTitle/td
/tr
tr wicket:id=dataView --- Inner listview
  td wicket:id=data/td
/tr
/table

Not like this:

table
tr wicket:id=groupView   --- Outer listview
  td wicket:id=groupTitle/td
  tr wicket:id=dataView --- Inner listview
td wicket:id=data/td
  /tr
/tr
/table

What am I not getting?

Thanks,
Tauren

Re: [Wicket-user] Adding extra row to table in ListView


you dont have to attach the listview to the trs though

in 1.2.6
you can attach it to span and do dataview.newitem(..) { return super.newitem
(..).setrenderbodyonly(true);

table
span wicket:id=groupView   --- Outer listview
  tr
td wicket:id=groupTitle/td
  /tr
  span wicket:id=dataView  --- Inner listview
 tr
 td wicket:id=data/td
 /tr
  /span
/span
/table

in 1.3 we have a placeholder that makes this easier

table
wicket:container wicket:id=groupView   --- Outer listview
  tr
td wicket:id=groupTitle/td
  /tr
  wicket:container wicket:id=dataView  --- Inner
listview
 tr
 td wicket:id=data/td
 /tr
  /wicket:container
/wicket:container
/table

advantage of wicket:container is that it will validate markup even at design
time, and it is stripped when strip-wicket-tags option is enabled.

rarely you do hit these cases where doing this in a jsp is easier because
the jsp renders top-down, but in my experience they are few and far in
between. and more importantly we have solutions to make them work.

Re: [Wicket-user] Adding extra row to table in ListView

Sweet!  I do have it working with an extra tag (where you use the
span), but I didn't like that it rendered invalid html.  Didn't know
about setrenderbodyonly.  Thanks for the tip!  When I move to 1.3,
I'll use the container approach.

Thanks Igor!

[Wicket-user] Is it possible to use setMarkupStream to assign html to a web page?

2007-05-03 Thread Thomas R. Corbin


I've got some groovy code which processes an xml file and generates some html.  
Right now I do it at build time, but would really prefer to do it at run 
time.   I've got some code hooked up which does so, but all I get is an empty 
page.

I'm using wicket 1.3.0-snapshot (prior to the name change)

when building the page, I run the following groovy code, where the buffer 
contains the html I generate.

MarkupParser  parser  = new MarkupParser( new XmlPullParser() )
Markupmarkup  = parser.parse( buffer )

def markupStream= new MarkupStream( markup )

page.setMarkupStream( markupStream )


I've tried overriding onRender in the page java code and calling 
renderComponent with my markup stream, but I still don't get anything 
showing.   It works with the same html generated at build time.

Am I way off base and this just won't work, or do I have some details mucked 
up?

Thanks,
Tom

see IMarkupResourceStreamProvider, there is also an example in

Re: [Wicket-user] Good Tutorial on core wicket

I'm not new to Wicket, I'm using it for about a year, but there still a lot
aspects obscure to me like PageMap, page versioning, details of page request
cycle and so on.

me too, I also think some more core concept needs more documentation, pro

[Wicket-user] RadioChoice with ajax in wicket 1.3?

2007-05-03 Thread jamieballing


I am getting an error that a RadioChoice control doesn't work via ajax... the
getInputAsArray() method on the FormComponent returns null. I did see a post
indicating that this was a bug in 1.2...

[ wicket-Bugs-1501513 ] RadioGroup/RadioChoice doesn't work with

Was this ever resolved? Does it work in 1.3?

Re: [Wicket-user] Good Tutorial on core wicket


Can we vote on this issue? can I call this an issue?

Igor gracefully pointed me to the Model article in the wiki, but this
article is mostly Object Structure, and How to Apply it... but lacks a
little on how is model updated and passed throughout the framework. It
surely taught me though. :)

Is it possible to ask understood community members to divide papers or small
overview articles on different aspects like the ones listed below?

And therefore we might have some good data to compile into a nice PDF
regarding Wicket's inner workings and architecture.

With a good paper like that one, the goal would be to auto-answer questions
like this one:

*Is it possible to use setMarkupStream to assign html to a web page?* 
(posted a minute ago by Thomas R. Corbin)

This is a question regarding inner workings, because the Answer is some
IMarkupResourceStreamProvider, and where is this information a part from
articles on How-To's.

Wicket is Awsome, this should be written on some paper showing architecture
and core components behavior.

regards to all,

Thanks.  I think I'll have to go with the build time option because the 
getMarkupResourceStream( container, containerClass ) method gets called 
before any code in my constructor has a chance to look at the PageParameters 
to find out where the xml file is to be able to build the html.

I don't see any way to delay the markup processing/loading until after 
I can

Re: [Wicket-user] Is it possible to use setMarkupStream to assign html to a web page?

2007-05-03 Thread Chris Colman

Sounds like a similar bug I had with overriding getVariation on WebPage.
This is now fixed in 1.2.6. The wicket authors had to rearrange the
ordering of initialization to ensure that my constructor got called
before the call to my overridden getVariation method. It could be that
they may have to do a similar thing for your case.

