Spring's AbstractMessageSource : read new label from DB

[Marieke Vandamme]

Hello, 

I don't know if my question is Spring related or wicket related, but i guess
it's wicket related so...
If not, my apologies, but please tell me so i can post my question to the
correct mailinglist.

I use the org.springframework.context.support.AbstractMessageSource to read
my labels from a database (in the method resolveCode I use my dao to get the
correct label). In the application-context, I use the bean with name
messageSource to link my AbstractMessageSource implementation in wicket.

Now my question:
The labels are only readed once from the database. They are cached somewhere
in wicket, i guess. But when deploying my application, most labels are not
translated yet. Is it possible to delete the cached labels somehow?

Thanks !

Re: Spring's AbstractMessageSource : read new label from DB

[Marieke Vandamme]

Hello again, 

maybe some more clarification why I guess this is wicket related. 
org.apache.wicket.resource.loader.IStringResourceLoader is the
implementation that is used in wicket to get the label from the DB, because
there the necessary function of the Spring MessageSource is called. The
function loadStringResource in IStringResourceLoader is only called once
for a label. Only when redeploying the application, the message is again
retreived with the loadStringResource. Is there any way to clear that
cache manually or something?
Thanks again !

Confused

[egolan74]

Hi,
I have a page that holds a list (of Strings).
In the constructor, I initialize the list.

Then I call a Panel with this list to create a ListView of something.
In a Modal window I set the list to have data in.

The problem is that the list is initialized whenever I refresh the page (F5)
(the Page's constructor is called).
How can I pass this problem.
Where should I keep a model that holds the list data?

Some code:
... Class members:
private ListString linksIds;
private final LinksPanel linksPanel;

... In the constructor:
super(id);
setOutputMarkupId(true);
linksIds = new LinkedListString();
...
linksPanel = new LinksPanel(links, getLinksIds());
...

The getters and setters:
public ListString getLinksIds() {
return linksIds;
}

public void setLinksIds(ListString linksIds) {
this.linksIds = linksIds;
linksPanel.setLinksByIds(linksIds);
}

The setter is called when the user press OK in a Modal window.
The list is changed and the UI changes Ajax-ly. So this is OK.
The only problem is refreshing the Page.

Thanks for any help,

Hi!

Here is a good example of a list model:

public abstract class AbstractListChoiceModelS extends
AbstractReadOnlyModelList? extends S {
  @Override
  public final ListS getObject() {
return getChoices();
  }

  public abstract ListS getChoices();
}

Now change your code as follows:

linksPanel = new LinksPanel(links, new AbstractListChoiceModelString() {
 @Override
 public ListString getChoices() {
   // Where did you get your choices in the first place?
 }
} );

Re: Regarding Loacale

[Wilhelmsen Tor Iver]

 When I, on the fly, change the language to something else 
 (de_CH), the Locale in my application is not changed.

Looking at Wicket 1.3 and 1.4 sources, the locale is picked up in the
Session constructor, so presumably you need to nuke the Wicket session
or let it expire before trying a new locale based on Accept-Language.

Re: wicket servlet mapping to subdirectory

[Thomas Lutz]

Thanks Igor !

I removed the filter init params, tried with a fresh 1.3.x from 
subversion, still did not work.


But :-), it's not wicket's fault, it's f* oc4j. The redirect after 
the login page (I am using the acegi+wicket approach from the wiki) is 
not handled right.. oc4j does a redirect with a relative url the wrong 
way, it's relative to the webapp context, but not including the servlet 
path.


I am playing around to find a workaround, if I am lucky I'll post the 
solution here, in case other unlucky oc4j users are out there :-).


Thanks again,
Tom

interesting

1) you can remove filter init params, when wicket servlet is used the
path can be determined from servletrequest
2) can you try with wicket-1.3.x branch to see if we have already fixed it
3) if its still broken file a jira issue

Hi again !

I've tried to solve my issue, but had no luck so far. Here is the web.xml
snippet I use:

I am not sure if I need the filterPath and filterMappingUrlPattern init
parameters, but I left them in.

