RE: [Wicket-user] [Wicket] DataView and optimized item removal
I was just trying to get away from n^2 search, off the top of my head I
don't see a way around that without hashcode or a comparator.
I definetely don't want to reintroduce uniquekeyprovider, there is really no
more point to it.

You are right it does. I think it is a very common good
practice to impl hashCode when changing equals and it is not
so much more work if you need OIR at all.
However I do understand that you do not want to implement an
extra method.
We could either reintroduce IUniqueKeyProvider, change the
impl to equal to the underlying object or replace the HashMap
with a list (or make some reasonable helper).
What do you think?

Thanks Igor.
My anonymous cvs is a bit lagging.
Regarding the size thing, currently I use
IDataProvider.size(){return
Integer.MAX_VALUE;} This works so far fine. Propably we do
not need
any code change. This is maybe even better, because than DataView
respects the contract that it does not give a count paramter to
iterator() where
first+count is bigger than what size() returned. Anyway
I'll take a
first+look
and maybe I should write a test-case for that.

Alright, if that's what you guys want :) I will make
the changes
to make it work with model.equals(model). I am also
going to get
rid of the uniquekeyprovider since the model comparison
makes it
obsolete.
I will tag the current version with

Initially I was not sure (anymore), but after reading
Phil's comment I
also think model.equals(model) is better. I also think the
identity definition (wheter through equals or string
uniquekey)
belongs to the
data side, because you can only do this with knowledge
about the data.
And I belief that it can save you some typing if you
have it all
in one place.
I strongly agree that there should be a property on
DataView to turn
OIR on or off.
BTW: Does DataView need to call IDataProvider.size().
Wouldn't it be enough if it just called iterator() with
viewSize. The
iterator just returns than what is there. I have quite some
views (unfortunately
orderitems) where I do not need paging and can just
get all of
them with one select .

when row equality is available, which it always will be in
this case.
I think if you want to make it more general, use the
model's equals so
that it can use value, row, or object identity. I don't
think that
requiring a proper implementation of equals on the model is
any different from requiring it on the object and
it gives you
more options.

Re: [Wicket-user] New Wiki Page
That depends a bit how many pages you create on the run.
Because we fill a PageMap of which you can set the max number of pages
in ApplicationSettings:
/**
* Gets the maximum number of pages held in a session.
*
* @return Returns the maxPages.
* @see ApplicationSettings#setMaxPages(int)
*/
public final int getMaxPages()
{
return maxPages;
}
default is 10
So the last 10 pages you create (instances of! so 10times a
MyPage1.class also counts as one page)
If you want much lower then you can specify that but do remember that
the back button support depends a bit on this
to lookup old pages..
Also ofcourse you can hold you're self pages in mem if you keep
references to it through for example PageLinks that can
hold instances of pages that a link will set as the current when the
link was clicked on

So that all those objects aren't kept in mem.\
Great, that's what I had hoped (and read from the docs) so it's good
to get confirmation. :)
Now my question is, what is the lifespan of the Page object instance?
How long does that live?

Re: [Wicket-user] New Wiki Page
Johan, Thanks for the helpful answer. I come from a Spring MVC (and Struts before that) world of request/responses, so I'm mapping what I know to the world of Pages. So far, so good. :) So the last 10 pages you create (instances of! so 10times a MyPage1.class also counts as one page) Right, this makes sense. In other words, each use has their own instance of a Page class (one and only one instance per user). Would that be correct? With detachable models, we're able to bind the backing model object for just the scope of the request. Is there anything analogous for Page instances? Since Pages are stored in the HTTP Session, can we attach/detach Page classes as well?

I was acutally thinking along the lines of implementing a
PageableOrderedRepeatingView and than nest another
OrderedRepeatingView.
What about having a default PageableOrderedRepeatingView -
glad there is autocompletition - which has a method
internalOnBeginRequest(int page, int startIndex, int size),
so you could do the above and maybe other things more easy by

Subject: [Wicket-user] PageableDataView and column cells
Hi,
I'm trying to display a grid of images, for example 4
columns and 3
rows of images, where each cell is a different entry
retrieved from
the database with a different index/id.
I took a look at the DisplayTag example and
PageableDataView's
source-code and they don't seem to be quite appropriate
for handling
my use-case. In a nutshell, PageableDataView only has a
concept of
rows, where the
populateItem(ListView) method allows one to add()
different views of
the same database row. So for example, a given row will
have an id,
name, description, etc...
What I need is multiple columns per visual row where
each column is
a distinct DB item, with a distinct ID.
PageableDataView only increments the index outside the scope of
populateItem() so I'm not sure it's possible to implement
using it.
My gut feeling is that maybe I can use PageableDataView
with CSS
somehow to emulate columns but i would be much nicer if I
just had a
component that had the concept of columns in the first place.
What do you think?
Thank you,
Gili

The purpose of it is this: I am writing a booking application and every trip can have a variable number of little extras that you can book on top of the main trip (a special dinner, a boat ride and so on). Each one of those extras can be booked in different categories and different roomtypes (if the guest has to stay over night). So it might look something like this: DDC = DropDownChoice for Category DDR = DropDownChoice for Roomtype Homer Lenny Carl Chinese DinnerDDC, DDRDDC, DDRDDC, DDR Boat Trip DDC, DDRDDC, DDR DDC, DDR Visit to the Powerplant DDC, DDRDDC, DDRDDC, DDR I have a list of POJOs for the customers and I have a list of POJOs for the extras. Oh, and the booking of these extras is optional, of course.

Nest two listviews.
Wicket allows you to do so:

/table
add(new ListView(rows, rowsList) {
public void populateItem(ListItem row) {

Re: [Wicket-user] Multiple checkboxes, table columns how-to in Wicket?
First a Form. The a ListView. And for each row a Label and a CheckBox

have no problems there.
Doesn't that work for you?

I've got a list of Services, with basically a String ('name') and a

display them as checkboxes in a set of columns. The QD JSP method
puts them in a table, with a set of checkboxes making up a column in a
td.../td, as below...
String generateServiceTable(List services, int colSize, String
listName) {
int cols = (services.size() / colSize) + 1;
StringBuffer sb = new StringBuffer();
sb.append(table tr\n);
int rows = 0;

Service service = (Service) services.get(i);

sb.append(td valign=top width=\ + 100 / cols +

}
rows++;
sb.append(input type=\checkbox\ name=\ + listName +

sb.append(service.getName());
sb.append(\);
if (service.isFree()) {
sb.append( checked);
}
sb.append();
sb.append(service.getName());

if (rows == colSize) {
sb.append(/td\n);
rows = 0;
}
}
sb.append(/tr\n);
sb.append(/table\n);
return sb.toString();
}
so I get a
a1[] a11[] a21[] a31[] ...
a2[] a12[] a22[] a32[] ...
...
a10[] a20[] a30[] a40[] ...
effect, but I'm having difficulty working out a good/clean/simple way
of achieving the same result with Wicket.
(Note that using the same name on the checkboxes results in them
behaving in the same way as a multiple-choice list does, in terms of
what the browser dispatches, at least.)
I had this all working happily, using a ListMultipleChoice, so I've
got the 'surrounding' form/model, etc, it's just how best to do this
that's unclear...

Re: [Wicket-user] Re: ColumnedDataProvider startIndex problems
I actually like both of your approaches (who wonders chief of table with chief of DataView :). Like Igor says it is definately better to have components which have it all in one piece nicely together. On the other hand Phil's ColumnDataProvider has it's elegancy. It does not span an extra hierarchy and is IMO more flexible. I was actually thinking of a TableModelDataProvider which has an abstract method IModel getModel(int row,int col) - useful for calculated things or tables with a lot of empty elements. Of my head: Why not combine both approaches? Have a generified DataTable (TableView) which uses for the rows an DataView and mainly has a method populateDataItem(DataItem di, int col, int row). Than make special panels which use this generic TableView and automatically wrap the IDataProviders in sepcialized providers or demand differnt models or whatsoever. Christian PS: The only reason for the offset I can think of is that you might want to start with an element which by the current calculation lies in the middle of a row.

RE: [Wicket-user] Re: ColumnedDataProvider startIndex problems
How about this idea:
We have a gridview extends dataview. A gridview takes a render interface
that it uses to render the grid (instead of body markup), so we can have a
tablerenderer or cssrenderer or whatever, and the interface would roughly
look like this:
Interface IGridRenderer {
begin(GridView view);
beginRow(GridView view);
beginCell(GridView view);
endCell(GridView view);
endRow(GridView view);
end(GridView view);
}
Basically this is the same as my first post that inserted the html directly
but now its tucked away in a renderer. This way we don't have the
unnceessary row-wise views and you can even use OIR cleanly since it is
basically a dataview.

Re: [Wicket-user] Multiple checkboxes, table columns how-to in Wicket?
I don't think so, or at least it's the step beyond that that I'm not
seeing. My tries with a ListView gave me a repeated set of
tditem/td blocks, (using a Label for the item), but I can't see
how I can generate something like:-
td
item1br
item2br
..
item10br
/tdtd
item11br
item12br
..
/td
I think that if the original 1-row format isn't kept, I might be able
to do something similar, where the key might be to explicitly re-map
the input list into a list of 'horizontal' lists, then use a series of
tr's enclosing td's, each enclosing a single item, but that didn't
seem to be all that simple/clean and I wondered if I was missing
something obvious... (Maybe I need to investigate extending
ListMultipleChoice or it's parent, and see where that gets me.)

Re: [Wicket-user] RE: DataView.setStartIndex() (Igor Vaynberg)
Well, in my case, the underlying data is static. Images are not going
to be dynamically removed. If an exception is thrown, I wish for it to
be fatal. I'm just trying to mirror the design in Hibernate: you can
choose to catch StaleObjectStateException or not. Either way, it only
rarely gets thrown if the underlying data may change and if the data
can't be change it never gets thrown.
The reason you want to force developers to catch it is because it
usually indicates the original request is no longer valid. That is, if
the user operated on data which has been changed or removed then he
should be reprompted for input because there is no graceful way to
recover. Using my image browsing gallery as an example, say the user
clicks next to move to the next page in the set of images, and we find
out some images were removed, in *my* implementation I would catch the
exception, find out what the last image is and ensure that the user sees
the last page because that's what he meant to do... move forward, not back.
I really think this is a domain-specific thing. You can't know ahead of
time what the developers will want to do.

Im not sure this is a good idea. For example, when using
pageabledataview lets say at the time of request 1 you have
4 pages so
the navigator will draw 4 links, use clicks page 4 and at that time
there are only 3 pages because some rows were deleted. In this
situation would you like to deal with the exception or just let the
listview default back to first page and only draw 3
navigation links?
When the new navigation is done we can make it smarter and
based on the index default ot the first or last page.
Well, if the user wishes to catch the exception and
redirect to index zero instead that's his choice to make but
right now we're not even giving people the choice.

Re: [Wicket-user] Multiple checkboxes, table columns how-to in Wicket?
td
item1br item2br
/td
could be done just with a listview too:
td
span wicket:id=listspan wicket:id=label /br/span
/td
those spans shouldn't be in your way, and you could even set the
rendering of the tags off.
And you can nest listview as deep as you want.
But I probably don't understand what you mean? :)

td
item1br
item2br

item10br
/tdtd
item11br
item12br

I think that if the original 1-row format isn't kept, I might be able
to do something similar, where the key might be to explicitly re-map
the input list into a list of 'horizontal' lists, then use a series of
tr's enclosing td's, each enclosing a single item, but that didn't
seem to be all that simple/clean and I wondered if I was missing
something obvious... (Maybe I need to investigate extending
ListMultipleChoice or it's parent, and see where that gets me.)

Hi,
I'm currently trying to 'mirror' a quick dirty JSP page in Wicket
wondering how best do a particular thing...
I've got a list of Services, with basically a String ('name') and a
boolean attribute ('free'). There are 90-odd of these, and I need to
display them as checkboxes in a set of columns. The QD JSP method
puts them in a table, with a set of checkboxes making up a column in a
td.../td, as below...
String generateServiceTable(List services, int colSize, String
listName) {
int cols = (services.size() / colSize) + 1;
StringBuffer sb = new StringBuffer();
sb.append(table tr\n);
int rows = 0;
for (int i = 0, ; i services.size(); i++) {
Service service = (Service) services.get(i);
if (rows == 0) {
sb.append(td valign=top width=\ + 100 / cols +
%\\n);
}
rows++;
sb.append(input type=\checkbox\ name=\ + listName +
\ value=\);
sb.append(service.getName());
sb.append(\);
if (service.isFree()) {
sb.append( checked);
}
sb.append();
sb.append(service.getName());
sb.append(br\n);
if (rows == colSize) {
sb.append(/td\n);
rows = 0;
}
}
sb.append(/tr\n);
sb.append(/table\n);
return sb.toString();
}
so I get a
a1[] a11[] a21[] a31[] ...
a2[] a12[] a22[] a32[] ...
...
a10[] a20[] a30[] a40[] ...
effect, but I'm having difficulty working out a good/clean/simple way
of achieving the same result with Wicket.
(Note that using the same name on the checkboxes results in them
behaving in the same way as a multiple-choice list does, in terms of
what the browser dispatches, at least.)
I had this all working happily, using a ListMultipleChoice, so I've
got the 'surrounding' form/model, etc, it's just how best to do this
that's unclear...

RE: [Wicket-user] Re: ColumnedDataProvider startIndex problems
Looks ok I think although I'm not too familiar with this whole concept
of a seperate renderer. I'd have to try it to see what I think :)
Gili
How about this idea:
We have a gridview extends dataview. A gridview takes a render interface
that it uses to render the grid (instead of body markup), so we can have a
tablerenderer or cssrenderer or whatever, and the interface would roughly
look like this:
Interface IGridRenderer {
begin(GridView view);
beginRow(GridView view);
beginCell(GridView view);
endCell(GridView view);
endRow(GridView view);
end(GridView view);
}
Basically this is the same as my first post that inserted the html directly
but now its tucked away in a renderer. This way we don't have the
unnceessary row-wise views and you can even use OIR cleanly since it is
basically a dataview.

Well as I said when the new paging impl is done dataview will be able to
smartly move forward as opposed to always moving backward.
Meanwhile override the setfirstindex to throw the exception. I don't think
this functionality belongs in dataview.

Well, in my case, the underlying data is static. Images
are not going to be dynamically removed. If an exception is
thrown, I wish for it to be fatal. I'm just trying to mirror
the design in Hibernate: you can choose to catch
StaleObjectStateException or not. Either way, it only rarely
gets thrown if the underlying data may change and if the data
can't be change it never gets thrown.
The reason you want to force developers to catch it is
because it usually indicates the original request is no
longer valid. That is, if the user operated on data which has
been changed or removed then he should be reprompted for
input because there is no graceful way to recover. Using my
image browsing gallery as an example, say the user clicks
next to move to the next page in the set of images, and we
find out some images were removed, in *my* implementation I
would catch the exception, find out what the last image is
and ensure that the user sees the last page because that's
what he meant to do... move forward, not back.
I really think this is a domain-specific thing. You
can't know ahead of time what the developers will want to do.

Re: [Wicket-user] Re: ColumnedDataProvider startIndex problems
Implementation wise this is definately better, OIR - again -, base it on
DataView and no extra lines. If you can read the markup much better - I do
not want to have that in the code. To which extend can you add attribute
modifiers or other things you could add to a row dataItem?
Remains one thing with Phil's approach the Model has the final word on the
columns count as it has now with the rows. I think we should keep this in
parallel. Today there was this case with trip-booking where the column
count was only determined by the model. Maybe still accept lists or
collections in the iterator.
I think it also depends on paging Johan has asked there for some feedback.

I told you I didn't like it :) The whole process should
be smoother,
why cant the internal view simply get the iterator from the
external
view and use that. Why have a whole other wrapper/provider
to implement.
What is this offset? When using pageddataview you should
use the page
number to offset, when using a normal dataview you should
use setfirstindex().
-Igor
I also agree it's not as smooth as it should be, but I
also explained
in the previous email why
DataView.setFirstIndex() will not work. This should all be
refactored
into a new component that is column-aware instead of having to use
ColumnedDataProvider like we do now. I don't think there is
a cleaner
way.

Re: [Wicket-user] PageableDataView and column cells
Thanks,
I can not realy help you. I just browsed the discussion and I am not sure
how the interface should look like:
Is it:
getCurrentPage()
setCurrentPage(int)
getPageCount()
or should there be more in it?
For example the setNumberOfRows on a PageableListView or ListView (if we
combine them)
who is calling that. Are we going to push it through a Navigator or are
users want to set them directly on the listview...
As far as I understand the paging should be general useable and than ie a
wizard has just one 'row' per page. So I think it realy depends on the
component which shows the rows and therefore the numberOfRows should be
set there, if it makes sense at all.
As said I know too little about it and certainly do not want to open this
discussion again.

Wow, that's a good one. I guess there are also others who
need it and facing the implementation (I couldn't have done

I was acutally thinking along the lines of implementing a
PageableOrderedRepeatingView and than nest another
OrderedRepeatingView.
What about having a default PageableOrderedRepeatingView -
glad there is autocompletition - which has a method
internalOnBeginRequest(int page, int startIndex, int size),
so you could do the above and maybe other things more easy by
hand. I don't have a real use-case - just a thought.

Subject: [Wicket-user] PageableDataView and column cells
Hi,
I'm trying to display a grid of images, for example 4
columns and 3
rows of images, where each cell is a different entry
retrieved from
the database with a different index/id.
I took a look at the DisplayTag example and
PageableDataView's
source-code and they don't seem to be quite appropriate
for handling
my use-case. In a nutshell, PageableDataView only has a concept
of
rows, where the
populateItem(ListView) method allows one to add()
different views of
the same database row. So for example, a given row will
have an id,
name, description, etc...
What I need is multiple columns per visual row where
each column is
a distinct DB item, with a distinct ID.
PageableDataView only increments the index outside the scope of
populateItem() so I'm not sure
Re: [Wicket-user] Re: ColumnedDataProvider startIndex problems
Looks bad :)
We should have external markup files (i.e. *.html) instead of doing
this the old servlet/JSP way of manually writing out HTML.

How about this idea:
We have a gridview extends dataview. A gridview takes a render
interface that it uses to render the grid (instead of body
markup), so
we can have a tablerenderer or cssrenderer or whatever, and the
interface would roughly look like this:
Interface IGridRenderer {
begin(GridView view);
beginRow(GridView view);
beginCell(GridView view);
endCell(GridView view);
endRow(GridView view);
end(GridView view);
}
Basically this is the same as my first post that inserted the html
directly but now its tucked away in a renderer. This way we
don't have

Wow cool. And if I'd want my 'traditional' approach I could maybe even add
a renderer which makes DataViews per row?

