Re: Ajax validation error messages
Why not just put a filter on your 'global' feedbackpanel and filter out
the messages that you already display for each component? E.g. I have
the following code in a form:
private void addGlobalSubmitPanel() {
final List components = getFormComponents();
final FeedbackPanel feedback = new FeedbackPanel(FEEDBACK);
feedback.setFilter(new IFeedbackMessageFilter() {
public boolean accept(FeedbackMessage message) {
return !components.contains(message.getReporter());
}
});
add(feedback);
}
private List getFormComponents() {
final List components = new
ArrayList();
visitFormComponents(new FormComponent.IVisitor() {
public Object formComponent(IFormVisitorParticipant
formComponent) {
final FormComponent fc = (FormComponent)formComponent;
components.add(fc);
return Component.IVisitor.CONTINUE_TRAVERSAL;
}
});
return components;

Re: Page models

Nested forms and IndicatingAjaxSubmitButton - multiple issues
Hi, I have IndicatingAjaxButton in a form within a panel, panel itself is inside another wrapper form on the enclosing page. Seems like I get really weird behavior based on how many forms I have on the page - even though the ajaxsubmit button's form hierarchy doesnt really change. Condition 1: When there are 2 forms - indicatingajaxbutton -> form -> panel -> form -> page In both IE and FF onSubmit() of the indicatingajaxbutton gets called correctly - but entire page gets reloaded instead of just updating the targets added to the ajaxtarget. Even though the containing page in the above hierarchy is bookmarkable page In IE the url changes to wicket:interface::10:2 etc. Condition 2: When there are atleast 3 forms - indicatingajaxbutton -> form -> panel -> form1, form2 (at the same level) -> page In FF most of the time it works correctly - although every now and then I do see the loadabledetachable model load method not even called for the updating components In IE 7 - Dont get a call to onSubmit() for indicatingajaxbutton at all but the page reloads and again even though the page is bookmarkable - wicket:interface url shows with the bumped version number Can someone think of any work arounds while this gets looked at? -- View this message in context: http://www.nabble.com/Nested-forms-and-IndicatingAjaxSubmitButton---multiple-issues-tp19190442p19190442.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Generics - Re: First impressions of 1.4-m3
I'm probably too late coming into the discussion but from reviewing past
threads it appears the only reason for 1.4-m3 over m2 and removing
generics from Component is because some things like Page and Label don't
make sense with generics?
If that is really the only reason (and there may be others that I just
didn't understand) why can't we make Component generic and then do:
public class Label extends WebComponent {
...
}
and now Label is not generic anymore.

Edward wrote:
I've been a little busy so just took my first look at 1.4-m3 and spend a
few minutes upgrading a small app. So far the only thing I wish were
different is for getModel and getModelObject to not have been changed to
getDefaultModel and getDefaultModelObject. That breaks old code and
some things like libraries I may not have control over to upgrade. My
preference would have been to keep them the same and have the new
generic ones named something else like getComponentModel and
getComponentModelObject. This way old code still works but I have a
migration path to start using generics in my app.
Just my $.02

Ajax validation error messages
Hi. Can anyone recommend a good strategy for handling and dislplaying validation error messages when using Ajax? I want my basic field validation error to show next to the relevant input text boxes, and have used my own FormComponentFeedbackBorder to do this. I still want a feedback panel for more fatal backend errors - eg, "record already exists", "concurrent record modification", etc. Problem. If I put a feedback panel on the page, and repaint this in my button's onError with target.addComponent(feedback) - then I get duplicates of my field validation errors in my panel. Not what I want. If I only repaint the feedback onSubmit then I can catch the backend error and display my message. But subsequent Ajax form submissions don't refresh the page, so the error message in the feedback panel "sticks" on the page. Not sure how to clear out existing errors in the feedback panel when using Ajax, so have now used a label on my page instead, and manually clean up after myself. But is this the best way to go? -- View this message in context: http://www.nabble.com/Ajax-validation-error-messages-tp19190006p19190006.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: fileupload element checking filename existing before upload using ajax
Found a different solution, in case somebody is interested:
fileUploadField.add(new AjaxEventBehavior("onchange")
{
protected void onEvent(AjaxRequestTarget target) {
Request request = RequestCycle.get().getRequest();
String filename = request.getParameter("filename");
System.out.println("filename is [" + filename + "]");
}
public CharSequence getCallbackUrl(boolean
onlyTargetActivePage) {
CharSequence callBackUrl =
super.getCallbackUrl(onlyTargetActivePage);
return callBackUrl + "&filename=' + this.value + '";
}
});
not as beautiful as I'd like to have it, because I'm manually messing around
with the callback url, but it works :-).