My application is deployed with an application.xml containing

module
  web
web-uriACS.war/web-uri
context-rootACS/context-root
  /web
 /module

When I call http://ip:port/ACS/app/ I am redirected to

http://ip:port/ACS/;jsessionid=d5a0c3193157101e4c749c214a05985eb6afb0ce6bc9.e34RaxuNah4Rai0LahqTaNuRa34Te6fznA5Pp7ftolbGmkTy?wicket:bookmarkablePage=%3Aat.schnirkel.acs.MySignInPage

which of course does not work.

Mapping the servlet to /* works, but then my Acegi filter is not invoked,
because OC4J seems to ignore urls without a page in front of the ?,
although I've configured the filter with a /*

Any ideas on this ?

Thanks a lot,
Tom

My environment is OC4J, java 4 and wicket 1.3.3.

Hi !

No, sorry, maybe i was not precise enough, when i have the /app/* mapping,
i can access my HomePage directly, but all links from the HomePage as well
as the style sheet link and some image links (all within wicket:link) don't
work, as the /app/ part is missing. The only images working are the one
from the tree I use as menu.

Basically I don't need the /app/ subdirectory, but servlet filters in oc4j
seem to be rather buggy, and they are not called, if you don't have either a
page or a directory, just ip:port/context/?... does not work, as the filters
are not called.

So I tried to trick the filter (acegi) by adding a subdirectory... I
guess I have to add some filterPath or filterMappingPath flag to the
init-params of the servlet, but so far nothing worked. I'll dig into the
sources deeper tomorrow.

Thanks !

When you say I always get redirected to the root of the webapp, do you
mean when first trying to access your app, you have to go via a redirect

some such that takes you to http://www.mysite.com/; or similar?

This does not work, I always get redirected to the root of the webapp,

Is there any parameter I need to set to tell wicket about the different

Re: Confused

[egolan74]

Thanks Martin,
That really helped. Though I did something else and now I have a new
problem.
It's an Ajax problem now.

Here's what I did:
In the constructor:
idsModel = new LoadableDetachableModel() {
private static final long serialVersionUID = 1L;

@Override
protected Object load() {
ListString ids = new ArrayListString();
ListProperty properties =
sageDal.getPreference(userId, 
SETTINGS_GROUP,

HomePageSectionPanel.this.sectionId);
for (Property property : properties) {
ids.add(property.getValue());
}
return ids;
}

};

linksPanel = new LinksPanel(links, idsModel);

I am adding the ListView in LinksPanel:
private void init(final ListLinkContainer links) {
add(new LinksListView(listview, new AbstractReadOnlyModel() {
private static final long serialVersionUID = 1L;

@Override
public Object getObject() {
return links;
}

}));
}
(I have a method that changes the String ids to the LinkContainer).

My problem is when setting new list.
Here is my code:
public void setLinksIds(ListString linksIds) {
sageDal.setPreference(userId, SETTINGS_GROUP, sectionId,
linksIds.toArray(new String[0]));
}

It works and I actually see the change in the database. When refreshing (or
checking in the DB) I see changes.

BUT, it doesn't change automatically.
I use a ModalWindow and here's where I add my panel to the modal:
setWindowClosedCallback(new ModalWindow.WindowClosedCallback() {
private static final long serialVersionUID = 1L;

public void onClose(AjaxRequestTarget target) {
target.addComponent(homePageSectionPanel);
}
});

I'm sure I need to add something else somewhere.
But what? and where ?

Thanks,

Eyal

Re: Confused

OK, I'll try to explain.
1. I have a page that has a list of links.
2. The list is taken from the database the sageDal.getPreference(..) method
that I showed.
3. This list can be configured by the user.
4. I made a Modal window that shows the user all available links (also taken
from the DB).
5. When he selects the links he wants, he presses OK.
6. Then I update the DB. The sageDal.setPreference(...) method.

As for passing Objects.
I pass the model to the LinksPanel.
LinksPanel ha a ListView that uses a different AbstarctReadOnlyModel.

So my problem is that when I set the DB with new values, I need to inform
the Model (in the original panel) somehow that the DB was changed.

Re: Confused

[Martin Makundi]

Ok. I do not have experience with Modal windows in wicket, but do you
actually repaint the original page to even reflect the changes?

