Re: Wicket and JavaFX applet
Use Firebug and add a breakpoint in your JS to see if it is getting
executed. If it's not, you may try adding a semi-colon after your
"startApplet()" - because I don't remember if you need it when it's run in
an eval.

Wicket and JavaFX applet
Hi all,
I have problems with running javaFX applet inside wicket page. I call a
loading function from ajaxLink
(target.appendJavascript("startApplet()");) and in html:
http://dl.javafx.com/1.2/dtfx.js";
type="text/javascript">
function startApplet() {
fxstring = javafxString({
archive: "/neobax/TrafficApplet.jar", //placed in
root next to WEB-INF
draggable: true,
width: 640,
height: 480,
code: "trafficapplet.Main",
name: "TrafficApplet"
});
document.getElementById('taContainer').innerHTML=fxstring;
}
Last thing In ajax debug is:
INFO: Initiating Ajax GET request on http://dl.javafx.com/1.2/dtfx.js
INFO: Invoking pre-call handler(s)...
Is there any way to know more about the process for better debugging?
TIA,

Re: Type Inference for Wicket 1.4
What happened to the groovy wicket builder project? I know it was on hold
until anonymous inner classes were going to be supported which were added in
groovy 1.7 irrc.

Thanks for the great response! I will look at RefreshingView, but right now I'm considering yet another possibility.

Changing style in the same session with setStyle
Hi, I am using setStyle in the Session to set a "skin". I am using this setting to retrieve texts from resource files based on the skin. The thing is that a user might go to other pages during the same session. Other pages might have different "skins" so they are supposed to show other texts for the same keys. What actually happens is that altough other pages reset the setStyle to other values - the texts that are retrieved from the resource files are the ones associated with the FIRST style set in the session. This is really bad as I have all texts mixed up. What is causing this? Is it the resource file lookup that is set once for a session? Something else? Anyway around this? Thanks, Arie
RE: Interstitial window prompt then open a new window
You may want to look into this. I am using this to send a user to page
off our site via a link.
Link myLink = new Link("myLink") {
@Override
public void onClick() {
String url = "http://your_url";;
throw new
RestartResponseAtInterceptPageException(new RedirectPage(url));
}
};
PopupSettings settings = new PopupSettings();
settings.setTarget("_new");
settings.setWindowName("My Other Site");
myLink.setPopupSettings(settings);
add(myLink);
It does not have the interstitial window prompt but this may get your
closer to what you want.

We are needing an interstitial window that prompts a user if they want

I can prompt via a ModalWindow and capture their response...but what I
am not sure what to do now is open a window with the destination URL via
Ajax.
I like the target="_blank" behavior on an href...but this can't apply

Are there other options?

Re: Detect bookmark access to nonbookmarkablepages
Thanks for the feedback, Igor, nice idea.
About the page factory exception, in fact I have nonbookmarkablepages
mounted as if they were, just to makeup the url's, like this:
mount(new HybridUrlCodingStrategy("/pageA", PageA.class));
So that when the user enters PageA (no default constructor - non
bookmarkable), he gets on the browser's location bar:
http://myapplication/pageA[.x]
Maybe it's a little weird, but it's working for me :)
Cheers,
Xavier

Re: Detect bookmark access to nonbookmarkablepages
use a decorator, wrap the default factory, catch the exception,
transform it into something else.
although, if your users are bookmarking a non-bookmarkable url you
should get a page expired error. page factory is only used for
creating bookmarkable pages.

YuiMenuBarItem getMenuClass menu2
I'm trying to create a YuiMenuBar for my application using the ones in the menu2 packages. It works great, but I want to style one of the YuiMenuBarItems differently. I see there is an overridable getMenuClass() method, but there are 2 issues: 1. The only way to contruct a YuiMenuBarItem is through YuiMenuBar.addMenu(), so even if I create a subclass, it does me no good. 2. The getMenuClass() is returning "yuimenuitem", but the markup already has the class attribute set to "yuimenubaritem" and it is not being overwritten by the one in the component. Am I using these components right, or does YuiMenuItem need a setMenuClass() on it? I am using version 1.4.1.
Re: Bug in Page refresh?
Hi Wolfgang,
If I had to refresh the entire page on language change, I would not do it
with an Ajax Request, but with a normal one instead. I do not know how will
setResponsePage behave in a serverside Ajax callback. However, if you need
to do it with ajax, you should add the language dependent components to the
AjaxRequestTarget...
Hope that helped.
Cheers,
Xavier

