Re: Why has a cell item a model (and why is it a model with the populator (with the property) of the column)?

Hi Sven,

Thank you!

No, I was just wondering. I have not seen this model used.

Why has a cell item a model (and why is it a model with the populator (with the property) of the column)?

[Eric J. Van der Velden]

Hello,

I don't understand why a cell item gets a model, because I have not seen
where it is used. Only the model in the row item is used, together with the
property of the column.

Also why is the populator of the column in that model?


public abstract class AbstractDataGridView extends DataViewBase
@Override
protected final void populateItem(final Item item)
{

RepeatingView cells = new RepeatingView(CELL_REPEATER_ID);
item.add(cells);

int populatorsNumber = populators.size();
for (int i = 0; i < populatorsNumber; i++)
{
ICellPopulator populator = populators.get(i);
IModel populatorModel = new Model<>(populator);
Item cellItem = newCellItem(cells.newChildId(), i,
populatorModel);
cells.add(cellItem);
...

For example here we see that the row model + property of the column is
used, and not the model of the cell item:

public class PropertyPopulator implements ICellPopulator
@Override
public void populateItem(final Item cellItem, final
String componentId,
final IModel rowModel)
{
cellItem.add(new Label(componentId, new PropertyModel<>(rowModel,
property)));
}

Thanks.

Re: Cannot mock final SortableDataProvider.getSortState

[Eric J. Van der Velden]

Hoi Bas,

I am at the office now, so now I would like to comment on the first
question in your last answer.

My experience is that when you mock a class, and you call a final method on
the mock, Mockito returns null. So it is not that you can trust a final
method or not, the mock's method returns null. Or maybe I make a mistake.

It happens in OrderByBorder.onComponentTag. This method calls the
provider's getSortState(), which will return null. That is why I wanted to
mock this method, but I cannot, because it is final.

Thanks, I will comment on your other remarks later.

Re: Cannot mock final SortableDataProvider.getSortState

[Eric J. Van der Velden]

Hoi Bas,

Thank you for your answer!

So maybe I am doing it wrong.

Let's take an example. In the wicket examples, in package
org.apache.wicket.examples.repeater, there is the provider:

public class SortableContactDataProvider_my extends
SortableDataProvider_my<Contact, String> implements
IFilterStateLocator
{
...

protected ContactsDatabase getContactsDB()
{
return DatabaseLocator.getDatabase();
}

@Override
public Iterator iterator(long first, long count)
{
List contactsFound = getContactsDB().getIndex(getSort());
return filterContacts(contactsFound).
subList((int)first, (int)(first + count)).
iterator();
}

I mocked the iterator method. But you are saying that I should mock the
getContactsDB method?

Thank you.

Cannot mock final SortableDataProvider.getSortState

[Eric J. Van der Velden]

Hello,

SortableDataProvider, in
package org.apache.wicket.extensions.markup.html.repeater.util, has a final
method getSortState().

I cannot mock this method.

I have copied SortableDataProvider under a different name, and subclassed
this one,but I do not like this.

The same happens with final LoadableDetachableModel.getObject(), but in
this case I could mock LoadableDetachableModel.load().

So why are these methods final, and how do programmers test the provider?

Thank you!

The link Martin posted has a setContent() method for the ModalWindow that
takes a panel. 

So I have a different question:

When would you use a Page inside a ModalWindow, instead of a Panel?  It
seems like a Panel would be a better practice in most circumstances...

Hi Martin & Sven,

Thanks for your replies!

I ended up sending getPage().getPageId().  Is the better practice to use a
PageReference?  If so, I'll change my code to use that instead.

Secondly, I had no idea that you could use a Panel for the contents of a
ModalWindow.  I always thought you needed to use setPageCreator() of the
ModalWindow class, and provide a page.

It would make things cleaner if I could just use a Panel instead.  Can you
point me to an example?

Question About ModalWindows and IEventSink

[Aaron J . Garcia]

Hi Everyone,

ModalWindow has a "setPageCreator()" method, to set the page that you want
to display inside of the ModalWindow.

I've never used Wicket's event infrastructure, but I decided to use it today
to pass a message from the content of my ModalWindow back to the ModalWindow
itself.

Apparently, even if you use an event sink at the session or application
level, the event only broadcasts to components of the page that the event
originated from... A lot of Google searching took me to a post on the
mailing list that described that behavior, and let me to the below workaround.

I ended up using getSession().getPageManager().getPage(int id...) on my
content page to retrieve the page that contained the modal window.  Using
that as the event sink (instead of getSession() or Application.get()),
allowed the ModalWindow to consume my event...

