Primeiramente queria parabenizar a todos do fórum.
Está é a minha primeira postagem.
Estou tentando exportar um relatório do jasperreport para html um erro. Pelo que vi, buscando na internet, esse erro não ocorre somente neste caso de exportação, mas também em vários outros casos até mesmo não relacionados à jsf e jasperreport.
Segue o erro:
Exception in PhaseListener RENDER_RESPONSE(6) beforePhase.
