Hi all,
Calling NullpointerException index will be generated.

Click2.3.0-RC1 is used.
I hope that someone can help me.
Thanks

public class index extends Page {
@Resource(name="tService")
private TestService tService;
public String stest= "test";
public index(){
stest = tService.getTestMessage();
}
}

I modified a little your example ( for spring 3.0 but it shouldn't any
meaning)
package jp.test;
*@Component*
public class index extends Page {
@Resource(name="tService")
private TestService tService;
public String stest= "test";
public *void onInit*(){
stest = tService.getTestMessage();
}
}
and it works

Hi tomasz bandura,
org.springframework changed the TRACE.
'registered' but no, I do not know what to do.

Hi,
At the beginning, please try to change in logging.properties level to INFO to
be sure that your beans are already 'registered' in Spring context