If you repaint it, and your model loads the data from DB, and the data
still does not show the changes (try to use breakpoints and debugger
to confirm this), you might have a problem with committing the changes
to your DB.

Hi everybody, this is my first post in the list.

I would like to ask for advice on the following topic: I am developing a
view with wicket, which contains a somewhat intensive logic behind. For
instance, when I select an option in a drop down choice, some fields are
disabled, while other fields are hidden, and when I select some radio
button, other set of fields get disabled or hidden, or are otherwise shown.

With disabled/enabled fields everything went alright, but when I started to
hide fields I discovered the following problem: if the initial situation
indicates that the field must be hidden, then the logic in the behaviors
tried to show them but it was not possible to do so, since the initial
markup never referenced those hidden fields (I discovered that with Ajax
Debug under Mozilla FireFox). It is important to say that, in the
AjaxRequestTarget, I was only adding the fields I changed. So a co-worker
told me I should add to the AjaxRequestTarget the panel or form where the
hidden/shown components lie (in my case it is the form) so they could be
correctly rendered. I tried it and, as he said, the logic started to work:
fields get hidden/shown properly everytime I choose the correct drop down
choices/radios.

But this brought me another problem: if I enter some text on the fields and
then activate one of these logics, all the fields are cleared. This is so
because the behaviors I was using (AjaxFormChoiceComponentUpdatingBehavior
for the radios and OnChangeAjaxBehavior for the drop down choices) do not
submit the form when activated. Since I now set the whole form in the
AjaxRequestTarget, this causes the data clear problem, because the model is
not updated at the time the logic executes, and then the whole form comes
back to the browser discarding the values entered by the user.

So, I made a fix by using AjaxFormSubmitBehavior (with some modifications
because I don't want validations to get executed when a radio button is
selected, for instance).
But the real question is: am I on the right way? perhaps the original
problem with the hidden fields could have been solved in another, more
standard way?

Any help will be really appreciated.
Best regards,
Andrés

Re: Confused

[Eyal Golan]

Well, my problem is more of an Ajax one (I think).
The database is changing.
I have a setter in my original Panel that is executed when the Modal is
pressed OK.
It stopped in the breakpoint.
I looked in the DB and saw the changes.
When pressing F5, I got the updated list.

So the problem is: how can I tell my Model (detachable) that there was
change in the database?
I also add the Panel (original) to the Ajax Target.

 Ok. I do not have experience with Modal windows in wicket, but do you
 actually repaint the original page to even reflect the changes?

 If you repaint it, and your model loads the data from DB, and the data
 still does not show the changes (try to use breakpoints and debugger
 to confirm this), you might have a problem with committing the changes
 to your DB.

  OK, I'll try to explain.
  1. I have a page that has a list of links.
  2. The list is taken from the database the sageDal.getPreference(..)
 method
  that I showed.
  3. This list can be configured by the user.
  4. I made a Modal window that shows the user all available links (also
 taken
  from the DB).
  5. When he selects the links he wants, he presses OK.
  6. Then I update the DB. The sageDal.setPreference(...) method.
 
  As for passing Objects.
  I pass the model to the LinksPanel.
  LinksPanel ha a ListView that uses a different AbstarctReadOnlyModel.
 
  So my problem is that when I set the DB with new values, I need to inform
  the Model (in the original panel) somehow that the DB was changed.

   Thanks Martin,
   That really helped. Though I did something else and now I have a new
   problem.
   It's an Ajax problem now.
  
   Here's what I did:
   In the constructor:
  idsModel = new LoadableDetachableModel() {
  private static final long serialVersionUID =
 1L;
  
  @Override
  protected Object load() {
  ListString ids = new
  ArrayListString();
  ListProperty properties =
  
   sageDal.getPreference(userId, SETTINGS_GROUP,
  
   HomePageSectionPanel.this.sectionId);
  for (Property property : properties) {
  ids.add(property.getValue());
  }
  return ids;
  }
  
  };
  
  linksPanel = new LinksPanel(links, idsModel);
  
   I am adding the ListView in LinksPanel:
  private void init(final ListLinkContainer links) {
  add(new LinksListView(listview, new
  AbstractReadOnlyModel() {
  private static final long serialVersionUID =
 1L;
  
  @Override
  public Object getObject() {
  return links;
  }
  
  }));
  }
   (I have a method that changes the String ids to the LinkContainer).
  
