Re: [Wicket-user] Betr.: Write javascript to inlineframe

2007-06-25 Thread Marieke Vandamme


Yes, the writejavascript lines are indeed in the inlinepage constructor. 
In my example the code isn't inside InnerPage.html but inside
InnerPage.java. My mistake.
Thanks !

constructor is the wrong place to write that kind of output because it might
end up before html tag. you should use iheadercontributor to write
javascript so it goes into the head element.

   private static Map getClassesToGetAndSetters()

   return (Map)applicationToClassesToGetAndSetters.get(Application.get

Re: [Wicket-user] NPE in PropertyResolver

2007-06-25 Thread Johan Compagner


maybe we shouldn't store the class itself at all:

   Map getAndSetters = (Map)classesToGetAndSetters.get(clz);
   if (getAndSetters == null)
   {
   getAndSetters = new ConcurrentHashMap(8);
   classesToGetAndSetters.put(clz, getAndSetters);
   }

but do put(clz.getName(), getAndSetters)


hmm, on second hand that wont help a bit, because we need to keep references
to fields and methods anyway.

Yeah, this was my rationale - it makes all the look-ups much slower, and 
if you WeakReference or String-reference the class, you need to build a 
custom key for method signatures and all the rest of it (Methods and 
Fields can't be WeakReferences as they'll be garbage collected behind 
your back).

Going back to Jonathan's original unit test case, I'm thinking maybe we 
can lazy-init this to make unit testing more bearable.

Otherwise you need to have an MockApplication, etc.

stage directions: Al goes off to make it so... /

[Wicket-user] Foldable border

2007-06-25 Thread Stefan Kanev


Hello.

I'm trying to create a foldable box component - not unlike the quick
contacts and labels boxes in gmail. I want to render some markup around a
border's contents - particulary, an open/close link. So far, I've made it
toggle the value of Border.setBorderBodyVisible() and it works fine.

But. I also want to skip the loading of the contents of borders, that are
initially rendered closed. I though the deal would be to just
borderBodyVisible to false and not to put any components in it at all, but
unfortunatelly wicket raises an exception that components with coresponding
names cannot be found in the hierarchy. This was not the behavior I was
expecting, since after Component.setVisible(false) it doesn't check the
markup for matching components.

Can anyone help me resolve this issue? I'm using wicket 1.3, if it matters.

[Wicket-user] Wicket 1.2.4 - Cross session concurrency issues

2007-06-25 Thread Seldon, Richard

Hello all, 
 
Further to email sent out back on 15/06/07 regarding concurrency issues
using Wicket 1.2.4 and load runner...
 
Really keen to know best place to get a list of outstanding defects between
releases wicket 1.2.4 and 1.2.6  is located? Are there release notes / URL
links etc with this info easily available? Apache issues list starts with
version 1.2.7 but this is no good in our case.
 
Our concurrency problem can be reproduced without load testing s/w and
(after exhaustively going through all our static code usages and other
possible areas of contention) likely explanation now sits with the version
of Wicket we're using. The Wicket website does include a section about a
critical bug in 1.2.4. In our case, if this is the problem, then it has
proven to be a show-stopper.
 
We are hoping to go live with our production release of SOA app in next few
days and have concluded we may need to either go with 1.2.6  (if the
migration is proven to fix our defects in test environments) or apply a

[Wicket-user] AJAX causing UI state corruption....

2007-06-25 Thread Seldon, Richard


Hello all, 
 
Further to email sent out back on 15/06/07 regarding concurrency issues
using Wicket 1.2.4.
 
Really keen to know best place to get a list of outstanding defects between
releases wicket 1.2.4 and 1.2.6  is located? Are there release notes / URL
links etc with this info easily available? Apache issues list starts with
version 1.2.7 but this is no good in our case.
 
Our concurrency problem can be reproduced without load testing s/w and
(after exhaustively going through all our static code usages and other
possible areas of contention) likely explanation now sits with the version
of Wicket we're using. The Wicket website does include a section about a
critical bug in 1.2.4. In our case, if this is the problem, then it has
proven to be a show-stopper.
 
