Re: Wicket database access
Wicket will not force any method or framework down your throat, wicket is a web framework. It's completely up to yourself to decide which way you want to go.. Its probably why you get so differentiated answers.

Re: Wicket database access
Hi wjser, I'm frustrated, because i didn't any answer to my question. I searched the wicket documentation and the web, but found no information. since Wicket is a Web-Application-Framework many believe, that it should focus on especially that area. Wicket provides very good tools to do data manipulation and allows you to choose whichever Framework you want to use for Database-Access. Have a look at http://databinder.net/site/show/overview or just write your own jdbc-Backend. Nowadays no serios web application can be developed without database access and a no developer should be forced to use an object-relational mapper. Please explain what you mean here.

Re: How to make a Form work both Ajax and no Ajax?
You could use an AjaxFallbackButton on your form, eg:
AjaxFallbackButton a = new AjaxFallbackButton(id, form)
{
@Override
protected void onSubmit(AjaxRequestTarget target, Form
form)
{
//normal stuff
if(target != null)
{
//ajax stuff
}
}
};
form.add(a);
which should work with and without ajax.

Re: Accessing prototype scoped panel beans using @SpringBean annotation
Hi Tom,
I'd suggest not to use Spring to manage panels. You should rather create a
new panel for every page and request. You should use Spring to manage your
services and inject those into your panels.

Hi,
First of all let me apologise for the length of this post, I thought I
should include too much info rather than too little.
I'm using wicket-1.3.1, Spring 2.5.1 on JDK1.5 and Jetty6.1.6. My goal is
to define 1..n Panels in my Spring application context then access them
from within a test page using @SpringBean annotations.
applicationContext.xml contains:
bean id=testPanel1 class=com.example.TestPanel scope=prototype
constructor-arg value=testPanelOne/
/bean
TestPage class is as follows:
public class TestPage extends WebPage {
@SpringBean(name=testPanel1)
private TestPanel testPanel1;
public TestPage() {
add(testPanel1);
}
}
And TestPanel class is as follows:
public class TestPanel extends Panel implements ITestPanel {
private TestForm form;
public TestPanel(String id) {
super(id);
form = new TestForm(testForm);
form.setTestFormField(oranges);
add(form);
}
private class TestForm extends Form {
private String testFormField;
public TestForm(String id) {
super(id);
add(new TextField(testFormField, new PropertyModel(this,
testFormField)));
}
protected void onSubmit() {
PageParameters params = new PageParameters();
params.add(testFormField, testFormField);
}
public void setTestFormField(String testFormField) {
this.testFormField = testFormField;
}
}
}
So, the problem is that when I hit http://localhost:8080/ the
add(testPanel1); line in the constructor for TestPage causes the
following exception to be thrown:

RE: Wicket database access
If you're looking for automatic mapping from the database to the web, you might be better off with something like Ruby on Rails. What I believe you're asking for is simply outside the scope of Wicket. That said, there is no magic in Wicket. You access a database as you would in any other Java application (i.e. do JDBC or use a ORM or whatever tickles your fancy). BTW, I am very pleased that Wicket does not adress accessing the database. We (the product I'm developing) happen to get our data from a bunch of services located somewhere outside the Webserver, so any database access architecture inside Wicket (a la Seam) would be a useless complication for us.

Re: how to create the component dynamic?
Hi Mead, I'd say that wicket is a real cool choice to accomplish this (I know what I'm talking about as I hacked such a tool in PHP years ago in my programming infancy ;) ) There is no general answer though. But for different question types you could do if (type == DROP_DOWN_QUESTION) add(new DropDownQuestionPanel(panel, question); else if (type == RADIO_QUESTION) add(new RadioQuestionPanel(panel, question); // you got the idea you could also create the panels dynamically by giving a type such as com.foo.questiontype.DropDown using reflection. This way you could create a quite flexible solution, where you could drop in just another jar to add new question types. If it comes to different numbers of possibilities, RepeatingView might be a good choice. Best regards and good luck Mead-2 wrote: Well, I wanne build a Survey-System!

