[Seaside] flow

[Robert Sirois]

Hehe yea. I was thinking the pdf could be embedded in whatever the response page is, that way you could preserve the navigation. Am I getting at what you're thinking Milan? Some sites open up new pages for printing things, too.

Embed what? In the end you still have to return a response and you can either return an HTML response or a PDF response... you can't return both. If you return a PDF, there is no way for the user to proceed further down that branch of the control flow (unless you were generating a PDF with callback links inside it :) ). It is, effectively, a dead branch, so #answering after returning a PDF doesn't make sense to me.



I'm still struggling to understand the flow that Milan is envisioning...

Mayhaps embedding it? It would be easy enough for the user to download then.

 but I'd question why you were using #call:/#answer: at all.



If the #answer is in response to a #show: or is triggering an #onAnswer: block in an embedded component, it should work fine to #answer inside the #respond: block.




Well, it's quite simple. I'm #call-ing a component which does a ticket reservation. After the user fills the form, in the callback of the OK button, I'm sending a PDF (the ticket) to the user and returning flow to the calling component. That's how I imagined it anyway.




But how can the user both download a file *and* see an HTML page displayed? You can only respond once to a request...