Is it at all possible for one of the following "enhancements" to be made:

1) When inside of a ModalWindow, getPage().getParent() returns null.  Is
there a reason for this?  It would be *awesome* if getPage().getParent()
could return the ModalWindow that created the page.

2) I guess if 1) occurred, then events would properly propagate to the
ModalWindow when using a session or application level sink.

Thanks for your feedback.

Regards,
Aaron J. Garcia

Re: Performance Degredation for Adding Components in Wicket 7.0.0 vs. Wicket 6.20.0

Hi Martin,

Thank you for your reply.
 
Yes, 158 seconds is slow!  Instead of spending time profiling the issue in
our application-specific code, I made a quick-start.  It turns out that this
issue is very easy to reproduce with a vanilla RepeatingView component (as I
had suspected).

In summary, Wicket 6.20.0 adds 5,000 rows x 6 columns + 5,000
AttributeModifiers [one per row] (i.e. 35,000 add() calls) in about 200
milliseconds.  Wicket 7.0.0 takes about 10 seconds to add the same amount of
components to the hierarchy.  

With 10,000 rows x 6 columns + 10,000 AttributeModifiers, (i.e. 70,000 add()
calls), Wicket 6.20.0 takes about 500 milliseconds to add all of the
components, while Wicket 7.0.0 takes about 40 seconds.

In my opinion, this is a huge performance degradation from 6.X.Y to 7.X.Y,
and is something that should be looked at.  I created an issue in JIRA,
attached a quick-start, and marked it as Major issue.  In my opinion, this
should be moved to Critical or Blocker status though...  I'm sure I'm not
the only one who adds that many components or attribute modifiers to a page
at one time.

Thanks for your help.  You can reach me here or via e-mail if you need me.

Regards,
Aaron J. Garcia

P.S. I looked at your performance test, and I think it should try and add
more than 250 contacts to the page...

Performance Degredation for Adding Components in Wicket 7.0.0 vs. Wicket 6.20.0

[Aaron J . Garcia]

Hello,

I'm hoping someone here can help me.  My organization uses Wicket as the
framework for a fairly large internal web application.  

We have a page that renders a hierarchal data table.  It's implemented with
a RepeatingView for the table rows, and various WebMarkupContainers for the
columns (each column's component for one row gets attached to a new
WebMarkupContainer(rv.newChildId()) container).  Anyway, the table has about
1,000 rows, and 95% of them are collapsed via JavaScript when the page is
rendered.  Each top-level table row has a link to expand all of the sub-rows
underneath via a small JavaScript function to expand/collapse DOM elements
with a certain id.

This page has been in use since Wicket 1.4.X, and went through all of the
various 5.X.0 and 6.X.0 versions with no issues.  However, something changed
-- big time -- between Wicket 6.20.0 and Wicket 7.0.0.  In Wicket 6.20.0,
the server-side page rendering takes about 6s, with another second or two of
rendering the HTML in the browser.  In Wicket 7.0.0, this increases
dramatically to 158 seconds for server-side rendering (with the same one to
two second penalty for rendering in the browser).

I'm assuming that Wicket's internals changed a lot to support the new
Component Queuing functionality.  I'm wondering if maybe these changes
accidentally degraded performance for large component trees in a single Page
(which unfortunately, is our main use-case).  A colleague of mine put a
bunch of print statements in our code, and found out that some
WebMarkupContainer#add(); function calls were taking over 1 second each to
complete as the page is rendered (with performance degrading as more and
more components are added to the page).

Is anyone able to reproduce this issue, or hand any problems like this since
upgrading to Wicket 7.0.0?  I wanted to check here before trying to put
together a Quickstart...  Unfortunately, we are in a big crunch for the next
few months, so for the time being, we have just reverted to Wicket 6.20.0...
(and as a consequence, there's not much time allowed to spend debugging this
issue right now). 

Thanks for anyone's input and help.  I really appreciate it.

Re: More Wicket JSESSION_ID Issues

Hi Martin,

Sorry for the delayed response.

The URLs are identical in both cases: http://machine:8085/appName/ 

Wicket turns this into: http://machine:8085/appName/app/SignInPage

Intellij tries to open the first URL (http://machine:8085/appName/), but it
fails with this error message Cannot open URL. Please check this URL is
correct:.  When I copy and paste that same URL
(http://machine:8085/appName/) and paste it into my browser, it works fine,
and directs me to sign in page.  

