Re: Gant like component in wicket

[lizz]

Yes I know but this should be displayed in a wicket web page and the number
of tasks types is not static (it is based on the page datamodel
(CompundPropertyModel), so I think i need a wicket component for generating
the html when the page is created).

Hi!

I have done a somewhat similar looking element with divs. All you need
is to tell the div its starting point, width and height and color, and
you get exactly what you want. If you want it to be clickable you just
put a link anchor around it (

Re: Gant like component in wicket

[lizz]

I would also like scroll bars to appear in both directions since I have a lot
of tasks.
Th horisontal scrollbar should only be below the taskbutton "column" so the
task names on the left hand side stays in a fixed position.
See http://www.java2s.com/Code/Java/Chart/JFreeChartGanttDemo1.htm
for a jfreechart gant chart example. (I only want scrollbars below the white
chart since the list of task names on the left hand side should be visible
when scrolling horisontally). The vertical scroll bar should be on the right
hand side of the white chart section but this scrolbar should scroll both
task names on the left and task list (white section) on the right (both
columns).

Gant like component in wicket

Has anyone made a gant like chart component in wicket?
I want to create a "gantlike component" where all the tasks are links and
are of html input type button. You should be able to click on them to
display specific information for that task and change the "task button"
background color based on some criteria. (I.e. make all the tasks that is

Thought about using a list in a list (Property list view). But not really

What kind of data provider are you giving it?  Couldn't you implement your
own ISortableDataProvider?

ISortableDataProvider dp = new SortableDataProvider() {
public Iterator iterator(int first, int count) {
// TODO Auto-generated method stub
// use this property to determine if that's the column
selected.  then sort by it
getSort().getProperty();
return null;
}
public IModel model(Post object) {
return new DBObjectDetachableModel(object);
}
public int size() {
// TODO Auto-generated method stub
return 0;

did you call setOutputMarkupId(true) and setOutputMarkupPlaceHolderTag(true) on

or leave it):

 - interfaces can be rapidly found with control-shift-t in eclipse by typing
"i"
 - resolves naming conflicts with annotations and classes without
compromises
 - code reads faster and more clearly because it makes functionality
immediately clear (you know when you can implement without seeing the class
definition so you can see the design better)

while it wasn't the most popular decision (and believe me, i do see both
sides of the issue because naming is very important to me when coding), it
does have some modest benefits and at the least (to me, anyway) it's simply
not an important issue. six of one. half dozen of the other. you do get used
to it.

Well, I'd imagine your way is the right way, since my way doesn't work
Though it works when I use the wicket tester.  This is most likely a bug,
but I am not keen on how to submit bugs and so on to the wicket developers.

I did not know of this.. I have always used the IChoiceRenderer's
getIdValue to distinguish between dropdown elements.. I have never
overridden the modelcomparator.

I wonder... which way is the right way :)

Wicket Not Using Custom Model Comparitor: Very Puzzling Behavior

[walnutmon]

I have dropdowns that are filled with domain objects, and sometimes the
objects are not equivalent literally, but should be treated as such.  I
created a subclass of the DropDownChoice...

class RelaxedComparisonDropDown extends DropDownChoice
{ ...constructor...
   @Override
protected IModelComparator getModelComparator(){
return new IModelComparator() {
public boolean compare(Component arg0, Object arg1){
DomainMember member =
(DomainMember)arg0.getModelObject();
DomainMember member1 = (DomainMember)arg1;
return member.getIdent().equals(member1.getIdent());
}};   }}

I then use this object in place of the drop down choice on my page.  This
doesn't work.  However, what's more puzzling is that when I test that page
it works just fine.  As a final test I placed a system.out in the compare
function.  The s.out gets called when running the test but not when the
application is deployed on my local server.

Very very odd.  I'm pretty much baffled, I hope someone can guide me in the
right direction.

Multiple Copies of One Wicket App

[Sean W]

Greetings,

I am trying to set up a single WAR (web app) that can use as many as 200
different databases depending on the request path.

Normally we have:
/ContextPath/WicketServlet/BookmarkablePage

I am trying to make:
/ContextPath/FileName/WicketServlet/BookmarkablePage

Where FileName is a configuration file on the server containing database
connection info.

