Listening key pressings on server side
Hello,
I'd like to know whether there is a way to listen certain key pressings (key
a,>,1,...) on server side in wicket.
I've tried
.html:
.java
body = new WebMarkupContainer("body");
body.add(new AjaxEventBehavior("onkeypress"){
protected void onEvent(final AjaxRequestTarget target) {
LOG.debug("keypress");
}
});
Problem here is that event is generated only for "onclick" event, in case of
"onkeypress", nothing happens.
And even if I would be able to catch the "onkeypress" event, I'd still have
to figure out, which key was pressed.
And also I've tried wicket-contrib-input-events
add(new InputBehavior(new KeyType[] { KeyType.Left },
EventType.click));
add(new AjaxEventBehavior("onclick"){
@Override
protected void onEvent(AjaxRequestTarget target) {
LOG.debug("Clicked left");
}
});
But problem there is that EventType.onkeypress is not supported.
Examples I made on main page, but eventually I would need to listen key
pressings on modalwindow's panel, which is placed on a page.
Thanks in advance,
Roland
Hook into RequestCycle ?
Hi,
what is the best place to hook into the request cycle
before a page gets processed ? I looked through
http://cwiki.apache.org/WICKET/lifecycle-of-a-wicket-application.html but
the
information there seems to be a bit outdated ("the Session returned by the
Application
is asked to create a RequestCycle object using the Session's request cycle
factory",
but there's nothing like a request cycle factory which can be obtained from
a Session in 1.3)
Is there a more accurate documentation of a request's lifecycle somewhere
else ?
My use case is as follows: Before any page is processed I want to look up in
the Session,
whether a user is authenticated. If not, it is checked wheter a certain hash
stored in a Cookie
(if any) is stored in the DB and the associated user then is put into the
session, providing some sort
of 'keep me logged in' functionality. (The 'remember me' feature of the
SignInPanel is not enough for
me, since I want a transparent login without moving over the login page). Of
course, if there is already
support for this kind of feature out of the box somewhere, I would be happy
for getting a pointer, too.
thanx ...
... roland

Why dont you simple use MessageFormat's parameter substitution as desribed
in the JavaDoc, i.e.
.. new StringResourceModel("label.getTotalAlbums",this,null,new Object[] {
getTotalAlbums() });
with
label.getTotalAlbums=All Albums: ${0}
Alternatively, I you need late binding put
new AbstractReadOnlyModel() {
public Object getObject() { return getTotalAlbums(); }
}
in the object array (instead of getTotalAlbums() directly)
bye ...

You got it. ('late binding' is probably the wrong synonym here, but it's a
good metaphor anyway.
At least for me ;-) Instead of showing only the number of total albums which
existed
at creation time of your component, by using this extra indirection step you
get
your method evaluated each time the component is rendered (which can happen
quite later
when your album collection changes, e.g. when you use this label on a page
where you
manage your stuff).

There is not way to provide a automatic sign in since this can be only be done via signIn(username,password) on AuthenticatedWebSession. It would be possible if AWS.isSignedIn() wouldn't be final, so one could dynamically check for the cookie (and not only for a previous occured manual authentication). The solution I've chosen right now is to set an own UnauthorizedComponentInstantiationListener in my AuthenticatedWebApplication which copies over 90% of the existing functionality. This is certainly not an ideal solution. In general, I'm a fan of final methods, too in order to restrict unwanted extension points, but for AWS.isSignedIn() it would be probably a good idea to allow overriding or at least to provide and additional hook to relax the restriction to work with manual authentication via AWS.signIn() only. If you don't mind, I would like to open a JIRA issue for an RFE (with some more code examples).