(That's what I meant by sign of my page... sorry for not catching that sooner). 

What is interesting is that if I remove any of the JSESSIONID changes I made
(or downgrade to Wicket 6.13.0), everything works fine, and Intellij opens
up http://machine:8085/appName/ like I would expect.

-- Aaron

P.S. I don't need an immediate solution to this, because I figured out a
workaround yesterday.  I would like to get to the bottom of the issue
though, as the change in behavior is surprising.

More Wicket JSESSION_ID Issues

[Aaron J . Garcia]

I finally got around to upgrading to Wicket 6.14.0 yesterday.  With the new
changes in Wicket, I no longer get the exception spit out to the log when I
change the JSESSION_ID to JSESSION_ID_MYAPP.  Thanks for that!

I have another issue now:

When I run my app in my IDE (I use Intellij 13.0.2 and Tomcat 7.0.39), it
usually opens up a browser window for me pointing to the sign in page of my
app.  If JSESSION_ID is left alone, this behavior continues to work fine. 
Once I change my JSESSION_ID to something else, I get a message from
Intellij that says Cannot open URL. Please check this URL is correct:.  It
then shows the URL of my sign in page.  

Of course, if I navigate there directly, it comes up fine.  This is
perplexing to me.  Perhaps something in Wicket isn't playing nice with this
functionality?  This was all working fine with Wicket 6.13.0, so I don't
know what changed.

Would someone mind trying to reproduce?

Changed JSESSIONID Results in Wicket Exception

[Aaron J. Garcia]

Hi Everyone,

I maintain a Wicket application running on Tomcat 7.0.39, and I recently 
altered $TOMCAT_HOME/conf/context.xml to include a sessionCookieName 
parameter.  I made a change like this:


Context sessionCookieName=JSESSIONID_MYAPP

This properly changes the session cookie that is used by Wicket to 
JESSIONID_MYAPP instead of JSESSIONID.  However, when I start up my 
Wicket app, I get the following error spit out to the logs in 
Development mode, when running in Intellij.  Any idea why?


When I was using the normal JSESSIONID, it was properly ignoring it when 
it was appended to the classname for the SignInPage.

This doesn't work for me.  Looking at the source for WicketObjects.java

Should I open a JIRA issue for this change?

Thanks Martin,

FWIW, I was setting this when running Tomcat:

-Dwicket.jsessionid.name=JSESSIONID_MYAPP

It didn't work with the -D option, so I added it to my class that extends
WebApplication, like so:

System.setProperty(wicket.jsessionid.name, JSESSIONID_MYAPP);

and that didn't work either.

I'm happy to help pinpoint the issue however I can.  Please let me know.

Wicket 6.0.0 Issue: RadioChoice with AjaxFormChoiceComponentUpdatingBehavior

[Aaron J . Garcia]

Hello,

I just wanted to report an issue I encountered with Wicket 6.0.0 (there already
is a JIRA issue about it).

https://issues.apache.org/jira/browse/WICKET-4769

When you attach an AjaxFormChoiceComponentUpdatingBehavior to a RadioChoice
inside of a form, clicking on the label of an item doesn't select it's
corresponding radio button.  This was working fine in Wicket 1.5.8, and is
annoying in the sense that you need to click on the radio button (and not the
label), to get the corresponding Ajax behavior to occur.

Does anyone know if this can or will be fixed for the next maintenance release?

Thanks a lot for your help!

AjaxEditableLabel Missing setConvertEmptyInputStringToNull(...)?

[Aaron J . Garcia]

I am wondering if AjaxEditableLabel is intentionally missing a
setConvertEmptyInputStringToNull(...) method?  I have a use case for it, and it
seems like it would be reasonable to implement.

For now, I have a work-around for this by overriding AjaxEditableLabel's
newEditor(...) method.  However, I don't like this solution because I need to
cast the returned FormComponentT into a TextFieldT in order to get access to
the setConvertEmptyInputStringToNull(...) method.  If the underlying newEditor
implementation is changed at some point, my code won't work.  

Can this functionality be added to AjaxEditableLabel?  If so, how would I go
about requesting it?  

Thanks a lot for your help. 