Is there a way to pass this "FileName" to wicket's Application object? Is it
possible to use WicketFilter for this? I'm having trouble finding relevant
examples. Any help or alternate approaches would be helpful. 

Thanks!

FYI: I currently have a 1-web app, 1-servlet, 1-application setup. I
basically need to make a couple hundred seemingly-independent copies of the
same program (more multiple clients) using most efficient method.

Re: Back button + dataview problem

[Jeremy Thomerson]

Right - don't make your DAO serializable - the proxy thing should work.
Like Igor said, try a different container (run it up in Jetty with the
quickstart if you can - that should be quick and easy).

Let us know the results.  If it still happens, let us see the code where you
define the category dao.

UML Diagram of Wicket structure

[Eyal Golan]

Hi,
A few months ago someone sent a link that had a nice class diagram of
Wicket.
Can anyone point me there? I think it was a presentation about Wicket but
not sure.

OR,
Does anyone have a detailed Wicket class diagram?

Thanks

Re: Back button + dataview problem

[quizzical]

But if I have understood the docs  http://cwiki.apache.org/WICKET/spring.html
here  on the spring - annot project then categoryDao should be injected with
a serializable proxy which can get a categoryDao from spring when needed and
drop it when serialized.

 Hi everyone,

 I'm in the process of writing an example ecommerce app to get to know
 wicket
 and am really enjoying the experience.. At the moment I'm working on a
 page
 which allows you to browse through a list of items in a database.

 For the list of items I created a panel which uses a DataView with a
 SortableDataProvider and some orderByLinks, I also created a panel for
 viewing the available categories which controls the data the DataView
 is
 working on.

 Everything works fine going forwards, I'm running into problems with
 the
 back button. If I click on any of the links in these panels, then click
 the
 back button, then try and click another link I get a 'page expired'
 error
 page.

 Do I need to addStateChange on one of my components? If so which one, I
 can't find much info about Change and how it is meant to be used.

 If this is a simple problem and someone can answer my question easily
 then I
 will be very happy :) I have had a look through the forums but I
 couldn't
 find anything that helped me, it is possible of course that I was using
 the
 wrong terms. If there is not enough information here then let me know
 and
 I
 will write a test case and post that.

 Cheers very much
 Alex

scroll pane - panel with scroll bars - jquery

[lizz]

Has anyone implemented a panel with scrollbars (like the swing scrollpane)?
Preferably using jquery.
I have a list and want scroll bars to appear in both directions if the
content is wider/taller than the "visible area". I also have a component to
the left of this "scroll pane" that should listen to scroll events and
change when the vertical scroll bar is being scrolled so I cant use the css
overflow attribute. 


I should be quite similar to the dojo example
Orderable List with scroll 
in http://wicketstuff.org/wicketdojo13/
except i want scroll bars in both directions and i would like to use jquery. 

(Cant find the complete source code for this dojo example so I would
appreciate if anyone could tell me where to find it too...)

Hi Serkan

I am using the Start.java located in the test folder to startup the

The context path is removed there.
When I add a context path, then it is working fine. Both cookies is
created
with path /myproject.

But the problem exist if you remove the context path. This is the way i
run
it on my server and i guess that
this should also work for wicket. Can you confirm that you have the same
problem when removing the context
path.

/Murat

2009/1/7 Serkan Camurcuoglu 

  

is your application deployed to the root context (e.g. / ) ? Because


your


working cookie path is / while the cookie path that is not working is
something like /homepage/wicket:interface/:0: . In my setup (I'm
using
the quickstart project that you sent) the path of my cookie is always
/myproject which is the context path of the application. Can you repeat
the
same behavior using your own quickstart project? I suggest you to use
wireshark or live http headers firefox plugin to check the http headers
to
see what's going on..




Murat Yücel wrote:



Hi Serkan

I must have seen wrong before. I am getting the same thing as you have
described. The expire date is one month in the future.
The only difference is in the path variable. If you clear your cookies
and
type something in the input fields when mount is enabled.
Are you then able to see them again when you press the login button?

I have attached some screenshots of the cookie and the webpage I see
with
and without mount.

   In my case (when using mounted home page), when setting cookies,
   the expire time is automatically set as one month from current
   date, and when clearing cookies the expire time is it is set as
   01.01.1970.. It's really strange that the expire time is current
   time on your system..

