Lukasz Lenart commented on WW-4345:
-----------------------------------

What's the problem here? I can figure it out based on the patch but I'm not sure if this the right solution as no one else reported such a problem. Can you share your setup or prepare a small demo app Maven based?

> 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.
