Re: Redirect to HTTPS?
I haven't tested but I think the solution is to override public final CharSequence encode(final RequestCycle requestCycle,final IRequestTarget requestTarget)BUT...it is final so we can't reuse the class directly but have to make a copy. And this is where your alarm bells should go off. Admittedly we have been very generous in using final, maybe sometimes a bit too much, but the idea behind it is that we think that what you want to do can probably be done in a better way, or we simply don't know (and an unrelated reason is self protection so that we have more options for refactoring without breaking the whole world). So, any time you come across a situation where something is final and you think you have a really good use case to get rid of it, you should post a message here. Chances are we can tell you a better way to do it, or you convince us to remove final or in some other way facilitate your use case. As for your case, I'd like to hear what Al thinks about this. It might work to make the factor prepending into a separate, overridable method. Eelco - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: NoSuchMethodException / PropertyResolver
You have to provide the types for the fields, or else Wicket won't be
able to discover what type to use (apparently it resolves to boolean
for the name), or provide default values with the correct type in your
valuemap.
i.e. either:
add(new TextField(firstName, new PropertyModel(map, firstName),
String.class));
or
map.put(firstName, );

In other words, no modules may use the manifest to depend on classes from within a Web module. Is there another way other than using the manifest file? Editing the J2EE Module Dependencies only let's you add jar files, which supports the above statement. Why? - i have a legacy struts app and i would like to make a wicket war which uses the struts' app's backend which is burried in the struts war file. The other option could be to add a wicket servlet catching a different sub-url say /wicket/* - but not sure if that would work, and i'd like to keep the wicket app separate if possible.

Re: Inter component events?
Has anybody used something like javax.swing.ListModel.addListDataListener or java.util.Observable to setup a nice way for components to respond to changes in other components? My use case is that I have a basket of items a user has selected. While they are searching/browsing if an item already in the basket appears again I want it to be disabled/greyed out. With hand coding that is a bit ugly and seems like a candidate for some sort listening to changes in another component. This is where Wicket really works different from a desktop framework like Swing though. In swing you would generally push changes to observers. In Wicket, you have the request/ response cycle. 'Pulling' works better for Wicket, which typically means that you should make sure you update relevant state during requests (e.g. via models) so that other components use the updated state. So here, you wouldn't call setEnabled on the basket via some observer, but rather you would do something like override isEnabled and query the relevant state.

Hi all
Wicket version 1.2.4
I have this piece of code which is apparently causing wicket to send the

code
This code is present in a class called EditConfig. When I click on the link
basically
all it does is to refresh the page by creating a new instance of page.
new Link(refresh) {
@Override
public void onClick() {
setResponsePage(EditConfig.class);
}
}
/code
Apparently setResponsePage(EditConfig.class) causes the request target to be
a bookmarkable one
and the setting on respond method is to redirect the browser to the url
generated by the target-
which then again causes the event method to be processed - i.e in this case
page object to be created
again
Why would wicket want to keep redirecting . If after the page object has
been created , i thought it would render the page as is.
Am i missing something over here?
thanks

Re: [RFE] getMarkupId()
It's not a jquery bug at all. The '.' character is interpreted as a css class. So, the $(#quantity.noOfUnits1232) translates in element with ID quantity and css class noOfUnits1232.

The problem appear when I am trying to identify the component by it's id using some js library (like jQuery) and as a consequence the result of this query: $(#quantity.noOfUnits1232) is invalid. Thank you!

You need your own implementation of BodyContainer, and replace during

Hi all!!!
What I want to do is append some markup to my webpage after body tag.
I
can't override onRender method in HTMLBodyContainer because it is
created
by
method getBodyContainer() in WebPage.
I had to do the same thing, and was able to solve it.
To help you, I need to know what version of wicket you are using, and
what
markup you want to add, where it should come from.

Re: Experiences with ReloadingWicketFilter
* Peter Thomas: Just curious to know if others have problems with the ReloadingWicketFilter when you make minor changes to a page with markup inheritance, you may want to look at the issue history. FYI the problem described in the JIRA issue is not related to markup inheritance. The exception is thrown because the class TestPage is loaded from two different classloaders, thus TestPage(classloader1) != TestPage(classloader2). -- Jean-Baptiste Quenot aka John Banana Qwerty http://caraldi.com/jbq/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Passing Parameters to Bookmarkable Page
If the page is bookmarked, I don't care about retaining the filter. I just want the id for the item they want to view. But if they clicked the link from the list page (that has a list based on the filter), then when they return to the list page (save, cancel), I want to pass the filter back. The target page looks for the filter and simply passes it back. if there's nothing there, it passes nothing back. I would actually be nice to be able to explicitly set a URL together with the redirect to buffer strategy. For the buffer, it doesn't really matter what the URL looks like, and with this you'd be able to pass internal state to pages while still keeping your locations bookmarkable.

