Any idea what can be wrong?
yes ... your modal window has to be put into a form, so the panel's form
is nested:
Example:
public class TrackerGroupsPanel extends Panel {
@SpringBean
private FleetServicefleetService;
@SpringBean
private TrackerService
condition in AbstractAjaxTimerBehavior
Hi
I need to periodically update a page unless some condition is met.
I wrote javascript function canRefresh() and added like this:
add(new AbstractAjaxTimerBehavior(Duration.seconds(5)) {
@Override
protected void onTimer(final AjaxRequestTarget target) {
updateSessionConfigPanel(target);
}
@Override
protected CharSequence getCallbackScript() {
return if (!canRefresh()) {+ super.getCallbackScript()+};;
}
});
This is generated javascript.
script type=text/javascript !--/*--![CDATA[/*!--*/
Wicket.Event.add(window, load, function(event) { setTimeout(if
(!canRefresh()) {var
wcall=wicketAjaxGet('?wicket:interface=:0::IActivePageBehaviorListener:1
:wicket:ignoreIfNotActive=true',function() { }.bind(this),function() {
}.bind(this));};, 5000);;});
/*--]]*//script
The problem is that once canRefresh() returns false timer stops. Is it
possible to restart it? Or a better way to implement conditional
update?

new release of wicket-contrib-javaee
hi I have just created a new release of wicket-contrib-javaee. I have fixed POM file and made it compatible with wicket 1.3. Here is wiki page http://wicketstuff.org/confluence/display/STUFFWIKI/wicket-contrib-javaee And to answer your question about EJB references in web.xml. They are required because we need to lookup EJBs to create proxies for them. In JSF it's responsibility of app. server to inject EJB references. Maris if you use EJB3 you really want to use the wicket-contrib-javaee project (wicketstuff) all you need to do is call you @EJB and rest is handled automatically ! That project needs an update for 1.3 Add wicket-ioc dep / remove spring dep + some other unneeded deps / fix package names, I contacted the author but got no response. Plus you have to define all beans in the web.xml which is not needed when you work with jsf for example (tested on glassfish). Does anybody know why that is? but since this thread is about jpa+guice+wicket on lightweight container and not j2ee + wicket I suppose that wicket-contrib-javaee is not what they are looking for. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: WicketServlet vs. WicketFilter
also wicket filter is much better at handling /* mapping The only problem with this mapping is that filter is invoked for all requests that fetch static web resources (css, images, etc). I may be wrong but I don't think it's good for performance. Especially if you use some other filter, for example, OpenEntityManagerInViewFilter which opens a JPA session for each request.

Re: JPA best-practices?
Let's remember good old EJB's. Inject an EntityManager in a session bean facade and EJB container will handle all concurrency issues. No need to write any boilerplate code. BTW I have seen that some people use OpenEntityManagerInViewFilter and map it to url pattern /*. It seems that an EntityManager would be created every time a static web resource is accessed. Isn't that terrible ? Maris Uwe Schäfer wrote: i plan to use JPA together with Wicket. Are there any battle-proven best-practices out there of how to handle EnityManagers and Transactions? What do other people use (no, not the spring crowd ;) ? One EntityManager per Request seems to be the obvious idea and a guice Provider may help with that. Does anyone have serious experiences with that or other suggestions? Subclass WebRequestCycle, and construct it with an EntityManager. In onBeginRequest(), create a transaction, storing it in a private variable. In onEndRequest(), commit the transaction if it hasn't already been rolled back and clean up the EntityManager. In onRuntimeException(...), rollback the transaction and then return super.onRuntimeException(...). You'll need to inject a ProviderEntityManager into your WebApplication subclass such that you can call .get() on it when you make your custom WebRequestCycle. You'll need to configure that provider in a Guice module somewhere, obviously. You should be able to figure that out. ;-) How do you inject things into your WebApplication? Well, you can use the new GuiceWebApplicationFactory, which unfortunately didn't quite make it into 1.3.0-rc1 but is in trunk. However, you can copy that class from trunk and use it in your own project quite happily - it has no extra dependencies. If you need to integrate with your container-managed JTA transactions you'll need something a little different (the container may well start and commit the tx for you), but the principle is roughly the same. Alternatively, you can take Wicket out of the picture and do stuff using a ServletFilter (like Spring's OpenEntityManagerInView).

Re: [RFE] getMarkupId()
is it a joke ? In that case web design templates would need a unique class attribute for each element that is going to be used via Ajax. And in some cases it's not possible at all. For example, odd rows in a table might have a different color than even rows. Typically one kind of rows have the same class attribute. If wicket will use class attribute as an identifier then there will be no way to work with table rows. And it's just an example. In every web design there are many html tags with the same class attribute. Maris We are going to stop using ids and move over to class as it make re-use easier and avoids a number of wicket problems with ids... The HTML monkey is not happy though. He reminds me of the Family Guy screaming monkey today. Alex Objelean wrote: This is about how wicket generates dynamically markupID.

