Re: Slow rendering
Hi Jürgen, I just had a quick glance at the Component and MarkupContainer classes and if I am not mistaken you should be able to override onRender() and onComponentTag() which would give you a few more measuring points and maybe more pointers on where to look further. HTH, Christian The Sanity Resort http://sanityresort.blogspot.com/ Am 16.02.2012 19:50, schrieb Jürgen Lind: Hi there, I am currently encountering a problem that I don't know how to attack... We have developed an application that uses the Tree-Component to show hierarchical data to the user. In some cases, the tree degenerates to a plain list that can be quite large. Now, if the list has around 1000 entries, the rendering phase for the tree takes approx. 1 second, which seems to be ok. For 2500 entries, the rendering time goes up to around 11 seconds and with 5000 entries, we're looking at approx. 30 seconds. Now, I would like to find out, which part of the component tree causes these huge numbers, but I have run out of ideas on how to track down these numbers. The last point I was able to measure was between onBeforeRender and onAfterRender of my subclassed LabelTree component. Any suggestions on how to instrument my application without building a custom wicket package? Kind Regards, J.
Re: Could not locate error message for component: ..
Hi, i assume the string isim 3 karakterden büyük olmalı is the error message you want to display. You have two options here, first use ValidationError#setMessage instead of addMessageKey. The later considers it's argument being a message key to be looked up from a properties file. The alternative would be to put the message into a properties file and the pass the corresponding key to addMessageKey instead of the error message itself. I would also recommend having a look at the wicket javadoc api.

Re: What is the right way to identify the second login for the same user?
I might be wrong, but this does not seem like a Wicket related problem. Here a spontaneous idea what I would try: To track sessions of a user I would try to use a database table that associates sessions with users and a boolean flag isvalid. A new session would have to create an entry in that table with isvalid set to true and in the same transaction find all existing entries for the same entries to set isvalid in those records to false. For every request a session would have to check in that table if it is still valid and if not invalidate itself and delete the record (probably best done in onBeginRequest of IRequestCycleHandler). Also when a session times out the corresponding record has to be deleted (probably best done in sessionUnbound in WebApplication). Not sure if that is the best way, but at the moment that is the only way that comes to my mind. Hopefully this gives you an idea where to start.

Re: Crossreferencing wicket internationalization
You can use a MapVariableInterpolator to replace the variable with it's
label value programmatically, e.g. resolve all nested variables using a
resolver (or Component#getString) put them as values into a map with the
variable name as key.
String label = getString(link_label);
MapString,String map = new HashMapString,String();
map.put(link_label, label);
String result =
MapVariableInterpolator.interpolate(getString(link_instructions),map);
When you use wicket:message tags you can use nested child components
(see the documentation on the message tag for further information).
In both cases you have to specify all nested variables explicitly.

Re: How to handle errors in RequestCycle.onEndRequest
Thanks for your reply Dan. My application is rather simplistic from a persistence point of view, meaning that I want all persistence actions from a request to be atomic. Of course I could move the commit calls out of the RequestCycle class which would solve this particular problem. But does that mean there is no way to properly handle an exception occuring in RequestCycle#endOfRequest to redirect to an error page or add error messages to the current page? I figured this should be doable, or could it mean that I broke something with my architecture? The Sanity Resort http://sanityresort.blogspot.com/ Am 24.09.2011 12:46, schrieb Dan Retzlaff: So you open both a session and a transaction at the beginning of a request, and commit/close them at the end? I think it's more common to only have the session last through the request, and to have transactions started/committed around DAO or controller methods. This gives your app more control over transaction boundaries and exceptions. Since this can mean lots of begin/try/commit/finally/rollback stuff, it's also common to use AOP (e.g. from Guice or Spring) to do that stuff without code for each instance.

Re: Footnote-Support
Hi again, for those who might be interessted I just wanted to let you know that I now have a working footnote support implementation. The details can be found here http://sanityresort.blogspot.com/2011/09/adding-footnote-support-to-wicket.html (another chance for shameless blog advertising ;-)). Thanks to Dan for his suggestions, though I decided to stick with my initial behavior approach. Mainly because I did not want to create a component subclass but instead enable all components with a string model object to use footnotes. I'm not sure if what I did is very wickety but at least for me it works pretty well and seems rather flexibel. Here a short summary of the features: - programmatically add a footnote to a component - programmatically process the descriptions for programmatically added components - declaratively add labels with footnotes to a markup container - declaratively add label with footnote descriptions for declaratively added footnotes - declaratively add label with footnote descriptions for programmatically added footnotes - use text or images as footnotes - use separate style definitions for each footnote and description - use freely defined wrapping tags for declaratively added footnote descriptions Any kind of feedback is as always very welcome :-) Cheers, Chris The Sanity Resort http://sanityresort.blogspot.com/ Am 19.09.2011 16:41, schrieb Dan Retzlaff: I see now. Forget the behavior approach. :) How about keeping a ListString of footnotes in the page's metadata (i.e. getPage().setMetaData(FOOTNOTES))? Create (1) a Label-like component which, in its onInitialize(), adds its contents to the list and saves the new index to be rendered as the footnote annotation, and (2) a FeedbackPanel-like component which renders the footnote content as an ordered list. You may also be able to put the footnotes into the Session's feedback data as Martin suggests, but I'm not sure how the footnote annotation and footnote content would be differentiated.