On the homepage i've added the annotation: @AuthorizeInstantiation(Roles.* USER*) but when i run the application and go to the URL, it goes directly to the homepage and the loginpage isn't called. This isn't supposed to happen, because you need the user rol to get there. Does anyone have an idea about what i'm doing wrong?
Re: Wicket-auth-roles problem
A few questions: 1) does your session extend AuthenticatedWebSession 2) if so what does your getRoles() method in your web session look like 3) presumably you mean @AuthorizeInstantiation(Roles.USER) - without the stars? 4) do you manually set any of the options on getSecuritySettings() in your webapplication class (afaik you shouldn't, i don't) Richard Ted Roeloffzen-2 wrote: I've made a webapplication class that extends from AuthenticatedWebApplication in the wicket-auth-roles project version 1.3.1 I've implemented the needed methods, such as getHomePage, getSignInPageClass and getWebSessionClass.

Re: Combining Ajax and non Ajax pages
Guys - thanks for your continued help with this, but I'm still having some
problems with:
Attempt to set model object on null model of component.
I now have some code cut down to the simplest possible example (attempting
to follow the advice given already):
public class AreaChoiceModel extends LoadableDetachableModel {
protected Object load() {
return ((WholSession) Session.get()).getAreaList();
}
}
public class WholSession extends WebSession {
private IModel areaModel = new AreaChoiceModel();
public WholSession(Request request) {
super(request);
}
protected void onDetach() {
areaModel = null;
}
public IModel getAreaModel() {
return areaModel;
}
public ListArea getAreaList() {
return ((WholApplication) getApplication()).getAreas();
}
}
public class PanelSearch extends FormComponentPanel {
public PanelSearch(String id) {
super(id, ((WholSession) Session.get()).getAreaModel());
add(new SearchForm(searchForm));
add(new FeedbackPanel(feedback));
}
private class SearchForm extends Form {
public SearchForm(String id) {
super(id);
DropDownChoice areas = new DropDownChoice(areas,
((WholSession)
Session.get()).getAreaModel(), new
ChoiceRenderer(name, id));
areas.setOutputMarkupId(true);
add(areas);
}
protected void onSubmit() {
System.out.println(onSubmit called);
};
}
}
Page with panel and form loads OK with selection box populated with my top
level Area list (I've removed everything else).
Clicking the button results in the error:
WicketMessage: Method onFormSubmitted of interface
org.apache.wicket.markup.html.form.IFormSubmitListener targeted at component
[MarkupContainer [Component id = searchForm, page =
sds.whol.wicket.pages.Index, path =
0:panelSearch:searchForm.PanelSearch$SearchForm, isVisible = true,
isVersioned = false]] threw an exception
Root cause:
java.lang.IllegalStateException: Attempt to set model object on null model
of component: panelSearch:searchForm:areas
at org.apache.wicket.Component.setModelObject(Component.java:2850)
I'm obviously still missing something important here (or maybe I've cut out
too much code :-}). I suspect it's something very simple, so any further
pointers welcome.
Note - I've now bought the Wicket In Action eBook, so may have this worked
out once I've had time to study it in some detail.
Thanks again.
Michael O'Cleirigh wrote:
Hello,
This error happens because the intermediary panel between the form and
the drop down choice does not have a model.
Changing the PanelSearch constructor to call super (id, new Model())
should fix the problem.
You might also want your form panel to extend FormComponentPanel instead
to get better validation support.
Mike
Or you did not set the model on the dropdown.

You have to do something like
private IModel model=new WhateverModel(null);
in your session.

Don't add wicket components to the session, use models.
for example

class PanelSearch extends Panel

public PanelSearch(String id)

class SomePage extends WebPage

super();
add(new PanelSearch(search));

The trick is always using the shared models in your session, that
is
why you don't need setters for them and you have to initialize
them
properly with some default.
That way the form automatically writes the new values to your
session
and you don't have to do that manually.
How much less code can you have?

OutOfMemoryError (not PermGen) in PageSavingThread
Hi all, We're getting an OutOfMemoryError (Wicket 1.3.1 on Tomcat 5.5.17 with Sun JVM 1.5.0_06-b05) in the PageSavingThread occasionally and I was just wondering if anyone had seen this before.

