Re Wicket Web Beans
Hi Would like to know if some one has used Wicket Web Beans in their wicket projects? One of our requirements is to add fields at runtime and be able to render it on the front end. So in this case , I have no control of building the panels for some fields that are 'yet' to be created and to infer what UI component(textfield, drop downs, radio box) should be rendered when I try to view those fields on the front end. Also will I be able to add validation rules to these fields at the same time the field is defined? I am using Wicket as the primary framework for the web layer and hibernate for the backend. I am hoping that this toolkit will be helpful in addressing this requirement. If anyone of you have used this toolkit would like to hear about your experiences. I am yet to embark on this path but in the meantime welcome your thoughts.

Re: DropDownChoice does not push value into Model
James Could you please clarify this for me, I noticed is that with PropertyModel usage in the above context. I have to define one(PropertyModel instance) for each of the form component explicitly, like so 1. ModelStudyModel studyModel = new ModelStudyModel(new StudyModel());/Top level Model In the Form: I associate the studyModel above in the constructor and ModelStudyModel pModel = (Model)getModel(); 2. firstName = new TextField(studyName,new PropertyModelStudy(pModel.getObject().getStudyName(),studyName)); // I am manually telling it to navigate to a property ..thought it will be nice if its automatic based on the expression I am unable to create a single instance like PropertyModelStudy propertyModel = new PropertyModelStudy(studyModel, study); And then use propertyModel instance for each component. Am I missing something here?

Re: Is WicketFilter.checkCharacterEncoding() safe?
As solution I can see using HttpServletRequestWrapper instead of dealing directly with the HttpServletRequest passed by the container. This way we can provide custom implementation of HttpServletRequestWrapper that overrides javax.servlet.ServletRequestWrapper.getCharacterEncoding() and if super.getCharacterEncoding() returns 'null' then use the preconfigured one in the settings and cache it. If other devs think this solution is ok then please create a ticket and we will improve it.

I ran into this issue after upgrading my Glassfish app server from 3.0.1 to 3.1-b12, containing a newer release of Weld which causes the problem to appear. After this upgrade, my log was full of warnings of the following type: WARN o.apache.catalina.connector.Request - PWC4011: Unable to set request character encoding to UTF-8 from context /xxx, because request parameters have already been read, or ServletRequest.getReader() has already been called Setting a couple of breakpoints revealed that Weld registers a ServletRequestListener and calls request.getParameter() in that listener. By specification, this listener gets called before all servlet filters, including WicketFilter, and again by specification, the invocation of servlet.request.setCharacterEncoding() from WicketFilter has no effect, since a request parameter has already been read by the WeldListener. So it there are other parts of Wicket relying on the request character encoding to be non-null, then this looks like a bug to me. Otherwise, if Wicket handles a null character encoding gracefully, then checkCharacterEncoding() is redundant, because it cannot be guaranteed to have any effect.

There's an onSubmit that you can override in Button.

The first argument to PropertyModel's constructor is the root for the property expression. If it's a model, Wicket knows to get the model's object and apply the property expression to that. What you're doing is telling Wicket to set up a property model where a String is the root and the propertyExpression is studyName. There is no studyName property on the String class, so that won't work. Also, your expression and your model type (Study) don't match here. You're telling it to traverse to the study name (which is a String I assume) and you're saying the model is of type Study. The property navigation you're trying to do won't work either. All that does is traverse the property before the method is called and passes its value in to the method as a parameter. It's not recording anything.

Re: Re Wicket Web Beans
Where does your fields come from ? In WWB, you have to provide beans, and configure them with annotations or beanprops files to control the way the beans are displayed. You can provide beans and they will be correctly displayed in a default way, with proper editing inputs according to the datatype of each field. But both the beans and the (optional) configurations need to be coded, you will not be able to provide WWB with a stream of isolated fields. Regarding validations, some are provided by WWB itself (required), anything else will be rather hard to add with standard WWB, but you can provide customized input field implementations (see customfields example). Of course those custom fields will not be used by default, you will have to configure the properties to use them.

rendering Wicket components to HTML
Hi,
First of all, before I get flamed - I've seen many topics about this since I've
been looking into this:
http://www.mail-archive.com/users@wicket.apache.org/msg27512.html
http://www.danwalmsley.com/2008/10/21/render-a-wicket-page-to-a-string-for-html-email/
http://apache-wicket.1842946.n4.nabble.com/Wicket-PDF-Page-Project-td1934168.html
My problem is that I am trying to get the rendered contents of a Page to
hopefully post process it and make a PDF out of it (using Flying Saucer) -
because of this I need to reference the currently running application for the
WicketTester (otherwise the application properties aren't available)
So, the standard WicketTester approach looks like this as far as I can tell:
public static String toString(Class? extends Page pageClass) {
final WicketTester renderer = new WicketTester((WebApplication)
Application.get());
renderer.startPage(pageClass);
String renderedSource = renderer.getServletResponse().getDocument();
return renderedSource;
}
The problem with this approach is that the init method of the application now
runs twice (once when the app starts and once when this code runs). This is
causing an error because we are mounting resources which don't like being
mounted twice.
I have tried the other approach suggested from Dan Walmsley and haven't had any
luck with this either - can anyone get this to work? Am I just making this
terribly hard on myself - is it really this complicated to render a Page to a
String? Thanks very much for any feedback you might be able to offer.