Re: Repeating form on a page
Hi, I've been through a similar issue recently, also with a 'remove' button to delete elements from the list. I ended up using RefreshingView (that's the one I'd reccomend), and it worked nicely. However I'll expose the various solutions I've gone through, hoping to provide some background on the subject. I'd also be grateful on observations and comments on these, because I'm sure I'm missing something and there are still some aspects of these repeaters that I don't understand, so probably part of these thoughts are wrong :) In the first place, I used a ListView repeater. When clicking the 'add new' button, however, I found that all unsaved input entered on the other list elements was lost. That's because ListView refreshes the entire List with the backing Model objects in it's Model, and models were not being updated, as forms were not being submitted. So, I had to make the 'add new' link a submit button (skipping default form processing in order to avoid validation errors on incomplete data). However, to my surprise, same thing keeped happening (same for the delete button). Later on, I found about 'ListView#setReuseItems(boolean)', which solved the problem. But to my despair, the delete button always deleted the last element from the List. I still do not understand why, and still don't know what is 'reuseItems' really doing. (Any hints on that one?) Then, I was advised to use RefreshingView, and things were moreover the same, only that instead of having a Model given to the repeater, an Iterator had to be provided in an overriden method. In this case, a ModelsEqual ReuseItemStrategy had to be provided in order to keep the unsaved inputs in the forms when adding/removing. As a last appreciation, I have to say I hoped there was a specific component addressing this behavior, being it a fairly common arrangement... If one day I fully understand this I'd be happy to implement one myself, even if only for the sake of clarity in my code ;) Thanks, Xavier 2010/4/16 David Hamilton > I am new to Wicket (and have had great help from this community so far - > thank you).

Re: Repeating form on a page
The forms are all based on models. So, just make sure you use a different model for each form. I'd look into ListView, perhaps.

Re: AjaxSubmitLink javadocs
Every little bit helps - look how long it's been and nobody noticed it and
brought it to our attention - but it could have thrown some people off.
Thanks for the help!
I'll commit a fix this weekend when I get a few free minutes. :)

Repeating form on a page
I am new to Wicket (and have had great help from this community so far - thank you). My question here is that I'm trying to setup a simple contact form where a person may have zero or more contacts. My solution is to make the contact info a form within a panel. However, I need to repeat the panel form on the page for each contact (represented by a POJO I can bind to the form elements). I will provide and "add" button at the bottom of the list to allow them to re-submit the page and add a new empty object bound to a new form element. So my question is really two questions. 1) Is this best approach for this situation? 2) If it is, how do I bind each POJO on the list to a unique form instance? The goal is to allow each contact to be individually edited and saved. Any help is greatly appreciated.

Re: WicketRuntimeException: There is no application attached to current thread
Why not path the information you need to a runnable? and create a class you
use as context to communicate WEB and thread layer... IMHO that will be a
cleaner solution.

If you need an example on how to do this I can point you to a somewhat
similar example.

Re: WicketRuntimeException: There is no application attached to current thread
Do not use make references to components on the thread. Instead create an
instance of runnable to which you pass all the information you need and use
a kind of "context" to communicate with the Web layer if you need to pass
back information.

Re: WicketRuntimeException: There is no application attached to current thread
Component's getString method will try to get the laocalizer from the
Application, and the Application instance (singleton for a Wicket
web-app) is bound to the thread processing your request, not to the
one you have spawned off of it

WicketRuntimeException: There is no application attached to current thread
Hello guys!
In a page, I have a button. The button starts a thread, just like this, but I
get the exception in the bottom. Here is some code:
@Override

.getUser();
final File uploaded = new File(uploadFolder

fileUpload.getClientFileName());

fos.write(bytes);
fos.close();
logger.info("File written on " + uploaded.getAbsolutePath());
} catch (IOException e) {
logger.error("I/O Exception occurred!", e);
return;
}
final ImportListener listener = new ImportListener() {
public void info(String object, ImportMessage type) {
textModel.append(getString(type.toString()) + object + "\n");
}
};
importer.setUser(((AppSession) Session.get()).getContext().getUser());
importer.setDomain(((AppSession) Session.get()).getContext()
.getDomain());
importer.addImportListener(listener);
new Thread(new Runnable() {
public void run() {
try {
boolean flag = importer.importContacts(uploaded, null);
if (flag) {
BulkImport.this.info(BulkImport.this.getString("imported"));
logger.debug("User " + context.getEmail()

set focus on a field when opening a ModalWindow
Hello, Sorry to come back with this item, but I can't figure out how to set focus on a form element when opening a ModalWindow (iframe version). I tried to use target.focusComponent() within the calling page, but as components are created inside the called page, I can't have the right focusComponent() parameter. I also tried the FocusBehavior() class found on the wiki, but it works only for regular forms, not Ajax. I finally tried some javascript stuff within my called html page (something like frames[0].document.forms[0].elements[1].focus();), but this don't work bacause the iframe is not ready when my javascript is called. Does somebody knows how to set focus on my first form field in my modal window ?