Re: Wicket database access
One thing you might want to consider is that Wicket's form support is very good at editing beans (stuff with getters/setters) which means you're going to have to transform data from your JDBC ResultSets into a Java objects. That sounds a lot like ORM to me and there are great frameworks out there for that. It's not that people or frameworks try to cram ORM down your throat; it's that ORM is a proven solution to a common problem. With the combination of spring/hibernate/wicket, I can whip together a form that updates a database (with validation) and a screen that shows you query results (with paging, sorting) within a half hour (maybe shorter if I don't take time to sip coffee :). What you need is a nice quickstart platform for doing spring/hibernate/wicket that gets all the gruntwork done for you up front. I think they were working on a mvn archetype for that.

Re: Accessing prototype scoped panel beans using @SpringBean annotation
Stefan Fußenegger wrote: Hi Tom, I'd suggest not to use Spring to manage panels. You should rather create a new panel for every page and request. You should use Spring to manage your services and inject those into your panels. Best regards, Stefan Hi Stephan :) (I work with Tom) We have a work around for this specific problem, and it still involves spring, but not using panels directly. Basically the situation is as follows. We have a main wicket project which is published as a jar. There are also other modules also published as plugin jars. We launch these with an embedded jetty instance. The problem is the Main project contains the page instances, and the other jars contain the panels. The Main project has no idea about which panels are available, as these will be determined at run time by whatever has been configured (thru spring). The main jar has no knowledge of which panel classes exist - so we cannot really instantiate new ones using plain old java. There are a few ways to approach this, ie, having some class loader which resolves given string class references, and those strings are wired in through spring. This works - but feels a bit hacky. Our workaround is .. somewhat similar - we basically have a panel factory in the plugin that instantiate a panel and return it. We can then wire these panel factories thru spring to a given page. This turns out to be quite elegant - however it would be nice if we had the ability to wire plugin panels to the main jar directly without this factory.

ant-based example project?
Hi all, I just downloaded Wicket 1.3.1 and now I want to use Ant for building my app and deploying it to Tomcat. I thought it would be easy to find a good example of an Ant-based project. But no. Everything seems to be all Maven... My question is: Is there a good example of an ant-based wicket project for wicket-newbies? (If someone has such a project lying around, would you consider making it available?) Many thanks! /ulf PS. I love Wicket, it's excellent! But I am afraid many potential users are probably lost simply due to its tight connection to Maven, and that is a shame... The point is: Wicket is so easy to use that it is within reach also for less experienced programmers. -- Why ruin that with Maven? (Just look at all the threads about Maven-related problems.

Problem with multiwindow app
Hi all!!! I have application with 2 pages. First page lists users names and each element of list is link to second page that shows user details. I want to have this second page shown in other tab or window. Everything works fine when I click one user link, detail page is loaded and i can operate on it. But when i click on i.e. 5 links in very short time and 5 tabs are opened i get 'page expired' on each of them. Thanks to logs I discovered that when i open page in other tab or window it renders twice. Maybe this is the problem.

Re: Accessing prototype scoped panel beans using @SpringBean annotation
What do you mean by directly? Do you want to inject the panels rather than the factories? You could probably try to write your own annotation and use a custom org.apache.wicket.injection.IFieldValueFactory Ned Collyer wrote: Stefan Fußenegger wrote: Hi Tom, I'd suggest not to use Spring to manage panels. You should rather create a new panel for every page and request. You should use Spring to manage your services and inject those into your panels. Best regards, Stefan Hi Stephan :) (I work with Tom) We have a work around for this specific problem, and it still involves spring, but not using panels directly. Basically the situation is as follows. We have a main wicket project which is published as a jar. There are also other modules also published as plugin jars. We launch these with an embedded jetty instance. The problem is the Main project contains the page instances, and the other jars contain the panels. The Main project has no idea about which panels are available, as these will be determined at run time by whatever has been configured (thru spring). The main jar has no knowledge of which panel classes exist - so we cannot really instantiate new ones using plain old java. There are a few ways to approach this, ie, having some class loader which resolves given string class references, and those strings are wired in through spring. This works - but feels a bit hacky. Our workaround is .. somewhat similar - we basically have a panel factory in the plugin that instantiate a panel and return it. We can then wire these panel factories thru spring to a given page. This turns out to be quite elegant - however it would be nice if we had the ability to wire plugin panels to the main jar directly without this factory.

