2nd try: stateless AJAX behaviors in stateful page without its serialization
I have pretty stateful page with plenty of AJAX components. Most of these components have behaviors, which renders JavaScript code for calling AJAX requests to Java code. Because page isn't stateless, each request causes serialization of page. So far so good. But some of these AJAX requests doesn't change page ever, so serialization of page isn't necessary. For example it is forward caching data for (home-brewed) datagrid component. These requests are calling continuously and serialization of page during each request causes delays. There are some projects for stateless wicket components out there, e.g. http://code.google.com/p/jolira-tools/, but it solves another situation -- request of stateless components are processed on new instances of stateless pages. I want to process requests on existing stateful page instance but without its serialization. I have tried to implement this in my own RequestCycleProcessor.resolve(), but I hung on searching for page from requestParameters because Session.getPage() always touches page and it causes serialization after request processing. Is there any example, idea, whatever for implementing this in Wicket?

Re: 2nd try: stateless AJAX behaviors in stateful page without its serialization
No, I want to process these requests in context of existing original page instance, but without page serialization. Standard processing of ajax requests is implemented in WebRequestCycleProcessor class, in method resolve(). This method is called with RequestParameters instance which is only parsed request parameters like page, pagemap and component identification. Standard wicket implementation of resolve() searches for page by calling Session.getPage() method -- that's ok, but calling this method calls also Session.touch() method, which causes serialization of this page after processing request... What I want is: in processing some specific requests do not serialize the page, because these requests don't change the page and they are called continuously by design. I can extend WebRequestCycleProcessor and override resolve() method, but I cannot avoid searching page by calling Session.getPage(). M.

how to handle clear input for custom FormComponents
Hi all, I've developed a custom FormComponent (by subclassing FormComponentPanel) to act as a reference from one object to another (eg a Customer to an Address), but am having problems figuring out how to handle clear input (ie, if the user hits the cancel button on the form). To explain a little further, the FormComponent is called EntityLink, and renders the reference (eg the Customer's homeAddress) a hyperlink. I have a button on the EntityLink panel allowing the user to perform a search for other objects of the correct type, and then select it. Doing this updates the EntityLink component, with a pending value (ie of the new homeAddress). If the user hits the OK button, then the pending value is copied over to the domain object (ie to the Customer's actual homeAddress property). In the cancel button's onSubmit() method I'm calling getForm().clearInput(), which seems to use a visitor to call clearInput() on all child FormComponent's. The FormComponent's clearInput() method seems only to set the rawInput to a constant (NO_RAW_INPUT), which looks like it's a magic value of some kind when the form component is actually rendered - all rather low level. I think what I'd like is to eagerly capture this clearInput so that I can reset my EntityLink's hyperlink back to the original value and discard the pending value. However, clearInput() is unfortunately marked as final so there doesn't seem to be any easy way to capture this. Looking at other implementations of FormComponentPanel (eg DateTimeField) they are really very little other than wrappers around simple FormComponents, so they don't offer any real clues. Can anyone help me here, then?

Re: DropDownList
Josh,
This seems to be one of the hardest things for new Wicketeers,
understanding how models work. Basically, when you tell the
DropDownChoice to use a model, you're saying when you want to
know/update what's selected, go here. The funny thing about models
is that they really are quite simple; it's just a mindset change.
Good luck!

Re: how to handle clear input for custom FormComponents
I found a way to make this work (though I worry the solution might be a little fragile). Basically, I'm overriding getInputAsArray() in my wrapper EntityLink, delegating to a hidden text field; then, in onBeforeRender() I check if there is input, and if not then infer that clearInput must've been called on and so zap the value of the hidden text field. If anyone cares to look at the code, it's on sourceforge: http://wicketobjects.svn.sourceforge.net/viewvc/wicketobjects/trunk/main/viewer/src/main/java/org/starobjects/wicket/viewer/components/entitylink/EntityLink.java?revision=78view=markup Thanks anyway Dan Dan Haywood consultant, mentor, developer, author agile, ddd, oo, java, .net, sybase MA, MBCS, CITP, CEng /mail: /d...@haywood-associates.co.uk mailto:d...@haywood-associates.co.uk /phone: /+44 (0)7961 144286 /book: /Domain Driven Design using Naked Objects http://pragprog.com/titles/dhnako /blog: /http://danhaywood.com /linked in: /http://uk.linkedin.com/in/dkhaywood /twitter: /http://twitter.com/dkhaywood /sybase: /http://sybtraining.co.uk On 19/04/2010 13:08, Jeremy Thomerson wrote: You shouldn't be committing your changes to the actual domain object until the form is submitted (your ok button).

