> Unfortunately, I'm passing this ticket on to you second-hand so please bear with me.
> Since at least version 2.3.3 we have had a problem with Struts and multipart/form uploads.
The problem is intermittent and we'd had a really hard time getting it to occur consistently
on all our servers, but it seems to happen pretty reliably on Red Hat.
> The problem is basically this: When a multipart upload is received by Struts, the action
responsible for the request is instantiated without any information about the upload. We expect
to get the file name/type/content as per:
but get null values instead.
> We were able to track the problem back into the org.apache.struts2.dispatcher.Dispatcher
a while back and circumvented the issue as you can see in the attached patch ... but we don't
know enough about Struts to figure out if a fix should be applied elsewhere.
> It's entirely possible we're using Struts wrong, but we tried pretty hard to find the
right upload configuration and couldn't get reliable results until we patched.
> Please let me know if need more information to reproduce the problem. Our CMS is behind
a firewall, so I can't point you to a live page but would be glad to give you more details
about the JARs we use and how we have Struts configured.