   Hi Serkan

   I am using firefox 3.1 beta2, but i dont think that this is a
   browser
   related issue, because i am seeing the same behavior in IE7.
   The cookies are created for both FF and IE. The problem is
   that they get a
   expire date set to current time, which means that they
   are not available anymore. If i remove the mount they will get
   a expire date
   in the future and the typed value will stay in the input
   field.

   For example with mount i type admin in the first input field
   and password in
   the second. Press the login link and i see that the
   input fields are reset. If i remove the mount and do the same,
   admin and
   password will stay in the input fields.

   Hi Murat,
   It seems to work both ways in my setup. I'm using Firefox
   3.0. It
   successfully saves the username and password when I check

   the host, path

Re: Empty List

[Piotr Jakubowski]

I was thinking about, but I have to manually override the isVisible method of
every ListView I create (or create my own class that extends the ListView). 
Maybe ListView should by default have the isVisibility method defined so it
returns true if the list is empty? :) Just a humble suggestions for wicket
enhancement :)

Empty List

[Piotr Jakubowski]

Hello,
As I recently discovered XHTML specification does not allow empty lists. So
the markup like   is invalid. So there appears a problem with
ListViews, because when the list passed to the ListView constructor happen
to be empty we end up with invalid markup. 

Of course there is workaround like (let's say that we have the ListView with
wicket:id="myList")




But it is neither very elegant nor convenient. It is not very appealing to
me to seek for every list in the project and add this line. 

Do you have any other suggestion of doing this?

Back button + dataview problem

[quizzical]

Hi everyone,

I'm in the process of writing an example ecommerce app to get to know wicket
and am really enjoying the experience.. At the moment I'm working on a page
which allows you to browse through a list of items in a database.

For the list of items I created a panel which uses a DataView with a
SortableDataProvider and some orderByLinks, I also created a panel for
viewing the available categories which controls the data the DataView is
working on.

Everything works fine going forwards, I'm running into problems with the
back button. If I click on any of the links in these panels, then click the
back button, then try and click another link I get a 'page expired' error
page.

Do I need to addStateChange on one of my components? If so which one, I
can't find much info about Change and how it is meant to be used.

If this is a simple problem and someone can answer my question easily then I
will be very happy :) I have had a look through the forums but I couldn't
find anything that helped me, it is possible of course that I was using the
wrong terms. If there is not enough information here then let me know and I
will write a test case and post that.

Cheers very much
Alex

Re: Twenty Six Wicket Tricks

[Gwyn Evans]

Not sure if it qualifies as enough of a topic, but would some form of
overview/comparison/"when to use" syummary of the various URL coding
strategies be worth considering?

 Well, over the break here I've started something I swore I would never
 do again (well, two things, if you include the JavaOne talk I'm working
 on). I'm writing a (hopefully relatively short) book. It's called
 "Twenty-Six Wicket Tricks". Each trick in the book (lettered from A-Z)
 demonstrates something that people typically want to do and in the
 process builds a reusable and educational component. I've got 13 tricks
 coded up now and ideas for a handful more, but if there are any requests
 out there, please let me know. I'd also be interested in getting some
 idea how many people would be interested in this book (would provide
 some fuel for me to get it done). It does not cover any of the same
 ground as Wicket in Action (which you should buy if you have not
 already!), BTW. It's more of a companion to that book.

 Happy Holidays!

 Best,

Jonathan

Wicket-Jasper report

[freak182]

Hello,

I made a small utility based on wicket-contrib-jasper. The feature of this
tools is that the jasper report is now paging using PageableListView or
QueryDataProvider. And display in embeded pdf format.

Anyone is free to enhance this and distribute.

Thanks.

Re: URL fragment has unmatched key/value pairs

dear francisco


(i even had Fragment: admin, Fragment: bank-account , and things of the sort)


i´ve seen this too. for instance on hybrid encoding, if you mount a page 
to /foo, /foo/bar/ will bring this error, while /foo/bar/baz wont, 
because it means bar=baz in parameters.


i think you cannot do anything against someone playing with urls from 
outside.
unfortunately, i also see some instances of this with urls, i don´t 
think were generated by guessing:


URL fragment has unmatched key/value pair: 
resources/org.apache.wicket.markup.html.WicketEventReference/wicket-event


can anyone confirm that?