Another point I'd really like to hear discussion about:- we're using WID
version 2.0.1.2 which provides support for Java 1.4. At present, this limits
us up to Wicket 1.3 - will there be ongoing maintenance support for users

I recommend you to use wicket-1.2.6. This version is better and have some
useful fixes, including ajax related. Regarding the transparency issue, I
recommend to use the  http://malsup.com/jquery/block/ jquery.block plugin ,
or at least take it as an example for your own js implementation. I have my
own light version of this plugin..

 Sure Alex, what i meant was that in order to get IFRAME to be transparent
 i
 tried a combination of setting allowtransparency=true as an attribute on
 the IFRAME element and then in css class definition for the IFRAME put in:
 filter:progid:DXImageTransform.Microsoft.Alpha(style=0, opacity=0);
 Alpha
 handles opacity allowing effectively transparency for the underlying page
 content (didn't work with select form component though). 
 
 Note IE worked for textfields (input type=text) html form components
 with
 these settings. it was the select that failed. Below is an example snippet
 code with z-indexes to illustrate this point. the z-index  is a constant

   getindexes();

 function getindexes(){
 
   text1.value=div1.style.zIndex;
   text2.value=select1.style.zIndex;
   text3.value=5;
 }
 /script
 /HEAD
 BODY onload=getindexes()
 
 Div
 input type=text value= id=text1 name=text1 p
 
 Select
 input type=text value= id=text2 name=text2p

 Can you explain what do you mean by  but iframe transparency issues 
 meant
 access to underlying
 form component.? 
 
 I am using option 2 to avoid UI state corruption and didn't have any
 problems with it.

Click on the 'Releases' tab and you can see *all* releases. Then you
have release notes for 1.2.5 and 1.2.6:

Not knowing the details of your concurrency problem, I would urge
anyone to upgrade to 1.2.6, because of the security implications of
said bug.

Now that you have it reproducable, could you provide a
quickstart/other test so we can fix it? And before that, use 1.2.6 to
see if that fixes your problem?

We are hoping to go live with our production release of SOA app in next few

What is preventing you to upgrade to 1.2.6?

JDK 1.5 is already 2 years available. We have held off developing 1.5
features for long enough IMO.

That said, we will support Wicket 1.3 for bug fixes, and possibly some
features will be backported (portlet support may be one such feature),
but that is based on available interest, and the impact of said
feature on 1.3. Usually we shy away from API breaks, providing a
binary compatible release on maintenance branches. And yes
*eventually* we will stop support for 1.2 and 1.3 as technology
progresses: this is a volunteer project and we only have limited time
and resources.

If you are anxious with respect to support for older versions, you
might want to consider paid support. Wicket Support
(http://wicket-support.com) will be happy to give you options.

As developers, we're definitely pro-Wicket but getting nervous regarding
this project's usage of Wicket and outstanding defects. Especially with
migration route options outlined above.

I really don't understand what you are saying here.

Guys, thanks for the answers but I don't think I explained my self.:

I understad this is a solution. But how may I better defend models in
general.

What would be the purpose of a class with only getters and setters besides
adding a new layer to the software?

public class Person{
  String firstName;
  String lastName;
  public Person(){
  }
  public String getFirstName(){
 return firstName;
   }
   public void setFirstName(String firstName){
  this.firstName=firstName;
   }
   etc...etc..
}

also create anl XmlCompoundPropertyModel(String xml) and you can do

wicket can bind to anything, not just pojos.

Well (in the absence of further information), there would be no purpose. 
But there's no need to have these extra objects in the first place.  If your
services are written in Java, just use the pojo BOs (or DTOs) returned by
these services as your model.  If your services are written in some other
language (C++) and return xml-serialised versions of BOs/DTOs, then just use
the xml as the model (as Igor explained).  No need for another set of
objects, at least not for Wicket models.

Or am I still missing something?

Re: [Wicket-user] How to best deffend models and entity classes

2007-06-25 Thread Francisco Diaz Trepat - gmail


Thanks I guess I will have to agree.

Although I still think there are some good reasons to have structure like
clasesses that only hold value. Some times it's good to have a changing
state module that does not compromise final data, until last minute. I think
it's best for unitest to have models that you can fill up to test behavior
on customize data.

