Re: [Wicket-user] Wicket-portlet inside LifeRay + Tomcat?
At least wicket-portlet-examples run fine with Liferay+Tomcat. What is this wicket-portlet-samples you're trying to deploy, and where did you get that portlet.war? If you compile the examples with maven it produces a war called "wicket-portlet-examples.war"."Exception: Error registering portlets for es.tsystems.nt.web" sounds like you're not deploying the real wicket portlet examples, may be you should try with that first?Also, which version of wicket are you using? 1.2.2 is currently the best choice.JanneOn 12.9.2006, at 18.05, Manu wrote:Has anyone successfully runned a simple Wicket-portlet inside LifeRay + Tomcat?I have downloaded the Wicket-portlet-samples from the repository, andwhen I try to load the portlet.war with LifeRay + Tomcat I get thefollowing error:---14:59:36,520 ERROR [HotDeployUtil:52] com.liferay.portal.kernel.deploy.HotDeployException: Error registering portlets for es.tsystems.nt.web at com.liferay.portal.deploy.HotDeployPortletListener.invokeDeploy(HotDeployPortletListener.java:284) at com.liferay.portal.kernel.deploy.HotDeployUtil._fireDeployEvent(HotDeployUtil.java:82) at com.liferay.portal.kernel.deploy.HotDeployUtil.fireDeployEvent(HotDeployUtil.java:43) at com.liferay.portal.kernel.servlet.PortletContextListener.contextInitialized(PortletContextListener.java:41) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3729) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4187) at org.apache.catalina.startup.HostConfig.checkResources(HostConfig.java:1089) at org.apache.catalina.startup.HostConfig.check(HostConfig.java:1187) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:292) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:119) at org.apache.catalina.core.ContainerBase.backgroundProcess(ContainerBase.java:1305) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1569) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1578) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.run(ContainerBase.java:1558) at java.lang.Thread.run(Thread.java:534)Caused by: java.lang.ClassCastException at com.liferay.portal.deploy.HotDeployPortletListener.invokeDeploy(HotDeployPortletListener.java:142) ... 14 more---Need help!

Portlet support is still experimental, meaning there has not been real production class project based on it, but it is pretty much feature complete.

[Wicket-user] How to detect page switch

Re: [Wicket-user] SubmitLink and back button...
ok, should be fixed in 1.2.3, you can try the wicket-1.x branch now if you wantfor the versioning to work properly though you need to remember changes done against your dataprovider because it keeps its own state that needs to be rolled back. attached is the
submitlinkpage.java that shows you how to do that.-IgorOn 9/12/06, Igor Vaynberg [EMAIL PROTECTED]

Re: [Wicket-user] How to detect page switch
I already tried this method, but it is called just before the user can see the page. What I need is to do something when he leaves the page. However, I think I have found an acceptable solution. I would make all my data objects implements an interface (let's say Lockable) and retain the last locked object in the session. That way, I can release the last locked object on each new request (if needed). The risk is to have the last object locked until the session expires, but that's acceptable in my use case. However, I red many times that big objects should not be put in the session. Putting an object in the session is just a matter of retaining a reference to it. So it should not cost much.

Re: [Wicket-user] How to detect page switch
Matej, I do not understand your point :-( The object does not get replicated when a reference to it is stored in the session. So I understand point b, but in case no clustering is used, why would there be a memory problem? Putting a reference in the session is just a way to keep a handle on the object. Having the reference the session is not different from having it anywhere else, as far as memory is concerned. Or is it? Pierre-Yves Matej Knopp a écrit : Putting large objects into session is ok, as long as you a) have enough memory and can afford it b) don't replicate the session (clustering). -Matej Pierre-Yves Saumont wrote: I already tried this method, but it is called just before the user can see the page. What I need is to do something when he leaves the page. However, I think I have found an acceptable solution. I would make all my data objects implements an interface (let's say Lockable) and retain the last locked object in the session. That way, I can release the last locked object on each new request (if needed). The risk is to have the last object locked until the session expires, but that's acceptable in my use case. However, I red many times that big objects should not be put in the session. Putting an object in the session is just a matter of retaining a reference to it. So it should not cost much.

Having the reference the session is not different from having it anywhere else, as far as memory is concerned. Or is it? That,, of course, depends on where that object comes from and how long lived it would be if it were not put in the session. For instance, if you have some objects you get from an ORM (like Hibernate), they typically only have to exist for a short time, e.g. during a transaction, interpreting the results of a query, etc. Usually, this means that such objects live for one request. However, if you references to such objects in your components or models, they'll live as long as those components/ models live, which might be for the duration of the session. But if you would store e.g. only the ids of those objects, or the query to get them or just a reference to a service that knows how to get them, you'll use less memory. This is the main reason we have detachable models. Replication, like you said, only happens when you run in a cluster *and* you use http session replication *and* you use http session as session store (HttpSessionStore) *or* when a server tries to persist sessions e.g. on shutdown so that on startup it can pick up it's sessions again.

Re: [Wicket-user] Ajax request 'hangs' on Safari - problem found (Wicket 2.0)
Problem found, it looks like safari aborts execution when
getElementsByTagName
is called on a text node (in contrast calling e.g. 'childNodes' works
fine.)
The problem occurs in the Wicket.Head.addJavascripts (called from
Wicket.replaceOuterHtml) function
when one of the elements is a text node. A fix could be to check for
the node type of the element or
childNodes.lenght 0 before element.getElementsByTagName(script)
is called.
Do you have another solution or can I file a bug for it?

