You cannot send a PDF and a HTML page in one HTTP response.
What you have to do is send a page containing a JS that opens a browser
window with the link to the PDF.
Object onSuccessFromSavePrescription() {
// savedata
return AnotherPage.class;
}
In AnotherPage:
void beforeRender() {
String linkUrl = componentResources
.createEventLink("showPdf").toURI();
jsSupport.addScript("window.open('%s')", linkUrl);
}
StreamResponse onShowPdf() {
InputStream is = prescriptionPdf.pdfGeneration(patient, visit);
return new PDFStreamResponse(is,"Prescription-"+visit.getId());
}