Re: Inter component events?
I see that it is not such an obvious win here as with fat client but how about another of my use cases: * Large page with small parts being updated by Ajax * Two components sitting long way apart in the tree (context sensitive button that responds to items in rest of the page) So having an almost declaritive style this button is enabled = fn(x) only works if I know when to re-render that button. I seem to be leaving OO behind by having lots of procedural when x happens update a, b and c rather than a subscribing to events from another component. Using some sort of event model seems to me to improve OO - encapsulation - reuse. For large trees of components with only tiny parts that need sending to the client it also seems more efficient. btw We are very pleased with our Wicket app as with JS it does nice partial updates and without JS it chugs along. We only alter the HTML for our modal window :) Eelco Hillenius wrote: Has anybody used something like javax.swing.ListModel.addListDataListener or java.util.Observable to setup a nice way for components to respond to changes in other components? My use case is that I have a basket of items a user has selected. While they are searching/browsing if an item already in the basket appears again I want it to be disabled/greyed out. With hand coding that is a bit ugly and seems like a candidate for some sort listening to changes in another component. This is where Wicket really works different from a desktop framework like Swing though. In swing you would generally push changes to observers. In Wicket, you have the request/ response cycle. 'Pulling' works better for Wicket, which typically means that you should make sure you update relevant state during requests (e.g. via models) so that other components use the updated state. So here, you wouldn't call setEnabled on the basket via some observer, but rather you would do something like override isEnabled and query the relevant state.

Questions about GWT, JSF and Wicket
Hello, at the moment I'm writing my diploma-thesis. The project I'm working on is for a big company in germany and consists of porting a Rich-Client-Java-Application to a web-based Application. It should make heavy use of AJAX-Components, because it should behave like the Rich-Client. If the experiences with the prototype turn out satisfactory, the complete application may be ported and maybe other applications will follow. At the moment I'm thinking about the architecture: From the Rich-Client I will reuse Spring, Hibernate and the Business-Objects, but I'm not sure which Web-Framework to choose from. I have used JSF in former projects and were not happy with it (the Web-Designer thought about committing suicide ;) Well for my thesis I have to give reasons, why I have chosen a specific technology and I have to convince some people, because they have hopes to raise some new projects out of the result of my project. They know about the JSF-Hype, but they don't know about Wicket. I have heared about it 2 weeks ago the first time. I'm doing a comparison between JSF and Wicket. I figured out a lot of disadvantages on JSF-Side, but I have no experience on Wicket-Side and it's disadvantages. I found out that JBoss Seam fixes some bad JSF issues. One guy in my department likes the Google Web Toolkit and is writing a book about it. I'll give it a try. It's a bit like Wicket from the programming style, but it needs a separate compiler and I haven't got a backend solution. I have red that it's possible to use GWT with Wicket. How far is this grown? I fear about a lack of AJAX-Wicket components, because I have seen only few components. I hope someone has experience with similar projects and can give me a few helpful advices. Thanks very much.

Re: Questions about GWT, JSF and Wicket
Hi, A list of url, that could help you... About Wicket vs JSF, there is some articles : * http://ptrthomas.wordpress.com/2007/05/14/a-wicket-user-tries-jsf/ (from the author of JTrac) * a list of articles : http://cwiki.apache.org/WICKET/articles-about-wicket.html About widgets : * take a look to * wicket-extensions : * wicketstuff (provide some way to integrate with third party js lib) : * a main difference with JSF and why I switch, it's the easier way to create custom component (see the documentation, wiki, slides). About GWT : Sorry I can't help you, :-(.

Re: Questions about GWT, JSF and Wicket
I wouldn't go for Wicket _and_ GWT. The server side could stay the same with GWT. The big change would be that GWT would make remote calls to it... If you need to support low end browsers then go for Wicket. If you don't go for GWT. Apart from no-javascript support the only other big problem is no Java 1.5 yet. Apart from those reservations it is a much better way to go. You will get a much more responsive application with GWT than you will ever get with Wicket.

