Olá desenvolvedores, minha dúvida é a seguinte: posso ao clicar em um botão redirecionar a página que estou e ao mesmo tempo abrir uma nova aba no navegador com um relatório carregado.
o contexto é o seguinte, preciso emitir planilhas de inspeção de pragas. Para que uma planilha seja lançada preciso fornecer alguns dados como propriedade e talhao a serem inspecionados, e também a % de plantas a serrem inspecionadas. Portanto criei uma página com um form, onde insiro essas três informações.

</h:form>
</div>

</ui:composition>
Ao clicar no botão emitir, as informações referente a planilha inseridas no form, são persistidas no banco, e uma nova aba é aberta com a planilha pronta para impressão. No entanto gostaria também que quando clicasse no botão além de persistir os dados e abrir a nova guia com a planilha eu precisa redirecionar a página do form para uma página principal.
Como posso implementar tal fnuncionalidade ? do jeito q está agora a pagina do form continua como estava no momento do click no botão.
segue o MB e alguns erros que aparecem no lado do servidor mesmo funcionando no lado do cliente.