And, nothing is stopping you from doing something like this in your
own code. I have a class called ComponentUtils where I put stuff like
this. I have two methods:
public static IModel modelOf(T bean);
public static IModel modelFor(Class
beanClass); // This will instantiate the object for you.
I also have:
public static void detachAllModelFields(Component c);
With static imports, you can just use these methods like they're in
your classes.

Bug in Page refresh?
We have a DropDownChoice to change the language of a page (the language
in mapped through an enum). The handler to change the code is as follows.
@Override
protected void onSubmit(AjaxRequestTarget target) {
getSession().setLocale(getLanguage().getObject().getLocale());
setResponsePage(getPage());
}
We just have 3 pages and a login page. The code works on 2 of 3 pages
but I don't know why it doesn't work on the third page (the code to find
the language and to get the current page seems also to be correct and
working). My question is does anybody have some hints what I could do wrong?
Regards,
Wolfgang

Detect bookmark access to nonbookmarkablepages
Hi there,
I'm trying to find an elegant way to detect the cases where a user tries to
access a nonbookmarkablepage with a bookmark. From the stack trace produced
in this case, I see this situation is handled in
DefaultPageFactory#newPage(Class pageClass), like this:
catch (NoSuchMethodException e)
{
// a bit of a hack here..
Constructor constructor = constructor(pageClass,
PageParameters.class);
if (constructor != null)
{
return newPage(constructor, new PageParameters());
}
else
{
throw new WicketRuntimeException("Unable to create page from
" + pageClass +
". Class does not have a default contructor", e);
}
}
I would like to present a custom page explaining the circumstances with a
nice link to the starting place where to navigate from.
I don't really like treating this situation as a WicketRuntimeException and
have it bubbling up to an internalerrorpage, because of the little
information on the exception thrown (i don't like identifying it by its
text, or nested exception type).
Unfortunately, DefaultPageFactory#newPage(Class pageClass) is final, so this
behavior can not be overriden. Is providing a custom implementation of
IPageFactory the best approach to this issue ? Any other way around ?
Cheers,
Xavier
Re: AjaxSubmitLink javadocs
Thanks for the answer, Jeremy.
I just created issue https://issues.apache.org/jira/browse/WICKET-2837.
I'm with you on what you state, it was obvious the only possible way to do a
submit without JS is to have an html submit mechanism, anyway, I was just
being cautious in case I was missing something.
I'm just glad to contribute improving this great framework, even though it's
on a lesser thing like this.
Cheers,
Xavier

Failing to remove item from list when drag and dropping
Hi, I have a use case that reads as follows: I need two lists next to each other. When starting up the left list is empty and I add items to it by dragging them from the right list and dropping them on the left. These items should be copied, (i.e. _not_ moved, the right list should be static) from the right list into the selected position in the left list. It should also be possible to reorder the items in the left list using drag and drop. The last thing is that you should be able to remove items from the left list by dragging and dropping them back to the right list. Since the right list is "static" the item should _not_ be added to the right list but rather just removed from the left list. After some investigation I've settled on using the YuiDDListView (from the wicket-yui project) which extends from a standard Wicket ListView. I've chosen this component since it supports positioning items in the list (i.e. you know to which index you dropped the item in the list). After MUCH hacking around I've managed to get most things working. There are mainly two things left and here I would really appreciate some help: 1) I cannot seem to remove _the last_ item in the left list (i.e. by drag and dropping to the right list). It works fine for all other items but for the last item it fails saying e.g.: Caused by: org.apache.wicket.WicketRuntimeException: component tabs:panel:panel:list:items:0 not found on page com.mycompany.MyPageCompany[id = 4], listener interface = [RequestListenerInterface name=IBehaviorListener, method=public abstract void org.apache.wicket.behavior.IBehaviorListener.onRequest()] at org.apache.wicket.request.AbstractRequestCycleProcessor.resolveListenerInterfaceTarget(AbstractRequestCycleProcessor.java:426) at org.apache.wicket.request.AbstractRequestCycleProcessor.resolveRenderedPage(AbstractRequestCycleProcessor.java:471) at org.apache.wicket.protocol.http.WebRequestCycleProcessor.resolve(WebRequestCycleProcessor.java:144) ... 28 more What causes this is that in the onDrop method in the left list I remove the dropped item from the list if it's dropped on the right list. Why is this happening? What's the best way to resolve it? 2) When I drag and item from the left to the right it looks like the item is added to the right list until I reload the page. I figure could be a javascript error since the javascript doesn't understand that the item shouldn't be added to the right list at all (it should instead be removed from the left list). What would be the best way to resolve this? I'm using Wicket 1.4.1. /Johan -- View this message in context: http://n4.nabble.com/Failing-to-remove-item-from-list-when-drag-and-dropping-tp1960968p1960968.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