Hi One thing you can check is if you have any references (instance variables, possibly implicit) to pages from your component hierarchy. That seems to cause memory leaks in the serialization.

Re: OutOfMemoryError (not PermGen) in PageSavingThread
Thanks Henrik, We don't store Page references (we use getPage()) except in one case but that's a reference to the current page. I did come across this information about a JVM bug: http://bugs.sun.com/bugdatabase/view_bug.do;jsessionid=414ae2ad0e65bfabc12f25012527?bug_id=4879883 It looks like there's a property we can try but that it's not necessarily and ideal (or even acceptable?) solution? Sun devs say this was fixed in 1.4 but people have been complaining about it in 1.5 and 1.6. Some more information on this: http://osdir.com/ml/java.bdbje.general/2005-05/msg00027.html So, we'll give it a shot and report back to the list (in case others come across this problem). Though ... it does concern me some that we would have used up 64mb of direct memory writing out pages. It appears as though the memory is deallocated using a separate thread (in java.nio.DirectByteBuffer) so it's possible that wicket is writing out pages and using up the direct memory before it can be cleaned up.

Right, I did not run JMeter for hours to find our some growing instance count. Until now I used the heapdump I've got from an OOME on our production system.

RE: usage of AbortWithHttpStatusException
If you would like to have custom Http error pages you can update the wicket

dispatcherREQUEST/dispatcher
dispatcherERROR/dispatcher
/filter-mapping
error-page

Hi,
How is AbortWithHttpStatusException meant to be used? I expected that this
exception would result in a (e.g.) 404 error page to be shown. However, all
I get is an empty page. Any ideas on how I can get a nice, custom error page
to show up?
Cheers, Stefan

Re: Wicket database access
I too am new to Wicket, and wanted to start using it without having to learn a persistance tool. I have never used a framework before, just JSP and Servlets. I tried dabbling a little with JPA, but found it confusing - especially when working with tables whose primary keys have more than one field. I use MyEclipse within Eclipse, and that helped me some. My app was mostly inquiry only into a legacy database created in SQL Server. I come from an AS400/ISeries background. We took the database from that system and converted to SQL Server. This app had a search panel, and several repeaters that took you to more detail. What I did from the JPA experience was create a java class for most of my tables and also a detachable model class for those that made sense. I have one DAO - Data Access Object - a class that would connect to DB via JDBC and using SQL populate (map from DB to) the objects. This DAO had several methods that either populated the table object with one row, or another method that would create a LIST object containing several rows. I would use these LIST objects to populate whatever Wicket repeater you wanted to use. I found it much better/faster to create a java class for just the fields that the LIST needed, and then through the selected LIST row, I would get the larger chunk of data to populate a panel. The LIST would always contain the keys I needed to get the larger chunk from the DAO. The table to object java classes (I guess you could call them beans) contained all the fields in the SQL result set that I was going to use, getters and setters, and a build method. I found placing the build method within the bean was much easier than doing it in the DAO. The DAO instantiated the object and called the build method - passing the resultset as a parameter. I hope this makes sense. It took my quite a while to get to this point, and was the most difficult part of learning Wicket. You have to play with it a bit to see exactly where you want to call your DAO and build your data objects. I do want to learn a persistance tool and integrate that since most Wicket users tend to use this practice. I am by no means good at using Wicket yet, but have a thurst to dig deeper. I just bought the Wicket In Action book and hope that this will do the trick. -- View this message in context: http://www.nabble.com/Wicket-database-access-tp15613515p15634454.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Wicket database access
while wicket has first class support for editing beans, it is by no means the only way. it is quiet trivial to create a ColumnModel that is like a property model but reads data from a resultset object and populates a prepared statement object... all im saying is that you dont have to box yourself into the bean mindset -igor On Fri, Feb 22, 2008 at 4:50 AM, James Carman [EMAIL PROTECTED] wrote: One thing you might want to consider is that Wicket's form support is very good at editing beans (stuff with getters/setters) which means you're going to have to transform data from your JDBC ResultSets into a Java objects. That sounds a lot like ORM to me and there are great frameworks out there for that. It's not that people or frameworks try to cram ORM down your throat; it's that ORM is a proven solution to a common problem. With the combination of spring/hibernate/wicket, I can whip together a form that updates a database (with validation) and a screen that shows you query results (with paging, sorting) within a half hour (maybe shorter if I don't take time to sip coffee :). What you need is a nice quickstart platform for doing spring/hibernate/wicket that gets all the gruntwork done for you up front. I think they were working on a mvn archetype for that.

