It's been this way since struts 1.0 (and likely prior to) but http
requests carrying multipart/form-data posts result in an exception being
thrown if forwarded through more than one action.
(e.g request flow)
1 - submit multipart/form-data request (with at least one file input)
request is forwarded to ActionOne.
2 - ActionOne handles multipart data, writes a file to disk does
something with other parameters etc. then forwards to ActionTwo.
3 - Exception is thrown.
This occurs in the following versions I've tested 1.0.x, 1.1-b1. Copies
of the exceptions follow this post.
Workaround, never forward to a second action, always forward to a .jsp
which must be the end point for the request after the first action.
(This kind of sucks).
If this is a bug then consider it submitted, if it's designed this way
then how about changing it? (pretty please?)
Thanks
Rob