   My problem is when setting new list.
   Here is my code:
  public void setLinksIds(ListString linksIds) {
  sageDal.setPreference(userId, SETTINGS_GROUP,
 sectionId,
   linksIds.toArray(new String[0]));
  }
  
   It works and I actually see the change in the database. When
 refreshing
  (or
   checking in the DB) I see changes.
  
   BUT, it doesn't change automatically.
   I use a ModalWindow and here's where I add my panel to the modal:
  setWindowClosedCallback(new
  ModalWindow.WindowClosedCallback() {
  private static final long serialVersionUID =
 1L;
  
  public void onClose(AjaxRequestTarget target) {
  
  target.addComponent(homePageSectionPanel);
  }
  });
  
   I'm sure I need to add something else somewhere.
   But what? and where ?
  
   Thanks,

RE: Session end method

[Zappaterrini, Larry]

Ah, I see that now. I didn't dig deep enough. When I first started
working with Wicket sessions I was assuming (bad I know!) that
Session.invalidate would be called when the HttpSession timed out. I
noticed that it actually wasn't, so I then assumed (again!) that Wicket
wasn't handling any HttpSession time outs. Would it make sense to have
Wicket call Session.invalidate when the HttpSession times out to
simplify this use case and not require implementing ISessionStore?

 another approach is to simply output the javascript that uses the lib

 Ok,

 I understand your point and perhaps my whole setup is wrong. Here is my
 line
 of thinking:

 1. I have a component that needs some Javascript.
 2. The Javascript relies on an external library.
 3. There may be several instances of the component on the page.
 4. Other components on the page may have some Javascript as well and
  may also need the same library.
 5. I want to make sure that the library is loaded only once (which
  I can achieve nicely with a HeaderContributor)

 Is there some other way to handle this situation?

 maybe they add a javascript library via wickethead and have a

 point is its a bad idea to depend on the ordering, whichever way it

Re: Spring's AbstractMessageSource : read new label from DB

 Hello again,

 maybe some more clarification why I guess this is wicket related.
 org.apache.wicket.resource.loader.IStringResourceLoader is the

 there the necessary function of the Spring MessageSource is called. The
 function loadStringResource in IStringResourceLoader is only called once
 for a label. Only when redeploying the application, the message is again
 retreived with the loadStringResource. Is there any way to clear that

 I use the org.springframework.context.support.AbstractMessageSource to
 read my labels from a database (in the method resolveCode I use my dao to
 get the correct label). In the application-context, I use the bean with
 name messageSource to link my AbstractMessageSource implementation in
 wicket.

 Now my question:
 The labels are only readed once from the database. They are cached
 somewhere in wicket, i guess. But when deploying my application, most
 labels are not translated yet. Is it possible to delete the cached labels
 somehow?

Including wicket in JSPs?

[Jan . Koops]

Hello !

We are using a JSP-based content management system for navigation, page 
layout etc.
Now we're evaluating Wicket as our application framework: A Wicket 
application should appear in the center of the JSP based layout and 
navigation.
Has somebody already included a wicket page via jsp:include or other ways?
It seems to me a Page would be the wrong Wicket component to include, 
since no body or header should be rendered.

 Basically I don't need the /app/ subdirectory, but servlet filters in
 oc4j
 seem to be rather buggy, and they are not called, if you don't have
 either a

 are not called.

 So I tried to trick the filter (acegi) by adding a subdirectory... I
 guess I have to add some filterPath or filterMappingPath flag to the
 init-params of the servlet, but so far nothing worked. I'll dig into the

I guess the question really boils down to: where is the best place to

Re: Palette within a ModalWindow

[egolan74]

Hi,
Can you send a code example of how you have used the setContent ,
ModalWindow and Pallete all together?
I used the same as the examples of ModalWindow with a Page. And the Page has
the Pallete.
There aren't many examples of Palette.

Thanks,

Eyal

 Hi,
 
 I want to realize a palette within a ModalWindow. I have subclassed the

 actually, the model is updated with the selected choices after closing the

Re: Session end method

[Eyal Golan]

Regarding the cleaning Session issue.
Suppose I set expire time to very long time.
Suppose the user didn't log out, but just turned off the computer.
Is the Session still alive? Until it is expired?

