Re: Behaviour adding to Component body
On 7/30/07, Jan Kriesten [EMAIL PROTECTED] wrote: Hi Igor, i really dont think oncomponenttagbody() belongs in behaviors. this should be done without a behavior by subclassing the component and overriding oncomponenttagbody() there. that said you can still hack it by using AbstractTransformerBehavior and some string manipulation code. I don't think this should belong in a subclass. IMHO manipulating attributes for a certain type of object should be handled by simply adding a Behaviour. yes i agree 100%. but, you are not manipulating attributes, you are generating additional markup int component's body. SWF's are only one example. Other Objects (QuickTime, Real, WMV) have other Attributes and parameter needs which is where Behaviours do what they do best: manipulating them. The Problem is, that Objects aren't handled Browser independend. So it's enough for FF Co. to have a 'data'-Attribute for the SWF, whereas IE needs the param name=movie... and no 'data' to have the movie streamed. ATM it looks like this: WebMarkupContainer swf = new WebMarkupContainer( swf ); ResourceReference resRef = new ResourceReference( HeaderPanel.class, res/mymovie.swf ); swf.add( new FlashAttributes( urlFor( resRef ).toString(), 700, 70 ) ); add( swf ); It really looks messy if you subclass it and take into account the 20 other parameters you could add the Object... well the logic has to go somewhere so just do SwfObject object=new SwfObject(swf, resRef, 700, 70); instead of putting it into a behavior put it into a custom webmarkupcontainer subclass instead. -igor Best regards, --- Jan. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I see that DownloadLink can be used to stream a File.
What I want to do is use DownLoadLink to redirect to an external URL

I can't use ExternalLink as the external URL's location is not pre
determined,
also the external URL's location lookup is a costly so I don't want to do
it unless
the User clicks on a link.
So in my case I do some thing like
class DownloadUrlLink {
onClick() {
URL externalUrl = getExternalURL(); //this is a costly operation, so I
don't want to do it unless user clicks the Download link.
getRequestCycle().setRequestTarget(new RedirectRequestTarget(url.toString

The URL points to a rather large gzipped XML file about 11MB in size.
But instead of popping up a File Save dialog, the browser starts to
display the XML file.
and CPU usage jumps up to 100%, on account of the file being this large.
Is there a way to force the browser to pop up a FileSave dialog when using
RedirectRequestTarget

Re: Motivation for having setRequired()
the whole refactor started because validators were doing a lot of repeitive
stuff.
for example lets say you have a textfield for a purchase quantity. you add
three validators to it, requred, min1) and checkinventory.
min(1) = { if (input==null) return; int i=typeconvertinput(); if (i1)
error(); }
checkinventory() = { if (input==null) return; int i=typeconvert(); if
(igetavailable()) error(); }
what do we notice...
both validators have input==null check because they will run whether or not
field is required or not. both validators have to perform typeconversion -
which is potentially an expensive operation.
so lets refactor type conversion into the formcomponent. great, but the
problem is we dont know if we have to convert a or not. so we also factor
out the required check.
the nice thing about it is that now our validators look like this
min(1) = { if (i1) error(); }
checkinventory() = { if (igetavailable()) error(); }
so now not every validator has to check for null, and type conversion is
only performed/checked once and in a single place.

// Constructor for Form

email.Required=Enter your email
subject.Requried=Enter the subject
Or are the two ways you described in your last message the only ways to
possibly resolve customised messages (unless, I suppose, if I create my

Essentially, I would like to have finer-grained control over my

So:
formid.email.Required = blah
requires me to rewrite them for every page, but
Required = Enter your ${label}

Re: Authentication in Webapp and Wicket documentation...
On 8/8/07, Alexander Schatten [EMAIL PROTECTED] wrote:
Greetings to all Wicket experts
I try to get Wicket running for some rather simple web-application.
First (no offense, but have to say that), Wicket has the worst
documentation of an apparently good open source project I have seen in a
long time; and this is really a pity, because it seems, that if one
would know how to do it, many things can be performed quite easily.
have you seen the wiki?
Now to my current issue: I want to add a loginpage to my project and
protect some of the pages.
My first thought was to make a base class (worked) and somehow hook into
the lifecycle, check if the user is checked in (MySessio works) but this
is not running at all. lot of redirection errors, incoherent
documentation and so on. e.g.:
have you started by checking out Signin, Signin2, Authentication,
Authorization examples in wicket-examples?
Javadoc 1.3 of Page talks about checkAccess() method... however, this
methdod can be found nowhere.
yes the javadoc is outdated, fixed
Now I check the mailing list archive, only useful thing I find is a
posting from 9.2.2006 suggesting:
protected void init()
{
getSecuritySettings().setAuthorizationStrategy(new
IAuthorizationStrategy()
{
public boolean authorizeAction(...) ...
public boolean authorizeInstantiation(...) ...
}
starting with 1.2. Well, this interface is still here, but these methods
are not available any longer.
There is no documentation about this strategy I could find and the
Javadoc (which is btw. not linked from the wicket website, and just this
made me search for an hour) is very unconclusive.
we are working on linking the javadoc...you do know wicket is a maven
project right? so there is of course javadoc in the maven repo:
http://repo1.maven.org/maven2/org/apache/wicket/wicket/1.3.0-beta2/
further, since it is open source simply attach the sources to your ide and
you are set.
if you are using maven2 and eclipse add the wicket dep to your pom and do
mvn eclipse:eclipse -DdownloadSources=true - and you are all set.
now that you have found IAuthorizationStrategy have you even looked at it?
for example have you pulled up its class hieararchy to see an example
implementation? for example when i do it it leads me directly to
SimplePageAuthorizationStrategy - which will probably get you started - even
if you havent looked at the 4 examples i have mentioned.
btw. another thing: when the documentation of a project is so bad, at
least the javadoc should be accessible: I tried to build mvn site with
wicket and got the error that you use a special template or somthing and
it does not build, and this template is apparently not in the repository
ARRRGGHHH.
yes working on that too. maven2 site generation is a pita and eats up a lot
of time to get working.
sorry, but Wicket experience was far away from beeing pleasent. I am
quite willing to check several sources, but this here is really bad.
have you gotten the Pro Wicket book?
outdated information is not easy to distinguish from actual
documentation, the reference to the component doc is nice, but component
doc very incomplete and so on...
you are more then welcome to help out.
Wicket seems to be a quite productive and powerful framework (one of the
best I have seen so far, at least so it seems), but getting into it is a
damn frustrating experience, I can tell you...
you are meant to look at examples first. they cover all the basic usecases.
learn-by-example has been our philosophy so far.
(I did not even know where to start. happyily there is a maven archetype
at the Jetty website which was helpful.)
So, sorry for that outburst, but I was so frustrated...
no problem

Hello all, first time post.
I used Wicket 0.9 for a large project awhile back. We have continued to
upgrade Wicket with every new release, and we currently sit at 1.2.6. I
haven't done much maintenance on my project because every Wicket upgrade
has
been smooth.
One feature Wicket didn't have back then was a SubmitLink, so I built my
own.
Now with Wicket 1.2.6, my SubmitLink doesn't work but Wicket's SubmitLink
works. Let me explain;
I have a dynamic page which contains a form which may contain listviews
with listviews with listviews (up to 3 deep). Users can add and delete
listviews at any depth and modify data in the listviews. The add and
delete
links in each listview are SubmitLinks so data isn't lost when the page
reloads. Here is the problem;
Say I have listviews 1, 2 and 3. When I delete listview 1 with my
SubmitLink
and the page returns, listview 1 and 2 are still present, listview 3 is
gone.
The database says listview 1 is deleted. If I leave the page and come back
(the model is reloaded), listview 1 is deleted and listview 2 and 3 are
displayed. When I delete listview 1 with Wicket's SubmitLink and the page
returns, listview 1 is gone and listview 2 and 3 are present.
So, to test I coppied the source of Wicket's SubmitLink into my own
SubmitLink
class and tried it out. The same problem explained above occurs, even
though
the onclick output of my SubmitLink is exactly the same as the onclick
output
of Wicket's submit link (the rest of the html is exactly the same too).
Strange.
I would use Wicket's SubmitLink, except I need a confirmation dialog to
popup
to confirm a user's delete request.
So, does anyone know how to easily modify Wicket's SubmitLink javascript
so I
can have my confirmation dialog? I could override getOnClickScript() and
pass
in a bunch of javascript, but I would rather somehow grab the onclick
javascript from SubmitLink and append the confirm.
Or..., any other ideas?
Thanks for any help,
Darren H.

