Re: Using Wicket 6.20 give following error
Hello, just a quick observation: In 6.x version IHeaderResponse is in a different package it's under org.apache.wicket.markup.*head* so it's explained why you'd get the exception. I think this JQWicket you are using is the problem. Looks unmaintained and designed for 1.5 version(previous version than 6.x). I guess it's this one https://code.google.com/p/jqwicket/ -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Using-Wicket-6-20-give-following-error-tp4671619p4671648.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Removing jessionid
Hi,
1. you can remove the sessionid from the url and have it stored in a cookie
without any change to your app code. This is more of web container setup,
it's not really Wicket who should be handling that. With Servlet 3.0 you can
tell your web container how it should handle it in the web.xml file of your
app like
http://www.e-zest.net/blog/new-session-management-features-in-servlet-3-0/
notice the tracking-modeCOOKIE/tracking-mode option
Look into having it as HttpOnly also, it means the cookie value cannot be
read from JS so you'd want that turned also on to minimize the damage in
case of a XSS vulnerability in your site.
2. Actually Wicket already comes with session fixation protection if you
look in the Session class the method Session.replaceSession() has it
explained in the Javadoc
So say you have a LoginForm with a
public void submit() {
User user = userDao.getUser(username, password);
if(user != null) { //pardon the stupidest authorization
Session.get().replaceSession(); //we're destroying the old session
and recreating a new one - a new sessionid is returned to the user
AppSession newSession = (AppSession) Session.get();
newSession.setUser(user);
} else {
error(Wrong username/pass);
}
}

Re: Wicket FormPost via ProxyFilter
Well how are you passing the user's session between the requests? I mean your user's httpsession is stored in a cookie(not in the url), the cookie containing your user's domain usersession will not be submitted to this 3rd party in the post, and they cannot hand it over back to you. How will your application correlate the requests?

Re: Wicket Can't Find Component Error
Hi, just my 2 cents. When I usually encounter this, is because of user clicking on an old link. For example say we have a change-profile AjaxLink taking the user to profile panel. But until the server responds with the new Profile panel, it's possible for the user to click another link products in the old panel. Since the page state is different on the server and there is no change-profile link in the new ProfilePanel it's rightly stating it's not finding the component. We usually show progress and and disable the other controls with a layer on top of the controls that prevents the user from clicking other buttons until response from the previous request arrived. Just check doubleclicking on different links or buttons, or simulate an impatient user clicking away madly after he clicked on the submit button and the response is yet to have arrived. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Wicket-Can-t-Find-Component-Error-tp4665810p4665817.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

RE: Ajax timer not counting when tab doesn't have focus?
Hi,
Why so low of a timeout 50ms?
https://github.com/reiern70/antilia-bits/blob/master/client-sign-out-parent/client-sign-out/src/main/java/com/antilia/signout/InactivitySignOutPanel.js#L34
should it not be something like 5000? I don't see the point of counting down
so often. Maybe count down every 5 secs. Don't forget also to decrease the
counter accordingly.
I imagine also using console.log('time is now ...') when the timer decreases
might provide some insights on what's exactly going on.
I'd be mad as an user that something it's eating up my cpu if you'd do that
and be thankful for things like:

Re: Lots of Images slowing rendering in DataView?
Hi, I think it would be much better to use a css class for the email icon and
for any other icons that are just repeated.
Maybe another improvement would be to just use a single ajaxbehaviour for
the whole table that corresponds to a certain action like, for example in
case of a Delete, keep an itemid for the whole line and have js logic that
intercepts the clicks on the icons and call the behaviour with the line id,
something like.
AbstractDefaultAjaxBehavior itemDeleteBehavior = new
AbstractDefaultAjaxBehavior() {
@Override
protected void respond(AjaxRequestTarget target) {
String id =
RequestCycle.get().getRequest().getRequestParameters().
getParameterValue(id).toString();
//do delete logic with item ID. Just be careful that
malicious users exploit it by passing items of other users.
}
@Override
protected void updateAjaxAttributes(AjaxRequestAttributes
attributes) {
super.updateAjaxAttributes(attributes);
attributes.getDynamicExtraParameters().add(return { 'id':
itemid });
}
@Override
public void renderHead(Component component, IHeaderResponse
response) {
AppendingStringBuffer js = new AppendingStringBuffer();
js.append(function deleteItem(itemid)
{).append(getCallbackScript()).append(});
response.render(JavaScriptHeaderItem.forScript(js,
deleteItem));
}
};
add(itemDeleteBehavior);
then on the clientside js have something like:
$(.actions_delete).click(function(event){
deleteItem($(this).prop(id_to_remove));
});
This way you'd keep the page size sent to the client small(there would not
be a big url for each icon link). Smaller pagesize, means faster transfer
and less data for the browser to parse and render. You get a bonus also in
simple component hierarchy because you don't even need to have a java
component for the links.
The same for other common behaviours like edit, etc.
Hope it helps.

