Re: File Downloading in Tapestry
If you still uses this Bayeux component I can tell you that I have upgraded
the component library to match tapestry 4.1.1.
Further I have added a StreamLink (like the download link, but can take more
than one parameter). The name stream is more correct as it can stream any
data not just as a download.
The same goes for StreamAsset that is suitable for streaming images - like
charts and so.
Cheers,
Jacob von Eyben
