Re: another serialization question
The value objects are not simple attributes of an entity. Let me explain what they do (a little simplified but the fundamentals are there). We have a research module that performs pricing research. ResearchItem CellPhoneResearchItem IPodResearchItem LaptopResearchItem Etc Since the identity of these research items is defined solely by their attributes they are implemented as value objects. I know this is different from your everyday value object (eg Address) Does this sound like maybe a problem that should be addressed in the domain model? Value objects were chosen since it makes it much easier in many other areas to just create a new research item, rather than call repositories to load old ones (impossible in some places). No point in loading something you know all the attributes of. The only way to get them reliably is to call ResearchItemGenerationService.generateResearchItems() -Original Message- From: James Carman Date: Wed, 11 Nov 2009 00:10:15 To: Subject: Re: another serialization question Can you go through the entity to get to these objects?

Here is the solution I used, I just emailed the list to ask if this is
the correct approach:
The following is some code which has an integer field with an associated slider
The AbstractBehavior is the bit which determines if we are in an ajax
request or not and adds the init js code in the correct place to make
sure it's called.
private void init() {
field = new TextField("field", getModel());
add(field);
WebComponent c = new WebComponent("slider");
c.setOutputMarkupId(true);
slider_id = c.getMarkupId();
add(c);
// Write out the javascript to initialize the slider
add(new AbstractBehavior() {
@Override
public void renderHead(IHeaderResponse response) {
IRequestTarget target = RequestCycle.get().getRequestTarget();
if (target instanceof AjaxRequestTarget) {
// If the target is an ajax request then we need
// to execute just the slider js.
AjaxRequestTarget t = (AjaxRequestTarget) target;
t.appendJavascript(init_slider_js());
} else {
// Otherwise render the slider when the document is ready.
response.renderJavascript(init_slider_when_doc_ready_js(), null);
}
}
});
}
private String init_slider_js() {
return "$('#" + slider_id + "').slider({min: 0, max: 1, step: 0.1});";
}
private String init_slider_when_doc_ready_js() {
return "$(document).ready(function() {" + init_slider_js() + "});";
}

Re: another serialization question
I cannot make them serializable I don't have control over them. But even if I did I couldn't because the valueobject has a reference to an entity which cannot be serializable. The project also uses db4o which would make it much harder to use a serialized version. Is dtos the best/only way?

correct way to call necessary javascript initialization when a component is added via ajax
Hi,
I'm implementing a control which consists of an integer field and a
slider where the slider comes from jquery UI.
My question is that whenever the component is refreshed via ajax, you
need to call the js initialization function.
I've done this by adding a behaviour which determines the request
target, if it's an AjaxRequestTarget it adds the init js to the target
otherwise it outputs it in the header.
Is this the correct way to do it? Is there a simpler way?
Here is the code that I've implemented as of today
public class NumberFieldWithSlider extends FormComponentPanel {
private TextField field;
private String slider_id;
public NumberFieldWithSlider(String id) {
super(id);
init();
}
public NumberFieldWithSlider(String id, IModel model) {
super(id, model);
init();
}
private void init() {
field = new TextField("field", getModel());
add(field);
WebComponent c = new WebComponent("slider");
c.setOutputMarkupId(true);
slider_id = c.getMarkupId();
add(c);
// Write out the javascript to initialize the slider
add(new AbstractBehavior() {
@Override
public void renderHead(IHeaderResponse response) {
IRequestTarget target = RequestCycle.get().getRequestTarget();
if (target instanceof AjaxRequestTarget) {
// If the target is an ajax request then we need
// to execute just the slider js.
AjaxRequestTarget t = (AjaxRequestTarget) target;
t.appendJavascript(init_slider_js());
} else {
// Otherwise render the slider when the document is ready.
response.renderJavascript(init_slider_when_doc_ready_js(), null);
}
}
});
}
private String init_slider_js() {
return "$('#" + slider_id + "').slider({min: 0, max: 1, step: 0.1});";
}
private String init_slider_when_doc_ready_js() {
return "$(document).ready(function() {" + init_slider_js() + "});";
}
}

Peter

another serialization question
One more question about serializing objects. I have a page in the application that I'm working on that calls an application service which returns a collection of objects of a type I'll call ValueObject (not serializable). ValueObject has many subclasses (which are of no concern to my wicket ui, which only deals with the ValueObject interface). So i have a page which calls the service and now has a collection of ValueObjects. What is the best way to pass this object to another page? Keep in mind it is not serializable and has no identity i can look it up by - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: getPage question
Again it's related with ajax calls. It coud solve this issue when implementing ajax polls.