Re: Tracking performance issues on requests best practices
Well I've switched on to AspectJ load time weaving and was able to intercept calls on also the wicket Components methods. I've tested locally to see where are the missing numbers. Seemed not much time was spent in onInitialize() afterall, the cause by the fact that even if the Services layer was intercepted, I did not think of the OpenEntityManagerInViewFilter which caused DB hits that were not going through the Service layer and thus not counted. 2. I was counting also the first hit of the first page which meant getMarkup calls for the components. That markup is then cached on subsequent calls but when called it does take it's toll. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Tracking-performance-issues-on-requests-best-practices-tp4657676p4657706.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Tracking performance issues on requests best practices
Hello guys, I'm trying to have a finer look at what is taking time on the serverside in our application. What I have so far is that I'm using Spring AOP to track down calls to all the methods and time to the Services layer. PS: I'm using JETM http://jetm.void.fm/ (it may be old, but is simple and give pretty much what you need). 2. I've collected the time for the whole request to process in a AbstractRequestCycleListener onBeginRequest, onEndRequest so as to see a sum of the total time spent on a particular usecase. What I've expected to find is that most of the resulting time would be spent in the services layer and pretty much summed up to be near the request time on the requestcyclelistener. Practical data shows however otherwise, with the sum of the service time not even close to the total of the request time. 3. So I've fine tuned the result to also show the rendering time for the components taking as example RenderPerformanceListener which measure the time between component onBeforeRender and onAfterRender. It's pretty nice to see in jetm hierarchycal component-services call, however it still not nearly close to the whole request time. I'm still looking and seeing that there is some logic also on some component's constructors and also onInitialize() methods that I see no easy way to measure them. IComponentInitializationListener seems to only trigger after initialization, I see no easy way to mark the start time of the onInitialize() and collect the time in the listener. So I'm asking if anyone got an idea, or I'm interested what you guys usually do to track down any performance issues in the app. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Tracking-performance-issues-on-requests-best-practices-tp4657676.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Deploy on production: optimization tip tricks
Hi Oscar, Probably nobody responded because this is not a simple topic but with many implications and turns. There are many optimizations that can be done not necessarily related to wicket. I'd recomend http://stevesouders.com/ blog, http://www.bookofspeed.com/ , http://www.guypo.com/ But ok I'll play along and add my 2 cents: 1. Setting Caching headers on the web response is for certain something that you'd want to do. Set a long expire date for JS and CSS file like months even 1year. But you'd also want the users to receive the latest css and JS files you make with a new release. So it's good to mix up the resource name with some kind of version token(I use the app version nr in the css/js files name something like link rel=stylesheet type=text/css href=/2.14/css/site.css /). Also most important optimizations that give the user the impression of speed are related to loading the JS files. While JS files are being downloaded the PAGE RENDERING is STOPPED. So it's a good idea to put them at the page's bottom and using the css and html to render the page in an usable(nice looking) state and then, while the user is reading and figuring out the content, the JS enhancements like sliding menus etc are loading in the background. Otherwise keeping the JS at the top results in the so called WhitePageOfDeath in which the user sees a blank page while the header JS files are being downloaded. You can achieve the same thing as putting the JS at the page bottom but while keeping the JS files at the head with the defer attribute easily like . That means the rendering will not be blocked but the JS will execute on DomReady event. 2. Minification and merging JS files into one: A. Most today's browsers are limited to making at most 6 parallel requests to a certain domain. So you don't want to have more js files merged into a single one so you don't wait for another wave of free connections. There is also the RoundTripTime overhead associated with making a new call to the server. B. The the bigger a text file is, the better it's compression ratio will be. So you'd get some benefit from merging all the js files into one and the gzip compression will be greater and also the minification gain. I recommend the *wro4j* project as it has lots of minification plugins. Unfortunately Wicket's component nature where every component can contribute it's own separate JS file makes it harder to have a single big minified JS file for all the page. 3. Using CDNs have the benefit of lower latency and also introducing another domain and thus increasing those 6 max nr of connections. Using some famous CDN like you did for JQuery also increases the probability of user already having Jquery in the cache from another site that he visited before(that's why I'm a fan of not also including the JQuery library in a minified package of all your site's JS files). Using asynchronous loading for 3rd party scripts like g+, facebook, ga are mandatory also these days. 4. Caching before the web server layer - using a caching proxy like Varnish or Apache/Nginx with a caching module to save maybe DB generated image resources maybe can be a good idea also. The topic is far far from being exhausted so I think that's the reason why nobody is playing along with responding. Personally I'm curios if an enhancement of providing Transfer-Encoding: chunked and keeping the JS resources in the head with the defer attribute(so the browser quickly receives the header and can begin the download of JS files) while a slow DB prevents us from returning the full html. But I'm afraid it might be a mess with not really huge gains in performance and wicket by it's component nature means we don't know the required js resources in the page's head until all the components have been added to the page and got a chance to contribute there needed resources. I'm also curious what the future holds in terms of the SPDY protocol since optimizing for it and might go against today's best practicies of splitting resources across many domains. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Deploy-on-production-optimization-tip-tricks-tp4653774p4653928.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
ComponentNotFound exception question
Hi guys, I'm asking for an opinion on how to approach the following:
Wicket 1.5.7, browser Chrome, Firefox.
I have a FormTestPanel with
TextField and AjaxFormComponentUpdatingBehavior attached:
AjaxFormComponentUpdatingBehavior formUpdate = new
AjaxFormComponentUpdatingBehavior(onblur) {
@Override
protected void onUpdate(AjaxRequestTarget target) {
//do nothing just want to update the textfield model on
leaving it
}
The Form also has an AjaxButton:
AjaxButton btnSend = new AjaxButton(sendMessage) {
@Override
protected void onSubmit(AjaxRequestTarget target, Form? form)
{
//replace through ajax FormTestPanel with Empty panel
let's say
}
}
My view on this was that the flow would be to queue events in this order:
Blur
Submit
somehow it gets to
Submit
Blur
This causes a ComponentNotFoundException: Could not find component
'content-panel:form:textMessage'.
Shouldn't page versioning help with ComponentNotFound in this case? Sure
the component hierarchy changed after the form submit but that blur event
should have the older version of the page which had a different component
hierarchy?
I tried putting a Channel 0 type Drop on both behavior and AjaxButton:
@Override
protected AjaxChannel getChannel() {
return new AjaxChannel(0, AjaxChannel.Type.DROP);
}
but it doesn't seem to cancel any of them, anyway I wouldn't have expected
this to work as it would have probably canceled the submit button event but
it was reminiscent of the times when I thought the blur event gets triggered
twice.
My current solution was so far to setResponsePage which I think might work
as it will clearly target another version but I didn't want to have to give
up on the SinglePage setup.
Any other idea how I can handle this?