Have a look at http://databinder.net/site/show/overview or just write your own jdbc-Backend. Nowadays no serios web application can be developed without database access and a no developer should be forced to use an object-relational mapper. Please explain what you mean here.

use something like this
DropDownChoice areas = new

(WholSession)Session.get()).getAreaModel(), new ChoiceRenderer(name,

where getAreaSelectionModel() is the model which contains the selected

Hello,
This error happens because the intermediary panel between the form and
the drop down choice does not have a model.
Changing the PanelSearch constructor to call super (id, new Model())
should fix the problem.
You might also want your form panel to extend FormComponentPanel instead
to get better validation support.

Or you did not set the model on the dropdown.

Then they cant be collected by gc, and dada a memory leak. Since the application will continue to produce more resources which cannot be cleaned. Now they may be very small, and things can be triggered from everywhere in the application so theres A LOT to watch out for.. This is where a profiler and jmeter can help a little, but in the end it still feels a lot like looking at tea leaf's.. But if you dissect it, with jmeter and a profiler you will find the problem in the end. BTW, as I remember it jprobe[1] has a freeversion, which is adequate..

Then the difference should be more clear. I once had an error that originated in a hashmap that locked session context, it was very hard to find and was not our error but a 3rd party I used 4 very long days for finding the problem... It's a little abstract to use a profiler as it will not give you a clear idea as everything originates in class[] int[] etc... Of course.

Re: AutoCompleteTextField user selection
Hi Michal, could you come up with some code? mf 2008/2/22, Bushby [EMAIL PROTECTED]: I have an AutoCompleteTextField which searches for a person object. When a person is selected from the auto complete, I want to update the panel and the model with the person's information. I have tried adding an AjaxFormComponentUpdatingBehavior, but it gets called twice. Once with the text entered by the user, and the second with the text from the auto complete. How do I capture just the selection event?

Howto use .xhtml instead of .html for template file extension
I follow this:
http://cwiki.apache.org/confluence/display/WICKET/Use+a+different+extension+for+template+files
added this to MyPage:
@Override
public String getMarkupType() {
return xhtml;
}
and it doesn't work. Firefox wants to download the file instead of showing
the page.
http://www.nabble.com/file/p15641885/no-go-xhtml.jpg
IE7 cannot even download the file.
What am I doing wrong?

Re: Combining Ajax and non Ajax pages
Now getting much closer - but not 100% there yet.
Code with 3 dropdowns for area / country / region now looks like below.
I don't set the model for the Panel, like:
setModel(((WholSession) Session.get()).getAreaModel());
I have 3 models - one for each dropdown - and not sure how to add them all
or combine them (or if this is possible).
I'm setting each of the models in the session. The area list is always the
big master list of top level areas, and intially the others are empty, so:
private ListArea areaList = ((WholApplication)
getApplication()).getAreas();
private ListArea countryList = Collections.EMPTY_LIST;
private ListArea regionList = Collections.EMPTY_LIST;
Then in the onchange in the AjaxFormComponentUpdatingBehavior I can do:
protected void onUpdate(AjaxRequestTarget target) {
// Reset the country dropdown when the area changes
Area area = ((AreaChoiceModel) areasDDC.getModel()).getArea();
ListArea lst = new ArrayListArea(area.getAreas());
countriesDDC.setChoices(lst);
((WholSession) Session.get()).setCountryList(lst);
countriesDDC.clearInput();
regionsDDC.clearInput();
target.addComponent(countriesDDC);
}
which is manually setting the countryDDC choices by getting the countries
from the selected Area.
This all works - selections survive page refreshes, going backwards and
forwards from the results page to the home page, etc.
But the current problems are:
1. if I select an area + country + region combo - eg, N America - USA -
Alabama and sumbit, then change to a country with no recorded regions - eg,
N America - Bermuda - the region box clears OK with
regionsDDC.clearInput();
but the region model in the session sticks as the previously stored Alabama.
Obviously, I'm not setting the region model in the session correctly, and
I'm not sure how to make this automatic - hence the bits of hard coded stuff
I've resorted to to get this far.
2. The please choose options go missing after the first time I select
things - eg, selecting N America defaults to Bermuda.
I suspect these issues can be solved if I can work out how to get multiple
models registered in the session so they update automatically like the
examples provided earlier.