Re: fileupload element checking filename existing before upload using ajax
That's what I've found, too, that uploading using ajax is not possible. But :-), I don't need the upload to be ajax, all I need is the filename, as soon as the file was choosen by the user. That way I could validate the filename serverside, and provide immediate feedback, before the (maybe) long upload is performed. So, just adding a parameter to the ajax "onchange" call would do the trick. What I'll try now is adding another "hidden" ajax form, link the file upload element to a hidden field in this form, and then "manually" submit this form, by adding my own "wicket free" javascript... not beautiful, but should work.

Re: Maven QuickStart in Eclipse on Tomcat
If I knew enough about Jetty to be confident that there would be no hitches there, that would certainly be the optimal solution (and, given your experience with it, I'm sure you're right.) But considering that my knowledge of Jetty is perhaps on par with my knowledge of the history of Abkhazia, I figure that it's safer for now to run everything in the same server environment. igor.vaynberg wrote: > > same, no one said anything about switching anything in production env. > > -igor > -- View this message in context: http://www.nabble.com/Maven-QuickStart-in-Eclipse-on-Tomcat-tp19183955p19188753.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: GetModelObject returns null-filled Object?
I´m using it that way:

(Users) this.getModelObject();
String bar =
foo.getNick();
if
(!validateForm(foo)) {

}
@Override

}
};
regF.setOutputMarkupId(true);
u.setPasswort(pw);

BoundCompoundPropertyModel(u);
regF.setModel(model);
FormComponent nick = new TextField("nick")

Any Idea?

Re: application scope objects in Wicket
Thank you both for your answers, Jeremy and James.
The data structure I'll use in the real case will be a collection of
objects with
one object for each of the user sessions.
That same object will be accessed only once outside the user session
and then it will be erased. There won't be 2 threads accessing the same
object in the collection
at the same time but they will access the collection object itself
concurrently (even if on separate elements).
That's why I thought about using synchronized methods only for removing,
setting and adding an element in the Collection,
I hope this will work correctly without affecting the performance of the
WebApplication object.
Don't know if I should incapsulate the collection in another object
member of WebApplication and implement the synchronized methods
inside it.
I didn't post these details because my doubt was really on the
correctness of overriding the get() method of WebApplication
to enable the use of application scope objects.
Thanks for the advice and cheers,
Marvan
James Perry wrote:
Firstly I hope you are enjoying building your first Wicket web app.
Is this application scope object immutable? What is the data structure?
IMHO, if it's immutable then it's OK to use composition within your
WebApplication by adding this object as a field within WebApplication.
I would just make it final so it never gets incorrectly pointed to a
different object once initialized.
However if this has mutable shared data, then do not use the
WebApplication's intrinsic lock as you will jeopardize its throughput
to process requests. For example:
public class FooBarApplication extends WebApplication {
private MyAppScopeObject appScopeObject;
public synchronized MyAppScopeObject getAppScopeObject(){
return appScopeObject;
}
public synchronized void setAppScopeObject(MyAppScopeObject appScopeObject) {
this.appScopeObject = appScopeObject;
}
}
Instead, use your application-scope object's intrinsic lock or use a
suitable mutex in the Java 5/6 API.
Best,
James.