I think Martin was pretty explicit with the fact that you could use as endpoint an AbstractResource or even a plain servlet as your data source url, you don't need explicitly an ajax behaviour(although just setting the stateless hint to true on the ajaxbehaviour might work without any problems). You can add http://thewicketevangelist.blogspot.de/2011/12/marrying-wicket-and-jquery-ui.html but any implementation would work, and use the url of your mountResource(IResource) on where you return a JSON based on the query parameters. You don't even need to add the ajax behaviour to contribute the autocomplete JS(which is a static string if the data url is not dynamic) to your panel so your page is stateless. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Making-Autocomplete-Form-Stateless-tp4455817p4649853.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

On the other hand, the wicket session can exist in a temporary state for the duration of the request and not have a HttpSession created.

Re: Unnecessary 302 redirects in Wicket 1.5
Hi Lim,
What about using an AbstractResource instead for serving the xml.
You can do something like:
@Override
protected ResourceResponse newResourceResponse(Attributes attributes) {
final ResourceResponse response = new ResourceResponse();
PageParameters requestParams = attributes.getParameters();
response.setLastModified(Time.now());
response.disableCaching();
response.setContentType(text/xml);
response.setTextEncoding(UTF-8);
response.setWriteCallback(new WriteCallback() {
@Override
public void writeData(final Attributes attributes) {
attributes.getResponse().write(xml..);
}
});
response.setContentDisposition(ContentDisposition.INLINE);
return response.
}
And you have all the benefits wicket like @SpringBean available, access to
wicket session, etc.

