Bom dia a todos.
Tenho uma vo com um atributo data do tipo GregorianCalendar.
Na hora de gravar no banco beleza, mais quando vou listar os dados gostaria de converter para um formato legivel tentei com a tag
<f:convertDateTime pattern="dd/MM/yyyy HH:mm:ss"/>mais ñ consegui vem o seguinte erro
Caused by: javax.faces.convert.ConverterException: Cannot convert value 'java.util.GregorianCalendar[time=1158778234298,areFieldsSet=true,
