Re: sessionsize of requestlogger
Another observation that I noted is that components contain a reference to
their raw markup.
The markup which I used to code it. It is actually stored in the
httpsession.
Is This Correct?
For example, I see this in my debugger.
var $sxi = jQuery.noConflict();
$sxi(function() {
jQuery('#list1a').accordion({autoheight: false});
})

Re: sessionsize of requestlogger
As an added observation, sessionsize of deployment mode is much lower than in development mode.

sessionsize of requestlogger
Hi Everyone, RequestLogger - time=103,event=Interface[target:AjaxPagingNavigationLink(userListForm:userGroupContainer:userGroupCheckGroup:ajaxPagingNavigation:navigation:9:pageLink), page: com.ccti.base.web.usergroup.VedUserGroupPage(2), interface: IBehaviorListener.onRequest],response=PageRequest[com.ccti.base.web.usergroup.VedUserGroupPage(2)],sessionid=kdrq2wp0eaea,sessionsize=212417,sessionstart=Mon Jan 12 23:24:44 CST 2009,requests=14,totaltime=7024,activerequests=1,maxmem=66M,total=18M,used=14M sessionsize=212417 I'm particularly interested of the sessionsize that is being logged by the requestlogger. I was wondering what size does it contain? In One of My List Pages, It increases by about 72000 when I put in an ajaxpagingnavigator. I was just wondering what things are put into the session? One thing that bothers me though is I tried using a LoadableDetachableModel in my dataview. It returned the almost the same sessionsize for a dataview in which I used a CompoundDetachableMOdel. I tried viewing the page map using eclipse's debug, I can see that it keeps a reference to the previous page, so does it mean that Wicket always keeps the last page available in the HttpSession? or does it keep the current page in the session. If I try exploring the session, I can see that the loadableDetachableModels model object cannot be viewed. And the compoundpropertymodel's attributes can be viewed. As far as I can see, the wicket components consume significant session size . Please correct me if I am wrong. So question is, What Page Does Wicket Store in its HttpSession? How Many Pages Does It Store? What consumes significant session size in wicket? Is it bad to keep a reference to the previous pages in instance variables of new pages?

Re: Getting Previous Page (Help)
Is This A Possible Approach
logger.debug(getPageMapEntry().getNumericId() + "");
logger.debug(getCurrentVersionNumber() + "");
sxiForm.add(new Link("backButton") {
@Override
public void onClick() {
// TODO Auto-generated method stub
setResponsePage(getPageMap().get(pageId,
pageVersion));
}
});
Instead of passing the page, I passsed the page id and the page version.
That's what I used to retrieve the previous page?
Seems to work since session size remained at 60k
Before it would double in the 2nd page.

Getting Previous Page (Help)
Hi, We have this application and each page has a wizard like functionality in which you filll up this page first, and then go to the next page. Each page I have has about 50k used in memory according to the RequestLogger. The current solution I have right now to go to previous page is to pass the instance of the current page and store it as an instance variable in the next page. As I traverse from one page to another, my session usage goes up drastically since each page I have stored has an access to its previous page. At this rate I have sessionusage of about 300k in some situations which we cannot afford because of a lot of users. I looked at secondlevelache sessionstore and it has a secondlevelcachepagemap which I wanted to use but can't because it is private. If I would be able to have another method of fetching the previous page, then I can keep my session size to be about 50k per page. What's the most efficient way of doing this?

SessionStore and Detachable Models
hi everyone, if i use the secondlevelcachesessionstore wicket writes session state into the disk instead of the httpsession right? It is also the one that is used by default. so is it safe for me to not use abstractdetachablemodels and just use compoundpropertymodels since memory is not that big a concern anymore -- View this message in context: http://www.nabble.com/SessionStore-and-Detachable-Models-tp19548105p19548105.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Jquery Attached Behaviors Disappearing During Ajax Calls
Hi,
I'm using JQuery together with Wicket. I have this problem that whenever I
update a component through ajax, the behaviors I attached using jquery
disappear already.
For example I have a textbox which has this
$('textbox').click(function() {
alert('hello')
})
This would work while the textbox has not yet been updated.
But whenever the component has been replaced by Wicket
target.addComponent(textbox)
It will be replaced by a new component and the behavior that was binded is
no longer there.
Is there a workaround to this?
Thanks
Carlo

Re: Wicket, Hibernate and Models
What should I use when I am accessing hibernate?
Should I use a ListView or should I use a refreshing view?\
In the api it says to use refreshingview instead of using listview when
using database collections
what is better to use?

Wicket, Hibernate and Models
Hi everyone,
I have been reading wicket in action recently and I have seen pitfalls of
hibernate section.
I was wondering about the stuff about hibernate and memory leaks due to
hibernate proxy objects maintaining a reference to the session with them
Am I doing this wrong then?
@SpringBean
private UserService userService;
add(new ListView("user", userService.findUsers() {
})
is this wrong? I'm using it directly meaning it will be stored in the page
store right?
should i be doing this instead?
LoadableDetachableModel model = new LoadableDetachablemodel() {
Object load() {
return usrService.findUsers()
}
}
}
add(new ListView("listView", model)) {
}
this is to avoid storing the users in the session...
will doing the first one actually result in a memory leak?
thanks

wicket Jquery Weird Behavior
Hi guys I've just found this out...
When I use the $ function of jquery directly within my page, it's causing my
page to be cosntructed twice.
I included something like
$(function() {
$('#leftFrame').css('z-index', 200);
});
It's causing my page to reload twice.
I was trying to find out what's causing my page to have multiple queries and
it turns out to be this.
I even placed logs in the constructor to see if it was called twice and it
was actually called twice.
Anyone experienced this ?
I used jQuery.noConflict() and the problem was solved
Does it have something to do with Wicket using $ also?
Carlo