For large trees of components with only tiny parts that need sending to the client it also seems more efficient we have a similar use case, where a tabbed panel displays items in different workflow states. To simplify: Tab 1: lists all new items Tab 2: lists all reviewed items Tab 3: lists all closed items For each list item, an ItemPanel is displayed, containing a button that will put the item in the next workflow state. We wanted to reuse this panel in all tabs. In order to be able to properly update models without hard coding page hierarchy into the ItemPanel, we defined an interface ItemStateChangeHandler, that provides the hook onItemStateChange(newState). All tabs implement this interface, and each ItemPanel is created with a reference to the ItemStateChangeHandler that is to be notified when it's about to change state. So when the 'nextState' button is clicked, the handler is notified and will be able to do stuff in the business layer (i.e. persist new state), adjust the list view's model and update the relevant components. Kind of home brew though, so we're very curious as to how others would implement a case like this. Kind regards, Wouter -- Wouter Huijnink Func.

most sensible factory pattern for a component
Seems like a common requirement to customise a component by having it create a different type of component within it. Like ListView.newItem or IItemFactory. Is extending the component to implement such a method any better than passing in an object that implements some factory interface? Passing in a factory object seems better for re-use since you can only extend an object once... Limits what the constructor can access more but that may be a good thing? Guess with an interface we get to choose. -- View this message in context: http://www.nabble.com/most-sensible-factory-pattern-for-a-component-tf4514777.html#a12877154 Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RequiredTextField(expectedNumberOfBoxes, Integer.class);
add(expectedNumberOfBoxesTextField);
RequiredTextField receivedNumberOfBoxesTextField = new
RequiredTextField(receivedNumberOfBoxes, Integer.class);
add(receivedNumberOfBoxesTextField);
}
Yep, you need to work with models. For instance:
RequiredTextField receivedNumberOfBoxesTextField = new
RequiredTextField(receivedNumberOfBoxes, Integer.class, new
PropertyModel(delivery, receivedNumberOfBoxes));
add(receivedNumberOfBoxesTextField);
or:
setModel(new CompoundPropertyModel(delivery));
RequiredTextField receivedNumberOfBoxesTextField = new
RequiredTextField(receivedNumberOfBoxes, Integer.class);
add(receivedNumberOfBoxesTextField);

Re: Redirect to HTTPS?
Eelco Hillenius wrote: I stand by my suggestion that you could just try to redirect to a secure page. After that, the relative URLs stay secure no? If I'm missing something, please tell. Eelco I think we are both missing something. There are a couple of situations (aka requirements) that I want to describe and hopefully get your opinion on how to go about solving them. 1. A page has information that needs to be secure, i.e. demographic information, billing information. This information can be accessed from a non-secured page, i.e. home page I believe what you proposed can be accomplished. Not sure how though. A working example would do wonders here. I am still learning Wicket. 2. Submitting a form has to be secure, i.e. login information, demographics information This can be from a non-secure page (login home page) or secure-page (demogaphics page). Not sure how to do this without the proposed refactor (doPostPrepend()) since the URL generation is encapsulated and final. 3. When on a secure page, link to a non-secure page (from demographics page to company info) Wicket currently builds URLs that are relative to domain and agnostic to protocol (https/http), i.e. /?wicket=... What this does will do if redirect to a secure page is keep all subsequent links in the https mode. Therefore, this will place an undo amount of load on the https server and potentially slow down the user experience. The proposed refactor would mitigate 1 and 3. For 2, I foresee a SecureLink/SecureButton/SubmitLink (and others?) that would need to created which has the RequireSSL annotation. By doing so, it would fit nicely in the proposed refactor. Does this clear it up? These are actual client requirements and not sure how to proceed without the proposed solution.

I have no problem with the approach in finals. I think you guys have done a great job. Please see my response http://www.nabble.com/Redirect-to-HTTPS--tf4509537.html#a12878724 here I, too, am very interested in the feedback on this. Eelco Hillenius wrote: I haven't tested but I think the solution is to override public final CharSequence encode(final RequestCycle requestCycle,final IRequestTarget requestTarget)BUT...it is final so we can't reuse the class directly but have to make a copy. And this is where your alarm bells should go off. Admittedly we have been very generous in using final, maybe sometimes a bit too much, but the idea behind it is that we think that what you want to do can probably be done in a better way, or we simply don't know (and an unrelated reason is self protection so that we have more options for refactoring without breaking the whole world). So, any time you come across a situation where something is final and you think you have a really good use case to get rid of it, you should post a message here. Chances are we can tell you a better way to do it, or you convince us to remove final or in some other way facilitate your use case. As for your case, I'd like to hear what Al thinks about this.

