[Resolvido] Problema com checkbox numa jTable (AbstractTableModel)

Eu tenho uma tabela que tem um AbstractTableModel associado a ela. A primeira coluna é uma checkbox.
Eu gostaria de saber por que motivo não consigo selecionar as checkboxes que adiciono nesse modelo. Observem que no código abaixo o método isCellEditable retorna true para essa coluna e mesmo assim não consigo selecionar.

package br.com.lgc.realtime.gui.model;