If so, I guess I'll make a mechanism for using the same Session if the user
comes again.

Re: Confused

[Eyal Golan]

Got it!!
The problem was in the LinksPanel:
In the constructor I got the Model and did this:
final ListLinkContainer links = new ArrayListLinkContainer();
ListString linksIds = (ListString) linksIdsModel.getObject();
for (String linkId : linksIds) {
links.add(portalStructureManager.getLinkById(linkId));
}
init(links);

In init I created the ListView with an AbstractReadOnlyModel.

Instead, the fix is that the original model is THE SAME that is passed to
the list view.
Now, like magic, it works.
The only thing I need to do now (which is an application logic issue) is
casting the models.
It's not a Wicket issue anymore.

Thanks,

Eyal

Re: Including wicket in JSPs?

[jnorris]

Hi Jan,

I have a legacy home-grown jsp application where I'm showing wicket pages in
the content area using an inframe tag.  Initially I had a problem that
turned out to be caused by not using the closing tag for the iframe.  Here's
an example that works in IE6/7:

head
style type=text/css
iframe{ float:left; height:500px; width:100%; display:block;
frameborder:0;}
/style
/head

body
jsp:include page=/leftside.jsp flush=true /
jsp:include page=/top.jsp flush=true /
iframe src=http://someserver/WicketDemoPage?someparm=somevalue;
frameborder=0/iframe
jsp:include page=/bottom.jsp flush=true /
jsp:include page=/rightside.jsp flush=true /
/body

This technique works for me with bookmarkable pages, so in the above case
the following would be put in the init() method of the Application class: 
mountBookmarkablePage( /WicketDemoPage, WicketDemoPage.class );

HTH,
Jim

 Has somebody already included a wicket page via jsp:include or other ways?
 It seems to me a Page would be the wrong Wicket component to include, 
 since no body or header should be rendered.

Re: wicket servlet mapping to subdirectory

[Thomas Lutz]

I searched the list, but I guess nobody tried to map to a subdirectory 
so far... or combine it with acegi.


I've made some progress, though, basically the only solution yet was 
removing the filter, and handle the filter stuff in my customized wicket 
session. not very beautiful, but it works.


More detailed in case anybody has the same problem: I followed 
http://cwiki.apache.org/WICKET/acegi-and-wicket-auth-roles.html but 
removed HttpSessionContextIntegrationFilter and remebered the 
SecurityContext in the wicket session.


Thanks for your help, and thanks for this great framework,
Tom

Thanks Igor !

I removed the filter init params, tried with a fresh 1.3.x from subversion,
still did not work.

But :-), it's not wicket's fault, it's f* oc4j. The redirect after the
login page (I am using the acegi+wicket approach from the wiki) is not
handled right.. oc4j does a redirect with a relative url the wrong way, it's
relative to the webapp context, but not including the servlet path.

I am playing around to find a workaround, if I am lucky I'll post the
solution here, in case other unlucky oc4j users are out there :-).

Thanks again,

1) you can remove filter init params, when wicket servlet is used the

2) can you try with wicket-1.3.x branch to see if we have already fixed it

I am not sure if I need the filterPath and filterMappingUrlPattern init

My application is deployed with an application.xml containing

When I call http://ip:port/ACS/app/ I am redirected to

which of course does not work.

Mapping the servlet to /* works, but then my Acegi filter is not invoked,
because OC4J seems to ignore urls without a page in front of the ?,
although I've configured the filter with a /*

Any ideas on this ?

Thanks a lot,
Tom

My environment is OC4J, java 4 and wicket 1.3.3.

Hi !

No, sorry, maybe i was not precise enough, when i have the /app/*
mapping,
i can access my HomePage directly, but all links from the HomePage as
well
as the style sheet link and some image links (all within wicket:link)
don't
work, as the /app/ part is missing. The only images working are the
one
from the tree I use as menu.

Basically I don't need the /app/ subdirectory, but servlet filters in
oc4j
seem to be rather buggy, and they are not called, if you don't have
either a
page or a directory, just ip:port/context/?... does not work, as the
filters
are not called.

