 Hi Chris,
 Have you tried the following?:
 
 
 
 In my case, the above solution was not properly redirecting to external url
 in production mode, so I resorted to using RedirectToUrlException:
 
 
 
 On the onSubmit(), I then called  setResponsePage(new RedirectPage(
 external url ) );
 
 I hope this helps.
 Regards,
 Lucas

Re: Browser back - reload page/panel

2015-04-22 Thread Martin Grigorov

Hi,

Wicket disables caching for the pages [1] so going back will make a request
for re-render.
You should use dynamic models [2] to re-render the latest state.

Re: Storing data in wicket session

2015-04-22 Thread Martin Grigorov

Hi,

On Wed, Apr 22, 2015 at 4:48 AM, Chris chris...@gmx.at wrote:

 Hi all,

 I need so share a list of strings between some objects during a session;
 Within the session, the list of strings will be deleted based on specific
 requests.

 Currently, I store them in the page but the disadvantage of this approach
 is that I have to delegate the list to each sub(sub)component.


You can create a helper class: PageHelper#getMyList(Page page) { return
((MyPage) page).getMyList();}
And use it in any component: MyList myList =
PageHelper.getMyList(getPage());



 Would it be good practice to store this directly in the wicket session?
 How to do this?


Yes. Just create a property/getter/setter in MySession and then use it:
((MySession) Session.get()).getMyList();
Make sure you synchronize the access to the list!



 A second approach would be to store it in the user object and inject this
 object in the individual components.


This is also an option. It could be a session scoped bean, or a provider...



 Could you give me a recommendation?

 Thanks, Chris

Re: Browser back - reload page/panel

2015-04-22 Thread Chris

Martin, thanks for the tip.

I would like to use some dynamic List Model, but not a detachable one and put 
following in the page’s initialization method:

  IModelListSomeType poisModel = new ListModelSomeType() {
@Override
public ListSomeType getObject() {
return service.retrieveList();
}

Why is the service.retrieveList method called so often, I thought that this 
call should be only made once?
Should I use another model?

Re: Browser back - reload page/panel

2015-04-22 Thread Chris

Hi Sebastian,

thanks - but if the page has many subcomponents that consume the model then 
there would be many subsequent calls? The service call might be expensive, 
isn’t it?
Is there another solution next to loadable detachable model? I could use a 
static model if the model does not change during a request…

You said that the #getObject should not be overridden in this way:
When to recommend it? The example below uses this approach:

personForm.add(new RequiredTextField(personName, new Model() {
@Override
public Object getObject() {
return person.getName();
}
 
@Override
public void setObject(Serializable object) {
person.setName((String) object);
}
}));

To getObject, yes. But if you use a (shared) LDM it doesn't matter.


 The service call might be expensive, isn’t it?


Yes, probably.


 Is there another solution next to loadable detachable model?


It depends of your use case, you can do what you want with models
(including writing yours of course)
But for your use case, a LDM should suit...


 I could use a static model if the model does not change during a request…


Not sure what you mean by static model...



 You said that the #getObject should not be overridden in this way:
 When to recommend it? The example below uses this approach:

 @Override
 public Object getObject() {

 }
 }));


The example is correct... There is a difference between
service.retrieveList and person.getName(): the latest being is an atomic
call while the first is potentially time consuming.
That's exactly one of the two reason why the LDM as been written :) (the
second being it is automatically detached...)

Re: Browser back - reload page/panel

2015-04-22 Thread Martin Grigorov

See the implementation of LoadableDetachableModel. It caches the result for
the request lifetime. That's why it calls getObject() just once
On Apr 23, 2015 1:56 AM, Chris chris...@gmx.at wrote:

 Hi Sebastian,

 With „static“ I mean something as follows: model = new
 ListModelSomeType(service.retrieve());

 I do not quite understand why the subsequent calls do not matter when
 using a LDM.
 If I use an LDM and a component of the page uses this model (e.g. creating
 a new Panel) then the service method is called again and this has a
 negative impact on performance if the database is hit all the time. With
 the line above this does not happen.

 thanks for your feedback!

With „static“ I mean something as follows: model = new 
ListModelSomeType(service.retrieve());

I do not quite understand why the subsequent calls do not matter when using a 
LDM.
If I use an LDM and a component of the page uses this model (e.g. creating a 
new Panel) then the service method is called again and this has a negative 
impact on performance if the database is hit all the time. With the line above 
this does not happen.

thanks for your feedback!
Chris

 Hi Chris,
 
 thanks - but if the page has many subcomponents that consume the model then
 there would be many subsequent calls?
 