It is true that in a general sensce you are adding a class that only
receives setter calls from the Form trough the IModel Implementation
(PropertyModel, CompoundPropertyModel, etc), but we are talking about some
hundred bytes and microseconds of calls, assigment operations are very
light.

Well (in the absence of further information), there would be no purpose.
But there's no need to have these extra objects in the first place.  If
your
services are written in Java, just use the pojo BOs (or DTOs) returned by
these services as your model.  If your services are written in some other
language (C++) and return xml-serialised versions of BOs/DTOs, then just
use
the xml as the model (as Igor explained).  No need for another set of
objects, at least not for Wicket models.

Or am I still missing something?

[Wicket-user] Xml output with extra lines after removeNodeChild

2007-06-25 Thread Francisco Diaz Trepat - gmail


Hi guys, sorry to be asking this here. But I'm having trouble googling this
out.

Here is the problem. Given an xml document. I read it on my app and
manipulate it, then save it when I am done.


When I remove a child, the output files shows all the extra lines from the
formatting and indent. So it looks like a big hole in the xml file after the
node is removed. Here is an example

bookshelf
   books
   book
   isbn3349583080580584308/isbn
   authorJon Stewart/author
   /book
book
   isbn9900909770543356488/isbn
   authorStephen Colbert/author
   /book
  /books
/bookshelf


Node parentNode = jonStewartNode.getParentNode();
parentNode.removeChild (jonStewartNode);

The result of this is the following xml.


bookshelf
   books




book
   isbn9900909770543356488 /isbn
   authorStephen Colbert/author
   /book
  /books
/bookshelf


How can I output the xml without this extra lines?


Thanks in advance,
f(t)
PS: here is the initialization, and configuration of the TransformerFactory,
and Transformer, and finally the save method.
/**

   this.transformer = this.transformerFactory.newTransformer();
   //setup transformer
   this.transformer.setOutputProperty(OutputKeys.METHOD, xml);
   this.transformer.setOutputProperty(OutputKeys.INDENT, yes);
   
//this.transformer.setOutputProperty({http://xml.apache.org/xslt}indent-amount
http://xml.apache.org/xslt%7Dindent-amount, 4);
   }catch(TransformerConfigurationException tcex){
   this.logger.logException(this, 
errors.storage.xml.configuringXmlTransformer, true, tcex);
   }

   }

Re: [Wicket-user] Unit testing - updating a DropDownChoice with Ajax

 FormTester formTester = 
 this.tester.newFormTester(articleEditorForm, false);
 formTester.select(rscTypesList, 0);
 this.tester.executeAjaxEvent(articleEditorForm:rscTypesList, 
 onchange);

Can you please try with:

formTester.submit();

instead of:

this.tester.executeAjaxEvent(articleEditorForm:rscTypesList, 
onchange);

To see if it's not the ajax behavior that causes problems?

You may want to have a look at an existing working unit test for
selecting a new value with the DropDownChoice:

2007-06-25 Thread Nathan Hamblen

Ryan Sonnek wrote:

Oh I hope not, I was just about to link to your post and say nice things!

 In my opinion, database access should be abstracted away from the UI
 layer altogether, which leaves the goals of databinder
 questionable.  Does anyone remember the horror of the JSP tags that
 directly connected to datbases??  Spring integration is a much more
 desirable location for database access, and there  is already
 excellent spring integration with wicket.

The way that a Databinder application works has little in common with 
any JSP horror; as in all Wicket applications the page templates contain 
no executable code and refer only to user interface components.

The coupling to the database in page templates, such as it is, is in the 
wicket:id of those components. But that is a Wicket innovation, the 
CompoundPropertyModel handling the common base case of components 
referring to property names of bound objects (and so table columns). 
You'll see (and must have seen) the same coupling in Wicket applications 
that use Spring or anything else, because it saves a ton of time and 
redundant code. And as much as you want to or need to, you can manually 
bind components to any object and field in any Wicket application, 
including one that uses Databinder.

Where Databinder is unconventional is not in the templates or anything 
that might relate to the JSP dead horse; it is that the view components 
themselves encourage the direct use of Hibernate. This also saves a ton 
of code and time, but it violates the widespread belief that grown-up 
Java applications must have hand-coded database layers. For me, 
Hibernate itself is the only layer I require between most UI components 
and the database. And I'm not about to encourage users to do extra work 
(that I wouldn't do) just to fit a traditional Java architecture 
diagram. (Elsewhere, writing ActiveRecord db code in Rails's uninspired 
view controllers seems pretty desirable to people.)