Regards,
Aaron J. Garcia

Skip session creation when AjaxLink is disabled

[J]

I have a page that has two states:
-user logged in (session creation allowed)
-no user logged in (no session creation allowed, otherwise bots will crash the 
server by exploding session creation)

When a logged-in user requests the page, the page should be render with 
AjaxLinks visible (which will cause sessions to be created).
When a non-logged-in request comes in, the page should render without AjaxLinks 
visible. How can I achieve this last situation (disabled AjaxLinks) while 
avoiding sessions?

  how is wicket supposed to build a url to your anonymous reference

  you have two options, use renderCssReference(String url) to output the

Re: Demystifying page serialization

[J.-F. Rompre]

Mike, in reference to your various questions, here is my take:

You are not seeing your constructor tracing print statements because it is
not invoked more than once (the page object is already in the page store,
with its component attached as per the constructor invocation) - all
components are the same, but the data can vary depending on your model as
observed. This is the case
for stateful, or non-bookmarkable pages.

Bookmarkable pages are re-instantiated and must be given their state if any,
at construction time.

That is how Wicket decides whether to go back to the page store or use a new
instance. I believe Bookmarkable links are there to accomodate fast access
to stateless pages or stateful pages with the state encoded in the request.

Re: setRenderBodyOnly with ListView and attributes

[J]

That will work, but I already knew that.

The whole problem is that it violates Wickets just/pure HTML philosphy in 
that an extra unwanted div (or span) is required in WickedHTML just to make 
ListView work, even though it's a common scenario.
If ListView would follow Wickets philosophy, it would support this WicketHTML:
div wicket:id=products class=products
 div wicket:id=product class=productProduct1/div
/div

At the moment, there are two known workarounds in this discussion:
1) Accept the violation of just HTML by using the extra DIV.
2) Accept the violation of just HTML by using wicket:container.

Re: setRenderBodyOnly with ListView and attributes

[J]

A feature/philosophy is that Wicket HTML is just plain HTML.
This means that a webdesigner can create plain HTML, annotate it with wicket:id 
attributes, and then the Java developer can just write Java code.
Plain HTML can be transformed to WicketHTML just by adding wicket:id attributes.

In the case of my problem, which is a very common scenario, you cannot just add 
wicket:id's, and let it work. It requires the use of extra divs (or 
wicket:container) just to let ListView work. The extra required div causes a 
difference between the plain HTML and WicketHTML, and therefore for WicketHTML 
the HTML rules differ.
The designer now has to know about these details of Wicket, such as: if the 
developer is going to use a ListView, the developer has to wrap extra divs 
around some elements.

setRenderBodyOnly with ListView and attributes

[J]

hi, I want to have Wicket to generate the following HTML precisely:

div class=products
 div class=product./div
 div class=product./div
 div class=product./div
 div class=product./div
/div

But with my code, I don't get further than:

div
 div class=product./div
 div class=product./div
 div class=product./div
 div class=product./div
/div

so the class attribute is missing in the outer div.

My Wicket HTML is:
div class=products wicket:id=productsView
 div class=product wicket:id=productPanel./div
/div


My code:
ListView productsView = new ListView(productsView, products) {
 protected void populateItem(ListItem item) {
 item.setRenderBodyOnly(true);
 item.add(new ProductPanel(productPanel, item.getModelObject()));
 }
};
add(productsView);


What is the Wicket way of achieving this?
(A solution is to use the wicket:container tag, but that's a bit ugly, right?)

 I made a mistake in my first post. The output of wasn't:
 
  div
  div class=product./div
  div class=product./div
  div class=product./div
  div class=product./div
  /div
 
  but it was:
  div class=product./div
  div class=product./div
  div class=product./div
  div class=product./div
 
  So the outer div is missing.
  Which is caused by item.setRenderBodyOnly(true). But if I disable (set to 
  false) this (the default), I get:
 
  div class=productsdiv class=product./div/div
  div class=productsdiv class=product./div/div
  div class=productsdiv class=product./div/div
  div class=productsdiv class=product./div/div
 
  which is even worse.
 
  A solution (the only?) to this double div problem and at the same time the 
  missing attribute problem, is using wicket:container tags. (see 
  http://apache-wicket.1842946.n4.nabble.com/Panel-in-List-remove-extra-div-td1877053.html
   )
  This leads to this solution:
 
 
  div class=products
  wicket:container wicket:id=products
  div class=product wicket:id=productPanel./div
  /wicket:container
  /div
 
  Wicket:container tags make it ugly imo, because it violates wickts just 
  HTML philosophy, even though my problem is a very common scenario.

   It defeats the purpose of having HTML in Wicket. But there probably is

WicketFilter doesn't chain?

