Re: Ajax Busy Indicator
And wait a minute, is the container in fact the indicator?
Yes!
@Override
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
tag.put(src,urlFor(AbstractDefaultAjaxBehavior.INDICATOR));
}
This part I didn't understand.
The html has just img src=# border=0
wicket:id=ajaxIndicator/ and that command will replace the src -
Wicket's default indicator image.
Wicket id is a different thing than the markup id. Probably
you need to override getMarkupId() to return that id.
Ok. This is probably where I have messed up.
Say I have img src=# border=0 wicket:id=ajaxIndicatorImage/
in my HTML and an AjaxIndicatorContainer extends WebMarkupContainer
for it as previously.
Now, how do I set up the markup-id if it is not the same as wicket-id
:) ? Anyone has done this exact same thing before in a similar manner
and coud post code?

Re: Monitoring Wicket using JAMon
Hi, I came up with two possible candidate methods to put in JAMon monitoring. The: 1. ISessionStore.onBeginRequest and ISessionStore.onEndRequest 2. RequestCycle.onBeginRequest and RequestCycle.onEndRequest. For now I choose to override the ISessionStore because that one is called before and after the RequestCycle methods. I want to check with you guys if this is the best option or not. Which one do you recommend? Is there maybe another candidate I overlooked?

(just an example) What I do not want is the indicator to take up extra space from where it does not belong (i.e., either immediate left or right side of the button). Say, I want the following layout: element Aelement BindicatorIconelement Cnew row/block element DajaxSubmitButtonelement Eelement F With css I cannot position the IndicatorAppender like that. It will only appear on either left or right side of the ajaxSubmitButton. What I want is to a) independently position the indicatorIcon and b) independently position the submitButton and c) activate the indicatorIcon with the submitbutton. ** Martin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Pagemap null is still locked by blah exception, help!! why does wicket have to lock the pagemap
If 1 page instance can be accessed by multiply threads we suddenly have to
have synchronize blocks all over the place
in our wicket code (especially the response area, rendering)
Also in the request phase where you can alter components and so on. Also
needs to be synched. (add/remove of components, behaviours or validatiors)
Even when i just quickly think about it, there are s many things that
can go horrible wrong.. that i even dont dare to start coding for that.
What you can do is post your search to a bookmarkable page. Those are not
locked because you create a new instance

the other way is as igor describes. do the search in a seperate thread.
If it really takes that long then you do know that browsers also can

time out after they don't get anything for a while?
If it really takes that long then you should build a page where people

the trade off is that if you have long running requests you should

Re: Embedding in Jetty without web.xml
Dont change wicket, it's fine :-) Actually I got this working without any web.xml or WEB-INF/ and it's possible! The things is: When you use the wicket filter you also need to add the DefaultServlet (or any servlet that is mapped to your wicket filter path) it looks like that in my AppLauncherJetty.class context.addServlet(DefaultServlet.class, /*) // or whatever you wicket filter path is in jetty a filter is just _decorating_ a request. but the request needs a _target_ which the DefaultServlet in that case is. otherwise you get a 404! even though wicket filter eventually does not call chain.doFilter(..) jetty still needs the servlet. Try and see. Regards Peter Am 30.01.2008 um 01:27 schrieb Eelco Hillenius: Actually, WicketFilter does try to read web.xml. See WicketFilter#init. You could file a feature request to let the framework be more lenient so that it doesn't fail when web.xml is not available. We can at least think about that. To solve your problem now, I suggest you make a copy of WicketFilter for your own purposes and rip the web.xml reading code out and get your filter path somewhere else.

What you can do is post your search to a bookmarkable page. Those are not

Simple edit form and models
Hi all, First of all I want to congratulate Wicket guys for their work. Until today I have developed applications based mainly on SWT/RCP and JSP/Servlets. Currently we are evaluating various frameworks in order to initiate a new project, which will expose many of our in-house developed system (SWT/RCP) functions through web. It seems that Wicket is very close to what we are looking for, because more or less we have the same logic in our gui applications. I am trying to create a common template for edit forms responsible to edit properties of a single pojo. In general, I want to have fool control over the synchronization between the form’s data and pojo’s fields. I am posting some simple code.

Re: Pagemap null is still locked by blah exception, help!! why does wicket have to lock the pagemap
what you have now is better - doing a search in a different thread -
because it doesnt bogged on servlet contains's threadpool.