But there's plenty of room to disagree on that point, and I realize my 
position is still very much the minority in Java circles. I just thought 
I should explain it in response. (No further debate from this corner.)

As for the validation configurator, I'm trilled to have it at my 
disposal! Yes it's something I thought about doing inside Databinder 
(the list is very long, and items are rarely crossed off), but it makes 
no differences to me if things are inside or outside, as long as they 
work well. Expect it to see some action in the Databinder examples. 
(Whenever I wrap up the next version, which Wicket 1.3's trials and 
travails have allowed me to procrastinate doing for far too long.)

And thank you for contributing to the world of Wicket programming.

there are a couple of ways. override datatable.newrowitem() and do

newrowitem(..) { return super.newrowitem(..).add(new

Making sure that releases of it go into the central Maven repository is 
the only thing I can think of. I'm not sure if there are any 
wicket-stuff projects deployed there yet (there's nothing under 
org.wicketstuff), but it would be appropriate for those that reach any 
kind of finished state. The central is more reliable than 
wicketstuff.org (sorry!) and has mirrors.

[Wicket-user] Re-using page's look and feel

Hello everyone,

We are currently helping a client with establishing web application 
development. We are considering several variants and right now we are 
looking at Wicket. I have a couple of questions. I'll really appreciate 
your feedback.

We want to create a base page that other pages would inherit. This page 
would provide a unified look and feel. It would contain a header 
navigation and a bread cumb on top, a navigation pane on the left and the 
main content panel on the righ. The content of most of those items is 
going to be dynamic. As an example, selecting Actions on the top nav 
menu bar would show Actions page with its own set of commands on the 
left nav pane.

The question is, what components are the best to serve as containers for 
dymanic content? Initially (and naturally) I thought that that would be 
Panel, but apprettly it required ID-ing all the content in the markup 
which doesn't fit the requirement for dynamic content.

Regards,

Slava Imeshev

[Wicket-user] Automatic repaint of component?

2007-06-25 Thread Thies Edeling

Hi,

Say I have panel A and panel B each basing their output on the same 
model. When panel B updates the model through an ajax request, is it 
possible to have panel A refresh automatically without explicitly adding 
it to an AjaxRequestTarget ?

gr,

Re: [Wicket-user] Unit testing - updating a DropDownChoice with Ajax

* Jean-Baptiste Quenot:

  FormTester formTester = 
  this.tester.newFormTester(articleEditorForm, false);
  formTester.select(rscTypesList, 0);
  this.tester.executeAjaxEvent(articleEditorForm:rscTypesList,

 Can you please try with:
 
 formTester.submit();
 
 instead of:
 
 this.tester.executeAjaxEvent(articleEditorForm:rscTypesList, 
 onchange);
 
 To see if it's not the ajax behavior that causes problems?

Indeed  WicketTester was  overwriting field  values in  two places
when submitting via  Ajax.  I just fixed this, you  can safely use
executeAjaxEvent() now.

The related JIRA issue is:

Re: [Wicket-user] A trivial problem with tables that i can't manage

2007-06-25 Thread Landry Soules

Thank you so much for your answer.
GridView seems to achieve exactly what i need.
A problem remains, however : i don't know how to implement 
IDataProvider.iterator(int first, int count).
Must be something like this in oracle : select * from mytable where 
rownum=first and rownum count 
But how to do this in mysql ? (row_id could do the thing, but it is only 
available when your primary key is integer).
Thanks for your help.

Re: [Wicket-user] Unit testing - updating a DropDownChoice with Ajax

* Timo Rantalaiho:

 (It's a pity that WicketTester has so many bugs or shortcomings;
 if I  ever find the spare  moment I'll try to  understand how it
 works  to  be able  to  do  better bug  reports  on  it or  even
 patches. Any help for getting into it is welcome!)

Hi Timo,

It's a pity  that you didn't mention the JIRA  issue in this email
thread, as it would have helped to address the problem in a timely
manner, I was not sure what bug you were exactly talking about and
didn't ask.  Anyway now it's fixed, I discovered it is WICKET-254.

