Re: OnChangeAjaxBehavior: nth character
Steven,
Start with something like this:
zipcodeField.add(new OnChangeAjaxBehavior() {
@Override protected void onUpdate(AjaxRequestTarget target) {
// do your stuff here
}
@Override protected IAjaxCallDecorator getAjaxCallDecorator() {
return new AjaxCallDecorator() {
@Override public CharSequence decorateScript(CharSequence script) {
return if(this.value.length % 5 == 0){ + script + };
}
};
}
});

Hi,
I
would like to add AJAX behavior to an application that sends an update

For example, if the user is entering a zipcode, I would like a callback

I've
written code using OnChangeAjaxBehavior that sends messages back to my
application after every character has been typed, such as the following:
final TextFieldString zipcodeField = new TextFieldString( zipcode );
form.add( zipcodeField.setRequired( true ) );
OnChangeAjaxBehavior zipcodeUpdated = new OnChangeAjaxBehavior() {
�...@override
protected void onUpdate( AjaxRequestTarget target ) {
System.out.println( Zipcode value: +
zipcodeField.getDefaultModelObjectAsString() );
}
};
zipcodeField.add( zipcodeUpdated );
I
could check to see the size of the zipcodeField (in this example), but
it makes my application more chatty than it needs to be. I also tried
using onblur, which works fine, but does not satisfy my business
requirements:
final TextFieldString zipcodeField = new TextFieldString( zipcode );
form.add( zipcodeField.setRequired( true ) );
AjaxFormComponentUpdatingBehavior zipcodeOnBlur = new
AjaxFormComponentUpdatingBehavior( onblur ) {
�...@override
protected void onUpdate( AjaxRequestTarget target ) {
System.out.println( Zipcode value (form component): +
getFormComponent().getModelObject() );
}
};
zipcodeField.add( zipcodeOnBlur );
Prior
to using Wicket (which I'm currently prototyping for my company), we
would handle this logic in JavaScript (observe changes to the field and
when the user enters the fifth character then we made an AJAX call back
our Struts 2 application.)
What is the best way to achieve the same end using Wicket?
Thanks, in advance, for your help!

Proposal for a general solution to integrate a javascript-api
Looking for a smart way to integrate wicket with extjs (http://www.extjs.com) i wrote a small piece of code, that can be used to generate javascript function-calls. The idea is to rewrite the public api of the javascript library in java. Everytime you call one of these java-functions a equivalent javascript function-call will be generated and automaticalliy (can be done with a proxy or annotations+aspects) written into the (ajax)responsetarget. There is a small 14kb maven eclipse project attached with a proof of concept for this idea. http://rapidshare.com/files/350028986/WicketAjaxRpc.zip For the Ext-JS integration some feedback would be very useful, and i am planning to make it public if you support this proposal. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Good evening, I have a BookmarkablePage which may need PageParameters or not, depending on the business workflow. I used to mount it under /page but now that we do use the PageParameters-providing constructor I have a problem which forced me not to mount the page in my Application class anymore. When I mounted the page explicitly, the PageParameters constructor call used to gave such an URL: /page/param/0. So when asking for a resource on that page, it gave me this error message: URL fragment has unmatched key/valuepairs, responding with 404. If I don't mount the page, the URL generated is of the form: /bookmarkablePage?class=fooparam=0. Which is good regarding the parameter retrieval. My question is: is there any way to have the best of both world, I mean such a pretty URL as /page (no Java class name in the URL) and the parameters using the classical '?' and '' symbols? Which would give this URL: /page?param=0. I guess that if I don't have any trailing slashes in the URL, the URL fragment message should be avoided, isn't it?

How to hide / show additional descriptive Row below empty DataView?
Hi all,
How is it possible to dynamically show and hide an additional dummy
row No items to show below a DataView?
I tried this with code similar to code below but it does not work even
though isVisible() is called. I have a small testcase ready to go.
It's quite basic so I must be missing something obvious.
Many thanks
Bernard
In a DataView, with an AjaxFallbackLink delete action, in onClick I do
something like
item.setVisible(false);
target.addComponent(item);
target.addComponent(emptyRow);
with emptyRow as follows:
final WebMarkupContainer emptyRow = new
WebMarkupContainer(emptyRow){
@Override
public boolean isVisible(){
return rowProvider.size() == 0;
}
};
emptyRow.setOutputMarkupId(true);
add(emptyRow);
In HTML:
tr wicket:id=dataRow
td wicket:id=IdID/td
tda wicket:id=deleteDelete/a/td
/tr
tr wicket:id=emptyRow
td colspan=2No Items to show/td
/tr

AjaxPagingNavigator and mounted pages produces incorrect links
I just filed bug: https://issues.apache.org/jira/browse/WICKET-2743 I have a 2 mounted pages, one mounted at home and one mounted at page2. When clicking a BookmarkablePageLink for home the browser is sent to the correct page. The home page then uses a DataView to create many panels with BookmarkablePageLinks to page2. If you paginate using AjaxPagingNavigator the links in the panels incorrectly point to /home/test/foo/page2. Where test/foo was a pageparameter sent to the page. It could be user error, but I think thats a pretty standard use case. Does anyone else have errors with generated urls for mounted pages when using ajax? I just tested this on 1.4.5 and it works correctly. -Ryan - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Generics for datatable columns
This is a stupid minor thing but I was wondering. If I have a datatable of SubClass objects, shouldn't a I be able to add an IColumnSuperClass to the list of columns? Not very often used, but could be useful occasionally like for inheritance with domain entities. Couldn't hurt to implement this right (just add a generics wildcard)? - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: How to hide / show additional descriptive Row below empty DataView?
two suggestions,
1)emptyrow.setoutputmarkupplaceholdertag(true) instead of
setoutputmarkupid(true).
2)you can use dataview.getitemscount() instead of data.size() as later can
be expensive.
