Hi,
In my project we often have the case where a user initially is allowed
to construct a certain component (pages mostly) but whether he really
can depends on the model of the page.
So my request / suggestion is to enhance IAuthorizationStrategy with
the following method isInstantiationAuthorized(Class, IModel). whether
this methods is made available next to
isInstantiationAuthorized(Class) or replaces it is not important.

As far as i can see the following changes need to be made
-Application.notifyComponentInstantiationListeners needs to be
upgraded to receive the model to, or the component should not call
notify untill the model has been set on the component (which happens
on the next line)
-the default listener needs to pass the model to the strategy.

For regular models this should not be a problem but IWrapModels might
have a problem when accessing anything else from the component but the
id. Not passing the wrappedmodel but the original model is imo not an
option because the main point of passing the model is to be able to
use the getObject method.

What do you think?

Re: [Wicket-user] feature suggestion component instantiation

2007-07-18 Thread Johan Compagner

i can see the value of having the model in the authorizationstrategy
this is pretty handy. But the problem is with wrapmodels  because we
just can't give those to the outside world withing a constructor of a
component
because we have a big warning in the wrapOnAssigment(Component) call
that in that method you shouldn't really touch the component because it is
not
fully constructed yet. But we can't have it that the component is still not
fully constructed
in the getObject() call of the wrapped model.

So i am +1 for such a change except that the model param will be null of not
given and
null if it is wrapped model.

Re: [Wicket-user] feature suggestion component instantiation

After having Johan explain to me that It is only the
IComponentAssignedModel that will cause serious problems and models
like CompoundPropertyModel will work just fine. And since we do not
use those.
I have no objection to this restriction.

Re: [Wicket-user] feature suggestion component instantiation

I don't think I agree with that.

MyComponent c = new MyComponent(); c.setModel(foo) wouldn't work for
starters, and you can even set models mutliple times. Not to mention
the other problems you mentioned in this thread. And finally, it would
just invite people to go crazy with this functionality.

But give us a good example of where using the model to determine an
access restriction would actually be useful?

Re: [Wicket-user] Ajax component replacement with updated Model issue

2007-07-18 Thread Timo Rantalaiho

On Sun, 15 Jul 2007, Erik Dreyer wrote:
 Everything is working great except the 'display' component is not reflecting
 the saved changes.  Before replacing the edit component
 with the display component, I'm calling setModel() on the original display
 component with the updated data.  This has no effect visible effect.

I saw that you already solved this by calling onModelChanged().
I think that if you use setModelObject() it does that call so
you don't need to call it explicitly. You could also see if
just using the same model instance for both edit and display 
component would do the trick. The equals() implementation of
the model object might also affect the behavior, because as far
as I remember the onModelChange-things get triggered only when
!newModelObject.equals(oldModelObject).

 The 'display' component is itself a tree of components.  Is there a
 prescribed way to propogate the fact that I updated the model down
 to all the affected child components?  Is that something I have to handle
 myself or does the framework do that?

I think that sharing the model is a common trick. Note that 
you can also nest models, if you e.g. need CompoundPropertyModel
handling the same data that is in another kind of IModel
elsewhere.

Re: [Wicket-user] feature suggestion component instantiation

True you can't do setModel(foo) and expect your instantiation check to
work. Which imho is perfectly logical if you want to use your model in
the instantiation check you need to pass it in the constructor.

As for the example
We have a search page for students, uppon clicking on one of those
students, you go to a detail page for that student. that page also
contains several tabs to go to other relevant pages for the student
(like it's school grades). on these pages we made a quicksearch
function with contains amongst other things 2 buttons to navigate
forth and back between the searchresults of the search page, while
keeping the same view. Suppose i have sufficient rights to see the
detail pages of all students but only enough rights to see the grades
of my own students.

So if i make the search wide enough to get all students and then
select one of my own, going to the grades. That's fine. But if i then
navigate to another student i am not allowed to see the grades
(creating a new instance of the grades page in the process) i need to
know if the page in combination with the student is allowed, because
the page itself is basically allowed.

