[tobago] Implementing excel export example leeds to blocked ui
Hi,
I'm using tobago 1.0.10 release on JBoss 4.0.5.
I just implemented an excel export as it is shown in the examples. The
output is generated correctly, a file safe dialog is shown (in firefox 2
on a linux box) and the file is saved. But the UI stays in the "blocked"
state (the running squares). Is there a way to redisplay the page the
user came from?
Code from my controller:
public String export() {
String attachmentName = "workbook.xls";
LOG.info("export called, generating " + attachmentName);
FacesContext context = FacesContext.getCurrentInstance();
Object response = context.getExternalContext().getResponse();
if (response instanceof HttpServletResponse) {
HttpServletResponse servletResponse = (HttpServletResponse) response;
servletResponse.setContentType("application/vnd.ms-excel");
servletResponse.setHeader("Content-Disposition", "attachment; " +
attachmentName);
List<Entry> list = dataService.getData();
workbookService.export(list, servletResponse.getOutputStream());
}
context.responseComplete();
return null;
}
The method is called as an action from a <tc:button>.
BTW: do you know a way to get the attachment name (variable
attachmentName) as the suggested name in the file save dialog? Firefox
suggests the jsp filename (which is editor.jsp in my case), I'd prefer
"workook.xls".
Regards,
Stefan.

Hello,
IMO you currently cannot produce 2 different results. Therefore you will
have to disable the transition effect for the command like this:
<tc:button label="Export" action="#{controller.export}" transition="false"/>
If you are setting a target attribute like "_blank" the transition is
disabled automatically.
Regarding the content disposition. In the past I had some problems with
this, too. I have to check how I solved it back then. Looking at the RFC
I see there is a parameter name missing. Perhaps the following works::
Content-Disposition: attachment; filename=workbook.xls

Arvid