Re: sharing a context menu across components
what i am suggesting is this: if you only want to have a single instance of behavior per table, yet have onclick react per row you need to have some javascript on the clientside that can tell what row is clicked by appending something meaningful to the behavior's callback url. you do not need this when you use an instance of behavior per row - because wicket already builds the unique name that can identify that row/behavior for you - which is the component path of the component that contains the behavior. -igor On 8/13/07, Kirk Israel [EMAIL PROTECTED] wrote: I guess I'm not understanding what you're suggesting. I've added a ContextMenuBehavior to the dataTableComponent row. Inside the ContextMenuComponent that is also on the page, there is an AjaxLink anonymous inner class. that overrides onClick(AjaxRequestTarget pRequestTarget) But the result of getPath() always has the same problem, even when I do ContextMenuComponent.this.getPath(). The Behavior isn't in the path, because it's not part of the nesting hierarchy. It stands outside and connects, and as you can see below the path says dataTableComponent:campaignContextMenuComponent - the fact that behaviors have been added to the dataTableComponent's rows doesn't matter to the path, at least in the straight forward way I've made the contextMenuComponent. (Just to make sure I wasn't missing something obvious, I tried adding the contextMenuComponent to the Behavior rather than to the dataTableComponent, but of course there is no .add(Component) for behaviors, so the concept didn't make sense.. you can add a behavior to a component but not vice versa) What am I not getting here? Is there some other kind of special menu item class I need to use that would capture the path of the behavior that invoked it?( Because right now it's just a component that happens to be showing up and relocated because of the behavior i added to the rowitem.)

Re: Dynamic AJAX Tabs
hmm, its still pretty difficult to tell what is going on.
how about a quickstart that reproduces the problem.
you want to have an ajax tabbed panel where the number of tabs is variable,
so when you recalculate the number of tabs why not simply replace the
tabbedpanel with a new instance and add the new instance to the ajax target.

If I try to access directly either one of:

However, if I first access cxt1, then later try to access:
www.example.com/cxt2{/}
Wicket is forwarding me back to:
www.example.com/cxt1
And vice-versa when I first access cxt2 and later try to access cxt1
without a path.
Also, none of my links are working as expected. Once cxt1 is cached, all
my links now point to that context, which messes up what I'm trying to

Is this a bug? If so, where should I look to fix this?

Re: Wicket vs. ZK
On 8/15/07, juliez [EMAIL PROTECTED] wrote: First, thanks for the reply! 2. AJAX components (Wicket vs. ZK) you do not implement features like drag and drop or datepicker in wicket, instead you wrap javascript libraries that implement those features with wicket components. I am actually confused at how many ways Wicket supports AJAX. The classes in wicket.ajax packages are used for AJAX behaviors. I supposed these classes are for common AJAX behaviors. wicket has an excellent native ajax support. it allows you to perform partial page renders where only one or more components on the page are updated. see wicketstuff.org/wicket13 for examples under ajax. it also has common ajax handlers - so you dont have to reinvent the wheel - such as form component update, ajax form submit, self updating timers, etc. It seems they are different from wrapping JavaScript - correct me if I am wrong. javascript is not the same as ajax. take drag and drop - that has very little to do with ajax except maybe for notification that x has been dropped into y. take datepicker, that has no ajax in it at all, its just javascript that draws a calendar and puts a selected date into a textfield. Then my questions are 1) what is the standard way to add AJAX with Wicket: first looking for existing components (including the components in WicketStuff), then if not found, wrap JavaScript? if you have some ajax need that wicket doesnt natively provide and that is existent in some 3rd party js lib then you can easily write wicket wrappers for it. the nice thing about it is that you only have to do it once, and from that point on you dont need to worry about javascript, just use your java classes. for example there is wicketstuff-animator project that wraps animator.js in a set of wicket components. you can add animations without known the details of the animator.js lib. 2) I read the attached file and googled more for the instruction on how to wrap JavaScript. Found one here (http://cwiki.apache.org/WICKET/adding-dynamic-field-prompts-or-hints.html ). I am wondering if there are instructions on how to do it in a general way. there is no general way, you simply write components that hook into the javascript. 3. Target application (Wicket) like you say, wicket is component oriented. it doesnt really care how you build your app: many pages or a single page. at my day time job we have an app that is mostly a single page with a lot of component replacement. works just fine. Still not sure, if a page includes many replacement, how to keep the method/class short yet support those changes? you dont define the combination of all possible replacements at the same time. wicket is dynamic, at any point in time a component can replace itself or other components with something else that was just instantiated. also because components are encapsulated they can perform replacements inside themselves as well. wicket is not page-centric. -igor