Hi all, I'm new to Wicket and developing my first Wicket website.
I have some temporary objects created inside a users' session but needed by
a parallel process which uses them

them into a database.
I'm looking at using application scope objects but I'm not sure how to do it
best
in Wicket.
I guess I should override the get() method of WebApplication
mimicking the pattern used for custom Session objects.
public class WicketApplication extends MyWebApplication
{
private Object applicationScopeObject;
public WicketApplication() {
setApplicationScopeObject( );
}
@Override
public static WicketApplication get() {
return (WicketApplication) WebApplication.get();
}
public Object getApplicationScopeObject(){
return this.applicationScopeObject;
}
public void setApplicationScopeObject( Object applicationScopeObject ){
this.applicationScopeObject = applicationScopeObject;
}
[...]
}
public class PageInsideUserSession
{
public PageInsideUserSession(){
[...]
// object has already been initialized
WicketApplication.get().setApplicationScopeObject( object );
}
}
public class PageOutsideUserSession
{
public PageOutsideUserSession(){
Object object = WicketApplication.get().getApplicationScopeObject();
[...]
}
}
In my case synchronizing the access to the application scope object should
not be needed.
Is this approach correct (and efficient) or is there a better solution ?
Should I maybe use a separate parent class (parent of WicketApplication and
child of WebApplication) for
overriding the get() method (in case the override interferes with something
else in the framework) ?

Marvan

Wicket Cart: open-source e-commerce wicket app
Is anyone interested in contributing to an open-source e-commerce wicket engine? I was thinking of calling it WicketCart. I have written a primitive version which serves as a good foundation to build upon. I have a new client, a royal college, requiring an e-commerce web app so just pondering the idea of WicketCart. If other developers are interested in contributing then I will make it open-source. I have written it so far using Spring and Hibernate but very open for it to additionally be implemented for other frameworks. If anyone wants specific details or wants to discuss it a bit more, then feel free to email me.

First impressions of 1.4-m3
I've been a little busy so just took my first look at 1.4-m3 and spend a few minutes upgrading a small app. So far the only thing I wish were different is for getModel and getModelObject to not have been changed to getDefaultModel and getDefaultModelObject. That breaks old code and some things like libraries I may not have control over to upgrade. My preference would have been to keep them the same and have the new generic ones named something else like getComponentModel and getComponentModelObject. This way old code still works but I have a migration path to start using generics in my app. Just my $.02 Edward - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

the problem is file uploading with ajax - that's just not possible (restriction of the http protocol as far as I remember), however you can 'simulate' using some approaches, e.g. a hidden iframe where you post your file to. that topic has been discussed many times, just search the list - if i remember correctly there's already a component for that somewhere in wicketstuff ... regards, Michael Thomas Lutz wrote: > > Hi list ! > > I'm trying to build a upload form consisting of one ore more fileuploads. > > If the file(s) already exist(s) on the server, I'd like to throw a > validation message, but, before uploading takes place. > > I tried to attach AjaxEventBehavior to the FileUploadField, onchange is > executed, but I've no access to the current value of the file input > element.

Maven QuickStart in Eclipse on Tomcat
I'm trying to run the Wicket QuickStart app in Eclipse on Tomcat. I'm entirely new to Maven and its dependencies (which seem to be just project libraries?) I think I have it mostly configured correctly, but when I start Tomcat I get the following error: java.lang.ClassCastException: org.apache.wicket.protocol.http.WicketFilter cannot be cast to javax.servlet.Filter at org.apache.catalina.core.ApplicationFilterConfig.getFilter(ApplicationFilterConfig.java:255) at org.apache.catalina.core.ApplicationFilterConfig.setFilterDef(ApplicationFilterConfig.java:397) . . . Obviously, it's not finding the wicket-1.3.4.jar. Here are my screenshots from Eclipse: http://www.nabble.com/file/p19183955/packageExplorer.png and http://www.nabble.com/file/p19183955/buildPath.png So it appears that the wicket jar is there under Maven Dependencies. Is there anything I need to do in order to get the items under Maven Dependencies to be recognized by the application?

fileupload element checking filename existing before upload using ajax
Hi list ! I'm trying to build a upload form consisting of one ore more fileuploads. If the file(s) already exist(s) on the server, I'd like to throw a validation message, but, before uploading takes place. I tried to attach AjaxEventBehavior to the FileUploadField, onchange is executed, but I've no access to the current value of the file input element. Tried AjaxFormComponentUpdatingBehavior as well, no success. How should I approach this ? Basically all I need is ajaxing the onchange with the "new value" back to the server.

Re: GetModelObject returns null-filled Object?
What model are you using for the form? How are you setting it?
While you're there have a look at IFormValidator (look at its
implementations to see how to use it) as it's much neater to add your
Hibernate validator like this rather then hard coding it in your
overridden onSubmit method.
Best,
James.