 
 To getObject, yes. But if you use a (shared) LDM it doesn't matter.
 
 
 The service call might be expensive, isn’t it?
 
 
 Yes, probably.
 
 
 Is there another solution next to loadable detachable model?
 
 
 It depends of your use case, you can do what you want with models
 (including writing yours of course)
 But for your use case, a LDM should suit...
 
 
 I could use a static model if the model does not change during a request…
 
 
 Not sure what you mean by static model...
 
 
 
 You said that the #getObject should not be overridden in this way:
 When to recommend it? The example below uses this approach:
 
 personForm.add(new RequiredTextField(personName, new Model() {
@Override
public Object getObject() {
return person.getName();
}
 
@Override
public void setObject(Serializable object) {
person.setName((String) object);
}
 }));
 
 
 The example is correct... There is a difference between
 service.retrieveList and person.getName(): the latest being is an atomic
 call while the first is potentially time consuming.
 That's exactly one of the two reason why the LDM as been written :) (the
 second being it is automatically detached...)
 
 
 
 Thanks, Chris

 Hi Chris,
 
 #getObject is potentially called often, yes. You should never override
 #getObject() like this
 A dynamic model is a LoadableDetachableModel. Overrides #load and it will
 be called only once by server request, at each server request (that
 consumes the model, of course).
 
 Hope this helps,
 Sebastien.

 Martin, thanks for the tip.
 
 I would like to use some dynamic List Model, but not a detachable one
 and
 put following in the page’s initialization method:
 
 IModelListSomeType poisModel = new ListModelSomeType() {
   @Override
   public ListSomeType getObject() {
   return service.retrieveList();
   }
 
 Why is the service.retrieveList method called so often, I thought that
 this call should be only made once?
 Should I use another model?
 
 Thanks!

 Hi,
 
 Wicket disables caching for the pages [1] so going back will make a
 request
 for re-render.
 You should use dynamic models [2] to re-render the latest state.

 Hi all,
 
 how is it possible to refresh a page or panel on browser back? If the
 user
 deletes an item and clicks on browser back to go to the last page, it
 is
 still displayed which should not be the case.
 
 Thanks a lot,
 Chris

Simple message solution Wicket-Spring combined application

2015-04-22 Thread Sandor Feher

Hi,

I'm looking for a simple and feasible message sending solution for my
application.
The main goal is that components (both wicket and spring) should be send
messages if a specific event occurs to users.
The message will be displayed at top of the page with help
AjaxSelfUpdatingBehaviour.
Spring messages are system wide. (Eg. all users should be notified) while
wicket ones can be session wide.
Wicket's event mechanism can be fine but my Spring based web service does
not know anything about wicket sessions (and should not of course).
I can do it via database table but I will cause overhead because of two
seconds refresh time I set in AjaxSelfUpdatingBehaviour.
So I'm looking for a more lightweight approach.

Thanks!

Regards., Sandor

Re: Simple message solution Wicket-Spring combined application

2015-04-22 Thread Martin Grigorov

Hi,

The session services could store messages to application scoped bean.
The Wicket components in either the Wicket Session or session scoped bean.
The AjaxSelfUpdatingBehaviour will check both.
The session scoped messages could be deleted after render but you have to
think of a way how to mark an application scoped message as read by a
client and delete it when all it is read by all clients.

Re: Simple message solution Wicket-Spring combined application

2015-04-22 Thread Sebastien

If you are looking for another approach, you can give a try to native
websockets.

In the java sample below, the business tier is triggering a listener event,
which received by the web tier, which sends the websocket message.
Client side, the page is registered to the websocket by a Behavior. When a
message arrives, it is displayed.
The scope of the websocket message broadcast can be controlled IIRC
(Session, Application).

Wiki:
https://cwiki.apache.org/confluence/display/WICKET/Wicket+Native+WebSockets

Sample (scala)

Re: Submitlink + PageParameters

Hi Chris,
Have you tried the following?:



In my case, the above solution was not properly redirecting to external url
in production mode, so I resorted to using RedirectToUrlException:



On the onSubmit(), I then calledsetResponsePage(new RedirectPage(
external url ) );

I hope this helps.
Regards,
Lucas