Re: [Wicket-user] Modal Window and Page Expired.

2007-07-18 Thread 王磊

I want to descript the context.
Some one write a web application based on wicket.Many pages uses ajax.
I encoutered a strange problem.
After 5 ajax modal windows are poped up.The brower will give me a warming 
dialog to tell me that the current browse page will be closed.Then the page is 
redirected to a login page.Sure ,this means the session is out.

I tries someway:
1 Clear the IE cookies.
2 Clear the tomcat workdir
3 force the tomcat use url-rewrite mode.
4 close the IE cookies.

Then the application works fine.
Maybe you need close the browse cookie and use tomcat url-rewrite both.
Try it.

  Hi all,

 There was a post last December about the same problem that I'm facing
 right now, which is getting a page expired error page after I close a modal
 window.
 The post was called Firefox and ModalWindow and seemed to talk about the
 issue for FF only.
 I've encountered the problem first with FF (2.0.0.4). After reading the
 post, I tried with IE7 and it worked ok (that was this afternoon).
 This evening, neither IE7 or FF work anymore. Darn! Clearing cookies and
 stuff don't change a thing.
 Oh, and of course, the Ajax ModalWindow example works just fine (my code
 is heavily inspired from that example)...
 I'm using Wicket 1.2.6, Tomcat 5.5.20, Jdk1.6u2.

 Have you guys shed any light on this issue at all?
 I've tried to trace the code, but as I'm rather new to Wicket, I couldn't
 really figure out what's going on...

 Anything I can do to help address this?

 
 i wonder, clear cookies in firefox and try again. i know there was a similar
 problem if you didnt set the cookie name in the modal window using
 setcookiename(), but looks like you did that. still, try clearing the
 cookies.

 Below is the code I use, just in case.

 Reagrds,

[Wicket-user] Random ModalWindow exception

2007-07-18 Thread Alex Objelean


I have a strange issue when using ModalWindow in my application. Sometimes
(randomly), I got the following error in ajax-debug window:

[MESSAGE]

INFO: Response parsed. Now invoking steps...
ERROR: Exception evaluating javascript: TypeError: Wicket.Window has no

[/MESSAGE]

The reason, seems to be the fact that the modal.js is not always included. I
didn't manage to find out why this is happening. Can anybody help me?

Re: [Wicket-user] Random ModalWindow exception

2007-07-18 Thread Alex Objelean


I am using wicket-1.2.6.

Here is a short background description of the problem:

I have a page, which contains an AjaxTabbedPanel. The panel contains div
wicket:id=modalWindow/div markup to hold the ModalWindow component. 

I think that the modal.js is included (at least for its first call), but
have problems when the ajaxTabbedPanel is updated via ajax.

Any thoughts?

Thank you,
Alex.

Re: [Wicket-user] feature suggestion component instantiation

However besides the benefit of being more efficient it also prevents a
lot of nasty stuff like throwing custom exceptions / NPE in the page
constructor or redirecting, which i now have to take into account
because the page is fully constructed. When the strategy can tell me
for certain if the page is allowed i would not have to do that.

[Wicket-user] Nesting AjaxTabbedPanels when using AjaxLink

2007-07-18 Thread Jeff Pierce

I am new to Wicket and just getting my feet wet and looking for some
advice.  I have an app I am building that contains a main row of Ajax tabs
across the top.   Each tab's panel will have the following layout.  A set of
menu's on the left and a set of tabs on the right for part of its content
area.  I want the menu's to be Ajax links and the tabs to be Ajax tabs.
When the user clicks on a menu choice, the content area should reload with a
different set of ajax tabs.

My question is what is the best way to hookup the ajax links to change the
portion of the page that contains content area which includes a different
set of tabs depending on the menu choice (stuff in red below)?  I have the
tabs and subtabs loading OK, but not sure how to go about hooking up the
ajax menu choices to change the subtab panel.