String bar = foo.getNick();
//Hibernate-Validator validateForm()
if (!validateForm(foo)) {

but bar contains the right value?
Why is this the way it is? Can I change it?
Because Hibernate Validator also can´t read out the correct content and says
it is null or empty :(

It seems that this happens only in 1.4. Maybe because I haven't added CompoundPropertyModel. Does anybody know what is it for? * A simple compound model which uses the component's name as the property expression to retrieve * properties on the nested model object. * * CompoundPropertyModel is a chaining model so it will call get/setobject on the given object if * the object is an instanceof IModel itself.

Question regarding [WICKET-1420] - Allow to change charset in St ringRequestTarget
Hi,
we ran into trouble with the StringRequestTarget on Wicket 1.4-m3, when our
system file.encoding was different from the encoding used for the
communication between Wicket and the web browser. In short, we use UTF-8 for
our web pages and JSON. Java uses Cp1252 as file encoding on one of our
machines, so the CharSet of the OutputStream used by StringRequestTarget is
set to Cp1252 as well.
The StringRequestTarget sets the content type to "text/charset=utf-8" by
default (possibly because the request is encoded in UTF-8 ?).
Setting a the content type parameter of the StringRequestTarget to
"application/json; charset=UTF-8" does not change the charset used by the
OutputStream, so you will send corrupt data. I don't think that the content
type should be set to "...;charset:cp1252" - if the web pages and the
request are UTF-8, the response should be UTF-8 as well.
Right now we are overloading StringResourceTarget (= cutting and pasting the
whole class, then applying our changes), so that we have a new constructor:
> public MyStringRequestTarget(String mimeType, String string, Charset
charset) { ... }
The charset is stored in a member variable and used in in onResponse():
> MyStringRequestTarget.onResponse()
> {
> ...
> stream.setCharset(charset);
> response.setContentType(mimeType + ";charset=" + charset.name());
> ...
> }
Could these changes be applied to Wicket / trunk 1.4?
Or am I missing something obvious?

Any suggestions?
That's why you need to add an AbstractBehaviour to each item. The
onComponentTag() method will be run before the component is rendered, so
you can check the state of your userObject and add/remove classes using
the tag.put() approach :)
Also, you might look into onNodeLinkClicked() method of the tree, if you
want to perform actions when you click on an item. The
onNodeLinkClicked() gives you access to the AjaxRequestTarget, so you
can also execute arbitrary javascript code, like this:
protected void onNodeLinkClicked(AjaxRequestTarget target, TreeNode node) {
MyObject myObject = (MyObject) ((DefaultMutableTreeNode)
node).getUserObject();
if(myObject.getMyState())
target.appendJavascript("targetTheComponentWithAJavascriptMethod(" +
getId() + ");");
}
Either that, or you could change the state of the userObject in the
onNodeLinkClicked method and add it to the AjaxRequestTarget. Your
AbstractBehaviour will then take care of visualizing the new state of
the object for you :)

Page models
Hi, in almost all my pages I set a model for the page and then need to retrieve it using the un-typesafe getDefaultModel(). Or I implement a typesafe getModel(). I was just wondering if others really normally use pages without models? If not maybe Page should be generified?

Re: AjaxEventBehaviour with request parameters?
I do it this way in openlayers contrib:
Request request = RequestCycle.get().getRequest();
String lon = request.getParameter("lon");
String lat = request.getParameter("lat");