Re: Proxying SSL on Apache to HTTP on Jetty + Wicket
The unique solution that i found is extends HttpsRequestCycleProcessor
to change only the protocol.
Any other ideia? Thanks All.

Re: org.apachewicket.protocol.http.WebRequestCycleProcessor
well, its either we lock on the page, or you have to make sure all
your code is threadsafe.
yes, this can be a problem for a lot of concurrent ajax requests, you
just have to make sure your responses are fast. eg if you have a
time-consuming operation do it in a background thread and make ajax
calls poll instead of block.

getPage question
In the attachment you'll see that the regions that intersect with each other indicates that the slowest method execution on stack trace. If you look at Count Delta on getPage method you will see that it equals to 37 which means thatgetPage is executed 37 times in a request. There are too many ajax calls in the web page.

Re: org.apachewicket.protocol.http.WebRequestCycleProcessor
Hi
There are parts in web which make ajax calls. In this situtation on request
blocks the piece of code till it returns a value. Do you recommend anything
about ajax calls in a web page?

HTTP Status 400 - There are some problems in the request: invalid URLPatternSpec
Hellou everyone, I use StatelessForm on GlassFish Ent Server 2.1 and I have this prob. When I submit form with method POST and Action url: http://xyz.sk/mymount/wicket:interface/:0:form::IFormSubmitListener:: server send me back status code 400 (There are some problems in the request: invalid URLPatternSpec). When I deploy same app in jetty or tomcat everything works fine. But my production enviroment is GlassFish. I think that prob is in character ":" in URL, but i dont understand because i debug that all params are decoded thrue WicketURLEncoder.PATH_INSTANCE.encode(string). Do you have some ideas ? Thanks a lot. Dave
Re: Iterate over Pages in Pagemap

Re: editing objects, backed by LoadableDetachableModels
Hi Pieter,
Ok, what I do in situations like this is to create a new transient,
serializable object (not stored in the DB) and pass it between wicket
pages as needed. With db4o, any java object can be stored at some
point by calling factory.store(object). Not sure about hibernate.
Imagine you need to configure an object using multiple screens in a
wizzard. Then just create the object, pass it from page to page in the
constructors and in the last page, store it in the db.
Rgds,
Pieter

Re: editing objects, backed by LoadableDetachableModels
This is indeed a solution, but I still think I'm doing something wrong.
Even simple properties of the Employee (like name) are reloaded from the
database for each Ajax request I do
(so, I mean: when I change first the name of the Employee and I click on the
'add Account' link, my name-change is reverted)
Isn't there a 'generic' approach for this?

Re: editing objects, backed by LoadableDetachableModels
You can keep the transient account beans in an list on your LDM, and add
then to your Employee property on every load...
LDM{
List transientAccounts;// get serialized with LDM
load(){
Employee e = service.search(id);
e.add(transientAccounts);
}
}

Re: editing objects, backed by LoadableDetachableModels
Thanks for your reply. In some situations your solution might be sufficient,
but in my situation I'm affraid not...
I cannot commit an empty Account in the db due constraint reasons. And, I
actually only want to save the Employee in the database when the user
presses the ' Save' button, not when he is adding/ modifying some Accounts.
(So, in other words, the user can always 'Cancel' his actions...

