newbie problem witch wicket...
Hi Im developing with Wicket for short time so forgive me if I misanderstood some Wicket concepts. Recently I was asked for develop SSO-like feature for Wicket powered web application. Application uses wicket-auth-roles + Acegi for securing wicket pages. What I have to do is to let authenticate users to this web app only by typing URL in their web browsers (or clicking some prepared link). This URL will contain username and password but user will not be forced to fill in any form or press any button - just typing url or cliciking some prepared link. Actual way of uthentication (via Wicket page) must remain, so there will be two ways to login to application: either by filling in form or typing url in web browser. Because this application is using wicket-auth-roles what I have to do is to retrive from request user login and password and call signIn(username, password) on Session object. This is the moment where problem begins (for me). I've tried to write simple servlet to do this but when I've accessed Wicket session by: Session.get() runtime exception was thrown because Wicket session cant be created outside request cycle... ...so I decided to do this inside request cycle, but actually I dont know any simple solution to execute some code (after sending bookmarkable request) and redirect to some WicketPage. What I need is something like BookmarkablePage but dont displaying any page, only redirecting to other page (after executing autentication,or some other code), something which might be called BookmarkableAction ;). Probably it is possible to write custom request target and extend request target processor (to create such target) but it looks too complicated for me to perform some simple task. In action oriented frameworks (Struts/SpringMVC/...) its trivial, I know that Wicket is page oriented framework but Im wondering if there is any support for such 'actions'. Maybe there is some other way to achive such SSO-like feature ?

Re: newbie problem with wicket...
I don't have secure base page because project is using wicket-auth-roles with AnnotationsRoleAuthorizationStrategy so there is no need for such page. Maybe I misunderstood your idea ?

Re: newbie problem witch wicket...
Hi It's some idea but I think that its a little bit of hacking (sending GET request to formSubmitListener). I found other (are they better ?) solutions: 1)Use usual WebPage and in constructor of this page write code to execute and then at the end call setRedirect(true) and setResponsePage(somePage) 2)Use Statless page and statless link, write code in link onclick method. Both solutions assume that acces to this page is done through 'bookmarkable' URL. None of these two solutions satisfy me completly because each of them is some kind of hacking for me. In first aproach we use Page constructor to execute some code/action not to display page, this page even doesnt need any markup file (it will never be rendered), whats more, replacing responsePage in constructor of another page looks strange - for me it is breaking of contract(or maybe my understanding) of WebPage. In second solution we use statless page and statless link not to display link to the user but just to allow call any code/action throught 'bookmarkable url'. For me this is also breaking of statless page and statless link contracts. Because both of this solutions work, I probably choose one of them but Im curious why there is no support in wicket for such (simple in action based framework) cases (or maybe there is but I cant find it ?). For me it will be great if I could create 'action' like class and call it from wicket (inside request cycle) and forward/redirect to some page. I think it could be done by extending RequestCycleProcessor (to accept wicket:action url) and write new base class for ActionRequestTargets. I know that Wicket is page oriented framework but wouldnt be great if it could also support some simple 'ations' ? As I said Im new to Wicket and maybe it is impossible or its breaking some of wicket vision/assumptions ? What do you think about such feature ? Of course when nature of web application is rather action then page oriented we should use some of existing action based frameworks, but I think (as newbie) there are scenarios where in page oriented application such feature (call some code inside request cycle and redirect to page) will be very helpfull.

Re: newbie problem witch wicket...
Its very similar to my solution number 1. Instead of executing
setRedirect(true) and setResponsePage(somePage) you propose to throw
RestartResponseAtInterceptPageException.
Could you explain why its better to throw this exception rather then
redirect to resposne page ?
If I understand RestartResponseAtInterceptPageException class it is usefull
when we would like to come back to the page where this exception was thrown
(to MyBookmarkableSimpleSignOnPage in your example) I think this is not a
case in this situtation. However your solution is similar to main so its
make me sure to choose solution number 1.
According to security concerns, I know that passing username and password in
'plain' link its not the most secure way but I wanted to keep my example
simple (witout any tokens etc), but thanks for your comment.