So I tried to trick the filter (acegi) by adding a subdirectory... I
guess I have to add some filterPath or filterMappingPath flag to the
init-params of the servlet, but so far nothing worked. I'll dig into the
sources deeper tomorrow.

RE: Session end method

[Zappaterrini, Larry]

Sorry, contains was too strong of a word. Let's say when the session is
invalidated that a heavyweight object contained in a global repository
must be freed. Come to think of it, even something as simple as logging
information about the session when it is invalidated fits this
description.

Re: Session end method

[Igor Vaynberg]

it is impossible to have this method on Session. session is stored
within httpsession and like i said, when that times out you can no
longer access its attributes - eg the Session object.

if you want to know when a session times out add httpsessionlistener
to your webapp.

PageableListView and Detachable Models

[Jürgen Lind]

Hi,

I a currently a bit stuck in dealing with a PageableListView and a detachable
model. I have build my own model that wraps a list of search results that should
exists as long as the page remains the same, i.e. across all requests that go
to the same page such as for navigation or sort actions. As soon as the page is
left, e.g. when the user navigates to the details page of a certain result,
the search result list is cleared.

However, it appears that the detach method is called immediately after the
PageableListView is rendered, i.e. at the end of each request. Is this
observation correct? And how would I deal with a requirement as described above?

Cheers,

J.

Re: PageableListView and Detachable Models

[Igor Vaynberg]

detach() is indeed called in the end of every request.

what exactly is your requirement? you want to run the query once, upon
page entry, and then always reuse the same resultset without doing
another query? in that case store the list of ids in your resultset as
a property of the page. the model of the listview can then retrieve
the subset of this list (based on the current page and number of items
needed) and do a select from foo where id in ( subset of id list )
query to retrieve the current window of data.

and min dates were. so if my user wanted to click back to say December 1950
could they? I know it is not very practical and I do not think this will
happen but I wanted to see how far back they could go and how far ahead they
could go.

relative location for css/javascript

[okrohne]

Hi,

I place my html files and css/javascript in different folders under the web
root dir:

/pages
/templates
/css
/javascript
/images

I use this structure outside the java packages as we use Adobe GoLive for
designing the pages.
I followed the Wiki suggestions to add resource folders and to use a
ResourceStreamLocator but the problem is that Wicket changes the relative
reference from ../css/styles.css to ../../css/styles.css , the same for
javascript/ images.

If I use absolute pathes like /css/styles.css then everthing works but I can
not see the html files properly in Adobe GoLive.

What do I wrong?
Can anyone explain me how to use relative pathes?


Thanks,
Oliver

This is indeed what I would like to do. However, my current approach is
to keep to  original result list in memory and do the paging on the list without
further database queries. I might try that option later, currently I am
doing some kind of exploration of how to do things in wicket to derive a
more or less generic architecture for our wicket projects.

DropDownChoice setting other DropDownChoice using AJAX results in null at submit

[Giuliano Caliari]

Hello,

I have a page in which there are 2 DropDownChoices. Both have to be set with an 
initial value.
The first DDC called  mapCategory is populated from a simple List.
The second DDC, chosenArmy is populated by a List of objects (Army) that 
can change, based on the value of the first DDC and other options. 
I used AJAX to change the value of the second DDC based on the first DDC.
In addition, the default value of the second DDC is also set when the user 
selects the value of the first DDC.
stwMatchPrefs is the property model set to the form.

When the user  sets the value on the first DDC, the value of the second DDC is 
set without problems, even the selected value is set correctly.
The problem is that if the user changes the value on the first DDC 
(mapCategory) and then submits, the value passed on the second DDC (chosenArmy) 
is always null, so the value received by stwMatchPrefs is null.
If the user submits without changing the value on the first DDC, everything 
work and the value of stwMatchPrefs is set correctly.
If the user changes the value on the first DDC (mapCategory) and then submits 
twice, the first time the value of chosenArmy is null, but the second submit 
has the right value.

Can anyone help me?
Thanks in advance.



Here's the page, with both DDC
I'm using wicket 1.3.3. Lines 57-65 have the AJAX code.