AjaxPagingNavigator give out strange error
I tried to use AjaxPagingNavigator in a simple page in Eclipse Helio with WTP (configured tomcat6). When debug, it just gives out a raw API page of ExceptionErrorPage with mismatched close tag error that reference the API page. Couple of other pages in the same app are working fine. I then tried to just copy pasted the original Wicket Example PageablesPage into my WebApplication, same thing. I commented out the AjaxPagingNavigator object, everything works fine. I step through the entire page, all components on PageablesPage are fine. The first Exception thrown is at Component class render : [code] org.apache.wicket.markup.MarkupException: Tag 'DT' (line 103, column 1) has a mismatched close tag at '/DL' (line 104, column 1) [markup = jar:file:/H:/DOCUMENTS/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/hfweb/WEB-INF/lib/wicket-1.4.10-javadoc.jar!/org/apache/wicket/ajax/markup/html/navigation/paging/AjaxPagingNavigator.ht [/code] Which is already referring to the AjaxPagingNavigator API page (I have the wicket Javadoc package from Maven in the env.)

Re: Custom AJAX component...
I have seen that wiquery for instance takes another approach in for instance
their AutoCompleteBehavior.
In that class they override respond() and get the response from the
requestcycle and start writing to it, like this:
@Override
protected void respond(AjaxRequestTarget target) {
// response: outputing the list of results as a js map
ListAutocompleteValueT, E results = autocomplete();
Response response =
this.getComponent().getRequestCycle().getResponse();
response.write({);
for (AutocompleteValueT, E autocompleteValue : results) {
autocompleteValue.write(response);
}
response.write(});
}
If this is the correct approach it would be nice because it would allow me
to have complete control over generating the response. But, is this a valid
approach? Will it not interfere with the default response? Or is everything
ok as along as no components are added to the request target?
Can anyone comment on the validity of this approach? If this is not a
recommended approach then what is the correct approach to take for getting
complete control over the response content from an ajax behavior?
Cheers
Erik
Re: Custom AJAX component...
I have been looking around a bit more and it seems like Wicket in Action provides a solution on p.260 (the book keeps on growing on me). It looks like the idea is to extend AbstractAjaxBehavior and use RequestCycle.get().setRequestTarget(new StringRequestTarget(myString)); or more generically use ResourceStreamRequestTarget. From the looks of it, the wicket-specific ajax library comes in through AbstractDefautAjaxBehavior. It beats me why some libraries are still extending AbstractDefaultAjaxBehavior if they are integrating a custom framework. Cheers Erik
How to render Enum values as RadioGroup and set default value
I have an User class with a gender field using a Gender-Enum:
public class User implements DomainObjectLong {
...
private Gender gender;
I want to bind this gender field to a radiogroup (representing all enum
values) in a registration form.
This is what I did so far:
code
public enum Gender {
MALE, FEMALE
};
public class RegistrationEntryPanel extends Panel {
private User user = new User();
public RegistrationEntryPanel(String id) {
super(id);
// default value
user.setGender(Gender.MALE);
CompoundPropertyModel userModel = new CompoundPropertyModel(user);
final RadioGroupGender genderGroup = new RadioGroupGender(
genderGroup, userModel.bind(gender));
Form form = new Form(form, userModel) {
@Override
protected void onSubmit() {
System.out.println(USER: + user);
}
};
add(form);
form.add(genderGroup);
// gender
Gender[] genderValues = Gender.values();
ListGender genders = Arrays.asList(genderValues);
ListViewGender genderList = new ListViewGender(genderList,
genders) {
@Override
protected void populateItem(ListItemGender item) {
item.add(new RadioGender(radio, item.getModel()));
item.add(new Label(label, getString(item.getModelObject()
.toString(;
}
};
genderGroup.add(genderList);
}
}
/code
This works so far: I can select a radio button and the value in the user
object is changed on submit.
But as I have to use different models for the group and the listview,
the default setting with user.setGender has no effect.
How can I preselect the first radio button of the listview or better the
dedicated MALE radio button?