[J]

I'm having some problems with 
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter in some 
cases. I did some debugging and found that 
org.apache.wicket.protocol.http.WicketFilter isn't doing ServletFilter 
chaining: when it is called when a Wicket page is requested, it is breaking the 
filter chain by not calling the Filter.doFilter method (from Servlet API), 
causing other filters defined in web.xml not to work within the same 
url-pattern. (A workaround is to define WicketFilter as last entry in web.xml.)
When a non-wicket url is called within the same url-pattern, then WicketFilter 
does perform a doFilter, allowing other filters to do some work.

In Servlet applications (which Wicket basically also is), I think it is 
expected behaviour that all filters within some url-pattern should always be 
called. But WicketFilter seems to break it. Is this expected behaviour?

TabbedPanel: tab visibility

[Metzger, Natalie J.]

Hi all,

Maybe I'm blind, but is there a way to set the visibility of certain tabs in 
the TabbedPanel? I only found the method isVisible(), but no setVisible(). My 
goal is to have certain tabs only visible to users with corresponding 
permissions. So far I have to add/remove tabs depending on those permissions, 
and which is less than optimal.
And yes, I can change the visibility of the content of the tab, but this is not 
what I need.

Any ideas?

Thanks,
Natalie

Re: how to make a wicket web editor

[m j]

Well, if you know how to use JQuery you can hard code the javascript and
html into the page, which is pretty easy and obvious as it just goes into
the HTML.

The other option if your familiar at all with Wicket is to put it into a
panel to allow more control and usability.

Wicket button label

[Metzger, Natalie J.]

Hi all,

I'm comparatively new to Wicket and have a question about the wizard button 
labels. I'm using a Wizard with an AjaxButtonBar and AjaxButtons for previous 
and next. I would like to change the labels on the last step of the wizard of

any elegant solution to this?

Re: images not under the context root directory

[Matthew J]

Question, as I am dealing with a similar issue, except I save my file  
to my glassfish directory (ie: glassfish/domains/domain1/uploads/ 
Videos/...). I can't seem to find the url though I have tried many  
different types of urls...


For the record
((WebApplication 
)WebApplication 
.get()).getServletContext().getRealPath(newFile.getCanonicalPath())

returns:
/Users/msj121/NetBeansProjects/WebBuilder/dist/gfdeploy/WebBuilder/ 
WebBuilder-war_war/Applications/Programs/NetBeans/sges-v3/glassfish/ 
domains/domain1/uploads/Videos/...



btw, for those using Glassfish you can have urls to physical hard  
drive space even not in the context root by using an alternatedocroot  
(ie: alternatedocroot_1 from=/uploads/* dir=/).



I assume my directory is in the context root and I should be able to  
find it, no?

Serialization on objects inherited from a container

[J.-F. Rompre]

Hello,

I would like to know where I could find documentation on the issue of
serializing objects inherited from a component's container as in the example
below. I tried looking at the wicket source code to see when this occurs but
still don't understand when/how it is done.

//...

final Product p = //get non-serializable Product object

add new Link( addToCart) {
public void onClick() {
getSession().getCart().add( p.getId());
//..etc

The above throws a NotSerializableException. However, no problem occurs
after the code is changed to:

//...

//Product p already assigned
final String pId = p.getId() //serializable

add new Link( addToCart) {
public void onClick() {
getSession().getCart().add( pId);
//..etc

(Also, building the Link with a wrapping Model object also works, obviously)

However I am curious to know why a non-model object is serialized when
inherited from the container even though within the same request?

Thanks for any comment,

JF

Re: Stateful vs stateless requests and navigation

[J.-F. Rompre]

Thank you Igor - I hadn't turned the logs on. Making the domain serializable
fixed the issue. I didn't think this would happen because I am using
LoadableDetachable models passed to a list view - probably serializing to
produce list items - will see if individual items can be fetched from cache.

 SETUP A
  So I tried setting the response headers to 'no-cache','no-store' as

  However all stateless- requests such as paging URLs got rejected with
 'Page
  expired', even though the session is obviously live (versions keep

  incremented

 this should work without problems. are you sure there are no errors in
 your logs? the page should not be expired. feel free to create a
 quickstart that reproduces the problem and attach it to a jira issue.

 SETUP B
  Next I tried URLHybridCodingStrategy combined with the 'no-cache',
  'no-store' header config. and that removed the 'Page expired' problem.
  However, I still can't access the previous screen when it was accessed
 with
  a stateful request such as pagination: instead, the user is sent back to
 the
  beginning of the pageable list.
 
 
  Also, with my current setup B above, I am expecting page instances to be
  reused when accessed within a session: however new page instances are
  created for each single request except for pagination requests - those go
 to
  the latest version, I assume.
 