After migrating from wicket-1.2.6 to wicket-1.3.0-beta2 I had the
following
problem:
application throws ConversionException when trying to convert a
null
value
of the Textfield wich is disabled on the clientside.
I've take a look on the convert() method of the FormComponent
class
and
noticed the difference from the 1.2.x branch which may cause the
issue:
This snippet of code is from 1.3.0-beta2
[CODE]
if (typeName == null) {
//string conversion code
} else {
//type conversion code
}
[/CODE]
This snippet of code is from 1.2.6
[CODE]
if (type == null) {
//string conversion code
} else if (!Strings.isEmpty(getInput())) {
//type conversion code
}
[/CODE]
As you can see, in the 1.3.0-beta2 version, the conversion does
not
check
if
the getInput() is an empty string before performing type
conversion.
I
wonder if it is a bug, or it is something that I missed?
Thank you!

Re: Is there something like ValidationDelegates in Wicket?

Re: url mapping and wizards
this is not how wicket works. bookmarkable urls are entry points, but once you change the state of the page you have to keep track of that instance somehow - that is what :12: is in that url - a wicket page id. so once you change the state of any page it is no longer bookmarkable and thus cannot have a ncie url. -igor On 8/16/07, wicket user [EMAIL PROTECTED] wrote: Hi, I've just started using Wicket and I've managed to mount pages so that the urls are cleaned up but for the life of me I can't seem to get it to work with Wizard pages.

Re: Is there something like ValidationDelegates in Wicket?
my border handles multiple formcomponetns if they are meant to be grouped. for example you can add 3 textfields and it will create labels like: city/state/zip [text1][text2][text3] errors for text1/text2/text3 i have a utility method in my Form subclass addWithBorder(String borderid, FormComponent... fcs) so my code usually looks like: addWithBorder(nameborder, new TextField(name).setRequired(true).setLabel(new ResourceModel(user.name )); and in markup: div wicket:id=nameborderinput type=text wicket:id=name//div the border will then generate tdlabel for=namename/label/tdtdinput type=text id=name ... / [any errors]/td unfortunately i can post the code for it, but it isnt very complicated -igor On 8/17/07, Onno Scheffers [EMAIL PROTECTED] wrote: Hi Igor, does this mean that you wrote a Border component that handles multiple formcomponents at once?

you can load that .properties file yourself from inside your validator
you can put these properties into application-scoped .properties file.
you can also add an rfe into our jira to allow validators to have their own

Re: generic validator questions
im not sure exactly what your usecase is.
we have something that is kind of similar, namely new TextField(number,
Integer.class); which would type convert the entered string into an Integer
and error out if the conversion could not be performed.
but i dont think this is the exact match to whatever it is you are trying to
achieve.