Re: Inter component events?
Maybe something like: http://www.javaworld.com/javaworld/jw-11-2001/jw-1109-subscriber.html?page=4 No big extra jars... Would be nice if buttons could just subscribe to some standard set of messages (e.g. change of focus) Wouter Huijnink wrote: I see that it is not such an obvious win here as with fat client but how about another of my use cases: * Large page with small parts being updated by Ajax * Two components sitting long way apart in the tree (context sensitive button that responds to items in rest of the page) So having an almost declaritive style this button is enabled = fn(x) only works if I know when to re-render that button. I seem to be leaving OO behind by having lots of procedural when x happens update a, b and c rather than a subscribing to events from another component. Using some sort of event model seems to me to improve OO - encapsulation - reuse. For large trees of components with only tiny parts that need sending to the client it also seems more efficient we have a similar use case, where a tabbed panel displays items in different workflow states. To simplify: Tab 1: lists all new items Tab 2: lists all reviewed items Tab 3: lists all closed items For each list item, an ItemPanel is displayed, containing a button that will put the item in the next workflow state. We wanted to reuse this panel in all tabs. In order to be able to properly update models without hard coding page hierarchy into the ItemPanel, we defined an interface ItemStateChangeHandler, that provides the hook onItemStateChange(newState). All tabs implement this interface, and each ItemPanel is created with a reference to the ItemStateChangeHandler that is to be notified when it's about to change state. So when the 'nextState' button is clicked, the handler is notified and will be able to do stuff in the business layer (i.e. persist new state), adjust the list view's model and update the relevant components. Kind of home brew though, so we're very curious as to how others would implement a case like this. Kind regards, Wouter -- Wouter Huijnink Func.

Regards, Ate Douma Ate Douma wrote: I'm really happy to announce that a new and quite feature complete Wicket Portlets Demo is now available for download at: http://people.apache.org/~ate/wicket/jetspeed-2.1.3-dev-wicket-demo-installer.jar I've worked hard the last few weeks to improve the Wicket portlet support branch and it can now run all Wicket Examples natively as portlet! See also IRA issue WICKET-658 at http://issues.apache.org/jira/browse/WICKET-658#action_12528082 where I have provided more information how to install and use this demo. Although there probably are still some minor issues here and there, the demo will show that portlet development using Wicket is now very much feasible. I'd like to invite anyone interested to try out the demo and see it in action for yourself, and of course please report any encountered issue/problems to the dev list. I've developed the portlet support based on the 1.3.0-beta3 release (with few minor bugfixes ported back from the trunk), so although the trunk development has progressed at it usual aggressive speed, updating the portlet-support to the latest Wicket trunk shouldn't be too much work (that is: right now!). As we would like to start using Wicket for a rewrite of the Jetspeed-2 administration portlets *now*, it would be great if the portlet support can be incorporated into the trunk as soon as possible. Delaying this until after the 1.3.0 release would mean being out-of-sync with the main wicket trunk development all the time and a lot of work each time we want/need to bring it back in sync. Initially, back in May this year, my idea was waiting with merging the portlet support in the trunk to after the 1.3.0 release. But as 1.3.0 still isn't released yet and still in beta phase, it would be much better to merge now otherwise the portlet-support will be constantly out-of-sync with the main wicket trunk development, causing a lot of effort each time we want (or need) to bring it back in sync. For Jetspeed-2, we would very much like to start using Wicket for a rewrite of the Jetspeed-2 administration portlet *now*. Having towait until after the 1.3.0 release, or be dependent on unofficial builds from the portlet-support branch would be less ideal to say the least. Other parties, like my own company, already have started using the Wicket portlet-support branch, so having to delay the merge to trunk really wouldn't be fun. AFAICS though, the impact of merging the portlet-support to trunk won't be big. I had to make a few (internal) changes in the wicket core, but I don't think those will have functional side-effects. To make it easier for the other committers to decide if we can merge the portlet-support to trunk now, I will create a new JIRA issue for it. For the changes needed to the current Wicket trunk I'll create separate patches with explanations why and attach those to that issue. (note: most of these changes I already described in detail under subtasks of the WICKET-647 issue). We can then discuss these changes individually and if need be see if alternative solutions are possible. After those changes are reviewed and accepted, the portlet support then can be merged to the trunk. WDYT?