private IModel areaModel = new AreaChoiceModel();

Re: Tabular form validation problem with FormTester
Hi!
Is there a bug in handling the first listView row submitted using
WicketTester/FormTester?
Regardless of the original values displayed on the first row of the
listView, the textField.getConvertedInput() and
checkbox.getConvertedInput() return null and false values at the form
validator, respectively.
If I surpass the validator, the form is submitted just fine. It is
only in the validator where the problem occurs and it is on the first
row only (i.e., elements listView:0:todo and
listView:0:description). Other rows submitted using the FormTester
seem to work just fine so far.
Is this a bug or am I using it improperly? Here is the test code; the
rest of the code remains the same as previously in the thread Tabular
form validation problem with checkboxes (all the previous advices
taken, though):
public void testThatCheckingARowButLeavingTheDescriptionEmptyResultsInError()
{
tester.startPage(Todos.class);
FormTester formTester = tester.newFormTester(Todos.TODO_FORM);
formTester.setValue(listView:3:todo, true); // I do not touch
row 0 but those items' default values are not received by the
validator
formTester.submit();
tester.assertRenderedPage(Todos.class);
String testString = new
Localizer().getString(checked_but_description_missing, new Todos());
System.out.println(testString= + testString);
tester.assertErrorMessages(new String[] { testString, } );
}

2008/2/21, Igor Vaynberg [EMAIL PROTECTED]:
this line: textRequired = (Boolean) checkBox.getModelObject(); should not work
you are inside a validator, that means models haven not been updated
yet. models are only updated once all type conversion/validation
succeeds.
inside validators you should use formcomponent.getconvertedinput() to
read the value that will be put into the model if validators succeed.

a proper solution would be to use a validator or a formvalidator to do
this. generally you never iterate over components to do validation in

Judging from the performance of the checkbox, I have a wrong plugin
point for the validator. How would you put it?
you didnt show the part of code that generates the list...
it is just a dummy list of new todo items.
they are unique but you are using a listview? so what you have is not
a list at all, it is a collection of random items.
perhaps listview is not what you want. if you keep regenerating items
every request
They are not random. Here is the code generating the items:
ListTodo linkedTodos = new LinkedListTodo();
{
Todo todo = new Todo();
todo.setDescription(Dummy);
todo.setSelected(true);
todo.setTodoDate(Convert.toDate(1.1.2008);
linkedTodos.add(todo);
}
// ... and I have repeated a number of these ... say 7 pcs
return linkedTodos;
The page uses a linkedTodos singleton in the sence that the list is
generated only the first time the page is loaded. So they are not
random.
Is there a bug with the checkbox?
doubt it
Well.. the validator fails to receive the submitted checkbox state.
Did I attach the validator improperly? Or should I read the checkbox
value in some other way? The checkbox state submitted from the browser
is not received by the validator using the code I posted before. The
textfields function properly, but the checkboxes seem to somehow be
disconnected... they sometimes change state according to the selection
in the browser window, sometimes not. Mostly not ;) Odd times? Very
strange.

There are a few ways to approach this, ie, having some class loader which

I don't know why you feel this hacky. It looks clean and easy to me:
public class TestPage extends WebPage {
@SpringBean(name = config)
private Config config;
public TestPage() {
add(PanelFactory.getPanel(config, testPanelOne));
}
}
public class PanelFactory {
public static Panel getPanel(Config config, String id) {
Class? extends Panel c =
Class.forName(config.getPanelClass()).asSubclass(Panel.class);
Constructor? extends Panel constructor =
c.getConstructor(String.class);
return constructor.newInstance(id);
}