StringResourceModel: use MessageFormat features without params array?
Hello mailing list, Short question: if my interpretation of the source code is correct, it is not possible to use StringResourceModel's MessageFormat features just with a single model (without passing a params array). If this is right: would it be a good idea to make it possible or is there a good reason that it is not, which I am not aware of? What I do not like about the Array way is that the message in the property file has not only to be aware of what was passed in this Array, but also in which order, which is not very flexible. WDYT? I have an idea in mind how this could be achieved and also would like to contribute... however, as I am not too deep into the wicket internals, I cannot promise my solution would be the most elegant one ;-) Cheers -- View this message in context: http://www.nabble.com/StringResourceModel%3A-use-MessageFormat-features-without-params-array--tp19177943p19177943.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Localization issue
Ok
This is my code for a locale switching link that will disable when active:
@Override
protected WebMarkupContainer getLocaleComponent(String id,
final Locale locale) {
Link link = new Link(id) {
@Override
public void onClick() {
getSession().setLocale(locale);
this.setEnabled(false);
}protected void onBeforeRender() {
super.onBeforeRender();
this.setEnabled(!locale.equals(getSession().getLocale()));
};
};
return link;
}
It works just fine, with 1.3.4 .
When using page parameter & bookmarkable links it looks like this, no
redirection involved:
protected WebMarkupContainer getLocaleComponent(String id, Locale
locale) {
BookmarkablePageLink bookmarkablePageLink = new
BookmarkablePageLink(
id, this.getClass(), getPageParameters(locale));
if (locale.equals(getSession().getLocale())) {
bookmarkablePageLink.setEnabled(false);
}
return bookmarkablePageLink;
}
protected PageParameters getPageParameters(Locale locale) {
PageParameters pageParameters = new PageParameters();
if (pageParameters.containsKey("locale")) {
pageParameters.remove("locale");
}
pageParameters.add("locale", locale.getLanguage());
return pageParameters;
}

not necessary:

Re: Localization issue
why the locale changes does not apply to the components? Are you setting up your components based on your locale in the constructor? Because if you do, then setting a Page object with setResponsePage won't create new component objects for you. Try: setResponsePage(this.getPage().getClass()); - this will forward you to a new instance of the page... - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Wicket resources (css, js and images)?
Sound like a good approach, I guess then if there were something like this components that would allow sharing of css etc (static css,js etc components) should just add to headercontribmanager, and ones that should not would just use the "old way". However it could be nice with some settings for this, sometimes it's just not feasible to merge like if you have a lot of components that are only shown 10% of the time or so.. richardwilko wrote: Hi, A few months back I started work on a slightly different method of adding resources to a page, where, it works out what resources are added on the page, combines them together with the yui javascript compressor, caches the result, and serves it. Unfortunately I haven't had any time to work on it as my new job has taken me away from wicket, but I am happy to share my rough code with anyone that wants it. :( and :) resources are added like so: HeaderContribManager.add(new ResourceReference(...), getPage()); and in each page add HeaderContribManager.getHeaderContributor(this.class, localString, styleString); in both cases put in the onBeforeRender method (the panels and such need to be added to the page before you can use getPage() afaik) Like I said its very rough, but it does have the advantage of producing a js file for each page, hopefully taking into account local and style, and should work when a panel adds javascript, and you use that panel in multiple pages. http://www.nabble.com/file/p19170189/HeaderContribManager.java HeaderContribManager.java <[EMAIL PROTECTED]> wrote: I've been hearing some rants on how merging resources can up the performance, should wicket be able todo this?

Re: getForm() on a component inside 2nd level Fragment returns null?
Ritesh Trivedi wrote:
Edvin,
Before posting, I already made Form a private member of the toolbar and
passed it from the parent fragment as a workaround.
My main question was - why didnt getForm() on the button work? and second -
not sure how you are saying markupProvider is the form? markup provider is
the page. My page markup file has the fragments. What am I missing?
Martijn answered the first one I see. Sorry for not stating it right away. I
was more focused on finding a solution for you :)
So to the markupProvider being your form: You wrote:
// Cart Header Toolbar
cartForm.add(new CartActionToolbar("cartHeaderToolbar", "cartActionToolbar",
ViewCartPage.this, cartForm));
And your only constructor in CartActionToolbar is:
public CartActionToolbar(String id, String markupId, MarkupContainer
markupProvider)
I didn't count the arguments, I just saw that markupProvider was the last argument, and also that cartForm was the last argument you passed into it. (God damned wrapping in the mail client confused me, I read your mail on the ASUS EEPC - not the biggest screen in the world :)
It seems you don't hit this constructor at all? :)
Anyways, a cleaner way to do this is to override the onBeforeRender() method of
the fragment. Then the component hierarchy is complete, so you can call
getParent() or even better, getForm() directly on the component to get the
form. Just remember to call super.onBeforeRender() as well :)
