which adds items,
My problem is that when you clik on calcular abandons modalpanel

What I want is that the independent commadbotton the form to continue doing some independent calculations to fields


thanks

Hello Dernard

Another cuestion please
How can I keep track of twice panelModal
of the code is as follows entityhome
public class DetalleCompraHome extends EntityHome<DetalleCompra>
.
.
.
 @Override
    public String persist()
    {

        this.getInstance().setDmsCantidad(this.getInstance().getDmsCantidad());
         this.getInstance().setItem(this.getInstance().getItem());
         System.out.println(this.getInstance().getDmsCantidad());
         System.out.println(this.getInstance().getItem());
          String s = super.persist();
         this.getInstance().setDmsCantidad(this.getInstance().getDmsCantidad());
         this.getInstance().setItem(this.getInstance().getItem());
         System.out.println(this.getInstance().getDmsCantidad());
         System.out.println(this.getInstance().getItem());
          String s1 = super.persist();
        return s+"D";
    }

I have no idea

Sorry for my English ... I do not practice
My challenge is learn English and seam framework.

Indeed.
By submitting form ( <h:form id="guardar"> )
I have a copy of DetalleCompra and persist both original and the copy.