Re: [OT] Making it easy for Designers in my Wicket project
The way I tackled this was to put all my html pages in src/main/resources instead of src/main/java to keep them separate from the .java files (so as not to confuse the designers). So for instance, I might have: src/main/resources/com/mycompany/wicket/home/HomePage.html src/main/resources/com/mycompany/wicket/user/AddPage.html src/main/resources/com/mycompany/wicket/user/UserPanel.html src/main/webapp/css src/main/webapp/img Then what I did was I installed Tortoise SVN and Apache Web Server (not Tomcat) on the designers machine. Also on their machine, I created a wwwroot/myproject directory and under there I linked: wwwroot - myproject - home - svn://...src/main/resources//home - user - svn://...src/main/resources//user - css - svn://...src/main/webapp/css - img - svn://...src/main/webapp/img Then I configured apache for that directory, and that's the test website Dreamweaver launches after they make edits and want to preview. When the designer is all done, they do an SVN Commit through Tortoise. Hope that helps, Craig. On 9/25/07, Sjoerd Lohuis [EMAIL PROTECTED] wrote: This is something I'm looking for as well.

how to add dynamically typed form components?
Hi list,
I've seen some threads on dynamically adding components to a form, but
those mainly concern a dynamic *number* of components of the same type.
Our use case concerns adding dynamically typed components to a form. The
idea is as follows:
We have XML consisting of XHTML elements and optional nested xml
elements from another namespace - something like:
div
psome silly info here/p
somenamespace:interaction type=a [custom stuff for this
namespace]/somenamespace:interaction
peven more info here, and a nested element:
somenamespace:interaction type=b [custom stuff for this
namespace]/somenamespace:interaction
/p
/div
What we want to achieve, is to create a (Form?)Component subclass that
can add a FormComponent to itself (or to the form?) for each
interaction, where the actual component created depends on the 'type '
attribute of the interaction.
So the xml snippet should in the end be displayed in the user's browser as:
div
psome silly info here/p
input type=text id=generatedId1 class=type-a/
peven more info here, and a nested element:
textarea id=generatedId2 class=type-b/textarea
/p
/div
Our thoughts on this:
1. Transform the XML to wicket markup. Temporary result:
div
psome silly info here/p
input type=text wicket:id=generatedId1 class=type-a/
peven more info here, and a nested element:
textarea wicket:id=generatedId2 class=type-b/textarea
/p
/div
2. Feed this markup to a Panel subclass that overriding
getMarkupResourceStream()
The panel overrides getMarkupResourceStream thus:
public IResourceStream getMarkupResourceStream(MarkupContainer
container,
Class containerClass) {
String markup = String.format(wicket:panel%s/wicket:panel,
getModelObject());
return new StringResourceStream(markup);
}
In the constructor of this panel the provided wicket markup is set as
its model, and the associated markup stream is iterated to dynamically
add form components backing the generated input tags:
public MarkupProvidingPanel(String id, IModel model) {
// model contains a modelObject of type String containing wicket markup
super(id, model);
final MarkupStream associatedMarkupStream =
getAssociatedMarkupStream(false);
while(associatedMarkupStream.hasMore()) {
MarkupElement element = associatedMarkupStream.next();
if (element instanceof ComponentTag) {
ComponentTag componentTag = (ComponentTag) element;
if (input.equals(componentTag.getName())) {
String type =
componentTag.getAttributes().getString(type, text);
if (text.equals(type)) {
add(new TextField(componentTag.getId()));
} else if (submit.equals(type)) {
add(new Button(componentTag.getId(), new
Model(do it!)));
}
}
}
}
}
Any thoughts on the viability of this approach? Any alternative approaches?

Wouter

Re: Calling all translators - UrlValidator translation

The English in question is:

As an Free software project, I'm a bit surprised Wicket doesn't use the

does it?)
There's a bunch of specialized tools available for the gettext .po
format that free software translators have on their belt. Surely that
would work more producively than asking for translations on a mailing

Using the XLIFF format together with Sun's translation editor or OmegaT
would be another viable option.

Re: Questions about GWT, JSF and Wicket
Is the browser not a client in Wicket? You have to slice things differently. I agree that using GWT will mean more thought has to go into interaction with the middle tier but that just means some of your code stays on the server in some simple facade. It wouldn't be one of my worries in using GWT. In Wicket or GWT when the user clicks something you have to marshall the same data for both. If Wicket uses a remote middle tier (including DB) very similar issues will crop up. We have found the need to make some of our model serializable to make working with Wicket nice. Obviously lots of pros and cons for both that have not been mentioned so far. igor.vaynberg wrote: how about another tiny limitation which is the programming model. gwt is essentially client+server so you cannot use hibernate lazy loading, you cannot use data locality to your advantage either. you have to serialize all your data so you can only use simple objects to communicate between your server and ui. but those are not at all important are they? -igor On 9/25/07, Sam Hough [EMAIL PROTECTED] wrote: Another big GWT limitation is that you have a very small subset of java runtime to write your UI in.