Re: Simple edit form and models
First of all I want to congratulate Wicket guys for their work.
Until today I have developed applications based mainly on SWT/RCP and
JSP/Servlets.
Currently we are evaluating various frameworks in order to initiate a new
project, which will expose many of our in-house developed system (SWT/RCP)
functions through web.
It seems that Wicket is very close to what we are looking for, because more
or less we have the same logic in our gui applications.
I am trying to create a common template for edit forms responsible to edit
properties of a single pojo. In general, I want to have fool control over
the synchronization between the form’s data and pojo’s fields.
I am posting some simple code.
I would appreciate if anyone has the time to take a look and tell me if I am
following a right approach about the models and the binding technique.
Out of curiosity - what are you going to do that needs this fool control over the binding process? I find in most cases that using
CompoundPropertyModel for the whole form and overriding some fields with another PropertyModel for example is sufficient in almost every
usecase. I would do something like:
public class InputForm extends Form {
public InputForm(String id, IModel model) {
super(id, model);
add(new TextField(personCode));
add(new TextField(lastname));
add(new TextField(someSpecialField, new PropertyModel(someOtherObject,
fieldname));
add(new Button(save) {
@Override public void onSubmit() {
// Save
}
});
}
}
Wicket takes care of all the manual labour concerning binding you are used to
from RCP-programming, so why not just let it shine? :)
Is it too memory expensive to keep instances of pojos inside the form?
Does the session keeps information for all pages or just for the current
page?
Normally you supply the form with a IModel, and depending on the size/nature of the model object you would use a LoadableModel to avoid
saving the whole object when you move on from that page.
Wicket 1.3 now uses SecondLevelCacheSessionStore per default, and I think only the current page is in memory, and that subsequent pages are
saved off to disk, so normally you don't need to think about optimizing for memory usage unless you have a very special case on your hands.

the only caveat is if that image component for some reason has
setoutputmarkupid(true) set on it, in which case the id attr you put

you would
final Image image=new Image(ajxIndicatorImage, ...);

pass that markup id to your iajaxindicatorware component

Custom components which accept multiple models
I'm writing an settings admin page for editing a bunch of Boolean
settings. I'm using a custom component to edit the boolean values.
This custom component needs access to two settings objects
(masterSettings, customSettings) to determine if a custom setting is
overridden by a master setting.
some pseudocode:
public class SettingsEditPage extends WebPage {
public SettingsEditPage(Settings masterSettings, Settings
customSettings) {
Model masterModel = new CompoundPropertyModel(new
LoadableDetachableModel(masterSettings){/* load method omitted */});
Model cutomModel = new CompoundPropertyModel(new
LoadableDetachableModel(customSettings){/* load method omitted */});
//
add(new SettingsEditComponent(canDeleteWidgets, masterModel,
customModel));
add(new SettingsEditComponent(canCreateWidgets, masterModel,
customModel));
add(new SettingsEditComponent(allowsReturns, masterModel,
customModel));
}
}
I'd like to use the component id for the SettingsEditComponent as a
property expression, like in a CompoundPropertyModel. This would be
used to query the master settings first. If that returns null, use
the value from the custom settings. I also need the ability to
display to the user whether a value came from the masterSettings or
customSettings.
It's not clear to me what the best way to architect this is.
Should I make a custom model that wraps both the masterSettings and
customSettings objects? It would need a boolean method to determine
whether a given propertyExpression is taken from the master or custom
settings. If I do this, the SettingsEditComponent constructor would
need to only accept that specific model type (or an interface with
the boolean method, which is overkill).
Or, should I pass both settings objects into the
SettingsEditComponent, as pictured above? It seems like it would be
harder to have detachable models in this case (I guess I'd just need
to override detatchModels()).
Or, some other option that I'm missing...
Thanks!

Re: Custom components which accept multiple models
you can make a model that wraps both and returns result { boolean
master, object value }
then you bind your textfield with (setting.value) and your
checkbox/flag with setting.master

Sorting using a DataTable
Hello,
I am using a SortableDataProvider with a DefaultDataTable.
From my understanding, it seems that for every column that I wish to sort
on, I need to add code to the iterator method of the
data provider. None of the columns were sorting and when I added some code
in the iterator method (see below) I was able to sort on the street column.
Is this the best way to sort columns? I am using wicket 1.3.
Thanks Karen
iterator method from a SortableDataProvider
public Iterator iterator( int first, int count ){
final SortParam sp = getSort();
EventList list = getInterruptionList();
if ( sp.getProperty().equals(street) ){
Collections.sort(list, new Comparator()
{
public int compare(Object arg0, Object arg1){
if ( sp.isAscending() )
return
((Interrupt)arg0).getStreet().compareTo(((Interrupt)arg1).getStreet());
else
return
((Interrupt)arg1).getStreet().compareTo(((Interrupt)arg0).getStreet());
}
});
}
return list.listIterator( first );