What is the best way to use LoadableDetachableModel with a WebPage and DataView?
Hi All, I need help with a Wicket architecture design issue that I am having. In previous Wicket applications, I have used the LoadableDetachableModel in 2 separate ways: 1) In the constructor of a WebPage, an LDM is instantiated and then used as the model for a component such as a ListView. This is staight out of Wicket In Action Chapter 4 on LDMs. 2) As the model for a SortableDataProvider to be used with a DataView component. I have more or less used the WicketStuff SortingPage example as a guide. That is, the SortableDataProvider uses an LDM to supply its own backing data. For a new Wicket application, I have a WebPage that will have the following aspects: 1) A sortable grid based on the DataView component. 2) The data behind the grid is a collection of Job Application objects that is owned by an Applicant object. 3) A link somewhere else on the page will cause a new Job Application object to be added to the Applicant's list. 4) Adding the Job Application object will cause a new record to be written to the underlying database. Hibernate will be used as the persistence framework. So here is my issue: For this new application, is the correct approach to: 1) create an LDM in the WebPage's constructor that loads the Applicant object, 2) pass the Applicant object's collection of Job Applications objects to the SortableDataProvider that is used with the DataView component? Or should the SortableDataProvider use its own LDM that is separate from the one used on the WebPage? Thanks in advance, Steve

Date components
Hi All, Does anyone have any good suggestions for date/time entry components? Does Wicket offer a standard solution for this common case? Thanks, Ray Weidner
Re: Date components
You just add the following code to your java page:
*add(dateTimeField = new DateTimeField(dateEnvoi, new PropertyModel(this,
date)) {});*
Which dateEnvoi defined in the markup file (the key of the component).
And date defined in java like :
private Date date = new Date();

problem populating ListMultipleChoice selection model
Hi All,
I'm trying to do something pretty simple: create a choice list with
multi-select, which I iterate through upon clicking a button.
Unfortunately, it looks like my selections aren't being recorded in the
model that's supposed to receive them. Here's what the pertinent code looks
like:
- Java:
public EditIssuePage extends WebPage {
// I've tried removing the 'transient' keyword, but that doesn't change
anything
transient private Set Party selectedParties = new HashMap Party ();
...
public EditIssuePage () {
...
Form form = new Form (editIssueForm);
add (form);
...
ListMultipleChoice Party partyChoice = new ListMultipleChoice
Party (
parties,
new PropertyModel (this, selectedParties),
new LoadableDetachableModel List Party () {
@Override
public List Party load () {
return new Vector Party (retrieveAllPartiesFromDAO ());
}
},
new IChoiceRenderer Party () {
public Object getDisplayValue (Party object) {
return object.getFullName ();
}
public String getIdValue (Party object, int index) {
return object.getId ();
}
}
);
Button addPartiesButton = new Button (addPartiesButton) {
@Override
public void onSubmit () {
logger.debug (Number of selected parties: +
selectedParties.size ()); // always reporting zero!
for (Party selectedParty : selectedParties) {
...
}
}
};
form.add (partyChoice);
form.add (addPartiesButton);
}
private Set Party retrieveAllPartiesFromDAO () {
// does what it sounds like
}
}

front of me as I write this)
...
select multiple wicket:id=parties
option[A party should be here]/option
/select
submit wicket:id=addPartiesButton name=Add Selected Parties/
...
The page renders fine, with all Party objects listed for selection. But
when I select one or more of the rows and click the button, the log message
I see is Number of selected parties: 0, no matter what. I have very
similar logic working on another page, so I'm pretty confused about what's
the problem here. All advice is much appreciated.

I'll give that a try when I have the code in front of me. But I'd be

when I select one or more of the rows and click the button, the log
message
I see is Number of selected parties: 0, no matter what. I have very
similar logic working on another page, so I'm pretty confused about

the problem here. All advice is much appreciated.

Re: Wicket Branding with setStyle - question about static images in src/webapp/*
see ContextImage, create your own version that is style-aware. alternatively you can create tag handlers just like wicket:link that will add your own version of ContextImage for you. -igor On Sun, Apr 18, 2010 at 11:16 AM, Martin Makundi martin.maku...@koodaripalvelut.com wrote: Hi!