How do I achieve this?
It is quite straightforward for images, but it gets trickier with
background-images to other html elements..
If you object to style attributes on your HTML tags, then you can do
this by writing stuff out to the head of your page.
private static final ResourceReference IMAGE = /* ... */;
...
final Component component = /* ... */;
page.add(new AbstractBehavior() {
public void renderHead(IHeaderResponse response) {
String url = urlFor(IMAGE);
String foo = style\n;
foo += # + component.getMarkupId() + {\n;
foo += background-image: url( + url )\n;;
foo += }\n;
foo += /style;
response.renderString(foo);
}
});
Should work. ;-)

RE: Form Feedback
Hey Gerolf,
I used the following to do feedback as you suggested, but the red * is
always visible, rather than just after an error, even on rendering the
page before I do any submits.
Here is the code I have in my Form's constructor:
RequiredTextField itemid = new
RequiredTextField(itemid,Integer.class);
FormComponentFeedbackIndicator fd = new
FormComponentFeedbackIndicator(itemidFeedback);
fd.setIndicatorFor(itemid);
add(itemid);
add(fd);
And Here is the Code I have in the html file (inside the form):
tr
tdItemId:span wicket:id=itemidFeedback//td
tdinput type=text wicket:id=itemid//td
/tr
On further investigation, I sublassed FormComponentFeedbackIndicator and
overwrote the isVisible() method like this:
public boolean isVisible()
{
return
Session.get().getFeedbackMessages().hasMessage(getFeedbackMessageFilter(
));
}
With this change, the * shows up only when I would expect it to...
Do you have any idea what would cause the default behavior not to work
properly?
This is all setup in a QuickStart project, using Java 1.4
Thanks for any help.

Re: BookmarkablePageLink doesn't take advantage of pretty url for previously mounted pages when generating the URL
Done: https://issues.apache.org/jira/browse/WICKET-1008 I will try and look at the code to see if I can identify the cause.

Updating a Dynamic Image with AJAX (and JFreeChart)
I am integrating JFreeChart into my application and I've followed the
JFreeChart example on the wiki. That works very nicely. I was impressed.
What I want to do now is update the graph that I display based on the
selection from a drop down list. I've successfully added the DropDownChoice
component and added a AjaxFormComponentUpdatingBehavior to it. I've
verified that my onUpdate( AjaxRequestTarget ) method is being invoked and
I'm receiving the updated value, which is very cool. Here is my onUpdate
implementation for the DropDownChoice control:
protected void onUpdate( AjaxRequestTarget target ) {
log.debug( graphStyles onUpdate invoked! SelectedGraphStyle = +
FieldResultsPanel.this.getSelectedGraphStyle() );
FieldResultsPanel.this.updateGraph(); // Update the model and re-create
the JFreeChart Image
// fieldGraph is my JFreeChartImage instance (derived from Image)
// This is supposed to indicate back to the browser that the image needs
updated. I think this
// is working properly
target.addComponent( FieldResultsPanel.this.fieldGraph );
}
Even though I am updating the model of my JFreeChartImage, it appears that
the getImageData method is never invoked afterwards.
What do I need to do in order to get the image data to be re-read?
Here is my JFreeChartImage class:
public class JFreeChartImage extends Image {
private static final Logger log = LoggerFactory.getLogger(
JFreeChartImage.class );
private int width;
private int height;
public JFreeChartImage( String id ) {
super( id );
}
public JFreeChartImage( String id, int width, int height ) {
this( id );
this.width = width;
this.height = height;
}
public JFreeChartImage( String id, JFreeChart chart, int width, int height
) {
super(id, new Model( chart ) );
this.width = width;
this.height = height;
}
public Component setModel( JFreeChart chart ) {
log.debug( setModel invoked with chart: + chart );
return super.setModel( new Model( chart ) );
}
@Override
protected Resource getImageResource() {
return new DynamicImageResource(){
private static final long serialVersionUID = 1L;
@Override
protected byte[] getImageData() {
log.debug( Invoking getImageData... );
JFreeChart chart = (JFreeChart)getModelObject();
log.debug( Chart object: + chart );
return toImageData( chart.createBufferedImage( width, height ) );
}
@Override
protected void setHeaders( WebResponse response ) {
if ( isCacheable() ) {
super.setHeaders(response);
} else {
response.setHeader( Pragma, no-cache );
response.setHeader( Cache-Control, no-cache );
response.setDateHeader( Expires, 0 );
}
}
};
}
Any help is much appreciated!

