Is it possible that it's a bug that the stream gets requested multiple times? Or if it is by design, why? I can't see a reason for it.
I also cannot only return a new IResourceStream when it's not instantiated yet in my ResourceStreamResource, because the AttachmentInputStream from Ektorp is not serializable, I get errors if I try that. As far as my knowledge goes I see myself with no option left.. 2012/8/17 Michael M <generi...@gmail.com> > Thanks for the idea, but I can't do that.