Here's the basic layout:

-
Page header area
-
| *MainTab1* | MainTab2 |
-
|*Menu1* |
| Menu2  || *Menu1Subtab1* |Menu1Subtab2|
| Menu3  ||
| Menu4  ||
|||  Menu1Subtab1 Tab panel Content Area
||
-
Page footer area
-

Thanks

 obviously whatever this thing is, another thread is modifying it, or you

what you should do is instead of returning an iterator directly first copy

[Wicket-user] navigating up from a frame

2007-07-18 Thread salmas



I am within the right frame of a frameset. The frameset has a tree in the
left frame. When the user clicks most of the links in the tree I want to
refresh the right frame. However, sometimes I want to navigate to a
frameless page (tree gone and show another frame in the app). I don't know
that I need to do this until I am inside the right frame and check a
setting. I should do this automatically and not have a user click a link or
something. When I do setResponsePage(MyPage.class);  from within the right
frame only the right frame refreshes. How can I replace the entire frameset
with MyPage.class?

Thanks

 Subject: Row index in datatable

 hello all,

 I need to obtain row index in datatable when populating cell item.
 column = new AbstractColumn(...)
 {
  public void populateItem(Item cellItem, String componentId, IModel
 model)
  {
 cellItem.getIndex() // Index of column
 ??? // Index  of row
 cellItem.add(...);
  }
 };

 After some deep research, i found same question posted

 http://www.mail-archive.com/wicket-user@lists.sourceforge.net/msg21743.html
 but no answer except an hack which don't work with wicket 1.3b2 (and
 didn't find the feature in JIRA).
 If someone can help me :P

i guess ingram never filed that jira request :( maybe you should

if this doesnt work:
((Item)cellItem.getParent()).getIndex()
then this will
((Item)cellItem.findParent(Item.class)).getIndex()

Thanks in advance.

Re: [Wicket-user] Random ModalWindow exception

 I am using wicket-1.2.6.

 Here is a short background description of the problem:

 I have a page, which contains an AjaxTabbedPanel. The panel contains div

 I think that the modal.js is included (at least for its first call), but
 have problems when the ajaxTabbedPanel is updated via ajax.

 Any thoughts?


first try 1.2.6 branch. i know this is a problem that happens somewhat
rarely, but so far no one affected by it has been able to produce a
quickstart that replicates it. so we cant fix it. maybe you are that someone
:)

Re: [Wicket-user] feature suggestion component instantiation

what does your strategy do? it redirects right? you do that with throw new
RestartResponseException - you can do the same from your constructor once
you check your model. it isnt that much later that you would fail - only
the init of super hierarchy.

Sounds to me like you have alternative ways to implement this, for
instance, construct what's on your page according to what can be
displayed, throw an auth exception in the page itself (doesn't sound
like you were doing this generically to start with?) or use an
intermediate page that functions like a switch. Also, if you really
want to follow your approach and IComponentInstantiationListener is
not rich enough, consider using AOP, which should give you all the
freedom you wish for.

Re: [Wicket-user] feature suggestion component instantiation

i am -1 on this

first of all there are already too many exception to this: it wont work if
its a wrap model, it wont work if its icomponentassignedmodel, blah blah
blah.

if i construct my component with new Component(id, foo) and foo is not
null then it is very clumsy that sometimes in the auth strategy it is all of
a sudden null and other times is not even though the exact same line is
executing. i bet a lot of people will be filing bug reports.

also i really wish we would limit passing around instances of not fully
constructed objects to users. we already do it in some places where it is
very strictly necessary, but we should not do this lightly.

i do not wish something like this introduced just to make maurice's life a
little easier, sorry maurice nothing personal.

On 7/18/07, Jeff Pierce [EMAIL PROTECTED] wrote:

 I am new to Wicket and just getting my feet wet and looking for some
 advice.  I have an app I am building that contains a main row of Ajax tabs
 across the top.   Each tab's panel will have the following layout.  A set
 of
 menu's on the left and a set of tabs on the right for part of its content
 area.  I want the menu's to be Ajax links and the tabs to be Ajax tabs.
 When the user clicks on a menu choice, the content area should reload with
 a
 different set of ajax tabs.

