> Struts Dispatcher gobbles up request parameters

> 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: http://struts.apache.org/release/2.3.x/docs/file-upload.html 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.