Re: editing objects, backed by LoadableDetachableModels
Hi Pieter,
I don't use Hibernate, but db4o. The principle however might help you.
I inject my factory methods into my pages using Spring (but that is a
minor detail) and when I make a change to a domain object, I always
store the object first before reloading the page (or in this case,
rendering the ajax changes). When the page reloads, it loads the
modified object from the database. This is important to also ensure
your domain objects are persisted otherwise, they might still hang
around in wicket, but might not be stored in the db.
So you need to do something like
public void onClick(AjaxRequestTarget target){
employee. addAccount(new Account());
employeeFactory.store(employee);
...
}
Rgds,
Pieter

editing objects, backed by LoadableDetachableModels
Hi,
I can't imagine that I'm the only one with the following situation.
I have a page which edits an 'Employee'. Since I use hibernate and spring I
use the LDM togeather with the OpenSessionInView.
This works great (==No more LazyLoadExceptions at all...)
But The Employee has a propertie accounts, which is a collection of
Account objects. I'm showing these objects using a Listview.
Now I want to add an Ajax link ('Add new account), which adds a fresh new
Account object. I add the containing form to the AjaxRequestTarget so the
ListView refreshes.
Unfortunately, this approach never works, since my Employee is always
reloaded from the database each reques.
(I even think the same problem shows up when you do the same without ajax..)
What is the best approach to deal with this?

Re: DataTable: Can a Cell Know of Its Row or Row Number?
Igor -
Thanks for the help. I couldn't find a getParent() on the item's class
that took a class as a parameter. However, I wrote this, and it worked:
/**
* Returns the ancestor (Wicket component hierarchy ancestor, not class
hierarchy ancestor)
* of the specified component that is an instance of the specified class
or one of its subclasses.
*/
public static Component getAncestor(Component component, Class ancestorClass) {
Component targetClassAncestor = null;
for (Component c = component.getParent(); c != null &&
targetClassAncestor == null; ) {
if (c.getClass().isAssignableFrom(ancestorClass)) {
targetClassAncestor = c;
} else {
c = c.getParent();
}
}
return targetClassAncestor;

Proxying SSL on Apache to HTTP on Jetty + Wicket
The situation here is:
https http
-> Apache ---> Jetty
Using wicket in my WicketApplication I put
private static final HttpsConfig HTTPS_CONFIG = new
HttpsConfig(HTTP_PORT, HTTPS_PORT);
@Override
protected IRequestCycleProcessor newRequestCycleProcessor() {
return new HttpsRequestCycleProcessor(HTTPS_CONFIG);
}
And in my LoginPage.java i have @RequireHttps
When i try to run the system with this config i get a error because
Wicket assumes the HTTPS control and try to change the URL (port and
replace http to https)
How i say to wicket to just change the protocol to HTTPS? And don't
change the port?
Thanks

No - it's not true. AJAX is simpler in Wicket than I've seen in ANY other application framework. You just have to know how to use it. It's also very easy to do custom AJAX things in Wicket. -- Jeremy Thomerson http://www.wickettraining.com

Thanks All. Igor - I'm a Wicket newbie. When I get more experience I'll see if I can do something along the lines you suggest. For now I just wished to know if it would be possible / sensible.

Re: Newbie: add spring to wicket quickstart
You are getting this exception from a unittest. When you use WicketTester in
combination with Spring injection, you have to tweak it a bit:
You have to add the spring applicationContext to the mock ServletContext:
Soe here a expect that you already did construct the spring
applicationContext. Creating the WicketTester:
tester = new WicketTester(createWebApplication()) {
@Override
public ServletContext newServletContext(String path) {
MockServletContext servletContext = (MockServletContext)
super.newServletContext(path);
servletContext.setAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE,
applicationContext);
return servletContext;
}
};
tester.getWicketSession().setLocale(getLocale());
new SpringComponentInjector(tester.getApplication(),
applicationContext);
testerHolder = tester;
That should do it:

Newbie: add spring to wicket quickstart
Hello.
I just created wicket quickstart project via maven and want add Spring DI to
Wicket. So I added to WicketApplication:
@Override
protected void init()
{
super.init();
addComponentInstantiationListener(new
SpringComponentInjector(this));
}
In web.xml I added:
contextConfigLocation
/WEB-INF/applicationContext.xml
wicket.jobmd
org.apache.wicket.protocol.http.WicketFilter
applicationFactoryClassName
org.apache.wicket.spring.SpringWebApplicationFactory
applicationBean
wicketApplication
org.springframework.web.context.ContextLoaderListener
In pom.xml:
org.apache.wicket
wicket-spring
${wicket.version}
org.springframework
spring
2.5.6
In applicationContext.xml:
Then when I build project in latest stable NetBeans I get this error in
console:
Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 1.579 sec
<<< FAILURE!

