Re: Firing ajax request while returning a StreamResponse

2013-04-24 Thread Lance Java 
Split it into 2 phases:

Phase 1: Submit form
Do the work (webservice + version increment)
Generate a link to the generatePDF event
Return the page to be re-rendered

Phase 2: Re-render the page
Use javascript to download the PDF once the page has loaded.

Re: Firing ajax request while returning a StreamResponse

Hi Lance, I think I'm with you most of the way with the exception of
generating a link to the pdf event.

So I'm returning PurchaseRequest.class in my onSuccess method which would
for the page to reload with context from onPassivate, this should resolve
my sync issues. Where I'm lost is how to trigger the script to call the
StreamResponse. I thought maybe this could be done in the url like so,
http://domain/purchaserequest/958:generatepdf. I'm just not sure what the
appropriate way of doing this is, or how to do it at that. I'm assuming you
would need some sort of business logic to prevent people from just using
that same URL over and over again. How would you tigger the script on
return?

Thanks Lance.

Something like this (not tested)

@Inject
private ComponentResources resources;

@Inject
private JavaScriptSupport jss;

@Persist(PersistanceConstants.FLASH)
private String pdfUrl;

@SetupRender
void setupRender() {
if (pdfUrl != null) {
jss.addScript(document.location.href = '%s';, pdfUrl);
}
}

void onSuccessFromForm() {
long pdfId = doWorkPriorToPdfGeneration(...);
pdfUrl = resources.createEventLink(generatePdf, pdfId);
}

StreamResponse generatePdf(long pdfId) {
// generate the PDF
}

If you don't want to use flash persistence, you can use page activation
context or a request parameter etc.

Ah yes, I didn't even give flash persist a thought, I think I'd rather use
that to minimize url tampering. Thanks Lance.
