How to create a JMesa checkbox with Java

[Carlota Viña]

I work with JMESA , JAVA and I need a checkbox

I have the following code Java

      HtmlColumn activo = new HtmlColumn("activo");

            activo.getCellRenderer().setWorksheetEditor(new CheckboxWorksheetEditor());

            activo.setTitle("titulo");

            activo.setFilterable(false);

            activo.setSortable(false);

            htmlRow.addColumn(activo);

When I run the project I get the error

    java.lang.IllegalStateException: Not able to convert the value for the checkbox.

     Causa

     Not able to convert the value for the checkbox.

How can I create the checkbox with java and jmesa?