 My question is what is the best way to hookup the ajax links to change the
 portion of the page that contains content area which includes a different
 set of tabs depending on the menu choice (stuff in red below)?  I have the
 tabs and subtabs loading OK, but not sure how to go about hooking up the
 ajax menu choices to change the subtab panel.

 Here's the basic layout:

 -
 Page header area
 -
 | *MainTab1* | MainTab2 |
 -
 |*Menu1* |
 | Menu2  || *Menu1Subtab1* |Menu1Subtab2|
 | Menu3  ||
 | Menu4  ||
 |||  Menu1Subtab1 Tab panel Content Area
 ||
 -
 Page footer area
 -


you have to replace the entire tabbedpanel that holds the menu1subtab links.

so menu1link.onclick(target) {
ajaxtabbedpanel newone=new menu1tabbedpanel(...);
menutabbedpanel.replacewith(newone);
menutabbedpanel=newone;
target.addcomponent(newone);
}

Get it out of my system? I'm not exactly recommending AOP as I think
other solutions would be better.

after(Component c) returning: this(c)  execution(Component.new(..)) {
System.out.println(constructed component with model  + 
c.getModel());
}

Something like that works. I'm sure there's lots of ifs and buts, but
the point is that it is a possible way out.

[Wicket-user] Overriding ID attributes

2007-07-18 Thread mperham


We are migrating our existing application from UI framework XXX to Wicket and
we have a boatload of UI automated tests which depend on the ID attribute of
our form inputs to drive the tests.  I'm trying to figure out how to get
Wicket to use the exact same IDs when it generates the HTML as with our old
system.  Here's an example of the generated HTML where I have a DropDown
within a Form:

td class=label
divlabel for=form_selBusinessServiceBusiness Service/label/div
/td
td class=input
  select name=selBusinessService id=form_selBusinessService
option selected=selected value=Choose One/option
option value=http://www.test-sdk/sdkl#Fetch_COB;Fetch COB/option
option value=http://www.test-sdk/sdkl#Status_Visibility;Status
Visibility/option
option value=http://www.test-sdk/sdkl#Claims_Submission;Claims
Submission/option
  /select
/td

Now the actual ID of the select should be selBusinessService and that's
the wicket:id of the component in Java but Wicket prepends the component
hierarchy, I guess, when auto-generating the id attribute in HTML.  Now I
can use an AttributeModifier to adjust the value of the ID but the
SimpleFormComponentLabel does NOT reflect that change in the for attribute.

Is it possible to do this?  Can I completely override Wicket's ID handling
and just have it use my specified ID?

Re: [Wicket-user] Overriding ID attributes

i dont remember how similar the markup id handling code is between the two
versions, but all i did was add this:

/**
 * Sets this component's markup id to a user defined value. It is up to
the
 * user to ensure this value is unique.
 * p
 * The recommended way is to let wicket generate the value
automatically,
 * this method is here to serve as an override for that value in cases
where
 * a specific id must be used.
 * p
 * If null is passed in the user defined value is cleared and markup id
 * value will fall back on automatically generated value
 *
 * @see #getMarkupId()
 *
 * @param markupId
 *markup id value or null to clear any previous user defined
 *value
 */
public void setMarkupId(String markupId)
{
if (markupId != null  Strings.isEmpty(markupId))
{
throw new IllegalArgumentException(Markup id cannot be an empty
string);
}
setMetaData(MARKUP_ID_KEY, markupId);

}

Re: [Wicket-user] Modal Window and Page Expired.

2007-07-18 Thread Laurent Brucher

Cookies have been cleared many times, without any success ;-)
 
But I found out what is causing (directly or indirectly) the problem:
In the page that includes the ajax button that is used to bring up the modal
window, there is a wicket:head section at the top of the page.
If I remove this wicket:head section, there is no problem with the modal
window anymore.
 