Why are new sessions created until wicket form
Why are new sessions created until wicket finds a form? I have a Session subclass that has a field clicks. On page A I grab the session and show the number of clicks. Everytime I refresh the click count is 0, and the newSession method is called in WebApplication. add(new Label(clickCount, ((HelloSession)getSession()).getClickCount())); getClickCount() return clicks++; If I head to page B that has a form on it the session sticks, and my click count starts to increment and the calls to newSession end. So my question is, why is newSession called repeatedly until I hit a form and how do I change this behavior (or am I missing something fundamental here) Thanks, Damian - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Ajax Busy Indicator
no, you dont need to extend an ajaxbutton, IAjaxIndicatorAware works on any component that has any kind of ajax behavior added to it This means? I tried using AjaxButton and adding an AjaxFormSubmitBehavior implements IAjaxIndicatorAware but that never received the submit event. I also tried a SubmitLink button with the same behavior, but it did not work. Finally, extending AjaxButton and implementing IAjaxIndicatorAware received the event, but lost the feedback functionality. I am still a bit clueless with this new frame ;) So how whould you have done it exactly right? t. Martin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Feedback Panel and Ajax Busy Indicator
and please rename arg0 to target :) It's a good idea to attach
Wicket sources to your IDE (e.g. mvn -DdownloadSources=true eclipse:eclipse)
because then this tends to happen automatically.
I have been thinking of attaching the sources... I found some example
of adding all sources of all packages in the repository. Is there a
way to limit this to e.g., specific packages? This way I can lazy-load
the sources whenever needed. And does it require some additional setup
from Eclipse (e.g., pom.xml/project properties) or will it
automatically find the existing sources from maven repository?
add(new FeedbackPanel(feedback));
Change this to
add(new FeedbackPanel(feedback).setOutputPlaceHolderTag(true));
I will try these and comment.
/**
* This method TODO
*/
...and it would be a good idea to cleanup code formatting
and remove these comments...
I prefer to comment all non-private members and the template gives me a TODO...
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
...and fix the exception handling, throw new RuntimeException(e);
Relax, it's just mock-up-code, but yes, I completely agree with you on this ;)

Re: Sorting using a DataTable
usually sorting is done in the database. if you get that list outside
the database, then yes, you have to sort it using your own
comparators.

Hello,
I am using a SortableDataProvider with a DefaultDataTable.
From my understanding, it seems that for every column that I wish to sort
on, I need to add code to the iterator method of the
data provider. None of the columns were sorting and when I added some code
in the iterator method (see below) I was able to sort on the street column.
Is this the best way to sort columns? I am using wicket 1.3.
Thanks Karen
iterator method from a SortableDataProvider
public Iterator iterator( int first, int count ){
final SortParam sp = getSort();
EventList list = getInterruptionList();
if ( sp.getProperty().equals(street) ){
Collections.sort(list, new Comparator()
{
public int compare(Object arg0, Object arg1){
if ( sp.isAscending() )
return
((Interrupt)arg0).getStreet().compareTo(((Interrupt)arg1).getStreet());
else
return
((Interrupt)arg1).getStreet().compareTo(((Interrupt)arg0).getStreet());
}
});
}
return list.listIterator( first );

is there wicket had per-defined the Thread for the form component
hi, for the above case, for example... my page constructor: i add the component ( modal window, feedBackPanel, form ) .

Re: Why are new sessions created until wicket form
your page is stateless because it just has a label on it. stateless pages do not create a session. if a stateless page is hit and no session is yet created wicket will create a fake session so that getsession() still returns something meaningful - but this session object will not be stored into the httpsession. your page that has a form on it is no longer stateless and thus needs to be stored in httpsession - so wicket persists its session into httpsession once that page is hit. if you want to force wicket to create session call getsession().bind(); -igor On Jan 30, 2008 7:01 PM, Damian Penney [EMAIL PROTECTED] wrote: Why are new sessions created until wicket finds a form?

Re: Ajax Busy Indicator
if ajaxbutton works for you thats great. i was simply trying to explain that iajaxindicatoraware is decoupled from ajaxbutton - it will work on any component to which you add an ajax behavior. -igor On Jan 30, 2008 9:04 PM, Martin Makundi [EMAIL PROTECTED] wrote: no, you dont need to extend an ajaxbutton, IAjaxIndicatorAware works on any component that has any kind of ajax behavior added to it This means?

Re: is there wicket had per-defined the Thread for the form component
the order in which you add components in java seldom matters, the true
ordering is defined by markup.

But here , i found the problem,...
In my page constructor, i defined the component modalWindow, feedbackPanel,

wish to auto pop up once the page is load ) first follow by the other. The
problem i faced here is the modal window run at the end once the page is
finish loaded. Cnan i know the reason here... ?
my page constructor :
public LineChart() {
/// modal window use panel..
add(modalWindow);
// to auto pop up the modal window.
ajaxLink = new AjaxLink(cancelReportModalLink){
@Override
public void onClick(AjaxRequestTarget target) {

add(feedback);
add(new LineChartForm(LineChartForm));
}
private class LineChartForm extends Form {
// execute query
// result as in JFreeChart
}
From the above partial code, the modal window should call then only form.
Can anyone give the explanation ?
and is it possible i stop the form process if the user click the cancel
button from the modal window ?