PropertyModel type of key map
Hi Im trying to 'force' PropertyModel to put into map key different then String but after few trials I have no idea how to do this. Example: I have field myMap in my page initialized as follows: Map myMap = new HashMap(); then I create property model for my page(this == page containing myMap field): PropertyModel p = new PropertyModel (this, "myMap[123]"); now when I execute: p.setObject(true); model puts into map expected boolean but key is of type String not Long. How I can force this property model to put with key of choosen class (in this example Long)?

Re: PropertyModel type of key map
If there is no option to force (why? I can imagine setMapKeyClass method in PropertyModel...) PropertyModel to do this and I have to use different Model, I would like to ask does Wicket(or one of Wicket subprojects such as WicketExtensions) provide such ready to use model ?

Re: PropertyModel type of key map
Ok, maybe you are right that adding such method to PropertyModel will make it bloated, but I think that some model dedicated to work with maps(MapModel ?) will be nice feature of Wicket. I know that questions bellow dont stick to the subject of this thread but maybe you can help me with them. Recently i started to 'study' Wicket API and Wicket sources and have two questions(so far ;)): 1)What IChainingModel interface is for ? I thought that it will be used inside model implementations in getObject method checkig if nested model object is a ChainingModel object but the instance of operator in this methods checks against IModel interface (what is correct). If I understand Wicket API correctly it is possible to implement some model with chainnig ability without implementing IChaininig model - its internal implementation of get/setObject methods. Could you explain me what I(or rather my model) gain when my model implements IChaininigModel interface ? 2)When I looked at getTarget() method inside PropertyModel class I found that retriving of model object is done inside a loop. I dont understand why PropertyModel cares about how nested model is implemented. Why it cares ? because it checks if object returned but nested model is another nested model or not. I thought that retriving of model object is responisbility of each model class individually and PropertyModel should only check if its model object is IModel object (if so return ((IModel)myModelObject).getObject) or is it a 'real' model object(if so return it). Answers for this questions will help me implementing my MapModel class.

few (not only) AutoCompleteTextField questions
Hi, First, problem description: Recently I was asked to change DropDownChoice field into AutoCompleteTextField. Everything was ok untill I noticed that old DropDownChoice field has attached OnChangeAjaxBehavior. Ofcourse what works well with DropDownChoice doesnt work as I want with AutoCompleteTextField. The problem is that I want to update a model after user selects one of choices(from autocomplete) not after any change of text field. I found getOnSelectJavascriptExpression method in AbstractAutoCompleteRenderer (since Wicket 1.4 ?) and I thought that it would be a good place to call some JS to update text field model. I looked at http://cwiki.apache.org/WICKET/calling-wicket-from-javascript.html to see how to call server side Wicket code from JavaScript. Next I had the idea to attach to text field AjaxFormComponentUpdatingBehavior and call its getCallbackUrl() from JavaScript returned from mentioned earlier getOnSelectJavascriptExpression(). The problem is that AjaxFormComponentUpdatingBehavior expects event name in constructor - in this case I dont need any onXXX event because I will call its getCallbackUrl() directly from JS. Now few questions: 1)How to update (via Ajax) model of some FormComponents from JavaScript? Do I have to attach AjaxFormComponentUpdatingBehavior to some dummy event and call its getCallbackUrl() directly in JavaScript ? If so, its kind of hacking for me and AjaxFormComponentUpdatingBehavior should provide no-argument constructor. 2)Does JavaScript returned from getOnSelectJavascriptExpression is called after corresponding TextField value has been set ? 3)At Wicket wiki I found description how to work with AutoCompleteTextField and Models: http://cwiki.apache.org/WICKET/autocomplete-using-a-wicket-model.html I dont understand why this problem is not solved by subclassing directly form AutoCompleteTextField and overriding getConverter and provide some custom converter ? Ps. My colegue told me to attach AjaxFormComponentUpdatingBehavior to onBlur event, maybe this is the solution ? (but still, for me better place to update a model is in Javasript from getOnSelectJavascriptExpression() than in onblur event handler...)

