Calling wicket from javascript
Hello,
I'm new in this forum, and i love wicket!!!
My question is:
What wrong with this code?
@Override
protected IAjaxCallDecorator getAjaxCallDecorator() {
return new
AjaxPreprocessingCallDecorator(super.getAjaxCallDecorator()) {
private static final long serialVersionUID = 1L;
@Override
public CharSequence preDecorateScript(CharSequence
script) {
return function callWicket(){ + script + };
$('.search-div').slideDown('slow',callWicket());;
}
};
}

Re: Calling wicket from javascript
Hard to say without details. Are you not getting the behavior you expect
(and what is that behavior?). Are you getting an error message?

Re: Calling wicket from javascript
I tried to call wicket from javascript without using a wicket behaviour, and the error/warning i get is wcall is not defined. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Calling-wicket-from-javascript-tp4614627p4614859.html Sent from the Users forum 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
Wrong path to wicket-event.js resulting in 404 after calling wicket from javascript
Hallo,
I came across strange problem I do not know whether it is mine fault or
wicket's problem.
On a page, there is a widget, which list news records.
Each record has an edit and delete link. Edit link opens new dialog in jquery's
thickbox window, which is practically IFrame.
The code for page, which holds form and which is displayed in the thickbox
window:
http://pastebin.com/m5ca60e78
The code for a link, which shows the thickbox window with a page in it:
http://pastebin.com/m6339b3a
En example usage:
http://pastebin.com/m768350aa
here on line 72 when I do:
target.addComponent(ShopNewsWidgetPanel.this.get(news-container));
after ajax refresh of the component, which contains news records, each record
containing edit link, there is 404 error found in the Ajax debug window.
From firebug console I can find out that if I add a some component (here it is
edit link, which is held by news-container), which also contains
AbstractDefaultAjaxBehavior, then upon rendering head of the response, there
is wrong path to wicket ajax resources:
Correct path:
http://localhost:8080/cz.madewithlove/app/resources/org.apache.wicket.markup.html.WicketEventReference/wicket-event.js
Wrong path after ajax call:
http://localhost:8080/cz.madewithlove/app/shop/rozkovec/resources/org.apache.wicket.markup.html.WicketEventReference/wicket-event.js
The page is mounted like so:
mount(new IndexedHybridUrlCodingStrategy(shop, ShopModulePage.class));
An ajax function, which is called in the page's ajax button onSubmit() method:
function thickbox_window_close(url)
{
tb_remove(); //removes thickbox window
// call url of the behavior, this behavior is attached to the link, which
opens the page in thickbox window
var wcall=wicketAjaxGet(url, null, null, function() {return true;});
return !wcall;
}
I could solve it by visiting all components of the parent container except
behaviors and add them to the ajax request target, but it would be better to
not bother about it and just add the parent container. Any pointers?

Re: Wrong path to wicket-event.js resulting in 404 after calling wicket from javascript
I believe the code that causes the problem is
#
@Override
#
protected CharSequence getURL()
#
{
#
return super.getURL() +
String.format(TB_iframe=trueheight=%dwidth=%dmodal=false, getHeight(),
getWidth());
#
}
IFAIK wicket encodes URL parameters in a special form. And the last part is
the number of ../ required for prepending the resource urls. In your app
it might be zero so wicket do not generate appropriate ../../.. for your
app/shop/rozkovec mount string.

Re: Wrong path to wicket-event.js resulting in 404 after calling wicket from javascript
I have tried removing the override completely, but it did not help. I just
would like to know, whether I am doing something obviously stupid, or if I
should start debugging deeper or make a quickstart.

if you fix the NullPointerException in your ErrorPage the original
RuntimeException (which would possibly tell you what you were doing wrong)
might had a chance to get through