column in listview that is combination of two fields
I have a ListView with a requirement that I display one one the column as
combination of two fields eg. my cnameID should be cname:id.
Is there a way to get the model so that it is Label is combination of two
fields or do I have to create a wrapper object for this purpose.
ListView = new ListView("test", testList) {
@Override
protected void populateItem(ListItem item) {
TestObject testObj = (TestObj) item.getModelObject();
item.add(new Label("Name", new PropertyModel(testObj, "name")));

item.add(new Label("cnameID", new PropertyModel(testObj, "cname")));
public class TestObj{

Transaction error dont reach onRuntimeException(Page page, RuntimeException e) method
Hi all, I am testing transactionability in a site which I am developing. I got to roll back the app in case of a Hibernate DataException, but I couldnt reach my custom request cycle method onRutimeException @Override public Page onRuntimeException(Page page, RuntimeException e) Why is this? The roll back is done in endRequestCycle, while I had instructed a new model to be shown in the original page in case of succeded. It shows the succeded page instead the error one.

Both of the suggestions I think requires me to modify the logic of the
controls (either to keep track of which ones need to be updated or by
placing the rendering logic in onBeforeRender()). I think this is a
lot of work for something relative straight forward and also any
changes to permission structures and I have to modify controls.
Is there no way that I can mark a page obtained via getPage() as
requiring re-rendering? I tried getPage().dirty() before the
setResponsePage() but that didn't do anything.
Thanks for the feedback though.

Re: Mapping an association with Models
Hi,
Sorry, posted the previous one by error, this is what's missing in the code:
class APanel extends Panel(){
private List selectedBs;
public APanel(){
A a = getA();
List choices = getBChoices();
cbmc = new CheckBoxMultipleChoice("id", choices);
cbmc.setModel(new PropertyModel(this, selectedBs));
Form f = new Form("form"){
onSubmit(){
List abs = a.getAB();
abs.removeAll();
for (B b : selectedBs){
AB ab = new AB(a, b);
abs.add(ab);
}
// a contains properly initialized ab elements
}
}
f.add(cbmc);
}
Question is, does 'selectedBs' get serialized in pageMaps ? If so, I suppose
it would be better to store only selectedB's id's...
Thanks, and sorry again for the double-posting inconvenience !

a1, a2, b1, b2). Let's suppose I have a Form for editing A objects, in which
the user can choose many B values by means of a CheckBoxMultipleChoice cbmc,
with model object and choice list of type List.
In the form's submit method, I create as many as necessary AB objects,
combining selected B's id's with current A's id.
class APanel extends Panel(){
private List selectedBs;
public APanel(){
}
Re: Force page reload/re-render
Hi Pieter,
Components that have .setVisible(false) will never be evaluated again
automatically. You need to call .setVisible(true) on all that apply.
One way would be control visibility in the base panel by overriding
onBeforeRender() to handle all the cases in one place. e.g.
class ControlPanel extends Panel {
protected void onBeforeRender () {
Role role = getModelObject();
caseOnePanel.setVisible(false);
caseTwoPanel.setVisible (false);
if (role instanceof CaseOne) {
caseOnePanel.setVisible (true);
}
else if (role instanceof CaseTwo) {
caseTwoPanel.setVisible (true);
}
}
}
Or you could override .isVisible() in your sub panels to control when
they are visible.
I like the on before render way myself because there is no performance
penalty if the visibility logic is complex (Component.isVisible() is
called alot during the rendering phase).
Regards,
Mike
To recap, I have a control panel visible on each and every page and in
that control panel, you can select the appropriate role you want to
use. Based on that role some menu items will be visible or not
(example below is correct). I am sure this problem has been solved
before :-0 as this is a very normal usecase for context sensitive
navigation.
It seems that there is no way to force the page to re-render using getPage()?
Thanks for the feedback so far. I keep on coming up against this issue
and have not found a reasonable solution to the problem. The
javascript option seems to be best so far.