Re: Arabic characters not appearing correctly from .properties file

How to handle errors in RequestCycle.onEndRequest
Hi all, I just noticed that exceptions occuring in onEndRequest of a RequestCycle somehow do not reflect on the respone page. I am using an AjaxFallbackButton and the OSIV pattern and thus commit my database changes in onEndRequest, now if an exception occurs here I do get a log entry but I cannot get my application to display the corresponding error to the user. Adding a message to the feedback panel does not help as the message gets displayed on the following request but not the current one. I also tried using various AbortExceptions like RedirectToUrlException, RestartResponseException or AbortWithWebErrorCodeException. This did improve the situation as far as the request did get aborted but there is still no visual display of the error. Setting the ResponsePage directly and/or setting redirect to true did not change anything. This sounds like a common problem and so I guess there is an easy solution to it, but I just don't get it right now, so any pointers are welcome.

Re: Know if FileUploadField has value set before its parent form is submitted and file gets uploaded
Not sure if I completely understand what you want to do but as far as I do I guess the only way to do that is using java script. You could add a java script validation routine to the submit buttons onclick handler that aborts submission when the input field has no value. Another approach could be to add a onchange handler for the input field. If the field has a value set after a change the submit button gets enabled otherwise it can be disabled. hth, Chris The Sanity Resort http://sanityresort.blogspot.com/ Am 04.09.2011 15:47, schrieb martin.ase...@mail.bg: Hello, guys, I've got a FileUploadField as so: image1UploadField = new FileUploadField(image1_upload, new Model()); I aim to know if the field has value set even before the form gets processed and the item gets uploaded.

Create Url for Application Homepage
Hi, the method Component#urlFor(Class pageClass, PageParameters parameters) allows you to create an application relative link that could be used as dynamic links or stored in a database to be accessed later. Now I noticed that links created for the page set as the applications HomePage the result does not contain the wicket:bookmarkablePage portion. I figure this is an optimization. Those links work fine as long as the HomePage class does not change. But what if due to some refactoring you want to set another page as application HomePage? Since those links usually contain page dependent parameters the chance old bookmark links won't work or even cause an application error are pretty high. So I would like to avoid this optimization to kick in and have all links created in the same way. Does anyone know if this can be done?

Sorting Feedback Messages
Hi, I was wondering if there is a way to have feedback messages show up in certain order. Like, when you have multiple messages for the user you might want to have the most general one (e.g. success/failure) at the top and other detail messages shown below. From what I have seen so far it looks like this is not possible (at least not with 1.4.18) As a default messages are rendered in the order they have been provided, so usually you can just collect the messages you want to display and then add them at the end of your request in the desired order. But there can be circumstances where this is not feasible or at least pretty anoying. I have seen that a FeedbackPanel can be given a comparator to sort the messages but the feedback messages only provide a level field to distinguish between info, debug, errror etc. To impose a proper priority order one would need a metric orthogonal to message levels preferrably represented by a primitive (double would give the biggest freedom here). The Component class could be extended to provide additional methods like Component#info(String message, double priority) and messages which do not have a priority get assigned a default value specified in the Application class (could be 0 in the standard implementation). Would this be a useful/sensible addition? Is such a thing planned for future releases or maybe already available and I just did not see it? One workaround/hack to implement this with the current version could be to prefix all messages with a numeric string and use a Comparator to parse this string and sort accordingly. Cheers, Chris -- The Sanity Resort http://sanityresort.blogspot.com/

Include Tag Resolver
Hi all, maybe someone might find this useful. I created a tag resolver to allow include components to be used in the same way as label components with the wicket:message tag. With this resolver you can use a tag like e.g. wicket:include file=path/to/file/ to include a file into a page. It is also able to look up the file name with a property value and to interpolate variables in the included file. The complete source can be found here http://sanityresort.blogspot.com/2011/08/creating-custom-wicket-tag-resolver.html. Any comments or suggestions would be very welcome.

Re: on the fly components
Hi,
this is just a wild guess but in your code you have line that calls
item.remove(listChoice); under certain conditions and the listChoice
instance is bound to the category identifier which does not seem right
to me.
As far as I understand ListViews the associated markup block is created
for each item. If you remove the listChoice from an item then Wicket has
no object to associate the markup with. So I think you cannot remove the
choice that way.
I have a similar use case where I also add and remove objects to and
from ListViews via Ajax and it was sufficient to just remove the object
from the collection that the ListView relies on and add the wrappign
container to the ajax target.
Since the listChoice is the only thing you add to an item I figure that
could also be feasible for your case but as said before this is just a
hunch.