At the time I proposed a two phase initialization solution like most OO
frameworks have adopted: 

Phase 1: Constructors are called and allowed to return resulting in
fully constructed objects.

Phase 2: The framework calls 'init' on the fully constructed object - at
this point init will be working on fully constructed objects and so
avoid the issue I had and the issue you are having with parameters not
yet being processed and member data and relationships possibly not being
in the correct state.

The wicket authors prefer the current, single phase construction
approach, over a two phase initialization approach because it avoids the
task of writing 'init' methods but given that just about every other OO
framework I've ever used uses two phase initialization of objects I
think that wicket will continue to suffer bugs like yours and mine.

As wicket's popularity snowballs they're going to get more and more
propeller head users like you and me that have a great idea and then try
and implement it in wicket - often going where no man or woman has gone
before and pushing things to the edge of breaking. To date they've been
able to rearrange things under the bonnet to work around my issue and I
hope they can do that with your issue too but I fear that one day
someone is going to come up with a great idea that won't elegantly work
with a single phase construction/initialization mechanism. I don't know
how what the outcome of that would be.

 hrm. i would consider that a bug i think. i dont see why it would get
 called
 before constructor. can you set a breakpoint in there and paste the
 stacktrace please.

 they are planning on having chapters that cover this stuff. you might want
 to discuss that with them. maybe they are willing to add user contributions
 to the book on this, maybe not, maybe they are already writing about this.

 what we are available for is to answer specific questions. the rest is up to
 the users. we have the wiki, feel free to collaborate with others and ask us
 for clarifications/reviews.

 my 2c.

I agree. And as great as having better documentation would be, we're
still giving priority to this list, IRC and fixing bugs and
implementing improvements. So I'd say we're better at supporting our
current users, than making it easy for new ones to join in.

Best thing that can happen is just someone taking it up. Some users
have been very helpful with the Wicket (probably at least half of the
content is written by users, not team members), and that's really
great. Maybe someday someone will take up the job to write the
ultimate guide to Wicket. He/ she would should get all the help we
could give. :)

Hi,
   
We have a component with an AjaxSelfUpdatingTimerBehavior attached to
 it. When a certain condition is reached we want to remove the behaviour from
 its parent before updating it again, to prefent it from going on forever. We
 couldn't find a way for this. Component has a remove() method, but
 IBehaviour does not. What is the preferred way to do this?
   
Thanks in advance,

Re: [Wicket-user] Ajax Request problem with new window tabs (Wicket 1.3 snapshot)

2007-05-03 Thread RedFury


Hi,

Just checked out the latest code from 1.3 trunk, rebuilt my 1.3 and used it
in my project.  Problem is still happening for me.  Can you verify that the
latest source works for you when you run my attached test app and follow my
instructions?  If it does then  something is up because it definitely fails
the ajax for me.

thanks,
Dean

 Hi
 
 About the first problem, it should be fixed since yesterday. Could you
 please update your
 wicket to see if it really is?
 
 I can't reproduce the second one. I tested it with Firefox 2.0 on OSX
 and everything works as expected. I remember seeing something like
 this in 1.5. What FF version do you use?

 Ok I have spent a fair amount of time putting together a wicket example
 of
 my two problems.  It is a netbeans project but pretty bare-bones so it
 should be pretty easy to get working in other IDE's.  I have attached it
 here so if any of the wicket-gurus out there would take a quick look I
 would
 very much appreciate it.

 Basically there were two problems and this is how I reproduced them:

 Problem 1 - Ajax failing to update (requesting wrong page version
 maybe..?)

 Happens on all browsers (IE, Firefox, opera tested.)
 Open up firefox and paste app URL
 Click on Tab 3 (ajax request will put tab 3 up)
 Click back on Tab 1
 Open up second tab and paste URL
 Go back to first tab and look at Wicket Ajax debug.  Update is failling
 because the server is sending Component ID's which don't exist on the
 client.  They've got their pages mixed up.

 

 Problem 2 - Back button - Forward button failure

 Happens only on Firefox (I think) so maybe a browser problem ?
 Open up firefox and go to any site, I usually used google
 Paste app URL into browser.
 Click on Tab 3
 Click the back button to go back to google.
 Wait a while for page to 'expire'. Doesn't seem to take more than about
 30
 secs - 1min.
 Click forward.   Server is contacted and page reset, showing tab 1.
 Click on a subtab of tab1.  You'll get an error saying the page couldn't
 find the component/behavior, as if it still
 thinks it is on Tab 3 (?)

 Anyways, thats about all I can add for now.  If someone would be so kind
 as
 to have a quick look at the attached project and offer some feedback,
 that
 would be awesome.

 Cheers,
 Dean

  Sorry for replying to my own post, but I found another problem which
 seems
  to be related or the same thing.
  I'm not sure if its wicket 1.3 or my code but I'm going to try to write
 a
  simple app to demonstrate the problem then submit it here.
 
