Target unreachable '...' returned null primefaces

Boa noite, estou com o seguinte problema.
Estou usando primefaces + hibernate + jsf 2
Acontece que quando vou inserir o primeiro registro ele me retorna o erro do titulo, e não insere o registro. (target unreachable '#{medicoBean.selectMedico.nome}' returned null

Quando eu comento a parte que chama o método, ele insere normal os registros. Depois disso, volto o método, ele também causa o erro, mas se eu seleciono qualquer registro no data table ele volta a inserir normalmente. Ou seja, sempre antes de inserir tenho que ter um registro previamente selecionado. Segue abaixo os meus códigos
