Hi there,
bumped into a weird problem. I allow users to download a file, pretty standard
code
===
WOActionResults downloadListing() {
WOResponse wor=new WOResponse()
wor.setHeader("application/pdf;
name=\"Listing\"","content-type")
wor.setHeader("attachment;
filename=\"Lisitng.pdf\"","content-disposition")
wor.setContent(... my data ...)
return wor
}
===
<wo:hyperlink action="$downloadListing">Get listing</wo>
===
This works like a charm. Nevertheless, the client wants to guard the download
by a JS alert; and if I change the template to
===
<wo:JSConfirmPanel action="$downloadListing"
confirmMessage="Really?">Get listing</wo>
===
I get this exception:
===
