Re: Error - MultipartIterator: no multipart request data sent

[Mikael Eriksson <mi...@bea.com>]

Hello

 I noticed the same problem when moving to 1.0. It seems that
the requesthandler notices that the request is a multi-part and
tries to find the multi-part data, even when the request are
already handled and you are only forwarding to the next
action. (I only got the problem when going to another action.)

 The way I handled it was to set redirect="true" in struts-config.xml
for the action that I forwarded to, this made the multi-part info
go away from the request (and all other parameters too of course,
so if you are expecting request parameters in the next action this
will not work.)

 I guess this could be fixed in the code too, maybe by having the request
reader setting a request attribute so that it knows the next time
that it already has gotten the data. But I did not go deep enough
into the code to know if that is feasible or not.

 Regards
 Mikael