RE: [Wicket-user] Re: ColumnedDataProvider startIndex problems
There are plenty of components in wicket that write out html directly to the
response stream, sometimes it is the best and easiest solution.
In this case all we are interested in is generating a simple grid layout
that hosts cells. Is it easier to write your own renderer to customize your
css or whatever as opposed to having to write markup for two dataviews
everytime and making sure you get that exactly right.
With a renderer all you do is:
table wicket:id=grid cellspacing=0 cellpadding=2
[cell markup]
/table
Anyways, if you don't like it I wont implement it until I need it :)

[Wicket-user] Spiral 12
Hi, I have a new version of the Urls application (Spiral 12 = urls12) that uses a tree. Thanks to Eelco for making it possible. Some interesting features: Categories of urls can now be browsed within a tree with expandable and shrinkable nodes (Home:Categories Tree). A member may now select a category of interest in the categories nested list simply by checking a category box (Home:Members:Interests). Urls: Spiral 12 introduction:: http://drdb.fsa.ulaval.ca/urls/web/spirals/spiral12/index.html Spiral 12 in action: http://drdb.fsa.ulaval.ca/urls12/app Spiral 12 zip file: http://drdb.fsa.ulaval.ca/urls/web/zip/urls12.zip While testing the application I have discovered some strange things that I cannot explain. CategoriesPage: A category removal produces an exception (but it removes the member) ?! Caused by: java.lang.NullPointerException at wicket.Component.setResponsePage(Component.java:1214) at org.wicket.urls.app.view.category.CategoriesPage.update(CategoriesPage.java:156) at java.util.Observable.notifyObservers(Observable.java:142) Corrected in CategoriesPage by: // NullPointerException in removal // setResponsePage(new CategoriesPage(parentCategory)); Page categoriesPage = new CategoriesPage(parentCategory); categoriesPage.onRedirect(); NewMemberPage: After registering as a new member, the login is shown and not the home page (HomePage) ?! If you login, the registration form is shown again with empty fields and validation errors. Use the Home link to leave the form (you have been already logged in). If you are confused (as I am with the reason for this), login as a regular member (dr, dr) or an administrator (admin, admin).

Re: [Wicket-user] Re: ColumnedDataProvider startIndex problems
Why can't we just do this?
table wicket:id=grid cellspacing=0 cellpadding=2
tr wicket:id=row
td wicket:id=columncell/td
/tr
/table
I mean, this way you don't need special renderers (you just put all
your stuff directly into the HTML file) and you can still do either old
HTML tables or CSS or whatever. We allow developers to attach three IDs
on the markup end (one for the grid, one for the row, one for the
column) and they can use any tags (i.e. table, tr, td, div, span, etc)
and put any markup before or after them.
Wouldn't this work?

RE: [Wicket-user] Re: ColumnedDataProvider startIndex problems
This is how it works with the columned data provider isnt it? The problem is
that there is an impedence mismatch between the idataprovider which provides
a flat list and the double dataview which tries to fit the flat list into a
grid. The renderer imho fixes that.
Anyways, as I said, no point further discussing this if the current approach
works for you.

Re: [Wicket-user] Re: ColumnedDataProvider startIndex problems
I like the render idea. Maybe you could render in internalOnBeginRequest()
and realy make a Renderer for lists of dataitems. For a renderer which
produces the html in code I think you could just record the strings and
render them onRender and for a DataViewInDataView renderer just behave
like always. Maybe with a bit of changing the renderer interface this
could work?
Anyway it is quite late and thanks,

Re: [Wicket-user] Re: ColumnedDataProvider startIndex problems
The current mechanism works, but it is not elegant. I really don't
understand what impedence mismatch you're talking about though. We take
the flat list and divide it into columns and rows, much like we're
already doing using ColumnedDataProvider -- but all in one component
instead of across multiple ones.
Off the top of my head, I would take the DataViewer and add the concept
of columns into it and I think that would be pretty elegant. No?

Why can't we just do this?
table wicket:id=grid cellspacing=0 cellpadding=2
tr wicket:id=row
td wicket:id=columncell/td
/tr
/table
I mean, this way you don't need special renderers (you
just put all your stuff directly into the HTML file) and you
can still do either old HTML tables or CSS or whatever. We
allow developers to attach three IDs on the markup end (one
for the grid, one for the row, one for the
column) and they can use any tags (i.e. table, tr, td, div,
span, etc) and put any markup before or after them.
Wouldn't this work?

