Wicket job opportunities

2013-10-29 Thread Leonid Bogdanov

Hello!

    Sorry for bringing this topic, but I'm wondering are there any Software 
Developer positions that require Wicket knowledge and a remote work is an 
option?
    It would be double awesome if such position involves Scala/Clojure/Hadoop. 
I'll provide my CV on a request.

Thank you!

Wicket 6.7, AjaxCallListener.onPrecondition, prevent default behavior

2013-05-18 Thread Leonid Bogdanov

Hello!

    Could someone confirm that in Wicket 6.7 when a JavaScript expression in 
AjaxCallListener.onPrecondition() returns false, a default behavior for a 
corresponding HTML element isn't prevented?
    For example, I have an AjaxFallbackButton which corresponds to a button 
type=submit element on a page and even when an expression in 
AjaxCallListener.onPrecondition() registered for the AjaxFallbackButton returns 
false, a form with the button is submitted and the page with the form is 
refreshed. Downgrading to Wicket 6.6 solves this issue without any additional 
changes.

Thank you.

wicket-atmosphere issues

2013-03-24 Thread Leonid Bogdanov
Hello!

I'm playing with the wicket-atmosphere module and, while generally it 
works fine, I stumbled upon a couple of issues:

1) Suppose I have a Page with a method marked with @Subscribe annotation, 
this subscribtion has a filter attached. Is it possible to get the Page 
instance inside the filter to, e.g., access Page instance variables when 
deciding on event filtering?

2) It seems like sometimes empty Atmosphere messages are sent to a page 
when a filter rejected the specific message. For such events I have the 
following log record on the server
[Atmosphere-AsyncWrite-1] INFO  o.a.w.atmosphere.AtmosphereBehavior - 
onBroadcast: 0|msg|
and there is a JS error in a browser after receiveing the event
ERROR: Wicket.Ajax.Call.failure: Error while parsing response: Could not 
find root ajax-response element
What is the purpose of sending empty messages to a browser?

3) In my app Apache Shiro framework is integrated via a plugin adapted from 
fiftyfive-wicket-shiro project. User credentials are checked in an AJAX login 
form. In order to prevent a session fixation attack there is a call to 
invalidate old and create new session right before credentials check:
getSession().replaceSession(); // inside AjaxFallbackButton.onSubmit()
After integration with Atmosphere this code no longer works, an exception in 
thrown on login attempt:

22:11:41.698 [qtp18908406-24] ERROR o.a.wicket.DefaultExceptionMapper -

Re[2]: Forward request to an external filter

2013-02-18 Thread Leonid Bogdanov

Hello, Martin!

    Thank you for your response! Actually I already use Scribe lib, but 
indirectly - through Shiro OAuth plugin.

Thank you.


Monday, 18 Feb 2013, 10:06 +02:00 from Martin Grigorov mgrigo...@apache.org:
Hi,

Wicket doesn't provide an API for internal forwards. Use the Servlet API
for this.

Also check  https://github.com/fernandezpablo85/scribe-java for OAuth. It is
very simple to use it.

 traditionally with RequestDispatcher.forward()?

 Thank you.

Hello, Martin!

    I think such article would be helpful to many others, so if it's not too 
much trouble, please, write about it.

Thank you.

Hi Leonid,

I have no experience with Apache Shiro.
I can blog about how to use Scribe directly in Wicket if this will help you.