Re: PageableListView and Detachable Models

[Jürgen Lind]

Hi,

I am still a bit confused about one thing in the remark below: how can
the model of the list view return the required items? Should not the model
be unaware that it is used by a list view?

J.


in that case store the list of ids in your resultset as
a property of the page. the model of the listview can then retrieve
the subset of this list (based on the current page and number of items
needed) and do a select from foo where id in ( subset of id list )
query to retrieve the current window of data.

render PageParameters

[Scott Swank]

Is there code available to me to generate the the http get parameter
string that corresponds to a PageParameters instance?  I am generating
links from our confirmation e-mail back to bookmarkable pages in our
application.

Thank you,
Scott

Re: PageableListView and Detachable Models

[Igor Vaynberg]

the model can be aware that it is used by the listview. the separation
here is that the listview is unaware of where or how its list is
built.

for database stuff i prefer using dataview, it has database semantics
more closely built into it.

 in that case store the list of ids in your resultset as
 a property of the page. the model of the listview can then retrieve
 the subset of this list (based on the current page and number of items
 needed) and do a select from foo where id in ( subset of id list )
 query to retrieve the current window of data.

Re: PageableListView and Detachable Models

Ok, but since I pass the model into the constructor of the listview, how
is the model informed which part of the data to load? Is there a method
that I have been missing?

Re: PageableListView and Detachable Models

[Igor Vaynberg]

well, thats part of the problem with listview :)

see idataprovider and dataview

if you do want to use listview then you have to implement your own
List interface that loads windows of data at a time depending on which
get(index) is used.

Re: render PageParameters

[Jeremy Thomerson]

You could do something like:

WebRequestEncoder encoder = new WebRequestEncoder(new
AppendingStringBuffer(your-url));
for (Iterator it = parameters.entrySet().iterator(); it.hasNext(); )
{
Entry entry = (Entry) it.next();
encoder.addValue((String) entry.getKey(), (String)
entry.getValue());
}

I haven't tested that exact code, but basically this was taken from code in:
URIRequestTargetUrlCodingStrategy

Google friendly urls

[Mathias P.W Nilsson]

Hi!

I'm trying to get my wicket urls to work with google spiders. Right now I
have the ?wicket:interface=:1 and I was just wondering.

Do I have to use PageParameters to get urls like ?Brand=34 

I now pass objects to a pages constructor. Thanks

Like

ListItemFilter filters = new LinkedListItemFilter();
filters.add( new StoreFilter( 1 ) );
filters.add( new BalanceFilter( 1 ) );
filters.add( new BrandFilter( 34 ) );


setResponsePage( new ItemPage( filters ) ) ;

Re: Google friendly urls

[Igor Vaynberg]

setResponsePage( new ItemPage( filters ) ) ;

that wont work because it does not generate a bookmarkable url. you
have to encode filters in pageparameters and use bookmarkable page
links, such as:

add(new bookmarkablepagelink(ItemPage.class, filtersPageParameters));

you can also use StatelessLink/Form which also generate bookmarkable
urls and allow you to have onclick handlers.

pretty much. once you have to go this route you lose wicket's

Re: Google friendly urls

[Jeremy Thomerson]

Of course, you can make your code below significantly smaller by doing
something like (I haven't checked this code for 100% accuracy):

Long brandId = params.getLong(brand)
if (StringUtils.isEmpty(brandId) == false) {
brand = yourDao.getBrand(brandId);
}

You get the point - remove the big loop and just pull what you need from the
parameters.

How to create a cacheable image resource for a image file?

[Justin Morgan - Logic Sector]

In my web app there are a bunch of static image files that live  
outside the WAR in various places on the host's file system (also  
outside the purview of the httpd server too).  To serve up these  
images within my Wicket app, I've been reading their bytes via a File  
object and returning those bytes to an Image via a  
DynamicImageResource.  As usual, the Image is added to the page in the  
page's constructor.


This works great except for one problem...

Each time the user reloads the page, the HTML img gets a new src  
attribute because a new DynamicImageResource is created each time the  
page is instantiated.  Thus, the browser can't cache the image.  This  
is bad because I want the image to be cached.


My question is:  How can I provide a non-changing URL for the image  
resource so the image is cacheable?