Re: Business/Domain objects used as wicket model object - opinions please
Except for rather small scoped projects, I prefer the usage of DTOs (or formerly known as 'View Objects') over direct usage of domain objects. DTOs can be modelled much closer to the use case (i.e. view) at hand (by combining domain objects or leaving out non-required attributes to have objects like e,g 'UsersAndTicketsVO'). If you are using an ORM tool like Hibernate there are some additional technical issues, if you intend to let the mapped domain objects propagate to the view layer: * LazyInitializationException issues (no more words on this here ;-) * Serialization can bite you in remote access scenarios (not very probable for a web application, though) because of the implicite dependency on some implementation classes like a HibernateSession. * Subtle but severe problems when you have to 'prepare' domain objects for the view, e.g. for security reasons. Consider a scenario where a user are only allowed to see some parts of a domain objects, e.g. a 'Protocol' which has 'ProtocolEntry' members where some of them are classified. If you now remove the classified 'ProtocolEntry' members before showing the protocol entries in a list view, and this happens within a Hibernate Session's boundary, then this entries will be removed from the DB as well (without an explicit call to some DAO). We use DTOs also for an addition abstraction layer (a facade), which provides use-case (client) specific service methods (with DTOs as arguments) and call out to domain specific services (hidden by interfaces of course) with domain objects on the other side. BTW, I had to learn all those things 'the hard way', so this is not a pure theoretical argumentation. Formerly, I was a firm advocat of 'avoiding DTOs at all cost', too ;-) If you need some tool support for using view objects (and to cut down the LOCs ;-), we find Dozer (http://dozer.sf.net/) for declarative, bean-wise mappings rather useful. ... roland Martijn Dashorst wrote: > > You could do that.

wicketstuff-push and component replacing
Hello,
I'm currently developing wicket based application, which displays alarms on map
and allows their modification.
New alarms are sent to server through soap service and map with few other
components on page for all browser clients needs to be refreshed.
I'm using wicketstuff-push for the push service implementation.
org.wicketstuff.push.timer.TimerPushService to be clear.
As an in examples I have method on wicket page which is activated when server
sends notification about an event:
// set new listener for incoming events
final IPushTarget pushTarget =
getTimerPushService().installPush(this);
getPushService().addMapListener(new
MapServiceListener() {
public void onEventChange(final Event event) {
if
(pushTarget.isConnected()) {
Label label = new Label("labelonpage","label"); //label to
be replaced
pushTarget.addComponent(label);
pushTarget.trigger();
}
else { // remove inactive listener
LOG.debug("Removing map listener " + this);
getPushService().removeMapListener(this);
}
...
Problems start with line :
Label label = new Label("labelonpage","label");
which results with:
org.apache.wicket.WicketRuntimeException: There is no application attached to
current thread btpool0-2
at org.apache.wicket.Application.get(Application.java:179)
at
org.apache.wicket.Component.getApplication(Component.java:1323)
at org.apache.wicket.Component.(Component.java:920)
It seems that in this push method, context is lost, I have no session,
request,...
Is there any way I gan regain it or make new?
Or how should I implement push service, which needs to replace some components
on page?
Thanks in advance,
Roland

you will need to override newNodeComponent(final String id, final

here is a complete example with post exactly the same only you acces the

StringValue parameterValue =

replace getRequestCycle().scheduleRequestHandlerAfterCurrent
Hi we're using getRequestCycle().scheduleRequestHandlerAfterCurrent,
various places in our application which causes 500 error, is there any we
to replace, lines below because my solution which is:
String url = RequestCycle.get().urlFor(rs).toString();
throw new RedirectToUrlException(url);
doesn't work.
///
ResourceStreamRequestHandler rs = new ResourceStreamRequestHandler(
new StringResourceStream(work, "text/csv"));
rs.setFileName("Workdone_" +
projectModel.getObject().getName().replaceAll("[^a-zA-Z0-9]", "") + ".csv");
this.getRequestCycle().scheduleRequestHandlerAfterCurrent(rs);
or another example I was trying to replace
ResourceStreamRequestHandler rs = new ResourceStreamRequestHandler(new
FileResourceStream(new File(file.getAbsolutePath(;
rs.setFileName(df.getFileName());
this.getRequestCycle().scheduleRequestHandlerAfterCurrent(rs);
with this, but doesnt work either:
String url = (RequestCycle.get().urlFor(rs)).toString();
throw new RedirectToUrlException(url);
thanks for any help

Re: replace getRequestCycle().scheduleRequestHandlerAfterCurrent
It seems we cannot reproduce this locally - only in production. Difference
being apache is in front of tomcat. If we comment out the following code we
have no issues:
setPageRendererProvider(new IPageRendererProvider() {
@Override public PageRenderer get(final RenderPageRequestHandler
context) {
return new WebPageRenderer(context) {
@Override protected RedirectPolicy getRedirectPolicy()
{
RedirectPolicy result;
if (!((WebRequest)
RequestCycle.get().getRequest()).isAjax() && (context.getPage() instanceof
ExternalShareSecurePage || context.getPage() instanceof
ExternalShareDocumentPage)) {
result =
RedirectPolicy.NEVER_REDIRECT;
} else {
result = super.getRedirectPolicy();
} return result;
}
};
}
});