How about this idea:
We have a gridview extends dataview. A gridview takes a render
interface that it uses to render the grid (instead of body
markup), so
we can have a tablerenderer or cssrenderer or whatever, and the
interface would roughly look like this:
Interface IGridRenderer {
begin(GridView view);
beginRow(GridView view);
beginCell(GridView view);
endCell(GridView view);
endRow(GridView view);
end(GridView view);
}
Basically this is the same as my first post that
inserted the html
directly but now its tucked away in a renderer. This way we
don't have
the unnceessary row-wise views and you can even use OIR
cleanly since
it is basically a dataview.

Re: [Wicket-user] Multiple checkboxes, table columns how-to in Wicket?
Well, there's one (partial) solution like this
Html:
table
tr
span wicket:id=freeServices
td valign=top width=10%
span wicket:id=cols
input type=checkbox
wicket:id=checks/span wicket:id=labelsDummy Item/spanbr/
/span
/td
/span
/tr
/table
Java:
int colSize = 10;
List checkboxes = new ArrayList(), column = new ArrayList();
for (int i = 0; i services.size(); i++) {
column.add((Service) services.get(i));
if ((i+1) % colSize == 0) {
checkboxes.add(column);
column = new ArrayList();
}
}
if (!column.isEmpty()) {
checkboxes.add(column);
}
add(new ListView(freeServices, checkboxes) {
public void populateItem(final ListItem col) {
List column = (List) col.getModelObject();
col.add(new ListView(cols, column) {
protected void populateItem(final ListItem item) {
Service service = (Service) item.getModelObject();
item.add(new Label(labels, service.getName()));
item.add(new CheckBox(checks, new
Model(String.valueOf(service.isFree();
}
});
}
});
But there are still a number of issues such as the way I have to(?)
use both a CheckBox and a Label (html value attribute should be
available, making the Label unneeded) and the way (which I've not yet
confirmed but suspect) that I'll need to deal with the results
individually, rather than en-masse, even before my own issues such as
the hard-coded HTML 10% needing making dynamic.
All of this suggests to me that there's an area of form support that
could do with a closer look, in that it looks to me as if there's some
core functionality missing with regards to CheckBoxes used in groups,
rather than individually.
(I don't know if I can come up with anything, but it'll at least give
me a purpose in trying to understand the internals of what's happening
in forms...)

those spans shouldn't be in your way, and you could even set the

And you can nest listview as deep as you want.

I think that if the original 1-row format isn't kept, I might be able

the input list into a list of 'horizontal' lists, then use a series of
tr's enclosing td's, each enclosing a single item, but that didn't
seem to be all that simple/clean and I wondered if I was missing
something obvious... (Maybe I need to investigate extending

Re: [Wicket-user] Re: ColumnedDataProvider startIndex problems
Actually, what I'd like to propose is actually going the other way. I
propose we replace all references to rows in PageableDataView with
cells. Here is what I have in mind:
Users can choose to insert as many or little columns per row (or rows at
all) as they wish and insert tr or td as they see fit. They
basically make use of the index of a DataItem (cell) to decide how to
render it.
The benefit of this approach is extra flexibility so it is possible to
implement tables where the first row contains one cell (i.e. the title)
then the next couple of rows contain four cells (adding up some items)
and then the final row contains two cells (total=, some value). This
is possible in HTML but not possible to express using PageableDataView.
While it is not used as frequently as fixed column/row layouts, I have
seen it often enough on web pages.
I think once you introduce the concept of rows into PageableDataView you
will get users who expect columns. Let's just avoid this entire
conversation by rephrasing the problem in terms of *cells* per page and
let the user decide on the layout.
I don't think this will result in much of a drop in ease-of-use but will
go very far in increasing flexibility. Anyway, I'm curious to know what
you think.

