Subject: Deferring file downloads until link is clicked

 

 

Dear mailing list,

 

I’m having problems downloading documents using Seaside with Cincom Smalltalk 7.9.1.

 

I see that a document is downloaded during rendering whilst I wish that to be deferred until the user clicks op the link (anchor). On the Seaside website (documentation, FAQ, How to: entry 14) there is an explanation of how to resolve this problem by using a callback on the anchor:

 

Is there a convenient way to make the document be created after the link is clicked?

Yes, this is a common problem. One solution is to create an anchor and redirect:

html anchor
    callback: [
        self session returnResponse: (WAResponse
            document: anObject
            mimeType: aMimeType
            fileName: aString) ];
    with: 'Export'.

 

This information however seems to be outdated. There is for example no Class method WAResponse>>document:mimeType:filename , there is however an instance method with this name. I understand that I need to access the response in the active Request Context, but how do I do that?

 

Regards,

Which version of Seaside do you use? If you're unsure you can inspect
the following

GRPlatform current seasideVersion

In Seaside 3.x you'd use something along the lines of:

 self requestContext respond: [ :response |
        response
              document: anObject
              mimeType: aMimeType
              fileName: aString ]


Cheers
Philippe
