JSf - Erro de Cast

Programação Java
#1

Pessoal…

Estou recebbendo este abaixo.

javax.faces.FacesException: #{ListTransactMB.rastrear}: java.lang.ClassCastException: br.org.system4.entity.Transact cannot be cast to br.org.system4.entity.Transact

No cast abaixo…

 public String rastrear(){
        
        br.org.system4.entity.Transact t = (br.org.system4.entity.Transact) this.getDataTableBinding().getRowData();
         
        System.out.println("  Transact :   "+t.getTransactid());
        
        //Object ob = this.dataTableBinding.getRowData();
        
       // System.out.print("Objeto "+ob.getClass());
        
        
        return null;
    }

Mas no codigo comentado, eu vejo que a classe que está vindo do dataTableBinding é esta mesmo… “br.org.system4.entity.Transact”

Já passaram por algo parecido ?

abraço e valeu.

Segue o codigo do datatable e do MB

Pessoal.

Ainda náo identifiquei o problema, mas troquei a maquina e resolveu…

Achei estranho depois de que uma rotina que já funcionava faz tempo parou também.

Abraço.