If you  are aware  of other  bugs in  WicketTester, please  let us
know, there  is no reason  why we  would want to  let WicketTester
unmaintained, I'm sorry if you feel so.  This is a great tool that
we  use  a  lot,  we  just  have  different  usecases  than  yours
obviously, or it also happens that when something doesn't work, we
don't always have the  time to fix it and work  around it like any
developer would do.

Be sure  that your bug reports  are very valuable, it's  true that
you opened the issue  a few months ago, but one  day or another we
always end up resolving it.  Don't hesitate to remind us from time
to time of  the little cracks that  went in, and keep  up the good
bug reports ;-)

If you are using an ORM tool (JPA, Hibernate, JDO) the tool might do
specific optimizations for you. But I think what most people (/

record needed.

In Hibernate, and more widely in JPA, you use

   setFirstResult()
   setMaxResults()

on your query.

[Wicket-user] Classcastexception and getSession

2007-06-25 Thread Flemming Boller


Hi

I have been troubled with a problem that is very strange. Finally I solved
it, but I am unsure whether I am doing something wrong.

I have a custom session implementation MySesission extends WebSession.

On my first page I have a popuplink opening a normal popup-page. In that
popuppage I classcast the (MySession)getSession(), but here the fun begins.

If I open the popup like this

public void onClick() {
getRequestCycle().setResponsePage(new ChooseProductPage()); // it
works like a charm
}

but if I  do it like this
public void onClick() {
getRequestCycle().setResponsePage(ChooseProductPage.class);
}

I get a classcastexception in the line with the (MySession)getSession()

Is this something I should make a jira of or am I missing something :-)

As far as I can tell from the stack trace it seems to me that there might be
a classloading problem.
Btw I am running wicket 1.2.6, java 1.5  and OSX

Re: [Wicket-user] Re-using page's look and feel

Eelco,

Thank you, but I don't think this is what I need. Those examples use 
static content panels, in a sense that IDs of the components are known, 
while I am looking for dymanic content. I will give an example Using 
pseudocode:

Container c = super.getMainContentPane();

if (groupIsPresent) {
  c.add(new MyLabel(Section Header));
  c.add(getGroupList());
else {
  c.add(new MyCreateGroupLink());
}

  MyPage() {
  getHeaderComponent().doSomehting();
  getLeftNavigationPane().add(new MyPageNavigationBar());
  getMainContentPane().add(new MyPageMainContent());
   }
 }

You would indeed use panels for that. See for instance the template
example in wicket-examples.

Hello everyone,

We are currently helping a client with establishing web application
development. We are considering several variants and right now we are
looking at Wicket. I have a couple of questions. I'll really appreciate your
feedback.

We want to create a base page that other pages would inherit. This page
would provide a unified look and feel. It would contain a header navigation
and a bread cumb on top, a navigation pane on the left and the main content
panel on the righ. The content of most of those items is going to be
dynamic. As an example, selecting Actions on the top nav menu bar would
show Actions page with its own set of commands on the left nav pane.

The question is, what components are the best to serve as containers for
dymanic content? Initially (and naturally) I thought that that would be
Panel, but apprettly it required ID-ing all the content in the markup which
doesn't fit the requirement for dynamic content.

Slava Imeshev

Re: [Wicket-user] Automatic repaint of component?


you can build a model that has listeners and a notify() method when
setobject() is called. then inside the listener you can do

{ if (getRequestCycle().getRequestTarget() instanceof AjaxRequestTarget) {
AjaxRequestTarget t=...; t.add(panela); }

Hi,

Say I have panel A and panel B each basing their output on the same
model. When panel B updates the model through an ajax request, is it
possible to have panel A refresh automatically without explicitly adding
it to an AjaxRequestTarget ?

Re: [Wicket-user] Re-using page's look and feel



Thank you, but I don't think this is what I need. Those examples use
static content panels, in a sense that IDs of the components are known,
while I am looking for dymanic content.




You have to know ids and elements they couple to up-front - the markup is
leading and components work on particular markup. But there are no limits on
what you can do with it. Can be as dynamic as you want, but you just have to
translate your needs to what Wicket expects.