RE: [Wicket-user] DataView.clearCachedItemCount()
clearCachedItemCount() is part of an internal contract. I don't see why the
code you mentioned is part of the dataview. You can write a
LazyDataProviderDecorator that would implement the count() just like what
you described:
LazyDataProviderDecorator {
int count() {
if (delegate.count()==0) {
initializedelegate();
}
return delegate.count();
}
...
}
Does that make sense?

Hi Igor,
I'd like clearCachedItemCount() to become protected
(right now it is
private) because my code does the following:
- Check the number of images in the DataProvider
- If the image count is zero, it means we need to
lazily-initialize the image gallery (where the DataProvider
is reading from)
- Populate the gallery, reset the itemCount and continue ...
- Rendering process kicks in, it should see a non-zero value
for item count.
Is this a decent use-case? Are you fine with upgrading
accessibility to protected?

Right, getting at the underlying IDataProvider is a better solution.

Subject: [Wicket-user] DataView.clearCachedItemCount()
Hi Igor,
I'd like clearCachedItemCount() to become protected
(right now it is
private) because my code does the following:
- Check the number of images in the DataProvider
- If the image count is zero, it means we need to
lazily-initialize the image gallery (where the DataProvider
is reading from)
- Populate the gallery, reset the itemCount and continue ...
- Rendering process kicks in, it should see a non-zero value
for item count.
Is this a decent use-case? Are you fine with upgrading
accessibility to protected?
Thanks,
Gili

Re: [Wicket-user] Re: ColumnedDataProvider startIndex problems
sigh I said I disliked the idea of outputting HTML from Java code because this is very much like plain servlets or JSP, both of which are notoriously ugly doing this. Well anyway, if this component is fully theoretical, I guess I can't very well try it. How about this idea? div wicket:id=row div wicket:id=column cell data /div /div It would sort of work like ColumnedDataProvider did but cleaner. In the above example you'd have two instances of the same class (similar to ListView, I'm going to call it MyListView) that would share the same state information. So, allow me to walk you through the rendering process chronologically: 1) Construct MyListView for row, pass in IDataProvider into constructor 2) Construct MyListView for column, pass in row MyListView into constructor 3) Now, when populateItem() is invoked for either the row or column, the item's getIndex() will be shared among the two... what this means is that the index will be relative to the original IDataProvider, not relative to the MyListView passed into the constructor. populateItem() will be passed a DataItem for both row and column. See what I mean? It's very flexible in that you can nested multiple layers but at the same time the overall state is shared so you know what your actual index is. What do you think?

Re: [Wicket-user] Multiple checkboxes, table columns how-to in Wicket?
But there are still a number of issues such as the way I have to(?) use both a CheckBox and a Label (html value attribute should be available, making the Label unneeded) If you want that, work with AttributeModifiers or make you custom CheckBox class that renders the tag in the way you want. and the way (which I've not yet confirmed but suspect) that I'll need to deal with the results individually, rather than en-masse, even before my own issues such as the hard-coded HTML 10% needing making dynamic. No, that should be the beauty of it all, it can be fully automatic. Put the ListView with your checkboxes in a Form and it should all work automatically. Provide the ListView with a List where each object has a boolean property (with a getter and setter) you use with your checkboxes. For each list item, use e.g. a PropertyModel. Note that if you are using detachable models (e.g. your list), if you don't do anything in the form's submit method (like persisting your changes), the next time the list renders it will use the same old value, which could give you the idea nothing happened. All of this suggests to me that there's an area of form support that could do with a closer look, in that it looks to me as if there's some core functionality missing with regards to CheckBoxes used in groups, rather than individually. Any idea that makes Wicket better is welcome :) Eelco (I don't know if I can come up with anything, but it'll at least give me a purpose in trying to understand the internals of what's happening in forms...) /Gwyn --- SF.Net email is Sponsored by the Better Software Conference EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile Plan-Driven Development * Managing Projects Teams * Testing QA Security * Process Improvement Measurement * http://www.sqe.com/bsce5sf ___ Wicket-user mailing list Wicket-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wicket-user