Re: What is the best way to use LoadableDetachableModel with a WebPage and DataView?
why all the complexity of ldm inside idataprovider, why not just:
class mydataprovider implements idataprovider {
private long applicantid;
private transient applicant applicant;
private applicant getapplicant() { if (applicant==null) {
applicant=dao.get(applicantid); }}
private iterator(..) {

private size() { return getapplicant().getapplications().size(); }

Hi All,
I need help with a Wicket architecture design issue that I am having.
In previous Wicket applications, I have used the LoadableDetachableModel in 2
separate ways:
1) In the constructor of a WebPage, an LDM is instantiated and then used as
the model
for a component such as a ListView. This is staight out of Wicket In Action
Chapter 4
on LDMs.
2) As the model for a SortableDataProvider to be used with a DataView
component.
I have more or less used the WicketStuff SortingPage example as a guide. That
is,
the SortableDataProvider uses an LDM to supply its own backing data.
For a new Wicket application, I have a WebPage that will have the following
aspects:
1) A sortable grid based on the DataView component.
2) The data behind the grid is a collection of Job Application objects that
is owned by an Applicant object.
3) A link somewhere else on the page will cause a new Job Application object
to be added to the Applicant's list.
4) Adding the Job Application object will cause a new record to be written to
the underlying database.
Hibernate will be used as the persistence framework.
So here is my issue:
For this new application, is the correct approach to:
1) create an LDM in the WebPage's constructor that loads the Applicant object,
2) pass the Applicant object's collection of Job Applications objects to the
SortableDataProvider
that is used with the DataView component?
Or should the SortableDataProvider use its own LDM that is separate from the
one used on the WebPage?
Thanks in advance,
Steve

How to validate an entire object in a form (rather than a particular property of that object)
Another form-related question. I can see how to install a validator on a Form - Form#add(IFormValidator) - but it seems that AbstractFormValidator, the adapter, always requires a specific FormComponent to be specified in its error(...) method. How does one raise an error on the state of the form (and by implication, that of the underlying domain object) itself, without having to specify any form component?

Re: Exception propagation
Okay, eventually I figured that out myself:
- so, as per the wiki, the web.xml should have the following for the wicket
filter:
filter-mapping
filter-namewicket/filter-name
url-pattern/*/url-pattern
dispatcherREQUEST/dispatcher
dispatcherERROR/dispatcher
/filter-mapping
- the WebApplication subclass would have something like this (may be
unconditional if needed for both development and deployment modes):
if (DEPLOYMENT.equalsIgnoreCase(getConfigurationType())) {
getExceptionSettings().setUnexpectedExceptionDisplay(IExceptionSettings.SHOW_NO_EXCEPTION_PAGE);
}
...
public final RequestCycle newRequestCycle(final Request request, final
Response response) {
return new ExceptionHandlingRequestCycle (this, (WebRequest)request,
(WebResponse)response);
}
- the exception handling request cycle subclass would have (again, may be
unconditional if needed for both development and deployment modes)
public final Page onRuntimeException(final Page page, final
RuntimeException e) {
if
(WebApplication.DEPLOYMENT.equalsIgnoreCase(getApplication().getConfigurationType()))
{
throw new
AbortWithWebErrorCodeException(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
} else {
return super.onRuntimeException(page, e);
}
}
Note the AbortWithWebErrorCodeException - it's not the
AbortWithHttpStatusException (which doesn't work).
- now in the web.xml you can have:
error-page
error-code500/error-code
location/xxx/location
/error-page
/xxx may be either another wicket mounted path or it may be a static
resource not managed by wicket. Now you have standard (specwise) error
handling support in the web app.

Hi, you can override the isEnable method and implement your rule, like:

Another beginner localization question
Hi,
I'm using a wicket:message tags, property files and a ChoiceRenderer
to allow users to switch the Locale. My ChoiceRenderer overrides
wantOnSelectionChangedNotifications() to have the browser send a Locale
change event to the server and when this call returns, all
wicket:message content is updated to match the new locale's messages.
This all works fine. However, I also have a DatePicker JQueryUI
component component on my page which needs to be adjusted. This is done
by having the browser execute the JavaScript:
script type='text/javascript'
$(function() {
$.datepicker.setDefaults($.datepicker.regional['_[LOCALE]_']);
});
/script
Is it possible to have the browser to execute some dynamically-generated
JavaScript using the ChoiceRenderer's onSelectionChanged() event?
Thanks in advance.

Hi Pedro,
That was my first instinct, to override isEnabled(), but it turns out

So, no joy there.
Any other suggestions, anyone?

you can override form.onvalidate() and do your validation there -igor On Mon, Apr 19, 2010 at 4:51 PM, Dan Haywood dkhayw...@gmail.com wrote: Hi Pedro, but my problem is that there is no form component to represent the form itself, is there?