Re: Force page reload/re-render
Hi Pieter
Due to the Java-Nature of Wicket, things done in the constructor are
only executed once for this instance. Since F5 only re-renders the
instance, the expression setVisible(whatever()) is only executed once.
The most dynamic implementation would be to override isVisible() for
every component that changes its visibility dynamically or if that would
lead to lots of code duplication, you could write a behaviour doing
exactly that and add it to every component (or container) as needed.
isVisible() is evaluated during each and every rendering phase, meaning
upon every F5 reload as well.
This is the way we do it for dynamic content.

Hi Pedro,
I tried setResponsePage(getPage()) but the problem is it does not

setResponsePage(getPage().getClass()) only works for stateless pages
and on most of my pages, I pass params via the constructor.
The javascript option will be a last resort, but it seems to be not

No, I'm not planning to visit London any time soon : for a start I'll need
to ask for a visa... and besides that I'm a family man and I have to take
care of my wife and children during weekends:-)

AW: Iterate over Pages in Pagemap
I agree that i should be carefully.
But, back to the timer, let's assume I have 16 versions of one page in pagemap
and each of 16 versions has a timer.
Then there are 16 timers polling information from server, well if there are
only 16 versions of one page, the traffic is low, but if the page count
increase I have much unneeded traffic.
You know I mean?
I will look at push but I hold timer in mind.
Btw, do you come to London on 21.11 (Jweekend)?

Re: Iterate over Pages in Pagemap
I haven't used wicketstuff-push myself so I can't be of much help there. I
once had to implement some push functionality and I used DWR in combination
with Wicket. Going the reverse AJAX can complicate things a lot (or so I
believe). Thus, think carefully if what you want to achieve cannot be

from time to time and if new navigation is available updates what you need

Well, no. The session holds the navigation and triggers a method on it, so the
navigation rebuilds itself.
I need to hold it in session cause the available navigationentries depend on
user roles.
But your right with reverse ajax, I think I need it.
Wicket is so "Swing", so I totally forgot I'm working with a webapp :)
I will read more about reverse ajax.

Just one question? How would a remote page "know" that it has to reload
itself? Do you plan to do that next time user get backs to the server with
an AJAX request? If so, then you don't need anything else (I guess.) But if
you want this to happen even if the user do not interact with the page. Then
either you need a timer or use reverse AJAX.

Just google for reverse AJAX, comet, server push, etc and you will have

AW: Iterate over Pages in Pagemap
Well, i don't want a timer in the page. This causes unneeded checks.
That's why I thought of the simplest solution.
The basepage gets its navigation from session (which gets rebuild upon changes
to stay up2date).
Now I need a way to notify the page that navigation changed.
So I implemented following method in basepage.
...
public void refreshNavigation() {
this.navigation.replaceWith(AuthenticatedWebSession.get().getNavi());
AjaxRequestTarget.get().addComponent(this.navigation);
}
...
Now all I have to do is call this method for each active page to refresh
navigation (or am I wrong?).
Can you tell me a bit more about reverse ajax?

Re: Combination CompoundPropertyModel and ChoiceRenderer on DropDownChoice gives problems
Hi Alex,
Expose description and id on your model's object.
>
If I understand what you're saying, this was the problem, we did want the
Component's Model to be i.e. a String, while giving the choices an
id-descr-like bean... But this is not working (must have same object type on
choices and component model), so the code above returns a List of Strings as
choices, and uses a suitable choiceRenderer in order to retrieve
descriptions from the 'description-enhanced' choice model, which consists of
a Map ...
public final static ChoiceRenderer listRenderer = new
> ChoiceRenderer("description", "id");
>
If i'm not wrong, this one will work when there is no Model object but when
there is one, it will throw out an exception, complaining it doesn't find
property 'id' nor 'description' in class String (which will be the class of
the Component's Model object)..
I don't know If i got your point though,
Thanks!