The page globally looks like:
html
head
...
/head
body
wicket:head.../wicket:head
wicket:extend

/wicket:extend
/body
/html
 
Somehow, I've noticed that including the wicket:head triggers an
additional HTTP request to the same URL (that is, the URL to display the
above page).
Dunno why this is happening but the end result is that the pagemap then
contains 2 versions for the same page ID.
Then, when I hit the button that brings up the modal window, the framework
is trying to access the above page, version 0. This has the effect of
putting that page's version at the top of the pagemap's access stack
(PageMap.access() method). By doing this, the version 1 of the page is
removed from the access stack, but also the page itself (call to
PageMap.remove(Page)).
Thus, once the modal window gets closed and the original page needs to be
rendered, we get a page expired since it was removed from the cache.
 
That's as far as I can describe what I've seen  understood tracing the
code.
I'm not sure where the problem lies: second request because of the
wicket:head or incorrectly evicting the page.
 
Maybe there is something funky in my own code but I don't see what. Or maybe
there is an issue here.
Any input would be helpful at this point.
 
Thanks!
Laurent.

There was a post last December about the same problem that I'm facing right

The post was called Firefox and ModalWindow and seemed to talk about the
issue for FF only.
I've encountered the problem first with FF (2.0.0.4). After reading the
post, I tried with IE7 and it worked ok (that was this afternoon).
This evening, neither IE7 or FF work anymore. Darn! Clearing cookies and
stuff don't change a thing.
Oh, and of course, the Ajax ModalWindow example works just fine (my code is
heavily inspired from that example)...
I'm using Wicket 1.2.6, Tomcat 5.5.20, Jdk1.6u2.
 
Have you guys shed any light on this issue at all?
I've tried to trace the code, but as I'm rather new to Wicket, I couldn't
really figure out what's going on...
 
Anything I can do to help address this?


i wonder, clear cookies in firefox and try again. i know there was a similar
problem if you didnt set the cookie name in the modal window using
setcookiename(), but looks like you did that. still, try clearing the
cookies.

I have not yet had a real need for IOC, but when I last looked some
years ago, picocontainer looked pretty nice.  We do have guice now,
but I think it would be great to integrate Wicket with picocontainer.
Unfortunately, I'm not aware of anyone doing this work.

Re: [Wicket-user] Setting up project - images and stylesheets


I'd just use a wicket.markup.html.image.Image for each of the images, and
let wicket rewrite the src part of the img tag.  Then you can put whatever
you want in the src attribute.

Thanks.  Is that common practice?  It seems like it tightly couples the java
code with the design of the web page.  I thought the Image class was for
creating dynamic images - as that's all I've needed to use it for.

I wonder what happened to the wicket:preview tag...

Another option is to use:

html
head
wicket:remove
link src=../../../../../src/main/webapp/style.css /
/wicket:remove
/head
body
etc.

But basically I've become quite proficient in reading HTML and classes
so I don't need the preview of the stylesheets anymore (it is not like
netbeans preview renders the same as, IE6 or IE5.5, which are browsers
from the 9th level of hell).

The best process I've come up with is:
- make preview/dummy mockup of your site
- ensure it is all CSS enabled, making development a blast
- copy dummy site to your packages
- split pages into panels, apply markup inheritance
- move stuff around to fit a nice package model
- sprinkle wicket:id's in each page/component
- run the application in the debugger, dev mode and fill in the behavior.

Stylesheet and general javascript go into the context root. If
something special needs to be developed (geeky JS or such), I usually
do a spike/prototype and then incorporate back into the app.

I'm not sure how I should best link to stylesheets and images in my NetBeans

For example, if I have the following code in my MyPage.html page:

lt;img src=images/logo.pnggt;

...and I run the application, the image will reference web/images/logo.png.
However, if I just quickly view that HTML file, it will reference
src/java/package/images/logo.png and the image link will be broken.

Is there a good way to set up the project besides keeping duplicate images
and stylesheets both in the source code dir and the web dir?

