 Otherwise you'll end up with one additional behavior for each render -
 stupid copy-paste error :/.
 
 BTW this might be an additional candidate for the new Wicket 8 lambdas:

Re: Getting the model

2016-04-01 Thread Martin Grigorov
I've added an example with
https://github.com/apache/wicket/commit/2417322673238d57a794c237e84dd5dacf890804

I think we should explain that those are just convenience. It is better to
use the "old way" one cares about memory usage. I'll add it soon.

Hi,

would be great to see some information how to use lambda models in the user 
guide.

kind regards

 Since you are in #onComponentTag() there is no reason to add a Behavior.

 It sounds like you always need the model.

   }
 }

 In the second constructor I can use the supplied model to determine to
 add
 the negative class. However in the first constructor I cannot find a way
 to
 access the model.

 What am I missing?

[7.2] ContextRelativeResourceReference

2016-04-01 Thread nino martinez wael
I am having a hard time getting the ContextRelativeResourceReference to work.

I thought it was supposed to grab the specified resource from the web
container relative to where the wicketapplication where mounted.

In my case my directory layout are like the attached image.

And I have configured jetty like this:

// Static resources
String staticPath = "src/main/webapp/";
ServletHolder resourceServlet = new ServletHolder(DefaultServlet.class);
resourceServlet.setInitParameter("dirAllowed", "true");
resourceServlet.setInitParameter("resourceBase", staticPath);
resourceServlet.setInitParameter("pathInfoOnly", "true");

sch.addServlet(resourceServlet, "/webdialer/*");

I have also tried without the "webdialer" part, and the leading slash.
Jetty does server the resources just fine.

I am using the config:

ContextRelativeResourceReference("css/lavish-bootstrap.css")

Here are the error I am getting:

Last cause: The requested resource was not found: /css/lavish-bootstrap.css
WicketMessage: org.apache.wicket.util.resource.ResourceStreamNotFoundException:
The requested resource was not found: /css/lavish-bootstrap.css
