Re: WicketMessage: Can't instantiate page using constructor 'public com.mycompany.StartPage()'. An exception has been thrown during construction!

Hi,

apparently your injection isn't set up correctly, thus managerLocal is null.

Please take a look how the CDI example does it in wicket-examples, e.g. 
the following is missing at least:


new CdiConfiguration().configure(this);

Have fun
Sven

It is my Wicket class:

 public StartPage() {
 managerLocal.addPerson();

Maybe someone knows what's wrong? Thank you for any advice.