I was confused because I started with OnChangeAjaxBehavior and it was broking AutoCompleteTextField - thats why I started thinking of diffrent approaches. BTW. Why AjaxFormComponentUpdatingBehavior works well with AutoCompleteTextField and OnChangeAjaxBehavior doesnt ? Is it a bug in OnChangeAjaxBehavior or the purpose of this class is different ?

Re: DataTable cell link
Hi I dont know wicketopia project (and any of its classes like FragmentColumn) so I can misunderstand your idea but as far as I am able to read that code It looks like you are adding a link to the table cell, not making a cell itself a link.

Re: DataTable cell link
All this solutions are correct but the problem is not in attaching some
custom Javascript to element (which can be done in multiple ways) but
in making td element work as a link.
What exactly should I do to achive this ? What components should I add at
server side at what JavaScript should I render at markup ?
If I have to copy-paste bunch of Link class code it looks like some
design/implementation problem of DataTable (or one of components it has).
Its really supprising that such common issue is such problematic.
I hope there is some simple and intuitive solution(if I find one I'll post
it here)
Thanks for your help

Re: few (not only) AutoCompleteTextField questions
Textfields do recive onchange event, even AutocompleteTextField has modified
version off onchange event handler.
Whats more new AjaxFormComponentUpdatingBehavior("onchange"){..}; works well
in this scenario but
OnChangeAjaxBehavior not.
I looked at OnChangeAjaxBehavior implemenation and this is a subclass of
AjaxFormComponentUpdatingBehavior class with super("onchange"); call in its
constructor.
This class only provides its own implementation of onComponentRendered
method so there should be a problem.
When I looked at OnChangeAjaxBehavior class contract description in JavaDoc
("A behavior that updates the hosting FormComponent via ajax when value of
the component is changed. This behavior uses best available method to track
changes on different types of form components.") there is no mention that it
shouldnt be used with some components so I think its bug either in
OnChangeAjaxBehavior class or AutocompleteTextField class.
Correct me if I'm wrong.

Re: DataTable cell link
Exaclty, problem is with 'consuming' td element by Item object.
The problem is that if you have wide column but short text in it some users
have problem with hitting the text (which is a link) .The idea is to make
whole td element 'clickable'(or linkable).
The solution would be if table could have any component as row or cell
element not only Item object.
But I know that this is a big change in DataTable class (or one of its child
component class) .

Re: DataTable cell link
Hi,
Thanks for help but the problem with your solution is that it doesnt work in
IE (when I have multiple columns with such links only links in first column
'fills' entire cells) in Firefox that works.

Re: DataTable cell link
Because I havent found better solution then adding 'onclick' handler to
cellItem I have to do it your way.
I looked at urlFor methods in Component class and didnt found the one with
Component attribute.
How should I generate url for Link component, AjaxLink or AjaxFallbackLink ?
Do I have to add this components to the page and set its visiblity to false
?
I understand 'general concept' of this solution but dont know how to
implement this in specific scenarion (ie. linking to Link, AjaxLink,
AjaxFallbackLink).
Using diffrent repeater could be a option but DataTable (or
AjaxFallbackDefaultDataTable) provides a lot of functionality (sorting,
paging, fallback links etc) so it would be a waste of time to implement its
from scratch just because its hard to make a table cell (or row) a link. It
must be a way to achive this... if not it serious limitation of DataTable
component.

Re: DataTable cell link
My colegue point out that for Ajax requests AjaxEventBehavior can be used,
and it works fine. so now I need only solution for normal (non Ajax)
requests.

Re: DataTable cell link
That was the solution I was looking for.
I havent know that it is possible to do thinks that way !
I supose that I have to override newCellItem and newRowItem method in
DataTable class and return ClickableItem instead of Item.
Good to know that it is possible to do this in standard Wicket way without
'magic code'. Although it works and all classes follows their contracts in
my opinion it would be more coherent and obvious if DataTable could work
with any somponent as cell/row but its only my notice...

testing borders with WicketTester
Hi Is it possible (if not why?) to test Border components in a way similar to testing Panels ? -WicketTester.startPanel(TestPanelSource) ? Its strange but I cant find corresponding method for Borders. Thanks in advance.