Re: Re Wicket Web Beans
Hi Daniel Thank you for getting back so quickly. I used Hibernate that maps to entities in the table. Fields are defined by an administrator when he creates a new entity like Study(Hibernate entity for Study). There is a standard table called Study however if the administrator feels this new study he is creating requires additional fields he then will do the following Create Scenario: 1. Click a button to add new field 2. Provides the Field Name (either types it in or selects from a list of data dictionary fields) 3. Selects a data type from a drop down ( I have created this table with required data types so this can be sourced) 4. Enters a value for the new field. 5. Optionally, he must be able to provide the type of control this field will be linkedf to ( guess #4 and 5 are inter-related) or can WWB infer this? Not sure about this part. 6. On Save - The New field meta data is stored along with the data in another table that links to this meta data table. View/Edit Scenario: When a user reads or looks up this entity, it should bring back the general fields and the custom fields that were defined. Now, the UI should be rendered. Will I be able to use WWB in this scenario? I guess if I don't use WWB then, i have to stored field UI meta data along with values in separate tables and infer this when the UI is rendered. Will be quite a task. Thanks for your time Dan, I was planning on playing with WWB and see if my requirements can be met using WWB.

Selects a data type from a drop down ( I have created this table with required data types so this can be sourced) 4. Enters a value for the new field. 5. Optionally, he must be able to provide the type of control this field will be linkedf to ( guess #4 and 5 are inter-related) or can WWB infer this? Not sure about this part. 6. On Save - The New field meta data is stored along with the data in another table that links to this meta data table. View/Edit Scenario: When a user reads or looks up this entity, it should bring back the general fields and the custom fields that were defined. Now, the UI should be rendered. Will I be able to use WWB in this scenario? I guess if I don't use WWB then, i have to stored field UI meta data along with values in separate tables and infer this when the UI is rendered. Will be quite a task. Thanks for your time Dan, I was planning on playing with WWB and see if my requirements can be met using WWB. Reg Niv
Re: Re Wicket Web Beans
Hi Niv, I'm not sure if I just get your domain model right, the closest I think you can get is something like this: http://jweekend.com/wicketwebbeans-examples-1.1/WebBeans/?wicket:interface=:0:2::: Where you can have a list (a table) of fields, each with a name, a datatype and a value. But all values in each column will be represented with one single type of input field. Perhaps you can attempt to create a custom field for the value property, that renders a different input for each datatype, but I'm not sure if this can be done at all. One problem is, how to re-render the input if the datatype changes ? Don't think WWB allows that easily.

DynamicWebResource double request
Hello, guys Can you please advise me on the proper implementation of the DynamicWebResource subclass? When I override the abstract methods I see that my getResourceState() is called twice. The resource is registered in Wicket and is used to generate a JavaScript data.

Hi,
First of all, before I get flamed - I've seen many topics about this since
I've been looking into this:
http://www.mail-archive.com/users@wicket.apache.org/msg27512.html
http://www.danwalmsley.com/2008/10/21/render-a-wicket-page-to-a-string-for-html-email/
http://apache-wicket.1842946.n4.nabble.com/Wicket-PDF-Page-Project-td1934168.html
My problem is that I am trying to get the rendered contents of a Page to
hopefully post process it and make a PDF out of it (using Flying Saucer) -
because of this I need to reference the currently running application for the
WicketTester (otherwise the application properties aren't available)
So, the standard WicketTester approach looks like this as far as I can tell:
public static String toString(Class? extends Page pageClass) {
final WicketTester renderer = new WicketTester((WebApplication)
Application.get());
renderer.startPage(pageClass);
String renderedSource = renderer.getServletResponse().getDocument();
return renderedSource;
}
The problem with this approach is that the init method of the application now
runs twice (once when the app starts and once when this code runs). This is
causing an error because we are mounting resources which don't like being
mounted twice.
I have tried the other approach suggested from Dan Walmsley and haven't had
any luck with this either - can anyone get this to work? Am I just making
this terribly hard on myself - is it really this complicated to render a Page
to a String? Thanks very much for any feedback you might be able to offer.
Joe

Re: Custom AJAX component...
In case of wiQuery, many behaviors wicket AJAX is used (not jquery AJAX) so it seem natural to use AbstractDefaultAjaxBehavior. In other cases probably you are right and it is over killing. Is that what you are asking? Cheers, Ernesto On Mon, Aug 16, 2010 at 10:47 PM, Erik Brakkee erik.brak...@gmail.com wrote: I have been looking around a bit more and it seems like Wicket in Action provides a solution on p.260 (the book keeps on growing on me). It looks like the idea is to extend AbstractAjaxBehavior and use RequestCycle.get().setRequestTarget(new StringRequestTarget(myString)); or more generically use ResourceStreamRequestTarget. From the looks of it, the wicket-specific ajax library comes in through AbstractDefautAjaxBehavior. It beats me why some libraries are still extending AbstractDefaultAjaxBehavior if they are integrating a custom framework.