If you check the link sent by hariharansrc https://cwiki.apache.org/WICKET/multiple-submit-buttons.html you see an example with two submit buttons.

Re: Skip validation on nested form's form level validators
Hi, well i _could_ decouple the two forms but that would kinda break my usecase and also the layout due to the changed component hierarchy. Removing and readding the validators does not strike me as a good idea though, that would mean that the outer form would have knowledge about the internals of the inner form, which would break not only cohesion but also the law of demeter. I was thinking that since there is a defined way to let a form decide for itself if it's component's validators should be executed that there might also be a similar way to do this for form level validators. But it seems that this is not the case. So I guess I will try disabling the default form processing on the outer form and call it's component's validators manually in the onsubmit method of the corresponding button. Anyway thanks for your time. Am 11.07.2011 15:01, schrieb Andrea Del Bene: Hi, why don't simply put the inner form out of the outer one? Anyway, you could remove inner form's validators before the outer form is submitted and add them again when submit process is over (onFormSubmitted() ) Hi all, I have two forms nested within each other (wicket 1.4.17). The inner form adds data to the model of the outer form via ajax when it's button is pressed while the outer form saves the data to the database when the outer form's submit button is pressed. Both forms have validators attacehd to them and their components. and of course the inner form's validators must not be executed when the outer form is submitted. Having the inner form implement IFormVisitorParticipant and then check if the submitting button was it's own avoids the inner form's component's validators to be executed. But validators applied to the inner form directly (e.g. EqualInputValidators etc.) are still executed and in my case causing the request to die horribly because the requred data just is not there. I was looking for an elegant way to solve this but since all validate methods in the hierarchy are final I cannot hook any code into the form's on validation cycle. The method onValidate is not called (I guess that is because the form is validated as the outer form's child). All other methods that allow me to achieve the deisred behavior (like isEnabled) are too general cause side effects like disabling the form. At the moment the only way I can think of is to disable default form processing and then call the validators manually which is not very appealing to me. Is there another way how this can be done?

Hi all, I have two forms nested within each other (wicket 1.4.17). The inner form adds data to the model of the outer form via ajax when it's button is pressed while the outer form saves the data to the database when the outer form's submit button is pressed. Both forms have validators attacehd to them and their components. and of course the inner form's validators must not be executed when the outer form is submitted. Having the inner form implement IFormVisitorParticipant and then check if the submitting button was it's own avoids the inner form's component's validators to be executed. But validators applied to the inner form directly (e.g. EqualInputValidators etc.) are still executed and in my case causing the request to die horribly because the requred data just is not there. I was looking for an elegant way to solve this but since all validate methods in the hierarchy are final I cannot hook any code into the form's on validation cycle. The method onValidate is not called (I guess that is because the form is validated as the outer form's child). All other methods that allow me to achieve the deisred behavior (like isEnabled) are too general cause side effects like disabling the form. At the moment the only way I can think of is to disable default form processing and then call the validators manually which is not very appealing to me. Is there another way how this can be done?

Re: Autocomplete - get model object
Not sure if am understanding your problem correctly but how about this: The main problem is that those objects do not have ids associated with them because your service just does not use ids for the objects. But as far as i understood you have the chance to store the objects you need somewhere after you retreived them from your service, right? So can't you just assign some arbitrary ids to your objects when storing them and then use those ids within the autocomplete component? Of course this would mean that you might end up storing a lot of objects in your page/component/etc which might not be feasible..

I have an Object with address data(street, house number, city, etc) .. so I use Autocomplete to search for streets meanin .. user writes in street name and dropdown shows .. street name and city in wich street is in (meaning same streets can exists in different cities) .. so when choice is selected only street is written to the text box .. and when I wanted to use a converter same street names occur on many choices so equals method is not appropriate for checking .. cause user might have selected the 3rd choice and converter would get me an object with the first one it finds .. and ...

Custom Validator Code
Hi all, just in case this is of interest for anyone, I posted some code for custom validators that I consider useful for web applications here: http://sanityresort.blogspot.com/2011/07/some-of-my-custom-validatiors-for.html Feel free to let me know of any improvements or suggestions you have :-) Cheers, Chris - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Behaviors beforeRender broken
Hi again. Igor, thanks for your clarification, after changing isEnabled to return true the other callbacks do indeed get called. But to be honest I am still a bit confused by this fact and would be grateful for further information. The javadoc of isEnabled says that it is called when a component _is_ rendering which gave me the impression that isEnabled should be called _after_ onConfigure and beforeRender. Furthermore a component can be disabled but is still rendered (like a disabled checkbox) which in my opinion should still cause the rendering callbacks to be invoked. To my understanding that is not the case. And last but not least, even though the behavior did return false in isEnabled the links it was attached to where fully functional which a disabled component should not be as far as I know. All this leads me to the believe that my understanding of an enabled component in wicket terms s not correct. Any pointers would be greatly appreciated.
