Hola, a ver si alguien me puede ayudar. Tengo un jtable compuesto por 2 columnas. En la 2, hay un botón que al pulsarlo ejecuta la función eliminarCategoria pasandole la fila a eliminar del jtable. El caso es que me da error ArrayIndexOutOfBoundsException. Si no utilizo setCellRenderer y setCellEditor en la tabla, solo manipulando sobre el DefaultTableModel directamente, va bien. Dejo el trace del error y el código por si es de ayuda. Gracias.