The most general constructor is public Image(final String id, final Resource imageResource) In this way you can determine for yourself where it gets the input from. Perhaps BlobImageResource or its super class DynamicImageResource are good resource implementations for this.

[Wicket-user] polymorphic components...
Hi all,
In the application I am writing I have encountered a need for
polymorphic components. That is, in my markup I have
span wicket:id=blahcontent/span
and depending on what component is used on the server side, I can add
links, labels, or anything else you can imagine. The only requirement is
that the component provides its own html. This is very useful for
instance for dynamically generating content such as dynamic menus based
on user privileges where the menu items consist of plain text, links,
images, etc
As an example I have attached a LinkPanel. The programmer has to create
a subclass and implement
/**
* Must be implemented to create the content of the link.
* @param aId Id of the component to create.
*/
protected abstract Component createContent(String aId);
/**
* Callback to notify the user of onClick events.
*
*/
protected abstract void onClick();
The first callback is simply to create the content. The second is to
notify of onclick events. The html template for the component is very
simple, just an anchor and the content of the anchor.
Are a range of components like this a good idea for inclusion in
wicket-extensions?
Cheers
Erik

Thanks for sharing,
What we would like to promote more actually is the fact that creating
your own patterns/components is (or at least should be) pretty damn
easy with Wicket. So in this case, a WIKI or blog item is probably
more helpful. However, if you feel you have something that'll save
users a lot of time, or will inspire them with their Wicket work,
you're free to start up a wicket-stuff project (send me a personal

Re: [Wicket-user] polymorphic components...
i think all these little wrappers for consistent-ui will be unique to every application. i have them for all applications im working on and they are really trivial, but more importantly really different between the applications, so i think having a set of these for extensions will not be very helpful.

Re: [Wicket-user] How to detect page switch
Thank you for this clarification. So it appears that, in an unclusterd context, the problem is not with storing references *in sessions*, but simply with storing references. I am using hibernate objects and I need to keep to copies of the data, so I am creating a value object plus I keep the original hibernate object. Perhaps I would better create 2 value objects and throw away the hibernate object (in case this object is much bigger than a simple value object??). I must check for this. (But this is not Wicket related ;-). Thanks again Pierre-Yves Eelco Hillenius a écrit : On 9/12/06, Pierre-Yves Saumont [EMAIL PROTECTED] wrote: Matej, I do not understand your point :-( The object does not get replicated when a reference to it is stored in the session. So I understand point b, but in case no clustering is used, why would there be a memory problem? Putting a reference in the session is just a way to keep a handle on the object. Having the reference the session is not different from having it anywhere else, as far as memory is concerned. Or is it? That,, of course, depends on where that object comes from and how long lived it would be if it were not put in the session. For instance, if you have some objects you get from an ORM (like Hibernate), they typically only have to exist for a short time, e.g. during a transaction, interpreting the results of a query, etc. Usually, this means that such objects live for one request. However, if you references to such objects in your components or models, they'll live as long as those components/ models live, which might be for the duration of the session. But if you would store e.g. only the ids of those objects, or the query to get them or just a reference to a service that knows how to get them, you'll use less memory. This is the main reason we have detachable models. Replication, like you said, only happens when you run in a cluster *and* you use http session replication *and* you use http session as session store (HttpSessionStore) *or* when a server tries to persist sessions e.g. on shutdown so that on startup it can pick up it's sessions again.

A common problem with things like Hibernate objects is that they might get stale (disconnected from the session they were retrieved in), which results in problems with things like lazy collections. Also, if you use a transaction per request (e.g. using servlet filters or a custom request cycle) like some people have reported doing, you have to be very careful you're not updating objects you didn't want updated. The latter is an argument for using value objects (which I don't like tbh... too much code duplication) and the first is an argument for using detachable models and thus storing only the minimal info (if any) for retrieving the proper objects.

[Wicket-user] Radiogroup without listview
Hi
do i need to always use radiogroup with listview?
i used it without listview but my radiogoup model is not updating.. here is
code
RadioGroup rg = new RadioGroup(group, new Model());
Radio r1 = new Radio(radio1, new Model(no));
Radio r2 = new Radio(radio2, new Model(yes));
rg.add(r1);
rg.add(r2);
i understand that on form submit the selected radio button model will be
attached to group.
so
public vois onSubmit(){
group.getModelObject(); // here i expect the selected radio button model
.. but i get null..
}
what is wrong with this code?
cheers,

Re: [Wicket-user] Dyanmic component's model
depends on what you want to do with it, if you want the input to go back into the question you can just doitem.add(new TextField(inputText
, new PropertyModel(item.getModel(), questionText));-IgorOn 9/12/06, Joshua Lim

I am trying to create a set of dynamic components that will generate dynamic numbers of input components, but I got stuck in providing a model for it.for e.g. I have TextGroupPanel - which will create a series of TextField
RadioGroupPanel - which will generate a Grid type of Radio buttons.. etc ...Generating it is not a problem, I have a problem though with providing the models for each (dynamic numnber) of Text/Radio components
I know I'll probably need a hashMap to handle that, but not sure of the best approach so that this component can be reuseable...any suggestion would be most welcomed/** Text Group **/public class TextGroupPanel extends WidgetPanel
public TextGroupPanel(String id, final IQuestion question) { super(id, question); add(new Label(questionText, question.getText()));
