Re: Drag/drop multiple items

[Maxim Solodovnik]

To be fair I'm not sure :(
This magic is hidden inside DroppableBehavior code :(
And I'm afraid my "drop" handler might be overridden inside
DroppableBehavior.onConfigure

Hopefully Sebastien can help here :)

Re: Drag/drop multiple items

[Martin Makundi]

Can you group them in javascript and detect group in wicket side, for
example as list of ids?

Drag/drop multiple items

[Maxim Solodovnik]

Hello Sebastien,

I'm trying to implement subj.
JS example I'm using as POC is here [1]
Everything works, except for one thing: no matter how many objects I'm
dropping I only have 1 onDrop() event inside wicket 

can you help me to fix/workaround this?
Thanks in advance!

ApacheCon CFP closing soon (11 February)

[Rich Bowen]

Hello, fellow Apache enthusiast. Thanks for your participation, and
interest in, the projects of the Apache Software Foundation.

I wanted to remind you that the Call For Papers (CFP) for ApacheCon
North America, and Apache: Big Data North America, closes in less than a
month. If you've been putting it off because there was lots of time
left, it's time to dig for that inspiration and get those talk proposals in.

It's also time to discuss with your developer and user community whether
there's a track of talks that you might want to propose, so that you
have more complete coverage of your project than a talk or two.

We're looking for talks directly, and indirectly, related to projects at
the Apache Software Foundation. These can be anything from in-depth
technical discussions of the projects you work with, to talks about
community, documentation, legal issues, marketing, and so on. We're also
very interested in talks about projects and services built on top of
Apache projects, and case studies of how you use Apache projects to
solve real-world problems.

We are particularly interested in presentations from Apache projects
either in the Incubator, or recently graduated. ApacheCon is where
people come to find out what technology they'll be using this time next
year.

Important URLs are:

To submit a talk for Apache: Big Data -
http://events.linuxfoundation.org/events/apache-big-data-north-america/program/cfp
To submit a talk for ApacheCon -
http://events.linuxfoundation.org/events/apachecon-north-america/program/cfp

To register for Apache: Big Data -
http://events.linuxfoundation.org/events/apache-big-data-north-america/attend/register-
To register for ApacheCon -
http://events.linuxfoundation.org/events/apachecon-north-america/attend/register-

Early Bird registration rates end March 12th, but if you're a committer
on an Apache project, you get the low committer rate, which is less than
half of the early bird rate!

For further updated about ApacheCon, follow us on Twitter, @ApacheCon,
or drop by our IRC channel, #apachecon on the Freenode IRC network. Or
contact me - rbo...@apache.org - with any questions or concerns.

Thanks!

.get() makes an Ajax call, so it doesn't return a value
You can use the callback methods (complete, success, failure) to get the
returned response from the server

But I think you don't need to use 'foo' from the server as a variable.
You really need: target.appendJavaScript("doNextStep(foo)")
I.e. execute something else once the Ajax call returns

Re: Error while calling Wicket from a JavaScript function

[James Selvakumar]

Hi Martin,

Is it possible to return a value from the ajax behavior while responding to
the ajax call?
I'm trying to do something like this in the server side:

target.appendJavaScript("foo");
>

And then try to use it in my JavaScript:

var foo = Wicket.Ajax.get({ u: window.callbackUrl });
> //do some processing with foo
>

Is this valid? Or is there a better way?

Thanks a lot Martin. You're right. I had something else in my code and
after I fixed it, I managed to make a ajax call from JavaScript.

Re: Error while calling Wicket from a JavaScript function

[Martin Grigorov]

There is no variable named 'a' in your code snippet.
It might be another problem.

Hi Martin,

I tried your suggestion but I'm still getting the same TypeError.

Re: Error while calling Wicket from a JavaScript function

[Martin Grigorov]

var wcall = Wicket.Ajax.get({ u: '${callbackUrl}'});
should be
var wcall = Wicket.Ajax.get({ u: window.callbackUrl });

Error while calling Wicket from a JavaScript function

[James Selvakumar]

Dear Wicket team,

I need to make a call to a Wicket page from my JavaScript function.
I followed the guide Calling Wicket from Javascript

and managed to define an ajax behavior to respond to the JavaScript call.

My ajax behavior looks like this:

> private final AbstractDefaultAjaxBehavior behave = new 
> AbstractDefaultAjaxBehavior()
> {
> protected void respond(final AjaxRequestTarget target)
> {
> LOGGER.debug("Received a request from client to get the encryption 
> key");
> target.add(new Label("foo", "Yeah I was just called from 
> Javascript!"));
> }
>
> public void renderHead(Component component, IHeaderResponse response)
> {
> super.renderHead(component, response);
> String callbackUrl = getCallbackUrl().toString();
> response.render(JavaScriptHeaderItem.forScript("var callbackUrl='" + 
> callbackUrl + "';", "values"));
> }
> };
>
> This callback url got rendered in the page like this:


> /* var callbackUrl='./wicket/page?0-1.IBehaviorListener.0-';
> /*]]>*/
> 
>


And here is my JavaScript code:

> var wcall = Wicket.Ajax.get({ u: '${callbackUrl}'});
> alert(wcall);
>
> But I'm getting the following error in the Wicket Ajax Debug Window:

*An error occurred while executing Ajax request:TypeError: a is undefined*

Can someone point out what's the mistake here?