Hi Igor,
First thing, thanks, your hints gave me the direction and I solved the
issue... I like the approach 'Classname.Key' and I think it's right for
this category of generic validators as are those in 'validator'
package.
It was just a question of overriding one method:
@Override
public void error (final IValidatable validatable, final String
resourceKey) {
super.error(validatable, resourceKey() + . + resourceKey);
}
and everything worked like a charm ;-)
What do you think of adding this validator in trunk ?
Cheers,

Re: Loading global resources in test?
wicket tester uses a mock web application - not yours - so it cannot load
those properties. i think in 1.3 we refactored it to support custom
application subclasses. i think as far as you can make it work in 1.2.6 is
to change resource settings not to throw exceptions on not-found-resources

If FeedbackPanel would work that way, we'd have Matt's behavior out-of-the-box, which imho is a lot better than the current way that feedbackmessages just print out any messages regarless whether they already were consumed by another feedback panel.

As I said in my previous post, I do my database queries in this way: ResultSet rs = cs.executeQuery(); In fact, later I'll use a code generator to ease the task, but let's assume for simplicity that I get the result in a java.sql.ResultSet. But, as stated in the Wicket Extension Javadoc, I must create the DataTable instances in this way: DataTable table = new DataTable(datatable, columns, new UserProvider(), 10); Specifically, the third parameter must implement wicket.markup.repeater.data.IDataProvider; which ResultSet doesn't implement, so I must provide for a means to overcome this. I didn't intended to mean that ResultSets are more generic that DataProviders.

I'm concerned about how well this will go in regard of sortable and pageable tables. Perhaps there is a mean to do all that already in the Wicket library, but I havent found it yet.

Re: POJO Adapter in Wicket
i would use the pojos directly and put the presentation stuff into the model -igor On 8/23/07, Vincenzo Vitale [EMAIL PROTECTED] wrote: Hi All, I'm using Wicket (1.3.0 beta2), Hibernate and Spring. In my Wicket project for each POJO of my business model I created an Adapter maintaining the original object and having methods for the presentation layer (like getCompleteName()); I have not created a delegate getter or setter for all the properties of the target so in my wicket java code I simply bind the target properties with a name I choose. For example: final ApiAccountAdapter account = (ApiAccountAdapter) model.getObject(); BoundCompoundPropertyModel accountModel = new BoundCompoundPropertyModel(account); TextField contactNameField = new TextField(contactName); accountModel.bind(contactNameField, target.contactName); I use cascades with Hibernate to create/update my objects so the unique problems with the adapters approach is that I always want to use Adapters in the presentation projects and I always want to navigate my objects starting from the main object I'm using. So for example if I'm editing a parent object with a child list, in Wicket I need to create a ParentAdapter with a method like ListChildAdapter getChildsList(); returning the List of adapters and I need to manually construct this method. If a child has also relations with other objects (directly or worst into Collections) the problem became rapidly really complex. Have you some suggestion on how to face in a better way the problem? My main requirements are: - I don't want to modify the POJOs adding presentation getters. - I want to use the dot notation in Wicket to easily access what I need: directly the pojo properties or some adapter (or whatever) with more complex getters. - When I have an input field in a page, representing a simple property in the main object or in some child object (like a property of a specific element of the child list) I don't want to manually map this field with the property of the object I want to be persisted. This work fine using adapters and mapping always an input field with target.property or a list with target.getListAdapter and then mapping the input fields in the list also with target.property.

Well, I guess, we can't use a servlet, because wicket is registered

wicket is a filter, so even though it is mapped to /* it will let

Re: Component Factory and code against interface
the ui layer is generally not portable. if you start building your own abstraction to make it portable you will end up with a pretty big mess because you will be working against whatever framework you are using and eventually that abstraction will turn into a framework itself. -igor On 8/24/07, Sam Hough [EMAIL PROTECTED] wrote: Many thanks Igor, that sounds like a very pragmatic approach. I was thinking about all sorts of horrible kludges like re-rendering the whole page and seeing how elements changed or hooking into the serialisation. Taken away another reason to do my over complicated solution ;) Am I worrying over nothing that developers might get carried away using vast number of components and fiddling with attributes that will make the application difficult to test and maybe one day port? Restricting the set of components can presumably end up with a more consistent UI...