 
  So my question is two-fold:
 
  1) Does setting no-cache and/or no-store in the header cause the page map
 to
  keep only the current version, or older verions to be inaccessible via
 the
  request URL?  I know that 'Page Expired' can have other causes e.g.
  serialization issues, but if that was the case here then setup B would
 have
  failed as well? Unless the problem exists in both cases both is 'skipped
  over' by the HybridUrlCodingStrategy?
 
  2) What drives the decision to reuse page instances, other than
  non-bookmarkability?
 
  Any comment or pointer to existing documentation is greatly appreciated.

 if you are instantiating components with the same state then you

Re: How do I reuse a rendered string, i.e. render once and past in multiple locations, e.g. paging nav at top and bottom?

[J.-F. Rompre]

OK, thanks Martjin and Jeremy - I think mentioning performance was a mistake
on my part..let me try again.

I am not trying to couple different components, only to reuse what I know is
never going to change within the same rendering - actually, avoiding the use
of multiple component instances of the same subtype where a single instance
would suffice.

My question is: Is it possible to capture a rendered string for reuse? In
other words, if I have a component subtype that I am currently instantiating
multiple times with exactly the same state (therefore the output is exactly
the same), is it possible to render it once and once only and reuse the
string from that rendering within the same container or page?

At this stage I am only trying to know how to do something instead of why
(optimization or other reason, such as saving markup coding, or some other
reason). I went through the source and searched on forums as well to find
out, but didn't.

My apologies if that question has been answered elsewhere - please let me
know where I can look.

Thanks,

JF

 WHY?  It's premature (and almost certainly unnecessary) optimization.
 Doing it needlessly couples multiple components together - reducing
 reuse.

 As always, we are more than interested in seeing any results of
 performance analysis that you have done that says that this will
 reduce your page load time by any significant factor.

Form Submit with non-serializable Model

[J]

I have a non-serializable User object that must be created when someone 
registers for an user account.
The problem that I have with my current code (below) is that the 
ModelObject in onSubmit() doesn't have the username property 
bounded/pushed to it, so it's null.
This problem doesn't occur when I use a serializable User object with a 
normal inner Model.


What is the Wicket way to fix this problem without having to make the 
User object serializable, and without having to manually access the 
formComponents to retrieve the values?




public class RegisterPage extends WebPage {
   
   private class User {

   private String username;

   public String getUsername() { return username; }
   public void setUsername(String username) { this.username = 
username; }

   }
   
   public RegisterPage(final PageParameters pars) {


   IModel userModel = new CompoundPropertyModelUser(new 
IModelUser() {

   private transient User user;
   
   @Override

   public User getObject() {
   if (user == null)
   return new User();
   return user;
   }

   @Override
   public void setObject(User user) {
   this.user = user;
   }

   @Override
   public void detach() {
   user = null;
   }
   });
   setDefaultModel(userModel);
   
   FormUser form = new FormUser(registerForm, userModel) {

   @Override
   public void onSubmit() {
   // This one prints null instead of the username.
   System.out.println(getModelObject().getUsername());
   }
   };
   add(form);
   
   form.add(new TextField(username));

   }
}

Code identation was a bit messed up. Maybe this copy/paste is a bit better:

   private String username;

   public String getUsername() { return username; }
   public void setUsername(String username) { this.username = 
username; }

   public RegisterPage(final PageParameters pars) {


   IModel userModel = new CompoundPropertyModelUser(new 
IModelUser() {

   private transient User user;
  
   @Override

   public User getObject() {
   if (user == null)
   return new User();
   return user;
   }

   @Override
   public void setObject(User user) {
   this.user = user;
   }

   @Override
   public void detach() {
   user = null;
   }
   });
   setDefaultModel(userModel);
  
   FormUser form = new FormUser(registerForm, userModel) {

   @Override
   public void onSubmit() {
   System.out.println(getModelObject().getUsername());
   }
   };
   add(form);
  
   form.add(new TextField(username));

   }
}

You didn't set user = new User(), so when the form updates your model,
it's not updating the user stored in the field, but rather one that
only lives for the duration of the form processing, and then your
onSubmit is checking the one represented by the field.

So change the above to:

if (user == null)
   user = new User();
return user;

and it should work.

Validation on Beans

[J]

hi,  I'm using Wicket, Spring and Hibernate, and would like to have bean 
validation declaratively defined in the beans instead of in Wicket UI 
components. Hibernate has a bean validation framework called Hibernate 
Validator, and Spring has validation framework that is part of the 
third party Spring-Modules. Both use validation by annotating the beans.