Re: [RFE] getMarkupId()
I use ajax as well, but I don't understand what's the problem with setOutputMarkupId ? In any case I am sure that forcing unique class attributes will create much bigger problem. Almost any non trivial web design uses identical class values in many places. Sometimes CSS class is used just to specify background color or something that is applied to many html tags. Are you saying that it's going to be impossible ? I am afraid that many developers (including me) won't be able to use wicket anymore. Maris So you use it just because of the performance of the browser DOM? Not because it has to be unique? Are you using Ajax? ie forced to do setOutputMarkupId? We are and that is probably the biggest reason we are trying to avoid them.

Re: [Wicket-user] Wicket requiring one of my Spring managed beans to have a default constructor
Actually it's a problem if @SpringBean annotation creates new objects of
class that is supposed to be a *singleton*.
Is it really impossible to create a proxy class without creating a new
object of delegatee ?
Here is a discussion we had about it:
[23:10] Smike I just noticed that @SpringBean creates a new instance
of my Spring bean
[23:10] Smike it's not good, after all Spring pojos are supposed to be
singletons
[23:11] Hali_303 Smike: it should not create a new instance if the
Spring bean is a singleton
[23:12] Smike it does
[23:12] Hali_303 Smike: not all Spring beans are singletons, far from
it. Spring has many scopes, singleton scope is just one out of many scopes
[23:12] Smike it's default, isnt it ?
[23:12] Hali_303 yes
[23:13] Hali_303 how do you know that it's creating multiple instances?
[23:13] Smike my beans have default scope
[23:14] Smike breakpoints in constructor and logging statements
[23:14] Smike and I have seen the same issue discussed in mail list
[23:14] Smike where Igor says cglib needs to create a new object
[23:15] Smike so every bean needs a default constructor
[23:15] Hali_303 could you give me a pointer to this discussion?
[23:16] Smike here is the title [Wicket-user] Wicket requiring one of
my Spring managed beans to have a default constructor
[23:18] Smike it should only lookup a bean from spring context, why
it needs to create a new object... I have no idea
[23:18] Hali_303 Smike: yeah I think what Igor says is right
[23:19] Smike why it can't use existing object ?

[23:19] Hali_303 Smike: yeah exactly, I don't really see the
connection between that thread and your problem
[23:20] Hali_303 the guy in that thread did not complain about
multiple instances of singleton beans
[23:20] Smike the problem is that @SpringBean creates a new class
[23:20] Smike and that thread only confirms that
[23:21] Hali_303 it's not SpringBean, its cglib that creates one
[23:21] Hali_303 and should create it only once, not every time use
inject the bean
[23:21] Hali_303 and should create it only once, not every time use
inject the bean
[23:21] Smike yes, @SpringBean annotation creates a proxy based on cglib
[23:22] Smike ok, but I can't believe that there is no way to
create a proxy without creating a new class
[23:23] Smike of course, I am not reflection expert
[23:24] Smike but I think it's possible
[23:24] Smike at least with JDK proxy class
[23:24] Smike I have never used cglib though
[23:25] Smike so I think this is important issue and should be fixed
[23:26] pertl Smike: I remember having a similar issue when using a
bean without interface...maybe it's related to your issue... I got
multiple instances of one singleton bean... once I used the interface /
implementation pattern (UserDAO + UserDAOImpl) everything worked...
[23:26] Smike yes could be
[23:27] pertl Smike: give it a try ... use the interface but let
spring instantiate the implementation class... maybe it works out
[23:28] Hali_303 I'm using that too, and it works
[23:28] Hali_303 I've even used prototype beans and that worked too
[23:28] Smike sounds good, ok, I'll try
you have to have an empty constructor. afaik it doesnt have to be
public. this is so that cglib can create a proxy, i dont think there
is a way around it.

I am using the @SpringBean annotation to instantiate Spring
dependencies in my wicket pages but I have one page that is giving
me a error that I'm having trouble dealing with. Here's an example.
The Wicket page class:
public class Viewer extends WebPage {
@SpringBean(name = contentSettings)
private ContentSettings contentSettings;
@SpringBean(name = learningItemRepository)
private LearningItemRepository learningItemRepository;
public Viewer() {
//add some simple components to the page
}
}
The vast majority of the time, my Spring managed beans are
implementations of interfaces and not standalone concrete classes,
however, in this particular situation I have about a dozen or so
beans that don't need to follow that pattern.
LearningRepository is an interface with a concrete
implementation. ContentSettings on the other hand is a
standalone concrete class. Both classes are properly setup in my
Spring configuration xml files and I have a suite of unit tests
which load the classes using Spring so I know that they should
work. In fact, LearningRepository does work fine, but I'm
getting an error from Wicket with regards to the the
ContentSettings class:
-
java.lang.IllegalArgumentException: Superclass