Many thanks for any help.

 When the user  sets the value on the first DDC, the value of the second DDC

 The problem is that if the user changes the value on the first DDC

 (chosenArmy) is always null, so the value received by stwMatchPrefs is 
 null.

Hi, 

I haven't completely understood what is happening here, but 
will try to give some ideas below.

There is something strange happening with the models there.
Have you read the models wiki page? 

You could also try removing PropertyModel and 
CompoundPropertyModel usage for now, because they might 
obfuscate the problem.

IModel armyChoices = new AbstractReadOnlyModel()
{
public Object getObject()
{
ListArmy armys = new ArrayListArmy();
armys.add(stwData.getArmyByCategory(StwMapCategory.SMALL));
armys.add(stwData.getArmyByCategory(StwMapCategory.MEDIUM));
armys.add(stwData.getArmyByCategory(StwMapCategory.LARGE));

 stwMatchPrefs.setChosenArmy(stwData.getArmyByCategory(stwMatchPrefs.getMapCategory()));
return armys;
}
};

This seems like a strange side effect -- whenever a component
with armyChoices as its model is rendered, 
stwMatchPrefs.setChosenArmy() is called. Because this is the model 
of the chosenArmy DropDownChoice, whenever the DropDownChoice is 
rendered, this getObject() method is evaluated. But then again

 final DropDownChoice chosenArmy = new DropDownChoice(chosenArmy, 
 new PropertyModel(stwMatchPrefs, chosenArmy), armyChoices, 
 armyChoicesRenderer );
 chosenArmy.setOutputMarkupId(true);
 stwPrefsForm.add(chosenArmy);
 
 mapCategory.add(new AjaxFormComponentUpdatingBehavior(onchange)
 {
 protected void onUpdate(AjaxRequestTarget target)
 {
 
 stwMatchPrefs.setChosenArmy(stwData.getArmyByCategory(stwMatchPrefs.getMapCategory()));
 chosenArmy.setModelObject(stwMatchPrefs.getChosenArmy());
 target.addComponent(chosenArmy);
 }
 });
 }

Here you give a PropertyModel to chosenArmy DropDownChoice,
and it operates directly with the chosenArmy property of 
stwMatchPrefs. This means that the chosenArmy DropDownChoice 
selection and stwMatchPrefs.chosenArmy property are bound to
each other: when one changes, the other one changes as well.

In this light, it is absurd that you change both values in 
the onUpdate method. stwMatchPrefs.setChosenArmy() should be 
enough.

What is even stranger is that because of the armyChoices
model, stwMatchPres.setChosenArmy() is getting a competing 
call during rendering :)

 public ArmyServices getArmyServices() {
 return armyServices;
 }
 
 public void setArmyServices(ArmyServices armyServices) {
 this.armyServices = armyServices;
 }

BTW, what are these methods here for?

Best wishes,
Timo

generics

[Igor Vaynberg]

development of the 1.4 branch has been quiet lately, this is because
the core team has been busy working on an alternative way of
generifiing the framework. an early result of that effort can be found
here [1]. The key difference in [1] is that we have decoupled the
component from the type of the model.

here is the list of major differences:

(1) only components that use their model have a generic type
(components you are likely to call getmodel/getmodelobject on as a
user). so far these are link,form,formcomponent
subclasses,listview,listitem,(other repeaters will follow soon). this
allows for typesafety where it makes sense, and eliminates a ton of
noise from code. we will generify others upon request if a good
usecase is provided and we think it is widely applicable.

(2) non-generified components do not have IModelT get/setModel and T
get/setModelObject, instead they have IModel?get/setDefaultModel and
Object get/setDefaultModelObject. this clearly expresses that the
default component model is not tied to the type of component. this is
a bit of a pain from the code migration point of view, but we think is
worth the effort. generifyed components are free to implement the old
IModelT get/setModel, etc, but have to keep the unsafe cast inside.
see ListItem for an example.

basically we feel this is a much cleaner way then what is 1.4m2. this
is a call for confirmation/discussion from our user base. do try to
port a small project or a part of a larger project you are working on
to the [1] branch to see how the new api feels. if we do like this
more the new branch will be merged into what will be 1.4m3.