I like this approach, but how can I use it with Wicket?


Cheers,
J

(Sorry for the empty message. First I tried Gmail, but that doesn't work
with this mailing list. Then I tried GMX webclient, but that client always
sends as HTML, which probably caused the message to be stripped to empty.)


I'm experiencing freezes on a production website.

Server specs:
-OS: Linux CentOS
-Webserver: Tomcat 6
-MySQL 5 with default settings
-Frameworks: Wicket 1.4-rc2 (webframework), Spring 2.5.6, Hibernate
3.3.1.GA, C3P0 db pooling 0.9.1.2, URLRewriteFilter 3.1.0, Spring
OpenSessionInViewFilter 

Problem:
At some point (about 5 to 24 hours) after a boot, Tomcat seems to stop
serving requests, although it does create new threads for new incoming
connections. But since it does not serve those connections, the new
connections will show and keep showing 0kb transfer. Shortly after that,
max-thread is reached, so then I'm unable to access any webapp (the main
website + tomcat manager) running on that Tomcat server. I'm not sure if it
is able to serve static resources in the short time window where it still
has some threads free, because the time window is too short to notice when
it happens.

Observations:
-No exceptions or errors in the catalina logs. So no memory problems, since
no error occurs in the logs
-Java Thread dump using command: kill -QUIT (see output below), shows the
text locked and WAITING.
-Adding c3p0 db pooling idle checks, tests and timeout settings (see below)
did not help.
-Using Mysql Administrator GUI shows that after a freeze, there will be 15
threads, all sleeping. Normally this would return to a minPoolSize of 5, if
I'm correct, but thats not the case.
-The freeze continues for hours, and does not recover. I have to restart
Tomcat.


I'm suspecting that it has something to do with DB pooling. I'm not sure if
locked and WAITING are normal behaviour. But if there is something
wrong, why doesn't c3p0 recover from it?

Can somebody shed some light on this? :)

RE: WebApp Freezes

-MySQL 5 is configured using defaults, which is max_connections 100
-Tomcat is configured with maxThreads 150
-C3P0 is configured with maxPoolSize 15

I'll increase C3P0's maxPoolSize to 90, to see if that makes any difference
in the occurences of freezes. Most of Tomcats threads are used to serve
static resources (running in a different webapp) that don't use a db
connection at all.

your max database connections should mirror the max request threads of
tomcat. Otherwise you'll endup in deadlock country...

Also make sure you don't have deadlocks in your database.

The lack of errors in your tomcat logs don't necessarily mean there
are no memory problems. Check with jstat -gc pid if your garbage
collector is having problems.

Not just one thread, but that thread dump part (from my first post) is
repeated for 149 other threads have the same situation. ( because of tomcats
150 maxthreads).

But when looking at the db during a freeze, there is no lock on any table at
db level. MySQL Administrator shows that there are 15 threads during the
freeze (equal to c3p0's maxPoolSize), all sleeping.

I have now added some C3P0 debug and workaround options to see if I can get
some extra info out of it.

Sounds like you have a thread holding a lock on a critical table and
subsequent threads are lining up behind it waiting for it to finish. You
should check your MySQL to try and figure out who's holding the lock and
why.

Note that the culprit thread need not be hung up in the database. Locks
are held until the transaction commits, so your thread could be hung up
in app code after making a database update but before the transaction is
committed.

It's not a simple thing. A huge amount of time (both for
implementation and testing) went into the current modal window library
to make it work as cross-browser as possible. Unfortunately, I wasn't
aware of all the exotic use cases people want so the library is rather
monolithic. There is a rewrite on my to-do list that would split the
modal window into pieces (mask, basic window, style, etc.), but it's
not really a high priority.

Modal dialogs with Ajax

[Anthony J Webster]

Hello again,

I have a form with ajax validation on its component's 'onblur' and a sumit 
link. The submission process takes a while as it results in numerous database 
lookups and so on. Initially I used an IndicatingAjaxSubmitButton to show the 
user that their request was being processed, with the help of mailinglist and 
#wicket members I also disabled the link during the submission with an 
AjaxCallDecorator and I suppose I could always add a modal div over the whole 
site as well (in the same callDecorator) in order to stop users changing the 
form contents or navigating to another part of the site.

That all works fine however I need to push this further. If a user submits 
information which corresponds to a object that already exists in the database, 
I need to ask him whether he wishes to create a duplicate.