Re: Form Feedback
you probably have to call FormComponentFeedbackIndicator#updateFeedback in
onSubmit and onError,
but i think overriding isVisibile is the the better approach.
maybe FCFI should override isVisible itself...

Hey Gerolf,
I used the following to do feedback as you suggested, but the red * is
always visible, rather than just after an error, even on rendering the
page before I do any submits.
Here is the code I have in my Form's constructor:
RequiredTextField itemid = new
RequiredTextField(itemid,Integer.class);
FormComponentFeedbackIndicator fd = new
FormComponentFeedbackIndicator(itemidFeedback);
fd.setIndicatorFor(itemid);
add(itemid);
add(fd);
And Here is the Code I have in the html file (inside the form):
tr
tdItemId:span wicket:id=itemidFeedback//td
tdinput type=text wicket:id=itemid//td
/tr
On further investigation, I sublassed FormComponentFeedbackIndicator and
overwrote the isVisible() method like this:
public boolean isVisible()
{
return
Session.get().getFeedbackMessages().hasMessage(getFeedbackMessageFilter(
));
}
With this change, the * shows up only when I would expect it to...
Do you have any idea what would cause the default behavior not to work
properly?
This is all setup in a QuickStart project, using Java 1.4

Using some sort of event model seems to me to improve OO - encapsulation - reuse. For large trees of components with only tiny parts that need sending to the client it also seems more efficient. Yeah, if most of what you're doing is Ajax, you need to find a way to know which components should be updated and my remarks are less relevant. Still, I think most of it should be communicated via models. It shouldn't be hard to let your model(object)s implement an observer pattern and use that to your advantage.

well, the problem is you are trying to bind two things to the same event. the order of execution is not always clear if i call add(A) followed by add(B) does it always execute A,B or can B,A be acceptable? if it is A,B does B still execute if A fails? do we need to somehow prevent A from doing a return false; and preventing B from executing? etc etc etc. there is just no easy way to do this automatically and get all the usecases right. -igor On 9/25/07, UPBrandon [EMAIL PROTECTED] wrote: I did that and it worked.

I'm justhoping that something canbe done (or un-done) to improve the developer experience when using ReloadingWicketFilter. To be honest ReloadingWicketFilter is a hack to work around how the JVM loads classes, and it is bootstrapped during the Wicket application initialization. If ReloadingWicketFilter is causing more problems than it is meant to solve, we might simply want to remove it from Wicket, especially if it proves to be unreliable in complex setups. Unless you're willing to turn your hope into contribution? That's a little harsh. Have a look in the JIRA and I've repeatedly said how much I appreciate the RWF and even the way it works now (even citing it as the reason for not moving to groovy!). Thanks for the gentle reminder that I should quit whining about this. I'm not a master of classloading and it is unlikely I contribute anything in this area. Have you seen my suggestion to clear your session cookie before reloading the page BTW? All this is very complicated I realize, but there's not much we can do to simplify reloading. -- I saw your suggestion on clearing cookies, thanks. I'll say this one last time and then shut up - I completely understand that this is a hack and all - but it used to work the way I expected and at least one other user felt the same. I was just pushing my luck (at the risk of losing mailing-list karma) because as the other user said, once you have experienced page refresh reload of classes it is very hard to go back. But you are saying nothing more can be done, and I respect the opinion of the Wicket committers on this and I can live with how it is now. I completely appreciate the work that you and other Wicket committers have put into RWF and it is a huge time saver in its current form. Thanks, Peter.

Re: Calling all translators - UrlValidator translation
LGPL is also problematic for Apache projects. And we can't use the texts coming out of such tools since they are (L)GPL too.