  Anyways, if I open my browser (firefox latest, fully updated) and start
 on
  a different, non-wicket page (say google)  Then go to my wicket app.  
 I
  have a bunch of ajaxed tabs which start out on tab 1 when the page
 loads.
  Each tab loads in a bunch of new html components in a panel, replacing
 the
  old panel.  So I click on tab 2 and new html gets ajaxed in, replacing
 a
  lot of the old components in tab 1.   Then I click 'back' to go back to
  the non-wicket page.  I sit on that page until the wicket-page has
 timed
  out, then click forward now.  Now the server loads my page again, and
 its
  reset back to its original form with tab 1 showing.  However, if I try
 to
  perform an ajax action within that tab, I get a server error telling me
  that it couldn't find the panel, because the server has got some weird
  state where even though it fetched me the reset page, it still thinks
 I'm
  on the modified page when I submit an ajax request.
 
  All this is very weird and probably doesn't make much sense without a
  solid example, so I'm going to try to put one together and hopefully
 some
  wicket guru can find out if its a bug or something I'm doing in my code
  which I shouldn't be.

  Hi Matej,
 
  I got the latest SVN trunk and it did indeed fix the 'session expired'

  My app has 1 main page, and everything else is loaded dynamically

[Wicket-user] Using AJAX wicketSubmitFormById like a method call

2007-05-03 Thread James Renfro

Hi,
I'd like to do something slightly unusual and wrap the 
wicketSubmitFormById call in another javascript function -- I'm able to 
do this with no problem by overriding 
AjaxFormSubmitBehavor.onRenderHeadInitContribution and calling 
JavascriptUtils.writeJavascript on a wrapped getEventHandler. I can stop 
the normal attribute for 'onclick' or whatever from appearing inside the 
component tag by overriding onComponentTag. And by using text input 
boxes, I can pass 'arguments' to my method on the server inside using 
FormComponent.getConvertedInput. So far so good.

The problem I have is that I'd like to actually 'return' a value back 
from the server in that Javascript function... so my function ends up 
looking just like a normal function call inside of my Javascript and 
returns the value that the server provides.

I can see inside of wicket-ajax.js that there are three special tags: 
component, evaluate and header-contribution, each with their 
appropriate purpose -- I tried messing around with 
AjaxRequestTarget.prependJavascript so I could pass something through 
the 'evaluate' tag, but my javascript isn't sufficient to the task. Then 
I tried using AjaxRequestTarget.addComponent to modify another TextField 
and return the value through the DOM tree -- that works fine except for 
the fact that the order is wrong, so my method returns _before_ the 
component is updated.

Then I noticed this interesting Wicket.Ajax.invokePostCallHandlers() 
call, which makes me wonder if there is already some nice clean 
mechanism in place for updating javascript variables thru wicket's java 
code.

Apologies if this all makes no sense, but any advice or suggestions 
would be much appreciated. The basic requirement is just that I make a 
call in Javascript and get data back from the server as a 'returned' 
variable on the client.

Thanks,
James

Re: [Wicket-user] Using AJAX wicketSubmitFormById like a method call


the short answer is: you cant do that. javascript is asynchronous, so the
request will start _and_ your function will continue running. usually what
is done is that you create a request object, and then register success and
failure handlers that are executed after the request is done.

you can do that using iajaxcalldecorator, or what you tried...calling
ajaxtarget.appendjavascript() should work as well.

if you show us some more code/try to describe your actual usecase we can
probably help you more, right now its all very abstract.

Re: [Wicket-user] Good Tutorial on core wicket


Right. I'll take this last mail to respond others as well.

Sorry to hear your book is still on production as I've read some great
articles and blogs and I was looking foward to reading the book.

But nevertheless it seams very positive that the reason is so many fixes and
upcoming good features.

To Scot. Thanks, yes I've read it. And it was helpful.

I'll still say that for me, the great magic behind wicket is inside of it,
and there is litle written about it. Great achievements in wicket, come, in
my opinion, from knowing how it works inside.

But I also agree 110% that priority comes first for helping others and
improving the framework.

best wishes,
frank

[Wicket-user] alternatives to set locale without using session?

2007-05-03 Thread ywtsang


Dear all,

I have read the wicket examples, wiki, mail lists, etc and it seems that if
I need to expliclity change the locale, i need to write codes like:

getSession().setLocale(my locale);



Now, I can determine the explicity language/locale need to use from the
incoming URL. 

I want to use wicket built in i18n support. My problem is, I cannot/will not
use session for nearl all the pages. 

So, any means to set the locale without using session? Any help/guideline
will be welcomed. Thanks.

Re: [Wicket-user] alternatives to set locale without using session?

you can override page.getlocale() and return something based on page
parameters. havent tried it but sounds like it should work.

Re: [Wicket-user] alternatives to set locale without using session?

2007-05-03 Thread ywtsang

One of the requirements of my project is not to use session, that's why my
question is so :)

Our website will have different language. Customers can choose for different
languages by clicking links like:

e.g.
/en/... (show english content)
/jp/... (show japanese content)
/kr/... (show korean content)
/zh/ (show chinese content)

Therefore I can deduce the language from the request link, it would be
nice if we can configure locale without the need of session creation.