I will give an example Using pseudocode:


Container c = super.getMainContentPane();

if (groupIsPresent) {
  c.add(new MyLabel(Section Header));
  c.add(getGroupList());
else {
  c.add(new MyCreateGroupLink());
}



if (groupIsPresent) {
 add(new DisplayGroupPanel(header);
} else {
 add(new CreateGroupLinkPanel(header);
}

class DisplayGroupPanel extends Panel {
 public DisplayGroupPanel(String id) {
   super(id);
   add(new MyLabel(section);
   add(new GroupList(list);
 }
}

Like that. Play around with it a bit yourself, I'm sure you'll be able to
figure something out :)

Re: [Wicket-user] Classcastexception and getSession

 I have been troubled with a problem that is very strange. Finally I solved
 it, but I am unsure whether I am doing something wrong.

 I have a custom session implementation MySesission extends WebSession.

 On my first page I have a popuplink opening a normal popup-page. In that
 popuppage I classcast the (MySession)getSession(), but here the fun begins.

 If I open the popup like this

 public void onClick() {
  getRequestCycle().setResponsePage(new
 ChooseProductPage()); // it works like a charm
 }

 but if I  do it like this
 public void onClick() {
  getRequestCycle().setResponsePage(ChooseProductPage.class
 );
 }

 I get a classcastexception in the line with the (MySession)getSession()

 Is this something I should make a jira of or am I missing something :-)

  As far as I can tell from the stack trace it seems to me that there might
 be a classloading problem.
 Btw I am running wicket 1.2.6, java 1.5  and OSX

Interesting. So what session object does it return? Did you check
whether you have duplicates in your class path?

[Wicket-user] WicketFilter NPE if filter-mapping is servlet-name rather than url-mapping

2007-06-25 Thread James Renfro

Hi All,
I'm working in 1.3.0 snapshot. Two or three weeks ago it used to be 
possible to use a filter-mapping like this one:

filter-mapping
filter-namemy.wicket.filter/filter-name
servlet-namemy.servlet/servlet-name
/filter-mapping

But it looks like a recent change to getFilterPath now forces you to use 
url-mapping instead. This was encouraged before in all the 
documentation, but not explicitly enforced. The exception I'm seeing is 
at line 467 in WicketFilter.

I know it may seem pointless to have a servlet consumer at the end of 
the wicket filter chain, but not allowing us to do it feels like an 
unnecessary limitation, and given the codebase I'm working within 
(Sakai) -- my initial guess is that it's going to represent a serious 
hurdle to making use of Wicket.

So I guess I'm wondering if there's any chance getFilterPath could be 
massaged to allow servlet-name as well?

Thanks,
James.

[Wicket-user] Interrupt page constructor and redirect to another page

2007-06-25 Thread Tauren Mills

Hi everyone,

I have a page constructor that adds several components.  However,
those components are reliant on the existence of an object in the
session.  I'd like to test if that object is null, and if it is,
redirect the user to a different page where they can make a selection
that adds a valid object to the session.

When I wrap a test around my constructor code, the page doesn't render
if the object in the session is null because it isn't finding the
components on the page:

WicketMessage: Unable to find component with id 'stateName' ...

Here is a simplified version of the code:

public RequiresStatePage() {
  super();
  if (((MySession)getSession()).getState() == null) {
setResponsePage(SetStatePage.class);
  } else {
add(new Label(stateName,((MySession)getSession()).getState().getName()));
...
  }
}

What is the proper way to do this?

Thanks,
Tauren

instead of setResponsePage(SetStatePage.class) do throw new
RestartResponseException(SetStatePage.class)

Re: [Wicket-user] Interrupt page constructor and redirect to another page

 RestartResponseException(SetStatePage.class)

That's the workaround for Wicket 1.2. Note that in Wicket 1.3 you
should be able to set the response page in the constructor. Also note
that this might not actually be better; not having to use the
exception imho looks better, but the advantage of using the exception
is that the rest of the page you have that statement in won't be build
up (and since you are not rendering it, why would you want to do that
anyway?).

if you do call setResponsePage() from another page's constructor do you end
up with both of them in the pagemap? With the exception you will only end up
with one, not sure about the other way around. if you do end up with both we
should prob fix that somehow as the other page is not reachable?
