Re: webRTC wickedstuff question

[Dmitriy -]

Hello Tobias,
I have a question about webRTC api.

The webRTC's standards doesn't specify any protocol for signalling purposes
as I can see here - Why is signaling not defined by WebRTC

.

The wicket stuff webRTC's api force to use web-sockets and socket.io
library, and node.js, I haven't any question here. But, what if I want to
implement my own signal server on java?

I can read node.js server's code and I'm trying to hack the protocol via
console in chrome browser and the net sniffer - wireshark.
I receive some strange packets. One with "::1" message, second with "::5",
next with google stun address. I think Node.js hides some protocols details
from me.

Can you explain what protocol use the wicket stuff webRTC api for signal
server? And how can I use webRTC api for example create webRTC peer
connection, send offer, receive answer and etc?

Re: Draggable multiple containment

[Maxim Solodovnik]

Hello Sebastien,
finally I found free time to continue this work :)

Actually my question was regarding "Droppable#onDrop, where you can reject
the Draggable item/component", how this can be achieved?

Re: AjaxFormSubmitBehavior, FileUploadField and nested forms.

[Martin Grigorov]

Hi,

I believe there is/was another ticket describing exactly your problem but I
cannot find it now.

The form id in the property key is not really needed.
You could use it to give Wicket a more specific message for particular
component.
You can remove it if this message should/could be used for any other Form
in you application/package/page/panel (depending in which .properties file
you have it).

AjaxFormSubmitBehavior, FileUploadField and nested forms.

[Fabio Fioretti]

Hello everybody,

I recently migrated an application from Wicket 6.17.0 to 6.23.0 and I'm
experiencing the following problem.

I have 2 nested forms. The inner one, form0, contains a FileUploadField
with an AjaxFormSubmitBehavior(form0, "change") attached to it, while the
external one, form1, wraps form0.

form1
|__
 form0
  |__
   FileUploadField

When the user selects a file and a file upload exception is thrown (e.g.
FileSizeLimitExceededException), I would expect form0's
onFileUploadException() method to be invoked. However, the one of form1 is
invoked instead...

As a result, Wicket starts looking for a property named
"form1.uploadTooLarge" instead of "form0.uploadTooLarge", thus breaking my
app, which only defines the latter.

Is this an intended behavior?

Was it introduced by https://issues.apache.org/jira/browse/WICKET-5753?

And, by the way, what is the rationale of having the form id in the
property key?

Many thanks in advance,
Fabio

Re: Browser/Client info navigatorJavaEnabled property returns undefined

[Sven Meier]

Hi,

please create a Jira issue.

Many thanks

Hi,

I was trying to use WebClientInfo to get browser information on the server,
In the Ipad chrome
when retrieving  'navigatorJavaEnabled' is returning 'undefined' instead of
true/false.

The problem is as  'undefined' is string but server is expecting boolean,
leads to exception and causing  browser to reload continuously.

possible solution

In wicket-browser-info.js
--
info.navigatorJavaEnabled = window.navigator.javaEnabled() || false;

Ramesh V