Re: Markup Reloading
It's being transferred properly. I've noticed that when I run it on Europa tomcat server it works properly. However server is reloaded in the background everytime it is run. When I use the embedded jetty server witht eh wicket start application, I've noticed that it has something to do with the cache. When I try to switch from browser to browser, the changes effect properly. HOwever, clearing the cache of firefox for example won't do a thing. I would need to change to konqueror or something to see my changes.

Re: Harnessing Data From Components
Thanks For The Reply, Rating Panel is not a FormComponent right? So am I correct in saying that the model gets updated during the Ajax Requests ?

Harnessing Data From Components
hi everyone, I would like to ask how I could actually get data from the different components in the wicket examples... For example in the YUI selection or in the RatingPanel... What will my code look like if I have a submit button and I want to know the rating? (e.g. how many stars were pressed) I can display the components properly but I can't get data from them...

Button Command Design Pattern
Hi guys I was just wondering if this is an antipattern in wicket.
Instead of using anonymous Button classes, I created a Button Command Class
which I override.
I also created a class which indicates the button that I need.
I did this so I can be sure that I will be able to catch all the default
exceptions that exist.
Also any change in the button implementation I'll only change in one place.
Is this an anti pattern?>
I call it in my pages through this command
add(new CCTIButton("ajax-button", this, buttonCommand));
public abstract class ButtonCommand implements Serializable {
public abstract void onSubmit();
public abstract void onError();
}
public class CCTIButton extends IndicatingAjaxButton {
private ButtonCommand buttonCommand;
public CCTIButton(String id, Form form, ButtonCommand buttonCommand) {
super(id, form);
this.buttonCommand = buttonCommand;
}
@Override
protected void onSubmit(AjaxRequestTarget target, Form form) {
// TODO Auto-generated method stub
try {
buttonCommand.onSubmit();
} catch(Exception e) {
}
}
@Override
protected void onError(AjaxRequestTarget target, Form form) {
// TODO Auto-generated method stub
buttonCommand.onError();
}

Re: Versioning Problems With DataTable, Spring Hibernate
I already solved it.
I overrided the process() method of the form and caught the exception there.

Versioning Problems With DataTable, Spring Hibernate
Hi guys, I need clarity on this...
This is what my detachable model
public CCTIDetachableModel extends Loadable DetachableModel {
private String id;
private Integer version;
private Dao dao;
public Object load() {
MyObject myobj = dao.get(id);
if (version == null) {
version = myobj.getVersion();
}
else if (!myobject.getVersion().equals(version)) {
throw new MyVersionMismatchException(MyObject.class, id, version);
}
return myobj;
}
}
I use an AjaxDefaultDataTable or DefaultDataTable on my page.
So the record appears appropriately with the approprirate checkboxes
corresponding to each model.
Each checkbox is mapped to a detachable model.
Everytime I click the delete button which is an IndicatingAjaxButton,
The exception is thrown how ever I'm not able to catch the exception it on
the onSubmit() method of my
button.
The process never seems to enter the onSubmit() method of my indicating ajax
button instead it goes directly to the DetachableModel where the exception
is thrown giving me no chance to catch the exception.
How do I resolve this?

Somehow, it seems that transient objects are stored in the session.

Re: Question With Detachable Models
Thanks for replying
Yup thanks
I was debugging it and I was able to see it in the session object. meaning
that it is still stored in my object.
I changed the implementation to loading the object.
Now I changed it to loading it from a facade bean.
Thanks

Question With Detachable Models
Hi, I would like to ask this.
Are my objects still being stored in the session when I use this kind of
query.
I don't requery the objects using a detachable model.
package com.ccti.web.query;
import org.apache.wicket.model.LoadableDetachableModel;
public class QueryDetachableModel extends LoadableDetachableModel {
private transient Object instance;
public QueryDetachableModel(Object instance) {
this.instance = instance;
}
@Override
protected Object load() {
// TODO Auto-generated method stub
return instance;
}
}
Here's how my DataProvider looks like.
public class QueryDataProvider extends SortableDataProvider {
/**
*
*/
private transient QueryCommand queryCommand;
public QueryDataProvider(QueryCommand queryCommand) {
this.queryCommand = queryCommand;
}
/* (non-Javadoc)
* @see
org.apache.wicket.markup.repeater.data.IDataProvider#iterator(int,
int)
*/
public Iterator iterator(int first, int count) {
// TODO Auto-generated method stub
setQueryLimits(first, count);
return queryCommand.execute();
}
/**
* @param first
* @param count
*/
private void setQueryLimits(int first, int count) {
// can't be set anywhere else but here.
queryCommand.setPageIndex(first);
queryCommand.setPageSize(count);
}
public IModel model(Object object) {
// TODO Auto-generated method stub
return new QueryDetachableModel(object);
}
public int size() {
// TODO Auto-generated method stub
return queryCommand.queryCount();
}