I realize if I move the HTML files to the web directory the problem will be
solved but I'm trying to stick with the Wicket way of doing things for now
(.HTML right next to .java in the source)

Thanks

Thanks I'll have to take a look at it.  I'm still using 1.2.6 and I believe
ContextImage is only in 1.3.  (I thought it would be hard to learn 1.3 if
any of the examples are broken).

This seems to be closer to the solution be it still forces me tightly couple
the java and html code.  Shouldn't web designers be able to modify the HTML
'template' without touching any Java code?

I was hoping for something like a single application setting:

@Override
protected void init() {
this.getMarkupSettings().setImagesRelativeToRoot(true);
}

2007-07-18 Thread landtuna



 Thanks.  Is that common practice?  It seems like it tightly 
 couples the java code with the design of the web page.  
 I thought the Image class was for creating dynamic images - 
 as that's all I've needed to use it for.  

To be honest, I don't know.  If you don't want to put wicket:id attributes
in your images, maybe you could instead put some Javascript in a
HeaderContributor that rewrites the src attributes of all your images (or
all the ones of a particular css class) when the page loads.  This could fix
their paths while still letting their paths remain original in the raw HTML. 
(They wouldn't get changed because the script wouldn't get loaded.)

Re: [Wicket-user] java.util.ConcurrentModificationException with RefreshingView (AGAIN!?!?!!)

2007-07-18 Thread Ballist1c


It IS very possible I am going about this from the completely wrong angle... 

The gist of it is, that a whole bunch of users will be reading all the
entries from the same vector in an asynchronised manner. So what I thought
that each user would require their own Iterator to keep track of their
progress through the Vector ... 

The only actions I performed on the vector is adding to it.  I am thinking,
once the iterator is retrieved from getItemModels() does RefreshingView
store the iterator within itself for the duration that its being displayed?
cause if that is the case, i am thinking i dont even NEED to be storing the
iterator with each user!

Re: [Wicket-user] Setting up project - images and stylesheets


Thanks, using wicket:remove sounds like a good idea.  Unfortunately, my CSS
skills are really lacking - so maybe this will motivate me to learn how to
use CSS to layout pages instead of tables.

Either that or all my image references will look like this :)

wicket:remove ../../../../../src/main/webapp/images/logo.png
/wicket:remove images/logo.png

Re: [Wicket-user] Setting up project - images and stylesheets

simply do this

have your images be relative

img src=images/logo.png/

in runtime wicket will rewrite them to be relative to context root

in devel time put this into head

wicket:remove
base href=../../../path/to/your/webapp/folder/
/wicket:remove

so at devel time your images will also be relative to context root.

Nope. You just have multiple references to the same object. Java's
serialization is smart enough to make that distinction.

Re: [Wicket-user] java.util.ConcurrentModificationException with RefreshingView (AGAIN!?!?!!)

2007-07-18 Thread Ballist1c


got it I definately was trying to extend there scope for something they can't
be used for :), 

my goal is to get the users to only render what they have to in the vector. 
I do not want them to have to re-render the entire Vector each time. The
vector will be constantly added too, there are no modifications to existing
data however. having the user re-render the entire vector becomes
impractical.  

I have done some reading on nabble and I require the page to display the
current items without having to re-render them, and rendering new Vector
items as they become available.  From what I can see, the solution to this
lies in javascript DOMs... *sigh*... im allergic to javascript :)  

Thanks for your assistance again igor.

Re: [Wicket-user] Setting up project - images and stylesheets

Thanks Igor.

I don't believe this works offline (atleast under firefox in ubuntu). It
works fine if I put a real web URL (i.e. http://www.google.com).

I've tried all sorts of combinations (relative and absolute). I may be
specifying the absolute path incorrectly. I tried 3 and 4 forward slashes
(since on linux root is '/')

href=file:///home/blah/blah, href=file:home/blah/blah,
href=../blah/blah. Each time, I tried using /images/logo.png and
images/logo.png. It seemed to ignore the base tag unless it specified an
http address.

head
titleMyTest/title
base href=file:///home/user/projects/mytest/web/