Thanks. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/1-5-SNAPSHOT-build-repository-tp3565884p3567695.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Wicket in Action - 1.4 pending release
By the way Wicket is growing and changing i thought that the book would never been finished as one chapter was probably done, another would have to be refactored to keep it up to date with the API. Actually the only time when i had to rewrite code for switching to another version was from 1.2 to 1.3 and the migration guide made that quite painless. Congratulations on finishing, although the MEAP is no good for me, as Romania seems not to be a valid country(too many of us getting rich from buying pdf books with fake cards i guess or something) so will need to wait for Amazon paper version :(. Eelco Hillenius wrote: I'm just curious if the move to 1.4 will have an impact on Wicket in Action. Hi Ned, I'm afraid not, because we are right now finalizing the book and we still have to start working on 1.4. I would also mean weeks of extra work for us, and after more than 2 years of writing, we've had it :-) The good thing is that it shouldn't make a big difference to start with; you should be able to use 1.4 without the generics just fine if you just ignore the compiler warnings. Maybe we'll bring out an extension to the book sometime around when 1.4 becomes final. But no promises. :-) Eelco - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- View this message in context: http://www.nabble.com/Wicket-in-Action---1.4-pending-release-tp16228144p16361218.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]
Re: Disabling serialization/storage of pages in session?
Why is everybody pointing out not to have database data inside the page? Many times retrieving the data from the database could be the slowest thing and having that sort of cache is one nice thing in my opinion. Is it not much better to have data in the session? I understand that it will be a negative point in clustering for session replication, but that might not be such a drawback. The state could be replicated to the other server asyncroniously after the request was presented back to the user so he sees no degradation in performance, or better use sticky load balance and not have session replication. Also you might need to sacrifice the availability of the back button, although by keeping multiple versions of the page that can be avoided? Are there other negatives?.

Re: Disabling serialization/storage of pages in session?
Most database expensive operations come from the result of stored procedures(my current experience at least). A cache solution can be implemented by caching the method results with spring(in case of using spring) but is a heavy(difficult) thing to maintain that cache per user - http session is a nice and easy storage for that-. Eelco Hillenius wrote: You should use a second level cache to cache objects and queries from your database; and that's not Wicket's job, Wicket is a Web framework. For example, use Hibernate + ehcache. Yep. That way you'll avoid redundancy in caching, and have caching regardless of whatever UI framework you're using. and using e.g. ehcache can do things for you like limit the RAM cache and overflow to disk. Etc.

Re: Disabling serialization/storage of pages in session?
I'm not for not considerate caching outside the web layer or a naive aproach to cache everything even if that object changes 10 times a sec. I am just saying that it may be ok in some cases to keep state on some objects and not have detachable models. I'm not saying keep all in session and pay no considerations to separation of concerns. A nice design surelly is where the cache stands beetween the web and the database layer, but we may have the case where we use stored procedures intensively and the result may take a long time to return but that result may well be not be heavy(i guess that can be the case with stored procedures). We always have to think of the impact of presenting stale data. Johan Compagner wrote: Also caching data inside a session and having those object over multiply request gives in hibernate always errors like LazyInitalizationException or Transient/StaleObjectException Holding on to data in sessions is really a bad idea because you dont know when they come back if you have a session time out of a few hours, and people open pages and then do nothing for 15-30minutes then a huge page is kept in memory all the time. So if you keep growing users then you will hit memory problems very soon. Also if you constantly cache objects are those objects not changing between request by others? How do avoid state objects? User A changed an object and tells that to User B that wants to work with it. Then User B hits refresh 10 times but still sees the old value.. johan On Nov 9, 2007 9:13 AM, serban.balamaci [EMAIL PROTECTED] wrote: Why is everybody pointing out not to have database data inside the page?

Re: Popup parent comunication
Wel i use wicket 1.2.6
Sadly it seems to be a browser compatibility issue. Default I use firefox
but tried it now in IE 6 and IE7 and in firefox there is the problem and in
IE it works as expected.
Hmm...

Re: Why dioes this error occur?
Hi. Well in my case this error apeared when the user clicked on a link that was directing the user to the next page, and while the user did not wait for the other page to load, or he thought that he did not press the mouse button and he clicked again. The server saw that the component(link) was no longer in the the new page and therefore the nullpointer.

The popup window is a window in which new records can be added, but i need a combo in the parent page to reflect and contain also the new choice added in the popup. 1. Reloading the whole parent page at popup close link pressed i would take as the last resolve because the user may have introduced data in the controls that would get lost in the reloading process. I could get around this by adding a submit behaviour to the link and save in session the values inserted till that moment and rehidrate the model with values from the session instead of the database, and so obtain the state that the page was in before the popup was opened, but i'm wondering if there is not a cleaner solution for this. 2. I also tried(didn't think this would work:) but had to try) to pass the combo to the popup page and tried to update through the pressing of an ajaxlink the combo. It said it could not find the markup id for the combo(expected since it tried in the popup and not in the parent) so i guess that this approach could be made valid if the ajax callback would be directed at the parent page instead of the popup - i do not know how to do this. 3. Another option I am considering is calling a self.opener.function in which i would have javascript code for the ajax update of the combo in the parent. What code that is doing the ajax update i still do not know where to find- maybe on the onselectionchange behaviour would be the way to find out, or if it breaks something in the way wicket is working. Anybody has any pointers of what would be the nice way to implement, comments, or other ways to tackle the problem?