The way I see this working is as follows. The user submits a valid form by 
clicking the link. This results in a modal centered dialog with some loading 
animation being displayed. If the submission works the user is redirected to a 
'success' page where the entered data is display along with any information 
calculated during the submission. However if there is an error (an Exception 
thrown from the server) either a connection problem or duplicate data, the 
animation is replaced by some text explaining the problem and 1 or 2 buttons 
(Cancel for connection problems and Make Duplicate/Cancel for duplicate data). 
The Cancel button simply removes the modal window effectively returning the 
user to the form, whereas the Duplicate button launches the submission again 
and displays the animation until it succeeds or fails again in the case of 
connectivity problems.

I know this a lot to ask but has anyone got any idea how to achieve this as I'm 
getting a tad confused!

Many Thanks

Anthony

ModalWindow customisation ?

[Anthony J Webster]

Hi,

Is there any way to customise the actual frame of a ModalWindow? Preferably I'd 
like to get rid of the frame entirely or just replace it with a simple box of 
the same colour as the enclosed page/panel without the top-right close button.

Any ideas?

Many Thanks

Anthony

Re: ModalWindow customisation ?

hmm it uses image maps for the frame graphics :/
I suppose I could rewrite it and strip it of most of its functionality

AjaxSubmitLink does nothing in IE

[Anthony J Webster]

That works fine. Thanks
However I've just noticed that this AjaxSubmitLink doesn't do anything in IE 
whereas in Firefox it works.
I check the Ajax debug window and the server *is* contacted and everything 
however after recieving the response I get an ERROR: Error while parsing 
response: Unknown runtime error in IE.


Any Ideas?

Hi folks,

Cemal and I have been working hard refining jWeekend's upcoming Getting 
Started With Apache Wicket 1.3 [1] and Apache Wicket 1.3 [2] courses. 
The next ones are scheduled for September 22nd and September 29th-30th 
respectively.


They're an excellent way to get up to speed with Wicket and develop an 
in-depth understanding of Models, Behaviors, the AJAX functionality, 
advanced validation, etc., etc. As such, they will be useful to you 
whether you're a beginner or a fairly seasoned Wicket programmer, so I'd 
encourage you to visit the jWeekend site [3] for more information and to 
see just what you'll be getting (and hopefully to book your place ;-) ).


Hope to see some of you there!

We have helped people from out of town with accommodation (for the

We have had excellent feedback about our last Wicket course (2 day), and 
we

believe we have further improved the material for our 2 new 1 day Wicket
courses and our original 2 day course (all now based on 1.3), with Al

Houdini FeedBackPanel Problem

[Anthony J Webster]

Hello,

I'm having some trouble with FeedbackPanel. I have an ajax validated form and 
submit button. Whenever a component looses focus it and the others are 
validated and if there are errors these are displayed in the single 
feedbackpanel abover the form. This works fine however I have a problem when 
submitting with my AjaxButton. There is a lengthy method call in 
AjaxButton#onSubmit() which (as it contacts other servers) mail fail. If an 
exception in thrown I call error() in order to show the user that the 
submission process has failed. This call works, however most of the time I only 
see the error message for a split second. When I submit by pressing enter it 
seems to work OK.

I think his has something to do with the componenet focus and have been trying 
to decern a pattern in this behaviour but so far despite numerous re-workings 
the feedbackpanel behaviour remains the same.

I have uploaded a small quickstart project demonstrating this problem over at 
http://www.transcendenz.co.uk/quickstart.zip and I would be most grateful if 
someone with greater Wicket knowledge than I could have a quick look and tell 
me what I'm doing wrong.

Many thanks in advance,

Anthony

Re: Houdini FeedBackPanel Problem

[Anthony J Webster]

D'oh. Ignore the javascript. I was testing sometning and it would seem I 
forgot to remove it all before uploading the quickstart.


Is there a way I can register my error as a regular validation error from 
the onSubmit()? Or somehow deactivate the validation behaviour until after 
the submission error is displayed...


Thanks

Hi,

there are multiple problems with your code. First you have
   script type=text/javascript
 document.getElementById('a').
   /script
In your page's header. That's a javascript error (trailing .).

Also you've attached validating behavior in onblur. That's the behavior 
that

clears feedback from your panel. Your problem is that the error message is
registered only during onSubmit(), but not during regular validaiton. In
wicket, all validation message sare supposed to be displayed only once. So
when you submit your form, the message is registered, and if after that 
for

any reason onblur is triggered, it clears your message.
