Estou utilizando Spring-data e Thymeleaf na minha aplicação, e quando tento submeter um formulário com campo do tipo Date sem preenchê-lo, obtenho o seguinte erro:
Failed to convert property value of type ‘java.lang.String’ to required type ‘java.util.Date’…
Acredito que é por causa do form enviar o campo data com valor vazio ao invés de nulo. Existe a possibilidade de enviar o valor nulo ao invés de vazio?
Segue alguns trechos do meu código: Classe person:
