Vaadin + Springboot + Designer

I create one class in Desinger:

public class NovaFicha extends VerticalLayout {
//Here I have panels, and textfields
...
}

and I Extend this class

@SpringComponent @SessionScope
public class NovaFichaImpl extends NovaFicha {
...
}

Then I create one View (in designer too)

@SpringView(name = PrincipalFirmasImpl.VIEW_NAME)
public class PrincipalFirmasImpl extends PrincipalFirmas implements View{
.. 
}

So in my PrincipalFirmasImpl I create one tabsheet, and one tab in this tabsheet is the NovaFichaImpl 

So When I try to run my app I got this error:

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [br.com.lumera.cartoriointeligente.ui.PrincipalFirmasImpl]: Constructor threw exception; nested exception is com.vaadin.ui.declarative.FieldBindingException: Field binding failed for tabNovaFicha

BeanInstantiationException

mabye try constructor inject the NovaFichaImpl before the view is created

@SpringView(name = PrincipalFirmasImpl.VIEW_NAME)
public class PrincipalFirmasImpl extends PrincipalFirmas implements View{

NovaFichaImpl novaFichalimpl;

@Autowired
public PrincipalFirmasImpl(NovaFichaImpl novaFichalimpl){
this.novaFichalimpl=novaFichalimpl;
}

 }