Re: Newbie questions
On 8/24/07, Alex Shneyderman [EMAIL PROTECTED] wrote: I wonder if there is any documentation as to how the rendering process works How do I go from Component graph - html associated with the page? the basic answer is that wicket traverses the component graph and calls various render methods on the components, which then output the markup. And what is the model's role there. i assume you are referring to component.get/setmodel(). this is a default model slot that all components have. its use varies per component. for example label uses the default model slot to get the string it will replace its body with. listview uses it to retrieve a list of items it will use to populate itself. link doesnt use it at all - allowing the user to put their own model into it which is then easy to retrieve inside the onclick event. as your questions get more specific so will the answers :) I have been reading and re-reading the getting started manual, unfortunately it is an extremely incomplete document, so it is of a very limited use, although I appreciate the intention. we depend on our users to make it better.

Re: Alternative to Wicket data binding
On 8/25/07, Eelco Hillenius [EMAIL PROTECTED] wrote: So you write a class with a certain member, but as you don't want people to directly access that member, you don't provide an mutator method. Someone else takes a look at your class and decides to directly access the member using property model regardles. I know people can do it with introspection anyway, but it arguably breaches encapsulation. my point is only that if people wanted to do this they could with or without the propertymodel. and if you really dont like it just go ahead and install a security manater. If you have a component/ page with members and in that component/ page you link a property model to it, I think it is fair to say you'd like to access the property as an implementation detail. But for regular domain objects, I don't see why normal rules of encapsulation wouldn't apply. what if i have a non-public top level class in my ui package sitting next to the component that uses it as a propertymodel object? all im saying is that narrowing it down to a direct property of a component is too narrow. in fact it just makes it more confusing when it does and does not work. Anyway, we built the damn thing so we know about it, though I - as a member of the dev team - didn't even know about this 'feature' until recently, neither did Martijn give this any special mention in his chapter on models so far. Also, this is the second time the topic comes up, so I don't think it is as obvious or intuitive as you are suggesting. yes it is the second time this topic comes up out of how many of thousands of users there are i dont know. i think this feature is very convenient. it is not something you can toggle on and off because 3rd party components might be written with this in mind. so i would say keep it, end of story. but that is just me. -igor Eelco - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

If you want to avoid clutter (i.e. writing getters and setters) and you don't care about breaking encapsulation, why not do it the Java-way? Saying that you don't want to expose your members for normal Java programming, but do want to expose those members when using a property model strikes me as having a double standard. first of all the bean spec is _not_ the java way. it is just a spec, widely adopted though it is - just like jsf. second of all we _are_ doing it the java way. reflection has access to private fields and property model uses reflection, that is the java way. and third of all i think this _helps_ preserve encapsulation not break it. this whole argument started because someone _looked_ at the javadoc and said oh crap this can access private fields, oh no this is so anti java!, a purely theoretical concern, that will probably never have a sideeffect in real life while providing significant real life benefits. -igor My 2c, Eelco - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Re[2]: Alternative to Wicket data binding
the processing impart would be nil because we cache a lot of the information. however forcing wicket annotations on middle tier objects is not a very good approach. if people really wanted to do this they can create this kind of annotation themselves and then install a security manager that would check it. i really dont think this is breaking encapsulation. i will concede that there is one case where it can break encapsulation and that is when you start out with what is publically accessible and then later you change your mind and make it completely private, but forget to remap the property model. it is a case where it is easy to make the mistake of not updating property models. all other cases i believe are unimportant because you would have to go poke around the class to even know that private field is there to start with. -igor On 8/25/07, Oleg Taranenko [EMAIL PROTECTED] wrote: Hi Igor and Eelco, Sorry, for interventing in your discussion :) May java annotations can help us?

How it lead to additional lag on processing the model, i can't estimate. Cheers, Oleg all i asked johan to do was to tweak property resolver to allow access to private stuff. i was under the impression that the property resolver always tries to access the getter/setter first, then the field. half of this thread you are arguing that we shouldnt allow access to private fields/methods and half of it you are arguing that we should but try the getter first, so im pretty confused. No, again, I'm arguing to *either* allowing access to all private, or don't allow it at all. I am not against private member access per se, just want it to be consistent.