Hi Martijn, Op woensdag 26-09-2007 om 00:57 uur [tijdzone +0200], schreef Martijn Dashorst: LGPL is also problematic for Apache projects. Are you sure? I don't think this holds any more: http://gettext-commons.googlecode.com/svn/trunk/README states This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) _any_later_version_. (emphasis mine) As you may know the Free Software Foundation has worked with Apache to make version 3 of its licenses compatible with the Apache license. Version 3 is available since a few months now. The article on http://blogs.zdnet.com/Burnette/?p=153 backs up what I'm saying: In other words, LGPL code can be combined with code using any other license, whether free, open, or proprietary. Unlike LGPLv2, this version makes it very clear that linking or combining in any way is allowed. And we can't use the texts coming out of such tools since they are (L)GPL too. Are you saying that user-created external data (translations) becomes licensed under the same license as the (L)GPL program used to process it? Sorry but I find that hard to believe-- I might have missed something, but as far as I know, it works this way: the original author of the translation retains copyright but licenses his work for distribution under the same conditions as the accompanying program. Much like regular code, actually. regards, -- Reinout van Schouwen - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: NoSuchMethodException / PropertyResolver

You have to provide the types for the fields, or else Wicket won't be
able to discover what type to use (apparently it resolves to boolean
for the name), or provide default values with the correct type in your
valuemap.
i.e. either:
add(new TextField(firstName, new PropertyModel(map, firstName),
String.class));
or
map.put(firstName, );
No joy, I tried both suggestions (see code below) and still get the
both a NoSuchMethodException and a NoSuchFieldException for each field
(see stack trace below).
Of course this doesn't actually stop anything from working, as far
as I can tell, so it's not a big deal to me. But it seems like
something still isn't quite right.

FeedbackPanel issue [EMAIL PROTECTED]
After I do all my valid info into my form I get something that reads:
[EMAIL PROTECTED]
I'm not sure where it's coming from. I've commented out everything in my
form except for one text input- and it still returns the above.
Can anyone help with this?
Here's AmountsTimesDatesStore.java
package foo;
import java.io.Serializable;
public class AmountsTimesDatesStore implements Serializable {
private String ZoningUse;
public String getZoningUse(){
return ZoningUse;
}
public void setZoningUse(String ZoningUse){
this.ZoningUse = ZoningUse;
}
private static final long serialVersionUID = 1L;
}
What I don't understand is why it's returning anything at all. All my
fields are filled in and validated. Why onSubmit does it do this?
Here is some of my html/java file that may have something to do with this?
class AmountsTimesDatesForm extends Form{
public AmountsTimesDatesForm(String id, IModel model){
super(id,model);
}
@Override
public void onSubmit() {
info(getModelObjectAsString());
}
}
Border addWithBorders(Form form,FormComponent component,String
borderId){
AjaxResponsiveFormComponentFeedbackBorder border = new
AjaxResponsiveFormComponentFeedbackBorder(borderId);
border.setOutputMarkupId(true);
border.add(component);
form.add(border);
return border;
}
void addAjaxBehaviorToComponent(FormComponent formComponent, final
Border border, final FeedbackPanel feedback){
formComponent.add(new AjaxFormComponentUpdatingBehavior(onblur) {
@Override
protected void onUpdate(AjaxRequestTarget target){
target.addComponent(feedback);
target.addComponent(border);
setResponsePage(Location.class);
}
});
}
Any help would be appreciated.
Thanks

Re: [OT] Making it easy for Designers in my Wicket project
I'm interested in this problem, too... question below. Then what I did was I installed Tortoise SVN and Apache Web Server (not Tomcat) on the designers machine. Also on their machine, I created a wwwroot/myproject directory and under there I linked: wwwroot - myproject - home - svn://...src/main/resources//home - user - svn://...src/main/resources//user - css - svn://...src/main/webapp/css - img - svn://...src/main/webapp/img Then I configured apache for that directory, and that's the test website Dreamweaver launches after they make edits and want to preview. When the designer is all done, they do an SVN Commit through Tortoise. I don't quite understand this second part. What do you mean by you linked wwroot/blah/blah to svn://blah/blah? You mean you just checked out svn into that dir? Why do you need to install Apache on the client machine if you're just using static files? Can't your designer just access with the file:// url? Finally, the most important thing for the designer is to view the stuff in context. It doesn't mean much for the designer to see this html: wicket:panel div wicket:id=someReallyComplicatedComponent/ /wicket:panel Are you saying you don't set up anything so your designers can view someReallyComplicatedComponent in context with the application?

Page Expired Clustering?
I am having trouble with a wicket application returning page expired when any link or button is clicked on. When the application is deployed on a server with an Apache Weblogic integration the application works fine. When the application is deployed on a server with an Apache Weblogic cluster all links and buttons return page expired. I am using Wicket 1.2.6 and JDK 1.4. The wicket application is also integrated with hibernate and Spring.
